How to install VXP face in NO.1 G8


No.1 G8 is MT 2502 smartwatch which is supposed to support VXP face. But as you read in the previous post about G8, there are many new features in No.1 G8, like blood pressure, three modes, outdoor functions(air-pressure, temp, UV), etc. There are too many new features which take up the storage space, there is no more space for vxp faces.

A MT2502 watch doesn’t support vxp face? That’s crazy. So we decide to develop a new firmware for the vxp faces, but we can’t increase the storage, we must cut some features to release the storage. The SIM card feature/mobile data will be banned in the new firmware, that means you can’t use it as an independent phone(but bluetooth calling is OK).

To use this firmware, you need to upgrade to the latest firmware manually. How to make a firmware upgrade, please check this tutorial And be aware, the battery life should not be less than 80%.

I just downloaded and installed several watchface, both of them work well. But this firmware still need some optimizations, so please wait for a few days. Any news I’ll let you know.

Good news! The new firmware which supports vxp face releases! You can download it here.

And sorry about the convenience, if the sim feature is needed, we’ll keep on working, later we’ll develop the new firmware which supports both of the vxp face and sim feature.

  1. Hi! Thanks for your work. I have a new G8 and I’m hope you can make this new firmware work properly. I have a question. Is there any way to have notifications of whatsapp with a preview of the message?

    1. Hi Sarmihiel, we’ll release it soon, but the whatsapp notifications, nope, whatsapp doesn’t work with MT2502 watches.

  2. The function of SIM card feature/mobile data it is necessary to leave. This is important for many.
    Please better to remove not needed functions: outdoor functions(air-pressure, temp, UV) and can reduce many languages. For example to write only English and Russian for the Russian speaking countries (over 15 countries), English + Chinese, English + Arabic, etc.

    1. Thanks for this suggestion. Because this chip supports Bluetooth calling so we think independent phone feature is not so important. And the outdoor features, the language packages, most people need the outdoor feature when they go out somewhere, we have already created 6 or 7 firmware, if we separate to more firmware, we’ll need to release dozens of firmware and after firmware release we also need to maintain all of them.

      1. If you remove the function calls that they are the same as S9 and G6. But outdoor functions still take data from the Internet and on the phone they are easier to see.

        1. Three mode and the blood pressure, outdoor functions these are all new features. But your are right, outdoor functions take data from internet.

          1. Why the additional data is not used, the slot under microSD memory card? This may resolve the memory problem

      2. Paul Sandin (pasa0001)

        I bought the watch because of the bt tether AND standalone capability. I do not agree that it is not important to have only one option

        1. Hi Paul, I think you are talking about the custom watchface, don’t worry, we’ll keep on working, we’ll create new firmware which supports both sim feature and custom watchface feature.

  3. Hi. 8)
    Some things are very annoying in the current firmware, a few FR:
    1) Be able to choose the language of the interface not depend of the switch “synchronization”
    2) Be able to choose “Time format” not depend of the switch “synchronization”
    3) Be able to choose the interface language in Fundo applications

    WBR. 8)

    1. Download the correct firmware which supports your language, go to the clock, there you’ll find it, it depends on your phone’s language.

  4. Hi. The Fundo Smartdevice app is not compatible with my mobile device. Is there any other way to change the watchface in G8?
    (I have already install your new firmware version)

    Thank you and keep up the good work.

    1. Hi Neton, it is the compatible issue between Fundo wear and Fundo Smartdevice, you just need to uninstall the Fundo wear.
      And about how to install vxp face, please wait for the new firmware release. (the one you installed is the language package)

  5. OK my mistake! I tough that you already have released the new firmware.

    We just have to wait those few days.


  6. Hello, i have bought No1 G8. Unable to Install watch faces. Please suggest the way how can i install?

    1. Hi Ravi, if you read this post, you’ll find that the stock firmware doesn’t support vxp face. 🙂 Please read before asking.

  7. Paul Sandin (pasa0001)

    Really? Blocking the sim to get a watchface. That will never happen. If at least the watch faces on the watch looked like in your commercial pics, or could be exchanged so I only had my own face and could delete the ones installed, that would free up memory?

  8. Željko Trogrlić

    I need SIM feature; there are some other functions that are not very usable, like Outdoor (at least fetch real weather forecast), Masasger and even Calendar (agenda from Google calendar would be more useful). I would be even happy without watchface download if you add one elegant monochromatic face that can be used with black strap. White/gray analog face is not readable.

    1. Thanks for your suggestion, don’t worry the new firmware which supports both SIM feature and the vxp face is developing.

    1. Hi Ildar, it is because MT 2502 doesn’t support OTA. Check the tutorial and make a firmware update manually.

  9. Just received my no.1 g8 and tried to install vxp faces but after I came across this article gave up.. anyway eagerly waiting for the firmware update so that I can use both sim function and vxp faces

    1. I wish you wouldn’t remove the SIM capability, it’s very useful when it’s not convenient to carry a phone. These chinese watches are usually packed with fake apps, perhaps you could remove those instead. For example I bet blood pressure and heart rate are fake value generators as usual, those could go. Looking forward to a new firmware that allows for the use of the SIM.

      1. Don’t worry, the new firmware is developing. Thanks for your suggestion, but Chinese watches are not that bad, the heart rate sensor is real, the function works well.

  10. Hélder Correia

    I can’t even get my PC to detect the G8 and install drivers… Do I need a special cable for connecting the watch to the PC or a regular USB cable (like the one that came with the watch) is enough?

    1. Hélder Correia

      Ok, another cable solved the problem!!

      Some sugestions to the firmware: Bring back the 3 modes; Delete Outdoor, calendar, blood pressure (is simulated right? the watch only measures Hart rate via optical sensor, right?) and ringtones.

      As for calendar if you manage to get google calendar integration it would be sweet, like it is right now is useless.

      A priority should be your FunDo app it drains battery on the phone it needs work, serious work, right now I’m using Mediatek SmartDevice app.

      1. Currently, the new watchface firmware doesn’t support the phone/sim feature, but don’t worry, we’ll keep working on it. Thanks for your suggestions.

      1. Hélder Correia

        Thanks, it was some bad contact in the cable, probably got damaged in the shipping, swapped the cable and everything went smooth, great tutorial really easy to follow. One question, is there a specific place to discuss and learn about the FunDo app (the phone app)?

  11. just got my G8
    2 questions:
    1. where i can cancel the option to answer calls on the phone ?
    when the phone is conected i canwt answer the calls on the phone, only in the watch.
    2. wich app i can install on the phone that i can track my sport info ?

    1. Hélder Correia

      Your 1st question: Go to bluetooth settings in your phone, then click no G8 watch and then turn off the “phone audio” option, with this turned on the G8 will act as your phone loudspeaker by default.

  12. Hi! Is it possible to just replace the pre-installed faces and sounds in the official ROMs? Is it something that could be done easily (i.e. via ADB) by an non-expert user?

  13. Please help me bt notification and bt message also not working in new firmwear but vpx working perfect please give me suggestion thankyou

    1. This is because of the Fundo smartdevice problem, check the app to see if the bluetooth connection is stable. Fundo wear is much better for notifications.

  14. please remove vu, massager, bloodpresure, and drink for more space and add sim, facebook and whatsapp app in new frimwear thankyou

          1. Hi Onaid, we received such feedback, so we took one for test but it works for us, when I sent a message to cheery, her G8 lights up and notifies her.

  15. Hi,
    is it possible to have continous HRM and connection to google fit in order to be able to perform sport activity sessions?
    right now Fundo has nothing like that and more over hr rate is not working at all

      1. HRM not working on both fundo wear and mediatek, simply the heart rate sensor is not recognized by the app so it’s never recorded, I’m using the vxp firmware

        1. Ah, yes, the app can’t record the heart rate results. It can only measure the current heart rate.

          1. not even that, there is no measure button and touching anywhere doesn’t trigger anything,

  16. is there any alternative to fundo wear to be able to use tracking fitness activities? the HR on the phone is quite good and it’s a pity not to be able to track activities with a GPS, just like you runtastick or mi band notification apps

  17. Hello Jon, I have updated the latest firmware which support both sim and watch faces. But after update sim feature still not working. I am unable to make or receice calls. One vxp side only one or max two watchfaces are supported. It shows only 1 language english which is good. And just for info sim feature was working erlier. Hope your will work to solve the issue and gives us the best workaround.

      1. hi can somebody please guide me how to update the latest firmware which can use both vxp faces and sim function. ty

      2. i cannot even download the new firmware link you provided in my computer.. pls help and oh its about my no. 1 g8.

          1. hi. again when i try to connect the watch thru usb cable it says driver not found… how can i install the driver to my pc

  18. Guys, you have multiple links, both here, and in the official website,

    Please, try to maintain both pages and websites and make sure that they have the same download links. Leave the LAST UPDATE DATE showing somewhere so customers know which is the latest.

    Indicate what is what. Should one install both Watchface firmware and the separate smartwatch firmware? If both, is there a correct order? If not both, can it be clear what each firmware achieves?

  19. Добрый день, подскажите как установить vps прошивку я обновил, а vps как установить не пойму?

  20. Is there a way to change the directory where BT photo shots go? Mine are going to AndroidMedia, but I want them to go to DCIM with the rest of the photos. Thanks! Also, anybody have any luck with the new firmware getting both VXP watchfaces and SIM function to work? The only comment here about it makes me worry I’ll lose the phone function.

  21. Hi Jon, please, help me! I’m brazilian and I got this this 1 week ago in my last trip to Paraguay. Today I tried install the new firmware with watchfaces but I could not and now I can’t turn my watch on, the visor is totally black and my pc (windows 10) is not recognizing my watch! please, help me to fix it!!

  22. Hi,
    I installed new firmware with watchfaces and no sim, all worked well.
    Now I’m trying to install new firmware with watchfaces and sim but pc does not recognize watch (I try on windows 10 and 7),impossible to update watch.
    Please help needed.

          1. Hi, how can I upgrade firmware manually?Do I have to use Flashtool?
            Thank you

  23. I’m a bit confused as how to update the firmware on the G8 watch

    I’ve downloaded and extracted the files to my PC following the link given at the top of the page. I’ve pasted it here, just to check it’s the correct link

    I’ve found the following instructions

    1)Download the firmware on our official website.
    2)Extract the file and open the firmware update tool folder.
    3)Find the Flash_tool exe on FlashTool folder and click twice
    4)Click the Option and select the USB Download/Readback(Data card)
    5)Select Format FAT(disabled) then a message shows up on your screen. Tick up the Format FAT and click OK button.

    I’m stuck on instruction 3 as I cannot find the Flash_tool exe or the FlashTool folder.

    It does not seem to be in the compressed file G8vxptest.rar

    What should I do now?

  24. Titas Mondal

    Got a G8 smartwatch, but when I try to open flashtool.exe to , it doesn’t open. Getting foreclosed evertime. Please help !!

  25. Hi Jon,

    how can I get full access to the files of my G8 per USB?
    I can´t open any folder or files of it.
    Maybe I can replace the visual-files direktly on my watch.

    Thanks a lot

      1. does it means i cant install other watchfaces if i have an iPhon 6 and only the fundo wear app?
        In the toturials you need other apps to install vxp-faces after run the new firmware.
        all these apps doesnt exist on apple shop.

  26. If at a later stage i decide to use the SIM feature, can i get back to the original software version? Also, any luck with continuing SIM feature and VXP faces?

    1. Hi Raj,

      Yes, you can download the original firmware and make a firmware update manually, so you can use the SIM feature. The firmware with SIM feature and vxp faces is still not clear, don’t know if the engineer could make it. 🙁

      1. Also, before anything i tried calling through the watch but it doesnt work. What do you think is the problem? I havent done anything yet & was trying to use the SIM feature . Please advise. Thanks

  27. At in coming call it isn’t show name of caller, just show phone number. Is it possible to show name instead of phone number?

    1. Hi Akos, go to bluetooth settings on your phone, then delete all the other devices except the G8, try again, you’ll find it can display contact name.

  28. Andrew Christian

    Hi, I want to flash the sim and watch face firmware for my G8. Is it safe for me to install and use? And how much vxp watch face i can install? Thanks

  29. hi…my no.1 g8 screen has become blank and watch display is gone… i tried on and off but it will only vibrate… pls help. i think sweats leak inside from back cover while roaming outside in hot weather… is there any possibility to restore the display?

    1. Hello longkum, did you try firmware update? If it is because of the sweats, I’m afraid you can’t fix it.

  30. Hi
    I bought a GS8 (and after many attempts to get it recognized to the PC) I updated the firmware following your tutorial to be able to add new watchfaces. Now I can add up to 4/5 watchfaces. There have also been changes in the smartwach like the continuos heartrate, a new menu to turn off bluetooth and above all it can no longer be used as a phone standalone. I had this in mind but when after few weeks I tried to reinstall the original firmware I did not succeed! The smartwatch is no more recognized by the PC even after hundreds of attempts to plug/unplug the usb cable ….
    Now is it not possible to update the fiirmware or go back to the original one? Why?

    1. Hi Alex, once you can update the firmware via your pc, your pc is supposed to support firmware update now. My suggestion is, first, turn on the G8 and connect it to your pc, then the PC will detect the watch and reinstall the drivers again. Second, change the port, turn off the G8, press download then plug it to the port, make a firmware update. Hope it works for you.

  31. please inform me about new firmware which updated vxp facewatchs, facebook and whatsaap notifications thankyou 🙂

    1. There is new firmware which supports vxp face, but you need to abandon the phone feature…. G8 supports facebook and whatsapp notifications. Please download the latest fundo wear app.

  32. Boa noite ,primeiramente obrigado por desenvolver firmware para nós. Aguardando o novo firmiware com SIM e as watch faces. Obrigado

  33. Hi! I cannot understand at all, which firmware should I install to have watchfaces? It is stable? I don’t want to use the sim feature, for now.

    Thank you in advance!

  34. my watch is g8 : I try to update the firmware the result can not make a call. and I flash back with the old firmware still can not make calls and other phone mode. please help.

  35. Hi many thanks for developing this firmware with vxp face support 🙂 Just ordered my g8 which will take a few weeks to reach uk 🙁 I prob wont use the internal sim but is anyone able to give any feedback about how much memory is available for faces in the sim & no-sim versions. I realise that each face may use different memory resources.
    Many thanks & a Happy New Year to all.

      1. Hi Jon, thanks for answering my query. I read that the stock firmware had three faces available and assumed that the newer g8 firmware versions might allow more memory for vxp faces. No problem though, three is still enough.

        1. Hello Jamie, the new VXP firmware has the same memory as the previous. It is a new driver update, not big update. 🙂

  36. My G8 arrived this week and I’ve been checking for info on firmware updates. From what I’ve learned the G8 & Gs8 are exact same but have different straps. But the firmware page has different versions for “New TP”. What is the new TP and how can I tell if I have that model? thanks & regards

  37. Hi! Thanks for your work. But i have No.1 GS8 when i connect it to usb its only charging no other indicator for new hardware nothing at all only charging . what i had missed ??? I am using win 10 ..

  38. I received my G8 Today, i flash to new firmware but after flash to new firmware my G8 touchscreen can’t be used!!!

    1. I had the same issue.
      Updated the newest firmware (
      and then no touch functions, and no more connected to the computer (Tried on win10 and winxp) when I try to connect, it only charges.
      Anyone has any useful idea? Restore the previous firmware? Reset? Uninstall the driver from computer?
      (this was written from the correct email address)

  39. Hi, I bought a gs8, I want to use the vpx spheres, but I need to use the sim functions, what is the fimware that I should use? Thank you

      1. ok thank you, is that I had read this …

        “Update! We developed a firmware which supports VXP face and the sim feature, you can download it here.”

          1. Thank you very much for your time, one last question, if I flash the vxp faces firmware, can I go back to the other firmware and use the sim functions?

  40. Alexander Gutiérrez

    hello friends I bought the No.1 G8 change the rom for the watchface and sacrifice the sim because I do not need it, and everything works perfectly, there is only something I could not do,
    have if jon can tell me what is the app that I use to synchronize the data of pressure, elevation and UV
    please be very grateful.

  41. Hello, Jon. Can you give the source code of this firmware ( – I’ve found this watch is really good idea, but all firmwares you listed are unstable (Bluetooth connection crash every 3-4 days, sim-function crash just by switching watch-mode (phone-watch-phone) etc).
    I think we (open source community) can eliminate that bugs and add some good features.
    If it is a trouble, we don’t need all part of the source – gsm, vpx, heartrate & pedometer in that way as it is in vxptest.

    1. Ah, Andrew, thanks for your suggestion, but the engineers will not provide the source code, I know we need a better firmware, but because of the limitation of the storage, we can’t do many change for it.

    1. Hello Makdlog, I can download and unzip the file, I can also use the flash_tool to open the file. Please download it again, the link is correct and the file is OK.

      1. Hello jhon i have same problem with makdlog when i downloaded the latest firmware file ‘NO.1_G8_B_new_tp_WF.rar’ from ***
        The file is corupt or damage.

  42. Daniel Tique

    Hola buenas tardes hace poco adquirí mi reloj G8, es perfecto solo lo utilizo como reloj pero ahora quiero cambiar de esfera o face pero según lo que he leído se necesita cambiar de firmware, quisiera que me ayudarán para saber cuál firmware descargo y así mismo saber cuáles son la ventajas y desventajas, gracias un saludo desde Colombia. Espero su pronta respuesta!

  43. Hi, just received the G8 after waiting for G9 for long. Can someone pls guide me the procedure to install watch faces on G8 as it doesn’t connect to my laptop when I tried to follow some tutorials on the website.

  44. Thank you for the quick response..I did download all on my PC & went till step 12 & done. What do I do next to get the watch faces on the smartwatch please?

  45. Thanks, I followed the procedure & downloaded Mediatek Smart Drive & downloaded 3 watch faces & moved them to appmanager as advised but none of them seem to install saying unknown error? What can be the reason as the watch was connected to the phone & battery was fully charged?

  46. Thanks Jon..I followed steps from 1 to 12 on Page 1. Do I need to follow & install the drivers from page 2 as well? I though after step 12 on page 1 everything is done.

    1. Hello Jayesh, if you can update the firmware, you don’t need to install the drivers in the page 2.

  47. Thanks Jon..I installed 3 watch faces & seems to be working well. Due to the phone & bracelet function gone the motion sensor doesn’t work’s even after changing the settings to there a way around that? Also the pedometer keeps running while sitting in the car as well so not sure what is the problem.

    1. Hello Jayesh, thanks for your report, the problem maybe it is the G-sensor. But since you said it works, you can go to the settings to turn it on.

  48. Can not get any of the fundo apps to install on my samsung galaxy s8 active, they download fine try to install but fail.

    1. Hello Dan, Fundo wear is not compatible with Smartdevice. You may need to delete the Smartdevice. 🙂


    Olá, Existe alguma maneira de calibrar o G-Sensor? Acho muito desconfortável o ângulo padrão para girar o braço.

  50. Does this custom firmware, fix the issue when using the stopwatch, and the screen goes black, when you wake it up again, you have to go all the way from Tools-Stopwatch, instead of directly to it?

      1. Hey how can I delete some of the original apps of my g8 to make more memory in my smartwatch..this should be available to us since it is out devices we should choose which apps we wanna use n the ones we don’t want we can delete..can I please tell me how to delete some of the features in my g8 dat I don’t use or need.

  51. Hello, Is there any way to calibrate the G-Sensor? I find the standard angle to rotate the arm very uncomfortable.

  52. I can not connect the watch to a computer. It does not detect any drivers, and there is a 10 error after manual installation

  53. Hi, I have just ordered a new No.1 G8 watch from Ali Express. I am a newbie to Smart Watches. Can you tell me how do I get Watch Faces into my G8. Thank you

  54. What if when I flash the G8 with the smartwatch is on while connected to PC (not shut down), what happen? because my G8 not detected by the PC when off (shutdown).

  55. Got a problem on fundo whereby it doesn show ” Application ” in the setting menu. Could anyone enlighten me on this? Tq

  56. Hello Jon. Have a problem when installing the watchface in Mediatek Smartdevice. The process of installing seems to be not working. it says installing your smartwatch it may take a few minutes..please wait………..but it doesnt.. Any solution Jon?

  57. Hi. I have my new G8 smartwatch for Christmas, and I need to install the watchface firmware to add more vxp watch faces. The problem is that the USB lead that comes with the watch appears to not provide enough power to boot the watch. It power on/off/on/off when plugged into my PC – so I can’t connect the watch to flash it 🙁

    I tried other usb leads. Most do not fit as they can’t get close enough to the watch, other fit but will only charge the watch.

    I have tried 3 different pc’s, powered usb hubs etc. The watch wont boot up for flashing with the provided cable 🙁

    If I power the watch on first, the cable will work and my PC sees the watch ok – but the flash tool will not connect to it.

    Any help will be appreciated.



  58. Hi, I look forward to hearing about new firmware supporting both sim and watchfaces. I just bought it, the watch is great with sim function, I’m not willing to throw it away, but having newfaces could be nice. I also have a question, when I don’t read the notification right when it pops up, i’m having that little white icon on top of display… where do i find all the missed notifications and can read them? Thank you

  59. Hi, Just got the G8 watch an followed your instructions for the firmware. All worked great but how do I get new watch faces? I’m using an iPhone so the fundo app instructions don’t apply.
    Is there a way of installing new faces via windows 10?

  60. Hi,
    I need to firmware NO.1 G8 smartwatch with English and Arabic support, flash_tool and drivers but looks that there are deleted from your website and google drive and i cant find them.
    can you help me?
