    Did anybody try this on their m8s? I am really excited to see a Lollipop firmware!

    I’ve tried but it doesn’t work for BCM 4335/ OTT TV Box πŸ™ Sadly it doesn’t work for me.

  3. 1 Bigbouble said:

    Finally I tried the firmware but it didn’t work on mine either. It loads fine but then comes to a black/gray screen making flashing and then the flashes stop and leave you in a black screen and a working mouse pointer but nothing else..

  9. 1 indus_rich said:

    This firmware bricked mine too but managed to get back 4.4.2 by using USB Burning Tool, Bootcard Maker (U-boot), toothpick switch and pin short (pin 16-17 flash) all together. Nightmare.

  13. 1 Cor said:

    hello, I’ve tried the firmware for my M8S but it’s not the right one… it says I need n200 firmware image (not n200c)…
    Please help!

  14. 1 sky said:

    Bricked mine too.

  15. 1 cns said:

    This firmware works in M8S+ that I bought in Aliexpress (chinese TV box )?

    CPU Amlogic S812 Quad-Core Cortex A9 de 2.0 GHz

    GPU Mali-450MP GPU @ 600 MHz

  16. 1 cns said:

  17. 1 Frederick stead said:

    Hi I have a Android M8s box,quid core Cortex A5 and GPU Mali 450, software 4.4.2 software,Will your software update for M8S 812

    work on my box, thank you.

  18. 1 Mats said:

    Although this firmware did not work “out of the box”, it was very useful to get a fully working system. See what I did on

  19. 1 hobbes said:

    hi mats, why i am getting a E:footer is wrong and E:Signature verification failed/ Thanks!

  20. 1 Nicko said:

    I have m8s android Box ap6330 with android 4.4 and i want install android 5.1.Which of this firmware is for my box?
    Thanks for help

  21. 1 jephte said:

    that firmware do not work on m8s ap 6330.

  22. 1 Mats said:

    @hobbes: Are you using the “toothpick method” when installing the firmware? Without going into much technical detail, the Acemax firmware installer wipes everything when using the “toothpick method”. In this case that is a very good thing. For the second stage flashing (using the Acemax firmware as a skeleton for the DevDigitel Rom), you must use TWRP, which can bypass signature verification.

    @Nicko: My M8S is also AP6330 WiFi. I suggest that you follow the guide I posted previously. Good luck! πŸ™‚

  23. 1 David said:

    I have Goobang doo M8S bought from amazon.. Does this firmware works? Mines needs an update and the supplier does not answer my questions..

  24. 1 Nicko said:

    @Mats it is very you have youtube video for easy install.or another easy tip?Thanks
    Are you swedish?

  25. 1 Mats said:

    @Nicko I do not have a Youtube video for this, in my own opinion the instructions are written in a clear and direct way. As far as I can tell there is no easier way to do this. In reality the software does a lot of very advanced things under the surface.
    Yes, I am born in Sweden, but living in China now for the past 9 years. Love it πŸ™‚

  26. 1 Nicko said:

    @Mats i mean if you can do changes in the files and upload two diferent files. So i can install first one file and later second file

  27. 1 antonio1 said:

    I tried it last night and I think I did it forever, the blackbox M8S doesn’t want to boot again, even the power led does not light anymore, just a short flash of light when I plug the power. What can I do now? Why happen this to me?

    Try this method

  29. 1 antonio1 said:

    @danyrolux I’ll try according to the link indicated, I hope I can rescue my OTT M8S, I really miss it. I know the caution is there, but which one of us could know what is really doing as soon as a huge package of software can’t be checked just like that.
    I will let you know the news, I hope to make it back to live again.

  30. 1 Mats said:

    @Nicko Sure, here is a link to the two files that need to be on the root of the SDCard for the second flash.!JEAClJzA!xVTIi7ZeZi7KOTIlcjEtEg

  31. 1 Mats said:

    I have now updated and simplified the installation guide, see this post for more information:

  32. 1 antonio1 said:

    It seems that I have no chance to recover my m8s, this upgrade killed the device forever. If there is anything to try, it will be nice, but I still have no hope.
    thank you,

  33. 1 Mats said:

    @antonio1 These boxes are practically speaking unbrickable. What you need to do is to short some pins on the NAND memory and then you can flash it again (I had to do this myself several times when trying different ROMS). Try just searching for “m8s short pins” on google, it will give you all information you need. In my case I needed to short pins 29 and 30. Good luck!

  34. 1 Alieno said:

    Hi Mats, Thanks a lot. I have Akaso M8S:

    1. Is it possible to install on this box Android 5.1 using your method?
    2. Can I revert back to original Android 4.4 ?
    3. Sorry for my ignorance but what is TWRP needed for the remote control?


  35. 1 danyrolux said:

    I am not sure, since I don’t have your device…

  36. 1 Mats said:

    1. Maybe. What WiFi chip does it have? What firmware are you using now?
    2. Yes, but be aware that you can run into the problems that antonio1 has. A backup/confirmed original firmware is an absolute must before trying these things.
    3. TWRP is needed for the second stage flashing. Remote control is optional (you can extract the necessary files already from an existing Kitkat 4.4 ROM yourself). My M8S box has a remote control just like the picture you can see at the top of this page.

  37. 1 Alieno said:

    Hi Mats, thanks for your reply. How can I check the chipset of the WIFI? Should I open the box and look at the motherboard? Or there is an app which tells me that? Thanks

  38. 1 Mats said:

    @Alieno Yes, open it up. Also check the NAND chip etc. Google is your friend.

    Just by a quick search is seems that there is a quite exotic Realtek chip (RTL8723BS). So Wifi and Bluetooth will most likely not work, assuming that the system works otherwise. That may or may not be showstoppers for you.

  39. 1 Jack said:

    Where are the instructions how to install this? I downloaded the file and try to install but installation always aborts as if the file is corrupt. I am using the file:
    file size: 489,095,168 bytes

    My TV box model is M8S


  40. 1 donniedubh said:

    @Mats: does this work for the BCM4335 Chip as well? Anyone try it on a cheap clone with BCM4335 yet?

  41. 1 Mats said:

    @donniedubh I have asked for feedback, but so far none. I think that most likely it will work with BCM4335, so why don’t you try and let us know? πŸ™‚

  42. 1 Mats said:

    @Jack You need to have all 5 files in the root of your SDCard, and then use the toothpick method.

  43. 1 donniedubh said:

    @Mats unfortunately my OTT box is tricky… it doesn’t go into recovery mode and the only way I can hook a flash off SD is using bootcardmaker… and even then it’s spotty at best. No probs with USB burning tool. I have to use bootcardmaker to hook the Acemax firm in Step 1… it shows the android robot and loads the firm into NAND but then blue light + black screen = nothing. Please elaborate: “this firmware will boot, but later just hang at a flickering background” How far along does it go in the boot process?

  44. 1 Mats said:

    @donniedubh It does the full initial boot:
    1. White Android logo on black background
    2. Initial installation of apps
    3. First start of the GUI, which crashes
    4. Stuck at a flickering background (changes when you move the mouse)

    So what I did was basically replace the system by using Team DevDigitels Universal S8xx ROM. That way I could make it work.

    Sounds like you could maybe run this, by always booting off the SDCard?
