[ROM] Mecool M8S Pro LB Stock & Nano Nexus ROM (Android 7.1)

[Guest]

In the spirit of the Pure Nexus Project, these Nano and Stock Nexus ROMs prove that less can be more. The goal is to keep true to Google's vision and use the bare minimum of OEM or third-party apps or add-ons, which can be added ? la carte by the user as needed. These ROMs also serve as a foundation for TVStock Nexus ROMs, which deliver the pure Android TV experience using the Open GApps TVStock Package.

Download:

• Nano Variant: BURN PACKAGE (962MB IMG file), OTA UPDATE (507MB ZIP file)
• Stock Variant: BURN PACKAGE (1.31GB IMG file), OTA UPDATE (743MB ZIP file)
• Flash burn package with Amlogic USB Burning Tool v2.0.8 or BootcardMaker v2.0.0.2

Notes:

• This firmware is designed for the newer M8S Pro LB variant with the Broadcom BCM4335 wireless chipset. If you install it on earlier (LQ) hardware, WiFi and Bluetooth won't work. (The variant should be the last two letters in the string above the bar code on the bottom.)
• The underlying OEM firmware for this build is pre-rooted, so this is too.
• The updater is signed, and so can be installed in the Update app, the stock recovery, or TWRP. It's designed for incremental updates, since user data is preserved. If you're installing for the first time, you should include a data wipe.
• The safest bet is always to install the full Amlogic burn package with USB Burning Tool. With no reset switch, you can trigger USB detection by typing "reboot update" in a terminal window.
• The local terminal app shows after being enabled in Settings->Developer Options.
• Flash ROMs at your own risk and always remember to back up your data first. The burn package includes a factory reset.

Hi,
thank you for the great ROM. I have one problem with the Rii i8 + bluetooth keyboard. The connection will succeed but that's all. The problem is probably in the Bluetooth HID drivers. I found the same problem here and Beeling solved it. http://www.bee-link.com/Beelink-248-1-1.html
I'm afraid Mecool will not deal with it. If you ever had time I would like to try to solve it.
Thank you
Petr

Hi, because the Rii i8 + does not work, I bought the EVOLVEO WK29B BLUETOOTH KEYBOARD http://www.evolveo.com/en/WK29B unfortunately does not work either.
Is there a working keyboard?

i use a Victsing keybord with pad and i think the logiteck k400+ does work (i'm on stock for the moment)

Installed this ROM and everything works fine. Except Youtube, the audio keeps cutting off after 2-3 minutes. Anyone else facing this issue? Any thoughts on how to fix this?

Correction, same issue with Netflix as well

[san_ic]

Same issue on all apps. Even when I cast to the box from my phone, the audio cuts off after a few minutes. Any ideas?

I just got mine a couple of days ago: Mecool M8S PRO L S912 Android 7.1 TV BOX Amlogic 3GB+16GB
Is this image ok for this model. If not then whats the latest for this box please?
Cant install TWRP as there is no reset button on newer models.
Also is there any update on this audio issue yet.

Thanks Magendanz for the ROM, installed yesterday and everything works fine for know. In my opinion much better then stock ROM, finally i can install all apps from google play and you have little support from me.

Perhaps an older version of youtube may resolve it? That's what i'm using now

Guest Can i outright update the OTA firmware without flashing?

I'm not sure what you mean here. You flash firmware, whether it's an OTA update (.zip file) or burn package (.img file). You mean without wiping user data? Generally, you can do incremental updates of the same custom ROM without wiping data, but it's always safer to start with a clean slate.

[sasa2k0]

OTA update from USB stick works with no problem, 'clear cache' and 'wipe data' must be ticked and that's it.

Even if the one installed is newer then the usb stick. Rom
