[ROM] Mecool M8S Pro L 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 à 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.

Stock Nexus variant includes:

• Open GApps Stock Package
• All contents of the Nano Nexus variant

Nano Nexus variant includes:

• Open GApps Nano Package

Known Bugs:

• You can enable the nav bar in Settings->Display->Statusbar, but may need to toggle back and forth before it will show.

Download:

• Nano Variant: BURN PACKAGE (930MB IMG file), OTA UPDATE (479MB ZIP file)
• Stock Variant: BURN PACKAGE (1.46GB IMG file), OTA UPDATE (824MB 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 earlier models of the M8S Pro L with the QCA9377 wireless chipset. If you install it on later (non-LQ) hardware, WiFi and Bluetooth won't work.
• 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. (This must be revealed by clicking Settings->About->Build 7 times.)
• Flash ROMs at your own risk and always remember to back up your data first. The burn package includes a factory reset.

Great work, thanks!

I'll think I'll try both new ROMS (ATV and non-ATV variants!

How can i install this rom by OTA update? I have the nexus atv rom and it doesn't have the update app that come with stock Rom. Thanks.

You need to install it in TWRP recovery. From Terminal app (enabled in Developer Options), type "reboot recovery", hit Install, pick .zip file, and swipe to install. If Developer Options isn't enabled, you need to click Build number in About 7 times.

Note: I'm working on my own Update app that will also include a button to reboot to recovery.

Amazing work, this rom is perfection was able to install nano via ota and it fixed every problem I had with the box!!! at least imo, any suggestions on getting this box to connect to amlogic usb tool? I can connect my W95(s905w) and older Sunvell Q-Box(s905), and a Beelink MiniMX III just fine, but this box will not show up on any version of the tool I have tried, intel i5-6400, win 10 home, any tips or tricks?

Well, the problem is that you've got to press the reset button when connecting via the USB OTG port...and there's no reset button. It can be done, but you've got to short the pins on the PCB where the switch would be installed. (Awkward!)

Some Amlogic bootloaders such as the Beelink GT1 and Shiningworth All-in-One for Amlogic q201 reference board don't require you to press the reset switch, and it seems like that would be the way to go here. I'll suggest it to Videostrong.

This would be very important! Already have some news?

What do you mean with suggesting to Videostrong? Can this be changed for the actual boxes which the users already bought?

Guest is it not possible to create some software (an app or tool) to simulate the same thing as doing on hardware-side pressing the reset or shorting pins to reset?

I don't feel confident or competent enough to attempt a firmware update on this box; knowing me if I attempted to do so I'd certainly brick it! I have two issues with this box; it runs very hot and it has the android tv play store and not the google play store ....is there anything I can do about either of these issues?

Well, I feel much better now that we've got the burn package (.img file), know the pin locations to short for Mask ROM mode, and know that doing that doesn't wipe the Widevine L1 keys. If you brick your box, it's just a "soft brick" and is recoverable. You'll just need to crack the case.

The heat issue is a tough one to solve. Use the builtin Chrome browser and search and download Aptoide app for all the apps you need. You will need a mouse or air mouse to use the Chrome browser.

Hi Folks, new to the forum so please let me know if this request should go into another forum. I've flashed the m8s pro l and life is pretty darned good, huge thankyou !!! Noted one weird thing, every time I power the unit off and back on the language goes back to chinese ? I've worked out where the language selection is in the Android menu and I remove the chinese language. Reboot and its back. I went into twrp and its in english.. Havent read about anyone else with the issue but this wont go away :-)

Thankyou anyway, I've loaded Netflix and ABC i-view seperately and it works an absolute treat !!

Just disable the HDMI CEC auto language selection setting.

Hi Magendanz....I must be getting tired of trying to sort this all day :-) Where is that option ? I cant see it...I've looked in the Android menu and twrp....bugger.

OK, found it, sorry :-) Thankyou for helping.....we here in Australia really appreciate your work :-)

Settings->HDMI CEC->Auto change language

Anyone tell me what pins to short? got one of these coming for a friend

Thanks

Magendanz do you know if the mode for connecting to USB burn tool on these boxes is just "bootloader* mode?
as reboot to bootloader then connecting would make it a lot easier if so.

When I've done that in the past, I just got a black screen and i didn't try connecting the USB OTG cable because I'd always been told that you disconnect power for that. It would be worth trying as an experiment, though.
