[ROM] Mecool M8S Pro LB TVStock Nexus ROM (Android TV 7.1)

[Guest]

In the spirit of the Pure Nexus Project, these TVStock Nexus ROMs deliver the pure Android TV experience using the Open GApps TVStock Package. 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 a la carte by the user as needed, just as I've done with the Stock and Nano variants.

Important Note: Please use my affiliate link so that GearBest continues to send me sample hardware: MECOOL M8S PRO L 4K TV Box

TVStock variant includes:

• Open GApps TVStock Package
• Open GApps Nano Package
• Google Chrome Browser (replaces stock/AOSP Browser)
• App Drawer 1.0 from CyanogenMod/LineageOS
• Terminal app from LineageOS
• TWRP Recovery 3.2.3-0 by TeamWin

Changelog (20190227):

• Fixed voice remote
• Latest build from Open GApps (20190227)

Changelog (20190217):

• Updated to latest M8S Pro LB OEM firmware (20181018.101400.V0213)
• Developer Options now visible by default in Settings.
• Updated to TWRP Recovery 3.2.3-0 using minimal OMNI twrp-8.1 branch and latest OEM kernel
• Latest build from Open GApps (20190209)

Changelog (20181111):

• Updated to latest M8S Pro LB OEM firmware (20180803.173707.V0213)
• Latest build from Open GApps (20181111)

Known Bugs:

• Google Cast service works from Chrome browser, but apparently requires Google license to work from Android apps.

Download:

• TVStock Variant: BURN PACKAGE (1.02GB IMG file), OTA UPDATE (568MB 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.

Magendanz, awesome ROM ...thanks, one of the best I tested. Just installed so just 1 quick questions ..

1. Is it possible to further customize your ROM - to add a preinstall folder and some apps?

Great work!!

Yes, if you add .apks to a /preinstall directory, they should be automatically installed during setup.

[joelba]

Thnx Magendanz !! will try for sure

[san_ic]

can someone please explain how to do this?

" With no reset switch, you can trigger USB detection by typing "reboot update" in a terminal window."

[Snakx]

you can test. connect power and push the menu button on the command many times

[san_ic]

sorry, did not understand. I have my m8s connected to my laptop usb to usb. what next?

[san_ic]

[wajeeh]

Great! Thanks dev highly appreciated.

Just need to know 1 thing.
can i flash it using flashify ? (currently on TV Stock LQ )

Sorry, I've never used flashify. I only use Amlogic's USB Burning Tool, TWRP and the Amlogic OTA updater, which you select from Settings->About->System Update.

I am using LB variant with LQ at the moment since this one got released 2 days back only.
anyways read the post in hurry back then as was in the office , It can be flashed via TWRP as mentioned in the OP so flashify should work fine too

i think proceed to a clean install with the .img file.

[wajeeh]

i think proceed to a clean install with the .img file.

Tried flashing using TWRP but it shows image larger than target system

I think that might be because I cleaned the system too.

Can anyone please upload the system backup of 3/32GB LB variant so i could recover my device.

There's a link to the original OEM burn package in the OP. You can always use Amlogic's USB Burning Tool to recover your box using that (although you might have to crack the case to short the reset pins...or the pins on the EMMC chip to enter Mask ROM Mode if you've messed up the bootloader).
