[ROM] Mecool KM9 TVStock Nexus ROM (Android TV 8.1)

[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 KM9 Android 8.1 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 3.2.3-1 by TeamWin

Changelog (20190117):

• Based on latest OEM firmware (OPM1.171019.011 V0828.20181205)
• Latest build from Open GApps (20190117)

Changelog (20190106):

• Initial release
• Based on latest OEM firmware (OPM1.171019.011 V0828.20181122)
• Latest build from Open GApps (20181229)

Known Bugs:

• Android TV Remote Control service will pair, but keeps dropping the connection.
• Google Cast Receiver broadcasts, but will not connect.

Download:

• TVStock Variant: BURN PACKAGE (1.69GB IMG file), OTA UPDATE (966MB ZIP file)
• Flash burn package with Amlogic USB Burning Tool v2.1.7 or BootcardMaker v2.0.0.2

Notes:

• The local Terminal app shows after being enabled in Settings->Developer Options.
• To make Developer Options visible, click 7 times on Settings->About->Build. To make it visible in the legacy Settings app, click More Settings->System->About Device->Build Number.
• Other devices based on the Amlogic u211 reference board may be compatible with this ROM, but there's currently no support for different wireless chipsets or IR remotes.
• The updater is signed, and so can be installed in the Update app (Settings->About->System Update), 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. The reset switch on the KM9 is through the AV port.
• Flash ROMs at your own risk and always remember to back up your data first. The burn package includes a factory reset.

What is the benefits of installing this ROM over the standard ROM?
My box freezes while streaming live TV. That sucks. Will this rom fix the problem?

This custom ROM adds support for some popular game controllers, uses the Lineage App Drawer (for non-ATV apps), exposes More Settings (non-ATV settings), bumps up the UI resolution, and strips more of the non-essential OEM apps out. Frankly, now that VideoStrong has switched over to Android TV and the TV Home Launcher, the differences aren't all that significant. It's really a matter of taste.

Streaming bugs probably won't be corrected with this custom ROM, as I didn't do any kernel work or update codecs/drivers.

Thank you so much. Thanx for the work. Been looking out for better firmware for this box. My H96 Stick was good to me , but this box has better specs. I will have a look out for more firmware.
if I flash this , where can I find the original firmware if I want to go back?
Also , is the flashing the same as other boxes?
Hold the reset button ( in the AV port) and connect via USB to USB? Do we use the USB 2.0 or 3.0 port?
Thanx mate !

Latest OEM firmware is linked in the change log. The USB OTG port is the USB 2.0 (non-blue) port on this device.

If anyone's feeling adventurous and contemplating flashing this on a H96 Max X2, don't do it, it will get stuck on the NEXUS logo flashing every few seconds, it won't boot.

I agree with Mr. Aeolous, this update DOES fix the issue with live TV streams not playing. If you can mod it to the Android TV OS version, that would make it very useful. Still, it does NOT support any of the HD audio codecs or video framerate switching.

Will do. I'm also trying to include drivers for SMBv3 support, which is now the default in Kodi. Hoping that I can steal it from the latest nVidia ShieldTV firmware release.

Thank you for this great Rom.

The only problem I have is that I cannot pair my Bluetooth remote. Any suggestions? There is no first blue screen to connect remote... and in the bluetooth settings "cannot pair"...
Thank you in advance.

Thanks, Magendanz for this updated version. I downloaded this version you just posted, but it appears to be the stock firmware. The version says 20181205 test keys. It is the stock Android TV OS version.........

Is this correct??

Edit. I tested your zip version that has to be installed using a microSD card and it is the same 1205 version of Android 8.1. To be noted, the microSD card has to be inserted upside down. Also, when I used the update app it went to a version of TWRP called OpenRecoveryScript to do the install/update.

Yes, it's a custom ROM based on the OEM 1205 firmware release. However, that OEM release was not Android TV. It had the ugly old VS launcher and the mobile Google Play Store.

The OpenRecoveryScript is just an open standard for running scripts in TWRP (or even OEM stock recovery, for that matter) when you revert to factory defaults from the OS.
