CoreELEC eMMC installer for Ugoos AM9

dangerouslaser · 15 May 2026 11:20

DO NOT USE THIS METHOD IF WANT TO ACCESS ANDROID ON THE DEVICE.

IF THE EMMC INSTALL FAILS YOU CAN STILL ALWAYS BOOT FROM SD-CARD BUT YOU WILL NOT BE ABLE TO ACCESS ANDROID WITHOUT RE-FLASHING THE DEVICE WITH UGOOS’S TOOLS (WINDOWS ONLY).

I have CE installed to the EMMC on the AM9 pro. the user interface is noticeably more responsive with a large library and artwork-heavy skin (arctic fuse 3).

Just note that this is destructive - you will not be able to boot into Android after doing this. You will need to use ugoos’s flash too to restore the device back to Android.

yeah this script is a bit clunky, I just had claude spit it out after I finished getting everything installed and verified functionality. just tightened up those two call-outs. always open to feedback.

again want to re-iterate that this is destructive and experimental

You completely remove Android and also they way to be able to restore everything.
This might work for your device with this firmware. But any other device or a newer firmware will prevent booting or media playback again.

This is why the tool ceemmc becomes to be obsolete.
