Can't install Widevine

[kshi]

You’re unlikely to find an Android 7.1 firmware specifically for that box, as it likely doesn’t even exist.

If you want to update the firmware you’re going to have to take a leap of faith and install one of the generic Android firmwares that install to a wide array of Generic S905X boxes, either ATVxperience or Aidan’s ROM:

Testers wanted: GXL, 1GB RAM devices, Amlogic-ng

If you have S905X SoC and want to try -ng builds, the ATV ROM its still available here: ATV4 S905X ROM Also, you could try this ROMs Aidan’s ROM. I used them only to install the bootloader and after that I manage to erase Android and write CE on emmc. Just the upgraded bootloader was necessary for me to run CE 19 on old Bqeel S905X box.

There is also this Android 7.1.2 ROM for a Tanix TX7 that seems to install to a number devices besides that model.

Will they work on your specific device? I couldn’t honestly say. Like I said, you’re going to have to take a leap of faith and experiment and be prepared for failure if you want to bring that S905x box up to being able to handle CE19.
