RS.1 - February 6 2021

As this device is quite locked down from the factory, the installation process is a bit long, but is easy once you get used to it.

You will need:

Unlock the bootloader first: https://androidforums.com/threads/how-to-unlock-the-bootloader-of-the-zte-avid-plus-z828.1324697/
  • Download the "Files for QFIL" ZIP file and extract it to the desktop
  • Boot into Factory Test Mode (FTM) by pressing VOL- and POWER
  • Connect your Avid Plus to a PC
  • Using ADB commands, type "adb reboot edl"
  • Open QFIL
  • Select "Flat Build"
  • Click on "Load XML" and select the Patch0.xml and Rawprogram0.xml files from the desktop.
  • For the Programmer, click "Browse" and select the firehose called prog_emmc_firehose_8909.mbn
  • Rename the downloaded recovery to recovery.img, and make sure it is in the same folder as the Patch0 and other QFIL files.
  • Click on download.
  • Once done, remove and put back the battery and boot to TWRP using VOL+ and POWER
