Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Working:
SD card access
Flashing
Brightness
Touch Screen
Everything else...

Not Working:

Installation
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:

• QFIL Flash Tool
• ADB Console (Platform Tools) https://developer.android.com/studio/releases/platform-tools
• "Files for QFIL" ZIP file (Check attachment)
• A PC

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

Note: Insert an SD Card at all times to save your TWRP settings
