Flashing TWRP 3.0.2-0
Specific Root for Pixi 4 Plus Power (5023)
"For the Pixi 4 Plus Power (5023), you cannot flash the recovery using the commands below, you have to first boot the recovery with fastboot boot twrp-3.0.3-0-5023.img
. Then make a backup of ALL your partitions
then you root with this SuperSU
. After rooting, reboot to the system and install a root explorer and go to the system partition and remove this file "recovery-from-boot.p". Copy the TWRP recovery (see attached post) to your sdcard/external, install flashify and flash the twrp-3.0.3-0-5023.img to get permanent root. "
I need to ask how to make full backup of ALL partitions? When I searched XDA I found that it is possible only on rooted device
