DESCRIPTION

prerequisite :

- have a system with adb and fastboot installed with correct path set

- have the usb debugging enabled

- run the command line and be in the same folder as the recovery.img file

instructions:

to test this recovery :

1:reboot in bootloader

type adb reboot bootloader

the phone will reboot and stay blocked on the nubia logo

2: test recovery before flashing  

type fastboot -i 0x19D2 boot recovery.img

this will reboot the phone after 4 or 5 seconds in the recovery, there you can test some menu…

To go back : advanced menu, reboot booloader

3: flash the recovery

type fastboot -i 0x19D2 flash recovery recovery.img

type fastboot -i 0x19D2 reboot

once phone is booted, type 

adb reboot recovery

I have only a Nubia Z7 mini, therefore I don't know if this recovery works on Z7 or Z7MAX …

you can try, but it will be at your own risk. Before flashing make sure that the testing phase is working

This recovery was found on a chinese forum

I tested the full process before posting here
