Hello.

Most likely this boot parition isn't compatible with your device. Please, try to use another combination firmware file.

You only have the 1 U7 firmware on your support please upload others.

1) Flash Combination U7
2) Use OctopusBox - reset FRP ADB
3) Factory reset ( Menu )
4) Flash Original rom U7 ONLY: Boot + sBoot + Recovery + System + Cache
5) Run ROM and duble Factor reset ( Menu )
6) Flash all file U7 Original ROM

note, the reset must be done on the firmware combinationnote, the reset must be done on the firmware combination
You also need to reverse the reset after flashing several files.
and only after that unlock will be removed and you can flash the full firmware
