Hello there.
Sorry for my bad english.

I have a Huawei P10 Plus VKY-L09 (Android 7 B150).
I have the Bootloadercode and i had open the bootloader.
Now i tryd to flash TWRP.
But everytime i try backup my mobile i get the errorcode 255 :
"createTarFork_ERROR=255"

I had try version TWRP 3.1.0.0 and 3.0.2.2

What have i to do to my make TWRP working and backup my Phone.
I searched at internet for helpfull answers, but i didnt find answers.

I want to stay at Android 7 because i think Xposed and Xprivacy and AFwall work at Android 7

Thank you

Now i know, its because Twrp cant backup "Data".
This folder is encrypted.

There is no way to backup this folder.
at this time.

Deselect the folder and you can backup every other things.
