Only way to install latest TWRP is for @tenfar to sign the new TWRP , if not when you flash @Unjustified Dev latest TWRP will not boot at all, till you reflash @tenfar sign Recovery (which is actually @Unjustified Dev TWRP )
I'm so confused haha
So I've got the official root via zte for the European model.
Now to install twrp I need to use tenfar method which is a root anyway
So confusing why cant I just flash it through adb.
I did try and did do adb reboot bootloader but screen got stuck on zte logo and couldn't apply the fast boot command urgh.
