[ZTE Axon 7 Questions & Answers] Joker3139:
Hi there,

I had a problem after installing LOS 15.1, my TWRP could not mount /data anymore. I tried then to change the partition (first reformat, then to exFat4), however since then my data of my OS is corrupted and the phone only starts into recovery/TWRP.

In recovery however, it is stuck into the teamwin twrp splash screen... The phone still reacts to adb commands, but I cannot start it anymore except fastboot and into the explained recovery state... Anyone an idea how to get my phone running again?

(I tried already to install different versions of TWRP, did'nt help)

Here is my recovery.log after I start TWRP and it gets stuck:
