[Xperia Z5 Q&A, Help & Troubleshooting] Sedhadi:
Hi

A few hours ago, my phone (E6633 - 7.1.1) restarted by itself and got stuck in boot (SONY logo appears, red LED turns on, it restarts again and the same happens over and over)

My phone was rooted with Magisk and had TWRP.

I tried lots of times and finally managed to enter TWRP, but neither wiping nor restoring was successful. (The error I faced was sth like this: twrp failed to mount '/system' - and then the phone restarted again)

I flashed my phone and here's the logs:

The first time I flashed, It restarted after a long boot animation and the same bootloop...

I flashed again and bootloop happened with no long boot animation.

Any idea how to get my phone fixed? Is it really dead?!
