Xperia Z3 D6633
I followed the very many tutorials (pick any on google) saying to flash (in fastboot) the file bootZ3monxtest01.img
fastboot flash boot bootZ3monxtest01.img
Now I have a bootloop around the sony logo.
No system, only recovery (TWRP) available
I can also reflash the whole system through Sony's Flashtool, but it kills the point, as a custom working recovery is required for later rooting
Obs. 1: Needless to say that the "usual" is to flash recovery onto recovery partition. I tried that. Nothing happened
Obs. 2: KingRoot rooting method worked, but I fail miserably to replace it by SuperSU
Obs. 3: It's my third attempt
:(
