i got a Sony Xperia Z1 C6903,
i bought it 5 Weeks ago, it got the Firmware 290
i Downgraded it to 534 and rooted it with "Root with Restore by Bin4ry"
then i flashed XZ Locked Dual Recovery and had no problems
i wiped everything like i should
and then i tried to install via TWRP the 290 Flashable.zip
after it i shut off my device (i didn't reboot just shut it off)
then i started to flash the striped 290 on the device
after this when i try to start the device all i see is SONY
and nothing else..
when i downgrade the firmware again to 534 and root it there are no problems... only when i try to flash to 290 it get stuck at the sony screen...
is there someone that could help me? :/
after i flash the 290 firmware via TWRP i get the message:
"E:Unable to mount '/data'"
