Hello,
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? :/


EDIT:

after i flash the 290 firmware via TWRP i get the message:
"E:Unable to mount '/data'"

yes i can via flashtool

there is no problem in flashing 534 with flashtool

was is creeping me out is that when i stuck on the sony logo i can't even go into the recovery so i have to flash everytime 534 root it install the recovery agauin and then i can try it another time...

i also tried it with phil recovery and "wipe to install a new rom" but even this didn't helped :/



when i didn't wiped anything after rooting 534 and install 290 over the rooted 534 i was able to go into the recovery and i saw "xperia" and the animation but it always rebooted at this point :/
