Hello, I have used threads here 6months ago to install stock firmware + root. I decided to flash this rom today http://forum.xda-developers.com/z3/general/6-0-1-23-5-0-570-prerooted-recovery-t3362790
After rebooting all i get is the Sony logo, and nothing. Have to press all 3 buttons (power,volUP,volDOWN) for it to turn off...
Battery screen wont show when plugged into power/usb
Have tried Flashtool and the Sony Companion, they dont work. All i get is Sony logo after flashing/repairing.
Update: Flashed stock successful
