[Medo22]

Hi guys I have a problem now when trying to flash custom recovery using adb fastboot this log always appear:
fastboot flash recovery recovery.img
sending 'recovery' (10704 KB)...
OKAY [ 0.341s]
writing 'recovery'...
#FAILED (remote: Command not allowed)
finished. total time: 0.345s

SO,I dialed *#*#7378423#*#* and I found that my bootloader is unlocked
then I USED sony flash tool and flashed official 4.4.2 then tried and nothing
WIPED EVERY THING then flashed official 5.1.1 and tried to flash recovery and nothing happened
so I ROOTED 5.1.1 by KINGOROOT and dowloaded flashify then when tried to flash recovery.img it gives me message (recovery partition not found) and so are the boot (boot partition not found)
what can I do help please !

I just did it .....same problem like you. I rename the recovery img to boot.img then flash it to boot.img . Then it boot up twrp.

But thus I will flash boot not recovery, I know it will work because I did that but the orginal problem isn't solved
