I just forgot to enable usb debugging and my phone crashed while flashing official cyanogenmod 12.1 (jalebi). Now it shows a 2 second yu icon and gets switched off while pressing power button. On pressing power+vol up it gives me a fastboot screen.
Flashing twrp recovery through cmd gives me message "oem is locked" inputing unlocking instructions give me message "oem unlock not allowed"
I dont know what to do now, help me please. I think there myst be coding to unlock oem or bootloader, help me anyone.
I got into same problem. Luckily my phone was in warranty period so got it fixed from SC. No other solution.
