the device was left unused for the last six months but when i tried to turn it on yesterday it turned on with an error message and the asus logo. The error message was error: invalid boot image. I downloaded the latest ROM version from asus offiicial site and tried to flash it through sd card and recovery mode but unfortunately it got stuck on 23% and eventually failed. Next time i tried to flash the room again but this tim it came with another error which is E: Can't mount/cache/recovery/last_log(invalid argument). What i did next is... i tried to flash it using adb sideload but then the error keeps on coming. When i tried the fastboot mode there was another error which is error: oem unlocking is not possible (i tried to unlock the oem because without that flashing is not possible from fastboot). The thing you should note is that :
1. debugger mode is not on
2. OEM lock is not on
3. I cant boot past the bootloop/error message which means i cant set usb debugging or oem unlock on
4. i have tried every other procdure from wipe cache/format data etc. what have i missed?
