Thank you for your help. I've tried to relock the bootloader with SRK tool but it was unsuccessful because of root and I can't unroot.. HmmmmI had this problem last night with L09. Here is what I did:
If the phone gets stuck on 5% during the update then I've performed an install on the default recovery and repeated the steps above from number 3.
- Made sure the directory structure was correct on sdcard for the dload folder.
- Relocked bootloader
- Performed a factory reset
- Powered off phone and disconnected USB cable
- Held both up and down volume and turned phone on
- Phone updated
How did you unroot and relock your bootloader ?
