no twrp and no lock screen.
after the fastboot update stopped without finish I tried to restart in fastboot but the screen only turned off.
does not charge or reboot with any with any key combination.

any suggestions? :emoji_slight_frown:
thanks everyone in advance!
 
Hold volume down button and power. If it boots back to fastboot, flash again but make sure you have the full ROM, check the checksum if not sure. If you are using miflash, DO NOT FLASH AND LOCK or you will need the man from the post above.
