Howto Resolve PIN Cicle after update

edited September 2020 in ZenFone Max Series
ZF Model: ZC554KL
Firmware/APP Version: WW__ZC554KL_15.2016.1902.507
Frequency of Occurrence: Each firmware update
Rooted: No
APP Name:

It's the second time that after the firmware update the phone ask me for the pin code and don't accept the right code. After reboot a coople times I noticed that the bootloader was unlocked... so I re-locked the bootloeader following these instructions:

After that, my pin was accepted.

Best regards,

    Hi Strong1983,

    Do you mean the PIN is not accepted after the firmware update?
    Do you have any screenshots or short video you can show us?
    Thank you :)
