Howto Resolve PIN Cicle after update

Strong1983
Star I
ZF Model: ZC554KL
RAM: 3G
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: https://forum.xda-developers.com/zenfone-4-max/how-to/guide-how-to-unlock-bootloader-zc554kl-t367727... After that, my pin was accepted. Best regards, Carlos Chiriboga
