Hi saheermirza, Good day, Could you kindly tell me which firmware version are you currently on? (settings> system > about phone > software information> build number) Please also send me your serial number by PM for a check. (settings> system > about phone > status > serial number) Thank you.

Hi saheermirza, Good day. Sorry for my late reply. I would suggest you update the firmware to the latest WW-90.10.138.181. And reinstall the Bootloader Version V9.1.0.7 from Asus support page. Unlock Device App: Unlock boot loader(for Andriod P) https://www.asus.com/Phone/ZenFone-5Z-ZS620KL/HelpDesk_Download/ Have a try. Thank you.
