    Same problem again.. Always unknown occure error,. Do you have updated unlocked bootloader apk? B'coz theres no unlocked bootloader apk in asus website model zenfone 3 max zc520tl.. Or I need to give my IMEI to unlock my device? This is my IMEI...

  • Hi 1435254balko 

    As I mentioned above, ZC520TL will no longer have any maintenance, and there is no official unlock tool on the website.

    Besides, I deleted the picture. Please be aware that sharing the personal information like SN or IMEI on the Internet is quite dangerous.
