Hello, I just upgraded the Meizu MX4 Pro M462 International mine. But it turns out when downloading Firmware I downloaded wrong. I downloaded Chinese Firmware 4.2.8.2C. I should have downloaded Firmware International 4.2.8.2i. Well when I upgrade to Chinese ROM it turns out bootloop does not want to enter the system. When I want to repeat the upgrade with Firmware International it turns out when will enter the PIN there can only enter a single digit number only, and the command immediately states "Password Wrong". Though my PIN is a 6 digit number, but when typing the first number Message directly states "Password Wrong".

 

What should I do to solve this problem?
Please help me friends.
