Hello everyone! My friend forgot his iPad3 (ios 6.1,Jailbroken) 4-digit lockscreen passcode,or because he used another method to modify the passcode. Now I bypass the lockscreen 4-digit passcode,but when I connect wifi with completely correct password,but prompted me wrong password,wifi password can only be set to null to connectand. I restore the keypad dictionary must enter the password. I know the user mobile‘s password , and 5 characters long,but lockscreen only type 4 characters . I try to change the user mobile password , but terminal prompted: password must be at least 5 characters long. Is the user mobile =screen user (X window user,iPad general user)？How to change the password length? How can I do in addition to upgrade to 7.1?
