I was in serious problem now.
I tried Google device manager and locked my mobile using 10 letters password.
Now when I try to unlock my mobile, my mobile is accepting only 4 letters and saying wrong password, try again.
I tried changing the password again from Google device manager but I can not change the password. Google allows only one password and can not be changed.
I gave up trying all possible ways and decided to hardrest the mobile. But shockingly my mobile is asking for password even for hard reset but again it is accepting only 4 letters.
How can I use my mobile now ? It is useless. Is there any way to reset my mobile or unlock my device?
