xperia play hard reset fails

[kwdck]

Hello,

I got At&t sony xperia play r800at phone few months earlier. It was unlocked and i used it with my network provider with no problem. Unfortunately i have added a pattern lock and forgot the pattern. It was connected with my gmail account which i was using earlier and i do not remember the password either. So i have no way to remove the lock. I read that master reset will wipe the lock pattern and tried to do a master reset by going to the bootloader menu. But phone does not allow me to go there.

Please help me to solve my problem.

Based on this information, I can advise to remove a pattern lock you will need to use PC Companion to perform a software repair on the device. Please see the instructions below.

To repair the phone software

1.     Install PC Companion on a Windows PC from Support 

2.     In PC Companion, under Support Zone and click Start. 

3.     Under Phone Software Update, click Start.

4.     Click repair phone.

5.     Follow the on-screen instructions.
