I am new to this forum and this is my first post.
I purchased sony Speria M Dual in Dec 2013.
In the month of march 2014, Phone developed a bug. One morning, when i switched on the phone after charging, phone is showing following message " Type password to decrypt storage". However, i had not set any password.
Then i took this phone to service center in Mumbai. After 15-20 days, they informed me that phone's mother board is locked and they have to change the motherboard to correct this error. And they also informed that changing mother board does not fall under WARRANTY. So they refused to solve the problem.
Phone is not rooted, Bootloader is locked. Phone is running on stock firmware...i think 4.1.2
I have tried flashing the phone thru PC companion ...but it says "update unsuccessful".
I have tried flashtool also...but again not successful.
Phone is not entering into Recovery mode.
I request you to help in resolving this problem
