satyanreddyg Welcome Slightly smiling Face

Unfortunately you can't get that swipe too close function on gingerbread as it's android specific. Only ICS + versions have it

Though you can install few homelaunchers or etc, that my allow you to do so

Ooops, they charging you 450 Rs ? ( = 10$ ) . That's too much. Why not checking with other service center ?

Achal_Agarwal Bootloder once unlocked is unlocked forever, warranty voids straigt away.

You won't regain any warranty after locking it.

May i know what you're connecting your device to ? ( Stock headphones ? )

satyanreddyg Downgrading option is available only for 2011 Xperia models

Achal_Agarwal if you're facing problems with your phone then i suggest you repair your phone's software

SUS ( Sony Update Service)  ... download and install it on pc and follow the on-screen instructions

Hi Nabeel

Thanx for immediate respone.

I did not connected any kind of headphones in my mobile. It keeps on flashing on my screen now & then. I have tried repairing my software from both PC companion & from the SEUS engine. The same link that you have mentioned.

However, since I dont wanna loose my warranty so, I havent tried degrading it. I have given my phone to the service center, & have even spoken to the Sony Regional Head Of INDIA.

I have a recorded conversation with him stating that he will either rectify the problem or replace my handset.

So, I am looking forward for a positive response from his as of now.

If still, he cannot help me out, then I will file a legal complaint against them, since my phone is under warranty.

But, thanks once again for immediate help.

greeky That error is fine or not depends upon the thing you want to do ?

Are you rooting your phone or flashing a full firmware ?

More details please Slightly smiling Face

Achal_Agarwal In that case it seems to be a hardware issue. They should help you though.

Letme know the progress Slightly smiling Face

mhossain98 That should not be a problem. It creates a problem for sim locked phones ( Locked to a network operator )

Do not worry Slightly smiling Face
