I purchased Xperia S a month back with default ROM GB, unfortunately i clicked ICS update and my phone got updated to ICS. But after update ICS have too many bugs like delay in opeining Dialer, wifi problem and the main Proximity sensor missed to get active in 2 calls out of 50 calls. This problem occurs twice in 50 calls. I had been following up with Sony service centre, according to that degrade to GB is now discontinued and cannot be happen, as these problems were not there in GB.

Please help me to resolve the issue to how revert the original GB rom

If you have unlocked your bootloader then you may void your warranty according to Sony's site

When your bootloader is unlocked PCC and SUS will detect modified software and fail to update.

Re-Locking your bootloader will allow PCC and SUS to updateyour phone

Thanks for posting and welcome to the forum!

Sounds like it would be wise to try performing a repair of your phone's software.

You can easily perform the interaction with our program Sony PC Companion, availalbe for download from the link below.

The Xperia S is not possible to "downgrade" to Android 2.3 after an update to Android 4.0 is performed I'm afraid.

What do you think about this forum? Let us know by doing this short survey.

Thanks Peter,

I tried thrice by repairing from the PC companion and from service centre also. The problem is still there.

Suggest me for following

1. My bootloader is unlocked, so can I install GB manually, without effecting warranty

2. After updation SI number doesnt matched the back panel and firmware

3. Any patches available for ICS
