Since I have updated my phone to Android 4.0.4 it has problem.
The phone freezes itself several times and remains the same for 2-3 minutes, then it reboots. ´Just today, it happened 3 times during one hour.
Before updating to this new Android, everything was working fine.
Solved! Go to Solution.
If the problem still remains I think you will have to get the phone checked by a repair center. Contact your local support team for more info.

Do one thing, format your SD card and reinstall ICS as follows

Backup everything as it will erase all data on phone (sms, contacts,apps)

Should I use both PCC and SUS?
Just one, use any
I used SUS. But the problem persists 
did you format your SD card as well ? before using SUS ?
I have some SMS and photos. If I format the SD, they will be lost.
Oh my, :smileymischief: 
You can send them all to pc, after sending the files to pc, format your SD card, after formatting send back all the stuff to the memory card
Copy all contents from memory card to pc and format it. later on send the stuff back
I see.
And could you tell me about taking backup from my SMS?
