Problem with SE k550i

[janx221]

I have phone SE k550i sometimes it turns on with no problems but sometimes when i try to turn on my phone the red light is blinking in the infrared place! And sometimes the phone fades to white screen and restarts and sometimes just stuck then i have to reinsert battery! Could anyone tell me whats the problem and is there any way to fix that problem?:confused:

could be a GDFS problem, try with different batteries first, if not nectified, 2nd step, make GDFS backup with xs and full flash with the latest of your same CID, if not solve, the D-ultimate unlocker is the last way i guess
