Help HELP !!! Boot Loop / Stock ROM

[hshokouhi]

Hi guys...

I flashed my GS2 with stock rom over 3 months ago, I didn't have any problem since 3weeks ago. I took out my phone from my pocket and realized the top bar is gone (but my phone was working without any problem) I restarted my phone and it went on a loop ! i tried to hard reset but for some reason I couldn't see the options and it was going to download mode (odin) automatically, I flashed it again but nothing happened.

finally took my phone to reapir centre and after 3 weeks they replaced the CPU and rewrote the IMEI number ! and didnt even tell me what was the reason for this ! (I couldn't find any technical person to ask!)

So, can anyone tell me what was the problem !? or has anyone had the same issue ? I reaally need to flash it agian to middleeast ROM to see Farsi language but I am a bit scared now !

the last time it happened to me was when i flashed an older firmware coming from a latest firmware

Did you send it back to repair centre ? My major problem wasn't boot looping ! that was just a beginning .. the major issue was losing a recovery menu, and without that menu I couldn't do anything. I am just curious to know whether there is any alternative way of getting access to root other than recovery menu or not, I am not an Android guru, just brave enough to follow the instruction
