hello every one i have another gs3 with another boot loop issue. so on first sight the phone looks good. it will turn on and show the screen saying "samsung galaxy sIII" but after that it goes black and 3 seconds later it vibrates then another 3 seconds and it vibrates again and then 3 more seconds and the boot screen is back displaying "samsung galaxy sIII". it will not boot in to recovery mode, however i can get to odin mode or download mode. it has never bin rooted, and it has stock rom, but i did try rooting it throu odin mode and it failed multiple times as well as the phone would display "unsupported format"? i have seen this before and it ended up being a power button and well i tried replacing that with no effect. i also noticed that when you do try booting the phone into recovery mode it will say "recoverybooting" in blue letters at the top left hand corner but just keeps boot looping, i need to recover the data on the phone since i was going to back it up but could not do it in time lmao!!!! any help or suggestions would be appreciated, i have bin at this for days now and my chances are looking dim some one said reinstal the stock rom throu odin mode i guess my only question is will reinstalling stock rom wipe my data or no?
