Hi there, I'm having a little trouble with my Galaxy S2, I'm a newbie to rooting and installing custom ROM's on my phone but have a rooted phone and wanted to try some different ROM's out, I knew it would be a good idea to make a backup of my EFS folder on my PC so that it wouldn't become corrupted with excess flashing, I used a program called EFS pro to do this and managed to save my EFS on PC fine, however now my phone has a number of problems, the home button no longer works, certain apps won't even open and my phone doesn't seem to be recognising my SIM. I tried to format the EFS folder and reinstall the one I had saved on my PC but it made no difference, does anyone know any ways to get around this problem, will I have to format my whole phone or is there a simple solution? Thanks for any help in advance
