i have a 3GS with 4.1 jb with limera1n. i installed eclectic to check it out on my phone. decided that i dont want it, so i unselected in my winterboard and resprung. after phone loaded up, i removed the theme via cydia source. reboot the phone from sbsettings. then my phone froze at the lockscreen for couple mins, i had to hard reset by pressing home+power button. now it is stuck at the apple logo with a reboot loop. what could have caused this? is it possible to get into safe mode to disable winterboard if that is causing this reboot loop? what can i do to back up datas before doing a restore?
