I have one piece iphone that has frozen screen and does not respond to touch. Ive managed to get the screen working back again by erasing baseband. Now there is no signal, no baseband and i know i need to restore it again but the problem is that when i restore it to version 1.1.2, 1.1.3 or 1.1.4 the screen gets frozen again. When i restore it to 1.1.1 the screen still works but hangs. Can anyone tell me how to go ahead after erasing baseband?
