hi guys, i used jailbreakme on my 4.0.1 and was using it for 5-6 months. today i used clear settings option before selling this iphone and it went non responsive. on reset goes get stuck on apple logo. i tried reinstalling IOS using shift button and providing 4.0.1 rom but it fails after uncompressing. used recboot and miniumbrella to kick it out of restore mode but of no avail. I'm quite sure that i stored by SHSH files on cydia while jail breaking and now had put 18.104.22.168 gs.apple.com in host file but of no avail. can someone please help me in this regards. thanks in advance.
