So I tried to restart my jailbroken iPhone 4.2.1 and now it's stuck on the boot logo. I tried restarting it again and again.. Please help? I used greenpois0n to jailbreak it in February.

You've installed some cydia tweak that's preventing it from booting is my guess. You'll probably have to restore to fix it, unless you can get into the filesystem and remove the offending tweak.

let's restore and re-jailbreak. as simple as that.

if you want to preserve your baseband follow this:

1) (Win) go to and download sn0wbreeze 2.6 (Mac) go to and get pwnagetool

2)download your IPSW -,1_4.3.2_8H7_Restore.ipsw

3) open sn0wbreeze (win) or Pwnagetool (mac), browse for the IPSW you just downloaded

we do all in Simple Mode, but if you want to hactivate/enable mt gestures etc- use Expert Mode

4) follow the instructions in sn0wbreeze/pwnagetool to restore via pwned DFU.

if you don't want to preserve your baseband follow this:

1)download your IPSW -,1_4.3.2_8H7_Restore.ipsw

2) connect your iPhone to iTunes, hold (win) shift (mac) option and click on restore. (browse for the IPSW you downloaded)

3)when you're successfully restored, get redsn0w from

4) open redsn0w, browse for the IPSW you just downloaded.

5)tick on "Install Cydia",follow redsn0w later.

NOTE: in all this process, your device is connected to your computer.
