I have a 4s jailbroken untethered on 5.0.1 and have been trying to update and re-jailbreak with the new absinthe tool released yesterday but every time I try to do the 5.1.1 update on just my phone and it isn't working and every time I try to erase all settings and content through the settings app it just tries for ever till I have to force a restart. Now trying iTunes for restore and not having much luck. Any suggestions?
