I have a iPhone 4 that has the 4.0 os I jb'd it with jailbreakme.com it worked ..... Problem is I used "reset all settings" afterward to remove things I didn't want now it's stuck in reset mode I've gone through pretty much all the steps on here to reset ...used tinyumbrella, Shift+reset ,etc. does not work I recieve error messages first 3002 now 3194. not sure what to if anything. I do not know if SHSH saved by Cydia and the ECID does not show up in Tinyumbrella. Please Help me!!! Do I need to Just bite the bullet and Reset/update or is there a way to get it back to the OS 4.0 that it was/is. I'm dumbfounded at this point that's why I'm asking 4 help....totally stuck.
