iPhone IPhone 4 stuck in recovery mode

Have you tried tiny umbrella to kick it out?

Why a custom IPSW, those are for preserving baseband only. ?
What baseband is on your phone.
Also try Redsn0w Recovery fix (or TinyUmbrella which always has worked for me).

Once you get it out of recovery, go to iClarified.com and follow a tutorial.

Are you sure you were actually in DFU mode? You should not see the iTunes logo on your phone if you are properly in DFU mode.

Open RedSn0w and follow the steps to get into Pwnd DFU mode, then CAREFULLY follow the steps - you should see just a black screen and RedSn0w should confirm that you're in Pwnd DFU.

After that, you can Shift+Restore in iTunes to install your custom iPSW. If that fails, you may try to download another 5.1.1 firmware (perhaps from a different source), and cook a new custom iPSW.

from the iphone wiki:
Error 1604
Device was not pwned (signature checks were not blocked). Custom firmware can't be restored. Can also happen when there's a problem with the IPSW.

Try again in pwnd-DFU mode using redsn0w

I'm not in DFU mode guys! When connected with redsn0w it recognizes the mode as recovery mode. When i try recovery fix in redsn0w it ends up with an error "DFU mode failed-You have ended up in recovery mode instead of DFU mode."

someone please help!!

Click to expand...

been there before...
system files are corrupt.. iPhone cannot launch because some needed files aren't even there or damaged
my solution was Restoring in iTunes

I'm going to suggest that you seek out somebody with more knowledge then yourself on jailbreak/unlocking by that I mean a friend or maybe somebody on craigslist. you have to do things a certain way or else you will loose the preserved baseband also have you tried contacting the carrier to see if they will unlock it. I just think your a little out of your knowledge area here unless you to things correctly your going to mess up big. Yes we can talk you though but we miss a step or you don't fallow a step you are SOL. Also do not update though Itunes as suggested you will loose your baseband. you can also try Ireb and Snowbreeze both for PC only to kick it out.

Having the exam same problem!

Guys,

I just landed myself in precisely the exam same situation.

Locked iPhone 4 with 5.0.1 trying to upgrade to 5.1.1 but got stock while iTunes was upgrading and landed in recovery mode. Tiny Umbrella, iReb, Redsn0w.. all have failed to get it out of the recovery mode. Unless it gets out of the recovery mode, I can't get in the DFU.

Read plenty of blogs.. trying my luck here as well.

Any help would be much much appreciated!

Thanks,
H

Here's what I did

I had the exact same problem after trying to update while saving my BB. I got that same error message that you did. Before you even press next on the screen start doing the process to go into dfu. You will not receive the error message and redsn0w will recognize your in dfu and continue the process from there!

If your phone is out of contract then AT&T will unlock it for free assuming that's your carrier. Also there are tons of cheap imei unlockers out there. There are threads on here suggesting good ones. Also eBay is good because of the feedback available. I got mine done for $13 and it's gotten even cheaper. AT&T again...
