My iphone 4 is stuck in recovery mode, connect to itunes I was trying to apply my stitched ipsw 5.1.1 to my iphone when I realized that I was doing it in recovery mode. I read the redsnow guide, I used redsnow to try and put it in dfu mode and now I get "missing keys .plist data for this build." Is there different steps that I can take to get my phone back? or have I really messed it up?

Since I have the stitched ipsw, can I upgrade to iOS 6 then downgrade?

Hi TonyM

try to create another stitched 5.1.1 ipsw.

Try this:

  • Create a NO_BB in redsn0w 0.9.14b2 (Extras/Custom IPSW/point to stock 5.1.1 ipsw)
  • Stitch the NO_BB 5.1.1 ipsw to 5.1.1 SHSH
  • Put iPhone to pwned DFU mode (redsn0w/Extras/Pwned DFU): Pwned DFU is important since you're restoring to a Custom Firmware.
  • Launch iTunes and do the shift+restore and point it to the stitched ipsw and restore

I have since upgrade to ios 6 since nothing was working. Now I trying to downgrade by following the above but I get an error 21 then I'm in recovery mode again and cann't use redsnow/recoveryfix to put back into dfu mode

21 is not pwned dfu error. Try pwnage tools on a Mac or ireb on windows for the pwned dfu part

I'm confused is error 21 a pwned dfu error? I have read in a different answers that it is but above that it's not. I still have a phone I can not downgrade. I'm using a windows 7 machine.

Download the latest redsn0w 0.9.15b2 (check FAQ for the link) and restore using redsn0w (redsn0w/extras/even more/restore).. You will be needing the original 5.1.1 ipsw and the 5.1.1 SHSH. Check FAQ for instructions

Use sn0wbreeze in simple mode.

(21 Oct '12, 23:16) spockers ♦♦ spockers's gravatar image

are you telling me to put my phone in simple mode or that is the command in sn0wbreeze?

(22 Oct '12, 15:35) jakiller jakiller's gravatar image

and will that put on 5.1.1 or ios 6?

(22 Oct '12, 15:38) jakiller jakiller's gravatar image

5.1.1 or less, depending on what ipsw you "feed" it at the beginning. Sn0wbreeze doesn't work with iOS 6 yet so that's not an option. Also, you will need shsh's (local or remote) for whatever version ipsw you use.

If you want to upgrade you have to manually specify the ipsw. What device to you have? If you have 6.x.x you HAVE to specify it. Is it is 6.0 i think its not necesary.

.plist data files are like xml files that iOS Core uses for reading info. For example an Facebook Info.plist file.

It stores information like where cache data is located and stuff like that. It changes in what kind of plist file is.

The Missing keys .plist its because you have to manually specify your device iOS (Extra,Select IPSW, and you have to select your device iOS .ipsw file)

That should fix the missing keys .plist error

If you got that error, im almost sure your device is with black screen. You have to press both buttons (home and lock) for 10 or more seconds so the device restart, then power it on. Wait for have the lock screen and then you enter DFU Mode.

For entering in PWN DFU Mode for make the stitched ipsw : Close Redsnow Re-open Redsnow Go to Extras>Select IPSW>Browse your iphone 5.1.1.ipsw file Then Go to Extras>Pwn DFU>Follow instructions for entering DFU Then you can apply yout stitched ipsw in iTunes.

Any question reply or send me an email

No, your data is not gone. You could retrieve it with third-party tool like GlobalShareware iFoneMate.
