iPhone Restore 5.1.1 from 5.1.1

[born2rule89]

hi guys,
i have 2 iphones , 4 and 4S. Both are running on 5.1.1
i just need to exchange them and be on 5.1.1
problem is that i want to exchange both of them.
so i tried restoring from redsnow with a 5.1.1 custom ipsw.
but it wont accept.
sometimes it gives error as 1600 or "your device is not build/eligible for this"
both are jailroken

please help
thanx

----------

when i opened tiny-umbrella it also said
"do not try restoring your device
httpd(PID:27) must be KILLED"


please help

you need to set your host to apple to fix the 1600 error

use redsn0w 09.15b3 to re-restore

go to Extras/Even more/Restore and folow instructions

you'll need the IPSW for both phones

For iPhone 4, if you saved 5.1.1 hash file, go to iClaified.com for restore tutorial.

For the 4S:

Read #1 & #2 on blog
Your 4S cannot be on factory fresh or OTA firmware, you must have used iTunes to arrive at 5.1.1
Also, the hash file must have been saved AFTER an iTunes restore to your 5.1.1 firmware.
Unless you can meet both requirements, you cannot restore.
If your 4S meets the requirements, iClarified.com has a restore tutorial.
