Thanks for this, it did help me, but I'm still having a problem.

Can I ask you, after completing this process, what .ipsw file did you use when jailbreaking with redsn0w? None of the 3 files I tried worked. They all cause redsn0w to hang on "Waiting for reboot," which I read on another forum is a result of not having the right .ipsw selected.

The files I tried were iPhone1,2_4.2.1_8C148_Restore.ipsw, iPhone1,2_4.2.1_8C148a_Restore.ipsw and the custom one you linked to, iPhone2,1_4.2.1_8C148a4.2.1Custom_Restore.ipsw. None of them made it past "waiting for reboot."

This process you described did allow me to exit Restore mode though, which I'd gotten stuck in, so thank you. But now my 3GS has the custom firmware but still isn't unlocked, as I wasn't able to do the final step, "rejailbreak again with redsnow". So still no Cydia on it.

Any ideas???

first of all if u jailbrked with the ipad firmware with redsnow....and took the risk in order to unlock..now ur iphone has the ipad firmware...and now ur stuck at recovery...and when u try to jailbreak again u get an error (the above picture posted by swoosh0217

here is what i did that helped me, after 2 days of searching.

first of all, (You have to restore to a 4.2.1 custom firmware made with pwnage tool)
since i am on windows operating system, i can't make the custom filmware since pwnage is a mac program.....so what i did is that i searched for one that was already made. the link is below

so 2 things we will need is, 1. the custom firmware made with pwnage, and 2. ireb

NOTE: PLEASE WHEN WE BEGIN, U WILL NEED TO PUT UR IPHONE IN DFU MODE (SCREEN SHOULD BE BLACK) AND NOT RECOVERY MODE.

In recovery mode itune won't let u restore because it will say u can't restore because of that ipad firmware.
In DFU mode: when u try to restore in itunes (with the custom firmware) u will also get an error number...ireb will fix this.

oky lets start, i just hope u understood what i wrote above.

here are the steps

first download the custom firmware 4.2.1 for 3gs made with pwnage tool in mac (thanks to the person that uploaded it

second. Download ireb http://hotfile.com/dl/82634505/856229a/iREB-4.0.x-4.1-RC2.zip.html

third. put ur iphone in dfu mode and open itunes and shift seletect the custom firmware u downloaded....u should get error like 1601..
if u get the error, open ireb and select iphone 3gs and let it do its thing and when its done now try to restore again with itunes (third step again) and error wont come up again.


then now rejailbreak again with redsnow.
thank you,

sorry for the late reply, i hope i understand ur qeustion well.

but, u only need the custom firmware to restore ur iphone in itunes with the ireb program.

if u want to jailbreak with redsnow again, don't use the custom firmware, but use the apple offical 4.2.1 firmware.ipsw for iphone 3gs

i hope this helps u. thank you
