Fixing 1604/160x iTunes Errors When Restoring

[Legendairy]

This is probably the only way to fix this problem, point is it worked for me.

Note: Before starting this tutorial please confirm you're iPod is in DFU, you can enter DFU by using a timer and holding down Home and Power together for 7 seconds, then let go of Power and continue holding Home for another 7 seconds.

Download this: http://www.2shared.com/file/4779652/9a7e51cd/iBoot.html

This zip should contain the following files:
iBSS211.dfu
iBoot221pwn.img3
libusb0.dll
iBSS221pwn.dfu
iRecovery.exe
pwn211ibss.txt <> This is just for offline purposes, i.e. you can't browse to this forum to copy & paste the arm7_go commands.

Extract iBoot.zip to your desktop, open cmd cd to the folder, if your XP you should be able to cd to it easily by typing:

cd desktop
cd iboot

irecovery -f ibss211.dfu

Now unplug and replug your iPod, the screen should turn white, if it doesn't please redo this tutorial from the start, make sure it's in DFU.

irecovery -s
arm7_stop
mw 0x9000000 0xe59f3014
mw 0x9000004 0xe3a02a02
mw 0x9000008 0xe1c320b0
mw 0x900000c 0xe3e02000
mw 0x9000010 0xe2833c9d
mw 0x9000014 0xe58326c0
mw 0x9000018 0xeafffffe
mw 0x900001c 0x2200f300
arm7_go
arm7_stop
/exit

irecovery -f ibss221pwn.dfu
irecovery -s
go
/exit

irecovery -s
setenv auto-boot true
saveenv
/exit

irecovery -f iboot221pwn.img3
irecovery -s
go
/exit

Your iPod should boot to home screen, then
Go to Setting > General > Reset > Erase All Content and Settings
Confirm you want to erase twice.

Now I strongly recommend you to leave you're iPod plugged in while erasing so the battery doesn't die.

When it's done open iTunes (with your iPod plugged in) and SHIFT+CLICK Restore to browse for the OFFICIAL IPSW.

Once you've done all that you're iPod shouldn't have anymore problems, and you can redo the whole jailbreak process.

Mods: Please sticky this, I think it'll stop many of the threads about this problem.

Are you sure you've cd'd to the directory?

if you're in xp and iboot folder is on your desktop type

cd desktop
cd iboot

before doing anything else.

[benn1230]

yes, all that is correct. i don't know what could be the problem. does it matter if it was in restore mode and then i put it in dfu mode?

i'm restoring it to 2.1.1. then i will try again.

hey this didnt work for me after i restored back to 2.2.1 i tried to restore to my custom firmware and i got the error 1604 AGAIN

Just curious: did you close iTunes and iTunesHelper.exe while doing all the pre-restore stuff...

Also... did you run patches before attempting to restore to the custom firmware?

I'm trying this right now! It's boring waiting for the data to be erased though

Will post results once I'm done.

Let me know how it works

And yes I know erasing is a long and boring process, I've had to do it 3 times know... 2/3 times were because iTunes messed up my iPod, turning all my music into Other :P. Last time was when I got this error.

Didn't work. Restoring to stock FW now. I'll wait for untethered.
