ok well i updated to 3.0 GM and for some reason my iphone become locked don't know why as it was working previously, and yellow snow was not installed. So i removed itunes 8.2 and installed itunes 8.1 i tried restoring to the original 2.2.1 firmware and the iphone came up with error 1604 now all the iphone shows is the usb cable to connect to itunes. And to make things worse it is not recognised on itunes in DFU mode please help.

a little help please xD

are you using the original sim that activated the iphone when it was purchased? I heard that it checks if its the proper sim upon activation after restore now. mine was on the "slide for emergency" screen for about 5 minutes last night and it said "connecting to itunes store" on itunes so i think it was checking the sim or somehting

[luksoccer]

thanks for quick reply yes original sim is in the iphone but now its not even recognised by itunes. it only shows the usb cable and itunes logo and it doesnt even get recognised it DFU mode. I'm really stressing here lol

hold down the home and power buttons for exactly 15 seconds and then let go and push the power for 2 seconds it ten should go to the emergency call screen and iTunes should pick it up

UPDATE: Now it is restored back to 3.0 but the screen is pink with the connect to itunes logo on it -.- but i can access emergency calls now and the phone still says its locked when it was not prior to upgrade of 3.0 (THANKS HEVEY)

oh and as said i was not using yellow snow

I read that you needed to have the sim card out of the iPhone when upgrading. A friend of mine upgraded and had his phone "Locked", then he restarted the phone and it worked fine.

Hiya.
Don't know If this will be of any help, but it worked for me, thanks to StealthBravo's advice. Be sure to use iTunes pre release 8.2 when upgrading to 3.0

also, TTY restoring to 2.2.1 using a version of iTunes that WILL recognise your iPhone. For me, the only version that worked was iTunes 8.0.0.35

also ensure that you have a non corrupted version of 3.0 GM

this worked for me in the end with no issues, but finding the solution took over 9 hours!! I think that was mostly because the official 8.2 iTunes messed my XP computer up and I had to run ChkDsk at least 3 times (taking 2 hours each time).

Hope this helps a bit.

i just installed 3.0 GM, i hadnt unlocked in the past, only jailbroken. All i did was update iTunes and install the 3.0 and there was no problem. All went cleanly

[luksoccer]

well ive installed 3.0 everything went smoothly but it still says that the iphone carrier ******** that my sim card is not supported , i am starting to feel alone ive had no iphone for more then 24 hours

I've had the same problem-Go back to 2.0.2 via quickpwn and you should be ok. I kept installing/uninstalling different itunes/firmwares, etc., to the point I was confusing which was which. You may have to use a different computer to do it.

i managed to downgrade to a custome 2.2 but then i could not make calls from my sim card or text etc. I really shouldnt of upgrade to 3.0 has cost me hours of sleep and so far a usless brick of an iphone.

and i have also tried on mac and windows

It might be something to do with the warning Apple sent to developers when they seeded 3.0GM?

This version of iPhone OS 3.0 should only be deployed on devices dedicated for iPhone OS 3.0 GM Seed software development. By installing iPhone OS 3.0 GM Seed software
on your Authorized Test Devices, these Devices are permanently “locked” into testing mode and cannot be restored to an earlier release of iPhone OS. Bear this in mind before installing the software.

[Shinner23]

No, I think that is BS.

[luksoccer]

any ideas ? anyone please lol

[coloradoxmfan]

Ok guys I figured it out. I was able to downgrade from 3.0 GM to 2.2.1 and jailbreak by doing the following, in this order:
1. Uninstall iTunes 8.2
2. Restart the computer
3. Download iTunes 8.1 (thanks to StealthBravo's website)
4. Install iTunes and run it
5. Plug the iPhone in to the computer
6. DFU mode - press and hold both the Home and Sleep buttons for exactly 10 seconds.
7. Release only the Sleep button after 10 secs, holding the Home button still.
8. At the iTunes recovery screen, shift+Ctrl the restore button and select your 2.2.1 ipsw file (google for this file)
8. Sit back and let iTunes do it's work.
9. Once restored, jailbreak.

Good luck!
