Hi!
I just roll back my iPhone 2G from 3.0 to 2.2.1
Use PC Win (no any Apple software installed before), iTunes 8.1.0.52, Firmware 2.2.1 (iPhone1,1_2.2.1_5H11_Restore), bootloaders BL-39, BL-46, Microsoft.NET Framework 2.0 and QuickPwn225.
1 Put iphone into DFU mode
2 Connect to PC with iTunes
3 Shift+Restore and get firmware iPhone1,1_2.2.1_5H11_Restore
4 After restore shutdown iTunes
5 Run QuickPwn225 and follow instructions
6 Enjoy!

Good luck!

With love from Russia.

Hey guys, i tryed upgrading my 2g iphone to 3.0 using redsnow and it failed. no matter how many times i try it always fails, im currently trying to downgrade to 1.1.4 from 3.0 using the same steps RamPc suggested above.
when restoring to 1.1.4, at the part where itunes says it is “restoring iphone firmware” the process just stopped. i left it running overnight and it still hasnt made any progress.
any help?

Hi
i recently upgraded my iphone 3G to 3.0 final and also jailbroke it using Redsn0w but i cant use Cydia as it is always crashing. That means no cydia, no installous so no use of Jailbreaking.

Now i want to downgrade to 2.2 as it was working fine earlier, will it make any problem to me in future upgrades and Jailbreaks?

Pls reply

Any news on how to go about the above, i have tried many times, using itune 8.2, i m using iphone 3G, orignal using 2.2.1, after ugrading to 3.0, i lost my cydia, now i want to go back to the original 2.2.1, i have surf but none to be sucessful. Please help

Tried to upgrade the Iphone 2g to 3.0 but since there is no real jailbreak / unlock tool for it that works (redsn0w refused to reboot then when it said finished the iphone never rebooted) but i cant downgrade.

Mainly as i have narrowed it down to this:

In recovery mode (whilst phone is on, hold power and home, wait 2 seconds after it has turned off to release the power) i get a 1601 error when trying to restore

In DFU mode (whilst phone is off, hold power and home until the apple sign appears (10-12 seconds) then release the power and hold home until the itunes and cable sign appears on the iphone, i get a 20 error as soon as itunes has “extracted” the ipsw.

Any ideas?

Thanks

Here is my experience.
My iPhone was jailbroken 2 years ago. I did the upgrade to 3.0 and it worked fine but the battery wasn’t working properly so I decide (me dummie) to click “restore” from the iTunes. The iphone was, I’d say, virginized. The usb cable was on the iPhone screen.
I use Mac, I opened the “Pwnage Tool” choose the iPhone (i have a 2G) and follow the prompt instructions. It built a “IPSW” restoring file that I used later to recover from iTunes. I had to restart it in “recovery mode” while it was still on the Pwnage program. At the end you turn off Pwnage and on iTunes, HOLD THE OPTION KEY and click on “restore” it’ll ask you to choose the file you want to restore (see above).
First time something happen, came out with a error1600 but I did all the steps again and it worked fine.
My iPhone is back!
Thank you Pwnage!
Good luck!
