Downgrade 2.2 to 2.1

[mgreen]

It is possible downgrade an iPhone 2.2 to 2.1. I make a big mistake and make the updated in my iPhone first generations.

[ZIGE]

did the same thing on my 3g and it looks like we're screwed until the dev boys find a solution.. fingers crossed!

[cricketlang]

there was a HUGE post NOT to upgrade guys. cmon....to get back to 2.1 use the guide below to get back to a jailbroken 2.1 or just download the firmware.... do a "shift" restore in itunes...locate the 2.1 file and then restore. please pay attention before you just do things

lol i was awaiting these threads...wow, sorry guys plus of you have a 3G your possibilities for a unlock (not jailbreak) are really at risk! but hopefully it will ne soon

[cricketlang]

^^^^for real. i knew they would be here and im posting the same thing in every one. people really agitate me with this jailbreak thing. there are TONS of posts saying not to jailbreak and people are still doing it.

[pokefan]

bahahah n00bs! Oh, sorry I guess I fall in that cat. too...

But I listened!

(sorry, couldn't resist)

[cricketlang]

at least you listened. thats the important part. the dev team will handle the jailbreak and ALL they are asking for is our patience. is that so much to ask?

[bruinsrme]

I didn't download 2.2 but did download 8.0.2.
Now I can't update apps. Hopes its an issue on their end.
But cmon the warnings for early adoption of 2.2 have been abundant

[Ad1tya]

2G guys can easily downgrade to 2.1 using iTunes 8.0..

3G guys are stuck and stupid because there was a Baseband update. Good luck trying to Unlock in the future..

[cricketlang]

^^^^ for real. there was a reason why there were so many warnings. i didnt know about the baseband update though. good to know. thanks man

[rx7turbo287]

come on ppl, do not update itune or phone yet, until there's fix for it. how many firmware we be thu this??? yeah google street is going to be pretty cool, looking forward to that one, but most of all i wanting for is soft unlock for 3g, ready to take out turbo sim!! couse too much problem with edge. if u update it, i think, not sure, is make sure u are on older itune 8, not the new one, uninstall it, uninstall apple mobile.... erase the itune folder. after that reinstall the older itune 8. then force phone into dfu mode, then shift restore phone 2.1. i think it should work, for 3g or 2g, but the baseband part for 3g its going to be a problem.

you get the same result with out using his metherd.just use itunes and restore to 2.1 it says error but dont worry just reset the phone use quick pwn and your 3g will come back BUT dont use cydia your 3g will crash i know its not perfect but you can use your phone until quick pwn is updated

[MrMel]

except that just downgrading the firmware will still let the 2.2 baseband be installed, and that if you use hardware unlock method, isnt gonna make your phone work.

But there has been no confirmation on that link I posted, so my guess is that its fake.

Hi, sorry for my mistake, I bought an used iphone, the last owner reset the phone and I need to activated, i have no idea what firmware it have, i try QuickPwn, but after i choose the Firmware in step seven the blue arrow still greyout and i can't continue.

actually this information was posted before anyone even knew about the baseband update SOOOO its not complete crap. also watch your mouth before you get nailed by mods/admins as well as an infraction for disrespecting other members here. i knew about the baseband update as soon as the dev team posted it and i corrected my posts after that. and also my posts are not complete bull for the 2g users the only one that wouldnt work perse would be the 3g one because of the baseband update. so maybe YOU need to know what your talking about before YOU post disrespectful things about other users.

Any1 tried that? one of friends of mine put effort to do this.but,the baseband is still the latest one which comes up with FW 2.2.Although,the FW version has been downgraded to 2.1 after using this method.

is it a 2g or 3g, if it is a 2g, just restore the phone with itune then quickpwn it, if it 3g, need to find out why it is not activated, most likely he restore it, need to find out from him what he restore firmware, 2.1 or 2.2, there be a problem with 2.2, since it'll update the baseband. iphone dev warn not to do it, it'll mess up software unlock in the future. now i really don't know why, at some point we would have to go 2.2, but who knows.
