Hi to everyone.

I have an iPhone 3g with this fw iPhone1,2_3.0_7A341_Restore. I want to downgrade it to iPhone1,2_2.2.1_5H11_Restore.

I am putting the phone in dfu mode and try to restore it from itunes (7.5.0.20) with shift restore after a while i get error in the image

I'm 99% sure you can't downgrade your iphone to this version,be careful or you'll damage your phone

Indeed, with its attempt you will permanently damage your iphone, as it is with your 3.0 will be better.

I also can not restore it to its original fw which is iPhone1,2_3.0_7A341_Restore it gives the same error.

3G with OS3 cannot be downgraded? I had 2.2.1 with wifi ok, now after update no wifi with OS3. Iphone is 16GB. I get similar errors while trying to downgrade. Any downgrade guide that has been tested ?
Thanks

You r using old version of itunes which not support 3G phones so download latest 8.2.023 for updating your iphone!

i have the same problem the error is microprogram is not compatible

recepoz · 07-10-2009, 18:22

I have installed the new version of itunes and i can restore it with the same fw. Actually my problem was the phone could not find any network and in the settings there is no such a menu like choosing or searching for carriers. Is there any solution for the network problem? without downgrading. Thanks for replies.

Try to use itunes 8.0.2.20 and restore your phone if it gives error just keep your phone plugged to your pc for 1 hour and again try to restore it will be done without any problem as far as i have seen the version 3.0 both for 3g and 2g are a bit buggy and the previous versions are much better than it i have personally downgraded my 2g and 3g to 2.2 successfully try and post result.
