hi!! i am just a new user of iphone 3g with a firmware 4.2.1.. i decided to downgrade it to 3.1.3 since i have heard that that firmware is faster.. But unfortunately, when i turn my iphone on, the msg slice for emergency calls appears.. so i am now not able to use my iphone.. could you help me with this issue?
-
thanks mate worked like charm, I can use my iphone 3g again after the s**t upgrade to ios 4 THANK YOU.Apple you're a rip-off why do you let people upgrade their 3G to IOS 4 since it's not for thesedevices ?
-
so, i want to fully understand this... if you had a jailbroken 3.1.3 phone you can downgrade from os4 back to 3.1.3? and, if you go through the restore process and get back to 3.1.3, what about all phone info like contacts, texts, apps etc...??

You just have to insert a valid sim and connect it thru itune. your sim must be the original network like at&t and tmobile. gudluck men..

It seems to do everything perfectly but when it gets to updating the iPhone and when the error message shows it shuts the iPhone off and I attempt to open RecBoot and I still click Exit Recovery Mode and it just stays on that? Is there any reason why it just stops dead at this point ?:SThanks !

Hi Leela, i'm ready to downgrade my iPhone 3G to iOS 3.1.3 but i'm afraid if something like that go wrong.i downloaded iOS 3.1.3, RecBoot 1.3 & libusb-win32-bin-1.2.5.0.is that ok? did you find out how to resolve a problem like that?
-
HELP!! when i download the restore file it's saving as a zip drive and not as a .ipswWhen i hold shift and press "restore" it doesn't find the file i downloaded bc it won't save as .ipsw it only saves as .zipam i doing something wrong??
-
I tried it and had the same experience - emergency only dial screen. Was working fine before.
-
i dont get what the last program is for... that libsusb
-
Worked great for me. Thank you!

It keeps iTunes from showing your phone as being in recovery mode so that you can set it up as a new phone or restore from a pre-iOS4 backup.

Oops. Never mind - I see you're on Windows. My comment was for the Mac program. Carry on...
