Does this work for 3gs ?
-
like a charm...from 4.1 to 3.1.3
-
Thank you so much! Let me downgrade from 4.2.1 to 4.1 on my iPhone 3G allowing me to stop using shitty iTunes 10.x.x.x and now I can actually sync.Using Windows 7 x64 and I didn't have to run RecBoot in compatibility mode nor install LibUsb.
-
Can someone help me? I did everything but when got to the part to choose the file and restore, the message of error is different (it says that the firmware is not compatible) and is coming as soon as I select the file, doesn't take 10 min like it says in the tutorial. What should I do?
-
Thank you – this tutorial was very helpful! Worked perfectly!
-
I Just want to thank you for posting this tutorial. Worked Perfect on my device...thanks again.

so tired of how slow 4.x was. I hoped that apple would be clever enough to have a patch for the 3g to help with the speed. Nope! Now I don't feel like hurtling the phone across the room anymore. Thank you!!

I have iTunes 10 and couldn't follow the procedure for pointing to the 3.1.3 firmware. Looks like I would have to downgrade to iTunes 9.1 first, and I lost patience.Simply backed-up the phone, did a standard restore. I was surprised that the phone seemed to work at normal speed with version 4.2.1 firmware. Maybe the operating system generates junk over time, and doing a restore removes the junk that slows the phone down. I'm going to see how this goes before spending more time.Took me about an hour to restore and reload from the back-up I made before executing the restore.You might try this!

hi i'm new to the iphone and NOT AT ALL computer smart. I just got a iphone 2g 3.1.3(unlocked and i'm using a t-mobile sim) and wanted to get mms on it and it seems that all the hacks are only allowed by 3.1.2 if i were to downgrade to 3.1.2 would i lose my unlocked feature?
-
I get the same problem as this person, anyone able to help?---I cannot seem to get it to restore to 3.1.3. On a windows machine, I hold down shift and click restore, but it only wants to restore to 4.0. No option to restore back to 3.1.3. Has anyone else had this issue?---cheers,Pa.

How can i tell if I have a back up that is pre OS4. I need to downgrade ASAP
-
recboot link, show result not found??
-
Finnally Done the Downgrade, like this web creator! thank very much for help us.
-
Thanks !! It worked as you said, and now I got my phone back. It was soooo slow at 4.2, and 3.1.3 is back to normal speed.
-
This worked for me. I have a 3G that is locked to O2. I followed the instructions and have successfully rstored it from IOS 4.2.1 to 3.1.3. I didn't have the SHSH blobbs and didn't need them. I just used recboot 2.2 and the IOS that I downloaded from the web. Thank you.
-
Worked great!
-
Absolutely awesome! Phone is now working perfectly! Thanks so much!
-
I'm having the same problem :(
-
Guys, download the version of itunes you want to downgrade to, then old shift and click restore, then select the version you downloaded. then you can jailbreak shizzle
-
Oh holy crap. I just followed these instructions to the letter only to find RecBoot doesn't work with my version of OSX. I read all the insructions multiple times and didn't see anything about that part. So now what?? Am I screwed? I don't have an Intel Mac. I need help please! (Step by step help).
-
after restoring recboot didnt work and it restored itself on itunes and now i cannot get any contacts and pictures that i had before restoring how can i get them back????
-
After putting the phone thru the DFU mode, when I click on Restore button on iTunes, it does not pop up a window that I can navigate to the 3.1 firmware. Instead it automatically starts updating to 4 firmware.Can any one help?
-
Oh my gosh that's working ! And without shsh blobs files !Thank you very very very much guys you've helped me a lot !
-
