Hey! I had the exact same problem on my first attempt. It's the custom firmware file you have. Find another one and you won't have any issues. Glad to hear the process (in general) worked for you. Just try another CF file and it will all be good.

Sure is! Just take it step by step and you'll have a jb 3.1 in no time!

Thanks for pointing that out by the way. If anyone ends up with no signal after they jailbreak their device on 3.1 then you need to try again with a different 3.1 custom firmware file.

I'd be lying if I said I knew haha. I only have access to iphone 3G's. I'm sure all you would have to do is to get your hands on a copy of a 3GS 3.1 custom firmware. I wouldn't know if it would change the baseband version that everyone is talking about though. I'm really not all that familiar with the 3GS when it comes to jailbreaking it. Someone else, who knows that device a litle more, might want to clarify that for you.

[500sd]

success for me!
just a heads up, you can't be starting from 3.0.1 even if you are jailbroken. you need to go back to official 3.0 than jailbreak then finally to 3.1 with the custom firmware.

done it !

but there still no Cydia inside. could it be possible because my 3G is on 3.1 (7C144) ( I looked this in my Iphone setting ), cause u mentioned that it need to be OFFICIAL 3.1. and yes, i did try other tutorial before.
how to get the official back again & redo this again...huh... I think I need to get my Iphone to 3.1 not 3.1 (7C144) right?

oh yes, btw, after all the 15 steps finish, i restore my last back up again, is that correct?

[creasy425]

i can confirm this method does work....just be careful which ipsw you use...i had to go thru 2 or 3 before i got one that worked completely

Before you start you need to have the following:
1. a copy of itunes 8.2 if you don't already have it installed. (download it here Itunes 8.2 Link
2. a copy of custom firmware 3.1 I cannot tell you how to acquire this.
3. a copy of Redsnow 0.8 (download it here Redsnow 0.8 Link
4. a copy of the OFFICIAL 3.0 firmware

*If you currently have your iphone jailbroken at the 3.0 level, put your phone in RECOVERY Mode (not DFU) and use steps 1,2,3,14 & 15

**If you currently have your iphone at an OFFICIAL 3.1 level, complete all of the steps.


Step 01: If you have Itunes 9 installed then uninstall it.

Step 02: Install Itunes 8.2

Step 03: Run Itunes 8.2

Step 04: if you get an "itunes library.itl" error then delete or move it from your itunes folder in "my music"

Step 05: Once you have iTunes 8.2 running, put your phone into DFU mode

Step 06: click "ok" when itunes tells you it detects your phone in recovery mode

Step 07: once your phone is in DFU mode, hold your shift key and click restore in itunes

Step 08: a window will open and you will now locate the official 3.0 firmware file and select it

Step 09: itunes will now install the official 3.0 firmware onto the phone

Step 10: at the end of this process you will likely get a error 1015 or something like that. ignore the error by clicking ok and your iphone should be showing the usb and itunes logo at this point.

Step 11: Now open up Redsnow 0.8

Step 12: Browse for the 3.0 official firmware and follow the directions that the software gives to jailbreak the iphone. during the jailbreak process for 3.0, you will notice that it seems to freeze at the "installing activation bundles" part. Don't worry, it is not frozen. Just give it a little while and it will finish.

Step 13: At this point your phone might have the USB and Itunes image back on it. This is fine. Open iTunes back up and you will probably be greeted with the "itunes detects your phone in recovery mode". Click OK.
DO NOT PUT THE IPHONE IN "DFU" MODE AT THIS POINT. Leave it in "Recovery Mode". Leave it as it is.

Step 14: Once again, shift click the itunes restore button and select the 3.1 custom firmware.

Step 15: THAT'S IT! Let it load the 3.1 custom firmware and you are set!

I have done this on 3 3G iPhones and can confirm that this process absolutely works. I hope this helps all of you that have been waiting on a windows version of redsnow th?at jailbreaks 3.1. This process may take more time but it will work.

Just to clarify a few steps in this process...

If you are on official 3.1 firmware, you have to downgrade to a jailbroken 3.0 firmware and have iTunes 8.2 installed in order to restore the CUSTOM 3.1 firmware. If you are already on a 3.0 jailbroken firmware then just make sure you have iTunes 8.2 installed because itunes 9 will give you error 16xx messages when you do a restore for CUSTOM 3.1 firmware.

I noticed that the majority of my steps look as though this is just to jailbreak to 3.0 SO i just wanted to make it clear that this is actually instructions to jailbreak 3.1

jailbroken,cydia installed but no service on 02 uk?

Ok this is what you need to do:

install iTunes 8.2 (use the link I provide)
restore to original apple 3.0 firmware (not 3.0.1 just 3.0 and nothing else)
install I redsnow 0.8 (use the link I provided)
jailbreak your 3.0 firmware with redsnow 0.8
now use I tunes 8.2 to restore to the custom 3.1 firmware you found

You have to have your device jailbroken at The 3.0 level before it will let you restore to custom 3.1 firmware. Only iTunes 8.2 (8.2.x.x will not work only 8.2)

Also, if cydia wasn't installed then you need to find another copy of custom 3.1 firmware to use.

Find another 3.1 custom firmware. You used a bad one. No big deal. Happened my first try too. Just find another and start over.

[ahffk1100]

[mreed93]

i cant figure out how to download itunes 8.2 it gives me an error message saying" itunes cannot be read because a newer version was created"

[lol_release]

guys I found the firmware but it's on rapid share and it's in three parts then I have to merge all three together.

I have the 3G 3.1

EDIT: oh yeah the most important part. I cannot download no more it's saying sign up for a paid membership so I only got done part 001

this is insane slow too!

[mniceguy81]

Thanks for all your help, i don't know if this is allowed but i did this and it was easy if you had custom firmware. For jailbreaking How to Jailbreak iPhone 3G/2G 3.1 Firmware on Windows and after to allow any carriers Unlock iPhone 3G 3.1 Firmware using ultrasn0w and then found out this on my own was to activate airplane mode and then diactivate it again. I hope this helps. and sorry if i stole your thread.
