HELP me unlock 3GS 05.13.04 PLEASE

[Skitsofrenic]

I'm trying to unlock my iPhone 3GS iOS 4.0 with 05.13.04 modem firmware. The Model is MC135LL.

I jailbroke the phone with Limera1n and installed UltraSn0w for unlocking, but for some reason, it wouldn't unlock. I'm trying to use T-Mobile on this phone. Please help! I don't know why the phone won't unlock..

Did I do something wrong? Was I not suppose to jailbreak using LimeRa1n?

I will give THANKS to anyone who helps.

Did you turn off 3G under network settings?

Yes I did.

Hmmm.. it should work. You can try rebooting or resetting network settings to see if that helps. Also if you have another tmobile sim try that and see if that works or not. Also make sure you are installing the latest version of ultrasnow in cydia. Check to see what version is installed.

I think the ultrasn0w version I downloaded was 1-1.1 or something like that

Ya thats the right version then. Try the other troubleshooting and see if that helps.

What other troubleshooting? I don't know any lol

The other stuff I said to do in my previous post, resetting network settings, trying a different sim etc.

Oh. I already tried them all but still no good. Any other ideas?

Try restoring (make sure you dont go to 4.1), setup the phone as new and try again.

How do I restore without upgrading? I think on iTunes, it says Restore to factory setting and Update. Is there a way to do it separately?

Do you know what SHSH you have?

[Skitsofrenic]

Do you know what SHSH you have?

I actually don't

[Simon]

Open cydia and see what SHSH it says you have at the top of the first page.

Now I'm on the screen where it tells me to connect the iPhone to iTunes. And on there is a writing that says:

Restore needed: iPhone cannot make or receive calls. Restore from iTunes.

Does this mean the phone won't work unless I restore it? I don't want to restore because iTunes makes me restore and upgrade at the same time. How can I restore this iPhone without upgrading??

Hmmm... That is not a good message to get. It could mean something is wrong hardware wise on the phone which could explain why you couldn't get signal after unlocking. Download tiny umbrella and run it with your phone connected. Press save SHSH and see what SHSH it is able to save and we can go from there.

Gotcha. I'll let you know what happens once I've tried it!
