Jailbroken 3.1.2 3GS needs to be restored

[Adrenaline#IM]

So I have a 3GS with 3.1.2 jailbroken, and lately it has been crashing numerous times a day and has been a lot slower than usual. Is there anyway I can do a restore without being forced to upgrade to 3.1.3? I tried doing the Shift + Restore option, choosing the 3.1.2 firmware I downloaded, but it gives an error message that I will edit into the post as soon I get home. Are there any suggestions?

You can't do a shift+restore as it still validates with the Apple Servers.

When did you jailbreak your 3GS? Did you choose the option in Cydia "Make My Life Easier"?

I have the same problem here.
Got a 3GS with 3.1.2, JB with blackrain and it worked great.
Dummily enough I went to cydia and installed OpenSSH as well as iReboot (I think thats the name, just an app to reboot the phone).
Decided to restart it.
So usb/itunes screen came up, fired blackrain to make it boot and geohot's pic came up for a long time and nothing happened, then it rebooted by itself and went back into the usb/itunes screen.
Tried several times booting it through blackrain but same thing happends.

Tried restoring 3.1.2 from itunes but it doesnt let me, since it tries to verify it with apple, my SHSH on cydia are for 3.1.3 unfortunately.
Tried a custom 3.1.2 restore but it gets stuck on the preparing the iphone for restore screen, then it times out and throws an error.

I dont wanna let itunes upgrade it to 3.1.3.

Model: MC132
Baseband: 05.11.07
Bootloader: 6.4
Firmware: 3.1.2

Hope someone can help on this issue, I cant think of anything else
Had to put my sim back on a Windows mobile, but I am missing my iphone already

Original poster, does your 3G have a tethered jailbreak?

If you're on Windows, you can use sn0wbreeze to create a custom 3.1.3 upgraded firmware. If you're on the Mac, you can use PwnageTool to do te same thing.

Let me know. I was IN your situation. And successfully upgraded to 3.1.3 using sn0wbreeze, BUT I have a 3G with the old bootrom (not tethered jailbreak).

 

[LVCIFER]

Vbjr, your pretty screwed, however, if you have EVER saved your SHSH hashes on Cydia while you were using 3.1.2, they they're still there. They don't get deleted.

all you have to do is edit your hosts file to have iTunes point to Saurik's servers, and restore to that 3.1.2 file.

I have never done this with a MC model 3G. Any input from people who ave is appreciated greatly.

My SHSH files are stored with Cydia, and what exactly is a tethered jailbreak? I simply used blackra1n to do my jailbreak. I've had my 3GS since launch.

 

[LVCIFER]

So when you reboot your phone, you don't have to connect it to your computer and run blackra1n again?

 

[Adrenaline#IM]

Not at all.

Ok, go to:

iH8sn0w.com | Jailbreak your iPod touches and iPhones

Plug your iPhone into your computer via USB, download and run a program called "f0recast", and then post your results here. I'll guide you from there.

Dear LVCIFER,

Sounds a bit formal doesnt it? hehe

I have the 3.1.3 SHSH on the cydia server, but it doesnt have the 3.1.2

 

[Adrenaline#IM]

Here's my results. Thanks for all the help by the way.

Baseband: 05.11.07
Bootloader: 6.4
Model: MB717
Jailbreakable?: YES
Unlockable?: YES
Tethered?: NO

Ok, follow these directions/guided steps.

Jailbreak iPhone 3.1.3 with Sn0wbreeze | Redmond Pie

There are links at the bottom. One of those links is to download the official 3.1.3 firmware. If you download it, it may be a *.zip file. To avoide any problems, don't unzipped or extract. Simply rename it to a *.ipsw file instead of a *.zip file, and then direct sn0wbreeze to that file as your original firmware.

Also, you are on Windows, correct? Because if you're on a Mac, there is a different tool aloes PwnageTool. Sn0wbreeze is only for Windows.

 

[LVCIFER]

Once you're jailbroken, if you need to be unlocked, you'll need to use sn0w, also known as blacksn0w.

 

[Adrenaline#IM]

Yes I'm on Windows. No need for unlocking. But thanks a lot!

 

[LVCIFER]

No problem.

sn0wbreeze is the sh*t. I'm sure I'd say the same if I had to use PwnageTool, but I'm on Windows too...

 

[vbjr]

any pointers for me LVCIFER ?

 

[Adrenaline#IM]

Okay, so I did the sn0wbreeze method, but now my phone is just stuck on the startup logo and keeps rebooting. How can I stop this?

 

[LVCIFER]

Which startup logo? The Apple logo, or the custom boot logo (if you installed one)

 

[Adrenaline#IM]

Custom boot logo, I just did the simple method when I used sn0wbreeze

 

[LVCIFER]

Unfortunately, the fact that your on a tethered jailbreak limits things by a lot, unfortunately.

Especially since your only SHSH files are for 3.1.3.... that makes it almost impossible to downgrade/restore to a prior OS ("operating system").

I'm not sure what advice to give on this one, man. Sorry.
