How to restore without updating OS?

[jasonfj]

This morning I tried installing MyWi through Rock, and rebooted. Now my phone begins to boot showing the pineapple as usual, but after about 20 seconds shuts off. Tried many times with same result.

So I guess I need to restore to factory settings, then restore my back-up? My worry is that the downloaded restore file will be 3.1.3, which I will not be able to jailbreak. Will this be the case, and how can I work around it?

thanks

Well, it depends. What unit do you have?

3G on 3.1.1. I gave up and restored it. I'll just have to wait for the next jailbreak. :-[

On the 3G and 2G you can just download the proper firmware from any multitude of websites and hold SHIFT ( or Command if on a mac ) and press the restore button and it will let you browse for the firmware you downloaded.

You can downgrade to 3.1.2 if you like so that you can jailbreak.

On the 3G, can't he just use redsn0w to jailbreak stock 3.1.3?

 

[LVCIFER]

He just can't unlock, right?

 

[big9erfan]

You are correct.

I'm on a Mac. Can I just hold down shift to choose 3.1.2. Oh and I have a 3GS.

Thanks for any help.

No, you cannot.

Is there anything I can do to restore my phone? Cydia doesn't recognize 3/4ths of my extensions so I'm not able to update them or uninstall.

 

[big9erfan]

Do you have a tethered jailbreak?

 

[xpunksbeendeadx]

I have BlackRa1n.

 

[big9erfan]

I have BlackRa1n.

Ok, but that doesn't answer my question.

Lets try this another way:

- Is your iPhone currently jailbroken?
- What firmware version is it currently running?

 

[xpunksbeendeadx]

Oh sorry about that.

Yes it is currently jailbroken and running 3.1.2

Thanks again for the help.

 

[big9erfan]

Oh sorry about that.

Yes it is currently jailbroken and running 3.1.2

Thanks again for the help.

When you restart the phone, or it runs out of power, do you have to re-run blackra1n?

I have basically the same problem. My Iphone is acting weird and I need to restore but I don't want to update to 3.1.3. Could someone PM and give me a website that has instructions on how to do the custom firmware thing?

thanks

No I do not.

 

[big9erfan]

No I do not.

Do you need to unlock your phone to use on a different carrier?

 

[xpunksbeendeadx]

Nope. Making due with AT&T.

You can upgrade to 3.1.3 using sn0wbreeze and you will keep your jailbreak.
