3G on 4.1 Jailbreak method

**Kareen** · 11-03-2010, 06:49 PM

A friend of mine accidentally upgraded their iPhone 3G to 4.1 yesterday(Grrrrrrrrrrrrr!!!)-jailbreak gone. What is the best method to jailbreak this phone on this particular firmware?

Afaik Apple doesn't save the SHSH blobs for the iP3G so you should be able to down grade the iOS to any version you want. Sorry I don't know how to do this, but other posters will. Other wise try google.

You can jailbreak your 3g Iphone with Redsn0w 0.9.6b2 at 4.1

Hmmm.. Now I'm stuck in Recovery mode. Help?

**iYeow** · 11-03-2010, 07:56 PM

Have you started yet ?

Download tiny umbrella and put on your desktop, it is a great tool to use.
There is a feature , exit recovery mode.

**Kareen** · 11-03-2010, 08:03 PM

Ok. Used Tiny Umbrella to kick myself out of Recovery mode. Now, can I downgrade back to 3.1.3 using Tiny Umbrella, or should I just jailbreak it at 4.1?

**iYeow** · 11-03-2010, 08:07 PM

Are you at 4.1 or at 3.1.3 ?

**Kareen** · 11-03-2010, 08:09 PM

4.1. Boo.

**iYeow** · 11-03-2010, 08:34 PM

You just said you were back to 3.1.3, you confused me.
Alright, you need to download the 4.1 ipsw as well, run redsn0w 0.9.6b2 to jailbreak. See if that works. Just follow the instructions from Redsn0w 0.9.6b2.

So what is your progress now.

**Kareen** · 11-03-2010, 08:41 PM

Just ran Redsn0w 0.9.6b2 all the way through, twice. After the process, it says that it's complete, but I have no Cydia...

**iYeow** · 11-03-2010, 08:50 PM

Have you tried rebooting it ? If this doesn't work, I will show you another way, a much longer process though
Do the reboot and let me know.

**Kareen** · 11-03-2010, 08:51 PM

I've rebooted twice, now, but I'll do it again..

**iYeow** · 11-03-2010, 08:53 PM

Why don't you run Redsn0w one more time, you are using Redsn0w 0.9.6b2 right.

**Kareen** · 11-03-2010, 08:54 PM

No dice...I am and I'll run it again.

**iYeow** · 11-03-2010, 08:58 PM

Go to spotlight search and see if Cydia is there.

**Kareen** · 11-03-2010, 09:03 PM

Ran it again and the same thing happens at the end-black screen.

Restarted phone and did the spotlight search. Still no Cydia.

**iYeow** · 11-03-2010, 09:05 PM

Ok, now you have to restore to 4.1 again. I hope error 28 doesn't pop up, otherwise you will have to wait for battery to drain out.

**Kareen** · 11-03-2010, 09:06 PM

Restore 4.1 using Tiny Umbrella? Probably iTunes, actually. Does it matter that I'm doing this on a computer that he won't be syncing with?

**iYeow** · 11-03-2010, 09:14 PM

You don't need TU to restore, restore through Itunes, so your iphone has a fresh IOS 4.1

OR a shift + restore to 4.1 again.

**Kareen** · 11-03-2010, 09:40 PM

Restore complete. Redsn0w?
