iPhone 3GS iOS4 JB Problems?

pratstercs · Jul 4, 2010

Hi,
I have an iPhone 3GS New BootROM currently running iOS 4.0. I have (or had) SHSH blobs on the Cydia server for both 3.1.2 and 3.1.3.
I have upgraded to stock iOS 4.0, and now cannot restore to 3.1.2 or custom (Jailbroken) 4.0 ipsws (4.0 created in sn0wbreeze), giving 1600, 3014, 1604 and 3194 errors.
I need the phone jailbroken, preferably on iOS 4.0. It does not need to be unlocked, I am in the UK on O2.
Any help would be much appreciated?
Thanks

Did you update your host files to redirect iTunes to cydia instead of apple?

Yes, has been in place for months.
Check: 74.208.10.249 gs.apple.com

After you restore and get the errors, use TinyUmbrella to kick the iphone out of recovery mode.

I have no problems getting in/out of recovery or DFU modes, the problem is that i'm stuck on vanilla iOS4 and can't restore to JB'd iOS4 or below.

how do I check my 3GS with oldbootrom or newbootrom? Im learning about JB+UL my 3gs

I thought new bootrom 3GS's were unable to be jailbroken on iOS4 at this time...?

iPhone 3GS

Summary: Currently, PwnageTool only works on previously jailbroken 3GS devices with the old bootrom.

If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.01

Not possible to downgrade with the new bootrom. Doesn't matter if you have the SHSH blobs backed up or not, those only matter for the old bootrom 3GS's.

Old or new bootrom 3GS can be downgraded using Saurik's method if hashes are saved.

Thats false.
You can downgrade any bootrom old or new if you have SHSH's saved for the particular built.
What you cant do with a new bootrom 3GS is update to custom pwnage 4.0 IPSW
Only old bootroms you can since the bootrom is pwned and the new bootrom is not thats why its a tethered JB.
I think thats where the confusion came on your part.

In the same boat mate. I have a 3GS on iOS 4 with O2 as well. Will be nice if this gets figured out.

Sorry for the rookie mistake, thanks guys for clearing that up. Hopefully a 4.0 JB for the new bootroms are coming out soon 🙂

I downgraded my NEW bootrom iPhone 3GS from 4.0 Final to the official 3.1.3 earlier today, so obviously it does work.

Can't we use someone else's SHSH blobs? I have a friend's 3GS that's absolutely stock running iOS4 on the new bootrom. Never been jailbroken using anything ...

Please assist ...

They are unique to each phone. You cannot downgrade without "your" SHSH saved.

According to the site above, you can. Testing pending however, will report with results.

You can't JB a new bootrom 3GS with pwnage with 4.0 IPSW yet.
That site above claims they could release something out but only if you have SHSH's saved for 3.1.2

Doesn't every downgrade or JB for iPhone 3GS require 3.1.2/3.1.3 SHSH blobs?

Downgrade yes. Not every jb though. There is userland jb's like spirit that don't require shshs and bootrom doesn't matter.

urgh! so complicated! these hacks are so un-apple-like!

I meant for iOS4 on 3GS *facepalm*.

Because they aren't made by Apple and Apple are trying to make it as difficult as possible for people to jailbreak

There should be a userland spirit type of JB for 4.0 that will work for all 3G, 3GS and even iPhone 4's.
Stay tuned and be patient.
