SOMEONE PLEASE HELP EXPLAIN THIS TO ME:

So Apple sent me a refurb 3GS this past Tuesday, I activated the phone through iTunes to firmware 4.0...it has the old bootrom as the buildweek number is 22.

The description for sn0wbreeze says your 3gs has to be jailbroken ALREADY for this to install properly.

Since my phone isn't jailbroken right now...what are my options?

Do I have to wait for a jailbreak that will work for the phones with the new bootrom?

How can I jailbreak this thing?

3GS on 4.0 using Windows.

Thanks in advance everyone!

You cant right now.
You have to wait for a new jailbreak tool for 4.0
You will not be able to downgrade since you dont have shshs saved for this iphone thru cydia.

I'm having no luck with my 3GS either, I get error 1604. I had 3.1.2 jb on it until I upgraded to 4.0GM when it came out and now it seems only possible to get 4.0 jb (from a PC) if we are running an earlier jb os. When is Limera1n or a new Spirit coming along?

Come to think of it, what does spirit do differently to Blackra1n (apart from 3.1.3 support) that doesn't allow 4.0 jb via sn0wbreeze?

I realise this post implies that I ignored the old bootrom warning but I just thought I'd try it.

You just felt like waisting your time right :D
 
Great guide, but it didn't work for me. I have a 3GS, 4.0, and old bootrom. Any other tricks to get it to work?
 
I have a 3gs on 3.1.3 with a modem firmware of 04.26.08 I am trying to update to a jailbroken 4.0, I have a windows pc running vista. Every version of the 4.0 I find is a zip file, when I download it and click on it nothing happens. snowbreeze doesnt see the zip, and nothing unzips. What am i doing wrong? please email me dbrown430@yahoo.com

When you click to download it and click save then next window select "save as type" all files
And change the extension from .zip to .ipsw
That will do it.
 
EDIT: never mind -- the 2nd time, I ran ultrasn0w before restoring the backup from itunes -- all seems well now!

has anyone tried to restore their backup from itunes after installing the snowbreezed ipsw? Mine got stuck in an infinite loop (1/3 of the way through the apple logo boot). how are we supposed to retrieve all our backed up data if not from here?
 
I have an old bootrom on a spirit-ed 3GS 3.1.3. So can I trust this Snowbreeze as it's been deemed quite unreliable around here in the past?

Spirit is a userland jailbreak, which means it is applied after the OS starts. As such, it cannot modify the bootrom to patch out the signature check that prevents modified firmware (such as that made with sn0wbreeze or PwnageTool) from being installed on the phone. This is the reason Spirit cannot hacktivate the phone, as well.

I think the problem that Sn0wbreeze will work only on jailbroken devices and not with spirit! for example if you have 3gs on 3.1.2 then jailbreak it using blackra1n then jailbreak using Sn0wbreeze That's it

Yes, start the jailbreak :)
 
I have to question this part.

I have an MC model that I purchased on release day with the old bootrom.

I placed mine in DFU mode and then looked at the USB: Device Instance properties in Windows at confirmed it was using the old bootrom.

I also have an MC model number and the old bootrom... "iBoot-359.3"

That's the old one right?

I'm currently running 3.0.1 jb'd with redsn0w (I think). If I do this upgrade / JB with sn0wbreeze will I lose all of my apps, photos, etc from the phone?

Thanks,
 
I have a question about Step 7 with the activation part......

what exactly does it do? i think read somewhere if plan on using it on ATT...and click NO, your baseband is gonna be upgraded... is that right? will it still work on ATT after clicking YES?

thanks and confused
 
i just want to double check before i follow through with this, i checked my bootrom via DFU mode and it says its 359.3 but Sn0wbreeze says i cannot JB unless ive previously JB'd as shown in the attachment, is this a false warning?

under settings my model starts with MC

Again Model # HAS NOTHING TO DO WITH BOOT ROM dfu mode is the only way to check..


From the begining of the thread 1st page
You will be Easily able to Unlock your iPhone 3GS on any Baseband Including 05.13.04 / 05.12.01 Using Ultrasn0w

so I am going to say nope you can't jailbreak right now!

Im not interested in unlocking just jailbreaking. I know my bootrom is 359.3 so if I understand correctly I should be set to go.
