Isn’t it great that The Dev Team warned us not to update. If you updated your iPhone 3G/3GS and you need the unlock your a total idiot haven’t you learned your lesson back in SeptemberNovember 2009 (Hehe, good times, good times…)

This time if you are really stupid and updated it then your a complete moron (I’m saying that in a non-offensive way but seriously) Reply

Justin, Re: “If you updated your iPhone 3G/3GS and you need the unlock your a total idiot” and “This time if you are really stupid and updated it then your a complete moron (I’m saying that in a non-offensive way but seriously)” First of all, it’s “you’re”, not “your”. Second of all, you can can’t call someone a complete moron in a non-offensive way, you mor….nevermind.

Hi, just a question – my friend owns an iphone 3GS – 3.1.3 firmware (i am not sure he did an update, or did he bought the iphone with the 3.1.3 firmware) – could i use RedSn0w 0.9.4 to jailbreak it? – I do not need the unlock, just need to jailbreak and install apps..

I have read a few website stating that it would work for iphone 3Gs – with an older bootrom (or something like this) – can you please help clarify how do i check if it is an older bootrom?

Thank you.

Put your iPhone in DFU mode and Go To Start->Control Panel->Device Manager. In the Universal Serial BUS Controller, you will find Apple Mobile Device USB Driver.

Now Right Click and go to Properties, go to Details tab and select “Device Instance Path” from the drop down list box. There you will find [iBoot-359.x] at the end.

Okay, this is strange… I upgraded my Iphone to 3.1.3 firmware and for whatever reason I downgraded it, and I DON’T remember how I did it. But I now have the cydia unlock FOR FIRMWARE 3.1.3. and it’s not registering with the 3.1.2. firmware. I tried restoring it to the original settings so that I can get the older version of cydia but I cant restore it WITHOUT first downloading the new 3.1.3. firmware. Any help on how I can get the OLD cydia?

Hi: I just recently purchased an iPhone 3G with an AT&t sim card activation. Is there anyway I can jailbreak it without having to worry about not being able to get Rock and Cydia??

What’s the diff btwn jailbreak and unlock?

I have the iPhone 2G with 3.1.2, and it is still jailbroken, is there a way I can activate it without worrying about It being automatically updated in iTunes. Because iTunes automatically put the latest firmware on the phone when it is being activated right??

If you can answer A question I would greatly appreciate it.

Thanks.

Can confirm, this does work for jailbreaking an Iphone 3G on 3.1.3.

MAKE SURE TO DE-SELECT “Already Pwned” if you Iphone 3G is NOT already Jailbroken. Just follow the steps in the tutorial and you’ll be fine.

try to follow the direction above, but unchecked the already pwned. automatically it will put cydia icon on ur menu, then try to downgrade ur baseband with fuzzy band(it will only succeed if ur bootloader is 5.08, to find out ur bootloader, just install fuzzyband it will give u the info). if it works, ur baseband(check in setting, general, about, modem firmware, it wont be 05.12.01 anymore) u should be able to use the old os 3.1.2. ur iphone is jailbroken and unlocked.

ocheap says:

but if it isn’t working(bootloader not 5.08), then the problem is in the hardware, need an expert to go down that deep.

ATTENTION ALL ((((NEW)))) 3G iPHONE USERS If your iPhone came with OS 3.1.3 And you are suffuring that black screen at waiting to boot, this is what I literally just did to fix this problem..

1.) Open Redsn0W 2.) Follow instructions BUT DON’T CHECK ANYTHING BUT INSTALL CYDIA

3.) Follow DFU instructions 4.) Once you get that damn error, you need to do this..

5.) REBOOT YOUR COMPUTER 6.) LOG IN AND REDO THE REDSN0W EXACTLY AS I MENTIONED ABOVE 7.) On the DFU part it should automatically skip it and you will get pass that damn waiting to boot.

This was performed on my iPhone 3G, OS 3.1.3 (Now Jailbroken) Base: 5.12.01 Bootrom(w/e): 6.4

If this helped, thanks??

really quick ppl 3gs 3.1.3 5.12 cannot be broken/unlocked or downgraded can be jb only if you did it while 3.1.2 and then updated it with a jailbroken 3.1.3 can be downgraded only if when you using cydia and on the top says you have a ssh of 3.x on file then you can downgrade. but there is a procedure. besides that if you update to factory default 3gs 3.1.3 5.12 with itunes and nothing else.

You are shit out of luck.

I was actually able to downgrade my iphone 3gs (old one MB) from 3.1.3 to 3.1.2 after i accidently upgraded it. Just restored using the 3.1.2 firmware on itunes and then used iRecover to get it out of the DFU mode. Then was able to use blackra1n and jailbreak it. Was so happy it worked, i thought i was stuck with a normal iphone and was bummed because i wasn’t able to tether 3g to my ipad.

I have an international version of a 3G 16GB iPhone (model MC131ZP) from Hong Kong that was purchased directly from Apple unlocked so that I can swap SIM chips wherever I travel to. It is running the original 3.1.2 OS. Blackra1n was successfully installed on this phone. It was never used and I have no intention of ever using it. I now wish to (a) upgrade the OS to 3.1.3 and (b) to remove any effects of having jailbroken the phone with Blackra1n. What will happen if I upgrade? I’m worried that if I upgrade to 3.1.3, the phone will lock up on me. Any advice would be appreciated.

To let people know, my iPhone 3G is jailbroken and unlocked on the 3.1.3 and firmware 5.12.1…

It took me 3 days to figure how to do this as I thought I broke the phone upgrading accidently as it always said no service etc…

To unlock your phone to every network again, Buy a PAYG sim. Ring the sim service provider to register it etc.. Insert the sim and tell them it’s saying no service…

Then they’ll say some cock and bull… Tell them you bought the iPhone off ebay and it said there it was unlocked to every network.

Tell them to check your IMEI NUMBER to see if it’s got a restriction on…

Obviously it will have and they’ll lift the restriction for you for free..

I’ll post an instruction on here later on how to jailbreak your iPhone on the 3.1.3 and modem firmware 5.12.1..

It worked for my 3G Iphone, but I tried slightly different way. Just check cydia button not already pwned and then you will see procedure about how long you will hold which button. And enjoy if it works.

“unable to recognize specified ipsw” iphone 3g 3.1.3fw 5.12.01bb this is the message i keep getting, after using redsn0w 0.9.3 and 0.9.4. i have used 2 different 3.1.2 ipsw files downloaded from diff. sources and i get the same thing. what is my issue? do i need any additional files, e.g. bootloaders, i need to unlock this phone period, and i would need afc2 support with my jailbreak as my initial jb killed my wifi?? hlp pls Reply
