Warning: Apple Stops Signing Firmware 3.1.2 For iPhone 3GS

by Mr. Ex on February 3rd, 2010

iPhone 3GS and iPod Touch 3G owners that are or have interest in Jailbreaking their device, listen up!

Today, Apple stopped signing iPhone firmware 3.1.2. What this means is that those owners of an iPhone 3GS or iPod Touch 3G who had updated to firmware 3.1.3 and who did not use Cydia to store their TSS will not be able to restore to anything but firmware 3.1.3.

With the recent firmware 3.1.3 update, many iPhone 3GS/iPod Touch 3G owners jumped the gun to 3.1.3 and have now been trying to revert back to 3.1.2 to regain their jailbreak and/or unlock. Unfortunately that will not work due to Apple no longer signing 3.1.2 firmware for iPhone 3GS and iPod Touch 3G hardware.

Current iPhone 3GS and iPod Touch 3G users of firmware 3.1.2 that want to keep jailbroken, Big Boss warns to make sure that you are very careful with what you do from now until the next jailbroken firmware. In other words, do not do anything that could potentially require your iPhone 3GS or iPod Touch 3G to need to be restored.

Big Boss recommends that users install OpenSSH and learn how to use it so that specific fixes can be performed without the need for a restore.

This is funny... It seems that EVERY time apple releases an update, users need to be warned not to update yet! When will people learn?!

OFFICIAL: Downgraded 3.1.3 to 3.1.2 by fooling Itunes with Sauriks help on Cydia shsh.....BUT the only problem is.....baseband has stayed at 5.12 and not back to 5.11..which means that blackra1n works for it just fine.....just not working for the baseband help......if any one has tips on how to do that.....that be sweet!!!

Ok, something is wierd.....I bought a new 3gs and happened to get all of my custom stuff back on my phone that i had previous when i used blackra1n ( fiveicon dock, smoothboard etc etc )........but now, every time my phone turns off it goes into DFU mode and i have to use blackra1n every time to use my phone.....again and everything is still there! Any one have this problem? Cause its never happened to me before......and if so does any one know how to fix it?

I just did a successful restore with a custom IPSW (3.1.2 7D11) at 4:15AM EST, February 4, 2010. Everything is working fine.

- launch-day iPhone 3GS
- was on stock 3.1.2(7D11)
- never previously jailbroken
- iTunes version 9.0.1.8

Mr. Ex

That's fine.
It's only if you updated 3.1.3 and then went back

Rob

Wrong answer Zero...if you are running 3.1.2 you cannot restore to any firmware but 3.1.3 unless you stored shsh signature on cydia or other server.

Mr. Ex

Thank you for clarifying for users reading.
