Hi Nick,

Unfortunately, the process for 3GS is way complicated when it is stuck in Recovery mode and the solution is not guaranteed. Did you ever run Cydia on your 3GS iPhone? Did you ever jailbreak your 3GS? If yes, then we can try few more steps.

blackra1n is not the most elegant jailbreak solution for 3.0 firmware unfortunately. Why don't you try running blackra1n again – give it some time to do its thing and hopefully it will work.

Apple won't let you get to 3.1 or 3.1.2 since 3.1.3 was just released and only 3.1.3 can be applied to your 3GS if all else fails.

i used blackra1n to jailbreak 3.0, but it didnt work, and now im stuck in recovery mode.
i tried to restore using 3.0, 3.0.1, 3.1.2 ipsw files in both dfu and recovory modes, and itunes says that, "this iphone could not be restored, this device isnt eligable for the requested build".

Please follow the error 1600 steps post on this site. Downgrade to 3.0.1 and jailbreak it using resn0w for Windows and then custom firmware it to 3.1.2…

What firmware is on your iPhone right now? You must jailbreak your iPhone before proceeding with 3.1.2 custom firmware… Try blackra1n first at 3.0.x..

If you are planning on using T-Mobile with your iPhone – Download the Activated firmware (T-Mobile and others)…
