Software: Firmware Upgarde Issue: Will not upgrade to 3.1.2 From 3.0

Hello my fellow ifixit community. I have a question which perplexes me. I have an original 8gb iPhone. I just updated the firmware from 2.0.2 to 3.0. Yes i know, it was long overdue, but this was for a client that needed their phone jailbroken and unlocked. After this was completed, i decided to update the phone firmware to 3.1.2. I tried over 10 times (13 to be exact. I tired with various versions of 3.1.2. (original firmware from apple, custom firmware, and firm downloaded from 3rd party sites), but the firmware didn't go through. Various different errors came up. I thought to myself, maybe i have to upgrade this firmware by firmware (Ex. 3.0, 3.0.1, 3.1, 3.1.2, etc.). This didn't work. The only firmware that would download into this phone is 3.0 . This phone has never been dropped or open. So i ask you, my fellow ifixit community, what could possibly be the problem.

Have you tried putting the device into DFU mode before restoring the firmware to it, if not, there might be either a problem with itunes, or the device, did you update itunes to the newest version (9.0.3) and also, i believe apple released firmware 3.1.3 (For iPod touch at least)

Yes, i have tried to put this iPhone in DFU mode. This is how i am able to jailbreak it on 3.0. I also tried to put 3.1.3 but it would not go though. I also updated to the latest version of iTunes. Still no good.
