1602 and 1604 errors when updating to 1.1.3 firmware

So like many people today, I tried to update my Touch's firmware to 1.1.3. Using iTunes 7.6, I downloaded the file, but then when it goes to update, it gets stuck on the "Preparing iPod for update" step and then comes back telling me that the iPod could not be updated, giving either a 1602 or 1604 error. I can restore back to the 1.1.2 firmware with no problems, but after multiple attempts, multiple reboots, multiple reinstalls of iTunes, and multiple forced restores, I still can't update the firmware to 1.1.3, getting the same error each time. A quick Google search reveals that I'm not the only one having this problem, so I hope a fix is worked out quickly. I guess I shouldn't be in much of a hurry, seeing as there appear to be a slew of other problems with the new application pack anyway.

Same problem here. I've tried everything short of restoring the iPod itself, and nothing works.

Everyone reading this should be aware, though, that this is prior to purchasing the new applications package. This is just the free 1.1.3 update that fails; I haven't bought the January update yet since I haven't been able to get past this step.

I had all of these problems, and I was able to fix them with the following process. Here is what I did:

My setup:

Apple Max OS 10.4.10, Mac G4, with 3rd party USB 2.0 card.

1. Upgrade to iTunes 7.6 and Quicktime 7.4, Restart and repair permissions

2. Purchase the iPod Touch Upgrade - It took two tries to purchase. I had to accept to two agreements, and then got an error. I purchased the upgrade again and got an instruction screen. iTunes appeared to download a very small file.

3. Sync my touch (I still had not upgraded to firmware 1.1.3)

4. The touch synced, but I had no new functions.

5. I clicked upgrade, and downloaded the 165GB file.

6. While the file was downloading I undocked my iPod touch and restarted it.

7. When the download was complete, it gave me an unknown error because my iPod was not connected.
8. I connected My iPod and tried to install the update. After several tries, I always got a 1602 error.

9. I restarted my computer and did a hard restart of my ipod touch. This did not work, I still had 1602 errors.

10. At this point, I chose to RESTORE my iPod Touch.

11. After the restore, I chose not to restore any content, and just tested the firmware update. EVERYTHING worked great!

12. I synced my iPod touch while I watched the keynote. 45 minutes later my sync was complete and 14 Gig of content was restored. The new functions are great. I have already read my .Mac email.

what i did was this (mind you, I'm using Windows XP and i did update Itunes to the current version)

I downloaded the new 1.1.3 firmware and then when I hit restore, I also held down the shift key, navigated my way to the where the firmware was downlowded and then selected the firmware. After that, it seemed to restore and install the firmware.
