Thanks, I had assumed, incorrectly, that 5.5 referred to the iTunes7 firmware (due to its integration), and not that 5.5G meant the 80GB ipod (if that is even correct).

This would mean, previous 5G models, (e.g. M# - A1136) [mine] should work fine with Rockbox if one can figure out how to go to earlier firmware? I say this because under the iTunes7 firmware it would not build correctly through command prompt.

Thanks, I definitely should have seen if it supports NTFS before attempting to port it on my iPod, as for 5.5G - you can see in my previous reply that I had thought it to reference iTunes7 firmware and not the new models (80GB), thus, my 60GB 5G Model (A1136) should have accepted it fine... however, iTunes7 firmware prevented the successful build.. etc..

if i understand you correctly you did not consider that 5.5gs have different firmwares than 5gs and that you can't upgrade/downgrade your pod with a firmware for the other type. in other words: they look the same, but they are different models as far as the firmwares are concerned.

There's also two categories of 5G, the ones that come preloaded with 5.5G firmware, and the ones that have been upgraded. The ones that are preloaded seem to suffer the same disk-sector problem as the full 5.5Gs, despite technically being 5Gs.

Thanks for the help on how to put it in disk mode, from that I was able to use a friend's computer which has not been upgraded to iTunes7 to restore to a previous updater (2006-06-28).

I had confused 5.5G referring to FIRMWARE and not hardware. The 5.5G model numbers are the following (since they kept the 30gb):

White:
30GB - MA444LLA
80GB - MA448LLA
Black:
30GB - MA446LLA
80GB - MA450LLA

Your iPod may also be 5.5G if you purchased it AFTER 09/2006...

I suspect that iTunes7 writes great registry values to the computer, even though I ran Registry Mechanic after uninstalling it, it would still 1) crash iPod Wizard and 2) crash all updaters EXCEPT 2006-06-28, which told me to use iTunes7 to update.

On my friend's computer, I installed the 2006-06-28 updater and after throwing my sucker into disk mode was able to downgrade the firmware that way. The problem was that the current methods would not work... that is, use iPod Wizard (crashed on me) or edit an iPod file through notepad, replacing values to those of earlier firmware then running that - this failed for me because iTunes7 firmware removes that editable section.

Essentially, I am unsure if this part is necessary, but I used the NTFS format, plugged it into a comp that has never seen iTunes7 and ran an earlier updater sucessfully. If someone can find the right registry keys to delete, this would probably negate the problem of having to use another computer... Another tidbit is that iPod Wizard 1.2 did NOT crash on his computer, although it gave me that great critical error and crashed on mine.

Thanks a ton for your help guys, I really appreciate it!

Alright, here's the final...

If you have upgraded to iTunes7 and the bundled firmware, this is how you can go about downgrading it...

1) Uninstall iTunes 7 (Run a registry cleaner if possible)
2) Start > Run > Cmd > Regedit
3) Local Machine > Software > Apple Computer > iPod > Delete ALL Keys
4) Current User > Software > Apple Computer > iPod > Delete ALL Keys
5) Restart

Bear in mind:
1) Prior to removing registry keys, but after uninstalling iTunes7, iPod Wizard would crash as soon as it was opened.
2)Prior to removing registry keys, but after uninstalling iTunes7, the 2006-06-28 Updater would indicate that it was obsolete and I needed to update through iTunes7.
3) The second method of editing the 'SysInfo' in notepad does NOT work if you have upgraded to iTunes7, it WILL work if you follow these steps and go back to an earlier firmware (the last working firmware is 2006-06-28).
