12/20 iPod 4g bootloader bugged?

Hi, I've been using rockbox for a while and I love it. Recently I went to upgrade rockbox, but I didn't have a backup and noticed there was a new install method, so I restored the iPod and started from scratch. Now I've installed this bootloader multiple times now (clean restore before each one) and it boots into rockbox fine, but whenever I hold the menu to go into original firmware, it says it's doing it, but then immediately resets, and it does it every time. I couldn't find an answer in these forums from searching. Is it a bug in the bootloader, or am I doing something wrong with the new process?

Thanks,
JM

Sorry for taking so long to reply.

Yes, a few others have reported similar problems with the new bootloaders on the older ipods, and I haven't been able to find the problem.

Could you try the following and post the output of the two ipodpatcher --list commands? The extra "-v" option provides more debugging information for me.

1) Restore your firmware partition to its original state (i.e. no Rockbox bootloader).

2) Run "ipodpatcher [device] -v --list"

3) Install the bootloader using "ipodpatcher [device] -a bootloader-ipod4g.ipod"

4) Run "ipodpatcher [device] -v --list"

There is an alternative (currently undocumented) method of starting the Apple firmware, which could also be useful for you to try:

1) Restore your firmware partition to its original state (i.e. no Rockbox bootloader)

2) Extract the Apple firmware to a file using "ipodpatcher [device] -rf apple_os.ipod"

3) Copy that apple_os.ipod to the root of your ipod - i.e. the same place as the rockbox.ipod file lives.

4) Install the Rockbox bootloader using the -wf command - "ipodpatcher [device] -wf bootloader-ipod4g.ipod"

This method completely replaces the Apple firmware in the firmware partition with the Rockbox bootloader (you should notice much faster boot times), and loads it from the apple_os.ipod file on your FAT32 when requested.

I hope that you will soon also be able to select the "apple_os.ipod" file from within Rockbox to start the original firmware, but that isn't working yet.

I'm having the same problem on the 2nd Gen. Mini.
I tried the alternative method, and continue to have the same problem, except that instead of saying "loading original firmware," then shutting down and restarting, it says "loading apple_os.ipod." I can't get back into the original firmware at all. Rockbox really does boot faster though.

I know it's not the same ipod as the original poster, but I went ahead and saved the "--list" results anyway.

Thanks for the info. I'll post here if I discover anything.
