Update bootloader problem on IPOD 5G 30GB

[Greenleaves]

I tried to update the bootloader on my iPOD 5G 30gb but the ipodpatcher (May 24, 07 version) could not find my iPOD connected in disk mode to my windows PC.  However I was able to upload the SVN build on the iPOD with no problem.  Any idea?

Thank you.

Why were you trying to update the bootloader ?

Why were you trying to update the bootloader ?

The changes:

2007-03-04: Dual processor support added for PortalPlayer (iPods, H10, Sansa) targets, requiring an update to the latest bootloader.

Wow - you've not updated in a while then huh?

Are you logged into Windows as the Admin user ?

Just tried on Ubuntu 7.04 under root. ipodpatcher still couldn't find ipod.

In Linux (I'm a Linux user, so can help you better there), can you type "fdisk -l" ?  That should list all the disks attached to your computer, and display their partition tables.

You should be able to identify your ipod by 1) Disk size will be 30GB; 2) The first partition will be of type 0 (Empty); 3) The second partition will be of type 0xb (FAT32).

Assuming your ipod is visible (if not, then that's the cause of the problem...), type

./ipodpatcher /dev/sdx

(replacing /dev/sdx with the device you've identified to be your ipod - e.g. /dev/sda) and then see what it says.  It should give you slightly more explanation about why it doesn't think it's an ipod.

No luck. Tried fdisk -l, and here is what I got:

Disk /dev/sda: 30.0 GB, 30005821440 bytes
255 heads, 63 sectors/track, 3648 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Looks like the patcher couldn't recognize the partition.  

Many thanks ...

DELETED A BUNCH OF STUFF THAT WAS WRONG

Edit :

You could try changing the partition type of /dev/sda2 to "b" instead of "c".

I *think* you can get away with this without losing any data.

[linuxstb]

Yes, the reason ipodpatcher doesn't detect the ipod is because the partition type is "c".  It is expecting it to be "b".

And yes, you can change it without losing any data.  In Linux, do the following:

fdisk /dev/sda
Enter "t" (to change partition type)
Enter "2" (for partition 2)
Enter "b" (the new type)

Now enter "p" to view the new partition table, and if it looks right (i.e. the c has been replaced by a b), type "w" to write the new partition table.

At any time before entering 'w", you can just enter "q" to exit fdisk, and it won't save any changes to your ipod.

Out of curiosity, do you know how your ipod came to have a partition of type "c" instead of the usual "b" ?  Did you ever repartition your ipod, or reformat it using something other than itunes?

[Greenleaves]

I managed to change the device Id to "b". Now problem is fixed.

Sorry I can't recall how it came about having the device Id as "c". I must say I haven't updated the Rockbox firmware for quite some time.  I am happy to see now Rockbox supports the dual core, and that hopefully will extend the battery life.  

Many thanks for the great work. Appreciate it very much.
