Bad Checksum

[benny1133]

I have a 60g 5th generation ipod. I followed the instructions severelly times and reinstalled rockbox more than once. Each time i get the error of bad checksum. Is their anything i can do to fix it? Maybe manually change the sum? please help

Which files, exactly, have you downloaded?

[benny1133]

I downloaded the ones for the 60/80g ipod

[Llorean]

I said "exactly". Bad checksum means either you accidentally downloaded the wrong one, or the file got corrupted while you were copying it.

Can you post the output of the bootloader?  i.e. the checksums that are displayed?

i downloaded the current build of the 60/80g ipod
and the message is as follows:

Rockbox boot loader

The build you downloaded is the iPod Color build. You've downloaded the wrong one.

ok i will try again but i'm pretty sure i clicked on the ipod video one

[Llorean]

Well, that "ipco" in there means "ipod color".

i removed the old rockbox installed the new one and got the same message with different numbers:

Did you download the build for the 30GB models, or the one for the 60/80GB models? This is important to note.

[benny1133]

i clicked on the 60/80 link....so i belive that i downloaded that one

To use the 30GB build on an 60/80GB Ipod is also possible (if you accidentally downloaded that) maybe it could decrease battery life a bit. It doesn't cause any problems as the different way round, it just doesn't use all of the available RAM.

I've heard of this as well, but at the same time I've been told that using the exact build for your iPod video is always best.

but neither one works... any ideas
