Can't install on c240

[kondor-11]

Hi, for some reason none of the downloadable rockbox software can detect my c240. I'm thinking this may be because my player doesn't appear to have an option to change the USB connection method as stated in the rockbox instructions. Is this normal? I have access to an e260 and it has the USB options.

Have you checked to make sure the c200 is a version 1?

There are two possibilties on the c200 why it wouldn't have an option to set it to "MSC" mode which you need for the bootloader installation. (1) As GodEater said, it could be a "v2". Then you're out of luck because Rockbox doesn't run on those currently. (2) Your c200 runs one of the two firmware versions in which Sandisk removed the option for MSC mode in the menu. Unfortunately I didn't get around putting this into the manual yet...  

The easiest and safest way to find out is to check the original firmware's version (in the original firmware chose Settings > System Info) - if the version number starts with "03.xx.xx" then it's a v2. Versions "1.01.05/06" are the ones that don't have the MSC mode setting, then you have a few options what you can do about it (but please, just check first).

Have you even tried to do a manual install?

Ok,

Thanks for the replies. Looks like I'm running 01.01.05P, so that explains the no MSC mode. So you said I have options; I'm guessing changing the original FW somehow?

Yes.  Follow the instructions on the wiki to downgrade to the earlier version of the original firmware.  I believe it is 01.01.01p but don't quote me.  Once you've done that, you'll be able to choose MSC mode in the original firmware. Then, follow the regular installation instructions.

For completeness and since a downgrade is a bit risky, I want to state the other two options too.

Sandisk did not remove the mode itself just the setting in the menu so it is still possible to get to it by - either using Linux (which doesn't care about the MTP mode) - or using a special key sequence, as described by Llorean in IRC (http://www.rockbox.org/irc/log-20071215#10:21:59, discussion starts at 10:03, maybe read a bit further than what I linked to, to read about possible disadvantages).

The firmware downgrade Febs mentioned is explained on the SansaC200Port wiki page, it might save you trouble later but should be done very carefully.

Thanks guys. For now I traded my c240 for my Dad's e260 which I can load Rockbox on but if I end up with the other player again I'll look into downgrading.

or using a special key sequence, as described by Llorean in IRC (http://www.rockbox.org/irc/log-20071215#10:21:59

I added the key sequence to the wiki when I heard about it, for future reference.
