The Rockbox Sansa c200 port

---

There is a separate rockbox port to the c200v2 models. The v1 hardware uses firmware named 01.xx.xx, while the v2 hardware uses firmware beginning with 03. This version number can be retrieved under Settings->Info.

Install

Full installation and uninstallation instructions for all supported devices are in the Rockbox manual.

If you encounter an error during automated installation on OS X, you may need to launch the RockBox Utility with root permissions. To do this:

• Ensure that the RockboxUtility.app has been copied to your Applications folder.

• Open a terminal window.

• Type sudo /Applications/RockboxUtility.app/Contents/MacOS/RockboxUtility and press return.

Simulator

There are currently simulators for all Rockbox compatible devices. A simulator can be useful for seeing what Rockbox looks and feels like before installing as well as testing out your homemade themes before putting them on your player. The c200 simulator is here.

Troubleshooting

Recovery Mode

Recovery mode can be used to replace a .mi4 image on the player. If you by some reason can't boot into the original firmware, like if you messed up the installation or similar, or you simply want to change the firmware to a different version, recovery mode can be your friend. To get there:

• Power off
• Turn ON lock/hold
• Hold REC button and press MENU button (used to turn the player on/off)
• Plug the player to the computer
• In My Computer you can see new drive 16MB-FORMAT

To update the firmware, copy the unzipped files into the 16mb drive, unplug the player, and release the hold switch.

A word of caution

• Only copy these specific files to the recovery partition.
• Do not format this 16MB drive
• Do not try anything else unless you have to. Again: You might brick your player!

If all else fails, you can try the SansaC200Erase tool to completely wipe your Sansa clean in order to recover it.

Diagnosis Mode

To get into Diag mode ( not the same as recovery mode):

• Power off
• Turn ON lock/hold
• Hold down DOWN BUTTON
• Insert USB cable or press menu/on while holding down button.

The e200tool can be used to unbrick a c200 as long as the diag mode works.

This player is clearly PortalPlayer based and uses mi4 files for upgrading. The mi4code tool on the mi4 site is updated to decrypt these mi4 files out-of-the-box.
