Did you run Sansapatcher as root?

[Bor]

Yes as root
I try it Gentoo Linux x86 and amd64
from
http://download.rockbox.org/bootloader/sandisk-sansa/sansapatcher/linux32x86/sansapatcher
and compiled from svn too

Also in WinXP64 run as admin from
http://download.rockbox.org/bootloader/sandisk-sansa/sansapatcher/win32/sansapatcher.exe

Found info about rockbox does not work with version 1.01.07

http://forums.rockbox.org/index.php?topic=15778.0

So I downgrade to 1.01.06
and try again

and

[INFO] Bootloader installed successfully.

Looks like there's only an older version here:

As one of the sad and angry  who installed the 1.01.07 before finding rockbox, where do I find the 1.01.06(E in my case) and how do I go about to donwgrade my c250?

[MarcGuay]

Read the SansaC200 wiki page.

You can find the firmware here

Thanks for the reply.
Some comments on downgrading... (I found out the hard way. )
The firmware files are in 7zip format, so one needs to download the tools to un7zip them. (Google is your friend, also found the tools are easily installed in ubuntu)
After that, just follow the instructions for enabling service mode and install old software.

It took me better part of the evening, but now my mp3-player is running rockbox. Many thanks!

How does one stay up to date to know when RB will support .07 firmware?

[Llorean]

Watch the changelog for a commit relevant to sansapatcher.

[bluebrother]

Well, IIRC the .07 firmware is already supported by sansapatcher, but no new binary release has been made since. You can build sansapatcher yourself. I'm preparing a couple of bigger changes to Rockbox Utility and most likely will provide a test binary then, as Rockbox Utility uses sansapatcher itself it will then also allow installing on .07. You might want to keep an eye on the RockboxUtility wiki page for that.

[robin0800]

Yes I can confirm the sansapatcher in svn does work with the latest firmware.
The latest firmware reinstates the USB setting so is worth while all round IMHO.

[bluebrother]

I've uploaded a new windows binary of Rockbox Utility: http://www.stud.uni-karlsruhe.de/~uhcn/rockbox/rbutil/rbutilqt.7z
This is built from current svn with my current ongoing internal bootloader rework (shouldn't change much from a users point of view). This should work with the c200 '07 firmware. Feel free to try other bootloader installs too and report major issues to me (I'm aware of several minor glitches). Keep in mind that this isn't tested very well as of now.

[robin0800]

Just tried New RBUtil and although it will install Rockbox, after warning a boot loader is already present, then says no sansaC200  found.

Sansapatcher made from svn still works and really strange RButil 1.0.6 (July) can now reinstall bootloader.
