I have an e250R v1 confirmed. My modes list as Rhapsody and Play for Sure, so I believe that makes it an R.
I run the e200rpatcher.linux. I start the unit with hold activated, press select, connect to usb (man mode I believe)
The e200rpatcher connects, gives a message that upload was successful, however the screen on the sansa reads
Unknown bootloader
Rockbox installer cannot continue
What's wrong?
Thanks

The patching application that e200rpatcher uploads to your Sansa performs a check to see if the Sandisk bootloader installed on your device is either the e200r bootloader , the patched for Rockbox version of that bootloader, or any of the known e200 bootloaders.
That error message is displayed when all those checks fail.
I'm not sure what to suggest - I can't recall anyone else ever reporting this problem.
If you can compile things yourself, you could try commenting out that check in bootloader/main-e200r-installer.c but I'm not sure if that's a good idea...

I'm not sure what the problem is, but I followed this link to restore the bootloader
http://www.rockbox.org/twiki/bin/view/Main/SansaE200Unbrick
Everything worked OK there. So I should now have a wrking bootloader.
I then tried the e200rpatch again with the same results.
I would imagine if my bootlader was not correct the sansa would not boot at all.
That is not the case, the sansa boots fine???
As a side note, when I connect sansa in Rhapsody (MSC) mode, Linux mounts it read only.
Even as root user I cannot write. Does that help?

That usually means a corrupted file system or flash I think.
-
OK, if it is a corrupted filesystem or flash, what can I do to fix it?
-
When Linux detects a bad FAT file system it remounts it as read-only. 'dmesg' should tell you if that's the case.
If that's what happening, the FAT file system on your sansa's NAND flash is messed up and you need to fix it.
-
To 'format' the Sansa's memory, make a folder called "sansa.fmt" and drag it into the sansa's root directory. Allow it to reboot- when it restarts it will find that file (which is a signal to reformat) and it will do just that.
ALL OF YOUR MUSIC AND FILES AND FOLDERS WILL BE GONE.
You'll have to then re-copy the rockbox folder to the player as well as your tunes and stuff...
