ok, i entered recovery mode, and loaded temporary bootloader, then i follow these instructions
* Copy the .mi4 file
* Copy a bootloader .rom (or .btl in the case of the R series models) file which is compatible with your firmware file (see here)
* Create a file named sansa.fmt on the device (not c200)
i restart disconnect the device, and screen shuts down and nothing happens.
oh wow, i had to press menu button before disconnecting..
Successfully recovered original firmware

Wow, i feel like a complete moron now. I read that 'how to unbrick' manual for over a bizillion times before.. In fact that was the first place i went to after realized my player is bricked, and didn't realize that my solution was there. and i even had linux installed already... wow. i guess i just needed a pointer to a right direction.
Thanks
