I have [NOT] bricked my snsa e200! help!
Bagder:
First, this doesn't make sense. For Rockbox to boot thus far, there must be an existing Sansa bootloader working and that is the same bootloader that provides the recovery mode. Your failure to enter that mode is probably more related to user fiddling or problems with your USB port or similar.
Likewise, the problem with the manufacture mode is also most likely addressable by you trying several times or trying another USB port on your computer. Of course as I mention above, you shouldn't need to use the manufacture mode.

Now when i turn on my sansa it loads the rockbox bootloader and says it can't find the two firmwares. I am a total noob and am using windows xp.

Pretty sure you can't delete the original firmware.
Do know how to get to the original firmware with your new bootloader?
Press and hold the left arrow key while powering up.
I bet you have your Sansa in the wrong USB mode that is exactly the reason yuou cannot see it on your computer.....you need to change that in Settings in the original firmware. I think it should be MSC (Mass Storage mode).

okay, fixed it
I followed these instructions from here: http://www.rockbox.org/twiki/bin/view/Main/SansaE200Unbrick
--- Quote --- Manufacturing Mode
At times people mess up the bootloader and then the recovery mode doesn't work (In the sense that you cannot enter recovery mode anymore). In this unlikely case, you can enter manufacturing mode and use the e200tool to restore the bootloader.
You can download the sourcecode for e200tool as well as a compiled Linux binary from http://daniel.haxx.se/sansa/e200tool.html Note: Do not follow the instructions on that page, you might further brick your player.
The e200tool works fine under Linux, *BSD and Mac OS X or similar systems, as long as you have libusb installed. If you are a Windows user, you should consider booting from a Linux Live-CD, as getting e200tool to work under Windows is extremely difficult and not recommended.
To recover from manufacturing mode, you also need to have a working bootloader file (which has .rom as filename extension). You can download bootloader files from http://daniel.haxx.se/sansa/mi4.html
You can boot into the manufacturing mode as follows:
* Power off
* Turn ON lock/hold
* Hold down center select button
* Insert USB cable
The screen should stay black with the blue ring lit. A new USB device should get detected.
Once inside manufacturing mode, use the following command to copy and load the original bootloader to the device:
e200tool recover BL_SD_boardSupportSD.rom
While e200tool writes the file to the device, you need to hold down the record button on your player! Hold it until the device enters recovery mode.
You should now be in recovery mode. Continue with the bootloader reinstallation as described in the previous section.
NOTE that if you have an e200R model, you want to recover to the BL file mentioned above, but then when it goes into recovery mode you really really want to install the binary-patched e200R model bootloader.

Then I did This.
--- Quote --- Restoring the original firmware
When "Welcome to Recovery Mode" appears you copy an original firmware .mi4 file (if you don't have one try here) to the device and disconnect it. It will cause the device to reinstall the original firmware. A corresponding message should appear on screen.
In most cases, this should be enough to get your device working again. Only continue with the next step if this step did not help.
Formatting the device
NOTE This step does format your device, you will lose all data stored on it. WARNING
If the previous step did not work, you might have to reformat your device. Enter recovery mode again and after copying the.mi4 file, create a file named sansa.fmt on the device. ('touch sansa.fmt').
After you disconnect the device, it should say 'Formatting' on the screen. Be patient, this can take a few minutes.
Restoring the bootloader
NOTE This step can brick your device further and may require you to enter manufacturing mode. This step also formats your device so you lose all data stored on it. WARNING
If the previous step did not work, or you had to enter the recovery mode through manufacturing mode, you need to reinstall the bootloader.
Enter recovery mode again and do the following:
* Copy the .mi4 file
* Copy a bootloader .rom file which is compatible with your firmware file
* Create a file named sansa.fmt on the device
Next disconnect and wait till after it has formatted your device.
