The BEST way to flash the Linux Motorola's is to use RSD Lite higher than 4.1
This is the way i Flash my Linux Motorola's
i would not recommend using Flash&Back on any MagX phone
(try to avoid RSD Lite 4.1)
Please DO NOT request ANY RSD Lite
To find the NEWEST RSD Lite search Google or 4Shared
Next, install the NEWEST Motorola Drivers from MotoDev
Now, choose the NEWEST Reflash, that allows External Skin to be added,
Flashing,
Once you have the above 3 your ready to Flash your Motorola, and your Battery is FULLY charged.
Connect the phone to the PC with the USB cable, making sure the phone is in Modem Mode,
(this can be checked by going, Main Menu> Settings> Connections> USB Settings> then select Modem.)
Now start RSD Lite.
wait for it to find your Phone,

Now you need to choose the file you want to flash,

Once you've selected the right flash, you can press Start,
Let RSD Lite go through the Flashing cycle,



Your Phone will Re-Start, DON'T disconnect until the Result is PASS.

Congratulations, You've Flashed Your Phone

If your having troubles with Windows
Seven/Vista
You need to copy the firmware you want to flash into the RSDlite directory in your program files folder.
Make sure you are in bootloader mode first.
Then, open command prompt and "cd" to the RSDlite directory
eg:
cd C:
cd Program Files
cd motorola
cd RSDlite
