i don't know either for that one, except with proper ruu, but i find out how to backup radio:
"If you want to make a backup of your current radio/baseband, you can do so using ADB. Open a Terminal window or Command Prompt, change into the directory you have ADB installed to, and enter the following two lines:
dd if=/dev/block/mmcblk0p31 of=/sdcard/radio_firmware.img
After you enter the second command, the prompt will appear to be frozen. Just let it sit for a few seconds, it can take anywhere from 10-30 seconds to copy your current radio/baseband software to a file on your sdcard. Once the command has finished, you should see something similar to this:
$ adb shell
# dd if=/dev/block/mmcblk0p31 of=/sdcard/radio_firmware.img
153601+0 records in
153601+0 records out
78643712 bytes transferred in 20.955 secs (3752980 bytes/sec)
You now have a backup of your current radio saved to a file called “radio_firmware.img” on the root of your sdcard."
