yes i no i have to remove it, my question is how do it do it via terminal. i no how to do with fastboot like it mentions in the first post, but like i said, i cannot get usb working. my only option is via terminal. =\
Download the Better terminal app from market,
mount, put the file on the root of your SD card, unmount
Open better terminal and enter:
$su ((if prompt opens say allow))
#flash_image recovery /sdcard/recovery-RA-magic-v1.3.2G.img
Worked for me, hope it does for you as well
