@NvyUs, you have to unmount before proceed,
sudo gainroot
umount /dev/mmcblk1
then your commands
=======================================

For people really really want to watch TVs
1) install flash 10.1
2) go Android Market, dl and install
a) TV.com
b) Discovery

TV.com has CBS/CW/ET/InsideEdition/CSI (Full 40 min episodes)....
Video does NOT play smoothly, it is full screen, some choppiness, like missing 1 frame for every 3, kind of like that. It is watchable though. Audio is very smooth. On ESPN/WRAL, video is only half of the screen, it is very smooth. It plays smooth on smaller screen but choppy on full screen, maybe cache/memory problem?

Still looking for Opera Mini and Google Maps......anyone got it...yet? I really enjoy this nitdroid thing, it bred new life into this somewhat dormant Diablo....
