OK forget about my first post.
I just reflashed my phone both firmware and emmc, now im off to a fresh start.

I have kernel power installed, leafpad and multiboot too, following this instructions right now:

sudo gainroot
mkdir /and
success
mount /home /and
success
apt-get install multiboot multiboot-kernel-power bzip2
success
cd /home/user/MyDocs
bzip2 -d NitDroid-0.0.8-Popov.tar.bz2
success
cd /and
tar xvf /home/user/MyDocs/NitDroid-0.0.8-Popov.tar
success
dpkg -i /home/user/MyDocs/nitdroid-kernel-2.6.28-06_final1_armel.deb
-still on:
Running depmod...
Creating item file for multiboot

tried to enter umount /and
phone responded with: cannot umount Device or resource busy.

how long does that step take?

OMG i finished the steps AND I ONLY HAVE NITDROID on choices.
WTF?
i give up.
reflashing my phone and never doing this again. LOL
