Rooted my Milestone, how do i have to use ADB?

[justincase]

I have rooted my Milestone today after a full month on 2.1

Now i have a very noobish question, forgive me but this is my first real smartphone with Android OS running on it.

I want to remove Motonav because it really is a pain in the ass, and i red a lot on different forums of how to delete it, using

ADB shell
$ su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock6 /system
# rm /system/app/Motonav.apk
# mount -o ro,remount -t yaffs2 /dev/block/mtdblock6 /system

And that's the part where i get lost :S

Where and how can i run these commands on my Milestone because that ain't clear to me. How can i start ADB shell, do i have to install something, or can i run it from CMD.exe ?

Sorry for the stupidity but i'm surfing the web for 2 days and there ain't no forum or tutorial of where and how to run those commands.

Thank you so much in advance for those who can help me

btw i already know i have to go in debugging mode on my phone..

And i need SDK kit but i dont know what, where and how to install the kit

Ok i managed to get into CMD and my phone got regonized,

now i'm typing in the commands

ADB shell
$ su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock6 /system
# rm /system/app/Motonav.apk
# mount -o ro,remount -t yaffs2 /dev/block/mtdblock6 /system

I get permission denied on

# rm /system/app/Motonav.apk

What am i doing wrong?

chmod it first to get write permission

I dont think its necessary to chmod it at all.

after su, use this command

cat /proc/mtd

And see for which mtd system is listed. I believe its different for south american phones.

And use that mtd to mount.

if that doesnt work, try this

mount -o rw,remount -t yaffs2 /dev/block/mtdblock6 /system

All I've done is rearranged a little bit.

or the method for stupids like me use rootexplorer and klick an "mount as r/w" and then delete all what you want just by klick ...

[Skrilax_CZ]

"mount -o remount,rw /dev/block/mtdblock6 /system" works for me.
