    In all the instructions that involve changing files under /system, I see that the first thing to do is to mount it as read-writeable, then at the end, mount it as read only:

    su
    mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
    ...
    mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system

    However, I'm finding that I can read-write files in the /system directory just fine without all the remounting. Does anyone know what this could mean? My phone seems to be functioning just fine so far. Should I try mounting /system as ro like in the last step just to be safe?

    I see, so it's not for any subdirectory or file under /system, but only for editing/creating files/directories under the bin subdirectory?

    EDIT:

    I've attached a couple very simple scripts (just copy-pastes of the actual commands) you can put into the /system/xbin folder to simplify the process of mounting /system to be read-only and read-write. Remove the '.txt' before putting them on there.

    Saves a lot of typing and removes potential for typos.

    I am trying to mount my /system folder, and it appears to work how ever when i try to copy a file up with the "adb push" permission denied.

    any idea why?

    I must be running this command wrong somehow...
