Remount HTC Desire
Bit of an old thread,
But I've never had the remount work on my HTC Desire (rooted, running Oxygen 2.2.2/Amon RA 2.0.2 Recovery)..
What I do is reboot in to recovery, mount /system and then use ADB to shell in and edit the files.
If I do a remount rw, It appears to edit the file, but as soon as I reboot, any changes are gone..
