How to remount /system rw on rooted tablet

I am trying to remount my system partition. I can change any file in system.img and boot.img. But I can't get partitions mounted as rw! I am rooted.

#adb remount
remount succeeded

but nothing changes

the same with 

su; mount -o rw,remount...

I set: ro.secure=0 in default.prop

mount cramfs mtd@system /system rw in init.rc

But nothing changes! It is still mounted as ro! What have I do to have /system mounted rw?

Solution

  • It's mounted rw, as mount tells you, but cramfs stands for compressed ROM file system, a filesystem that is intentionally read-only to simplify its implementation, so even if it's mounted rw you cannot change it.
