We won't get perm root unless we get a bootloader unlock, and this is also why when I tried dding boot to recovery it didn't work. http://www.modaco.com/forums/topic/...ystem-write-protected-phones-can-anyone-help/ "I am not sure if we can mod the ext_csd or not, I have tried and failed, and there is a lot of info in that csd, but it also has information on any sectors that are to be write protected, this is determined by some params like wp_grp_size and such. Now if the boot loader boots you into regular Android (boot from the "boot" partition" it temporarily write protects those sectors and they can not be changed. If however the boot loader boots you into recovery, the boot loader does not do this. Now there is code in the kernel zImage that denies permission to mounting or remounting /system as r/w. This is why people get permission denied, when they try to remount /system, same thing it is not called if you booted into recovery Since we have the source code to the kernel, you can bypass or removed this code if you want and you will not get the permission denied error anymore when you try to re-mount system, and it will look like you have R/W to the /system partition, and you can delete a file and it will disapear, but as soon as you reboot the phone any changes you made will be gone, because you were only modding the buffer, I have it this way in my CM12.1 I think"
