First of all. I have a problem I can not delete the basic device software note I have root authority
II. Was installed busyBox but I can not install it and when the installation device works Risterat What problem
read about write system protection.
tutos are available on this forum (wp_mod.ko file to push in system/lib/modules, and run a command on the phone with a terminal app)
if im speaking chinese, dont try
but as you tried to change partitions before having write protection removed, you wont be able to do it without a restart until you reflash your rom (clean install)
Quoted from Step 2 Here,
2. Hopefully you were able to successfully install custom recovery and root.
Now this part is a bit tricky. Even with root HTC is stopping us from writing to system. For this we need to apply the wp_mod.ko module.
Download it here: http://forum.xda-developers.com/show....php?t=2707378
Copy this file to the root of your internal storage.
Now download Terminal Emulator from play store, run it and enter the following commands (you only need to do this once):
Once you do this go into a root explorer app and mount /system as R/W. Copy the wp_mod.ko file to /system/lib/modules
Now go to /system/etc and find install-recovery.sh. Open it with a text editor and add a new line at the end with the following:
Reboot! If all went well the wp_mod module will run at boot every time so you won't have to do it manually each time!
Congratulations, you now have a fully rooted Desire 816!
