TWRP 3.0.2-0 "unable to wipe /system (device busy) Workaround

Hey guys, I don't know if this has already been addresses, but I will post it anyway.

When installing TWRP 3.0.2-0, you may not be able to wipe /system because the resource is busy.

I have found a workaround for this by using the terminal in TWRP's Advanced Options

Steps:
1. Boot into Recovery by holding the power and volume down button simultaneously until you reach the bootloader.

NOTE: If you get a prompt asking for read/write on system partitions, slide the slider to allow it, you will get stuck if you don't.
NOTE: Check your logs too, the log should be where the Task Switch button us in Android.

2. After TWRP has been loaded, go to Advanced > Terminal

3. Type "umount -l" (without quotations), and press the enter.

INFO: If all goes well, your /system partition should have been unmounted.
INFO: This method can be used for other pesky partitions that need to be unmounted.

Hope this helps! :)
