Thank you again Nut!! KK it is working awesome for my XZ
I just have some stupid questions they are confusing me...
1. Why do we have to create a backup via TWRP if I don't see when to restore it after installing? Shall we do it? Is it just for precaution? Or does it restore automatically when we install the flashable zip?
2. Does the option "Factory reset" in TWRP is exactly the same as the option of "Factory data reset" in settings menu/Backup & restore?
3. Related to 2nd question, if I also chose to erase internal memory, will I lose root or dual recovery? (In case I would like a very very clean install of 4.4 but with root and dual recovery)
Thanks in advance for your comments
