I connected my LG D852 with MM to the LG software, I had a pop-up that there is an upgrade so clicked OK thinking that the data will not be wiped as long as I will be still on MM. That was wrong! ALL data are wiped including my newborn first photos which are priceless to me. I tried some apps like diskdigger and some software on the PC but all of them require root to perform. I tried all rooting methods that I am aware of, but nothing is working. I can't downgrade to LP since writing on the internal memory is not a wise move to restore my data. Any ideas how to root that without having to downgrade?
