[Q] I need help with a broken LG G2 please topic

My LG G2 recently fell and cracked the screen to the point where I cant see it or the screen doesn't pickup any movement from my fingers. I was able to get a micro usb to usb and plug a mouse in and guess where the mtp mode was so I could at least get my photos off which was successful but I still have important things on it that I need to get. I need to basically be able to control a mouse while the phone is connected to my computer so I can use MYPhone Explorer to extract that data off of it. I understand that you cant use a otg for a mouse and then also have the phone connected to the computer. SO my question is if I use this http : // dckina . com /index . php?main_page=product_info&cPath=6_228&products_id =1619 (remove spaces) will it work? It says MHL but the lg g2 is slimport I believe. If this isnt compatible is there a MHL to slimport adapter? Or is there any other way I can get the information off of it? Please any help would be grately appreciated, Thank you!
