i will make it quick, my father suicided yesterday 6:30 pm yesterday, and i have the task to figure out if he left a note or something inside the phone, it is a lg g5 with 4gb of ram, it is pattern protected and i cant access the phone, i know i can delete the pattern if i do a hard reset but the data inside the phone it is extremely important for me, also i know that if this phone had installed TWRP already installed i could simply delete the files and get it running again but obviously this is not possible since is a stock phone, non modded and non rooted, any help on how i could get the pattern lock to disapear without losing data would be great
