Cannot factory reset phone LG G2
A few weeks ago I bricked my phone and this all happened after I installed a software update. My phone is stock android (D802TA), it has been rooted before though if that matters. As i turn the phone on LG logo shows up, straight after that i get text on the top left of the screen saying "boot cerfification verify" and other stuff then goes into a black screen and stays like that until I turn it off.
I made a thread here saying that i didnt want to factory reset it but now that I can't find a solution i decided to try and factory reset it. the thing is when i press on "Yes" to continue the reset it doesn't work, it just restarts my phone.
