[Q] flashing recovery and Rom from a new user
So I've rooted devices before, but this is all new to me. Its been a few years so please forgive me.
I have a LG G2 V980 from Verizon. So far I've managed to root with ioroot post 4.4.2 update. I have the Rom I want on my' sdcard' or whatever you want to call the root. For the life of me, I can't figure out how to actually flash it (is that the right term for installing a rom?).
I believe my issue is in the recovery. The guide for the Rom says to use twrp but I don't seem to understand how to install that either. I've used flashify and Rom manager But to no avail. When it does boot into it, or at least I think I am, there is an error message about authenticity then a blank screen.
Does anyone know what's going on here or can point me in the direction I need?
Thank you all for the help.
