I have a verizon lg g2 ( vs980 ) I downloaded a custom rom, went to flash it but it failed. I had already wiped my system and have no nandroid backup on the device.. But I do on my pc. I have twrp installed and I can still access that. I have tried the lg g2 flash tool 2014 but I keep getting error saying server connection timeout. I dont know what else I can try. I attempted adb sideload in twrp it just keeps loading in the progress bar and doesn't stop. but never used it before is it possible to push a zip to the phone any other way? I have adb fastboot for windows 8.1 but I cannot figure out how to get my phone into adb mode in the state its in.
BACK UP AND RUNNING!
How did I do it?
went out and bought a micro usb to usb connector and a usb thumb drive, downloaded xdadebs custom rom,gapps,lgapps.. flashed over twrp and BOOM. now that I was back up and running it was as easy as copying my nandroid backup back to the phone.
thanks to everyone that tried to help me
Keep a nandroid backup on phone.
