[Sprint LG G4] TheMadScientist:
first off this is just a quik refrence guide to do it seems to be loads of confussion on how.

the guide is my work nothing else so later on ill post links to all the pages with all the download links so you can thank all respective rom makers and people that created the files and such.

Disclaimer i am on zv6 rooted so i have not tested myself. just put the guide together as one would flash anything to our love to hate g4s.

if issues with rom i dont have a clue again as i am not on zvb. goto rom thread.

so lets get started

first you need to download this this is the zvb .tot

your firmware just incase things go bad.

im assumming you already have lgup or i personally use the old lg flash tool its all personal prefrance this is just for restoring orig firmware incase of bad things.

also download this this is the zvb global rom for sprint g4.

also download this this is the send commands and ports.bat for command prompts to know what to do.

so first on phone enable usb debugging in dev options

i have many firmwares and so ive put all my lg stuff in a lg file ofcoarse for easy accsess.

so unzip the lg root zip to a easy known folder and spot on pc.

after degug open file where lg root is and in a bare spot in folder dont hover over n e file hold shift and left click youll see open command promt here.

click it.

once prompts open type abd devices you should get the dialouge on phone about always accepting this computer or whatever it is click accept.

type adb devices again to make sure pc sees it as adb device and not offline.

once it sees adb device unzip mellowmallow rom .img and put on root directory of internal sd card same root as all the folders like ringtones downloads music and such.

so theres the first steps.

so reboot ure phone into dl mode turn off hold vol up and plug into pc

back in command prompt type

ports.bat this is to see what com number ure device is u want the number with the one that has diag in it not modem

so then type

Send_Command.exe \\.\COM after com type the port that is ure diag in my case currently mine is 14 so for example it would be Send_Command.exe \\.\COM14

as i said the number will change depending on ure pc.

im not running my promt so i dont know exactly what it will say but u will see ure command promt change.

now ure ready and be sure this is correctly entered i just copy and paste for safety then no mistypes.

this is the dd comand to install rom in download mode.

dd if=/data/media/0/MellowMallow_LS991ZVB_v1.01_Global.img bs=8192 seek=65536 count=557312 of=/dev/block/mmcblk0

wait about 5 min or so youll see a little pound sign when u do its done some people say to type leave and the phone will reboot but it dosnt work for me have the time so i just unplug and pop the battery. reboot and in theory you should be good to go.

now remember im on zv6 and i am rooted so i have not tested said rom and will not not losing root over testing.

if ne more info is needed just let me know.
