[G3 General] Kathik:
Dead, Unbrick, Debrick F460. Dead/boot security error/boot loop kitkat,lollipop version bootloaders, 9006, 9008 modes

FIRST install lg united mobile drivers, connect mobile with battery to pc, check in device manager com ports if 9006 or 9008 mode.

if you can go into custom recovery mode twrp/cwm, then it easy to fix... u need to flash zip.but your self have to make it right now of same version. here the link tutorial.. http://xdaforums.com/showthread.php?t=2451696 OR try adb or terminal command or u need to make zip file. i lost that link. better try ubuntu method also.

CASE1:

if 9006 or 9008 mode, ROOTED,on lollipop/kitkat/marshmallow before phone dead but rooted, first try debrick sdcard which is simpler, then use ubuntu method. this works only if rooted before phone dead. only root access allows to rewrite files on partition here is the link http://xdaforums.com/showthread.php?t=2582142

CASE2:

only 9008 mode, phone dead on lollipop/kitkat/marshmallow, not rooted, then try debrick image and Ubuntu methods. sucess rate is very low.

Guys!

the sdcard debrick may success. then these files can debrick it.

OUr devices can be fixed. After lot of research i found it. kindly go through the link given below for tutorial and do debrick. You need to try from 140 to 220. hope YOU THANK ME HERE is the Link http://m.blog.naver.com/kangmincraft/220675995736

Read this post who unbricked his dead mobile http://xdaforums.com/showpost.php?p=66264994&postcount=14

just poweron the device after inserting the sdcard. check few times. try to go download mode.

use google translator if needed.

TIPS

sdcard miniumum 4GB, use old sdcards first. then latest memory cards, try sdcard memory higher than phone memory is advantage. try these 3 types.

debrick140 worked for most of them. try this first if you are on lollipop.

Lollipop bricked roms have higher luck.

after successful unbrick, use poweriso/ultraiso to format sdcard. i used poweriso>tools>cleanusb. then format in your pc.

ATTENTION MARSHMALLOW: IF YOU NO ROOT, NO CUSTOM TWRP, NO DOWNLOAD MODE. THEN THERE IS NO DEBRICK IMAGE YET. NOTHING WORKS. GIVE TO REPAIR RIFF,OCTOPUS BOX.
