[G4 Q&A, Help & Troubleshooting] gratefuldeaddougie:
This is my universal LG 90 minute method to virtually unbrick the most stubborn of bricks. This dilemma concerning the Verizon varient not getting any unbrick love has been making me ill. Let us, with the VS986_9008's, take the QDloader to the Mortal Combat ring And show it the "9008 Fatality". This takes about 90 minutes and sheds an unbelivable amount of light on a larger scale. I am starting this thread due some "lurkur guilt". I've been silently creeping around XDA since 2012. Not a single THANX button, post, comment, or even regerstering a user name. I have gathered all the things to revive this device here on XDA. So there is no need to go anywhere other than download mirrors provided by authentic XDA members. Well. First. Along over due shout out to the Devs whom I owe appreciation to, and they don't even know it yet. This is a long list. THE Greatest of THANX & PRAISES to GameTheory, PlayfulGod, Mazda, Steve Kondick, ChainFire, LaserWolf, roirrawdaor, RootJunky, Roark 13, and many more. Most importantly the main body of the Xda Developers that work painstakingly consistant on keeping these forums spam and malware free. Thank You for all the patience and for the most part, compassionate and keeping the sarcasm down to a minimal when dealing with noobs' questions at times when all any body ever wanted was a greater understanding of the Android OS. It displays a level of understanding and Professionalism that is so scarce in this technological revolution era. Never a noob joke. Very Cool. So very, very cool. I have never done this before so here goes........ One more thing be fore we start. I will not be providing download mirrors, links, or subsections of instructions on how to use these tools. I am leaving the greater portion of the learning curve to the reader. Big Tip: Search Plus is your greatest friend. Drum Roll Please.......................................................................................................................................................................You will need these 1) VS98627C_00_ARB02.kdz

2) VS98613B_00_ARB02.kdz 3) LGMobileDriver_WHQL_Ver_4.2.0.exe 4) QHUSB drivers (Qualcomm drivers) 5) QFIL (latest version) 6) WindowsLGFirmwareExtract (latest version) 7) LGUP and 8992_dll.msi (LGUP for G4) 8) LS991_ARB_02_RecoveryImage.zip (Yeah. I know it's for sprint. Just trust me.) This is done in stages so maybe a small break to stand up and stretch in between each phase is a protocol to follow. FOR SANITY. PHASE ONE: When all the needed files are chill'in on your desktop create a new file and name it "VS986 Firmware Recovery" extract the LS991 RecoveryImage to it. Now delete these laf, tz, pmic, rpm, hyp, sdi, sbl1. Using WindowsLGFirmwareExtract ; extract the VS98627C.kdz . We now take the VS98627C laf, tz, pmic, rpm, hyp, sdi, and sbl1 files and move them to our "VS986 Firmware Recovery" folder. Last but not least rename the file extensions of those from bin to mbn. But do not rename the laf.img file. Congrats. you just made a recovery image for the verizon varient of the G4. If you didn't Know how to use the kdz extraction tool. You do now. Isnt learning Android a Blast. PHASE ONE COMPLETE PHASE TWO: Like I said in the begining.. I am not giving Tuts on the use of tools or driver installs. - Iinstall the LG drivers / install the Qualcomm drivers / install LGUP and 8992_DLL.msi / Reboot PC / Go Pee PHASE THREE: Open up the back of your G4 but leave the board intact in the chassis. If you have never done this before then I suggest a youtube search to get you up to speed. With the phone open and your PC freshly booted, open up DEVICE MANAGER and force the G4 into QDLOADER 9008 mode using the test points. Again there are more than enough Threads on this topic. Open QFIL Double check the comm port number in device manager compared to comm port connection in QFIL. Make sure they are the same. IF QFIL does not recognize your connected phone than driver installation school should have held you back for that lesson. When you're all good up to this point....... Tick the "FLAT BUILD" box............. load "prog_emmc_firehose_8992_lite" found in the folder you created................. rawprogram0.xml and patch0.xml should load automatically. If they do not then load them manually. Click DOWNLOAD button. This should result in a successful flash of the laf image, except in the case where the device has the dreaded G4 hardware curse. If the logic board has no issues there should not be a problem. Upon success/pass of flash, disconnect the phone from the PC and put back together you device. PHASE 4::: This should be easy. Hold volume up. Plug into PC. Continue to hold volume rocker up untill FIRMWARE UPDATE screen displays. Use LGUP to flash the VS98627C.kdz and if you like downgrade to 13B for root and start all over. What do you mean to tell me you are not familiar with download mode? What in tar nations are you doing here? Did you try the SEARCH PLUS feature?
