fastboot flash laf laf.img
transfers the file but doesent flash it, says command not allowed, its because the bootloader is locked i guess, but still why cant i flash a stock rom even with a locked bootloader in fastboot mode?

    HI FRIENDS TODAY I AM GOING TO GIVE FULL AND EXPLAINED TUTORIAL TO UNBRICK ANY LG MODEL ( NOT SUPPORTED BY JTAG,OCTOPUS BOX)

    PROBLEM INTRODUCTION
    NO DOWNLOAD MODE
    NO RECOVERY MODE
    NO FASTBOOT MODE
    FASTBOOT MODE
    LG LOGO STUCK
    PC DETECT AS QHSUSB BULK
    PARTITION POP UP WHEN CONNECTED TO PC
    SECURITY ERROR
    KERNEL CRASH
    NO SIGN OF LIFE


    WHY MY PHONE BRICKED????????
    JUST FLASHING WRONG ROM ( MOST IN CASE OF REFURBISHED PHONE PURCHASED FROM THIRD PARTY SELLER)
    FLASHING WRONG RECOVERY
    FLASHING KERNEL
    FLASHING KERNEL
    DURING UPDATES ( FAILED OR INTERRUPTED)
    AND MANY OTHER CAUSES

    TOOLS REQUIREMENT
    LG FLASH TOOL FOR KDZ AND TOT FILE( http://forum.xda-developers.com/showthread.php?t=2432476
    (CREDIT GOES TO HYELTON)​
    TOT OR KDZ FILE ( DEPENDING ON SITUATION) >>>>>>>>>>( KEEPING BOTH FILES RECOMMENDED)​
    LG FIRMWARE EXTRACTOR ( http://forum.xda-developers.com/showthread.php?t=2600575) >>>>>>>>>>>> ( DOWNLOAD LATEST VERSION)

    ANDROID SDK SLIM mod edit - malicious link removed) >>>>>>>>>>>> ( USEFULL TO UNBRICK PHONE IN FASTBOOT MODE)

    QUALCOMM DRIVER ( http://www.mediafire.com/download/pba9wajnehr9qwg/Qualcomm+USB+Drivers.rar )>>>>>>>> ( for qhsusb bulk mode)

    PDANET FOR ADB DRIVER ( http://pdanet.co/a/)


    IF YOU FLASHED WRONG RECOVERY OR MODIFY PARTITION THEN YOU WILL STUCK IN FASTBOOT
    SOLUTION FOR FASTBOOT
    EXTRACT ANDROIDSDKSLIM.ZIP FILE ON DESKTOP ( ANY WHERE)
    INSTALL PDANET AND CHOOSE LG COMPLETE INSTALLATION
    DOWNLOAD PARTITION FILE FOR YOUR MODEL ( IF D802 THEN USE ONLY PARTITION FILE FOR D802) >>>>>>>>>> ( http://downloads.codefi.re/autoprime/LG/LG_G2)

    NOTE : 1) YOU CAN EXTRACT PARTITION FILE FROM KDZ OR TOT FILE USING LGFIRMWARE EXTRACTOR TOOL
    FOLLOW THIS VIDEO TO KNOW HOW TO EXTRACT PARTITION FILE
    2) PARTITION FILE MUST BE IN .img FORMAT ( WHEN WE EXTRACT PARTITION FILE FROM KDZ OR TOT THEN IT IS IN .bin FORMAT SO SIMPLY RENAME FROM .bin to .img )
    3) YOU NEED TO EXTRACT 10 FILES FROM TOT ( aboot, boot, sbl1, dbi, laf, recovery, modem, misc, rpm, tz ) and 9 FILES FROM KDZ ( misc file is not present in kdz so dont worry it is not important)

    AFTER EXTRACTING PARTITION FILE AND RENAMING THEM YOU WILL GET 10 OR 9 FILE ( aboo.img, boot.img, laf.img, recovery.img, sbl1.img, dbi.img, rpm.img, tz.img, misc.img) and REMOVE ANY NUMBER FROM THE NAME OF FILES ( SUPPOSE YOU GET aboot_21345.bin THEN RENAME TO aboot.img)

    NOW COPY THESE PARTITION FILE IN THE LAST FOLDER (PLATFORM-TOOLS) OF ANDROIDSDKSLIM FOLDER.
    NOW CONNECT YOUR PHONE TO PC IN FASTBOOT MODE ( OPEN DEVICE MANAGER AND SEE ON THE TOP THERE WILL ANDROID ADB INTERFACE UNDER ANDROID PHONE. IF NOT THEN CHECK ADB DRIVER INSTALLED PROPERLY OR NOT.

    NOW GO TO THE THE FOLDER PLATFORM -TOOL INSIDE ANDROIDSDKSLIM FOLDER.
    NOW PRESS AND HOLD SHIFT BUTTON ON KEYBOARD AND RIGHT CLICK IN THAT FOLDER AND YOU WILL GET AN OPTION OPEN COMMAND PROMPT OR WINDOW HERE. CLICK ON IT AND YOU WILL GET CMD WINDOW.
    NOW TYPE fastboot devices ( IT WILL SHOW YOUR DEVICES )
    NOW TYPE THESE COMMAND

    fastboot erase recovery
    fastboot erase laf
    fastboot flash laf laf.img
    fastboot reboot
    exit​
    NOW REMOVE USB CABLE AND SWITCH OFF YOUR PHONE BT LONG PRESSING POWER BUTTON
    NOW PRESS AND HOLD VOL UP AND CONNECT TO PC AND YOU WILL GET DOWNLOAD MODE FIXED
    HURREYYYYYYYYYYYYYY
    GO AND FLASH STOCK ROM ( http://forum.xda-developers.com/showthread.php?t=2432476)

    IF YOU STILL STUCK IN FASTBOOT MODE THEN TYPE THESE COMMAND ( erase all 10 or 9 file and flash them one by one as shown)
    fastboot erase aboot ( this command will erase aboot.img from phone)
    fastboot flash aboot aboot.img ( this command will flash aboot to phone )

    fastboot flash boot boot.img
    fastboot erase laf
    fastboot flash laf laf.img
    fastboot erase rpm

    HURREYYYYYYYYYYYYYY
    GO AND FLASH STOCK ROM ( http://forum.xda-developers.com/showthread.php?t=2432476)


    SOLUTION FOR ALL THE PROBLEM WITH NO DOWNLOAD MODE
    YOU NEED TO FORCE PHONE INTO QHSUSB BULK MODE BY SHORTING TEST POINT
    WHEN YOU GET QHSUSB BULK MODE IN DEVICE MANAGER THEN INSTALL QUALCOMM DRIVER ( http://www.mediafire.com/download/pba9wajnehr9qwg/Qualcomm+USB+Drivers.rar)

    NOTE : THERE ARE TWO MODE IN QHSUSB BULK
    1) QUALCOMM HS-USB 9006
    THIS MODE IS VERY EASY TO FIX. YOU NEED THE PARTITION FILE THAT WE GET IN THE STARTING TO SOLVE FASTBOOT MODE)
    TO SOLVE 9006 FOLLOW THIS METHOD ( http://forum.xda-developers.com/showthread.php?t=2582142 )
    UBUNTU METHOD IS UNIVERSAL IT CAN BE USED FOR ANY PHONE IN 9006 ( UNBRICK VERY PARTITION METHOD ( http://forum.xda-developers.com/lg-g2/general/unbrick-lg-g2-qhsusbbulkqualcomm-9006-t2939627) BY TUNG KICK IS ONLY FOR G2 HOWEVER IT CAN BE USED FOR GPRO2 AND G FLEX BUT I M NOT SURE IT MAY NOT WORK OR BRICKED MORE)

    WHEN YOUR PHONE GET STUCK IN 9006 THEN LOTS OFF DRIVE POP UP WHEN CONNECTED TO PC ( MOST IMPORTANT IDENTIFICATION)


    2 ) QUALCOMM HS-USB 9008
    IF YOU STUCK IN 9008 THEN THIS IS THE SUPER HARD BRICK MODE.
    CONTACT aftabalam8c2 ( http://forum.xda-developers.com/member.php?u=4554553 ) this guy not only can unbrick lg g2 , g3 but g pro 2, g flex, vu3, vu2, nexus4 , nexus 5, lg g , lg gpro, and around MORE THAN 30 ( I DONT KNOW BUT HE TOLD ME ALL HE CAN UNBRICK MORE THAN 50 ) devices of lg which not supported by JTAG OR OCTOPUS BOX.

    ACCORDING TO HIM MOST USER DAMAGED DURING SHORTING OF TEST POINT ( SO BETTER TO ASK HIM BEFOR SHORT)
    I NEVER SHORTED SO DONT ASK ME. HE ALSO MADE A SERIES OF TEST POINT ON YOU TUBE FOR MANY DEVICES BUT THESE VIDEO ARE NOT PUBLIC NOW. MAY BE HE MAKE ALL VIDEOS PRIVATE AFTER SOME GUY CHEATED HIM ON XDA ( CONCLUDED FROM HIS COMMENTS)

    AND THE ACCOUNT OF THIS GUY DISABLED BY XDA FOR 1 WEEK ( I ASKED HIM PERSONALY ON WHATS APP)

    SO IF YOU WANT THE TEST POINT FOR ANY PHONE ASK HIM​
    .

    THIS GUY UNBRICKED MY LG G FLEX IN 20 MINUTES IN FRONT OF ME ( WE ARE FROM SAME STATE SO I WENT HIS HOME)
    FO THE FULL STORY OF LG G FLEX UNBRICKING SEE THIS ( http://forum.xda-developers.com/lg-...nload-mode-t3059257/post59555140#post59555140)

    SO THE MOST IMPORTANT THING IS TO SHORT THE TEST POINT CORRECTLY WITHOUT DAMAGING EMMC ( I WOULD ADVICE ALL OF YOU PLEASE ASK HIM BEFOR SHORTING MAY HE SHARE THOSE VIDEOS ON YOU TUBE )
    FOR COLLECTION OF TEST POINT SEE THIS ( http://forum.xda-developers.com/hardware-hacking/hardware/collection-test-phone-t3048736 )

    SOLUTION FOR ERROR DURING FLASHING
    FOLLOW THIS GUIDE ( http://forum.xda-developers.com/lg-g2/general/lg-g2-cross-dll-device-model-fota-laf-t3003717 )

    THERE ARE MANY GUYS WHO CLAIM TO FIX YOUR BRICKED LG PHONE BUT I DONT KNOW THE AUTHENTICITY OF THESE GUYS
    TUNGKICK WHICH IS ALSO WHO UNBRICK HAS VERY BAD RECORD, I SEEN THE POST MANY GUYS CLAIM THAT HE STEAL PASSWORD AND DATA FROM THEIR PC AND TOOL HE USED INSTALL KEYLOGGER TO YOUR PC ( I AM JUST TELLING THE COMMENTS ON GUYS AND THEY ALSO UPLOADED SOME PIC FOR THE PROOF)​

    How I bring back my G3 F460 from Death

    Hello, I'll explain you all how I recovered my LG G3 F460K from death, I must first thank @Kathik and @Vega_Kangmin for their guidance, tutorials and files, without them I would not have been able to recover my phone, the steps are basically as they are explained in Vega_Kangmin´s tutorial:

    http://forum.xda-developers.com/lg-g3/general/unbrick-debrick-f460-boot-security-t3352382 -----> Thanks to Kathik

    http://m.blog.naver.com/kangmincraft/220675995736 -----> Thanks to Vega_Kangmin

    However, I found some differences that stopped me so I had to read and research in Google to make decisions and to continue with the process.
    These are the steps that I follow:

    1. Download all programs and files suggested in Vega_Kangmin´s tutorial.

    2. I extracted the files from the original KDZ Lollipop (F460K20C_00.kdz) and put it in the folder that I call “ADB”. (My G3 had the Lam Hoang 1.6 Android 5.0.1 Rom and was rooted with debugging enabled).
    3. With the Win32Disk Imager I make the first boot image to use in the phone with a microSD card, first I try with the debrick image called “debrick140.img” and the screen did nothing, unanswered. Then with the win32Disk Imager I created the image boot with 160MB and bingo!! It works!!, the screen showed the LG logo and immediately fell in Fastboot mode. Here I tell you my first warning: the only microSD card that I have was a 32GB Class 10, so I used it, then the win32Disk Imager program created in it a new partition table and reduced the 32Gb capacity only to 85MB, so after I had saved my phone, I have to save my microSD card, for that, I used Ubuntu, and one program called “Gparted” I uses it to redefine the partition table. So, beware!!!

    4. I opened a CMD´s window in the folder "ADB" (shift + right click, click on "open a command window here"), plugged my phone in the PC (Windows installed the drivers of ADB interface and immediately it recognized) and I wrote my first command to verify that everything was in order:

    fastboot devices

    If all goes well it should show up this:

    List of Devices attached
    LGF460XXXXXXX device


    Then I proceeded with the ADB commands, but in the tutorial I found some errors in the syntax of the commands and the order they should be done, the correct syntax is:
    To remove files the syntax is ok, example: fastboot erase aboot
    This is the syntax to flash new files is: fastboot flash aboot aboot.bin

    (Don´t forget to change names of the extracted kdz files)

    And the order for all the process in the ADB pront is this:

    fastboot erase aboot
    fastboot flash aboot aboot.bin
    fastboot erase boot
    fastboot flash boot boot.bin
    fastboot erase laf
    fastboot flash laf laf.bin
    fastboot erase rpm
    fastboot flash rpm rpm.bin
    fastboot erase recovery
    fastboot flash recovery recovery.bin
    fastboot erase modem
    fastboot flash modem modem.bin
    fastboot erase SBL1
    fastboot flash SBL1 sbl1.bin
    fastboot erase tz
    fastboot flash tz tz.bin
    fastboot erase sbi
    fastboot flash sbi sbi.bin
    fastboot reboot
    exit


    Note: none of these files should be used BackupGPT.bin, PrimaryGPT.bin (if you use it the ADB will return an error saying that these tables do not exist, the file misc.bin neither will use because we do not have it and it isn´t important to revive the G3, this information I got it from here:

    "YOU NEED TO EXTRACT 10 FILES FROM TOT (if you use a tot file) (aboot, boot, SBL1, dbi, laf, recovery, modem, misc, rpm, tz) and 9 FILES FROM KDZ (this is our case for the Lg G3) (misc file is not present in KDZ so dont worry it is not important) "

    That out of here, please read it:

    (Thanks to @hacklockx)

    5. After restarting the phone it show up the LG logo (this is a good news), so flash an official ROM with the LG Flash Tool as you already know and enjoy our super phone again.
    By the way, in my case, after the process restart with the ADB commands, my phone start normally with all my stuff installed, I lost nothing, as if nothing had ever happened, however, I noticed slow and the camera didn´t work so I flash it with the official rom F460K20C_00.kdz and it was like new. Then I rooted it, installed the TPWR and flash again the Lam Hoang 1.6 ROM with Android 5.0.1, then installed the Xposed and that´s all!!

    I hope you serve!!
