[Updated] upload F320L laf.img http://pan.baidu.com/s/1mUO1A

F320K laf.img http://pan.baidu.com/s/1uwwfF





Two days! ! Finally my big black brick was REPAIRED!!

Suggestion: PLEASE Read my pevious post FIRST
http://forum.xda-developers.com/showthread.php?t=2476972



My mom no longer warries about my G2 would become a brick! ! !

(Er, impatient guys can look at the red part only)

I promised in my pevious post, "If I could got my F320K brick repaired,I would write down my process in detail to help my friends stucking in the same problem"

I'm not professional, I'm just one of the thousands of G2 owner, BUT if I can help my friend out of trouble, no matter how many obstacles are there in the way, we would never give up.

Thx for all who replied my pevious post, without you, my machine is still a big brick ...
Most grateful to weiqinjun in GFAN, he gave me what i needed to repair my phone (see http://bbs.gfan.com/forum.php?mod=redirect&goto=findpost&ptid=6728131&pid=188315198 )


Well , we are now beginning


First in fastboot mode (refer to my previous post, I enter it by plugging USB into G2 with pressing the volume + ), we need to download "fastboot tool" (I posted at the end of this thread,in a 7Z file)
With this tool we can flash IMG into phone's memory partitions...


Then we need to find the corresponding img package .

I used to think of using recovery (enter method, holding the PWR and volume + for about 5 sec),but this machine seems to have a locked bootloader,unoffical recovery could not be started, But the official one have no use, pass)

Through trial and error, I found that each mode is associated with a partition (the recovery.img flashed into boot, it would start recovery automatically when booting)
So I think the download mode is related with a partition which has been lost.So i need a IMG file for this partition. . .

this time weiqinjun helped me find http://downloads.codefi.re/autoprime/LG/LG_G2
I just tried one by one. Finally, I found it. . . .

! ! ! NOTICE! The following is the method of repairing DOWNLOAD MODE:
1 get your phone into fastboot mode, connect to the computer with usb, wait for it automatically installing the driver
2 extract the 7Z file I provided into a ROOT drive,for example D:
3 Open CMD, input
Code:
     D: 
     fastboot erase recovery      [QUOTE](Note: The purpose of this step is that if flashing error, we can go back to fastboot mode by the method of entering recovery) [/QUOTE]
     fastboot erase laf 
     fastboot flash laf laf.img[QUOTE](laf.img also put in that 7Z file. This is the F320S version, My F320K version can be repaired with it without mistake, if you mind you can find your version's in [URL="http://downloads.codefi.re/autoprime/LG/LG_G2"]http://downloads.codefi.re/autoprime/LG/LG_G2[/URL] finding laf.img)[/QUOTE]
After OKAY appear, we can get battery out (IF your phone can't ,you should input
Code:
fastboot reboot
and press the PWR butten for a LONG time..till it FULLY power OFF),
get your USB cable off, then insert your bettery,holding the volume + and insert USB cable to connect with your computer...
I'M GLAD TO SEE YOU AGAIN, DOWNLOAD MODE! ! !


The operations after entered the download mode,see http://forum.xda-developers.com/showthread.php?t=2432476

Notice: This time you should flash tot file with LG Flash Tool only...refer to the second part of this and find the tot and dll file by yourself...

what about this
attachment.php


is it normal to have only B100 written inside the rectangle ?

because whenever i try to use R&D test tool to flash my KDZ file
when i press on read phone information the program becomes unresponsive and gives me a message box saying "R&D (usb or serial) not found"

i tried this on 3 different computers ...

    Here you are.http://downloads.codefi.re/autoprime/LG/LG_G2/D802/Stock_Firmware/10b_16G_partitions/laf.img

    I finally unzipped the 7z file on my ubuntu and i went and tried to flash the laf.img and it still won't work. I can't find a "fastboot folder" in my computer even when i search for it.

    This is the message that i'm getting when I flash the file:

    [email protected]:~# fastboot flash laf laf.img
    target reported max download size of 1862270976 bytes
    error: cannot load 'laf.img': No such file or directory

    help

    put the laf.img in c:\ (if c is your root) and
    fastboot flash laf c:\laf.img

    edit: What i said was for Windows. For ubuntu, right click on the file for watching the path of the file and
    fastboot flash laf path/laf.img
    You can even drag and drop the file in terminal, it writes the location of the file for you.
    So, write the following in terminal "sudo fastboot flash laf ", and drag and drop the file laf.img into the terminal and press on enter.


    Can we use the same laf for d802 32gb? 442 firmware was installed before brick
    extracts yourself the laf corresponding to your firmware (kdz) with this tool:
