LG Leon(MS345) - Need Stock LAF.img & Diag Mode - LG Leon Questions & Answers

LG Leon(MS345) - LAF.img & Diag Mode
Hello,
FIRST
I am currently working on unlocking a LG Leon MS345 from MetroPCS. Somewhere along my journey I tried a thread(From another site) which suggested an unlock method by zero-ing out the LAF partition and placing a different img there. It was unsuccessful and a complete waste of time.
I was wondering if someone could dump the stock laf as now I have no download mode. Also, if possible provide some information on how I can repair/replace my download mode.
Second
I am trying to get this phone into Diagnostics mode. On stock ROM this was easy by accessing hidden menus via shortcut master(w/ROOT). I am currently running the CM12.1 Unofficial on my device. I have not figured out anyway to get this phone into diagnostics mode on the CM ROM. Any suggestions?
I have several days of research and trial/error into this phone. To continue my testing I must fix one of the two problems(or both) listed above. Any help is greatly appreciated.
Thanks,
Drew

You can only try to get your kdz file, extract contained files, take the file that you need, change the extension from BIN to IMG and try with terminal emulator to replace the files. But you need to know which mmcblk you should replace. This would be easier if you boot into Linux and try to access these partitions from it. I don't know how to do it. I'll provide some useful links if I don't forget about helping you out.

Lg g2 hard brick fix

For everyone with a lg g2 stuck in either the fastboot screen
I had the problem myself an was able to recreate the problem a couple times, can't post any links because I'm new on here. But this is the fix download the stock 4.2.2 zip cmw/twrp friendly one not the one containing the .tot file an extract the entire zip or use winrar to navigate to the boot image an extract it.
Flash the boot image, this will allow you to reaccess download mode and or recovery if you have one installed need anymore help pm me. Also on a side note I couldn't find a working adb driver for the g2 maybe it's just bad luck or lack or research but I was able to get adb fully working with two diff drivers.
1 the adb drivers for the HTC one don't ask me why an minimal abd and fastboot drivers worked as well.

Dead,Unbrick, Debrick LG G3 F460 S/K/L. boot security error, boot loop, dead mobiles

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://forum.xda-developers.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://forum.xda-developers.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

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.

hi manowar.
you can solve the problem with using debrick.img files.
go to the link and solve the problem!
Hello Vega and Kathik, I have not done the process yet, I will do it tonight, and then I will inform the results.
I also wanted to thank you for the hard work you are doing in publishing this tutorial and translate it into English, I know you're still working on it, but so far it is understandable and looks promising.
I have some questions to you, to clarify the process that will perform tonight, please, answer me this:
I just have a 32 GB microSD Class 10, does this serve? Or it is too large in capacity? (By the way, my Lg G3 F460K is 32GB of storage and 3GB of RAM, it has Android Lollipop 5.0.1 with HOANG LAM CAT6 1.6 ROM and it was rooted)
When I will do the format to the microSD card, before passing by the win32Disk, what format I give it? ¿FAT32 or NTFS? Or the Win32 software do it for me when it will formated the microSD?
After inserting the microSD prepared, simply press the button on/off on the phone? Or I must do any combination of on/off + vol + or any other?
It is rare to found any solution for this korean model, there are only solutions for the international models, but it seems there is nothing for the Korean model (F460L,S,K). I hope that this work will help many people in this situation and prevent all those who are paying for solving this problem.
Please brothers, answer my questions and I will do the rest. Many thanks!!!

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://m.blog.naver.com/kangmincraft/220675995736
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:
http://forum.xda-developers.com/android/general/unbrick-lg-model-download-recovery-t3060184​ -----> 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!!

Try these options:
1. Change your battery, try another one, in my case I have two battery, one cause endless bootloop on my G3.
2. Use the "LG Mobile Support Tool", install the program, open it, connect your G3 and see the magic happens :good:
Good luck bro

How to fix very bricked LG V20 from bad rooting?

jeanclaudevandamme said:
Right, I've figured out where things have went wrong but still can't find a fix
1) So after Step 14 after running the BAT files all cmd windows closed. I then clicked step3.bat while in fastboot mode. because he did not explain clearly where you were supposed to get CMD window for commands in Step 16.
I had used CMD / ADB / Fastboot years ago, but I had forgotten how they worked exactly, as the instructions for the previous phones I have rooted were so much better written.
later i discovered how to see what was inside a BAT file (use notepad to open it) so step3.BAT contained instructions to flash "boot1.img" which came with the Dirty Santa v20 files. I don't know what model that boot image was taken from. it also contained instructions to flash a twrp file name that didn't exist (so I guess nothing would have gotten flashed).
2) later I was able to launch into fastboot mode and manually flash the correct twrp file onto the phone. then led me being able to get into twrp recovery to flash kernel + SU.
However phone still didn't boot, presumably of the mistake was previously by clicking Step3.BAT, which flashed a "boot1.img" from dirty santa files
Also when going into download mode, the phone would crash with static 1 second after connection.
3) At the time, I didn't know the difference between aboot and boot files. So I went into fastboot and flashed abootbackup.img
I still don't know fully what aboot does. But the effect it has is it locked the bootloader, so i am no longer able to flash anything with fastboot. writing the old aboot.img has caused my device to go into a corrupt bootloop, cannot launch into recovery.
I think that if I flashed bootbackup.img then things might have worked out ok. i had 2 choices and I picked the wrong one, but that's gone now.
flashing the abootbackup.img also had another effect, download mode no longer crashed with static after 1 second, however a new error code came up when download mode is launched <633A B50>, the phone acts like a firmware is currently trying to be flashed but stuck at 0% even just by launching download mode.
I'm guessing there may be some sort of variant mismatch between the boot1.img and the abootbackup.img as the boot1.img wouldn't have originally come from my phone? As well as the other stuff pushed onto device in Step2.BAT
eithe way, LG Bridge / LGUP do not recognise model even with Uppercut.. LG Flash 2014 has the error messge of "connection to server failed", I tried letting it run in the background without closing error message as suggested in that thread, but I guess because of my 633A B50 error message, flashing did not occur in the background like other people.
----------------
I don't know where to go from here exactly. because
1) boot1.img, that came with dirtysanta files, which model / variant did it come from?
2) what LGUP_common.dll will recognise my device now? I know someone patched their DLL, but how do you patch a DLL using hex editor and how to make the DLL recognise my presumably mismatched device?
3) i don't know what the <633A B50> error message means exactly

It's more bricked than usual..
Have a go at this?
I like using the LGUP Patched DLL for H91810J. It seems to recognize all variants.
as a last resort use LG Bridge, refurbish. it will repair all sorts of half installs and messed up partitions. the only thing is : IT WILL BRING YOUR BUILD UP TO 10q=================WHICH IS NOT ROOTABLE!!======================
Just in case this issue has not been resolved. I did the same thing 10 minutes ago. I flashed the wrong abootbackup.img (10c) instead of 10d.
All you have to do is open LGUP and if the device won't be recognise, just run the Uppercut tool and the device will show up. Flash your .kdz file and the phone should be running once again.

Can't find kdz file for LGH918 (T-Mobile LG V20)

I'm trying to find the latest kdz file for the H918 (T-Mobile LG V20). After looking at several guides, I still can't track it down.
This guide gives a link where you can supposedly download the firmware, but all I can find by following that guide is the Android source code, not a .kdz file.
This guide gives a url you can visit (on a non-standard port), and you have to put your phone's IMEI number in the URL parameters. This url will return an xml file that contains another url where you can download the kdz for your specific phone. However, when I followed this guide, the xml file returned a successful response but the sw_url field was empty (along with most other fields).
Other guides have said to go to https://lg-firmwares.com/category/lg-series/lg-v20/ but I am getting a 500 server error on that page. Maybe it's just down today, but seems kind of odd that I can't access it. When I try to find LGH918 by visiting the main domain name (lg-firmwares.com) and navigating from there, I can't seem to find anything.
The closest I have come so far is this download page, but it is for the LGH918TN (instead of LGH918). Is that "close enough" or is it going to brick my phone?
UPDATE: I think I did find the correct kdz file since I started writing this post, but I am going to post this information anyway, for anybody else having the same issue. I went to lg-firmwares.com and clicked "Check IMEI" and entered my phone's IMEI number. It directed me to a download page for LGH918TN, so it looks like that is correct for my phone! I will try and remember to report back here on whether the kdz file actually worked or not. Hoping it doesn't brick my phone, yet again.
As an update to my original post, I did manage to successfully flash the kdz file using the "Upgrade" option in LGUP, and did not lose any of my data. However, I'm still getting the unlocked bootloader message when I start my phone ("Your device cannot be checked for corruption..."). Does anybody know if flashing the .kdz file causes TWRP to be replaced with the original recovery mode? I don't want to try to boot into TWRP in case it has been replaced, thus triggering a factory reset and losing all my data.
It ok to try and relock the bootloader now? (if so, how?) Or do I need to replace TWRP too?

You need to use LG Bridge to restore to stock. That will replace TWRP. Then you need to fastboot OEM lock.
If you don't want root and want to relock the bootloader to stop seeing that screen, you will lose data.

LG G4 H81520p bootloader unlocked, Download mode avaliable, cant flash anything

Hello everybody. Im asking for help and im pretty desperate for my issue.
I have LG G4 h815 20p which was rooted few years back. Then the phone died and got re-balled recently and it works now. But i can not access twrp by using Volume Down and Power buttons combination. I can go to Download mode where i can updated firmware using LG UP and it will be processed to the end and after the required reboot phone stays black and recognized only as qualcom device in device manager.
I can not use ADB as it will never show any devices under adb device neither fastboot devices. Drivers are installed. Tried bunch of different versions on both win10 and win7 but no luck. I also tried installing those on ubuntu, where the phone is seen as a device under lsusb but not under fastboot or adb.
I just want to get the phone up and running. NO matter if i unroot or keep it rooted. It wont be used as daily phone but im eager to fix it.
The phone lists bootloader unlocked on the top of the screen together with LG logo and then comes the android robot animation for 3-4 seconds then loops the same 2-3 times then goes black screen (shows as qualcom device in device manager).
Tried LG UP, LG flash tool neither helped. LG Flash tool wont even end as LG UP finishes but wont boot after the reboot when process is completed.
Any help please will be extremely highly appreciated. I am also willing to arrange team viewer if necessary for easiness.

Boot to fastboot and exec
fastboot format userdata
(will obviously erase the whole device including photos etc)
If that does not help you can use SALT to flash TWRP to the BOOT (!) partition. For that you must start SALT from the cli with --experimental argument. If you plan to use SALT I recommend using the latest mAid njghtly which has all already installed.
For flashing with SALT you also must do a custom backup of the sbl1 partition and place the twrp image in the same dir where the sbl1 backup is.

Hey, Thank you.
I found your stuff uploaded, but i really cant figure it out. Whenever i press Volume UP and Power button to keep them 6-7sec then plug usb cable, the phone misses the chance to go into download mode. So i have no opportunity to go into fastboot. But i can go in download mode but neither fastboot or salt finds the device.
Could you please provide some more info?

fastboot and download mode are complete different things. you cannot use fastboot commands in download mode.
you have to provide more info:
how do you run mAid? VirtualBox or from an USB stick (recommended)
share the debug log of SALT when your device is in download mode (Advanced menu -> debug log -> upload button -> share just the link)
boot your device in download mode and THEN start mAid first could also help

Hello again.
I figured mAid out. I run from live usb, and i can connect to phone and get the device information through Salt..
What i did:
- i use experimental flag with root privileges and device is read and comes info that my Laf fw does not support direct flashing. (i cant figure it out how this works),
- i made backup of sbl1 partition, downloaded twrp image twrp-3.3.1-PREVIEW-196_g4_MM.img, placed the twrp image in same folder where the backup of sbl1 is.
- Now i dont know how to flash the the twrp to the boot partition. I tried to find some guides but no luck. Yesterday for some reason i had Flash button in salt on the bottom, today it is not there. The way i start salt is by browsing inside /home/android/Desktop/LG directory and use sudo ./SALT.desktop --experimental command. I use the latest mAid from your file server 4.19.126-1-MANJARO - mAid_v2020-07-14_23-43_x86_64_forgetful.iso.
3 attachments are uploaded bellow. The debug log from salt was unable to upload and gave bunch of package errors, so it is attached bellow in a txt file as well.
The phone keeps stable connection in download mode.
Please advice. I am very grateful.

you start SALT in experimental mode as this in a terminal:
Code:
~/programs/SALT/salt --experimental
anyways the problem is that your LAF version is 100004 so flashing will likely not be possible.. You can try it anyways by using the above cmd which will bring up the flash buttons.
before doing that rename the twrp image to recovery.img to ease up things.
then you select flash (folder) and ensure that anything else then the recovery image is selected (e.g. do not flash sbl1 etc).
also ensure that the target partition is named "recovery" then choose flash.
as said it will likely not work though as your download mode (LAF) is too new though. you could downgrade with LGup to Lollipop which will allow flashing with SALT for sure.
but back to the initial description, you mentioned that:
[...] after the required reboot phone stays black and recognized only as qualcom device in device manager.
[...]The phone lists bootloader unlocked on the top of the screen together with LG logo and then comes the android robot animation for 3-4 seconds then loops the same 2-3 times then goes black screen (shows as qualcom device in device manager).
These indicates very very likely the beginning of the ILAPO. you can check my signature for some workarounds though there is no proper way to fix it other then by replacing the mainboard.
