Although it has not been tested, there is no reason it shouldn't work. The worse that could happen is you're stuck in the same situation.
Firehose exists for g6 now? Would this allow me to safely pry at LG's bootloader without permanent bricks? Would love to take it into my own hands but couldn't afford the risks before. I'm using a Canadian H873

Yep. Have at it. But, like always, I don't recommend purposely bricking.
I should mention that you don't need to use the xml stuff.
In QFIL in one of the top menus, there's a partition option, where it reads the gpt from the phone and you can select them and flash individual files. So you can flash directly bootloader
or whatever you need from your proper kdz source.
Lot's of people have wrecked there partition table trying to unbrick. That is why I included them.

Did you try it yet?
I'm also trying to fix a dead Canadian H873 (Videotron Carrier). Had tried my hand in the past at creating the patch.xml and rawprog0.xml (one method had me peek at the gpt files using an excel/libreoffice spreadheet) but failed for various reason also not having a proper programmer file didn't help any.
For those that encounter issues with either the programmer file failing or getting sahara fail FHLoader, something like cannot find system file try this:
1. Make sure to reboot phone and hit download to phone in QFIL right away. On my device sahara seemed to be timing out quickly.
2. For the second error using the QFIL included with QPST 2.7.474 fixed it.
Sadly i tried to refresh the phone using the backup files i was given with it but now it doesn't get detected. Holding power button the phone vibrates and nothing else happens. Tread lightly.
So good news the programmer file works (tried it on a H873 Videotron variant), bad news do it right the first time or else.
Time to start searching for a way to force it back into edl.

To clarify i used a backup of the files i had on hand for the device and not the files provided by OP.
Hi everyone, I have just bricked my G6, hard brick I think ( does not charge, cant get into download mode, cant hard reset either, only show Qualcomm qloader 9008"). This happened after I tried cross flashing it from LS993 to H872 ( I now know that a NO NO ). Can someone here help me on how to get it back to life ? I ve read quite a lot of different topics but the more I research the more confused I am. Some say I need to restore to stock firmware, but there is no stock firmware for LS993... Any help would be greatly appreciated and I hope you have a very great day
Read my method, download the files, read it again, and follow the steps.

I bought a LG MyTouch 4G Slide (myTouch Q)
I rooted it, upgraded the software, everything was great.
I was flashing a theme through zip and suddenly, it cut off and now my phone is unresponsive.
The LG splash screen shows twice, followed by displaying the following message:
E:Can't find misc
E:Can't find misc
Finding Update Packages..
E:unknown volume for path [SDCAR
D:/download/(name of the zip file)]
E:Can't mount SDCARD:/(File location)
Installation Aborted.
Factory Reset Failed
Restart Factory Reset
Then the cycle repeats its self.
I cannot access bootloader (power+volume down) no matter how many times I try, it continues to do the same process.
I have searched everywhere and cannot find the answer to this problem, does anyone know how I can make my phone work again?
how'd you upgrade the software? try loading a stock rom either through your computer or sd card, I'm not familiar with the exact process for a slide, but that's what I'd try.

I did it the old-fashioned way. Went into settings and searched for updates, then T-Mobile updated me OTA.
The phone worked perfect prior to the theme.
Every file I've put on the sdcard seems to not have any effect on this problem.
Do you know where I can find a stock ROM for LG M4GS? All the one's I've seen around are for HTC.
I downloaded ODIN but it only tells me to connect the phone when it's plugged in via USB.
I'll donate to whoever helps me, really need to fix this issue.
how'd you try to flash the theme? through a custom recovery?
and why did it stop?
did you give hard factory reset a try? (dunno what exactly it resets but it might help, and it might actually be exactly what your phone is trying to do according to the screen output):
http://forum.xda-developers.com/showpost.php?p=20310765&postcount=8
if that does not work, try to at least get some more logcat:
install the android sdk, plug your powered-off-phone into usb, run:
adb logcat
it should start the service and be:
Code:
- waiting for device -
then power the phone and post the output...
good luck
Questions should be asked in Q&A forums, not Development forums.

Attached is a screenshot of the error I receive everytime.
The phone does not stay powered off when USB connected, keeps trying to boot.
After two splash screens, the error screen shows.
I used SDK to obtain the screenshot, but none of the other tools seem to work.
Below I have attached the screenshot.
so did you try the hard reset?
if you did, can you get into recovery mode (supposed to be A [QWERTY] + F [QWERTY] + Vol Down + Pwr) or s/w upgrade mode? (E [QWERTY] + Vol Up + Pwr)
if you can get into either one you're probably ok.
through recovery you can flash whatever, and through s/w upgrade you can use a tool called LG Mobile Update Tool (you wrote about odin, which is a samsung tool for samsung phones. this is apparently the lg equivalent):
download the original 2.3.6 firmware here:
http://forum.xda-developers.com/showthread.php?t=1825818
and do what they say here (its for the mytouch 4g but i guess the process is the same. you might wanna read up on this a bitbefore you do it):

I looked every where for this and hope it does not violate any rules - but wanted to repost so that it might help someone else. Again if it is a violation then I apologize but was just before returning to LG for repair.
If you have a tmobile prepaid LG c800 ( may work with contract phone not Sure) this should un brick your phone. I am not the author and take no credit it came from here :
http://androidforums.com/mytouch-q-...-progress-porting-custom-recovery-over-2.html
1: Download and install Drivers from LG site Mines is C800VL. http://www.lg.com/us/products/documents/LG_OSP2.0_Setup_2.0.07.20111130.exe
2: Download and install LGMobile Support Tool leave open i read it is needed to flash. http://csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
3: Download the .kdz file Its for C800DG but works for C800VL , C800VL don't have a kdz file at least i don't know i looked every where. V10D_00(C800DG).kdz - 4shared.com - online file sharing and storage - download
4: Open LGMobile Support Tool leave open.
5: Download the Flasher from post one
http://androidforums.com/attachment...s-porting-custom-recovery-over-updater-2-.zip unzip and install msxml.msi included with zip
open KDZ_FW_UPD.exe set to 3GQCT - Smart Phone(WM)
browse for KDZ file (V10D_00(C800DG).kdz)
click lunch software update and you should be in S/W Upgrade mode wait for program to finish if it errors leave phone in update mode and click lunch software update again.
One note make sure to download the correct version, there seems to be several the "LGMobile Support Tool"( file name "B2CAppSetup.exe") one will take you to the LG site and do an automatic update and tell you that your phone is not supported and to contact LG and the - "KDZ_FW_UPD.exe" it will be the one with the "browse for file" on the opening screen, also not sure but on another web site it said to use windows enabler file V 1.1 it will run on the task bar at the bottom as an Icon of the seperate windows tiled, click on this so that it says"on" not postive it is necessary but this how I ran the KDZ file. There is a V10V kdz file but it would not work on mine.
Update: after flashing with kdz - V10D_00 (2.3.4) Reflashed/updated with kdz V10v (2.3.6) would not upgrade OTA or at the lg site.
REMEMBER: DO THIS AT YOUR OWN RISK..DO FOLLOW STEPS SO THAT YOU WONT ENCOUNTER ANY PROBLEMS.!
Thinking that your phone is bricked??

*Don't worry your device is not fully bricked.. There are many ways to fix this..
*Before proceeding please make sure your phone is charged even if the backlight is always on while charging..
* Remember make sure LG UNITED (Driver of your phone) is already installed (to avoid PHONE WAS NOT FOUND)!!!!!!
*This will restore your Original Rom.
*This Works On All Variants Of Optimus One (LG-P500,LG-P505,LG-P506,LG-P509) and other few devices
*For the Prerequisites (Below)..
Prerequisites:
*KDZ Updater/Lg United
*Windows Pc/Usb cable
INSTRUCTIONS:
STEP 1:Download the prerequisites. Disable all LGE modems under modems from Windows device manager in
the control panel.. (Simply click start then type ''Device manager'' click it. then you will see there under MODEMS)
STEP 2:Exract the files..Open the KDZ Folder to your desktop and Right click on the "KDZ_FW_UPD.exe" and
click RUN AS ADMINISTRATOR.
STEP 3:Open the "Original firmware" folder and run it, type the serial number on the blank form entry. You can
Find you serial number on the back of you phone, remove the battery and look for the sticker attached to you phone.
If you fail to launch this software, you will have to install net. framework 4.0, just open your browser and type
NET.framework 4.0. Download it and install. After this you are able to run the software.After you type down the serial
number of your device click save and just save it on you DESKTOP. Wait until it is finished. This takes some time.
Internet connection needed as this software is downloading the ''KDZ file'' needed for the "KDZ_FW_UPD.exe".
STEP 4: Now lets go to your phone,press and hold both the back(return) button and the volume up button and
simultaneously connect the USB cable.. (The phone should light up and say Emergency mode!! in a green

First, this method should work for all Optimus One variants. P500, P505, P506, P509, and a few others
Second, a couple corrections, if you don't mind...
Step 3: ... type down the serial number... This is incorrect. This should be IMEI number. IMEI and Serial are two different things.
Step 4: ... Emergency mode!! in a green background... Emergency mode has a Yellow background and "Emergency Mode" printed on the screen in Red.
Third,
When something goes wrong, the device will first attempt to boot to recovery. If it can't boot to recovery for whatever reason, then the device will reboot to fastboot mode. From here there are other options, not just KDZ. KDZ should be the last line of defense as it has bricked many Optimus One's and it's variants. If the device drivers had been previously installed correctly to a Windows PC, then fastboot.exe or any GUI tool for fastboot.exe can flash a recovery that can then be used to repair/replace the device's OS. Linux/Unix users don't need drivers to communicate with USB devices, only a 51-android.rules file and a fastboot executable for Linux/Unix.
Don't take what I've said the wrong way. I'm not trying to shoot your guide down. This is the kind of activity that is encouraged at XDA not discouraged I just wanted to inform you that there are other options.
Thanks a lot. You really saved my phone. Worked like a charm. My device is back to life and working good
But some apps (play store, maps, etc) are shown as broken as I had earlier moved them to a second partition on my SD card.
I tried downloading play store apk, maps apk and tried to install, but installation is a failure
Is there any way to restore these apps?

Serial number
Hi there, I'm a complete novice at this but giving it a go...I'm up to step three and have opened the original firmware folder and run the application, but whenever I type the serial number (or the IMEI number - have tried both) and hit "save" it says "Unsuccessful in connecting to server or phone information is wrong!"
Any tips to get through this step?

I also have a problem like this, and at the same bootloop "fastboot mode started udc_start ()". So I followed the tutorial as you post. It's just that there is a problem at the last moment, that is the error message by KDZ (like in the picture), whereas in the log is written "FINISHED" but instead restart my phone to fastboot mode (after previously being in emergency mode) and nothing happened.
Earlier after I remove the error message, there is a new log message after the "FINISHED". Is there someone who can give me help? :angel::angel::angellease !!! Until now my LG still brick do not know how what I can do.......:crying::crying::crying::crying:
Hey all,
just posting a fix for support tools getting stuck at 49% and failing. as iv seen a lot of it but no answers

I followed the KDZ method in this guide (thanks hyelton)

i got the correct KDZ for my phone from here: http://lg-phone-firmware.com/index.php?id_mod=36
Not sure if it has to be done but others said it helped but that is to Disable OR uninstall the LGE Modem from Device manager and set your phone to Port41
1: Put your phone in download mode by holding the Vol + and pluging in
2: Now in the select type Drop down box choose "CDMA"
3: set phone mode to "EMERGANCY_CS"
4: Select your KDZ file
5: Select "CSE Web Upgrade Test"

I bricked my phone trying to flash cloudyG2 3.3 and I've been trying for more than 16 hours to unbrick using stock rom. I can tell you I'm not new to flashing yet I've searched all over the net and none of the proposed solutions worked.
However, after almost giving up on my beautiful monster, LG G2, I came across your post. I tried it and got instant results! The entire operation took me less than 5mins and
my phone was back online!
Thank you for highlighting the switch from Diag to emergency_cs.
I don't know how else to thank you.
THANK YOU!!!!!:good::good::good:
Hello. I've tried using multiple ROMs in my rooted phone with KDZ Updater, and I guess that one of the updates hanged, or maybe it was something else... I really don't know. What I do know is that my phone currently isn't able to enter recovery mode, and is also not showing any boot logos (neither 'LG' nor 'Android').
I did see some threads about this, one of them talking about starting in Download Mode and using KDZ in CS_Emergency mode with some French ROM. Well, I tried that and as soon as I press "Launch software upgrade" the program freezes until I plug my phone off the PC.
I feel as if something was stuck in my throat and the only way to get it out is by completing this... so any help will be greatly appreciated!
PS: All this happened in the process of trying to install Cyanogen Mod 10.1 (which I did not try yet).

Thanks for the reply!
I appreciate the info, and I'll be checking what you've said. All the links in that thread are inaccessible because Fileserve only lets you download what you upload. Anyway, I'm curious as to what this "DLL" file does on a smartphone... why do I need these things? I never heard of them being mentioned anywhere.
I'll start educating myself ASAP. Meanwhile, thank you very much (and by the way, if it's of help to anyone, my phone is a GT540g from Personal, Argentina.
You're welcome. Sorry, didn't check to see if the files were still there and most every other site just had reposts of the fileserve links. However, finally found what you need here:
http://files-gsm.ru/lg flesh/GT540gAT-00-V20a-722-34-DEC-28-2010+0.dz.zip
I found this dll for your phone but not sure if it works with the firmware you have for that version:
http://www.mediafire.com/download/9v9e78xronadm0c/GT540g_100506_MP.dll
"A dynamic-link library (DLL) file is an executable file that allows programs to share code and other resources necessary to perform particular tasks..."
Basically it ties together a few things in Windows to let the flash tool work for your specific device is my understanding. But they have to be specific to the phone or it won't run once it checks the build.prop of the phone vs the firmware you're trying to install.
Keep in mind, I do not have this phone and have no way to test if they will or won't work so just like any other mod or upgrade - you do so at your own risk.
Thanks, but...
First of all, I'm very sorry not to have replied before, but I've been busy. Anyway!
Thanks, I appreciate the links, but I don't understand where to put the .dll file in my phone. I know you'd think I'm an idiot who doesn't know how to use Google, but I actually did search beforehand. I simply don't get where to put it.
Also, if it's worth the shot, I just noticed that I should disable the "Modem" that activates when I plug my phone in. The problem is, KDZ just does this simple log [attached] and states "===FINISHED===" (Note that I have 2 Modems listed in my device manager [attached screenshot])
Solution GT540
Thanks for your help everyone, I came to a solution after a full year lol. Here's my enlightenment, from another Thread:
Just wanted to leave my 2 cents here, I've been trying to do my best since around august 2014, no success. 2 days ago I retried this, and I DID IT! I will tell everyone what I did very shortly:
My problem that I solved: I can boot, device works like a charm. But: no boot logos, no recovery.
My solution for TL;DR: UNINSTALL ALL DRIVERS FROM DEVICE MANAGER 1ST, then reinstall. After that, flash a fastboot ROM and use it to WIPE ALL THE DATA IN YOUR PHONE! THIS was what I needed and was never explained: you had to WIPE the old data in order to get the boot screens back.
IN THIS ORDER (THANK YOU to those people from previous replies, gathering all your info was of great value):
Uninstall all of your phone drivers from your PC!!! This is what made most of my headaches go away, just use Device Manager and uninstall anything from LGE. After that, plug in your device in your USB ports (always BACK ports, not front ports, important). It should detect all drivers and download them.
IF it fails (it generally does with LGE USB Modem), you can go to Device Manager > Unknown Device (the one that wasn't recognized) > Right Click and Update > Choose 2nd option, then choose "choose from a list of local controllers" (or whatever the button says). After that, scroll down to LG Electronics, Inc. and install what didn't install.
I also found these drivers, but I did not test them: http://www.mediafire.com/download/p693hcz6kkouh19/USB_Driver_LG_GT540.zip
Huzzah!
Now you're set to begin:
FIRST thing you wanna do is a factory reset, this is something I'd forgotten with time, don't make the same mistake as I did. You can do it by turning your phone on and pressing Volume +/- & Home & Quick Search buttons all together for 5 seconds (it works, be patient and wait for it, even if you open the camera or any other stuff).
Download this Google SDK Tools (unzip and put the folder in C:\ drive) and this Fastboot drivers for GT540 (unzip and put the files inside the folder in C:\android-sdk).
Skip this next line if you know your ROM has fastboot.
Now, if you don't have a ROM with fastboot, I recommend you use either European Open+Fastboot or V20C Orange France Fastboot ROM.
Click to expand...
Click to collapse
Since you have Fastboot enabled, now all you need to do is turn off your device (all this with its battery on it, no weird things) and hold the Camera button before turning it back on. This should take you either to a black screen, or simply to no display, like me. Either one will work anyways.
Now press the Windows key > Type cmd and open it with Right Click > Run as Administrator.
In it, type all this, command by command (you can paste by right clicking):
cd C:\android-sdk
fastboot -w
fastboot erase boot
fastboot erase system
fastboot -w
fastboot reboot
Click to expand...
Click to collapse
And now it's go time! Do what everyone else says in here: Take out your phone's battery, SD and SIM cards, fire KDZ Updater up as Administrator (If your KDZ freezes, then it's either faulty or you did not install msxml, look for a good KDZ that comes with that file and delete your current one), choose CS_Emergency PhoneMode and:
1-Plug your phone while holding the volume DOWN button (don't worry! My phone didn't show "Download Mode" either, if you hear the Windows "Somethingpluggedin" Bump noise, it's ok).
2-Flash French V20A
3-Unplug your phone once KDZ says "==FINISHED==".
4-Plug it once again, holding the volume DOWN button.
5-Flash out.kdz (remember! it's CS_Emergency).

i hard brick my phone yesterday. trying to flash bootloader with flashfire. (the lazy way) thats what i get. anyways could not turn on n6p, tried charging it for a couple of hours, try holding power button for 30 seconds, try power + volume . tried holding all buttons. nothing work.. read some threads saying its done. look for new phone or send to get repair. then i found tenfar thread. long story short. i used some of tenfar info and rwj5279955.. so big thanks to these two users
here is what i did to get my N6p to turn back on.. brick by bootloader.. this is my first how to .. bear with me. please.
you will need the following https://drive.google.com/file/d/0By19rrbnQfVUVFZEVUZqQzY1RWs/view?usp=sharing
Qualcomm drivers
QFIL software
3 files, patch0, prog_emmc_firehose, rawprogram0 .. for this to work
1. install qualcomm drivers, Connect phone to pc, open Device Manager. if you see under com port Qualcomm USB loader or something along those lines. your good, go to step 2. if not disconnect phone hold power button for 10 seconds, wait for 5 seconds connect phone to pc. check if in com ports you see Qualcomm drives. if you can not get qualcom drivers on com port. just stop. its not going to work..
2. extract the three files. in a folder somewhere easy to remember.
3. install the QFIL software, . once install run QFIL.
4. in QFIL software
if qualcomm driver are found it will say on top of QFIL software Qualcom USB loader 9008
Select Build Type: click Meta Build
Select Build :: patch0 ... if for some reason patch0 doesnt work try rawprogram0
Select Programmer:: pro_emmc_firehose
hit download ...if the blue bar get to half way mark your golden. its going to always fail. the trick is to get the blue bar at least half ways. then you disconnect phone, hold power button, it should turn on.. then you ADB what ever you need to do.
for those that get the fail right away.. while phone connected to pc, hold power button until drivers disappear from device manager.. then disconnect phone, wait for 5 seconds, hold power button, for 10 second,.. wait for 5 seconds .. then connect phone back to pc, wait for device manager to see drivers.. then hit the download button . do this part over and over again ..until it works..
sorry for this horrible guide.. it work for me.. hope it works for you..

Thank you so much! I messed up my 6P when I tried to flash a bootloader image via Flashfire. I hadn't been in a brick this bas since the good old days of Gingerbread and ROM Manager! For anyone else having similar issues, I got my dead 6P to be recognized as QHSUSB_bulk eventually in Windows 7. I then edited the rawprogram0.xml file (from OP's link) in a text editor. I removed the entries for all the other partitions I didn't want to overwrite (like system and vendor and userdata), leaving only the sbl1 (secondary bootloader, the part of the firmware that actually boots into the system/recovery/bootloader when the device is first powered on) partition entry - because that's what Flashfire said it had flashed the entire bootloader image to. Doing a bit of research, I found that our bootloader image is actually just many different small partitions all grouped together into a single image file. I couldn't figure out how to unpack the bootloader image, so I downloaded a full firmware OTA zip from Google, and lo and behold, there was a "bootloader.sbl1.img" (along with other small partitions) file in the OTA zip. I changed the sbl1.img entry in the rawprogram0.xml file so that it correlated with the filename "bootloader.sbl1.img", I moved the image file into the same folder as the rawprogram0.xml, and then I was able to restore my device to it's previous functionality using the "flat build" download configuration in QFil, though the whole process did take me like 3 hours. Lesson learned - screw using Flashfire for bootloader images.
ERROR: Could not access "C:\temp\vendor.img" with access mode 'rb'
When I'm finally lucky, rebooting, replugging the phone, it looks like it might flash...
...then I see this.
I've given all permissions to all users for full control, on the file, I've run time program as administrator, I don't know what else to do. If it can't open the file, I can't flash my phone. I'm not a Windows administrator so I don't really know what to do to get this to work and I can't find any hints on the forums.
