Unbricking Guide:
(Guide for the American version of the device - LG Nitro HD)
*** Remember, whatever you do, you do at your own risk and responsibility for your actions rests solely on you ***
Introduction:
Sorry, I know my english is not so well as I want, but I tried to explain all steps in this guide for people who never flashed their devices before.
Please, don't mirror links to required tools and files on other sites! Daily traffic is limited!
Required tools:
1) ADB: Get it from here - Android Developer SDK , and then specify the path (PATH) to the folder containing the ADB.
Alternate method: copy the folder ADB from the folder SuperOneClickv2.3.2_ShortFuse to the drive C:/ on the computer, and then specify the path (PATH) to the folder containing the ADB.
How to specify the path to the ADB:
My computer (right mouse button) -> Properties -> Advanced System Settings -> Environment Variables -> In the lower window find the line Path and double click on it -> At the end of the string "Value" add the complete path to the ADB (eg C:/ADB) and click OK (don't forget to add ";" before).
2) SuperOneClick: Link - Mirror1 - Mirror2
3) LG P930 drivers: Link - Mirror1 - Mirror2
4) KDZ_FW_UPD_EN: Link - Mirror1 - Mirror2
5) Small HTTP Server:
a) shttp3: Link - Mirror1 - Mirror2
b) www: Link - Mirror1 - Mirror2
Required files:
1) V10F_00.kdz: Link - Mirror1 - Mirror2
2) boot.img: Link - Mirror1 - Mirror2
3) recovery.img: Link - Mirror1 - Mirror2
4) firmware.img: Link - Mirror1 - Mirror2
5) baseband.img: Link - Mirror1 - Mirror2
6) system.img: Link - Mirror1 - Mirror2
So now we have everything we need to restore our system. It remains only to extract all the files and you can get to work.
The process of resuscitation:
1) Install the drivers from folder LG P930 drivers.
2) Install the B2CAppSetup from folder KDZ_FW_UPD_EN.
3) Install shttp3.exe on drive C:/, note "I agree with this license, and I accept all items", "Update entry in main menu" and "Add to startup".
4) Run the program http.exe, click the right mouse button on the top of the Small Server and select Server -> Settings...
5) Go to the tab HTTP, in the "TCP/IP port for HTTP server" change port 80 to port 9002 and at the top right click on OK.
6) Unpack content of the www.ziр in the folder C:/shttps/www.
It is important:
Small Server software must be running, or unbricking will not be possible.
7) Open with a notepad (as Administrator) file hosts, which is located in C:/Windows/System32/drivers/etc and at the end add the following:
127.0.0.1 csmg.lgmobile.com
Save and exit.
8) Switch the phone to Download mode:
Turn off the phone, if you have not turned off.
Disconnect the USB cable from the phone if connected.
Hold down Volume Up and connect the USB cable to the phone.
Hold Volume Up until the screen: Download mode.
9) Open the folder KDZ_FW_UPD_EN and run the program UpTestEX_mod2_marwin.exe
10) Click on the folder icon in the row "Select kdz file" and select the file V10F_00.kdz
11) Click on "CSE web upgrade test".
12) In the window that appears, click on "Upgrade Start".
13) In the next window that appears, you will be prompted to select country and language, which will use the program. Since few of us know Korean, change the language to English, and follow on.
14) The program will begin to flash update file V10F_00.kdz on your phone.
It is important:
If you notice that the software update stuck at 4%, close the program through Task Manager and go to step 5!
15) When the update reaches 90% of your phone will reboot. Do not do anything until the upgrade is finished completely!
It is important:
If you notice that the upgrade program generated an error at 93%, do not panic. Just forcibly restart the phone.
If you notice that the upgrade program stucked on 90% for a long time, just forcibly close the upgrade program and move on to getting root.
16) Phone revived, you can begin to get root.
Getting root:
So, your phone is officially revived the Korean language with Korean firmware by default.
Before proceeding, make sure that your phone is connected to a PC in PC Software mode.
1) A gesture from the bottom-up on the lock screen will take you to the master wizard (where everything is in Korean). Press the left button on the bottom of the screen and two seconds later your phone will "talk" to his native English. You can continue to follow the master wizard, but honestly, it's unnecessary. We just wanted to change the language.
2) Install the drivers on the PC from folder LG P930 drivers. After that, wait until the PC to install additional drivers.
3) Go to Settings -> Applications -> Development and turn on "USB debugging".
4) Run SuperOneClick.exe and click Root.
5) Wait for the completion of the root. Check in the phone that the program Superuser appears.
* If it appears, then we can begin to flash the original AT&T's images.
* If not, repeat the procedure for obtaining root.
It is important:
Be patient, sometimes it takes about 20 times to get root.
I strongly recommend to use SuperOneClick 2.3.2 version to get root! Version 2.3.3 for some reason doesn't work with our phone.
Restoring the original Nitro HD images:
1) Connect your phone to your PC in Mass Storage mode (select the type of connections Mass storage).
2) Copy to the root of the SD-card all 5 images (boot.img, recovery.img, firmware.img, baseband.img and system.img).
3) Upon completion of copying of images put the phone back into a PC Software mode and make sure USB debugging enabled.
4) On your PC go to Start -> Run -> write cmd and click OK.
5) In the window that appears, use the following commands are strictly in the order in which they are registered (otherwise, again, get a brick and will have to start from scratch):
Code:
adb shell
su
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p8
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p13
dd if=/sdcard/firmware.img of=/dev/block/mmcblk0p1
dd if=/sdcard/baseband.img of=/dev/block/mmcblk0p14
dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
6) Wait for the completion of the last command (it takes quite a long time) and forcibly turn off the phone.
7) At the same time hold down the Power button and Volume Down and wait for the screen: Factory reset.
8) Double-click on the power button, confirming our actions.
* Phone will start factory reset and will restart at the end.
Congratulations! Now your phone has an AT&T's operator firmware and root-rights.
Guys, I'm really happy to be a part of this great community, but I decided to move on. Thanks to all of you!
HI,
hey, quick question sort of on/off-topic ;-)
does it matter which kdz i initially flash? in other words, after all the new images are moved over, the initial kdz is irrelevant right? Reason I ask is I did this using the v10i kdz

No, it doesn't matter. You can flash any kdz you want, but I prefer the v10f.
why's the preference for v10f?
I can go back and reflash my device with the v10f if it's better, easy breezy.

It's only because of getting root. I have tried to get root with v10i.kdz many times and I have never succeeded. With v10f.kdz I have not any problems to get root. Yes, sometimes it takes about 10-20 attempts to get root, but in the end is always obtained.
My phone is stuck at the pink LG Optimus LTE screen, there is a progress bar below which moves for few seconds initially but then freezes.
The update tool completes the flashing to 100% and says update completed but the phone doesn't boot.
Any help??
fyi, I was on CM9 nightly before this and wanted to go back stock.

Sorry, I don't know what is the steps you need to do before you want to go back to stock from CM9. I guess you need to flash the original boot.img before, but I'm not sure.
But is there any way to go past this LG Optimus LTE screen or install recovery from outside or flashing img partitions from this state?
Plz help... it seems my phone is gone

Did you try doing a factory reset?
yes did.. no use, still the same.

There's one more thing..
The marwin tool from the KDZ_FW_UPD_EN.zip file i downloaded using the above link does not have any option to "CSE web upgrade test", the option it gives me is only "Normal web upgrade test". Till now i have been using only that and does it does complete the flashing process, although leads to the pink horror.
Uploading LGP930AT-01-V10j-310-410-FEB-26-2012.zip Please Wait...
Ill update this post when it finish's. This is the latest version they have for it. You can just recover using LGNPST. Ill grab dll later to. Just place in E-mode. Select DLL select TOT and restore.
@amoamare,
Is this just the small 20mb update or is it the full recovery image?
Hello, sorry to derail your thread for a minute, but just dropping by to let you know that this thread has been featured on the XDA Portal
Link
http://www.xda-developers.com/android/unbrick-your-lg-nitro-hd-with-this-guide/
I hope you enjoy it!
@Malnilion,
Its a full 300 MEG File in .TOT format needs to be flashed using LGNPST. It is not the standard system, recovery, boot.img formats.
You must use LGNPST to flash the device, but you can flash in recovery mode to unbrick a device.

File is 300Megs
@amoamare,
This is truly awesome! This should completely eliminate the need for people to flash the SU-640 rom if they brick their Nitro.
Now you still need the dll for this phone and LGNPST.
Also fair warning. I don't know if GSM phones when flashed in recovery or not loose there IMEI like the cdma versions. Im not responsible for any damages.
I will upload the dll when I get back.
Thank you thank you thank you
I registered on this site just to say thank you for this. I actually never bricked my phone ... just installed the ota update to v10j, which made it impossible to root it. So I followed this guide (I know it was probably a little risky) and finally rooted my phone after a week of failed attempts.
Thanks.

This looks like a ray of life for my phone which is dead since past 2 days... Thanks a ton!!
Can someone plz comment or elaborate more on this tool and how to use it? Also, how about the IMEI issue @amoamare mentioned?
Did any1 try this?
This will be excellent if it is ATT stock V10f.
Question: do we need to select type? ex: CDMA or CMDA-Smart Phone (WM) or doesnt matter?
(For ATT Nitro HD)
Thanks everyone!

Hi,
Just spent a day figuring out the issue.
1. The software is now checking online and require internet, when you connect to internet it downloads the files from internet and you can not use the KDZ file
2. In order to use the KDZ file you have to find a older version
Check this URL,
http://forum.shiftdelete.net/lg/364123-lg-g2-kzd-yukleme-lg_kdz_fw-update_offlinefix.html
It has a download link to this file [http://dosya.co/xixcjv2lkth6/LG_KDZ_FW-Update_OfflineFix.rar.html]
1. change 'hosts' file in C:\Windows\System32\drivers\etc and add - 127.0.0.1 csmg.lgmobile.com
2. Install some webserver, i am a webdeveloper so I already had APACHE web server installed.
3. By default, apache listens to port 80, change it to 9002 as the update software try connecting to lgmobile.com on this port
4. When done, follow the tutorial on the Turkish forum... here is something which i understood from there
1 - lg_kdz_fw-update_offlinefix \ b2cappsetup Extract these folders somewhere. There are two folders, "LGMOBILEAX FIX", "LG_KDZ_FW-Update_OfflineFix"
2 - c: \ ProgramData \ lgmobileax delete the contents. (If you can not find the folder create an empty folder)
3 - "lgmobileax fix" paste the files in the c: \ ProgramData \ lgmobileax folder
4 - C: \ Windows \ System32 \ drivers \ etc folder, scroll to and open the hosts file with notepad and at the bottom in "127.0.0.1 csmg.lgmobile.co I type" (without quotes)
5 - automatic offline file, run the procedure and confirm the warning GROUPS - i dont know what does that mean, so ignore it :laugh:
6 - There is a VBS file, well you can run from there or manually follow the tutorial to run the windows enabler and other file using win xp mode and stuff, you know what you are doig... right?
7 - Turn your phone settings developer settings and USB debugging mode on, if your phone is in DOWNLOAD MODE then no worries
8 - unmute your phone by pressing and holding the usb cable. will go into download mode.
9 - R & D test tool 3gqct in the program and bring the selected diag.
10 - at the bottom right of the screen windows enabler program has opened. Click it once and turn it over ten written.
11 - kdz select your file and click on the normal web upgrade test.
12 - The Republic of Korea has been selected under the on-screen language is not set in quarters. Click OK to start processing of fear.
13 - the phone will be opened automatically after installation.
(If your phone restarts itself constantly by long-pressing the power button, power off. Then take a hard format. Then did not pick up the phone I have installed has been installed smoothly kdz file)
so i hope this will work for you,,,
if it does.. press thanks
thanks
Thanks dear for looking into the problem. Will try it and update you later

Hello!
I tried to update my Vodafone Branded G4 with the europe not branded version H81520g_00_0720.kdz
The problem ist i just get "error code = 0x2000, invalid command response" from the LGUP software and everytime i start the phone it is in firmware update mode.
Any idea how to fix this?
Greetings
I got this too as I tried to install H81520o_00_0310.kdz then I thought that it is maybe related to the brand. So I download your kdz file and then it was working.
So I would guess try another number is the best what you can do. I believe it is because of selection of "upgrade". If you have a tot file for refurbish, then maybe another is working, but I didn't do this yet.
Probably the problem is the DLL.
Extract the DLL from the KDZ (the one you want to flash) and replace it with the one you have in LGUP (path; C:/Program files/LG Electronics/LGUP/Model/8992).

Hi,
I have LG H811 (T-Mobile) Variant. I receive error from LGUP everytime I try to flash this ROM=h81120x_00_1108.kdz
My LGUP shows COM =COM3 and Version=H81120v
The error is thrown at 9%
Nothing working for me I am very frustrated!!!
PLEASE SOMEBODY HELP ME!
Stuck with LG G4 (H81520i)
Same for me but with LG H81520i. I tried to flash these ROM* with their specific .dll that I extracted thanks to WindowsLGFirmwareExtract-1.2.5.0-Release. Always get "error code = 0x2000, invalid command response" from LGUP. The error is thrown at 16% on the computer, but at 7% on the phone. Now, I'm stuck in download mode. I also tried to change the COM port number, doesn't change anything.
*Europe General H81510B_00.kdz ; Europe OPEN H81510D.kdz ; H81510D_00.kdz ; H81520i_00_0922.kdz ; SEA H81510B.kdz
Only one ROM above matches the LG H81520i (the fourth one).
Informations about my (ex-)android firmware :
- Android version : 6.0 (Marshmallow)
- Kernel version : 3.10.84
- Software version : V20-SEA-XX
PS : H81520i is what is written on the LGUP software
______________________________________________________________________________
I found a solution (after several hours)
Uninstall all your LG softwares (except LG Bridge or others LG backup softwares) and go to 'C:\Program Files (x86)\LG Electronics\' to delete all folders and files.
Go to this link and click on "Download all". Extract the file and follow the instructions :
1) Install "LGMobileSupportTool.exe"
2) Install "LGMobileDriver_WHQL_Ver_4.2.0.exe"
3) Install "LGUP_Install_Ver_1_14_3.msi"
4) Install "LGUP_8994_DLL_Ver_0_0_3_23.msi"
5) Move "LGUP_8994.dll" in the repertory 'C:\Program Files (x86)\LG Electronics\LGUP\model\8994'
6) Open "LGMobile Support Tool" and click on "Install USB driver." to the left
7) Select "LGH815" (or your model) et follow the drivers installation steps
8) Do step 5) again
9) Shut off your LG and plug it to your computer while pressing volume up in order to enter download mode
10) Unplug your LG and the battery
11) Open "LGUP" and close it
12) Do step 9 again (download mode)
13) Open "LGUP", select "UPGRADE" and go select your .kdz file (the ones in the file that you downloaded or another one you have)

Thanks Lucas for your time and help. It didn't work for me. I flashed another ROM named H811V20r_00_0111.kdz and it worked like a charm and it's tested on so many devices afterwards which worked fine without a single issue.
Here is the link to the ROM: https://lg-roms.com/official-firmware/LG G4-LGH811VK/H811V20r_00_0111/
Thanks for the help though.

You need H81520p.kdz to downgrade from Nougat!
You can download from here: https://www.4shared.com/file/hfyqh6iEfi/H81520p_00_0314.html
Can also see here if you need more files: https://forum.xda-developers.com/showpost.php?p=76571471&postcount=23
Okay I'll try this but please tell me that
I have to copy lgup_8994.dll from H81520p or use original dll which is installed with the LGUP 8994 installer???

After install everything, replace the one in "C:\Program Files (x86)\LG Electronics\LGUP\model\8994" by the given one (or extract from the H81520p.kdz file).
See on the picture how your phone should be detected in "Device Manager":

You first start your phone with any sim or sd card?
Try to flash it again with the v20p and restart it without any card on it.
If it doesn't solve the problem, try a v10a. Maybe it works and you can upgrade starting from there.
Good luck!
now again I tried H815v29A so it installed after the installation of old original version , now please tell the method of rooting Nougat on H815v29A urgently XDA experts???
also Twrp not installing on H815v29A which was working on marshmallow/////
experts reply???
Hi,
Goal is to upgrade my M2, I believe it has a modem because it is able to receive SMS, 4G network, etc...
One thing is missing, calling functionality, dialer stuff ... is this hardware or firmware (or driver not installed)?
Can somebody please confirm or know how these things work?
So I want to upgrade because, I just want to be up to date, new android!
No updates are available if I try the official via EMUI Update way... online at Huawei nothing is available either (they refer to EMUI). It says most current version.
But then I read people from other European countries do have updates installed, 'same' model ... WTF?!?
Version / model : M2-A01L / 2GB
* Everything is still factory.
* EMUI : 3.1
* Android : 5.1.1
* Custom version : CUSTC100D002
* Bootloader version : V100R001C00B000_FASTBOOT
* Kernel version : M2-A01LV100R001C100B006_BOOT
* AP : M2-A01LV100R001C100B006_SYSTEM
* CP Version / baseband : 21.600.20.00.010(balong)
* Cust Version : Cversion:C100 DVersion002
So first things first reading different posts and tutorials about updating:
* https://forum.xda-developers.com/mediapad-m2/how-to/guide-official-updates-m2-tablet-root-t3589363
* https://forum.xda-developers.com/me...om-official-manual-updates-m2-tablet-t3595211
Im already stuck at the official steps:
1 - On tablet created folder : InternalStorage/HwOUC placed M2-A01LV100R001C100B007.zip and rename in update.zip
2 - Turn off , Reboot device (not connected to laptop) , should automatically install update above. Nothing happens.
So lets try bootloader maybe I can choose to update from folder or something. Nope, just 3 options, (reboot:wipe cache:factory)
Strange... Im wondering
1 - If they disabled something so updating is not possible at all?
2 - Other possibility in the forum, update.app in dload... people mention the process got stuck on 2%. Can you get back to original, it just fails or do you need to do a factory reset to get a working tablet again?
3 - What steps to take to make sure you can always... yes, always get back to your factory firmware when updating.
4 - Then I was reading about simply download to a full firmware (not an update)
HUAWEI_MediaPad+M2+10.0_M2-A01L_Firmware_Android+5.1.1_EMUI+3.1_V100R001C100B010CUSTC100D001_Germany_Spain_Belgium.zip
Not Netherlands... Im not 100% confident this is the way to go. Last part of the filename D001_German... mine is D002, so, aaargh
I hope you can guide me and help me updating. I dont know much about this, is it really chipset, hardware or just software (compilation) stuff...

Making progress ... step:
0 - Back to factory settings, yes wipe that thing and let's see... then:
1 -
a - Unpacked M2-A01LV100R001C100B007.zip placed in internal storage/dload. Settings > Update > menu > local update. Package found, rebooting, installing, SUCCESS, rebooting again.
b - Open Settings > About Tablet > look at buildnr... A01LV100R001C100B006 didn't change, huh. repeated steps above...
Lets's see what happens if go to OTA-M2-A01LV100R001C100B010.zip, same steps... and after updating process. nothing changed, still the same ... A01LV100R001C100B006 ...
So somehow the manual local update looks into dload folder > changes the boot procedure to update > then looks into a factory prepped setting > updates to its original and no version change.
Edit:
Placed file 007 in internal storage > dload , powered off , then I did :
Vol + UP and Vol - Down and PowerOn buttons, waited until I got the installing EMUI screen.
Nope, nothing changed.
YESSSSS , SUCCESS :good: read!!! (and above)
- Tablet (bought in the Netherlands) - Huawei M2 10" - A01L :
* Custom version : CUSTC100D002
* Bootloader version : V100R001C00B000_FASTBOOT
* Kernel version : M2-A01LV100R001C100B006_BOOT
* AP : M2-A01LV100R001C100B006_SYSTEM
This is what I did :
- Factory reset, tried to update B006 -> B007 -> B010, nothing seemed to be changed although it said success ...
- Not rooted, no TWRP, not Developer or Manufacturer mode... just basic.
Then downloaded rom in this topic :
https://forum.xda-developers.com/mediapad-m2/development/rom-m2-a01l-lte-premium-stock-t3624094
Huawei 10 - M2 A01L - B010 LTE file
- sdcard in tablet (not internal storage)
- create folder dload
- unzip file (above) and place the contents of the extracted file and its subfolder dload into this.
- the folder contained file UPDATE.APP and hw folder. Total size 3.3GB.
- Power down
- Unplug all cables
- Check if you have sufficient power >50%
- VolUp + and VolDown - and PowerOn, wait until EMUI Install screen, takes around 15-20seconds.
- Install starts until finished, 15minutes. Slow progress.
- Looks like it hangs on 99% but wait for success
Et voila, from B006 -> B010 and yes, including dialer... made a phonecall...
Next is rooting...
As I was saying... ROOTING, success again.. what ... a .... day !!!

I read your post with interest. I was trying to do exactly the same thing i.e. enable the calling features on my M2-801L.
Eventually got my tablet fully working and your post helped a lot!!
So thanks for posting the info.
