[Guide] Unbricking Solution for LG Nitro HD (P930)

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!

Rooting LG H735 G4 Beat

hi, tried to search everywhere but to no avail soo far.. does anyone knows if there is an existing root guide for LG G4 Beat? its sort of a diff model but there's no sub for it so i guess ill put it at here since its still under G4 family.. :/

Do you have Android 5.0 or 5.1 installed?
First of all. Before you start to try root, download the kdz file for your phone.
The kdz is needed if something went wrong (e.g. phone not booting).
You can use the LG Flash Tool to flash the kdz to a bricked phone.
Use this link with your IMEI:
Code:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI
If it works, please post the download link for the "kdz".
Or better post the output too, but delete your IMEI!
Your link will only work if you type:
csmgdl.lgmobile.com/dn/downloader.dev?fileKey=
and then add the rest of your url instead of the given link.

It's worth trying. You need to get a partition layout. Then @autoprime will give a full command to run in DL mode for dumping the system image, and flashing it once it's been injected with root. I can inject it for you once you have the system.img dump.

I wrote an guide how you can extract the GPT and calculate the dd parameters:
[How to] Determine dd Parameters For All LG G4 Models
http://forum.xda-developers.com/g4/h...lg-g4-t3184867
Do you know how to work with linux?
Please post the outputs of gdisk into a HIDE and CODE tag. Thank you.
Maybe you are a advanced user and can Inject root yourself with the autoroot.sh method (Inject_Root_G4.zip)?
Or do you need help?
I think you have Android 5.1.1 installed, so it is not possible to use Kingroot to root your device. Is that right?

Pleasure.
I think some people also knew how to do it, but no one wanted to write a guide.
AND ALWAYS CONSIDER:
You can brick your phone if you don't know what you are doing.
Backup your files before you change anything.

Ok, well done. Is 10b the same version as currently installed on your device?
Some other details would be interesting:
Do you have an unbranded device?
Where did you buy it / where do you live? (country)
Are you an advanced user? Do you know how to work with linux?
The next steps will be:
Calculate your dd parameters and backup your system partition into a img file. Read my guide:
[How to] Determine dd Parameters For All LG G4 Models
http://forum.xda-developers.com/g4/h...lg-g4-t3184867
Please post the outputs of gdisk into a HIDE and CODE tag.
Post your calculated dd parameters, so that we can verify it.
IMPORTANT: Keep the original (unchanged) system.img on your computer (zip it).
Then:
Copy the img file to a linux system and mount it. Create a testfile (test.txt) on the mounted system partition.
Copy the img file back to your phone and try to "dd" it back over your system partition.
Check if you see the testfile on your system partition.
If that worked you have successfully overwritten your system partition.
Then:
Try to inject root with the Inject_Root_G4.zip on your linux system.
Copy the new img file to your phone and "dd" it over your system partition.
Please ask if you are not 100% sure what to do.
You are responsible for what you are doing with your device.
Backup all your data (photos, videos, messages...) before going one step further.

what do u mean 10b?
not really unbranded i guess? its a mid-tier version of the LG G4.. this is the phone.. http://www.lg.com/sg/mobile-phones/lg-G4-Beat
dont think its out at the US yet
bought it at Singapore as i recontacted my phone
nope i dont know how to use linux and im %100 not sure what to do :crying:

Ok so you are not a advanced user?
10b is the version of the kdz file. Goto Settings->Phone info->software version on your phone and post your software version.
First of all: It is not possible to root your phone without linux!
You don't have to install a linux on your computer (physically) but at least in an virtual environment (virtualbox, vmware player) or as a live distribution.
What you can do without linux is try to extract the GPT.
Which OS is installed on your computer (Win 7, 8, 10)?
Download the LG_Root.zip from
http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772
It contains the Send_Command.exe
You need this tool to open a special console when your phone is in download mode.
Do you know this tool and how to enter the download mode?

no im not an advanced user..
its software version is : V10b-SEA-XX
so i guess its a 10b?
im using windows 7 right now

Yes you have 10b installed now.
The XX means that it is unbranded.
SEA means southeast asia.
Win 7 is fine. Send_Command will work.
Download the zip from the above-mentioned thread.
Then:
Power off your device
When the device is powered off, hold volume up and insert a USB cable connected to the PC
Wait for the drivers to install

We won't follow the guide. We will do it like here:
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
(You will also find the thread is linked there.)
The thread is just a good help for the Send_Command tool.
You don't have to change the COM port.
Are you in download mode? Do you see the "Firmware Update" screen?
Use the ports.bat and note the "netdiag" COM port.
Inside of LG_Root folder hold shift and right click a blank space you should see "Open command window here"

(You will also find the thread is linked there.)
The thread is just a good help for the Send_Command tool.
You don't have to change the COM port.
Are you in download mode? Do you see the "Firmware Update" screen?
User ports.bat and note the "netdiag" COM port.
Then enter:
Code:
Send_Command.exe \\.\COM#
Replace # with your number.

are you opening send command from the command prompt?

Do NOT double click on the Send_Command.exe
READ again:
Inside of LG_Root folder hold shift and right click a blank space you should see "Open command window here"

Then enter "Send_Command.exe \\.\COM#"

oh okay means im on the right path..
so now i just do this as follows?
Type "id" and press enter (no quotes).
You should get back some text starting with "uid=(0)root gid=(0)root". If not, press CTRL-C, and do step 9 again (the application sometimes doesn't respond on the first command).
Run the command specified in the section below titled 'Commands to Run' to flash the rooted system image.
After a few minutes of sitting, you should get back a "#" prompt. This indicates the process has finished.
Type "LEAVE" (no quotes) and press enter. Your phone should reboot, and your phone will be rooted.

[Help] LG G4 H815 LGUP failure

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)
14) Click on "Start" and DON'T TOUCH !!!!!!
Big thanks to the people of this reddit post and of this XDA thread

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).

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/////

How to Install Leaked Android 10 Beta OTA on Sprint LG V50

Orginal Title: Sprint LG V50 may get Android 10 beta by End of 2019 (V450PM)
I saw this article here: https://www.mylgphones.com/sprint-lg-v50-thinq-5g-android-10-update-will-release-soon.html?amp
Leaked Frimware details:
Model:LM-V450PM
Size:1508.11MB
Android Pie 9.0: LMV450PMAT-V10p-310-120-SEP-19-2019-ARB00+0
Android 10 Beta: LMV450PMAT-V18a-310-120-OCT-29-2019-ARB00+1
File name: LMV450PM-V10p-310-to-LMV450PM-V18a-310.up
Click to expand...
Click to collapse
The article source won't release the beta frimware though. Anybody know where/how to get this or convince them to share it? However though, this is great news!
Edit: Special Thanks to chortya for purchasing the file. The link to download the file comes from the domain dl01.gdms.lge.com which is a legit source from LG directly. The file received is a .mo file, you just rename it to get a .up file. chortya has graciously shared the OTA file in the mega.nz link below!

Edit 2: Wow, that was fast! Thanks to aiap for figuring out how to flash this OTA.
aiap said:
SUCCESS!
I ended up not using LGUP, instead this is how I did it. (Make sure to backup, for some reason I had to factory reset because mine was stuck rebooting after "android is installing" notification completed.)
STEPS:
1. Download .up file: https://mega.nz/#!gjJi3KiK!ebsQdxmnXtEYRiG69F5oAlVqNnsZ3c9D7SpWahGI8OQ (thanks @chortya)
2. Rename file to LGUP_FOTA.up
3. Place file in root of internal storage on V50.
4. Download "Activity Launcher" from Play Store
5. Find FOTA Update
6. Hit the first option (com.lge.lgfota.permission.FotaTestActivity)
7. Follow prompts.

No I'm just saying I would happily contribute the $7

I am not able to install it. Tried multiple options:
- LGUP FOTA upgrade - device protected error
- recovery mode - both SD card recovery and adb are not working. SD card mounting fails and it seems that my V50 is not connecting to PC if in recovery mode so adb does not see it. adb works fine with phone fully booted, so developer options are enabled and phone is authenticated with pc
- lgup_cmd does not even recognize *.up files
Any thoughts?
Does it make sense to move this to the kernel/firmware section?

Yes. You must flash it with LG-UP 1.16.0.3.
Install lg USB drivers 4.4.2
Install lgup 1.16.0.3
Install lg common dll 1.40
Download and Copy the ui config file (from the LG-UP thread here on the forum) and paste it where the common dll is.
Then enable USB debugging in dev options
Then connect to pc
Then start lg up
Then chose FOTA upgrade
Then load your android 10 beta fota file. Make sure it has. Up extension
Then click start on lgup. Wait for the minute and it should start flashing.

My setup is exactly as you described. I need to check the version if the USB driver, but don't think this will improve anything.
As I have written I am getting "protected device" error.
My V50 is locked, does it have any influence?
