[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

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

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!

[GUIDE] How to UNBRICK your Optimus G - security error, bootloop etc

For whatever reasons (improper rooting/flashing, power outage during updating, freezing/removal of LG bloatwares or simple bad luck etc), if you bricked your Optimus G and is stuck with a Security Error or in a bootloop, fear not, as long as you can put it into Download and Recovery Mode, all is not lost.
I got the korean version of the (almost) Optimus G (Optimus LTE2, f160k) and ran into the same security error problem that happened out of the blue.
The steps that I undertook below resolved the problem for me and has been proven to work on Optimus G by fellow members.
http://forum.xda-developers.com/showpost.php?p=34516791&postcount=29
1) Download the latest KDZ from LG's server for your phone via the app below (kudos to the creator)
http://www.mediafire.com/?cgeb6o5osy2yl9c
2) Make sure you have LG United Drivers already installed, otherwise download from below
http://www.mediafire.com/?82nt1aeh04aqa3m
3) Download LG KDZ Updater
http://www.mediafire.com/?sj5y073xal03ntw
4) Download the manual adb wipe batch file
http://www.mediafire.com/?ru7erfxsz7p7s3p
5) Put your Optimus G into Download Mode by switching it off, attaching the usb cable to the phone, holding both the up and down volume buttons at the same time and lastly inserting the usb cable into the computer; wait for the drivers to finish loading if doing it for the first time.
6) Unzip the downloaded updater zip file and run KDZ_FW_UPD.exe. Use the settings below
Type: 3GQCT
Phone Mode: CS_Emergency
KDZ file: navigate to the folder which you have saved the downloaded KDZ from the step (1)
Click Launch Software Update and wait for the flash process to finish
7) Your phone will restart itself when IParam = 90 is displayed and proceed slower until you see IParam=1 again (which signals the end of flash, you can safely exit the program then and remove the cable from the phone). If phone boots up normally, congrats, skip the steps below and proceed to use the phone as per normal.
However, this most probably will not be the case for newer Optimus-es, as the data partition somehow wasn't wiped even when KDZ-ed, remaining 'dirty', thus causing bootloop or security infringement.
8) If the phone is stuck at the booting up LG/Telco logo, you will need to manually wipe the data partition.
9) Force the phone off by holding the power button for appx 15secs.
10) Put the phone into recovery mode by holding the volume up and home button concurrently, then press the power button. Let go of all the buttons after you see the LG logo on screen for the 2nd time and the screen goes blank thereafter (backlight may still be on). The phone will kind of reboot and then enters recovery mode. Repeat the process if you did not get it the first time.
11) With the phone in Recovery Mode, connect it to the computer, wait for the drivers to load (if doing it for the first time), unzip the wipe batch file downloaded earlier from step (4), double click on wipe.bat to execute the wipe command.
12) Your phone will auto reboot when wiped and (hopefully) boot as per normal.
Hope with this simple guide fellow members will feel safer when rooting or removing non essential LG wares from their Optimus G.

Tried this, however the phone get stuck on a bootloop. It's stuck on bootanimation. I also tried to clear data with the adb wipe files but i end up with a phone stuck on that

Bell E973
I have E973 from Bell and it's been bricked since sunday after renaming couple of system apps.
I am trying to follow the instruction above but i can't download KDZ file with LG firmware downloader bc it just would not take my SN.
Error msg is "unsuccessful in connecting to server orphone infomations is wrong!"
Could anyone upload KDZ file for Bell E973 somewhere on the net that i can download?
It would be much appreciated..

Go here, replacing <yourimei> with your actual imei (just numbers, nothing else), it'll spit out a bunch of text including an address with the kdz.

Don't include the <> characters with your imei, I just put those there to mark where the IMEI goes
Also, your IMEI should be 15 digits, and I've only used this on my computer, so I'm not sure if it works on mobile browser or not, and if that's how you're trying it.

2nd thracky's view.
would recommend u do it on the PC, use the app, enter your model E973, enter your imei (15 digits, usually means omitting the the last 0 or digit), shd be able to download your KDZ.

did u wipe in recovery mode?
can you put your phone into download mode again?
if yes, try the whole process again?
as long as your phone can still enter download mode, all is not lost, even if this method does not work,
good luck!

He couldn't get into recovery at all, that image he posted was what happened going into recovery.
I think he mangled his partition table, and I feel like KDZ wouldn't necessarily repartition everything based on my experience with tools for other phones like Odin for Samsung phones, where you explicitly have to tell it to repartition and give it a file to dictate the layout.

learned something new, thanks
KDZ-ing of LG's phones of late seem to be not as 'thorough' as previous, it used to be the be all and end all; or maybe i didnt mangle my phone bad enough
has he tried upgrading via LG's update tool instead?
he may need to KDZ an older version first (if available) so LG tool can sense an upgrade is necessary, and hopefully, it is intelligent enough to repartition if one is necessary.
also, LG's update tool has in-built recovery/repair option, not sure how that works though, worth to explore?

Yep update tool was tried, recovery wouldn't work either. He wound up exchanging the phone anyways

I could not find the KDZ file

wish to know if there are any other ways to get the kdz?

Question for Sprint

6) Unzip the downloaded updater zip file and run KDZ_FW_UPD.exe. Use the settings below

Question, on the Sprint version of this phone, would the type be CDMA?
Also, do you think anything else would be different?
*edit* Also, when I try to download the KDZ file, it is instead a .CAB file that has an .wdb, .wdh, and a .dll file inside.
Am I supposed to rename it? convert it?
Thanks!

I can not get it to download the KDZ file either. Is there anyway to post a link for a direct download?

This should not be used for the Sprint or AT&T variants, please see instructions for restoring with LGNPST in the respective forums as we have .tot files for both AT&T and Sprint.

Thank you. I have seen that but I do not know how to flash the TOT file. I have downloaded that, but do not know how to flash it.

I wouldn't work for me until I added 1 more step
First of all, thanks again to the poster and xda in general...y'all freakin rule.
I couldn't get this to work for the longest time, though I knew that these valuable instructions were the key to fixing my device.
The difference between total failure and absolute success for me was making sure to run "msxml.msi" in the KDZ updater before running "KDZ_FW_UPD.exe"
If you're stuck, try that!!!
Thanks once again for helping me fix my device!

hello, if there is no juice, you can try to do as I did to my D855, I think it is the same, you will need to open your device and make a trick to go to downlaod mode.
IT is very esay that I put my LG G3 in download mode in 3minutes.
---------- Post added at 02:19 AM ---------- Previous post was at 02:08 AM ----------
just go with this guide , it is good.
http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
I did like it said and I got my phone repaired.
But, in step 8, I suggest you to not flash all stuff, because I think It is not necessary, I am pretty sure this was my cause to have the message : "Can't find matched cust for NT-code mcc/mnc"
I hard bricked my phone a second time, but instead of doing step 8 like he says. I just Made SDRAM test also and start. it will flash necessary stuff and reboot phone automatically.
To make a summary of what you need to do:
-- first put your windows in test mode if you have windows 64bits and install drivers
1-put your phone in download mode (screen off and without battery-sort of emergency download mode)
2-run boarddiag by willcracker and extract your Bin file in a folder.
3-choose port and choose folder
4-run the AP check and EMMC test
5-Run AP check, Emmc test and SDRAM test
6-phone will reboot
7-put him in download mode and flash you tot file
Done!

first, just skip steps 8 and 9 and replace it with:
it is a little bit mixed up but this is what he wanted to say:
6- choose port and folder where you extracted TOT file.
7- Check "AP" and "EMMC" and press start
here you finished with the link.
8+9- you need to Check "AP" and "EMMC" and SDRAM , click Start.
10-flash you phone with LGUP using Refurbish and choosing the tot file. (I prefer LG UP)

Step by Step guides on rooting / un-rooting the T-mobile LG G5 (MM 6.0.1)

Hello everyone,
Here are some step by step guides for those of you who need detailed instructions for rooting and un-rooting the T-mobile LG G5.
The guides are short and to the point and are meant to be followed one after the other (STEP#1 --> STEP#2 --> STEP#3).
For the step#3 guide, you must choose one out of the three available guides below:
Guides:
Tmobile-LGG5_pre_flash_MM_6_0_1_requirements_STEP_1
Tmobile-LGG5_pre_flash_MM_6_0_1_requirements_STEP_2
Tmobile-LGG5_flash_root_with_stock_MM_6_0_1_Re-install_STEP_3 <------ If you want to re-install stock MM 6.0.1 with root
Tmobile-LGG5_flash_root_with_stock_MM_6_0_1_Upgrade_only_STEP_3 <------ If you want to root current stock MM 6.0.1
Tmobile-LGG5_flash_Stock_UnRoot_MM_6_0_1_STEP_3 <------ If you want to have stock MM 6.0.1 only (no root, use this if you want to return the phone or sell it)
They will walk you through:
Downloading and Installing the necessary drivers / tools
Unlocking your bootloader
Flashing the stock .kdz file
Flashing the rooted .TOT file
Using TWRP to gain root status
I assume the following:
You are using a Microsoft Windows operating system (Windows 7 or above)
You understand that all data on your phone will be deleted
You understand that your warranty is now gone
You understand that YOU MUST follow the guides one after the other (1 -> 2 -> 3). If you deviate from this YOU WILL NOT be successful in rooting your phone
You understand that YOU MUST follow the steps in the guides one after the other (1 -> 2 -> 3). If you deviate from this YOU WILL NOT be successful in rooting your phone
Your phone's USB PC Connection (mode your phone is in when connected to your PC) is on File Transfer mode. ADB and Fastboot commands to the device WILL NOT work if device is not on this mode
You read the Useful tips & information for the T-mobile LG G5 post
You read the Changelog + News & Additions post
***Un-root***​
If you want to "un-root" your device (go back to default stock) use the Tmobile-LGG5_flash_Stock_UnRoot_MM_6_0_1_STEP_3 guide.
(Keep in mind that this WILL DELETE all data on the phone)
***Disclaimer***​
I take no responsibility in what you do to your phone
The step-by-step guides in this thread were made with the assumption that you will strictly follow them one after the other.
(If you don't, YOU WILL brick your phone!)
If you run into an problem, verify that you have correctly completed all the steps for each guide before posting to this thread. Most problems come from guides / steps that were skipped.
If possible use a laptop that is fully charged and plugged in to an outlet instead of a regular PC (unless it has a UPS attached to it) just in case you lose power during the flashing process.
(If you use a regular PC without a UPS attached to it and you lose power during the flashing process, YOU WILL brick your phone!)
I would like to thank the following people for making all of this possible:
tungkick
wolfu11
arjuna_
Your work and dedication does not go unnoticed, thank you. I would also like to thank anyone else not mentioned here that allowed the rest of us to get root on our beloved LG G5 phones. The android community is awesome!!!

**Changelog + News & Additions**​
Changelog (for the guides only):
7.16.16 - All guides have been updated to reflect the new 10d .kdz and .tot files. All links to tools, .kdz, and .tot files have been updated as well.
News & Additions:
7.16.16 - Multiple updates
A modified H83010d rooted .tot file has been released (thanks to Tungkick & wolfu11)
Guides are safe to use again. All links in all the guides have been updated to reflect the new H83010d files
If TWRP is not showing the internal storage but only the external SD-card take a look at post 24
7.9.16 - There is a new firmware update (H83010d) for the LG G5 (T-mobile) which is not compatible with firmware (H83010a) the .TOT files used in this thread have
If you upgrade to this new firmware, you will lose root.
There is no current way to get root on the new H83010d firmware unless the modified .TOT / KDZ files are released with TWRP included
There is an anti-rollback feature in the LG G5 (t-mobile) phone that prevents you from flashing back the H83010a firmware after you upgrade to the H83010d firmware. Attempting to do this WILL BRICK your phone!
Do not attempt to use the guides which are using H8301a .tot / kdz files if you have updated to H8301d. I will be updating the guides as soon as the H83010d modified .tot / kdz files come out.
5.29.16 - LG G5 & LG V10 possible driver issue: First reported on Post#6
If you own an LG V10 and have used your PC to root it, you most likely installed drivers, tools, and or files specific for the V10. What this means is that you may have to uninstall those drivers, tools, and or files prior to installing anything to be used for rooting the G5. This does not include the ADB program which can work for both.

i just felt the need to post and say thanks for this even though i dont need it. Great effort pulling these together, they look good and are very clear. Thanks! :good:

Thank you.

Thank you for the walk through. I had a little trouble with drivers and had to uninstall all drivers and reinstall exactly as you have it written here for it to work. I have a LG V10 which probably caused some conflict.
Two questions:
1) Does this automatically encrypt the phone? After flashing both the no verity and the SU it boots in to "encrypting" with no other option. I have not had this happen with any other device. Did I mess something up?
2) The password at the beginning of TWRP is requested every time, even after flashing the no verity zip. What did I do wrong?

ETA:
Something wasn't right about the No Verity app. I redid entire process and was able to get it to work with root being successful. Left this up for others - I Believe my mistake was using an external SD to install SU first and then no verity. For some reason they were NOT showing in TWRP on the internal SD even though I KNOW they were there.

Thank you for your input skyfox99. Your solution to the issues you faced will help others avoid them. You made me think of something I did not anticipate which is what happens when you attempt to root your G5 using the same PC you used to root a V10. I am definitely adding a service announcement to the Changelog (post#3) to address this possible issue.

When I get to step 13: Verify that the LGUP Tool works... the progress frame never shows up, even after restarting my PC. Am I missing something? Please help

Your internal storage gets wiped. That's why they weren't there.

i believe i'm having the same issue, no files show up in the explorer in TWRP regardless. I've been using a usb thumb drive with a usb c adapter to flash files from twrp. i followed directions perfectly and i still see the warning encryption message and read-only message when starting twrp every time.
i have root tho and everything seems to be working fine

Anyone find a fix to this? I'm stuck in the same spot, I've gone through the entire process twice now, including resetting the phone back to 6. No matter what I try it seems TWRP won't mount my internal storage!

I guess I'm having trouble understanding exactly what your issue is. Are you saying that when you boot into TWRP and you go to the INSTALL section to flash the encryption zip and the superSU zip you don't see the files? Can you attach a few screenshots so that I can better understand what you are going through. Thank you.

No, I copied after wipe so they were there. Computer recognized them and so does file manager.

There is a TWRP bootloop set of instructions in another thread, run those commands and see if it resolves it, maybe?

I had to reflash no verity a few times, before installing SU. There seems to be a problem with TWRP.

I didn't have any of the issues you guys are reporting in this thread. TWRP sees both internal storage and SD card. And has since I originally rooted.

Will unlocking the bootloader and rooting my phone or if I install a ROM take away my sim unlock?

This is a good question and I unfortunately do not know the answer. I truly don't think your sim will be affected but I am not sure. Sorry.

It's a very weird problem and unfortunately the only thing I can think off is that TWRP might not be compatible with the SD-Card you are using.
