[LG Nitro HD] wutname:
you have to install the software tools from lgs website, then use that to update. (be sure you uninstall all the crap from this guide first, then reinstall the official drivers, restarting your pc between uninstalling/installing is a good idea)

same thing happend to me.

now that i've made it past that and got the korean software, what do yaknow this S*** STILL isn't rooted.

edit: i've gone through every step, a third time now..

and after doing factory reset the phone just hangs at LG.. CWM isn't loading... >: ( this is so frustrating

edit:2 i got tired of waiting and reset my phone, tried going into cwm AND IT FINALY WORKS!!
[LG Nitro HD] Shagerty:
So I'm back on the Korean GB 2.3.6 no root and no cwm. What's the next step. Tried tpsparky and one click still no root.
[LG Nitro HD] NFleck:
Use SuperOneClickv2.3.2-ShortFuse to root GB.. then install CWM from the play store and install your rom:

Start from "Getting Root"
[LG Nitro HD] Shagerty:
Great thanks for the link. I have used super one click with no luck. Is superoneclick short fuse specific to use with the nitro hd?
[LG Nitro HD] Swetnes:
Just out of curiosity why did you skip the root step and go straight to the Korean ROM? You are just going to create a lot more work for your self and more than likely have to start the process over.
[LG Nitro HD] Shagerty:
Because I followed this.
[LG Nitro HD] NFleck:
Make sure your antivirus isnt deleting the files out of the "exploits" folder.. They're seen as dangerous by most anti-virus apps, and removed by default.. It wont root if they aren't in the folder. Disable your antivirus before unzipping, and until you have obtained root. I get root first time, every time.. And I've rooted each and every version since GB
[LG Nitro HD] Dr Doppio:
I have made multiple attempts to download the package containing LG p936 v18f KDZ, and it always fails at 19% and restarts the download. I have extracted the KeepRoot and KDZ_tools folders successfully from the partial rar archive, but the ROM itself is corrupt. I haven't been able to find this ROM elsewhere, neither as an auto-installable executable nor as a normal KDZ.

Any suggestions where I can get this ROM?

EDIT: Found the LG p936 v18f KDZ installer, from Russia with love.
[LG Nitro HD] juone95:
Can you guys please help me with this problem? I really want to root my phone!
[LG Nitro HD] Swetnes:
We need to know what stock OS you have and what you want to do.
[LG Nitro HD] Axtmus:
Hello,

I try your guide to point 14 but the KDZ_FW_UPD.exe crash any time when I try to flash the device. I use the .exe from your .rar file and fill in the information extactly like your .jpg. I try to start it in admin mode, compatiblity mode and use the "launch software update" button or the "read phone information -> upgrade start" Button. Twice ends up in a app-crash.

I use Win8 x64 and try different usb ports.

Please help me Thanks.

[LG Nitro HD] Swetnes:
I have an easy solution for win 7/8 look for my post dated March 11 on this thread.
[LG Nitro HD] Axtmus:
Thank you Swetnes, with your solution I done it. CWM is now on my phone. So which Firmware works fine on the P930?
[LG Nitro HD] Swetnes:
Just try and find one to your liking but here are a couple of recommendations:

Stock based (ICS) V20F MOD V2, LIQUID NITRO V6 + WIND KERNAL

Jellybean 4.2: JELLYBAM V7.4 + WIND KERNAL
[LG Nitro HD] Axtmus:
Damn I don't know if this is the right thread for my problem but after I installed JellyBam Versions 7.1-7.4, I get a reset every time I want to choose the language and click "start" in the first screen after boot. I do a wipe after install the rom.
[LG Nitro HD] juone95:
I have the LG P935 V20e software version. Android is on Ice Cream Sandwich. I want to root my phone! Also, the problem is that when I try to use the TPSparkyRoot tool, the command line says something about adb and it doesn't work. How should I fix it?
[LG Nitro HD] Swetnes:
There was a step you missed or something didn't get installed. Go to LG's website and make sure you have all the software installed then reinstall all the software in the Op in post #1 then REBOOT.

I am assuming you want root & cwm?
[LG Nitro HD] trojan ledge:
Is the LGMobile Support tool (or B2CAppSetup) supposed to connect to the internet? Cos it just stucks at a particular point.
[LG Nitro HD] lordcheeto03:
I don't believe so. What portion of the guide are you getting stuck?
[LG Nitro HD] trojan ledge:
Step 11 : - In the KDZ tools folder, install

msxml and run B2CAppSetup (Close the

application after it has installed)

I have msxml installed, so I double clicked on B2CAppSetup. The progress bar was on a particular position for around 30 mins. Or how long is it supposed to complete its installation?
[LG Nitro HD] lordcheeto03:
It definitely shouldn't take that long... Now that you mention that, I tried running it myself and it's not loading for me either... makes well less than 1/4 progress and just hangs up.
[LG Nitro HD] trojan ledge:
Can I progress with the flashing by skipping that part without having a faulty phone or is it that necessary?
[LG Nitro HD] lordcheeto03:
You can try it, I'm not exactly 100% sure what that app does to be honest. I don't want to give out incorrect information, but I almost swear it's the device drivers; but that wouldn't make sense.
[LG Nitro HD] trojan ledge:
I'll give it a try. I just hope it won't brick the phone. I would have liked if those successful with the whole process can reply with their own experience about the B2CAppSetup
[LG Nitro HD] lordcheeto03:
I have used the process; never actually had a problem with it. :\ It won't brick your phone if it fails. Sorry I couldn't be of greater assistance.
[LG Nitro HD] trojan ledge:
Thanx. I'll give it a try and let u know what's up

I own the P936 model. I followed the guide and successfully rooted and installed Cyanogenmod 10.1 (4.2.2).

Now my phone ID changed and it says the model is P930. In case I decide to take it back to the stock form (ID P936 and ICS 4.0.4) how am I going to do it?
[LG Nitro HD] trojan ledge:
Step 14 - Run KDZ_FW_UPD.exe. You need to

set Type to 3GQCT, PhoneMode to

CS_EMERGENCY, and point the KDZ file

field to V10F_00.kdz

(SOME PEOPLE HAVE REPORTED

HAVING TO PRESS "Read Phone Info"

FOR THIS STEP TO WORK!)

Once these settings are enabled, hit the

"Launch Software Update" button.

After performing this step, this is the error I get. I'm on Windows 7 professional-32 bit. Pls any help on this?
[LG Nitro HD] lordcheeto03:
If you decide to return back to stock, just perform the first part of the unbrick guide (reverting to v18f) and then use the official LG update tool to revert back to stock ICS with p936 ID.

I would believe that is due to not having b2capp running. Guess we answered that question.

Try to remove anything the b2capp might have installed and try reinstalling after rebooting your computer. Once my upload finishes, I'll boot into Windows and play around with mine as well; seeing as how I encountered that same problem with b2capp you described. Good luck.
[LG Nitro HD] kingdragon1:
Thanks lordcheeto03
[LG Nitro HD] Swetnes:
There is already a solution out there but to help this is a post I made on March 11th:
[LG Nitro HD] lorax1284:
what I hope is constructive criticism to enhance clarity of this guide.

...and update the phone's firmware. It's not that you are just running the app to allow for some kind of communication between the computer and the device. Click "Exit" on the updater when the process is complete.

You will have to unplug the USB cable from the device before you can turn on USB debugging... the option is disabled by default, and user interface component itself is disabled preventing you from touching it to activate (enable) the feature.... then plug in the USB cable and...

....then unplug the USB cable and...

...after the phone has booted into the AT&T firmware, swipe down from the top of the screen and go into settings and...

... then plug the USB cable back in and...

If you are repeating this process (as I am) you needn't repeat installation of MSXML (if you're running this on the same computer)

The B2CAppSetup lets you install some kind of drivers, but since an earlier instruction was to install drivers, I assume I should NOT perform the "install drivers" option. This app performs a firmware update... I'm not sure if the firmware needs to be updated or not... saying "run the app" is not the same as saying "run the app to upgrade the firmware", but for some people that's just semantics, for newbs, leaving out can be confusing... so I'm updating the firmware again.

Timing matters; if the device isn't in the correct state, the "AfterRoot" process may throw a lot of errors which I guess is a failure, so run it again until it doesn't throw errors.

Then, unplug the USB cable from the device and...

if your Korean is a little rusty, on the first screen you see, click the LEFT button of the two near the bottom of the screen, and a list of language options will appear.
[LG Nitro HD] trojan ledge:
Still getting the same error & subsequent crashing through that method also.

---------- Post added at 05:30 AM ---------- Previous post was at 05:17 AM ----------

Getting fed up with the whole process. Or could it be that my System OS (windows 7 pro 32-bit) is contributing to this? May be another system will do. Now I've performed the 1st step, installing P930_UDT_v18f_04112012 which seems to have changed the build number and I ended up having a slow responding phone.
[LG Nitro HD] trojan ledge:
This is what pop-up after trying Swetnes' method carefully. I couldn't find the tools tab it's talking about
[LG Nitro HD] trojan ledge:
No help yet? :( Guess I'll have to check other methods.
[LG Nitro HD] Swetnes:
You didn't install all the drivers. If you did uninstall REBOOT reinstall and REBOOT. You should be good to go. Also make sure the LG upgrade tool is running.
[LG Nitro HD] trojan ledge:
I unistalled & re-installed the drivers. Now I get a "Check internet line" error. I think there'll be progress if I can get past this error this time around.
[LG Nitro HD] Swetnes:
LG upgrade tool has to be running.
[LG Nitro HD] trojan ledge:
You mean the B2CAppSetup.exe? If that, it is running.
[LG Nitro HD] Swetnes:
And you are running the kdz tools from here

http://xdaforums.com/showthread.php?t=2149211?

Using those directions for setup and execution of the kdz installer?
[LG Nitro HD] trojan ledge:
I used the tools on the above link. I got same error. I also used the tool on the first page of this tool also. Same error. I hope it's not a problem with the small server (shttps) I have once set up. Though, I have since uninstalled & deleted it.

---------- Post added at 06:59 PM ---------- Previous post was at 06:30 PM ----------

Sorry if my problem is too much, but this is my 1st android & kinda new to this rooting & flashing stuff.
[LG Nitro HD] Swetnes:
OK the first guide was this the one that you needed to modify the Windows HOSTS file? If it is you either need to undo the HOSTS file OR reinstall the SHTTPS program and have that running. But I believe that if you just change your HOSTS file back and reboot you should be fine.
[LG Nitro HD] trojan ledge:
Yea, it's d guide where u needed to modify the hosts file. I've since removed the "127.0.0.1 csmg.lgmobile.com" from the hosts file and uninstalled shttps. Also restarted but I still get that "check internet line" error.
[LG Nitro HD] trojan ledge:
This is the screenshot of the error i am getting. What can i do next?
[LG Nitro HD] Swetnes:
That's the problem wrong program look for UpTestEX.exe Go to the previous link to see the image of what it looks like.
[LG Nitro HD] trojan ledge:
Yea, I do know. Even if I use the UpTestEX.exe I still get the same error.
[LG Nitro HD] trojan ledge:
Using the UpTest.exe, i still get the same error. The other attachment shows the B2CAppSetup.exe running. Doesnt go past the level it is in the screenshot.
[LG Nitro HD] trojan ledge:
How I went about it

I installed the LG United Mobile driver first, then msxsl.exe, i double-clicked on the B2CAppSetup.exe in this archive, it pops a window with "To check for software upgrades, you need to connect your PC to the internet and press continue" then 2 buttons "Continue" & "Cancel".

I had to use the B2CAppSetup.exe in Hererics' method http://xdaforums.com/showthread.php?t=2044645 http://xdaforums.com/showthread.php?t=2044645. Thatis the one that doesn't progress in the attachment above.

I opened both Windows Enabler & UpTest.exe in Windows XP SP3 compatibility mode, selected type as 3GQCT, Phone mode as CS_EMERGENCY and used the V10F_00.kdz in Hererics' post.

I clicked next on the Normal Web Upgrade Test button which brings up a "read phone information" window from which i clicked the "Upgrade start" button. Which leads to the errors described in my previous post,

Is there anything i"m doing wrong? :( PLS HELP
[LG Nitro HD] Swetnes:
I am still thinking it has something to do with the HOSTS file. Try this as an experiment: Reinstall the HTTPS app from here: http://xdaforums.com/showthread.php?t=1597488. Then set according to the directions. Have it running and repeat the KDZ installer. If it works you know your HOSTS file still is on error. But the good news it works and I wouldn't do anything more. Just remember to have the HTTPS running if you ever want to unbrick again.
[LG Nitro HD] trojan ledge:
i guess i have to click on "Normal web upgrade test" button first, then "Upgrade Start" and not "Start Upgrade" button in the UpTest.exe interface
[LG Nitro HD] Swetnes:
Correct did you get it to work?
[LG Nitro HD] trojan ledge:
Nah :( Still the "Check your internet line..." error
[LG Nitro HD] Swetnes:
OK I know there is something we are missing. Does anyone else have any ideas?

The update interface is stuck at 4% but the log seemed to have completed to 100 and the phone is bootlooping on the 2nd LG splash screen. Urgent help pls.
[LG Nitro HD] Swetnes:
Run the after.bat file then factory reset. (That's what it should be doing) so what was did you do differently this time?
[LG Nitro HD] trojan ledge:
I uninstalled shttps & redownloaded it. Reinstalled then re-configured shttps. Was up all night, so it probably took pity on me.

Thanx so much, Swetnes, 4 ur help. I really appreciate it Bro.

1 more question tho, do I need to dd if all the image files in the other thread? I didn't run 'after.bat' during the bootlooping, so I forced restart of the phone & I tried different methods to root, but was not successful. I hope to retry this morning tho.
[LG Nitro HD] Swetnes:
OK you need to root from ICS that should have been done before so follow these steps:

1. Install v18f from exe file

2. Root in TPSPARKY method

3. Wipe phone (cannot forget this)

4. Run keeproot.bat file

5. KDZ flash the v10 file

6. Run after.bat file when phone boot loops.

7. Wipe phone

8. Push CWM using dd command.

9. Enjoy :D
[LG Nitro HD] trojan ledge:
Thanx thanx thanx to Swetnes, seems like the only 1 who cared.

I was able to follow every step to the T. Now I am running CM10. Really appreciate your help. You deserve not just a bottle of beer but a full carton. thank you :thumbup:

Is this guide a proved method for acquiring root on the lg nitro HD ? I once had a lg optimus t device and that was easily rooted with gingerbreak..anyways I might be getting a lg nitro device so I'm doing a little scanning of the forums b4 I purchase the device ? Is there anything some users of the device wanna tell me ?
[LG Nitro HD] drakepayton:
Right click, "Run as administrator"
[LG Nitro HD] X0dus:
Been there; done that. Even tried it on a totally different machine with same results. I'm at a loss as to why this guide doesn't like my phone.
[LG Nitro HD] Swetnes:
You can easily root att v20c and then continue the guide from there.

http://xdaforums.com/showthread.php?t=2052321

Silly question but is your phone in either debug mode or download mode (needed).
[LG Nitro HD] drakepayton:
On step 10 noth happens when I "press any key to continue". It just closes the window. Is this normal?

Also step 15 doesn't do anything for me. Also says "press any key to continue' but then nothing happens. after I boot into the korean ROM I am not rooted so I cannot complete the process.
[LG Nitro HD] Swetnes:
If you are talking about the before.bat file yes that is normal.
[LG Nitro HD] drakepayton:
Ok cool. And what about the after (Step 15)? what should it do? It doesn't even close, just sits there.
[LG Nitro HD] Swetnes:
Close the dos window and do a factory reset on the phone.
[LG Nitro HD] drakepayton:
I have done this. That is after all the next step. (16) It boots into korean GB ROM with no root.
[LG Nitro HD] Swetnes:
OK start the process over. If you don't do a full wipe after getting root on v18f the before and after batch files won't work right.
[LG Nitro HD] drakepayton:
Thanks for the help. I'll give it a try tomorrow :fingers-crossed:
[LG Nitro HD] drakepayton:
I think I've successfully gotten past that point now (had to use a different method to root). Now when I run the KDZ_FW_UPD it wont let me click any of the options. I have run windows enabler just like last time and it says "on". I have no idea why it was working a few days ago and now it won't. Was able to click on the options just fine before

Now working on a different win7 machine go figure

Kapla! Thank's for this great guide. Thanks Swetnes for the help. For anyone having trouble with this method for att nitro you might try using this http://xdaforums.com/showthread.php?t=1886460 to root the phone instead of step 7. That was what did it for me! Hope this helps others!
[LG Nitro HD] Swetnes:
I agree step 7 is good if you don't have ICS. I made the suggestion to the OP a couple of months ago and he was supposed to have updated.
[LG Nitro HD] xZeroMancerx:
I'm confused, I've seen links to 2 or more ways of rooting the nitro HD...which method to gain root works ?
[LG Nitro HD] stickman1981:
I use this method it work find on windows 7 64 bit and this was the first rooted phone
[LG Nitro HD] xZeroMancerx:
So there's no one click method for root on this device ?
[LG Nitro HD] drakepayton:
It is not hard to root this device. The complicated part is installing a custom recovery which you need to flash any custom ROMs.
[LG Nitro HD] jaeceez:
Hi everyone, I'm new to the forums and would like to gather some insight about rooting my phone. I recently purchased the LG Optimus LTE (P935), GB 2.3.5. V10a locked to Telus and have unlocked it to work with my carrier. I was reading through the pages and would like to know if this method applies to me or should I skip it and root with one click then install Rom Manager and have it install CWM then take it from there with the custom roms?

Thanks!
[LG Nitro HD] Truepeace:
Which method should I choose?

Someone told me : "TPSparkyRoot is based on an old exploit and works on v18f(4.0.3) only." And I've read about the bin4ry method and someone told me to try it, so which method should I choose?

Please help.

About my phone:

I have an LG Nitro HD P930 bought from the USA so they wrote on it at&t and updated with the LG tool to ICS 4.0.4.

Baseband version : APQ8060/MDM9200.

Kernel version : 3.0.8-perf

Build number : IMM76D

Software version : LG-P930-V20c-JUN-25-2012
[LG Nitro HD] Swetnes:
Use this method to root v20c:

http://xdaforums.com/showthread.php?t=2052321

Just a question: are you sure you aren't already rooted? The reason is the kernal isn't stock. I have only seen 3.0.8-perf on custom versions of v20f. Something you might want to look into before spending time rooting. To check this go to the terminal app (if you don't have one free from the play store) and type su, if you are greeted with # you already have root, if you are greeted with a $ you don't.
[LG Nitro HD] yh8it:
Many thanks for this guide! After many attempts yours was the one that finally came through!!
[LG Nitro HD] assassint0r:
I used this guide, and it worked really well, I got root very easily all was well. However I've tried multiple ways to get CWM flashed, and failed. I tried the "optional" way in this guide, using ROM Manager, and manually using the terminal. Every time it seems to work but I get:

Secure booting Error!

Cause : boot certification verify

Enter the fastboot...

Enter the fastboot...

Long time no see!

The strange thing (from what I can tell) is, this only happens when trying to boot into recovery but i can still boot the phone normally. Am I missing something here?

The phone says I'm on 4.0.4, I have read these recoveries only work on gingerbread but I thought this guide would cover that? Do I need to roll back before doing this?

Thanks!
[LG Nitro HD] Swetnes:
This is the easy fix:

1. Start the guide over

2. This time complete the guide and don't skip steps 9 - 15 which will install Gingerbread.

3. Push recovery over

4. Profit
[LG Nitro HD] zijin_cheng:
On step 15, you say that it should bootloop and I should run after root, I did that but it is still bootlooping, how do I fix that?

On step 14 it kept on giving me messages such as Param not found for every single entry in the updater.

EDIT: Never mind, I thought I had to do a factory reset after the phone stopped bootlooping and booted into Android and shutting off.

Thanks for the guid,e worked first time through!
[LG Nitro HD] assassint0r:
I did complete all the steps all 3 times. Step 14 seems to be what failed (windows 7), thanks for pointing me to those steps. I used your other method to flash the KDZ and it worked. Thanks!

Nice Guide - but it really doesnt work

KDZ Update crashes at the start .

I assume, you're using Windows 8 64bit. There, it did not work for me, too. I used Windows 7 and it worked perfectly there.
[LG Nitro HD] lordnihilusmd:
Nice Guide - but it really doesnt work

No ... this is windows 7 x86 , i also tested this program on windows 7 x64 and it crashes like in win7 x86. I tried to use rom manager to install CWM on (android 4.0.4 and 4.0.3). It will mess the recovery image and system will work but it wont recover so it is recommended to flash the 4.0.3 firmware.

Ok , so is it possible to downgrade to 2.3.5 and flash a normal cwm from 4.0.3 ??
[LG Nitro HD] Swetnes:
Yes the very purpose of the guide is to downgrade to GB so cwm can be installed. There is also a win 7 work around here: http://xdaforums.com/showthread.php?t=2149211
[LG Nitro HD] lordnihilusmd:
Now it works

Thanks ... i downgraded the device succesfully to 2.3.5 and flashed cwm.

The bad new are that are that all the cyanogenmod roms are very very bad. Even the ICS or Jelly bean stable versions have major problems. For example: camera recording is so poor that the quality is like on 1 megapixel devices and its lagging extremly. When you open the camcorder sometimes the device reboots , only god knows why they call these roms stable .... they should be called alpha or beta.

So guys here is the conclusion: i recommend to use stock rom (4.0.4 or 4.0.3) for this device or stock based roms . Jelly bean roms still have a lot of problems
