WORKS!

Had to do a battery pull and factory reset to stop boot loop after AfterROOT didn't stop it.

Great guide. Aparently TPSparkyRoot.bat didn't root my phone but i kept going with the steps until i got to the part where i was to flash the GB ROM and it took too long (71 tries) before i pulled the battery only to power on into download mode. thankfully starting back at step one got me back to 18f, and i got root to pass and now i'm rooted running CM10.1 nightly.

Thanks again. This LG is the third phone i've used XDA for to flash custom roms. Best community ever.

So far this method has been working perfectly well... Until I get to the part where I've got to install B2CAppSetup. The install process just sits there, the progress bar having barely started. I am running Windows 7 64, I've tried installing it in compatibility mode, as administrator, and nothing. In the task manager I can see that the process is using 0% of the CPU, so.... I'm not sure what I can do at this point. I'm still reading through this whole thread, but I was hoping someone might know what to do. Any suggestions?
[LG Nitro HD] Swetnes:
Did you install msxml first?
[LG Nitro HD] yorkeandvedder:
Yes. I actually worked around the issue using a different version of the same program. Now I'm stuck at the recovery portion of the process. Got CM 10.1 all ready to go in the SD card, but whenever I reboot in recovery mode, CMW can't "see" the zip file. If I choose the "install zip from sdcard", it says "file not found", won't even let me the root directory. I've tried renaming the CM10.1 zip file "update.zip", to see if the "apply /sdcard/update.zip" would work, but nothing.

I've reformatted the SD card; Windows has no problem seeing the card, neither does Android (ES file explorer).

I've done some research, and found out that there may be a problem with the touch version of CMW that causes this error. Weird thing is, I installed the regular version, never upgraded to the touch version. Yet, when booting into recovery mode, I *can* navigate through touch, rather than using the volume/power buttons. I don't get why. Not sure if there is a way to get an older version of CMW that doesn't have the touch navigation.

Another possible cause (according to another post) was the size of the SD card. High capacity cards (e.g., 16 GB) have this issue while lower ones (e.g., 2 GB) don't. Unfortunately I don't have a smaller card now, so I'll have to get one to test this theory out.

Unless anyone else has any suggestions? I've also tried installing CM 10.1 directly through the CMW app (automatic reboot into recovery mode and ROM install), but the script fails.

Thanks.
[LG Nitro HD] Swetnes:
You were correct with your initial analysis but used the wrong program. I am assuming since you tried formating in windows you have a backup. This is what the issue is:

LG uses an unusual format on its SD card. It doesn't prevent windows, android, android apps, etc from reading the card but cwm cannot hence the problem. Use the following app to format your SD card with default settings and restore your backup. You will no longer have any issues:

I just read this post I have a 64gb SD card in my phone the fast one when I got my card I just put it in and format it just cheak if cwm will read it it did

thank you so much for the guide . had some trouble the first couple of tries (windows 8) then decided to try it on my desktop (windows 7) . and it ran with out a problem . now i have a rooted lg p936 with cwm

That post only pertained to the lg supplied SD card that came with the nitro.
[LG Nitro HD] Eric.N:
Thanks!

Just want to write a quick thanks to you Hereric! This guide is the last of many that I had tried, and the only one to successfully allow me to root & rom my Nitro HD (P935). I had a problem connecting to my network, but a flash of the baseband using thes basebands below worked like a charm (I hope -- i had bars after flashing, yet to do a full debug).

I did have some trouble downloading the file from the Google Drive. The file kept failing half way through. If anyone else has these troubles, just keep trying! The download is sound.

Hey guys, i bought my phone off ebay its unlocked but it has the telus boot logo, i have rooted a phone before but it wasnt unlocked, my question is, id i root my phone and change my ROM will it get rid of my unlock?? I dont want to have to pay 50 bucks to get it unlocked again.. Im with BELL if that means anything lol LG Optimus 4g lte
[LG Nitro HD] yorkeandvedder:
First, a big THANK YOU. That formatter worked like a charm!

That said, I'm stuck again. After installing CM 10.1.2, the process hangs after rebooting from CWM. The phone gets stuck on the CM booting screen. I've tried reinstalling. I've wiped the phone's cache, delvik cache, reinstalled... CM has no problem installing through CWM, but I can't get past the spinning logo.

I'm researching the issue now, but any help on this would also be greatly appreciated.

Thanks again
[LG Nitro HD] Swetnes:
Have you tried a different version? Also are you running an alternative kernel, like wind kernel? Another thing even though its been a while since I ran cm10.1 I remember it taking a while with the initial boot and I mean about ten minutes.
[LG Nitro HD] yorkeandvedder:
As it turns out, all I had to do was include a FULL wipe as part of the process. Didn't really think it'd be necessary after doing the full root procedure, but... Goes to show what happens when I assume.

To answer your questions, though, I was getting ready to try an older version of CM 10, and no, not using a different kernel. And once I followed the proper procedure, CM's initial boot didn't even take that long (fortunately).

Thanks for all your help, though!
[LG Nitro HD] Jake1Jamie:
I'm getting stuck on step 14.."Once these settings are enabled, hit the "Launch Software Update" button." It continuously tells me "Can't find Model dll", so I can't even get to step 15 :confused::confused:
[LG Nitro HD] nizmoboy98:
Just leave it running it will complete step 14 .
[LG Nitro HD] Swetnes:
Something didn't get installed properly: Make sure you reboot after each step:

Install BC2 app, reboot

Install LG unified driver suite, reboot

Install msxml, reboot.

Then run the kdz installer, if you continue to have errors there is an alternate method.
[LG Nitro HD] nizmoboy98:
I had same thing happen to me on step 14 . then read somewhere I n xda that that's not an error . just leave it running till your phone bootloops . model.DLL (enter number here ) . if that's "the could not find" your having then just leaving it running .
[LG Nitro HD] Gladpants:
CWM not permanently installed.

I can only access CWM after initial install. I am unable to get back into it after a reboot.
[LG Nitro HD] fishline:
I'm also stuck on step 14. After clicking on "Launch software update", there are two lines, the second being "unpacking kdz" or something like that. After about a minute, the program simply disappears. No message or error. The phone stayed in download mode as if nothing had happened. I tried clicking on Read phone info before Launch software update, but tried it several times with exactly the same result. Those who found "other version of the same program", can you please post where to get it? This is AT&T P930 if that matters.
[LG Nitro HD] fishline:
Thanks for the link! I actually downloaded that and tried it, too, with the same result. What worked for me was moving from a Win7 machine to a WinXP box. Step 14 just kept giving me the errors like others had seen, but the phone did go into bootloop. I just ran afterroot.bat, and when that's done, disconnect the phone, pull the battery, and did a hard reset as described in step 15 and on. And it worked! Funny that the KDZ update program was still stuck where it was. Had to open task manager to kill it.

I'm now on the AvatarROM. Thanks to this guide and all those who helped posting tips on this thread!
[LG Nitro HD] Vicntc:
This seemed to work for the most part until I got to here. When I clicked on Launch, it started to run then after about 2min of trying to extract the KDZ file, Windows popped up and said MOD_something had stopped working and it was closing the program. I tried running under WindowsXP compatibility mode http://xdaforums.com/showthread.php?t=2149211 but no change. The phone did not reboot and did not go into a bootloop (just stayed in Download mode). Hoping it might have worked anyway, I rebooted and ran AfterROOT anyway followed by a factory reset. SU and FileRoot etc all appear to be installed. However...

When I try to access CWM via the steps above, all I get is a black screen with the LG logo and the following text...

[15900] --------------------------------------

[15900] Secure Boot error!

[15900] Cause : boot certification verify

[15910]

[15910] --------------------------------------

---------------------------------------------------------------------

Enter the FastBoot...

Enter the Fastboot...

Long time no see!

---------------------------------------------------------------------

The device is hung and requires a battery removal to restart.

I've downloaded CWM from the Market and tried to reload/update (since it says there is a newer version anyway)

If I try to reflash, it downloads the update and says it was successful however if I try to reboot into recovery mode I just get the above.

I am running Win7 x64 and using an LG Optimus 4G LTE (P935) from Telus (unlocked)
[LG Nitro HD] Vicntc:
I am using Windows 7 x64, an LG Optimus 4G LTE (P935) originally Telus now unlocked.

This is my second attempt since a search of similar threads seems to suggest the second times the charm...

Everything runs fine until this point (no errors, no blips, no coughs, etc.)

Sadly, I never get to here successfully. As such, it would appear I am stuck here since the P936 upgrade never happens.

Reading various threads here, one suggestion has been to run on a 32bit platform but I don't have one. Others have said it works fine in x64. At least mine is consistent that it always fails at the same place with the same error (see previous post). As good as Root is, I'd really like to be able to load a little CM on this and see how it goes.

Is it worth even running these if step 14 failed?

Here's hoping I can get here some day... :D

MY Su640 keeps on bootlooping...

Dear Developers...

:(

My SU640 keeps on bootlooping. I tried this guide several times. but no use. I'm using a windows xp and all went ok. Even pulling the battery and factory reset doesn't fix boot looping.. What may be wrong.... Any help advice.

Thank you.
[LG Nitro HD] Vicntc:
I'm not a developer and I don't play one on TV however did you see Step 15?

15 - After the update has run, the phone should bootloop on the second logo screen. While it does this, run AfterROOT.bat from the KeepRoot folder.
[LG Nitro HD] hiru555:
To Vicntc.

Dear Friend.. I did it.. First time It seems running and doing something. but after that it says No device found. The phone keeps rebooting continuously. even battery pull and factory reset doesn't correct this. The adb commands too don't work because the phone is not properly booted.

I tried this in Wind 7 and windows XP. All went perfectly till this step. I'll do this for a one last time.

EDIT....

Finally. after giving so much paint to the phone.. Now its working.. I downloaded the kdz file as in this Guide by Muhammad Ali

[LG Nitro HD] georgesovetov:
Thank you a lot! I reflashed my LG Nitro HD successfully!

It is quite good that package has been uploaded to Google Drive and that it was one package with all necessary programs.

My OS is Windows 7 x64 Enterprise.

Usually, I work as user with limited privileges, I ran all programs with elevation (administrator privileges).

Also, I have something to tell. There were some problems and issues which frightened me.

There were some non-english messages in this bat file and other ones. What is language, I do not know, but I want to understand what I am said. Although, I just pressed "any key" and it worked for me.

Here I stop. It seems, B2CAppSetup checks for updates in Internet, but does not actually say about this! I extensively use Windows Firewall to restrict application to use Internet until i permit it. So, I just stopped firewall service for a while. (It is boring to create firewall rule for this purpose.) I ran Resource Monitor and it showed me that installer was downloading something with low speed.

Also, I installed B2CAppSetup version from LG website, not from package.

After doing this and two log lines appeared (last one was about unpacking), program was marked as not responding in Resource Monitor and was closed by Windows in few seconds.

I tried to press Read Phone Info, close windows that appeared and press Launch Software Update.

I did not try to press Read Phone Info and then update button in newly appeared window right in this moment. I suppose now that this was worth to try.

Instead, I followed steps from 3 to 7 that are listed here and steps from 5 to 7 from this post which instructs to do what I had not tried before.

It should be said that bootloop was when progressbar reached 4% and log stops at messages with numbers 2004-99 and 2001-0. Also, I just followed instructions and it was alright.

So, that's all. Thank you again.
[LG Nitro HD] LilLowEK:
Hi everyone,

I followed this guide. However, when I was finished the phone wasn't rooted. I think the problem I had was at the following 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.

----------------------------

I ran the software, the red bar went across, and it opened the other LG software. However, this software said there was no update. I clicked the update button anyways as my phone wasn't restarting or looping. After it finished there was still nothing on the phone looping or stuck on the logo. I proceeded with step 15 anyways.

Can anyone shed some light on this?

Thanks,

Jeremy

Thanks for the guide, I know many people can following the guide without problem, but if you got communication problem in step5:

In my case, the Step 4 is causing problem, I have switched to Win XP, have all the driver installed, but communication always failed in download mode, but if I start the phone normally, and as instructed in step 5, select "PC Software" mode when USB connected, the phone update goes well, and during the update, the phone will indeed go to download mode itself.

HTH.

PS, if your phone is really brick, and can't boot, then above won't help. I need this unbrick to try some new ROM.

Hello,

And thanks in advance for any help.

When I run the TPSparkyRoot it says device not found and does not appear to do anything, (which may or may not be normal)

But The problem I am really having is when I run the KDZ it put down 2 lines of code and then does not respond, I cannot get any further and have even tried running the all the steps again and it yielded the same results (Definition of Insanity?)

Again any help is appreciated, as I'm trying to get this phone set up for use in Australia for my honeymoon.

I may have missed something here but from step 11 to 17, I followed the instruction to a T. But the end result after booting, I see my version to be V20F. I do have root after step 17 but when I try to install cwm via Play Store app or by using "dd" of the included recovery.img. I receive the security check error when I try to enter recovery mode.

When I flash, I have to click on Read Phone info. This method does not provide any logging. However I do see on the top hand corner, the model number V20F. During the flashing, there was a stage where it was downloading from the internet and then extracting. I should have not needed to download if it uses the V10F file locally.

Is it possible to force flashing V10F?

And what version should I see after the whole process?
