Thanks mattman for this guide

I've been looking todo this for about 2 weeks now, i finally have the time. I'm using 2.3.5 (i didn't know at the time i let it update) and win7 64. I've noticed several people have issues rooting 2.3.5, and also using win7.

Has anyone been able to do this using 2.3.5 and win7 64 before I get started and get stuck halfway through this?

Thanks all.

Did you use the unbricking guide to downgrade to Gingerbread 1st before installing cwm?
[LG Nitro HD] TheNitroNoob:
Factory Reset

I am attempting to factory reset my phone. But when I do I get this error and I have to pull the battery out and restart. The error is below

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

[15900] Secure Boot error!

[15900] Cause : boot certification verify

[15910]

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

Enter the FastBoot...

Enter the Fastboot...

Long time no see!
[LG Nitro HD] Swetnes:
By asking the same question twice you are not going to get a different answer. You got the secure boot error because you installed custom recovery from ICS and not Gingerbread. Start this guide over and this time install the v10 kdz file BEFORE you attempt to install a custom recovery like cwm. THE REASON: LG has a locked boot loader in ICS but not Gingerbread, hence you have to downgrade.
[LG Nitro HD] TheNitroNoob:
Okay thank you so much. I understand now. I also want to know if its possible to revert back to Stock ICS?
[LG Nitro HD] Swetnes:
Yes you can, you can either install one of several ROMs based on stock that are installable via cwm or if you want to revert to 100% stock, no root or custom recovery you can use the lg update tool, just click on help, then emergency. Hope this helps.
[LG Nitro HD] danis1997:
i cant make the progress bar pass de 4% :/ i make all the points many times and same stuck at 4%
[LG Nitro HD] audit13:
If your phone is soft bricked, try using the LG update tool to bring it back to stock and start over.
[LG Nitro HD] danis1997:
Yes, the problem is that when I use LG update tool it stucks at 4%
[LG Nitro HD] audit13:
Are you flashing in emergency mode?
[LG Nitro HD] danis1997:
Yes I am I try:

CDMA-Emergency

I try all possible combinations
[LG Nitro HD] audit13:
All I can recommend is trying the emergency mode with att firmware. When I was having trouble, this was the only firmware that would boot on my phone.
[LG Nitro HD] danis1997:
Is there any precaution if I flash ics or if I flash GB??
[LG Nitro HD] audit13:
I flashed ICS without taking any precautions as my phone was already bricked and would not boot.
[LG Nitro HD] LilLowEK:
Hi everyone,

I attempted this guide this weekend with no success. It failed to even allow me to copy the Android folder to my c drive. It wouldn't let me copy that folder any where to be honest. I even tried a windows xp machine. It states it has to skip files. Any clue?

Thanks,

Jeremy
[LG Nitro HD] mattman86:
Are you using 7-zip?
[LG Nitro HD] LilLowEK:
I have 7-zip installed. However I didn't manage the folder with it. I simply double clicked it to drag/drop. I'll attempt this soon. Very good idea! Thanks!!
[LG Nitro HD] mattman86:
Yeah, I created the zip with 7-zip and a few pages back, somebody was having a similar issue and 7-zip took care of it for them.
[LG Nitro HD] LilLowEK:
Thanks for the prompt reply. I'm not sure if I'll have time to try this tonight. I'll post the results when I do though!

Thanks again!

Jeremy
[LG Nitro HD] LilLowEK:
Thanks. Using 7zip it allowed me to copy them fine. I'll probably try this guide again this week!!
[LG Nitro HD] LilLowEK:
Hey guys. I've been working on this for a while. My biggest mistake was when running the B2CAppSetup.exe I was running it's software as it said I was out of date. I finally figured out you just close it to move onto the test. I also then couldn't get it to boot into the option where I choose english. After reading many pages here I saw a command I had to type. It worked flawlessly. However, now I'm stuck on download at 30%. I let it sit for over 35 minutes and it didn't budge. I canceled it. Started everything over and still at 30%.

Suggestions?

---------- Post added at 12:35 PM ---------- Previous post was at 12:18 PM ----------

I unplugged the phone to see if Gingerbread installed. It did not. I did a factory reset on the phone. Closed all pc programs. Ran them all again as admin. This time I set phone mode to cs_emergency. Started again. Here I am froze at 30% on download.

Anyone??

Windows 7 64 bit.

One more note. I have my sd card and sim card removed. One of the posts in this thread stated that resolved an issue.

---------- Post added at 12:59 PM ---------- Previous post was at 12:35 PM ----------

Oops. I said Gingerbread. But I'm at the end of the un-bricking procedure. Still at 30% download. "uncompressing files" It's been 27 minutes and counting.

---------- Post added at 01:05 PM ---------- Previous post was at 12:59 PM ----------

Woah! It finally left 30% straight to 80%. It's now doing the update. It past the dreaded 4% mark too!

---------- Post added at 02:02 PM ---------- Previous post was at 01:05 PM ----------

My newest problem of many. I have the phone rooted. Super User is in applications on Gingerbread. However when I go to flash the AT&T stock rom it tells me the device cannot be found by using the commands. I forget what the prompt was in dos before. However it's not the standard C:\Users etc. I don't recall this being there ealier.

Anyone? Btw, sorry for the pain!
[LG Nitro HD] LilLowEK:
Well. After a few headaches I finally got this done. I just got done with my back up as well. Now to try to figure out how to install CyanogenMod!

Some of the biggest problems I had are below.

- When opening the first LG program I kept going through the software install. This really killed every attempt of mine.

- After gingerbread was installed usb under development kept disabling itself after restart. You also cannot enable it unless you have your phone in usb software mode.

Thanks everyone! Any suggestions on a great rom other than CyanogenMod or how to install CyanogenMod please send it my way!

---------- Post added at 03:45 PM ---------- Previous post was at 03:03 PM ----------

CyanogenMod installed. I might check out the Liquid Nitro build though. Now to figure out how to install google apps! Does Liquid Nitro come with google apps? I'm guessing no due to licensing?

---------- Post added at 04:12 PM ---------- Previous post was at 03:45 PM ----------

Google apps installed. Easy. I just booted into the recovery section and installed the zip from there. Thanks to everyone! I'm not convinced I'm going to stay on CyanogenMod. I really think I'm going to check out Liquid Nitro. I kind of miss the old feel already. We will see if I can adapt!

Thanks again!!!
[LG Nitro HD] audit13:
Liquid Nitro includes the required apps go Gapps is not required.

I like Avatar Rom which is based on 4.2.2. I also use PurePerformance and Wind Kernel for get great speed and battery life.
[LG Nitro HD] NickBurger:
SuperOneClick 2.3.2 required, but 2.3.3 provided!

This guide is recommended by the CyanogenMod wiki for the LG P930 Nitro.

Everything works well enough, although there are a number of minor issues along the way. However, there is a show stopper. SuperOneClick 2.3.3 seems to work about 1 in 3 times, ending with a message that the phone was rooted and it was rebooting with root. However, the super user app was never installed and su didn't work in the adb shell (permission denied).

I banged my head against this for hours before stumbling on the stickied guide in this forum. It is *much* better in several ways, but most importantly, it warns that SuperOneClick 2.3.3 *does not work with the LG P930*. I downloaded 2.3.2, per the instructions there and from the link there. SuperOneClick 2.3.2 worked on the first try. It got as far as with 2.3.3 above, but then continued through several more steps including confirmation that the root was successful. I have now successfully rooted and installed CWM and CW 10.1.2.
[LG Nitro HD] chortiman:
The guide worked perfectly!!

After following the guide I installed Cyanogenmod 10.2 and I wonder if somebody can help me with this doubts:

I realized Cyanogenmod do not include Google Play nor any Google App, so I found that they can be downloaded and installed the same way I installed the CM Rom but my pc do not allow me to transfer zip files to de MicroSD!!!! The pc show the cell phone as a "music device" and shows a message saying something like: "the file are not compatible with your device"

Can somebody help this noob???

Thank you guys!!
[LG Nitro HD] audit13:
I don't recall exactly but can't you mount the sd card as usb in cwm under mounts and storage? If not, is there a way to change to mtp in order to transfer files?

Help with unbricking

I am running the ics leak 4.0.3 rooted; also .flashed clockwork mod recovery 5.8.2.0 in rom manager. but I currently cannot unbrick from the unbrick guide at the top of the general posts nor can I unbrick from this file method. Lg flash tool always returns latest software-no update needed, I followed both instruction guides to the the "T". modified the hosts.txt file. flushed the dns, the whole nine--Is there a self-extracting rom/program that can downgrade automatically or flash custom rom for customer recoveries? (when I attempt recovery goes to fastboot) Or can u post a video of the process; just to be absolutely clear on the processes of completing the unbricking? ty in advance -- I'm a total noob with android --1st android phone. :confused:
[LG Nitro HD] mith13:
u are the man bro..

i am exactly at the same spot, both unbricking process is no go for me..

was going to ask for a video guide to follow through, tried all the changes here and there but no luck-running win 7 64X don't know if that's causing it.

and i just wanted to check if we could try CM10 preview-rooting with tspark root and clockwork recovery with ics leak.

np hope we get some quick expert responses !!

i am running windows vista ultimate 64 -- i have also tried this as well with the tot file, but no luck either

@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.

Might want to add in the guide to set the type to CDMA under the Select Type at the top left corner of the UpTestEx tool. If you don't have this set, then the CSE Upgrade option doesn't appear.

Also these pictures help:

[LG Nitro HD] JINXR:
Make sure when you save the host file that you save it without an extension. So don't add .txt or anything to the end of it.

From your symptoms, it doesn't sound like your host file is setup, and I'd bet money that it's because you changed it to a text file because NotePad automatically tries to add it for you. Windows will create a new one if this happens so you'll probably see two files in there now, one "host" and the other "host.txt".
[LG Nitro HD] ynotdmf:
host file help

u r absolutely correct --I do have 2 host files now-1 is a hosts.txt -how do i correct it. delete file-redownload & setup host file? ty in advance :crying:
[LG Nitro HD] mith13:
Finnaly got it working

my friend i finally got it through the trick was not to close the pop up window that appeared stating now the app is working in evo mode only 3 users will be allowed while running the https.exe(shttps folder) file..and make sure you run every thing in admin mode by right clicking on mouse.
[LG Nitro HD] mattman86:
Just delete the 'hosts' file and rename 'hosts.txt' to 'hosts'.

ty for the input

I will attempt correction & advise of results. ty again
[LG Nitro HD] jowe11:
I have used the unbricking method in this thread and I have both of those. It should work fine if you follow the steps closely.
[LG Nitro HD] mith13:
alright u did it all good now just few more changes to go...

1st:- run the shttp3.exe in admin mode by right clicking..

2nd: clink i agree all and also update entry in main menu(so u can see the folder it is extracted to) and add to start up(it auto pops up on start up and gives to first privilege)..

3rd:-now extract the www.zip forlder to C:\shttps folder(make sure u have the files inside the www.zip inside the shttp folder *this is important as it contains the info to launch the the tools to act like a mini server"Were we both went wrong figured it out after a million try's"). check the screen shot to get a better idea.

4th:-now flush the DNS in cmd.exe right click and run in admin and restart the pc.,

5th:-now when pc starts up shttps should show up on start up-now do not i repeat do not close any pop up-just click on show desk top to minimize it(check the screenshot for pop up info)..

6th:now run the UpTestEX_mod2_marwin.exe and follow the guide..

Any doubt just let mew know we are going to get this through..:cowboy:

I added an alternate link to Google Drive.
[LG Nitro HD] Flyview:
You think I didn't try? About 10 times?

I repeat, a CWM backup (nandroid) will not unbrick the problem many of us had after changing SD cards. You will need to follow the full unbricking guide.
[LG Nitro HD] mattman86:
Why are you changing the SD card and trying to restore? Of course that won't work.
[LG Nitro HD] mattman86:
It just unbricked mine this morning.
[LG Nitro HD] Malnilion:
You don't understand. The problem that he was having was not fixable in CWM. It was some kind of corruption in a partition that CWM doesn't backup.
[LG Nitro HD] mith13:
did u get any pop up on start up?..

and let me c if i can create a video guide..

Keep getting stuck at step 4 phone just reboots without upgrading...
[LG Nitro HD] JINXR:
Make sure you're using the LG USB cord and plug it in directly to the computer. Don't use any USB hubs.
[LG Nitro HD] Childofthehorn:
Yeah. Mine gets closed at the 4% even done EXACTLY and with multiple tries and tried small changes as well.

I keep getting the darn Page_Error issue. Then if connected to the internet, it just skips over the update.

I am pretty sure that its an issue with the shttps server, which does show activity for redirecting on port 9002 for 127.xxxxx.

Before you ask, yes I have added the line to the Hosts file and run the dns flush several times.

Figured out how to stop that problem.

AS SOON AS YOU SEE THE LG TOOL SAY "_isConnected" DISCONNECT YOUR DEVICE!

Wait for the LG to stall at 4% for a moment and hook up your device again back to the computer in Download mode.

BOOM! Watch it progress and finish! You just gave it no opportunity to confirm the device against the model.dll

I just wanted to say thanks for this post .. even I was able to follow and fix my screw up.

I'd give you a thanks but not sure how ...

I followed this exactly and it worked. Thank you so much. I totally like CM9 more than the dumb official LG Nitro HD ICS rom.

Thank U Soooo Much!!

Worked PERFECT!

I know this process is a little long but it DOES work! GREAT JOB mattman86. :victory:
[LG Nitro HD] lowlab:
Would this process work for rooting 2.3.5 V10j ? I am not bricked nor anything , i read some where that this is the easiest medium to root 2.3.5 V10j .Any advice ?
[LG Nitro HD] mattman86:
The Rooting section should work for 2.3.5.
[LG Nitro HD] lowlab:
Tried it multiple times ,seems not to work for 2.3.5 V10j, the rooting section. Do you think i should update to Official ICS and try then?
[LG Nitro HD] drumist:
You can't root V10j easily at all. I think the people who have root with V10j actually rooted with V10f then applied the OTA update, which didn't remove root. But if you don't already have root, it's hard to get it with V10j.

That's the point of the first part of the guide in the first post -- to install the Korean V10f ROM, which is easily rootable.
[LG Nitro HD] lowlab:
So treat it as a bricked phone and do the whole unbricking process to root v10j ? Any parts i can skip?
[LG Nitro HD] drumist:
Depends, what ROM do you want to end up with?
[LG Nitro HD] lowlab:
I would like to use JB ,if possible.I read that theres a almost stable version going around.
[LG Nitro HD] drumist:
You'll want to follow the instructions in the OP of this thread up to and including the part "Installing ClockWorkMod Recovery". Then you can flash the JB ROM using CWM.
[LG Nitro HD] lowlab:
Thank you for the pointing me where to go .Quick question ,so install CWM through ROM manager to avoid ending in CWM loops?
[LG Nitro HD] drumist:
I don't know what you mean by CWM loops, but you don't have to install CWM through ROM Manager. It's just easier and not really anything you can screw up by doing it that way.

Edit: Oh, I think I know what you're talking about. CWM will install fine as long as you are installing it from a Gingerbread ROM. The problems that people have with CWM are when they root an ICS ROM, then try to install it.
[LG Nitro HD] lowlab:
So am getting up to 90% and its says Communication problem? trying connected directly to the back usbs of the Motherboard. Im at 46% if it fails do i have to start again from step 23? or just hit restart ?

Ok so I went from Stock ATT 2.5.6 V10J to ATT STOCK V10F ,Rooted . So acouple WOOT WOOT are in order.Thankyou Guy so much for your help.Now Im on to installing CWM. So yeah its long,very long but this is a proven method to rooting 2.5.6 V10J .

Hi,

I am having trouble with my Nitro HD. Now I am running official ICS which is also rooted.

But I want to install custom rom like CyanogenMOD 9, so I need custom recovery....

The problem is that this guide is not working for me!

Everything it's OK but when LG Phone Update program passes from "download" to "update", my phone leaves Download Mode and boot's up to ICS. Obviously nothing changes because it does not flash anything...

I am running 32bit Windows XP and followed the guide, letter by letter.
[LG Nitro HD] MGA2009:

Nevermind... I unistalled every driver and reinstalled it. Now it worked.

Running CyanogenMOD9.

Unistalling drivers and installing the ones that come with the zip is the key to a smooth process.
[LG Nitro HD] Utacka:
lol finally it worked, got stuck at 4% and scrubs was on tv so i just ignored the phone, then after 30 min i saw the phone was rebooted but it was still 4%.. ah well! running cm9 now! I believe my p936 got software-bricked in maj/june....

am I the only one that has "normal web upgrade test" and no CSE Web Upgrade test?

I had that issue before, but after reinstalling windows 7 sp1 64bit it suddenly appeared :o

So I'm guessing this doesn't work on Windows 8 then? has anyone found a workaround?
[LG Nitro HD] Malnilion:
I was able to use the unbrick method with only minor graphical errors in Windows 8.
[LG Nitro HD] cashy57:
Did your's show the cse web upgrade test button? I tried the normal web upgrade option and got through everything except once the upgrade completed, it would get stuck at the optimus lte screen. I have a p930 that was running v20c before I tried to unbrick and now reverted back to v20c again because I can't get to 10c.
[LG Nitro HD] zikario507:
everything work fine..

now i'm on Ginger bread 2.3.5 rooted and with CWM, i would like to know 3 things:

1- if i install CM9 official, and then i would like to go back to the V20c Flash with CWM, i got rooted too?

2- How can i flash to the V20c offiacly by Hono! from my present rom "gingerbread"

3- how can i loose the rooted fix?
[LG Nitro HD] drumist:
HO!NO!'s CWM-flashable version of V20c is already rooted for you. Flashing is the same as any ROM.
[LG Nitro HD] zikario507:
so ill have to format data cache factory reset? before od the installation of v20c hono flashable?
[LG Nitro HD] rani9990:
Yes.
[LG Nitro HD] kenship:
I have a backup of CM9 (Full Throttle 8.3) and want to get back to it from Bell ICS. Does it matter which kdz I flash and the img files I load during the unbrick process?

What I mean is: if I restore my backup afterwards it would wipe everything, including the 5 img files, wouldn't it?
[LG Nitro HD] neuty:
I need help please...My update wont get past the 93%...

I had to unbrick because my sound stopped working and the phone got super slow...maybe its hard bricked...

SAYS PROBLEM WITH COMMUNICATION BETWEEN PHONE AND PC

EDIT: i was able to skip this part since i was rooted already, so i just copied the images to my sd card and cmd'd away. Phew...
[LG Nitro HD] drumist:
It won't overwrite your baseband/firmware images, which means the ones you will end up with will be the ones that you installed during the unbricking process. So you may want to manually pick the ones you want to install. (You can simply use the ones you want in place of the firmware/baseband images that the unbricking guide tells you to use.) If you're on AT&T, use V10j or V10f (unbricking guide installs V10f).

Boot/system will be replaced when you perform the restore of your backup, and the recovery partition is overwritten when you install CWM.
[LG Nitro HD] RealyPssd:
Trying this guide to unbrick my phone so I can try the CWM version of the Bell ICS release.

When it's updating, 2 times now, the Update Software has lost the connection with my phone around 90%.. The USB cable has not been touched at all.

My phone's screen is still on showing the download mode picture..

I have copied all of the text in the box at the bottom of the update window if that'll help..

EDIT:

Tried again and it worked..

Rooted using the .bat file and it said it worked...\

Trying to connect to my WIFI to attach my google account and install CWM via ROM Manager... WIFI app is horribly slow on the Korean ROM... I cannot connect to my WIFI...

Maybe I'll just get to the Stock AT&T GB and do it that way
[LG Nitro HD] Malnilion:
You won't be able to get WiFi working on the su640 ROM. You need to flash the nitro .img's first.
[LG Nitro HD] kenship:
Exactly, tried it last night, need to flash AT&T img files to make it work.
