OK I got all the way to the end....Now when i supposedly it was going to boot into ATT Stock rom....Im stuck on lock screen..HELP!
[LG Nitro HD] audit13:
Did you get CWM installed?

Just in case I could not book into the stock ATT rom, I copied a few different roms onto my SD card so I could boot into Recovery and load any of the other roms.

What OS are you using? I used XP 32 bit and didn't have and problem. Maybe start from the beginning and see what happens.
[LG Nitro HD] redstar299:

I using XP 32 bit too...This happened when I was trying to flash the ATT Stock Rom.. I put those commands in an it said wait to boot into the rom but now its stuck on the home screen
[LG Nitro HD] jalal.mustafa:
i m using windows 7 32. also tried on windows 8 32bit. . .

another question.: how to install CWM for su640 on ICS V20d (update online via LG support tool) . i have just rooted v20d. is this same as gingerbread or this should be installed on different partiton?
[LG Nitro HD] Swetnes:
Power off the phone, hold down volume down and power. There will be white text telling you to hit power twice to do a factory reset. Then when you reboot it will boot fine. This is a commonly missed step.

---------- Post added at 03:01 PM ---------- Previous post was at 02:58 PM ----------

Actually you can and there are plenty of threads on it you just have to do it from v18f then go to v20. Now the above is true if you want a custom recovery due to the locked boot loader.

He said ATT Stock rom, so I assumed v20, v18 is the unofficial leaked ICS, correct? But alone yes my statement by itself is wrong, I could have said "You cannot root officially released stock ICS"

[LG Nitro HD] nicksavop:
could someone help. Im in download mode but every time it gets to 90% i get the "problem with communication between cell phone and PC" and have to restart with the same results.
[LG Nitro HD] mattman86:
Are you able to just reboot the phone and go into the AT&T ROM? I've had that happen to me a few times and it still worked.
[LG Nitro HD] audit13:
Are you able to get into recovery mode at all? I know it recommends that you boot into the stock ATT rom but maybe you can get into recovery mode and flash a different rom such as Liquid Nitro.
[LG Nitro HD] Malonkas:
for me , the brick is hard.

I have flashed the wrong firmware.

The phone will not torn on!

so download mode, is not an option ( far as i know)

Is there a way, to make it torn on?
[LG Nitro HD] Swetnes:
What happens when you hold down volume up and plug in the usb cable into the computer?
[LG Nitro HD] Malonkas:
When I plugged in the USB and hold down the volume up, or down.

The capacitive icon in the bottom of the lg is turning on and of repeatedly.

The Win7 recognize the device as "usb device".

So that is good, when it will be not even torn on!
[LG Nitro HD] Swetnes:
Maybe? Go to this website to see if it will do an install of v20c. If it does this will return you to 100% stock and then you can go from there.

http://m.lg.com/us/mobile-phones/ATT_Update/index.jsp
[LG Nitro HD] Malonkas:
thank you for response.

I tryed that, and the phone not responding!

btw.. it flashing the capacitive bottoms, even when I plug the device.. with out holding any button.

what else??
[LG Nitro HD] Swetnes:
Well unless someone else has some ideas you may have to send it in to have them restore the phone. If it's an AT&T nitro you should be able to get it taken care of if you go into an AT&T store.
[LG Nitro HD] drumist:
Flashing capacitive buttons means your battery is too low for the phone to even turn on. You need to leave the phone plugged into a wall charger for a while, then try again.

By the way, which firmware did you install?
[LG Nitro HD] Malonkas:
flashing buttoms by flashing the wrong rom..

About the firmware .. I dont remmeber.. sad.

The Flashing capacitive buttons are flashing.. but when that happend (the firmware flashing) it was a few days ago, and it was on 100 precent.
[LG Nitro HD] drumist:
Then I don't know. If you can't access download mode, there's really not much hope of fixing it yourself.

I could fix it, but it will cost me around 40-100 us ...

So I need to send it, and wait for the repair.

And from here, the middel east, it is quite hard . And cost quite a lot of money :rolleyes:

Bricked LG Nitro HD (P930)

First, I appreciate the work you put into the thread for unbricking. However it didn't resolve my unique "bricked" issue and was wondering if you could assist?

My issue is that the phone boots up to the LG screen then reads "security error". I can put the phone into download mode but as I tried to use your described method for installing the .kdz, the LG updater reads "most current version installed no update necessary". I have exhaustively tried to flash this pig to no avail. Is there a way to wipe the existing ROM from the phone?

Any help you could offer would greatly assist.
[LG Nitro HD] drumist:
First, just try doing a factory reset. With the phone turned completely off, hold down the volume down and power buttons at the same time. Keep holding until you see text on the screen asking if you want to perform a factory reset. When it appears, let go and then press the power button twice to confirm. The phone should reboot normally.

If that doesn't fix your problem, the easiest way to reflash the ROM is to first downgrade by downloading this file and running it to install the v18f version to your phone.

It will look a lot like the official ICS ROM but you shouldn't leave it with that version because it's buggy. However, once you have v18f installed, the normal LG updater will recognize your phone is out of date and will allow you to update it again normally.

Hope that helps!
[LG Nitro HD] Hutch89:
Did it work?
[LG Nitro HD] punk_zappa:
Will this work for V20f? Thanks.
[LG Nitro HD] nss007:
Hi

my phone is at&t nitro hd (p930) , it has stock ICS 4.0.4 v20c rom and its ROOT

i wana back to stock 2.3.5

can i do this without unbrick method and using only this instruction with terminal emulator app in phone ??

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

Flashing AT&T Stock ROM1.Once the phone reboots, type “cmd” in the ‘Run…’ dialog and press enter.

2.Type “adb shell” and press enter.

3.Type “su” and press enter.

4.Run the following commands one by one in order:

Code:

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

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

my second question is that what will happen if i use v10j baseband in v20c rom ???
[LG Nitro HD] Swetnes:
I would have to second that I also couldn't get it to work unless I had the HOSTS file as above.

EDIT: I didn't realize I was on the first page lol.
[LG Nitro HD] JGLChilly:
I followed the instructions precisely using a rooted leaked ICS P930 and an Acer 10.1 Netbook (32 bit single core Intel Atom processor) running Windows 7 Home Premium 32 bit.

Worked like a charm!

Then I tried out JellyBam (lame) and now ParanoidAndroid. ParanoidAndroid is simply great!
[LG Nitro HD] lordcheeto03:
Glad to hear it worked! Also, I don't want to start some nonsensical debate or clutter this thread too much... but how exactly is JellyBam lame yet ParanoidAndroid great? JellyBam does everything that PA does with the addition of the AOKP settings... I'm merely curious.
[LG Nitro HD] TheCrow1372:
DAMN man, what is wrong with JellyBam :( cuz it looks SWEET especially on YouTube so what did you not like and what issues with it?
[LG Nitro HD] mattman86:
I particularly found that some settings between the ROMs don't really interact very well. Some settings of PA are overridden by CM or AOKP and vice versa. Slightly annoying.
[LG Nitro HD] JGLChilly:
FYI - The detailed instructions in this thread for unbricking are outstanding! I followed them and it worked :) Perhaps JellyBam's instructions were unclear. I tried the 12/15 version and it lacked at least the GAPPS/Play Store. I likely did something wrong, maybe even didn't follow the instructions precisely... However, I do see that there is a new stable v3 of JellyBam up as of today. I'll try that!

Thank you MattMan for teaching me how to unbrick and play with custom ROMs!
[LG Nitro HD] Swetnes:
You have to install gapps...seperate download... www.goo.im and click on gapps for the version of android you are running. With the exception of JELLYBAM v3.x ALL versions of CM require install of GAPPS.

[LG Nitro HD] jurassic512:
Can you describe how it was bricked and what symptoms you had? My "Nitro" is also bricked and I would rather not have to send it away to get fixed.
[LG Nitro HD] lordcheeto03:
What's your phone doing that it isn't supposed to; or not doing that it IS supposed to... you might be able to follow one of these unbrick guides and not have to send it off to get fixed.
[LG Nitro HD] jurassic512:
That would be sweet. A jtag will cost me $80 plus shipping. My phone will not power on. Not even the buttons at the bottom light up. When I connect to a Windows 7 PC via USB (I have the proper LG drivers installed), the notification bubble in my system tray says: QHUSB_DLOAD instead of the LG Driver name you get after installation. I flashed a JB 4.1.2 custom ROM AND kernel clearly marked for another phone (i9100), and after a restart, I get a black screen. Bricked. Any help would be appreciated.
[LG Nitro HD] drumist:
This guide won't be useful unless you can get to download mode.
[LG Nitro HD] lordcheeto03:
You can try putting it into download mode (hold volume up while you plug it into a computer). If you have download mode, you can follow an unbrick guide; otherwise, you have a nice, shiny brick until you send it in.

Moral of the story: don't install a ROM unless it's for your device.
[LG Nitro HD] mark8503:
Can just skip to the root part? My phone is on 2.3.5, also when I do root, I just double click on the batch file and it automatically runs?
[LG Nitro HD] lordcheeto03:
If you're running stock GB, as in never upgraded to ICS, then all you need to do is root. No need to flash the stock AT&T stock rom, just go ahead and install CWM. Although, my understanding is that you will not be able to use any of the stock/rooted CWM flashsable ICS roms. Everything else should work fine though.

The root method should work, but if you haven't downloaded the .rar yet, there are other one-click methods, much smaller than ~700MB to root stock GB.
[LG Nitro HD] mark8503:
I tried a different method from here

http://smartfoneninja.com/easiest-way-of-rooting-and-installing-cwm-on-your-lg-nitro-hd-p930/

But it didn't do anything or I didn't do it right.

When I use this method though I just click the batch file while the phone is in mass storage with USB debugging?
[LG Nitro HD] lordcheeto03:
I do believe you have to be in PC software mode, USB debugging enabled, and have "unknown sources" checked in the security tab.
[LG Nitro HD] Swetnes:
Nope not true once CWM is installed you can install ANY ROM made for the Nitro. Now it is true the recovery partition can only be installed in GB due to the locked bootloader in official ICS. However once the CWM recovery partition is installed from GB you don't have to worry about it since CWM ROM's and backups don't touch the boot loader.
[LG Nitro HD] lordcheeto03:
I agree with you, it SHOULD work. I just read HONO's V20c thread and there were a lot of people saying the stock ROMs will get stuck on the LG logo if they haven't unbricked; so the general consensus in that thread and also his ICS leak is that unbricking, even if you already have a custom recovery installed, is required to install any of the stock CWM Flashable ICS roms.
[LG Nitro HD] mark8503:
I tried to Run the batch file from the root folder of the op's download but it gave me a bunch of fails and denials. I'm on stock 2.3.5
[LG Nitro HD] lordcheeto03:
Try to find superoneclick. That should do the trick
[LG Nitro HD] Swetnes:
That's usually solved by doing a full wipe AFTER installing HONO's v20c. Also if coming from CM9/10 I recommend formatting the system partition BEFORE installing. Also FYI unless someone is coming from the original v10f that shipped with the Nitro in 2011 THE only way to get CWM is to unbrick first. Therefore the only way to install any zip ROM requires unbricking first.
[LG Nitro HD] mark8503:
Just Google it or is that on xda?
[LG Nitro HD] s8freak:
How in blue blazes can you unbrick a phone that won't even power on?? No download screen or anything?? Is that even possible? I've hard bricked two S3's in my stupidity of not reading or making sure what I was flashing was specifically for my phone. Now I'm VERY careful and know my limitations.
[LG Nitro HD] lordcheeto03:
Both. There should be some links buried around this forum, not exactly sure which thread, but i'm sure it was here.

[LG Nitro HD] mark8503:
I'm trying to use super one click v2.3.3 but it keeps getting stuck at step 7 and not responding? Any ideas?
[LG Nitro HD] Swetnes:
I do believe you can only use v2.2 with the Nitro plus unless you are on the 2011 version of GB v10f it cannot be rooted, you must use the unbricking guide.
[LG Nitro HD] mark8503:
It says LG-P930-V10j-FEB-26-2012

Is that why nothing is working for me?
[LG Nitro HD] Swetnes:
Yes to my knowledge no one has been able to root that. I have a .tot of v10j that I know I could root if I could ever find how to install. Unfortunately the software tools I need are now just dead links. I do digress, I am assuming you want to root to install cwm? Use the unbricking method that starts with installing ics leak.
[LG Nitro HD] mark8503:
Yeah, all I want to do is put on clockwork but as far as I know it has to be done with ROM manager. Isn't there a way I can install cwm with fastboot so I don't have to root?

I didn't skip any steps. Step 24 is the one that doesn't seem to be working. When I run that file it comes up with an lg logo and says installing, its real quick though, only about two seconds. Is that how quick it installed when you did it? Anyway when I hit the start update that is what it is telling me needs to be installed but it already is.

I'm gonna check out the other guide you linked also.
[LG Nitro HD] lordcheeto03:
Oh, I gotcha. Well, when you're updating, did you fully close it or did you just close it to the taskbar? By 'it', I of course mean b2 app or somethin.
[LG Nitro HD] mark8503:
It doesn't open it gets installed at step 24. I double click on the exe, it pops up to make changes and I hit yes, fast forward to start update and it says I need to install that tool.

When it says close it in step 24 does it mean the folder it came from or the tool? As far as I see the tool isn't open.

Have you ever done the steps in this guide?
[LG Nitro HD] lordcheeto03:
Yes, I have used this guide. In fact, I used it tonight to try something out... I didn't have any problems. Did you end up having to install msxml.msi? I recall it saying that if you encounter any errors with uptest that you should install that file. I assume your error is with uptest and not b2capp; although it's saying b2c isn't installed.

Ok guys i have some questions before i take the plunge root my LG SU640.

I previously had a galaxy s and have some basic knowledge of rooting and installing roms.

My questions are:

1)Will this guide work for SU640? I mean i dont have to download any additional files and this guide will create no errors?

2)After rooting my device can i unistall the bloatware?

3)After rooting can i update my phone through the lg software? (cause on SGS if you update a rooted phone through KIES you would brick it)

Also can P930 roms work on SU640? i mean they both phones are practically the same.

Not Sure why CWM isnt booting?

cause: boot certification verify then it says enter the fastboot enter the fastboot? What is this about and how to I get into bloody cwm to flash CM10.1?
[LG Nitro HD] Swetnes:
That's because you skipped a step and installed CWM in ics. LG has a locked bootloader and so you have to downgrade to Gingerbread first.
