I was able to try on a windpws xp comp still no luck. I was up all last nite redoing the steps. Compatability mode didn't work either.
[LG Nitro HD] vitamindy:
My phone died after it got to 13%. After that it would not boot up no matter what i did. It registers as a usb input device now on windows. When I plug it into the computer the lights flash in specific patterns. I tried charging it but no dice. Anyone can point me in the right direction?

help me. my phone is brick with QHSUSB_DLOAD

how to unbrick my phone ( LU6200 LTE) with QHSUSB_DLOAD
[LG Nitro HD] lordcheeto03:
Send it back to LG. No way for the end user to fix that yet.

If I have CM10 already on my phone can I just skip to the "Restoring the original Nitro HD images" section?
[LG Nitro HD] Phk:
Hi, as soon as i do the Start Upgrade using the v10 KDZ and having the phone in download mode, it auto-reboots at 4%, and then the installer gets stuck at 93%

Nothing gets installed :(
[LG Nitro HD] NFleck:
For some people it will kinda freeze around the end, but it should stil be done. If during the unbrick section regarding the kdz; if the phone is rebooting and such, it's working properly. Just let it do it's thing. Sometimes it takes longer. However, if it's getting stuck at 4%, that can be a driver or connection problem. Check to make sure you've installed the correct drivers -- mobile united driver 3.8.1 (latest) -- I find doesn't work well for the unbrick. So if you've installed just the latest driver from the lg site, uninstall it via programs & features, and then install the drivers posted in the guide (united mobile 3.6, usb 1.0, and modem 1.0). Also try rebooting, and make sure you've followed the instructions to a "T".

Good luck.

I told my coworker I could help him root his phone- now I bricked it!

I successfully flashed P930_UDT_v18f_04112012 earlier on my work computer when I got to the KDZ tool crash (where I should have clicked read system info). I brought the package home while the phone was still in "download mode" but now it seems stuck in it- pulling out the battery doesn't work, it goes right back into download mode no matter what. I've figured out what I should be doing, but now the LG software is unable to connect to the phone, it says connectivity problem between phone and computer. ****! Could this be a USB driver issue? Or did I brick the phone so hard that it can't be recognized? Help!!!!
[LG Nitro HD] Namuna:
I would take that error about "problem between phone and computer" as a GOOD sign. It means the computer detects something there, but it's having problems communicating with it...Sounds like a driver issue to me.

Since you're now working from a different computer, I'd highly suggest starting the unbricking procedure from scratch.

Good luck!

i think i messed up my phone trying to restore original Nitro hd image. When i did the code (dd if=/sdcard/boot.img of=/dev/block/mmcblk0p8) it said there was no space to move the file... all the other codes worked fine though. Then when i went to the next step to put the phone in recovery, i turned off the phone but now it wont even boot anything..

My computer reads that a device has tried to connect, when i plug the usb. (it makes 3 downbeat sounds, as in the computer does not know what kind of device has been plugged in)... also as i hold the down and and power button to put into recovery my laptop makes a noise like it accepted the device but when i let go it makes those 3 downbeat sounds again)

It looks like my phone is completely bricked, but I want to make sure theres anything i can do about it.

EDIT: After waiting a while, my phone responds to the usb connection. Screen still stays off and wont turn on, but when plugged in usb, the notifications flash fast for about 5 seconds then turns off again. Wtf is going on

Was in your shoes 3 days ago. What you need to do 1st is install the ICS leak v18f, root it, flash 10f_00.kdz, run keep root, install CWM recovery then you can flash any custom ROM u like.

yes and in the process of doing it we got stuck in the fastboot loader menu.

cant even flash anything now cz the phone is stuck there and pc doesnt detect the phone other than in the download mode.

I just used lg tool to go back to official telus rom. The problem is that I have windows 7 64bit systrm. So I always get stuck here

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!)"

Tried diff pcsbut they all are 64bit

You could temporarily load a 32-bit version of Win7 using your Win7 x64 serial key in order to run through the process.

I've successfully unbricked several times -- first try -- using win 7 ultimate x64 each time.. You aren't following instructions.

hey guys so ive been using XDA for all my phones, seems to be once a month im buying anew one and just letting the old ones collect some dust

so heres my issues i have the Nitro hd p930 ive gone through this guys and others like it, ill run the UP testex and it always stalls at 4% ive tried on different computers and all sorts of variables following everthing the the letter, i was wondering if there is someone who can help me unbrick my phone in real time or to let me know if its even possible now, currently i have the V10F but all i have is download mode

I used this method for my P930: http://xdaforums.com/showthread.php?t=1784709
[LG Nitro HD] bobo122:
i followed everything but in the final step i mistakenly ruined everything. i was copying the commands and pasting them in the cmd, and removing the space that comes after the command line. i didn't pay attention that the last command line didn't contain a space at the end, so the result was that i did the following:

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/mmcblk0p2

dd if=/sdcard/system.img of=/dev/block/mmcblk0p27

the end result is a hard brick, i guess :/ .. is there any chance to revive it ?

it will not turn on or enter download mode or charge.. when i connect it to the computer i get qhsusb_dload
[LG Nitro HD] Swetnes:
Ouch...you are not alone I did the same thing at the beginning of January including writing the system to block 2 instead of 27. The end result, I did a warranty exchange through AT&T. Short of that there are places on the internet that can fix this or you can order something called a "J Tag" box, I think, essentially doing a factory reprogram. Good luck.
[LG Nitro HD] andriusic:
So right now Im on v20c , and I cant downgrade, my phone restarts at 4% when I try to flash v10f. can you explain what you did to get gingerbread!?
[LG Nitro HD] nikolayds:
Did you rename kdz to 'V10F_00.kdz'

and you must let Korea for a country when ask by 'UpTestEX_mod2_marwin.exe'

Or you can try this steps:

1. Download P930_UDT_v18f_04112012, self-update

2. Put the phone in Download Mode

3. Run P930_UDT...exe

4. After the update complete you will have the phone in ICS ATT Rom, official

5. Download TPSparkyRoot_ICS

6. Put the Debug on on the phone

7. Run TPSparkyRoot and follow onscreen instructions.

8. You will have a working phone

update stuck @ 4% error

This is something which I experienced yesterday twice, albeit with an lu6200.

Although the updating seems to be stuck @ 4% I think the phone is still getting updated in the background. I left my phone as it is stuck @ 4% for 10 minutes & it automatically booted up to ics.

So maybe if cancelling & repeating the update several times still result with this error, I would suggest you leave the updating alone for about 15 minutes to see whether phone boots into ics.

Help! Unable to root - read-only file system

I've unbricked my phone before and never had this issue. Each time I try to root after, it fails (with every different root script) as its full of errors saying that the file system is read-only.

How do I fix this? I tried accessing the sd card is DOS and attrib -r *.* but Windows doesn't show the files as read-only anyways. I imagine I need to use ADB. Can someone give me some direction please?

Thanks!

Of course, as soon as I post this, I decide to try it ONE MORE TIME and it worked! The one root script that worked was posted by MrUncondensed on pg 37 of this thread. If you're having the same issue as me, download that root.zip and run it. Be sure to follow the directions to the letter as far as turning the wifi off and on and restarting the phone. On the 3rd try, it worked for me.

I decided to give it one more shot after posting this and it worked. Thanks to MrUncondensed! On pg 37 of this thread he's posted a root script that finally beat the read only attributes on my phone.

Towards the end of progression bar, stage of the update, an error occurs.

Hello, I have a curious problem. The whole process starts with no problem. Towards the end of progression bar, stage of the update, an error occurs. A message tells me that there's a problem of communication with the device. It stops around 80% before displaying the message. Yet at the beginning of the operation it tests the connection with my nitro hd and validates that all goes well. He decompression and crashes during this step. What do you do? Help me please. I also notice that there is a small window at the bottom right of my computer telling me to check my internet connection and restart the application after. What to do? However, I am connected to the Internet.

Help please

I remember that I installed the drivers without a problem.

I tried following the instructions in the first post but I get a crash saying "LGUserCSTool LGMobile Application has stopped working". My guess is the B2CAppSetup program is pulling the latest version of the LGUserCSTool that doesn't seem to work with this method. I'm trying this method to downgrade my phone to Gingerbread since ICS has the random reboot issue on my phone. Any one know how to get an old version of the tool? Or am I missing something obvious?

Thanks
[LG Nitro HD] strabo231:
Use the version included in the file I uploaded. There is also a step in the instructions explaining internet port changes to prevent that version from updating or pulling the updated version of the support tool.
[LG Nitro HD] chunter2:
A couple days after I posted I did find that the version in your download did work although the kdz file in your zip was corrupt. I was able to find a good kdz file from lg-phone-firmware.com but I can't seem to root it. I've tried a couple different versions off that site but all the different methods of rooting I've found don't seem to work. I'm just trying to get it back to either a Bell or a Telus version of gingerbread but those versions don't seem to be online. I've got the Bell files but not in a kdz.

I'm trying to get my friends phone debricked, i tried flashing a recovery through the adb/shell and after i rebooted the phone to try and go into recovery it just stayed at a blank screen and the computer shows a device called QHUSB_DLOAD and doesnt find any drivers for it. It doesnt seem to go into download mode either is it completely bricked?
[LG Nitro HD] kloz:
I dont believe the LG flash tool supports kdz. Also the kdz file provided is not even for the p930, but for its brother the optimus. If you have at&t like i do use the post#29 method.

Keep trying. I had the same problem.(if i held the power button to turn the device off it would sound like it was being unplugged/plugged into the pc very rapid.) Take the battery out/in and try again to get into recovery.

I can see that the phone does power off when i hold the power button because the dload thing disappears but if i try to put it into recovery it pops back up, and same for download mode too. I hope its not completely bricked but i seen on the recovery method others have said it hard bricked theirs

[LG Nitro HD] kloz:
The adb shell is nothing more then a type of ssh. If the su command fails Your not rooted and the next shell commands will fail to copy the img files. su=super user=root. run superoneclick and make sure it says its done and it worked

I dont know if its just me but it would not work with the battery out. I would leave it in when your in download mode. Also make sure your directly plugged into the computers usb port. Usb hubs can cause some strange problems esp. When doing low level communication

Are you sure the phone is in download mode with the battery in. Phone shows up as android serial device and no others. Ive seen where other posts mention to disable other usb devices. Port set to port 41. No usb hub inline between phone and pc? Also unplugging and plugging the usb cable when its at the ready state?

Also somewhere else ive seen the mentioning of unplugging all other usb devices when trying lg flash tool.

If all else fails try another computer.

Yes, the batttery is in, I am plugged in, and the screen says "Download Mode"

It does show up as "LGE AndroidNet USB Serial Port (COM41)

Like what?

Yes

Yes

Tried

Which ones? I only had one other thing plugged in, I unplugged and tried again.

This is likely my next step.

How long does it stay at the "Ready" state? It seems to stick there forever.

Also, when in download mode, should ADB see my device? adb devices yields no devices connected when in download.

Also, I set LGFlash to save a log, and this is the XML that it saved

[LG Nitro HD] drumist:
Your phone is not bricked if you have CWM installed.

Turn the phone off, then hold volume down button and power button until it asks if you'd like to "factory hard reset" the phone. Let go, then press power button twice to confirm. (This doesn't actually reset anything, it just loads into CWM.) From here you can reflash the correct ROM.
