Hey guys,
my Optimus 2x running the newest CM10 Paranoid Android ROM decided to enter a reboot loop today.
There honestly was nothing I did that could've been a cause for that, so it's rather confusing.
Anyway, removing the SD card and/or the SIM card didn't yield any results, power has since been plugged and unplugged, just as the battery, but nothing helped either.
When I try to use the AIO-Toolkit with the nvflash drivers installed, plugging the phone without the battery in as described there gives me a Windows Explorer popup saying that the device could not be recognized and that there is something wrong with the device.
There is a recovery installed on this device, however I only used it with the "Reboot to recovery"-option from Android yet, and both starting the phone with the lower volume button and the upper volume button pressed did not yield to a recovery boot.
Are there any options left I could try?
EDIT: I was able to get into the Team Win Recovery Project recovery and - using another cable - I was also able to use nvflash. I'll proceed with nvflash soon and wait for the results.

I've had the nvflash driver installed all along, but it didn't work.
In the end, I solved it by using another USB cable.
Somehow, the one that came with my P990 would let me charge it via USB, but wouldn't allow it to be recognized...

Hi there, I'm new here but I have been following this forum for a long time.
Here's my problem:
I own a LGP990 with DJANGO rom. apart from the random stuck in the DJANGO loading screen which required me to reinstall it, it was all working fine.
Until yesterday, when I plugged it to recharge. The battery charged for a while and then got stuck for hours when almost done.
I unplugged it and try to turn it on but since that moment it always gets stuck at LG logo screen and when plugged it doesn't display any battery charging. I then tried to start recovery to reinstall from zip as I did every time it got stuck in the django loading screen, but recovery does not start.
No problem, I thought, lets smartflash/nvflash a stock rom and i'm good to go. Wrong, the phone won't even get recognized by windows, though I installed the driver several times (disabling driver signature as well) and running it as admin; i tried different driver versions, different usb cables... It does not even play that background sound when plugging usb devices...
I'm using windows 7 32bit.
That's it, I have ran out of ideas... anyone got one? (besides sending it to assistance, since warranty is voided)
little edit: whenever i plug the battery the phone start by itself!

I meant to enter recovery. If your phone turns on when you put in the battery, the power button is stuck in a connected position so to enter recovery remove the battery, press the vol- and then insert the battery. If you get your phone to enter recovery and reflash the rom I will tell you what to try to fix the issue.
1.)remove battery
2.)press volume - and volume +
3.)connect phone to pc via usb
4.)download apx driver
5.)(go to device manager install manually apx driver, select the folder where you downloaded and extracted apx ini driver file
6.)flash using nvflash
7.)enjoy.

in AIO you have an option to smartflash roms not nvflash. You need to unpack a KDZ rom and install the ROM via smartflash
all the instructions are in the op of the AIO toolkit
the problem still remains, no phone detected and no com port appears in smartflash...

mmmmhhhhh..... change usb port, change cable, reinstall the drivers. other than that I am at loss
AIO tool has an option to install Nvflash driver. Its the last option in a different color.
Or you could try to reinstall LG driver. I just downloaded the latest driver from lg support tool today. It works fine.
And be noted that you have to hold down both volume up and down while plugging the USB cable to enter nvflash mode. Holding vol down while plugging the cable in will enter boot loader mode which is not the same thing. Remember to remove the battery first of all.

hey...ur problem solved??
Hi there so I today truied to update to Eagles Blood custom Rom using Rom Manager to flash the new rom onto my O2x. The rom supposedly installed correctly but then when it booted it just gets to the unlock screen you unlock it then it reboots after a couple of seconds.
I can't get into recovery mode by the usual power on volume down technique as this just results in the phone continuing to load. I have tried different combos of power button reboots with volume button up, volume down and both together none work the only difference is that one of those results in just the LG logo rebooting.
I read a few posts about using nvflash or even the lg recovery tool using imei number etc but still no dice basically when I do the connect to the pc with both volume buttons pressed and the battery out it connects but doesn't recognise the device. I try the device manager and updating or removing the driver but regardless of how and what I try it either tells me it's using the most current driver or that no driver is actually installed.
This the same when using NV Flash i can't apx drivers installed and the device if I try to skip that step and go straight to the flash.bat command i just get usb device not found or connected or something like that.
Please help i am willing to try anyrhing and i really don't have the money for a new phone. I only have to get it working long enough or far enough so i can reinstall my backup i did before attempting the rom install this morning.
try connecting to different usb port(I suggest the backport of your PC)
and if that didn't work, must be a faulty cable.

Unfortunately the cable is fine as if I'm not holding the power or volume keys I'm charging the batteries. I'm thinking there's something wrong with windows and the way it detects it possibly as i've trawled a fair amount of forums and tried a lot of what others have managed to get working with exception to someone else who had the same problem but couldn't get a resolution (that he posted about).
May be your USB port was broken.
Have you actually installed the apx drivers required for nvflash to work?

you're not on Hard Brick, right?
can you try Smartflashing?
you need to install LG united drivers first.
APX won't install
So the problem is that my PC will pick up the unknown device. But it will not allow the install of the drivers. I can install the LG universal driver. The phone will connect as a unknown device only with error code 43 (device has been stopped) you try installing the APX drivers and the install of those drivers fail with error code 10 (can't start the device) this happens on both my stuffed phone and the brand new replacement so I am at a loss I have tried this on Windows 7 pc and also a Win 7 laptop (64 bit and 32 bit respectively).
The whole affair is frustrating as hell as I an't get my new O2x recognised either I can't root that to put my nandroid backup on and I am stuck on Froyo that I can't seem to root at all or even use lg update tool to update it to the latest stock firmware.
WHat about rooting apps
So with the obvious ways not working are there any actual apps I can install on my phone that will root it that way I am certain this is how I did it on my first O2x just can't remember what the name of the app was. So if anyone has apps or links to apps that may do this and or do do this please post back.
Have you actually tried a different USB cable? I notice you said the cable charges the phone, but this doesn't mean that other cores/pins other than the ones used for charging aren't damaged.

different windows and different drivers
My suggestion would be try it on some other computer and different drivers. Or on same computer but reinstall Windows and ofc different drivers.
I'm suggesting this because I had experienced some what similar things on LG phones.
Hey there,
Just today I decided to download a new ROM for my LG Optimus 2x. I tried to install the ParanoidAndroid CM10 ROM via the CWM Recovery. (place files on SD card, reboot in recovery, wipe, install) But I accidentaly installed the version for the new bootloader instead of the old bootloader which I still have. So needless to say, that didn't work and I was stuck with a boot loop, the phone didn't get passed the LG animation screen. So I figured out that I needed the older bootloader version. I downloaded it, put it on my SD and tried to boot into CWM Recovery... nothing. It did not catch the Power + Volume-down combination and instead just continues its regular boot-loop with the LG animation.
I had flashed a ROM with nvflash before, so I installed the drivers (I tried this step on 2 PC's mind you) and put the phone in the desired state (battery out, usb cable connected, press volume-up and volume-down for a short while). But to my surprise, my computer did not recognise the phone. It doesn't even see it connected or anything! I did install the LG Mobile drivers beforehand, if that makes any difference, but nothing changed the situation, I couldn't get my PC to recognise my phone in NVFlash mode.
Okay. I'm a though guy so I figured I could still try and use the Smartflash method. So I install the drivers necessary, hook my phone up with the battery removed, hold the volume down-key and I see the "Upgrading software" screen, good! But again my computer did not recognise my phone just a little bit. It doesn't show up in the device manager and neither do I have an option to install additional drivers.
I'm baffled by all this since I did not think one ****-up would brick(?) my phone this bad. Is there any way that I could just get it working again? For now I really don't care what ROM version I have to install, I just want it functional again
Thanks!

LG O2X is 99.99999999% is un brickable.....have you tried the AIOT kit by Sprosk or the Nvflash stuff by Progmaq....
In addition tho this: partitions changed normally with nvflash method.....is it done through CWM?

I did. I tried both the nvflash stuff and the smartflash method. But somehow my computer does not recognise the device while it's plugged in. It doesn't even see that something is plugged in.
I'm sorry but I'm not sure what you mean with the partitions changing through CWM. Could you please elaborate on that?

the old and new bootloader are different in partition layout and the size of partitions....this can be done through only the nvflash method, or kdz method.
look at the AIOT tool kit thread opening post for more information.....
The ROMs which are based on the old boot loaders are not compatible with the new bootloader.....vice versa
-have you tried to change your USB cable?
-tried changing the USB ports?
-using win8, then you need to do it differently.....so check that too
-try using ports directly connected to motherboard....not through any USB hubs
Hope this helps you

Make sure you are pressing and holding both volume keys while you are plugging the USB cable in. Pressing them after plugging the cable in will not put the phone into APX mode.

I have a Verizon LG G2 VS980. The phone was rooted and running stock firmware.
I hit the "Update software" by mistake on a business trip and when the screen went black, I powered off the device in hopes of preventing the update (which I see now was a HUGE mistake.) Now, the phone only boots into fastboot mode. When I try to hold the vol + and power, it takes me straight into fastboot as well as the vol - and power.
I have tried to do the factory reset by holding vol - and power and then pressing it again when the LG splash screen shows. When I select to hard reset the phone, it goes into fastboot mode.
Now, when I plug the device into the computer, the computer will not recognize it. I am using the manufacturer's data cable, I have tried multiple USB ports, I have uninstalled and reinstalled the drivers countless times. Neither fastboot or ADB in command prompt recognize the device. However, the device does show that there is an android device plugged into the computer.
I have spent hours looking through every thread that addresses issues similar to this but I have not found a solution yet. What can I do from here?
First of all this belongs in Q&A not development.
Are you doing the hard key combo correctly? Power the phone down, when when it reboots is vibrates. When it vibrates you hold power and volume down. At the splash screen, you release it then hold them again.
Did you try this thread?

Your computer should recognize it since you had it recognize it before.
Yes, I have tried multiple usb cables and have tried to get into download mode both plugged into the pc and unplugged.
Am I correct in assuming that step one needs to be to find out how to get the computer to recognize the device?

Weird how your phone makes you get a blue screen of death.
Can you say what it writes in blue screen? And also try your luck on another PC.My sister's laptop could not recognize my phone no matter what I did.
Blue screen is most likely due to some broken software/hardware on your PC rather than a problem with your phone itself.So do try it on another PC.
Can you also say, how it doesn't go into recovery mode? When you hold vol - plus power, does it make the phone reboot, vibrating but still stuck on LG screen or does it not even vibrate?

try this 2 fix your pc:
start CMD with administrator privilege -->
chkdsk /f /r -->press enter --> Y
restart the computer, if you lucky it will fix you pc and you will be able 2 fix your phone
(the fix/test take 1-2 hours, depending on how big your HD and if you have errors/bads ectors)
if you r not lucky, you probably have driver collision and it more tricky 2 explain how 2 fix.
anyway, if you in a hurry do it in another computer

its very strange that u got blue screens in both computers.....
the error code that u gave usually points that something wrong with mscorsvw.exe and/or NET framework.
i would recommend to update to the latest NET framework or even uninstall it and install it again.
Another good idea is 2 install the Android SDK (it installs a universal usb driver), this might help - ill try this before reinstalling NET frame.
i hope it helps...
