So i want my original rom back and i want to use the SmartFLash method .
i did everything but when i plug the phone the com port is not filled ... what can i do ?
i tried to do the operation from another pc with APX driver but it was the same
any solutions?
CHEERS
did you hold the volume down button while plugging the usb cable into the mobile phone? did the pc report any usb device plugged in and what was going on with the mobiles display, did it show s/w updating or just the logo?

i hold vol down , the pc didn't report any usb device but the s/w updating it was showing on my display ... when the phone was plugged I entered in device manager and i saw something like : Others devices : Unknown device ...
did you install the apx drivers?
when i hold vol down and i plug usb the APX didn't appear. when i hold vol down + up and plug usb the apx driver appears and i installed it but let me say something
my current version is P999 and in SmartFlash it is saying : version p990
is this a problem ?
the problem is you cant install stuff from a p999 on a p990, tho the phone itself is the same, the partitions are different, if you succeeed in flashing your phone never try that again, at least thru nvflash, as soon as you get your phone going my advice is never flash anything if it isnt with cwm...
as for flashing it, as i told you the same thing happened to me, and i had to flash it from another pc, it wasnt easy tho because i had to insist lots and lots of times auntil i finaly succeeded because the phone wasnt recognised and or failed to flash most times
Since this model is new, i assume all facts are new too.
- SAFE mode is started by holding Vol+ and power button at the same time at startup.(adb shell is enabled, nothing is running(single user mode?)
- FIRMWARE upgrade mode seems to be Vol- with USB cable connected at power-on.
- APX mode is started by holding Vol+ and Vol- down at the same time at power up(when pressing power).
* since we do not have a bootloader.bin yet, it will be hard to try anything. can we use htc onex bootloader.bin?
* tegra3 is also locked with a SBK, which we do not have either (i believe).
-Battery mode
Turn off mobile. attach USB cable to pc and mobile. turn on mobile.
- adb reports shell not found and some root details?
im still digging into the fastboot mode, so information can be extracted on the rom rel. etc.. maybe someone already knows?
ill keep this updated, if i find out more.
APX drivers
Do you have APX drivers for 4X ?
not yet, i assume those for asus prime should work as well?
it not work.
@Dexter_nlb
I read that Asus will release NVFlash for Asus Prime.
Do you think it will also work for us?
I believe they for a fully working apx mode since prime got a full recovery using apx mode?
recovery details added.
thanks to 911rsr

Nothing happens. Nothing shows on screen. When i hook it to computer, it makes a noise that it found some device, and in device manager shows as APX, instead of as modem or anything else....
Bricked. APX mode only
Did you find how to fix it?. I have the same issue after a failed upgrade using LG mobile support tool.
No SW upgrade mode, no screen or leds activity, no nothing. When is connected to PC, APX device is recognized. I found some drivers and the APX device is displayed now as "NVIDIA USB Boot-recovery driver for mobile devices". I'm stuck there. I was looking into NVflash utility but after the command "nvflash --sync" only get "unknow device found"
Can anybody help me please?.
How can I get into SW recovery mode or something that shows some activity from the phone?.
Thanks and regards

i guess not much can be done. sent mine to the service center and got it back 3 days later fully functional. i guess it's easier to restore for LG since they have all the tools and magic keys.
Hello!
just happened to me.
apx mode you solved anything?
one can solve?
Thank you!

NVflash doesn't work, at least after upgrade to JB.
Before give your devices as bricked, try to enter in S/W without battery a few times and after with battery on.
Sometimes stressing the device have some results.
But the best you can do is take it to service.
Thanks gingerboy92. I follow your advice and my phone is in a LG service center now. Hope they can fix it.
I think that's the only safe way to recover it. Looks like Tegra 3 devices have security keys that are unique for each processor and without them you can't go further.
Amigo ruedaslocas, I tried many times to do what you say, unsuccessfully. Thanks anyway.

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??
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?

When you held power up and volume on reboot, did you have it connected to the PC to see if you had download mode?

-check your device manager and see if your computer recognizes it.
-Try another computer.
-Another USB cable
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?

My 1020 got bricked while flashing through WPInternals.
In the middle of the flashing the USB got disconnected and after that I have blank screen. The power button pressing does make phone vibrate. Also soft reset combination makes vibration. However I am not getting anything on my laptop on USB connection. No connection notification. Nothing on device manager. I tried combinations to get it detected but nothing works.
So the question is, Is there any way I can blindly send force flashing to one of the USB port and make it happen ?
JTAG is the only option ?

Hello,
try this: power off/reset and power on holding vol-up key. You should get a flash-and-cogwheel sign on your display. If so, you cna reflash your (valid) .ffu file using PhoneImageDesigner/Lumia Flash Tools (->google!).
Are you sure your USB cable or port is not broken?
Best whishes,

Okay, I have already tried that, since the USB got disconnected during boot loader flash, it does not display anything on the screen when I start with power button or reset combo. It only vibrates.

I have changed the cable too(USB flex cable of my lumia and USB cable too), It does charge battery, does keep flashing the start button once in a while when the cable is connected. I am sure USB is working fine. But not getting detected in PC.
