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.

I tried to update my LG P880 with LGMobile support tool yesterday.
After connecting the phone, I clicked on Start updating. A window popped up, telling me that it was downloading.
When it came to the update part, it lost connection with the phone. I did exactly as it said I should do (unplug, take out battery and put in in again, turn on the phone and connect it to the pc), and it restarted with the updating.
On about the same point as last time, the pc lost the connection with the phone. I did the same as last time, but now, the phone just doesn't boots into the S/W update screen.
The phone is NOT booting, NOT working to flash kdz, and it is NOT detectet as a phone, neither by the pc nor the LGMobile support tool, but my pc detects a device called APX when I connect the phone to the pc.
What can I do? And what is wrong?

LGMobile support tool needs the phone to be in normal mode (generaly...).
No SW or other, just turn ON your phone and connect it to PC.

Take out the battery, wait 30 sec. and put it back, press vol- and connect to PC while pressing.
Nothing is working
I don't get the SW upgrade screen when connecting to PC, the phone is an "Unknown device" og named APX under device manager, and the KDZ program cannot find the device.
Is it any other tings I can try?
so if its apx, you can simple flash it via APX mode with nvflash, right ?
(i remember when i rooting my Optimus 2X via APX , that flashed prerooted system.img... so you can try this method)

Well My sister and her boyfriend were trying something whit her phone, I dont have a clue what the hell they were trying, at the end of the day, she comes to me with her LG P970H with the screen S/W Upgrade please wait while upgrading.
I try to Connect the Phone to the PC with the battery and The Pc makes a Sound and says that the USB is not recognized.
I connect the Phone without Battery And the same happens, Sound and not recognized.
Connect Pressing the Vol - , Same happens
Connect Pressing the Vol + Same Happens
Connect Pressing the both buttons with and without the battery Same Happens.
Allright then its the drivers, I go Ahead and download the Lasted Usb Drivers from LG, Try again and nothing new happen.
Download some Old Usb Drivers, Same thing nothing new happens.
Why and When does the S/W upgrade Please wait while upgrading screen appears. I think I can install another OS or make a Hard reset on the Phone if i can get the PC to Detect it. Its not the Cable and its not the PC. Tried 3 diferent cables and 2 pcs and a Macbookpro. I live in mexico and im phone company its TELCEL if that helps.
It appears as soon as i turn on the phone.
PD: please if you know what im dealing with , write the answer for dumb people like me, its hard to know what you are talking about when using names like ST, KDZ and stuff and english its not my mother languaje so dumb it for me. THX!
You must read this.
And you need the bin and fls from KDZ to extract and root your device(if you want it rooted). Since here you should look for yourself.
A soft reset is keep pushing Vol+ + Power for 5 secs.

I think the phone was rooted i really dont know i think they were trying to update the system. I tried the Soft Reset Nothing happens, I think its not charging anymore it will only turn on when i connect the Usb cable. I tried removing the battery for 10 mins and tried again all steps. My Problem its that the pc Detects that theres an Usb, but it wont recognize it.
After i plug in the usb cable to the phone and i disconect it, it will remain with S/W upgrade screen for a few seconds before turning itself off. I cant turn it on by the power button.

And if you connect it to the PC normally?
Does your device manager show nothing at all, or does it maybe show unknown devices and you only have to install the drivers manually?

I had similar Problem when using a 64bit-os. if so, try to reboot with disabled check for Driver-signature.
Just press F8 during bootup. if you get a promt fo selecting boot-device, press enter and quickly hit F8 again.
when System is booted remove the Batterie, press and hold vol+ and connect to usb (Batterie is still removed)
now my OB was detected with S/W Upgrade Mode

It says Usb Device Not Recognized, Unknown Device, One of the Usb Devices has Malfunctioned and Windows Does not Recognize it.
I have tried to Install Usb Drivers and everything and The pc Still Recognize the Phone. The SFT has no comunication Device because the pc its not recognizing the usb so i cant do ****. xD

Nope, Didnt work i even uninstalled the Drivers and Reinstalled both old and new usb drivers for the phone and rebooted each time to see if it worked. Same problem. Dont know if this is important but the S/W update screen appears without pressing the Vol+ or Vol - or both.

Are You sure you disabled Driver Signature Enforcement.
this must be done every reboot you do or your phone will not be recognized in S/W Upgrade Mode. After flashing with SFT it is not needed. Only for flashing in S/W Upgrade Mode.
The currently available drivers work fine with x64...
I never used SFT on x86, and I never had a problem. I didn't even need to disable driver's signature enforcement, ever.
What's weird here is that his phone boots in to S/W upgrade mode without any key press. It seems to me that now you got there a flashlight...lol

Have you tried the hard reset button?
Under the flap next to where the sim goes, is a tiny hole. You need a pin to press and reset.
Edit: Do you have ADB installed? Have you installed the Sony drivers. on your PC?
You also need to run the exe in the Drivers folder within Flashtool, to make sure you have correct flashomde drivers available. Installing these drivers is very difficult in Windows 10 and it require restarting the machine in safe mode, and going into the advanced settings to disable driver signature checking, this how to video is for windows 8, but you'll get the idea
All of those need to be in place before flashtool will work.
Does it go into flashmode? Make sure it's turned off, start flashtool on your pc, then hold the volume down while plugging in the usb cable. If flashtool recognises it then you can follow bilboa1's great guide. You will probably have to start from scratch, old firmware, root exploit, recovery etc etc.

Exactly the same happened to me this morning. I had not time so I left it and came back at midday. After trying to reset it many times it finally turned on (maybe 15 min trying), but the USB port completely died... Then I notices son humidity in the two cameras crystals. The phone was working great, I even play asphalt 8 for 20 min and nothing wrong happened. I've just sent it to repair. Tech guy told my that maybe the motherboard is compromised.
The only thing I can surely tell you is keep trying, it worked for me.
