Lgp990 stuck at logo screen, not detected by windows

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.

[Q] Optimus 4X HD full brick

I tried to put the CM10 on my phone, after installing the zip in recovery mode, I rebooted the device and it never returned to start. Does not show a single light. Do not enter in any way with any combination. When I connect by usb the only thing that appears in device manager is "apx device." Already tried so many things and nothing worked.
anyone have any idea what's going on?
by the way, I tried a lot here in xda before opening a thread.

is your bl unlocked?

No, no, no and no. the only sign of life when it is connected to the pc. Appears "apx" in device manager.

Yeah you are in apx mode, which is basically the boot section of the nvidia tegra chipset.
You should be able to boot normally by unplugging the phone, remove battery for a few seconds, reinsert and hold power button for about 10 seconds
Also try holding power and vol+ (hold them a while) you should be able to boot into normal recovery

I've try that but dont work.

In device manager the apx device is it properly installed or does it have the triangle?
When it first connected as apx device it probably asked you for drivers, i doubt you installed them.
I don't know if the apx drivers for the 04 are out already, check these terms in xda i know some people have been working on them.
Maybe you can find them here
If the device isn't bricked you are in a situation in which you should be able to flash stuff.
For some this method worked:
Try turn off phone
take battery out
hold vol- and put usb cable into phone
if s/w mode starts put battery in and flash kdz
Otherwise check this thread out
or this
I have to go out and can't follow you for a while, sorry

The only way for you to get connected in APX is without battery, connect to PC while pressing vol- & vol+.
Anyway... why you want to do that? APX mode doesn't work in JB.
Ok... I got it.
Did you tried to deactivate the APX device in device manager?
You can try to performe the bootloader unlock again (run adb and connect the phone while the program wait for device...)
http://www.4shared.com/rar/HFf4newq/LGO4X-UNLOCK-BOOTLOADER.html (instructions inside).
Or try to get in SW mode by trying untill it works... (connect to PC while pressed vol-).

Any update on the problem?

No, i think what happened was that all the firmware is erased and this naturally gave access to apx that should be hidden by the software. Probably there was some error when I wipe to put the CM10. I see no other explanation.

The phone is actually mine. Already sent it to warranty hoping they'll fix it.
Resuming, the phone went unexpectadly in APX mode and havent found a way of quitting that mode, couldn't boot S/W neither bootloader.
And btw the phone is carrier locked and to be honest I'm not sure if it might be part of the problem or not. Anyway in about two weeks the phone should be back and hopefully fixed. If not I'll check here for some more help guys, thanks for attetion so far

[HELP] Boot loop and Cannot enter recovery/fastboot/flashmode

Guys,
I flashed a stock kernel (.207) through fastboot for relocking bootloader.. I was on CM 10.2 (FXP)
I was planning to flash .207 stock through flashmode after relocking BL
But the phone continuosly bootloops. It does not stay in fastboot or flashmode for more than 2 secs, so I cant flash the original kernel of CM 10.2
Also, pc says USB device not recognized when I connect in fastboot or flashmode,I have installed all the drivers also.
Please help me out guys, its urgent..
SOLVED:
Tried this method:
"You mean the problem you were facing is, it keeps on bootlooping even you turn it off via yellow button(off button at the back).then you need to do this. First, ready the flash tool ( until it it prompts to connect the phone.) Then open the back cover, you need a stick or a ballpen to be a tool for pressing the button, then put the pen in standing posistion(the tip's up) hold your phone,place the yellow button against the tip of the pen, press the volume down(if im not mistaken for the flashmode). If you follow me right, you will notice that if you push your phone down, the tip of the pen will trigger the button.. Then ready your usb data cable using your other hand but dont insert it in this point... Now press your phone down until it turn off. Hold and press the volume down(dont release it until you see the green light. Count to five so the movements will sync, after 5 release the pen and immediately attach the cable. If your lucky enough, you can do this in first try."
IT WORKED!!! LIFE SAVER! thanks to Aljon!!

Uhm to relock the bootloader you need to install a Stock ROM via Flashtool.. No need to mess with fastboot mode etc etc..
You could try to reflash the boot.img from the FXP you used before.

[Q] Z1 won't turn on

Well i've got this problem with a Xperia Z1 from a friend of mine. It's not powering on. If i press the power button the phone won't turn on. It can enter fastboot but that is everything. The phone is fully charged because that's the only thing that works so far beside the fastboot. It's on stock firmware no custom ROM. Maybe that you people of XDA have the solution i hope so or experienced the same problem and that it is fixable.
Greetings,
Kyrindia

I Had a similar issue, my volume up button got stuck, causing it to always boot in fastboot.
Power up phone, connect to pc, install driver, then run fastboot on your pc and run:
Code:
fastboot continue
Let me know if it helps!

Did something happen to the phone?
Like dropped it in some liquid other than water?
Does the camera button still function?
For an android reinstall:
Boot the phone normally and perform a software reinstall using Sony PC Companion, connect it via USB to your pc.
With PCC you can fully reinstall the software on the phone.

I can get to it via recovery on my Note 9,I have no explanation as to why you're having issues.
Perhaps try the method given in post #2 of this thread.

New method now for Note 9 download mode. Power off, hold Bixby+Vol Down and connect USB cable to PC to trigger it.

Can't boot into download mode too....
