Bricked lg ob pls help!

im a new owner of LG Optimus Black. i updated it via LG Mobile support it was smooth. then i tried updating it to v20O coz mine got v20f. when i flash it using smart flash tool, in the middle of the update i got an error message, i tried it so many time. 10x i guess until it turns off and nothing happens. when i put the USB cable still nothing happens. black screen, no light. literally its OFF. also the S/W mode is unable to access. unlike before i flash the v20O update. what should i do to make my OB back in life again? any help? i'll be more thank you if you could help me. thanks in advance! more power!

If you cant acces s/w mode.
Service center it is

try again to get into the mode S / W upgrade and remove the battery still hold the Volume + button while connected via USB cable to your PC if LG OB mod S / W upgrade not , then only repair service: (

I had the same problem. I reinstaled lg drivers, than enter in s/w mode and connect but by other usb. After that reflash by smartflash using stock rom. Should be ok. I think. After that you can root the rom and instal cwm for flash by zip files with other roms. Ofcourse if you can enter in s/w mode. If yes, you can fix yours problem.

Try plug in other USB
Reinstall lg USB drivers
restart the system
when processing, don't move the cable or don't allow loose connection of USB cable.
Finally, this is the way, If it fails, go to service center

Install software updater tool from LG web site.
Before it take back up memory card to PC
Delete lg driver and install again
Restart PC
Remove battery of your mobile and refit it but not try to switch on.
(Veryfy that battery full charge at least 60 percent.)
Start LG updater tool it is called ( b2c app ) on your PC
Now
Keep one end of cable to LG mobile and keeping pressed the volume up key insert the another end to PC. The phone must show software Update mod on screen. Or some problem in driver or something
But one thing required is broad band internet necessary.
The b2c will detect your mobile.
There is an option for recovery phone
select it and it will ask inside and serial number
Only individual Number you can input and Press check
Wait wait wait
Some warning message appear
Click yes.
Wait the PC to download necessary files from net
And it will flash the software to mobile
Wait to complete the process
And its all
It should work
Best of luck
Pl ask if any doubt.

achieve APX mode and other tricks adhoc

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.
Regards

Update failed - black screen!

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)

Out of ideas... you can try to use the official lgmobile tool and use the emergency mode to recover it...

No. That just leads me to the LG Mobile Support tool, and it can't do anything.

Did you try to get SW upgrade with battery in? (I had the same problem)

Yes.
I have tried both with the battry in the phone and taken it out

Hmm, did you also pulled out the battery while using apx mode(nvflash)?, Also look in device manager or a new device comes up if so then do install drivers or something like then and then click for search automatic. It will probably install because I assume that you've installed the APX drivers before already with the toolkit. I could and have unbricked my device from even worse bricks then what you are having now so it should be possible to fix yours also. You know, the 2X is really unbrickable with NVFlash.
