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.

run through the MY Android Solutions link below, have listed all your options therein

thanks but it doesn't work for me, i think it's a usb connector pin problem or something, but i'm afraid of buying one and brake the phone soldering the connector.... any other option to check if the connector is broken?
thanks.

Do you can go to the download mode? Try with odin on PC.

I understand but sometimes you can't connect whit PC but whit Odin its doing. (Sometimes)
Start Odin with Windows and try it.
Very important - your phone must bee on the DOWNLOAD MODE. If its not doing your USB Connector on the phone its defect.
I have same problem having 6 months ago.

Are your drivers installed? Install those, connect the phone so the pc to recognize the phone and begin install of drivers for it. When you plug in the cable be sure to be in download mode, you need the mtp driver to be installed. Remove the fone when it finishes.
After you install the drivers open odin add the files and only after plugin the phone in download mode. It should be ok then.

It's not driver problem. I've flashed with odin and heimdall a lotof times. The phone failed to recognized time ago but when rebooting aleays solved thw problem, not this time.i get error code 43. If i force driver install i get error code 10 in device manager

Try to remove the drivers first. After that close the pc, remove the power cord and hit the on button. It will discharhe any charge left in your sistem (it will reset your usbs). Plugin the cord, open the pc normaly and then reinstall the drivers.
Put the phone in dld mode and see what happens.
Hope u resolve ur problem this way.

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] Flashing new bootloader - help

Hi,
I am currently on the old GB bootloader and want to flash the new one but for some reason my usb to pc connection never seems to work. I had this problem since cm7.1 rom. I am currently on the Avatar rom and somehow when i plugged my phone to charge on my laptop, the connection worked and it prompted me to turn on the usb storage.. but it again stopped working. I would really appreciate some help with this, is there any way to completely go back to the stock rom (I dont have any stock rom backup) just by flashing a zip through cwm. or even better to update to the new bootloader from the phone itself.
Thank you in advance

Use the AIO Toolkit by spyrosk to change to new bootloader:thumbup:

Thats exactly what i tried but my laptop doesn't recognize the the connection. I have all the correct drivers installed.

You install the Nvidia USB driver ? to use de AIO toolkit with nvflash is than better , but you must run your phone in APX mode (connect to PC , remove the battery, pres vol - and + , ) YOU MUST INSTALL THE NVIDIA USB DRIVER , after that run AIO toolkit and press option 8 , i think
and That`s it

[Q] LG P970H S/W Screen

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

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
