Black screen on my optimus black - LG Optimus Black

Hi all,
Please help me out.I brought my phone 1 week back and installed cyanogenmod 7 on it.But after using it I thought its not so good in terms of look.So I decided to revert it back.I downloaded andoird 2.2 firmware from LG website and used KDZ to install it.But when I was installing it phone restarted automatically and LG logo appears and a black screen came.I tried to install many time but still stuck on this.Please help me..I blocked my internet connection and I tried with different modes like emergency and diag and disabled LG modem in device manager.Nothing is working.Please help me and whether I can get it to LG service center and whether they can find it out that I flash my phone.So that I can repair it telling it is in warranty.Please help me guys.This is my first android phone.

Did your button always flashing? What ROM version did you use?

yes the buttons are always flashing after LG logo and when I get the black screen I
am using V10A_00.kdz india version.Please help me

Please don't be panic, it also happening to me few times ago...
Did you already got this tutorial?
Find another version of ROM, try V11B.

Thanks a lot!!! I will try to install and I will let you know whether its working or not.

Okay, do your best..
I'll be online for the next 2 or 3 hours...

Its working now..Thanks a lot.I will never forget your help..

But the problem is now I am not able to connect to 3G gprs.Any suggestion please..

Now I am getting gprs.Installed some old firmware.. thanks a lot again..

Thanks

Hello, this exact same thing happened to me, don't worry, your phone isn't dead.
First you might wanna recover your phone so you can calm down a little by knowing that your phone is alright. To do that you have to look at the LG logo that appear when trying to turn on the phone, if it's white with white letters, you are on Gingerbread partition, if it's Red (kinda of pink) with white letters, then you have the ICS partition.
As soon as you see that, you have to download from this link: http://forum.xda-developers.com/showthread.php?t=1969797 a toolkit that will recover your phone so you can use it again. If you saw a white LG logo, then download the Gingerbread version of the toolkit, if you saw a red logo, then download the ICS version of the toolkit. To recover your phone just follow the instructions in that post and in the program.
After that, you can relax a little by know that your phone is ok. Know you might want to try using Smartflash to upgrade your phone to ICS.
I also had problems, when using Smartflash do update the files 1 by 1, mine stopped halfway through.
Still having wifi problems though

[Q] P970 isn't starting

dear experts,
recently i've rooted my lg optimus black, installed clockworkmod and instaled a custom ROM, this one was too buggy, so i decided to install another one, while it was installing, the connection was lost, and my phone now only has half of the software installed and doesn't turn on.
it is not showing any signs of life, no bootlogo, no less-black background, and i can't get it in s/w mode.
used smartflash.
i hope someone can help getting a ROM on it.

Oh. I understand your situation. Go over to the nearest LG Service centre and inform about your phone not working. Explain to them that you were using LG's software update tool to update your phone. From there, they will fix your phone.

I have the same problem..I upgraded my phone to the official ICS by LG..then I rooted my device and install ROM Manager..
then use flash clockwork recovery..after I reboot into recovery..and now when i want to power on my device it flash Security Error...I cant open it...can someone help me??
Ics doesn't support cwm. U should install an older version of gb and then install one of the roms from the development section wich support cwm if u want it. To install an older version u can enter in sw mode by pushing and holding volume+ and connecting ob to the use while it's turned off. I u don't know something u can ask me, had the same problem and solved it

[Q] 6 Hours later = Brick... Official LG ICS [SOLVED]

Hey everyone.
I have the LG Thrill (P925) from AT&T. I'm used to changing roms and trying new things.
Well today I get a text from AT&T saying ICS is out, so I go and download the LG Mobile Support Tool
like the text says. The first few times don't work. I got stuck at the LG boot logo. (I didn't wipe the phone before.)
So I wait an hour to 1.5 hours. Still nothing. I try again and search the forums while I wait. Someone says to try using XP.
So I try in XP mode under Win 7. Everything is going well up until 90%. It does the whole driver disconnected sound as per normal
but then it happens. My phone starts up and shows the LG logo for 3/4ths of a second and then restarts (Black screen for 2 seconds) and
then repeats the whole process over again. What can I do?
(EDIT: Almost forgot: I was on CM7 when I tried to go to Official ICS)
All from the official LG tool...
SOLVED
After trying a few things I held the Volume up button and the power button to get it recognized by the computer. Then
I found a different copy of the LG Mobile support tool than what was on their site. I used the recovery phone option and it worked!
Hopefully this will help someone. I'll post where I got the tool soon.
Could you please give a link or tell me where you got the other lg mobile support tool. Because everything was going good for me and my phone restarted after it was done updating. But when it restarted it got hung up at the att animation and it just stays there... The way I got the official lg mobile support tool to recognize my phone was to put it into download mode also.
I got the KDZ_Flashing_Software.zip from this post: http://forum.xda-developers.com/showthread.php?t=2191698
Install the msxml from the zip then you can use the B2CAppSetup program.
Hope it helps.

Did these suggestions work for you? I'm in the same spot (frozen at&t logo). I've tried recovery phone several times to no avail. Trying one last time hoping for a miracle.
I was running a acidhazardrom gingerbread rom before attempting to update to latest official ICS. Any other suggestions would be appreciated.

I found out what I did wrong. I didn't uninstall the version of the LG Support Tool before using the one specified in your first post. I removed the original LG support tool and used the one you found and it worked.
Thanks for your help.

I know it's something I did, probably the custom image I had running, but the LG Support Tool totally borked my phone. My Thrill would only stay on for a split second, and would continuously boot cycle when plugged into USB. The boot cycle was so fast that half the time it wouldn't even get to the LG logo!
Fixed it with fastboot (omap4boot) and SmartFlash Tool. What a nightmare. Only good thing is I was able to flash from BIN file directly to ICS.

Thanks for your help too. Obviously these issues stem from the fact that we used custom roms on the Thrill. It doesn't help that the LG Tools are complete software crap.

I had this problem like 5 months ago
OK read this and follow the exact guide im doing it personally so that you dont have to search! kk
(for getting your phone working)
1.install the phone drivers from the website ( it might show on the com port thingy then )
2. flash only a gingerbread rom or froyo rom because the ICS rom is locked with a bootloader and will cause the lg logo thing all over again if you flash
3.From this link download the gingerbread rom( download the V20A from venezuela )( http://lg-phone-firmware.com/index.php?id_mod=1 )then use the rom convertor ( go to this link for the guide on how to flash http://forum.xda-developers.com/showthread.php?t=2144577 )
4. if it works, all you have to do is put a rom on your sd and go on with your life
( PS I suggest you try HUEXXX's IZS ROM or Marvel V9 as they both are really stable and works really well)
as for other roms
Dont forget to click the thank button on the corner of this post

possible but not safe!
causes permanent brick if not done well ( i think )
your not detecting problems could be anything!
try reinstalling the drivers all over again
or try another computer!
and also the USB CABLE you are using should be lg ones
and if any lg ones dont work use your OB CABLE!!
REPLY ASAP WITH RESULTS

Tried reinstalling drivers about 20 times;
Tried on another computer still the same;
Tried other (not LG) cable still the same
Today I was at local service center, they said that they cant fix it, so they sent my phone to a better service and they have some kind of box mobile phone fixing tool. Looking forward, that costs 10 to 15 euros. hopefully they fix it.
