I recently bought a LG Optimus Black (LG-P970g is what it says under the battery). The phone came with Android 4.0.4. The battery life was terrible and I wanted to try Cyanogenmod to see if I could get better life (and more features).
I was able to root the phone and install ROM Manager. I went through the Flash ClockworkMod Recovery option and it said I successfully flashed it. I put the ROM on the SD card and had ROM Manager restart into recovery mode. However, instead of booting up I get the LG screen with 'Security Error' on it and then the phone shuts off.
How can I get the phone back up?
Resmartflash. Or try to access recovery via bootloader. Or adb reboot recovery. I think you flashed a gb rom on ics bootloader... which is not working.

I was able to use SmartFlash and a GB rom to get the phone back up and running. Now to see if I can get it up to cyanogenmod.

Hello!
I've got a little/big problem with my phone...
first of all im using this: http://forum.xda-developers.com/showthread.php?t=1748984 instead of cwm.
And yesterday i tried to flash a new ROM. First all went pretty good, but the play store was bugged. So i did a new wipe and flashed again, but ofc it was stuck in the bootanimation, so i plugged out the battery... and now all that comes up is first the LG-logo, then the teamwin logo, then it's stuck showing the temwin logo... So i can't flash a new rom, i cant get into recovery mode and when i try to use smartflash on my pc the S/W upgrade wont appear while pressing vol down + pluggin the usb cable, instead the phone is black, the lg logo appears and then it's black again, and it repeats.
Any help or suggestions would be so nice of you!
never use that recovery method, always use CWM non touch version. i think you should nvflash
Use NVflash, me same one time!
Before using rhe nvflash method, try flashing CMW to your phone again. Go to Rusty's CMW thread in the Development section and download it from there.

I have rooted my lg thrill using ClockworkMod Recovery v5.8.4.3 a while back.I noticed the battery would drain fast.So I wiped the data on the phone thinking that would help I did not make a back up.When the phone booted back up i see the lg logo then it takes me straight into cwm. So I downloaded a rom to put on there.It said the rom installed. But when I reboot again I see the same thing lg logo then cwm.Is there any thing I can do now or is it like a concrete brick?

Hello guys, I am new at this forum but I have been reading this for years, but just now I needed to post something.
I have a LG Optimus Black P970 and it's now Bricked, I will try to explain it.
The samrphone was from my father and he gave it to me already bricked, he was using Stock ROM from VIVO (Brazil) Android 2.2 (Froyo) when It bricked, then I asked for him the smartphone and I tryed to use the SmartFlash to unbrick it and put the CWM Recovery as I used to use. The P970 didn't boot at CWM Recovery automatically as was supposed to, but after few hours pressing Vol - + Home Key and Power Button I was successed. Then I flashed Zeus ROM and everything went fine, the P970 was UNBRICKED!. Ok, I gave it to my sister-in-law and she was using it untill tomorrow... Then she asked me to unclock the network so she could use every SIM Card, for this I had to flash another ROM, I asked the P970 to boot into CWM Recovery (holding power button, reboot>reboot recovery) and now It is stucked on LG logo again. I tryed to flash 5 Stock Firmwares, 10A, 20B, 30A, 30B, etc but none worked. I really need it unbricked. I have been searching tought internet but every tutorial didn't work.
Please some one help me, I can't lose this smartphone. Oh, one more thing, I can boot into S/W Upgrade normally...
Thanks!
So you have tried using the smartflasher?? If so then it should be fully fixed... give it sometime to boot though as when I'd restored mine it took like 5 mins top for it to get into the main menu..

Yes, I did it several times and didn't fix the bootloop.
Is there a way that I can wipe data/factory reset thought a computer? Because maybe It could fix my phone, but I cant boot, it's still stucked. I really need help here
any help?
Hi MuriLOCO, I had bricked my p970 before and flashing via flash tool did the job.
You can try flashing it via S/W upgrade.
Go to LG website and download the updater so you could flash it with S/W update.
Hope that helps.
So I was trying to root my phone today running ics 4.0.4, I used that all in one tool to get RZ recovery onto the phone, while in RZ recovery I did something very stupid. I wiped everything from the phone because this is something you must do before rooting right? Anyway I wiped before moving any of the necessary files onto the phone. So I now have a non rooted phone that will go into recovery mode but when I try to boot it, it becomes stuck on the silver lg boot scroon or fastboot logo. I am at a loss on what to do. Any help is greatly appreciated.
Hello everyone.
Recently i was using in my p880 Cyanogenmon rom based on 4.2.2 version and after getting bored of it i decided to come back to stock Lg rom.
After installing stock lg rom through KDZ installer my phone came in a boot loop. I tried to hard reset it through system recovery but when i select the factory reset
the only thing my phone does, is showing me the Dead Android icon with the red triangle. Is there anything else i can do to "wake it up" from the boot loop?
If you have CWM or TWRP installed boot it power + vol. Down.
Download the stock ROM for your region (flashable zip.) Copy to SD card
Then full wipe data/cache/dalvik/system
And flash ROM you downloaded and copied SD.

Use lg mobile support tool to re-flash stock ROM.After that, enter the recovery and do a factory reset.This as always fixed any problems I experienced.The main issue of bootloop after returning to stock ROM is a problem with data partition usually which can be fixed by doing a factory reset, however I don't know why you got that red triangle and I don't use kdz flashers on this phone as mobile support tool does fine job.
