Hello, So i tryed to flash to CM10 rom for LG E970 and my screen went black after reboot. So then I tried t go back to stock with LGNPST and it would get to the logo and stop. So then (lol) I tried using a teenybin instead and now I can't get download mode to show up and all the screen will do it show a gray battery with a lighting bolt and sometimes when trying to power on or get to download mode it'll act like it's about to do something and shows a black screen with google in grey and an unlocked lock at the bottom of the screen. Help is all lost or can i fix this??

Use the KDZ Updater with the latest firmware version of your phone...
First, download and install the latest lg driver. (your phone must be unplugged when installing)
Second, download the LG E970 kdz.
Third, "google" and install the kdz updater.
Fourth, put your phone in "Download mode" by pressing both volume keys and plug into usb port (wait 2-3 seconds, your computer will load the driver)
Fifth, open the kdz updater and select "3GQCT" in type...and "CS_Emergency" in phone mode. Then browse & select the kdz you've just downloaded...and press the Launch button. It should take about 8-10 minutes to complete...your phone will reboot around param.94 then you can unplugged it and let it boot normally.
Finally, make a "factory reset" to erase all previous data and plug your phone to wall charger to gave him some fresh blood.
Give us some feedback & good luck :good:

Try to get in donwload mode pushing together volume+ and volume- and then plug in the usb cable (to your pc) do not release the buttons until you see the download mode logo on the screen. The phone has to be off before doing the procedure if it wont turn off , push the power button for something like 15 sec, should go off that way
Good luck and in the event that you can't go in download mode anymore , take it to assistance. It's the only way.

Hi I use a LG G3 and flashed a zip that was not designed for my phone (Validus-shamu-5.0.1.alpha.1.0-TEST-20141217-2151.zip) by a accident and rebooted, and now my phone has a black screen and the led is flashing red and blue (and said error: boot certification verify prior to that stage). How can I fix it?
Additional info: I was using the latest TWRP recovery, and own a d852 variant.
Any input would be appreciated! This is my only phone and I would like to resolve this as soon as I can.
UPDATE: i tried pressing power + up and now nothing reacts, even when i press other buttons. black screen. no LED.
UPDATE2: I removed the battery and put it back in, and now LED are back.
EDIT: FIXED. CLOSE THREAD PLEASE. got my solution from: "What you have to is power + vol down while off till you see the LG logo, then release then immediately press them again it should bring you to a factory reset screen select yes and you will boot into recovery." if people are interested.
I need help as well

Worked for me also! I just exited the factory reset menu and it booted up normally! Thanks for the help!
you're skating on very thin ice if you are flashing anything to your device that is not specifically for that model..

Thank You lazzarusbr!
You Sir saved me a lot of reading
This method helped me get out from the red-blue blinking, black screen Recovery ****up. I believe I got into it because I should have flashed the TWRP using KitKat, but my device came with Lollipop installed....

Mate, thank you a lot, you just saved my life.
I can't even express how thankful I am because my device almost got bricked and you just saved me. Thanks a lot !
It means not fully load.
Try to install the AUTORECAR in the Play Store.
Lol. The same thing happened to me on LG-D855. I flashed the TWRP recovery zip and new my phone is literally unusable. It doesn't boot into recovery or into anything else. Sigh.
Hi guys,
So basically the problems i'm facing is, I turn on the phone and it i'm greeted with the lg logo for a while then it stays on the logo. I notice the led light changing colours but it's still on the lg logo. Few minutes after that it restarts on it's own and goes in the same kind of loop.
What I have tried:
Used the flash tool with tot and the dll file to reflash the phone, but all what ends up happening is it will keep restarting.
Tried entering recovery mode using the volume down and power button but it never goes in, it's as if it has no recovery. The only thing that works is download mode.
So any ideas? the phone to me seems like it's booting and the led notification lights are flashing but it's just stuck on the lg logo.
Thanks.

I'm 100% sure it's in download mode as when I enter download mode it literally says "download mode" then the actual download mode screen comes up with the port that I am connected using and so on, so any ideas?

How does your PC recognize your phone if you plug it in?
Maybe you should (re)install latest LG Drivers and try again with flashtool. Which Flashtool do you use?
In my case of brick there was no Download-Mode anymore, just entered it and then after a few seconds a black screen with fastboot mode - so it looked like download mode but it wasnt, but i also didnt have flashing leds.

I hope you know to enter download mode your phone has to be off. The while holding the volume up button you connect your phone to your usb. It wont even show u an lg logo if that fails you try with volume down. If that fails then you will have to short circuit the phone
I was able enter download mode before I used that tool..now it just keep on bootlooping.
I think I have to try short circuit as u recommend.
Thanks for the help.
