Hi everyone, pls. help..
I'm stuck in a bootloop, not a hardware issue but due to flashing a .zip file.
After flashing some mod through a .zip file, my G4 stuck in a bootloop and it cannot enter into download mode anymore. I can only access fastboot mode which is pretty useless since I have a locked bootloader and my adb access wasn't turned on previously.
I have a 818p G4. Pls. help!

download mode enter ..?
Turn off your phone. Press volume down and plug in USB cable to computer. Keep pressing until download mode appears.
Then you can do whatever you want but mostly reflashing stock kdz.

Failed, no luck. I think something's broken in the loading files and I can't flash anything since I have a locked bootloader.
I can do a hard reset but after it boots, it's stuck at "Android starting apps."

Why do you keep it bl locked? For warranty?
Then you can ask for a repair saying system files have been altered blah blah your phone isn't booting.

Search for Lg Flashtool 2014 . Get the kdZ în the folder of Lg flash tool . Start the software put it în Cs-emergency and then try to flash the kdz. This should work on bricked phone with no download mode

What model do you have?
For a locked bootloader, download mode is very important. Otherwise, you can't flash anything so it's already a hard bricked device.
Waiting for other suggestions..

Hello,
I made the mistake of starting the update At&T had put out for the LG optimus g pro today and now I can't get passed CWM Recovery screen. IT won't connect to the computer even though I have the drivers installed. How would I flash back the original rom or even putting a new one on there?

Using hardware buttons the try to reboot or download mode.
Restore using the AT&T Factory TOT. I had the same issue with TWRP. Please review my thread as it will give some insight on how I recovered. As long as you can see the LG boot screen then you are safe.
HI, When I try to use KDZ to flash the firmware stock ... it starts but suddently like 2 minutes the phone turn on . On the bootloader where I can select if turn it off, go to recovery .... Why Kdz doesn't work flashing the system ?
Just restart in download mode don't interrupt the flash it will work after few tries.
Can't confirm but I think having a nexus bootloader does that

I unlock my phone bootloader today with freegee. I update my phone firmware to newest version and found that old kdz is not available to download anymore . It appear to give kernel panic after reboot. But you can install custom rom to get rid of this kernel panic problem (You must install recovery after unlock to do this).

1: freegee doesnt flash nexus bootloader
2: restarting to download mode resume flash, as it did for you. (only if you have nexus 4 bootloader)
3: any other problem is your problem.
Well, let me explain what happens...
I have an LG Optimus G, which I've rooted. I wanted to install CWM, but I didn't read at the tutorial that this wouldn't work with the bootloader locked. I restarted the phone and it tells me a "Secure Booting Error".
I can access Download Mode, and there I've tried the LG Mobile Support Tool, which always tells me that "Battery is low". I've tried unplugging the battery, but the same. If I could bypass this error, probably I could have again my phone alive. I tried using also the FlashTool, but it says the kdz is corrupt (>1GB) and when doing a test upgrade, it shows again the battery trouble.
What should I do? Shall I buy a new battery? Or is there any other method to bypass this message?
Thanks for your time and your patience.

I can't enter into download mode. Whatever key combination i tries to enter download mode or fastboot mode or normal boot it just show me a error:
Secure boot error

Cause: Device Unlock, So boot success
and Goes into recovery mode where i could not select any flashable zip files to flash. There's another error: E:/ Can't mound sdcard.
Cant mount data..
Anybody knows how to solve this?

It's not just a key combination... To enter download mode, you should turn off your phone (hold Power for >15 sec), then hold both Volume buttons and connect the phone by a USB cable to your computer. Is this exactly what you are doing? And it's not working?

I'm glad that you got your phone back. My succession is that don't use Marshmallow Autorec. It's buggy I guess. Just root and install recovery on Kitkat with Kitkat Autorec and then flash Marshmallow ROM in development section.
