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?

So i think you should flash original KDZ for your LG variant, and from clean rom start flashing custom roms.
PS.: Sorry its one month but i couldnt write before, i hope you have resolved problem, or i helped rit now.

So you were able to tot back to which version?
Your phone is still identified as ls980. If you have zvc, use ioroot25 and auto-rec to get recovery.

Thank you my friend for your respond but I changed my phone...My ls980 I had unbricked it I sold it..Now my phone is lg g2 f320...
I would root and auto-rec, but all the root methods I have found require a recovery mode. Even when plugged into adb, the phone will not force into recovery. Is there a way to root without recovery mode?
Thanks.

Ioroot 25, will do the trick. Airplane mode, USB debugging on. No recovery necessary. Then install auto-rec and run.

I want to restore my stock LG E975 kdz after using a custom rom and CWM recovery. First I put the phone in download mode, run KDZ FW UPD tool and it begins to extract kdz file. But as soon as it begins Param 1, the phone enters recovery mode and the upgrade program loses connection.

when your phone exits download mode & goes to fastboot while using kdz updater unplug usb & enter download mode again without closing kdz updater. it should finish the update process.

For anyone else with the same problem:
I got stuck in a boot loop with the LG logo after flashing the kdz, likely due to the unlocked bootloader left by the custom roms.
I fixed that by doing a hard factory reset (volume down and power button). all fixed

Hi everybody,
I have a BIG problem, with CyanogenMod 11 - Unofficial. I installed the 05/13 update and at the beginning I only had problems with the volume bar and the reboot panel: it shows kinda grayish overlay and the only way to make it disappear was to press the backward button. So, I tried to flash back the Stock Rom, but something has gone wrong... I still have CyanogenMod 11 - Unofficial, and the gray overlay is everywhere, anytime (I managed a way but limits phone usability). Moreover, key combinations involving the power button do not work, and I'm not able to do anything like Recovery boot or Deep Reset...
I need your help!
Thanks in advance

That's a bug from the old version, so press all buttons until the phone reboots and hold them until the you see the Huawei logo. Than it should boot TWRP and from there you should restore a backup or flash a new ROM.

By all buttons you mean Vol+ Vol- and Power together, right? With unlocked screen I assume... Last question, I have to do that unplugged from charge?

Yes I mean that button's. And no it don't have to be unlocked the screen can also be off, and it don't matter if you have it plugged into the charger.

Ok, I tried, but it doesn't go any further than Huawei logo... :crying:
Since you are stuck at the logo, that means you are in fastboot mode ans you can try to install stock recovery and boot .img files than try to install the stock roms

You were right, I was in fastboot, so I installed the stock recovery and the boot.img from surdu
http://forum.xda-developers.com/showpost.php?p=51718316&postcount=2
because I supposed I was on B510, but now when it starts, doesn't go any further than the Cyanogenmod animation...
what can I do now, I'm not able to find the device on adb or fastboot...

Since now you have stock recovery you can install the stock rom, and if you want to go on custom rom it should be easier to do it.

So there is anything I can do? How to deep reset? I've already backupped all the data that I need...
Hm... how long do you hold that 3 buttons? It can last around half minute to get to the stock recovery... You should put sd card to another device or adapter and put stock firmware on it then back to p6 and hold 3 buttons combination untill recovery apears

When you say "stock firmware" what do you mean? the zip file with the stock rom? or the boot.img file?
The zip file with the stock rom.
Do I have to mention that you have to unzip downloaded file and put: /external_sd/dload/UPDATE.APP ?

I know it might be a stupid question, but "external_sd" should be a folder which i create like "dload" inside of it, right? :angel:
Well actually this is SD card.
Nope guys... I tried all the possible combination but TWRP doesn't start... it's stuck on huawei logo, with red charging led flashing and i'm not able to fastboot or adb
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.

Thanks for the tip buddy but this can only be successful if you have a working download mode. My download mode is broken.

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..
