hello
i have an unlocked boot loader and rooted optimus g E971. today i flashed rom kitkat 4.4 everything went well no issues. I decided to go back to my back up and reflashed my stock rom once again everything went well. i noticed i was still rooted when i went back to stock but wasn't when on 4.4 which is another topic later. anyways i decided to install rom manager to experiment and i had stability issues with it. i noticed the phone would crash and reboot with secure booting error, i was able several times to restart phone and use. Now the phone cracshed before i could delete rom manger and im stuck on secure booting error. I followed this guide http://forum.xda-developers.com/showpost.php?p=44874388&postcount=36 however the problem is i can't get into download mode or recovey... Phone does nothing but say secure booting error,boot certification verify. trying numerous times nope not happening .after reading several posts im assuming this is all because the bootloader was not unlocked after reflashing back to stock.. is my phone garbage or how can i fix...pls help :crying:
This means you didn't unlock the bootloader.
To enter download mode,turn off the phone,then press vol up+vol down at the same time and plug the micro usb cable to pc. You will enter download mode. After using kdz updater,make a hard reset by turning off phone,then press vol down+power at the same time,until the hard reset menu will appear. Press power twice to confirm and that's it. A new stock phone.
After this,you can root and unlock it again. Just remember to put somewhere safe the freegee folder after you unlock.

Press just the power button for a minute
Now press both volume buttons and plug in the USB cable. It should go into download mode.
If not press power again for a minute and plug in charger and see if it shows regular charging animation.

Hi guys. Im pretty experienced with android but this one has me stumped. My buddies brother has a stock/non-rooted optimus g e971 on Rogers. He changed his screen lock password and forgot what it is. Of course he never register a Gmail account so I can't recover that way. I figure no problem. Shut down, pwr+vol down to factory reset. Well nope doesn't work. It flashes the lg logo twice then boots like normal.
Ok so I figure I'll just put it in download mode/fast boot to do the factory reset. Tried pwr+vol up. Nope. Vol up+vol down+pwr. Nope. Vol up+vol down and plug usb+pwr. Nope. It just flashed the lg logo twice then boots like normal. I've tried multiple variations of each holding the pwr for different lengths of time, always with the same result.
Anyone have any suggestions? It's not bricked, and the vol keys are working, it just won't go into any modes.
also I dont know if he has hardware encryption enabled (of if thats even an option on this device) but would that even prevent me from getting into factory reset / download mode?
Also I check that the vol rocker is working. when it is on but screen is off, if i click the vol rocker either way it wakes the screen.
I have a similar problem.Here's a thread I made about it http://forum.xda-developers.com/optimus-g-intl/help/enter-download-mode-t2883542.A couple of guys had some ideas.None worked in my phone but maybe you're luckier.
If you haven't done that already you should try going into download mode by pressing power up+down and plug the cable, don't press the pwr button.
If you find a solution pls let me know .
Yup, you shouldn't need to press the power button for download mode.
First, make sure you have the LG United Mobile drivers installed on the PC you're using. Then plug your USB cable into the PC (not the phone yet). Simultaneously press and hold the Vol +/- buttons, and hold for 10 seconds. Then while still holding the vol buttons, connect the micro usb to the phone.

Doesn't work either. If I hold +/- for 10 sec then plug in the usb it flashes the lg logo twice, then goes to the battery charging screen. If I hold +/- for 20 sec then plug in the usb it flashes the lg logo twice then boots like normal.
after reading this post i went and tried if i also cant get into the recovery and the same happened to me, the LG logo just flashes and nothing happens. mine is stock E975 (4.4.2).
worked for me.

Android has SD card encryption disabled by default - but if it was enabled it shouldnt disable recovery/fastboot - right?
Even if the bootloader is locked, i should still be able to get into fastboot/download mode, and/or recovery, right?

That's what i figured, but i didn't know if there is some quirk with this device i wasn't aware of.
Is it possible i have a corrupt boot loader? Again this device I'd completely stock.
anyone?
Hi
I'd be really really grateful if all of you clearly (more) knowledgeable (than I) could help me.
My phone is a D855 (32gb/3gb) international model which was running on stock v5.0.
I ran v1.3 of the one click root method. and completed the whole process (or so I thought ). However, after the process said it had completed, I removed the usb cable and now find that I am stuck at the LG Logo.
Pulling the battery makes no difference. Once reinserted and power back on, the LED on the top left blinks but no boot.
I have tried to enter download mode (by removing the battery, holding the volume up button and inserting the usb cable) but again, no joy.
Can anyone please tell me what I need to do recover the situation.
Many many thanks
Update: I managed to get into recovery by turning off the phone completely and then pressing and hold Power and Volume Down. When the LG logo appeared, release. After a split second, then pressing volume down and volume up. At the white screen asking you to reset, I pressed Yes two times using Volume buttons. Saw the screen that said erasing data but still stuck at the LG logo.
Can anyone help please?
Update 2: managed to get into download mode by powering down (took the battery out) then holding the volume up button and inserting the usb cable.
What do I need to do next?
hello, you need either the lg mobile suite software or lg flash tool 2014 and a kdz
I would go for lg mobile suite - it will offer an upgrade or select it manually
also -- see the guide from hyelton in g3 general (getting back to stock)
got an lg g4 that works fine however it refuses to go into download mode. volume up and power button does nothing.
And What is With Fastboot?
Where do you got the LG from`?
maybe a Frankenstein.

Take out the battery and put it back on the phone.
Connect the phone to the computer while pressing volume up. Keep volume up pressed until you see "download mode" screen.
Hi.
I have an LG G3 Verizon.
When I press power button LG logo appear but after 5 seconds it automatically turns off but after it turned off it does not turn on even puting battery out and in then i have to wait couple of mints when i have been able to do this again. I can go into system official recovery .But when i try to go into download mode by connecting with computer,mobile shows that it is going to download mode but it again turns off and same thing happens and i have to wait for couple of mints.Similar thing happens when i try to factory reset or any option in download mode
