VS980 Stuck on LG logo, no adb or fastboot

Hello, I have seem to soft-bricked my device. I was installing a ROM using TWRP (I forgot the version) and it was taking a very long time, then I stupidly shut-off my phone, and when I turned it on, it was stuck on the LG logo. I cannot boot into recovery using Power + Volume Up button, and I have no idea how to fix this!
Thank you.
EDIT: Got into recovery. The whole /system was wiped, I re-flashed CM10.2, now stuck in boot loop of the Cyanogen Mod boot logo,

It would appear that I did something very similar and is stuck at the logo boot loop. How were you able to get back into recovery?

Do you have the LG bootlogo coming up, if so try this:
Turn off phone, then when off, hold down power and volume down button until it reaches the LG logo and then release and hold it down again, if that doesn't work, when just hold it down until you see a screen that says something like: Hard reset/ factory reset. For me it took me to my recovery screen, where I just flashed a older ROM onto it. I then later flashed a recovery file. I hope this helps, and if you need it any clearer, just reply

Thanks for the reply! I was able to get into the factory reset but had to follow slightly different instructions. The way I've seen it on most wiki sites is that you hold Volume Down and Power button at the same time until the LG logo shows up, then release them and press them down again. This never worked for me.
What I had to do was hold Volume Down and Power button until the LG logo shows up, then release ONLY the Power button while still holding the Volume Down button, then press the Power button again. This method got me into the factory reset consistently and was able to get back into recovery.
Best,
Colin

LG G2 VS980 not booting, system folder permission is changed accidentally
My LG G2 VS980 phone was rooted by myself. It was a factory unlocked phone. Then using Root Browser by JRummy apps i have removed some system apps and just for a try i have changed the permission settings of system app folder to ro. Then on reboot my phone was stuck, it turns ON and after LG and Verizon logo, says "unfortunately, phone has stopped" and i could see some basic apps such as file manager, calculator etc. but i cannot use the phone at all. It is stuck. How to get back to the original factory unlocked condition? Any ideas plz!

LG G2 802 Soft Bricked

Hello.
I have an LG G2 802 that i managed to royally screw up last night, I was about to install the new firmware update for my phone, completely forgetting that i had a custom rom installed on it. After the firmware update was finished downloading, the phone rebooted into TWRP and would not boot normally after that, could not boot into the previous custom rom i had installed... I decided to wipe all the data, and try to use an old backup i had laying on the internal storage, got to it, wiped all data and started recovering the old backup. But the revovery wasn't working properly and it gave me an error, after fiddling around with TWRP a little more, i went into wipe -> advanced wipe -> and wiped everything, because i had an idea that i could just force a new rom over by ADB from my PC, and this all resulted in that I have no operating system, the phone boots into TWRP all the time, I've tried to hard reset it, but it just boots into TWRP whatever i do
Please help

Just flash a new KDZ over it. And next time check XDA if someone had the same problem as you and you will find the solution.

I've done a quick search about flashing a new kdz, and they involve getting into download mode, I can't access download mode, it just sends me to TWRP no matter what i do

Are you able to boot into download mode?

Ok Hold the power button until the phone flashes twice and then let go off the power button. When it's off, hold volume up and then connect it to USB simultaneously.

I just tried doing that, held the power off button until the LG logo flashed twice, the phone turned off, and then i held volume up button, LG logo appeared and then it just went straight into TWRP

For those who have similar issues, I did the below steps:
1. While connected to computer in CWM recovery, install the drivers via PdaNet (these replace any original LG drivers)
http://forum.xda-developers.com/show....php?t=1983470
2. Connect to phone via ADB while still connected in CWM recovery (see below ADB download if you didn't already have it or forgot where it was)
http://forum.xda-developers.com/show....php?t=2317790
3. While connected via ADB you can use the same method as in the below thread (use the first one).

Tried it, it turns off, then the notification light at the top of the phone (beside the front camera) blinks 8 times if i constantly hold the volume up and power button, as soon as i release power button and volume up, the phone boots with the LG logo and then goes into TWRP.

What he meant was, hold the Volume Up button & connect the phone to your PC. Don't have to hold power button at all. Try this mate.

When the notification LED starts to blink, let go of both buttons for a split second and hold them back again. Make sure USB is connected. Since you have TWRP working, Download should also be available.

The problem is that you have to have the phone off to even attempt to get in to download mode.

If i try to power off the phone WITH the usb cable connected to it, it just reboots automatically, so i cannot power off the phone without it rebooting all by itself, and then going into TWRP.
I tried to hold volume up and power while my phone was in TWRP and it rebooted, LG logo came up and then the red notification light started blinking, then i tried to do what you told me to, quickly release volume up and power button, while the LED was blinking, but nothing happened, other than the phone just rebooting, and then the LED started blinking red again, this just looped over and over again...

Turn it off, hold volume up and connect USB cable. Does it go to download mode?

I had the same problem, stuck on logo lg , when i tried to go to download mode, i got stuck in the first step of it (i can't see the step with firmware update etc...) and when i tried to make a factory hard reset, it goes on the recovery mod.
After seeing many forums since 3-4 days, i tried to flash the kitkat kernel, so i used the adb sideload ---> so connected on recovery mod, then make install from sideload, then on your command (on windows) type adb sideload thenameofthekernel /sdcard/ and normally the recovery should install himself the kernel and you can reboot your phone
I still have an issue, can't access on download mode but i can use the phone as before, so if anyone can help, i listen you ^^

Hold down the power button till the it turns off and keep it held down the LG logo will flash up again then go off after that release it and wait a few seconds making sure the phone does not boot up again. Then hold down the volume up button and with the usb connected to the computer plug the USB into the phone this should then put it into download mode.
Why don't you sideload a rom in twrp recovery via adb?

[Q] Please help! Stuck at LG Splash screen on boot

I am rooted and had PhilZ recovery installed on the vs980. I wiped data, cache, and davlik to install a new rom, but the install failed. After the install failed I realized I had deleted my backups I had. When I went to reboot the phone said it could not find root and would attempt to root on its own or something of that matter. I am now stuck on the lg spash screen with the led blinking green/blue. I cannot boot into recovery or download mode by holding the volume+power buttons the phone just vibrates and turns off for a sec then right back to the lg screen. Can someone please point me in the right direction. Thanks in advance

Yeah try booting into recovery but a little differently this time.. Turn the phone off, hold power and volume down to turn it on but keep holding it until it shuts off again. Then press power and volume down again until the LG logo appears. Release and press them again quickly like normal. This has worked for me in the past when I couldn't boot into recovery. Idk why but it did.. Give it a try

When my phone loads up I get Enter PIN/password to decrpyt and after about 3-5 mins it starts clicking. I have restored it back to stock but the decryption screen is always there.....Is my phone knackered?

Thanks alot i figuried it out

same problem
Hi guys,
I have the same exact problem, restored my rom with LG Flash tool 2014, but now it's always asking me this pin/password. And I tried all combinations with volume up/down and it's impossible to go in recovery, what can I do? My LG G2 is a european model 32 GB

this is the screen I'm always getting

Same Problem Here
Hi,
I'm having the same problem.
I have an LG D802. I was on CloudyG3 with TWRP recovery. While using the phone, I noticed a yellow tinge in the right side of the LCD. So I figured, I'll show it to the service center and get the issue sorted out. Obviously, I couldn't take it there rooted and on a custom ROM as they would annul my warranty otherwise. So I decided to unroot it using the LG tools. (I have done this before too. But I did not face any such problem back then).
This time, it is taking me to the screen and asking me to enter a pin/password to decrypt.
I tried booting into recovery using the old method (volume_down + power and LG logo flashes, release and press power again, then 3 times power) and also tried another method as recommended by someone above (volume_down + power till LG logo appears and then release power and press volume_up). None of them work now. In the first method, the screen just goes blank for a few seconds and the phone reboots while in the second method, the phone boots into safe mode.
Kindly advise on what to do. I am stuck and my warranty expires on the 18th of November.

Problem Solved
Earlier when I was using the Flash.Tool.1.0.54, it wouldn't ask for region and language in the pop-up. It would just open the LG Mobile Support Tool and then I manually selected the Start Upgrade button to flash the phone. The problem with this was that on boot it would ask for pin/password. I couldn't even boot into the stock recovery for some reason.
Then I used the LG Flash tool 2014: http://forum.xda-developers.com/showthread.php?t=2470207
There was a region and language pop up and it proceeded to install the firmware.
But on boot, it still asked for the pin/password. So I tried to boot into recovery and it worked this time! Pressed the power button 3 times and it wiped my phone.
On reboot, the phone worked perfectly without asking for the pin/password. But, now it was reading my internal storage as only 16GB. I followed the directions in the link provided by @Alexxxx to repartition the internal storage in my phone. Here is the link once again: http://forum.xda-developers.com/showthread.php?t=2470207
It worked perfectly for me.

I flashed lineage-14.1-20170320-nightly-d802-signed and open_gapps-arm-7.1-mini-20170325 and everything worked fine except I didn't have SuperSU. I tried flashing SuperSU-v2.79-201612051815 and when I tried to boot into system I got this screen (with the LG logo below) http://i.imgur.com/O7vOtab.png I tried many methods like this https://forum.xda-developers.com/showthread.php?t=2582142 and this https://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 to no avail. In Linux when I used the ls /dev/sd* command in the terminal the phone wouldn't show up and later in Windows I got the PC to recognize the phone as Marshall USB Composite Device 9006 http://i.imgur.com/a5WHV9P.png and in Disk Management the phone partition shows up un-initialised http://i.imgur.com/XaVKIu7.png . Help I don't know what to do now. Tell me if I should provide more information.

I had the exact same problem. Then i found a solution. Just dont flash the normal Supersu, you need to flash the Supersu BUMPED file. Just go in recovery, press 10 sec the power button to be sure the phone is off, then hold volume down and power button until the logo appears, then release and press again (fast) then choose yes, yes. Just flash the Bumped and if recovery asks to do root choose NO.
The Bumped which worked for me

Yeah Bad same Problem, turned off and it went on, then again bootloop. But if you press the power button long enough then its completely off. In cyanogen mod i had Problem that i couldnt get into recovery with power button+volume down.
So you should flash kdz, get oneclickroot for LG g2, then autorec lollipop to get recovery. Then flash Rom + gapps + The bumped file.
If you dont know how to flash kdz, you can ask here. I will help
Good luck

Previously I couldn't go into download mode but I will try now since I managed to turn off the smartphone completely. Before it would just stay on with a black screen.

Yeah Ok. When I wanted to turn It off, I just pressed the power button until the screen went black and the logo came again but after 2-3 sec the screen went black again, then it was off (just hold power button for 10sec)
Try that when your phone keeps restarting

KDZ flashing gets stuck at 60% (Verifying phone connection) http://i.imgur.com/AAHKqcd.png
Should I just let it sit through its emotional problems?

Get the lg mobile support tool, install it. Then open and connect your phone via download mode, it will find the phone and download the kdz for it. That should work.
If it doesn't install automatically, click on additional options then click on set upgrade error back, or something like that.
Before all that install the driver from

Then you can start with lg mobile support tool
