LG G2 802 Soft Bricked - G2 Q&A, Help & Troubleshooting

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

Ok, this time hold volume up and power button constantly while connected to USB. Report back.

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.

Well, i tried this right now, the phone boots, LG logo shows, then it just goes straight into TWRP and nothing happens, i held the volume up, plugged the USB cable in (i could hear the sound in windows when you plug a device into your PC)

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?

What did you do before this? You need to give more details.
OK, I played me a little in the Hidden menu around, anything with factory reset test or so, since I can not get into download mode, although I get to TWRP, rom can flash and make backups back, but I can not start the system, it always comes short the LG logo and then it starts automatically in the TWRP, I can not do more, charging works
I hope you understand me,mei english is very bad!

sorry for the double post, now nothing works well
Have you tried to get into download mode? It's "vol up + power".
Sent from my LG-D802 using Tapatalk
Yep,but I can not get into download mode,only in Recovery(TWRP)
I make a Factory Reset Test in the Hidden Menu,since I can not do anything
vol up + power = LG BootLogo for a few seconds and then it boots into TWRP
I can flash ROMs and restore backups, but instead of starting to Android, it starts in TWRP
it is very strange

OK now clearly explain step by step what you did before all this happened.
e.g.
1. rooted phone
2. changed XXXX Settings
3. flashed XXX ROM/KERNEL
etc.
Ok,
i Have a LG G2 International Version D802.Stockrom (80210B)
I rooted the Phone and have Twrp installed,this works very well,i flash roms,make Backups since 3 Weeks,no Problems.
OK, yesterday I watched a bit and tried some things in the Hidden menu, the last thing I know I've got something pressed factory reset test
since then booted the phone does not except directly into the TWRP, I can turn it off and when I want to load it comes the Lg logo and remains,
Unfortunately I can not enter the download mode
in TWRP I can see that something needs to be on it but, Cache: 16MB, Data: 355MB, System1910MB, etc. ..
times can you please see if there is the menu? But press nothing
So as I said, I can charge the phone in the TWRP, turn on, turn off, unfortunately, is not more.
I hope you understand my bad English!

Download mode is NOT vol up + power. To enter download mode:
1. Connect a USB cable to computer or wall charger.
2. With the phone off, connect the usb cable to the phone while holding vol up.
It senses the power on the USB cable, and combined with the vol up being held it boots into download mode.
With that said, I would say Factory Reset Test tripped a setting to make recovery the default boot. I'm sure there's a way to undo that without flashing stock firmware in download mode... lets find it.

It takes a long time, i had this issue before, just enter recovery manually Volume Down + Power at LG Logo release and press again.
Then flash CM or something it will take a long time but it will fix it.
hey thanks for the reply.
i cannot access recovery at all right now... ill keep trying..
Any other thoughts?

ive been able to get back into recovery.
timing is very important for this as i thought there was something wrong, but holding down+power from the off state, see lg logo, immediately release buttons, then hold power key gets you to the factory reset screen. push power to reset, and then it boots into twrp recovery...
stuck in twrp
i accidently wiped everything in twrp. now cant boot into android, nor can install a zip. please advise how to copy zip files to internal sd card to install. please advise fast

Use system recovery in the LG support tool, before connecting the phone to PC turn off completly the volume up + power until U rich download mode. The plug and after PC installs phone, find the Recovery option.

Thanks to your post, I knew I should really give TWRP a chance to restore (which wipes system) and after like 15 minutes, it finished wiping system and moved on.

When you hold these two buttons and you see the LG logo, release and hold them again fast until you see factory reset screen. At this point press the power key three times and you will go to recovery. An press the thanks button here.

I think you have have to hold for 5 seconds to completely power down.
Hold vol- and power key and when logo pops up release power key and again hold power key then Reset screen should display. Press power until it starts factory reset which will dump you into Recovery.

maybe try to reinstall the usb drivers and replug the phone

Rooted my Lg G2, downloaded freegee, installed TWRP, turned off and wont turn on. no boot loop or anything. if I hold power+volume-down long enough it will flash a red LED but nothing else. will not connect to my computer. PLEASE tell me if there is any way to fix it.
Take out usb power. Switch off. Wait couple seconds. Press power button, and on LG screen press volume down and power at same time and keep pressed. Then it reboots into factory reset. Which is twrp. Wipe cache and dalvik and boot again.

The LG logo never appears.
ok turn off, keep pressing volume up, power cord in whilst pressing, do you get download mode? if so reflash kdz or update recovery via lg mobile suite.
if that doesnt work, try installing drivers on computer again, reboot computer, turn on phone connect, check if you can adb to it, then there might.be some how to adb recovery on it, as well as pushing a rom on it. maybe.
did you check twrp size before putting it on? also was it correct version for your phone version?

I thought flashing red LED light means that the phone is dead and needs to be recharged in order to be turned on again?

LG G2 Boot security error after trying to flash SuperSu after going to LineageOS 14.1

I've been using Cyanogenmod 13.1 (rooted) and I decided to flash a ROM with Nougat. 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
