Problem: Power button is not working on my D800. It doesnt turn on or off when I try to click on it. If the phone is off, the only way to turn it back on is plug in the USB. However, the phone still reset if I hold it for like 10sec. I can't get into recovery by holding the power button and down.
History: The phone was recently bricked into qhsusb_bulk mode. I followed the instructions on this board and re flashed some files. I think this is when the power button stopped working. After that I used LG Flash tool to restore to stock 4.4.2.
If anyone can help, I would very appreciate.
plzzzz help mee

Ok so, I was going to flash CM 9 v1 on my device, and when i was in clockworkmod recovery I noticed that the power button wasn't working at all.
I took out the battery and put it back and then it reboot itself and got stuck on the unlocked padlock screen.
Then i managed to boot it by pressing vol up and down at the same time and putting the battery in when plugged on the computer with the usb cable. This is the only way i can boot it. And after it runs a while it crashes and reboot into the unlocked padlock again. And this over and over.
Then I tried to go to recovery to reflash with the soft sensitive buttons and the fastboot screen doesn't do anything at all. If I press vol up or down to move around it gets stuck.
Got it to work a while and reverted back to stock rom with rom manager to see if fastboot worked again but nothing happened.
I need help to fix this.
I try to go to download mode but it doesn't work either. ADB works tho
Any suggestion??
(sorry fot the bad english)
i actually had the exact same issue a few weeks ago
it was an issue with the power button itself since i got everything back to stock and the power button still wasnt working properly
i had to send it to samsung repair center
they fixed it for free and it turns out the issue was indeed the power button
thank you for your answer!
i will send it to samsung!
So I tried getting Cyanogenmod 10.2 for my LG G2 (D800). I did some stuff and ended up rebooting and getting this screen.
[650] Fastboot mode started
[700] udc_start()

I used TWRP for backup, but can't even get into phone to do anything.
Also it won't come up on my computer when I plug it in with usb. I tried both my computers and they both had the drivers but the phone won't even connect to either pc. I could connect easily the day before though.

I also got this while pushing Power and both Volume buttons at same time.

What should I do? :crying: If you guys need more info or pictures just tell me, I'll do anything to fix my phone.
Hold power down for 15+ seconds. Then hold volume up and plug in USB. This should get you into download mode to kdz. May take a few attempts.

I see your using Utorrent you pirate! JK
It looks as if your phone has some life left, not really too familiar with D800. Have You tried the key combo to get into TWRP? Does the D800 have download mode?
Also did you by chance flash the wrong rom (different carrier)? Did you wipe the internal storage?
It looks like the incorrect ROM was flashed, it did not like your boot.img. You should be fine. Hold down the power button for +-15s as he said. During that time the screen should turn off, back on to the LG screen, then back off again. The phone should stay powered off. Then, hold the vol- & pwr buttons, releasing them when you see the LG screen. While still on the LG screen, press and hold the power button until you arrive at the LG factory reset menu. Press the power button to confirm a factory reset, which will actually boot you into TWRP so you can restore your backup.

I got it to work again! Thanks everyone for helping me, I'll try not to break my phone again :laugh:
Thank you for these threads

I have the lg g2 d800 as well and I also had a similiar issue. I wiped to clean for new rom and accidently before installing cm-10.2 I hit the reboot button. I just want to say thank you guys for all the knowledge base. Reading this thread fixed mine too.
I had similar issue couple weeks ago bad flash,no backups and unable to mount sd from custom recovery, the only way for me to fix this was to install rom via sideload, which was pain for two days.

Hi
did no work also
I am having the same problem, went to lg service centre, they could not enter download mode as well. I might need to change the circuit board for $321 singapore dollars..
Hi
i think you have to use this fix: http://forum.xda-developers.com/showthread.php?t=2582142
This happened to me,
Try holding the power and volume down hold until lg logo, let go and press and hold the volume down and power again, it should get you in recovery.
It might get you into a screen called "Factory hard reset" Agree using the power button, and it should take you to your recovery, and try flashing a ROM along with the Gapps (if you want, which I did) and then I used a recovery file after booting back into recovery to restore it to my previous state.
Good luck :good:
Shut down phone
From what I got from this, you're having problems shutting down your phone, correct? It keeps booting back up after the screen goes black? If this is the case, hold the power button (and don't let go) until it goes black, reboots itself, then goes black again. Shouldn't take more than 2 seconds after rebooting to shut down. Then, you can do volume up + USB to get into download mode.

Lg optimus p705 l7 bootloop
Hy guys, my LG p705 stuck in lg logo (Bootloop) and it can't go to recovery mode
can someone help me to fix it?
i already use kdz flasher and LG Mobile Support but it not work for me
my phone is not rooted
hi there
i have same phone
if you have the KDZ and Drivers do as what i did
make sure you installed driver and the KDZ updater is working fine when you try update and say phone not found
now your phone will need to be in Emergency mode and to do that you need to hold vol + then hold power while you holding the vol +
the back and menu should flash then phone vinrate you must relase keys right after the phone vibrate it should give you yallow screen i made a short record while im geting my phone into Emergency mode in Attached files
when that ready you can start flashing the rom to your phone after the KDZ done it may give you error in windows that KDZ stopped working nevermind that the most thing we need is to see the phone starting up in the boot screen LG and you hear the sound
after that you need to do hard reset to the phone in order to work and not stuck at boot
1- turn the phone off remove the battery and put it back again
2- to do the reset you will need just hold vol + vol - and the home key then press pwoer while you holding the 3 other buttons and hold the power key also till phone is vibrate then release keys when LG logo appear
after reset your phone should back normal like mine
