[Q] How to manually turn off - AT&T LG Optimus G

This might be a stupid question but because the battery of this phone is non-removable, how do you manually turn it off or restart it in case it freezes up?

Hold down the power button til it restarts. There's also a basic tear down guide on how to do a manual reboot posted out there.

so even if it's frozen if you hold down the power button it will still shutdown? good to know that, I'm gonna search for that tear down guide..thanks

Both volume buttons plus power for about 10 seconds simulates a battery pull.

power button broke so i reassigned it ;)

Tried to turn on my XDA yesteday and the button fell into the device ! This caused not to be able to turn on the screen unless I got a call. I downloaded Vito SystemTools' button maping program which allowed me to make my calendar button (when held down) to turn the screen on and off. The problem is that turning the screen on and off is not doing the same thing as the power button did. I was under the impression that all the power button did was turn the screen on and off to save battery and prevent unintended input. However, now my battery dies in 6-8 hours of use compared to the normal 2 days. Obviously, there is somthing more that the power button does.
What I'd like to know from the developers is if there is a program called by the power button and how I should access it. The button mapper program allows me to map any program I want to (almost) any hardware button (not the volume button). If it's a DLL or somthin I can probably write a wrapper program for it with some pointers.
I'm also in the market for a dummy xda or just another power button if someone has one just to get it to look better. However I like the functionality of holding down the calendar button for 1 second to turn the device on/off and would like to keep that permanently.

The power button is probably hard-wired to some processor wake-up logic. So when you turn the processor off, it's going to be very hard to make it wake up by anything else. You could write something that makes it wake up very very momentarily, say every few seconds, to check for a button-press. But my guess is what you want is a new power button.
damn Well i'm waiting on a dummy phone auction unless anyone over here has one to sell me.
I got exactly the same problem, the only difference is that i managed to get it back and i putted some silicone glue in it. It works and don't ask me how ;-)
Anyway, why don't you just press on the call - hang-up , calendar, volume button to wake the phone up?
Than just change the settings in battery power to make it shut down after 5min or 10min. It should help you reduce your battery life time since the phone gets automaticly in sleep mode after that time.
good luck,

I have my phone set not to wake up without the power button being pressed. I can turn this off but then buttons get pressed in my pocket since I don't like belt clip holders.

HELP, Galaxy Tab won't on, need help guys :(

I have a TAB 10.1, that WONT turn on, and WONT charge, I don't have the receipt as I have received it as a gift, however Samsung took it for repair AND DID NOT REPAIR IT ! Very disappointing!
Is there any other solution to fix it, when I plug it into the computer still nothing...
Please get back to me guys, need your help, thanks
did you tried holding the power button a little bit longer?
It happens from time to time. Just keep it charged and try to turn on from time to time (sometimes holding the button for multiple seconds). Eventually it will turn on. It's the standby of death problem.

yes, I tried everything, holding power down for up to a minute, holding power and volume up and down, also holding the power button while touching the screen, still nothing...
Try connecting to computer.
Or maybe its Sleep of Death issue. Search for it. you will get solutions like draining your battery completely.

Did you try Power button, then volume down button (only, don't touch the power up) for 8-10 seconds while still holding the power button, then letting off the volume down button? It always works for me.

Phone bricked without ROOT

Hey guys wondering if anyone experienced the phone being basically bricked without actually unlocking, rooting or anything.
It has happened before one, just laying on the table and the phone turning off but it came back on after a while.
Today it occurred again but has not turned back on for two days. When charging the only light is the LED flashing constantly every second. If I hold the power button and volume up then the flashing of the LED changes pace to One long flash (1 sec) to two quicker flashing ones (.5 seconds). If I unplug it and plug the phone back, The LED flashing is back to the original constant pace.
When unplugged sometimes holding the power and volume up button initiates the LG logo and then turns off and then shows the logo once more and then turns off for good.
If I plug this into the computer, its like someone ejecting a usb and plugging it in like a maniac. I heard the connecting and disconnecting sounds from windows nonstop like as if its about to blow up.
I've tried holding the power button for a minute the same goes with different combinations with the volume buttons.
The only thing I haven't tried is opening the phone, kind of afraid I will mess it up. Any solutions?

Never heard of this but I can throw a few suggestions out. Try unplugging, then holding both Volume buttons and the power button (All three) for about 10 seconds. Try different USB ports.
Try this if all else fails: Source: http://cellphoneforums.net/lg/t348484-perform-master-hard-reset-lg-optimus-g.html#axzz2YPtvkfDk
To Perform a Master Reset via Hardware
1. Turn off your device.
2. With the device turned off, press and hold the Volume Down key as well as the Home key at the same time.
3. While both the Volume Down key and the Home key are held down, press the Power button.
4. When the LG logo appears, release all the keys.
5. Scroll to and highlight wipe data/factory reset by pressing the Volume Down key. Then press the Power button.
6. Scroll to and highlight Yes – delete all user data by pressing the Volume Down key. Then press the Power button.
7. As soon as the wipe has been completed, press the Volume Down key to scroll to and select wipe cache partition. Press the Power button when ready.
8. As soon as the wipe has been completed, press the Power button to select reboot system now.
9. The master reset should now be successfully completed and your LG Optimus G should restart.

LG G3 rooted, twrp, Xposed, will not reboot without removing battery?

Hello,
Since rooting the phone it will not restart without pulling the battery.
If in Xposed "soft reboot" or "reboot" both turn the phone off and it will not respond to button input to re-start
If pressing power until power off menu comes up and I press reboot, it shuts down and will not re-start until I pull the battery.
If I plug in the power while it is in this state it will not charge or start
Once I pull the battery, it will:
Charge without starting when plugged in
Start with power button press
All else acts normal.
Any ideas? I just hate taking the stupid case off and pulling the battery any time I have to re-start!
I haven't narrowed down what causes it, but I've eliminated a lot of things:
http://forum.xda-developers.com/verizon-lg-g3/general/rebooted-140-times-attempt-to-narrow-t3251949
Just for clarity, it more than likely isn't actually "off", it's rebooting and getting frozen with a black screen. Besides pulling the battery you can also long press the power button (10 seconds?) to force it to turn off, then turn it back on again. I usually just pull the battery too because it's quicker.
Yeah, no the long press doesn't do anything no matter if I leave it pressed for 5 seconds or even 45 seconds (Tried that several times)
Leaving it alone for an hour doesn't do anything. If anything I'm doubting that it turns all the way off rather than gets stuck rebooting. It is absolutely frozen until I pull the battery.
Here are the only things I have found which works to avoid taking the phone apart:
From Quickboot: Power Off (do not reboot, do not soft boot, etc, just power off) (quickly powers down, almost instant)
or
Press and hold power button for menu: Power Off (longer time to power down)
From either of those, the power button turns the phone back on no problem.
No rebooting works.

Recalcitrant power button

To use the power button I have to press it firmly and hold for a few seconds, which works tho sometimes causes phone to skip right thru power on to screen off, or the like. Can I fix this with a new power flex cable and/or power button assembly? Or is it just life and I should go on this way - it is not life threatening.
