[Q] Phone Constantly Reboots - G2 Q&A, Help & Troubleshooting

My phone is constantly rebooting without actually turning off. It's lost connectivity to everything (mobile networks, wifi) as well.
I rooted my phone and then tried to install TWRM on it. I may have installed the wrong version, I'm not sure because I used FreeGee to do this.
My phone currently turns itself on, goes to the lock screen then stops responding after a little bit then reboots. I can't actually turn the thing off to put it into recovery or something.
**Edit:** Alright guys, I've got it into download mode and am trying to reset to stock using this guide: http://forum.xda-developers.com/showthread.php?t=2432476

Nope, it goes back into its reboot loop. It seems that it's not actually ever turning off

This has happened to me before .I held power button for a minute or too at least untill it finally shut down..don't no if this will help or maybe u tried this already..

Please do let me know.

Any help would be appreciated.

Can you get into Recovery? Try a factory reset.
Factory reset worked.

This same thing just happened to me!
So frustrating! I was downloading a large game last night and plugged it in and went to sleep. When I got up it was off and I couldn't turn it back on. It froze on the Google logo. I tried holding power down to restart and same thing happened. Anyone know of a fix for this? I really don't wanna have to factory reset it. Btw its all stock, and not rooted or anything. Any help would be awesome, thanks!

Try plugging it into a different charger and see if it powers on, or into a computer and see if it is recognized and just acting weird.
Try holding power and volume down and maybe itll go into the boot loader... if not might have to take it back
Check this post. May help.

Not really actually. I helped my friend with hardware issues..he had to send his 7 in so we used wug fresh toolkit to flash stock and unroot then OEM lock the boot loader... google/Asus had no idea. I have also heard that if its bad enough shape(like won't EVER turn on) then they don't know I assume they somehow get the boot loader back on there and just reflash firmware.

Charge it for 2 hours then boot it up by holding the power button down for exactly 30 seconds.

Nexus won't turn on.

My girlfriends nexus won't turn on. She said the tablet randomly rebooted and got stuck on the boot screen. Now the tablet won't start. I charged it overnight and it won't turn on. I tried holding all the buttons in different combinations to try a hard reset but nothing happens. It's running fully stock. It's not even rooted.

Which version is it running?
Same thing happened to my sister's N7.....
If you can enter boot loader , then unlock it and flash either stock or CM. Otherwise u gotta call Google.
I think this is an issue with battery consumption and kernel. Cuz her battery had run dry and I think the OS failed to turn off properly which caused some kind of corruption! (Jus a guess so feel free to correct me)

The tablet is running 4.2.1 the tablet got the update but when I tried to update it I got an error message but that was days ago. I just hard reset it holding down the buttons.

[Q] Lg G2 won't turn on

My T-mobile Lg G2 won't power on and I can't tell if it is charging. I also can't enter download or any recovery. The phone was not rooted. Is there any way I can unbrick it?

First thing you should probably do is let charge up then see what works and what doesn't......then the help can come
Its been plugged in for about 8 hours. The phone gets a little warm so I thinks its charging but I can't tell. The screen was working yesterday so I don't think the LCD is broken. Plugging it into the computer gets no reaction.

Do you already try to push power button for atleast 10 second?
Yeah, ive tried holding down the power button. And I also tried entering download mode by holding volume up.

Does the pc recognize the phone at all?
No the PC doesn't recognize the phone at all. I tried installing the Lg Mobile support tool and the drivers but none of those can detect it either.

Hold volume up while plugging in USB. Should put you in download mode.

Turning the phone on

Hi, so the short story is that my phone power button does not work, and its turned of because the battery finished and now its charged, what can I do to turn it on??
I don't think ADB works cause phone is off...
Any solution??

Fix the power button
You could attempt just plugging it in and unplugging it a bunch, I have had some phones in the past that this works for, but if you are rooted I know at least one version of twrp recovery caused my phone to power on when plugged in and it would boot to recovery, from there you could just boot to os. Of course you would still need to get it to power on at least once first, so my guess is you need to fix the power button

Have you tried holding the button down for awhile? Like 15-30 seconds?

open phone, remove the power button board(its connected to the mobo with 2 golden pins, they just contact with mobo, so you can just lift away), and do a little short on 2 golden contacts on the mobo till phone turns on
Yes, i tried to hold it about 2 min, i'm sure this is hardware problem
