LG G3 Won't turn on - G3 Q&A, Help & Troubleshooting

Hi everyone,
I have an issue with my LG G3: the phone won't turn on.
So far I tried the following procedure (but no luck): pull out the battery, press the power button for 30 secs, plug the power cord in (nothing appears on the screen, not even the "no battery" warning)
Is there anything you can suggest?
Many thanks!
PS: this did not work as the phone is not recognized by the PC at all.

weird ttrick
Someone put this on another forum wish I could credit properly. G3 is famous for power button failure. Put battery in then plug in the charger and as soon as you see the empty battery with loading icon unplug the charger. You have to time it correctly. This tricks phone into starting up. Hope this works for you.

Phone will not boot past samsung logo.

Hi everyone,
As the title says, my phone simply will not boot past the samsung logo. I insert the battery, a few seconds later there is a vibration. Then the samsung logo appears, and it shuts down. It does not reboot itself; it just suddenly dies. After it the shutdown, all buttons are unresponsive; holding the power button will do nothing.
I have tried plugging in the charger both with and without the battery inside the phone. When I plug in the charger, the red LED that indicates that it is charging turns on. After a few seconds it vibrates, then almost immediately the red LED light flickers off, and everything is just as unresponsive as before. Leaving the charger inside will yield no results or change.
I have tried to turn my phone on with the battery and charger plug into the phone with a few variations. First, charger first, then battery. The battery is inserted within a second or two of plugging in the charger. The red LED light appears, then the light turns off right before the vibration. The screen shows the battery logo that indicates the phone is charging. This image appears for a few seconds, then it becomes unresponsive as before. Second, battery first, then charger. There are two more variations for this. One is battery, then plugging in the charger right after the battery is put in (before the vibration is felt). After the vibration, the battery logo appears for a few seconds before it shuts down and becomes unresponsive again. The second variation is: battery first, then vibration, then right after the charger. Same result as before.
I have also tried to remove both sim card and sd card. No avail.
I have tried to boot it into recovery mode, as well as download mode. Nevertheless, the phone will shut down before getting into any menus.
I have tried to tap the power button multiple times in case the power button and home button were stuck or jammed. However, I doubt this is the problem.
My computer will not recognize my phone, since I cannot boot it past the samsung logo.
I have tried using different batteries, same issue.
I am aware that a factory reset may be an option that I may have to take, but I have some important data on my phone that is not backed up, and I would very much prefer not to lose it all. I would appreciate any insight on how to fix my problem.
Thanks!
Mine was doing this for a bit until I realized my power button was stuck. The button seemed to press fine and all and looked fine physically, but the contact was somehow stuck. Take apart the phone, direct some compressed air into it using the little 'straw' for the nozzle to focus it... Also try pressing the button a bunch of times hard, etc. And see if that helps.

Fixed it! Opened it up, jiggled around with the power button stuff. I had no idea what I was doing. I blew, with my mouth, really hard on it. Now it works. laaaaaaaaaaaaaaaaaaaaawwwwwwwwwll
You helped! Thankyou
Now would be a good time to backup that important data. A lot of the time, that's is just a temporary fix and it may happen again.

GNexus wont turn on & I cant reboot :(

3 days ago on my b-day I charge my phone only to power it on and have it immediately shut off on me. I plug it into charger and it was still fully charged so i turn on agian and it does the same thing it will just immediately turn off on me. Now its gotten to the point where when i try to power it on the word google pops up and it brightens after abotu 3 seconds then phone turns off and continue to charge. The phone battery indicates it is fully charged however it wont turn on. May i remind you my volume down button does not work so i can not Volume keys and Power button reboot. Plz help
I wonder if the hardware has broken somehow? If just the power button broke, this post says to remove the battery, plug phone into computer, then insert battery: http://forum.xda-developers.com/gal...rnative-to-t1731128/post65166854#post65166854
If only the software has broken somehow, maybe you can flash a new ROM from the beginning using one of the nexus toolkit apps which automate everything for you.

My LG G3 wont turn on

LG G3 D855 (rooted, installed twrp recovery, was using Fulmics rom)
While i was normally speaking on phone it suddenly turns off. It wont turn back on, only LG logo shows and after that it just stops (black screen, wont recognize charger). I cannot access to twrp recovery because phone turns of before i could get to the recovery.
I have tried to pull out battery and back in and noting happens all the same. Also i have tried to charge phone after putting battery back in the phone, but it charges for few seconds and again same no red light, black screen and wont turn on.
I have another LG G3 and i have tried another battery but noting it is same. Battery form the phone that dont work, work in another LG G3, so it is not battery problem.
I have tried to connect phone to PC and i can hear sound of plugged device, but on the phone is all black no sign of turning on, so i can not access to my files on phone.

And also tried tutorials like this :
1. Take out the battery
2. WITH THE BATTERY OUT OF THE PHONE AND NOT PLUGGED IN, press and hold the power button for about 15 seconds.
What this does is it drains all the power stored in the phone and takes the power source away so the phone can fully reboot and refresh the power cycle.
3. Replace he battery and plug in the phone.

If you could help me I would appreciate it
Uh I almost forgot I have noticed that when I turn on other phone with battery and than fast put that battery in this one it stays on logo just a little bit more.

HTC 10 Unresponsive & Can't Restart But Alive

I hope I'm posting this in the right place but I'm desperate for help.
My phone, HTC 10, froze and then the screen turned off while I was taking a picture.
The charge should have been around 80%.
Symptoms:
The screen is unresponsive.
Couldn't get the home button/finger print sensor to turn the screen on.
Couldn't get the power button to turn the screen on.
A call to my phone could not reach my number as well.
When plugged in to a wall charger or laptop no indicator light turns on.
When connected to a laptop, the laptop makes that connection noise and a long name with QualComm in it shows up.
Tried Power Button + Volume Up for 10 seconds but didn't get any result.
Side note:
The power button was a little faulty before as well.
You have to squeeze it a certain way to make it work.
I need to somehow restart my phone. Any ideas?

Try to clean all buttons really well, if it keeps failing to boot and the phone is still recognized as Qualcomm it's probably bricked.
Simple explanation of the word bricked :
When the phone doesn't boot, when you can't access the bootloader, download mode or recovery it's bricked!

Strange turn of events: I plugged the phone to my laptop because I read somewhere that it drains the battery. Just for the kicks, after a few hours, I unplugged and re-plugged my phone. Suddenly, there was light. The battery light came back. I immediately switched to the wall charger and once I did that the battery icon appeared showing 1%. Now, it's peacefully charging away. Will see if it actually turns on later on once it's charged about half an hour.

Stuck in low battery boot loop

Hello, Huawei gadget friends.
My watch started to go in to a "low power boot loop" a week ago so I left it alone hoping a full drain would restore it back to working condition, but alas not.
So now this is the situation:
1) press button, nothing happens
2) connect to power shows the charging icon (white battery with power sign) and then after a few mins commences a boot loop as follows
3) from the charging icon, then gives the "Device software can't be checked for corruption..." message
4) followed by the red Huawei logo, then a single vibrate and then back to step 3 above
5) removing the watch from the charger stops the boot loop but then shows the low battery icon (white battery with one bar).
In one or two occasions, I saw it boot up to the colorful spinning 4 android wear logo, but did not complete (did not show "Android Wear" before rebooting again.
I have tried getting it to recovery mode screen or fastboot but without success -- I keep getting the second buzz without fail.
When the beta of 1.5 came out, I tried it, but since then, have wiped my mac and don't have the adb/fastboot software anymore. From reading the forums, there is now some new software called TWRP. Please advise what I can do.
Would I be right to suspect that it is some battery problem? Is it beyond help? :crying:
Thanks in advance!
MMM
Edit: I have also left it on for several hours charging (and rebooting constantly), thinking that perhaps it is just low battery -- but no success.
I'm experiencing the same problem, i turned it off yesterday at 17% and connected to the pc this morning to charge. I immediately noticed that it started looping with the white icon and it doesn't turn on, nor boots into download mode.
Have you found any way to restore it?
Mine doesn't show the red HW logo, charged for some hours and nothing.
I noticed that the pc see that there's something connected, but keeps saying "USB not recognized". I don't know what to do, i may open up and disconnect the battery
EDIT: SOLVED, it was just the cable that broke somehow. I soldered a new cable to the circular base but that didn't work, but as soon as i received this i connected to the pc and started pressing the button randomly till it showed the battery logo and started charging
I got this when I plugged it into my laptop. Plugging it into a dedicated USB charger solved my problem - I suspect the power rating on the USB socket wasn't high enough to charge effectively or that the USB socket is faulty in some other way. From what I understand, not all USB sockets are equal in that some are suitable for high-drain devices, some not so much. So trying another USB port on your computer may also help (Unfortunately at the time I was backing up to an external HDD on the other USB so that option wasn't open to me).
guyz, i have tried my method it actually worked on Xperia X Perfomance
When it goes to Bootloop for Drained battery, i just plug the cable and perform activity block method By pressing and holing power and both volume up and down and when it hits the 1st viberation i just simply release the key. (remember dont hold it too much long after 1st single viberation just release the keys ) and your phone will go to block activity mode. charging light will change it colors from red to blue.. after 2 minutes just press power button then you ll get another viberation and your phone will be seen as charged 2% and then it will be normal again...
i think it happens when battery drained and phone is unexpectedly trying to go boot in first place.
thank you
