Does the order in which you plug back in the battery matter? I plugged the battery cable in, then the interconnect cable. I broke the digitizer during the replacement, so I have no way of seeing if it actually boots. When I hold the power button to turn it on, it vibrates a little, so I know it is turning on, but if I wait 5 seconds and try it again, it seems to boot again. Does this mean the phone can't boot anymore? I have also tried plugging in a usb c to hdmi adapter to view the screen on a monitor, but no luck.
I had the same problem, I endup buying up new screen which didn't fix the issue. I had bad screen and mainboard. you can take it to store and have him plugged the good screen to see if its booting up, if its then you can buy the screen if its not then its not worth it to get both replaced

So, i hard reset my phone, it was rooted and had the very first version of cwm. I powered it off and had it in the box for 2 weeks now. I went to power it on today, and no go. So I plugged in the the charger and the battery popped on then off real quick on the screen. Screen is black with a faint blue led indicator blinking every 2/5 seconds or so. Not powering on, not able to enter download mode, not able to boot into recovery. What is going on lol, never experienced this
Leave it off and charge it for a bit? Maybe it's bricked?
May have a brick, but I did nothing wrong. Have no idea what went wrong
1, leave it on the charger (try different usb cable or charger maybe)
2. remove battery for a few minutes
3. try again
4. if all else fails get a jig (<5$ or build one instructions around here somewhere but is just 300kohm resistor between pins 4&5)
my money is on a bad cable or charger
but it's possible you have a hardware failure of some sort.
I have used 2 usb cables and 2 wall adapters. Thing with a jig is, you have to power the phone on. I can't do that
I've been going nuts with this problem, that if the phone is being charged with usb cable plugged in, when I press "Power off" the phone will shut down and automatically restarts itself.
If I unplug the cable the phone can power off fine, but when it's in power off state, as soon as I plug in the cable, it starts itself automatically just as if I pressed and held the power button which I didn't.
What's going on?????????? Please help.
Clarify: it's not that the screen turns on, it's the phone actually turns on / boots / starts.
EDIT:
Did a little research, my problem is the same as here:
http://forum.xda-developers.com/showthread.php?t=1209918

I noticed with mine, the only time it started up automatically was when I didn't have the USB cable plugged in fully to the wall charger.
I think that the phone can somehow detect either resistance or capacitance changes in the USB connection and turns on under certain circumstances, while it is supposed to stay off if the resistance / capacitance values are "normal".
it's normal for the screen to turn ON when you plug in the USB cable
it's NOT normal for the Phone to turn ON from OFF when you plug in the USB cable
the normal behaviour for when the Phone is completely OFF when you plug in the USB cable it should just show you the green battery meter charging

The phone turns on.
maybe it's a defective unit?
have you tried going back to stock?

I doubt it's a defective unit because it used to be fine. Just happened yesterday.
Everything is stock right now.
try a different charger/cable. if it still happens return it.
I had this problem after wiping my battery status and draining it all the way down. After charging over night, I then ran battery calibrator the next day and when i ran it all the way down again and plugged it in the problem was solved. Hasnt happened since (since 2 days ago when this happened anyway).
very interesting
Mine turns on when I plug in a usb cable while the phone is turned off following a battery stuck at 100% condition. In other words, if my phone is stuck at 100% (usually every time after charging), and I turn the phone off, and then plug in the usb cable, the phone will turn on by itself. But if my phone is not stuck at 100%, and I turn the phone off and then plug in the cable, I get the green battery.
Hi everyone,
Replaced the screen on my LG G3, and now it won't turn on. Before I removed the screen, the battery was completely dead and I let it sit for a week and a half completely dead. I tested the battery with a multimeter and it shows about 2.7V across the + and -. But, the other terminals, it shows between 2.2V and 2.5V. When I plug the phone in now, there are no LED lit or anything. I tried just plugging the motherboard into a wall charger and even still, no LED lights. Oddly enough, though, I plugged the old screen back in(As well as the phone charger) and the backlight came on randomly for a second when I pressed the power button. The backlight wouldn't come back on again until i removed the power from the wall and the battery. It also helped if i unplugged and replugged the screen. It was very random. I am thinking that the motherboard grounds to the frame or something and I missed something on the install. Any thoughts? Thanks
Having an odd issue with my wife's 5x (completely stock).
She brought it to me this morning - the phone wouldn't boot. She didn't think the batter was dead, but she wasn't sure.
I hooked it up to charge, left it for an hour. I notice now the charging indicator comes on screen for about 2 seconds, goes away, then returns a few seconds later, and repeats this.
If I try to boot it, I get the Google logo for a few seconds, then it shuts off.
I can hold volume down and power and get to fastboot, but I'm not sure what to do from here. If I choose recovery, I again get the Google logo for a second, then it shuts down.
Is it the battery? Something else? Any help is appreciated.
EDIT: I want to add, when I unplug it from a charger, I can't do anything - no even partial boot. I just don't think it's charging when it's on the charger because of the battery icon showing and disappearing in cycle. I suspect this is a power/battery issue but don't know what to do.
Do you have a spare USB C cable to try charging it at all?
It could be the cable so its never charging enough to stay on/boot. I assume all your chargers are the proper LG ones and no dodgy USB cable might have fried the phone in any way?
Otherwise contact whoever you need to for warranty repairs by the sound of it.
I think this is 5X problem , LG should take care of it .
This is not charger problem or anything else .
If you can go to download mode it should be fine .
Your phone just turns off or it reboots? If it's rebooting, same issue as mine and another user's phone.
It's probably the power button issue that's somehow always being pressed, making the phone reboots over and over. It happened a lot with nexus 5. I sent my phone to LG for a repair.
Hi,
I just installed a new battery into my OnePlus 3, because the old one was starting to bulge and push against the screen.
After installing the new battery and attempting to boot with the charger plugged in, the phone won't boot past the 1+ screen.
It buzzes, shows the 1+ screen for a while and then goes dark and buzzes again etc. If I pull out the charger cable it goes dark instantly.
If I hold down the volume down button and the power button for 30sec it boots and shows a warning screen saying "Battery too low. Charge for a while before powering on". However, this screen only shows for a split second before going dark again.
I added a photo of the same screen on a different phone that I found online as the screen really disappears within a few milliseconds on my phone:

Does anyone know what this means? Is the new battery faulty and should I return it? Is there something I should do to reset something? Can it be that it is simply not properly connected?
Any help is welcome! Thanks
you should leave the phone and let it charge until 100%

I let it charge all night, but obviously it is not charging...
is there anything important on the device
Just opened up my phone to put the old battery back in and that's when I saw that the connector had gotten loose. :silly:
There were some small pieces of tape on the original battery's connector that are supposed to hold it in place, so I fabricated my own out of Scotch. Hopefully that will hold the connector in place.
ok get back to me because i want to know if you have solved this
