First, are you charging your phone via USB or through the wall charger? I have found on some phones if they are completely dead, USB wont charge them at all. So plug it into the wall. When you plug it into the wall do you get the Charge animation? Let it charge for awhile before attempting anything else, i would say at least 45 mins.
If you let it charge and it still wont turn on, you need to attempt to get into download mode. First, pull the battery and sim and let the phone sit for about 5 minutes just to be safe. Reinstall battery and DO NOT push the power button. Instead hold the Vol + and insert your USB cable that should be plugged into the computer as well. The good news is if you can get download mode, i think you can pretty much always save this phone. You just need to refer to one of the threads that guide you through it.
moved to general
not see a battery animation when i plug in the wall charger.
if i connect to computer and push + computer lost a connection to phone and see nothing. when i release botton see a qualcomm modem

I installed the AOSP JELLY BEAN 4.1.1_r1 (http://forum.xda-developers.com/showthread.php?t=1765288) the other day and it was working fine. The problem is, I used it too much and the battery died on me. Fine. So I plugged it in to my pc via usb to charge it up. The Kindle fire boots to the TWRP triangle and then instantly shuts off. Well I thought maybe the battery is just really drained so I left it plugged in and went to work. Got home and it was still doing the same thing; boots to the TWRP triangle and then instantly shoots off and repeats. I unplugged the usb and tried using the outlet charger; same thing. Disconnected and tried to turn it on and nothing happens.
Figured I maybe bricked it somehow (even though i didnt update, delete, wipe anything). So I tried using the unbrick command lines...nothing. Tried the KFU cant find my device since it shuts off every 2secs.
I cannot figure out whats going on. Any help is appreciated. Thanks
Plug it into the charger and hold down the power button until it shuts off. Then wait for a 2-4 and check back on it.
Once it boots back normally make sure to update FFF and TWRP.
That didn't work. I plugged it in with the ac adapter and it wouldn't allow me to turn it off (i plugged it in then tried to turn it off). I let it sit for 8hrs and still boots up to the TWRP logo and instantly turns off and wont even turn on without it being plugged in. Thanks
Hold the power button down for 1 min it should shut off
it still does not work
Please post here some detailed instructions to turn on this device.
I'm tired of holding on and buttons in different combinations.
Sorry for bad English
If you have fff 1.4 a there really is no magic combination just simply power it off and plug it in via usb to your computer. If you do not have fff 1.4a then look here http://forum.xda-developers.com/showthread.php?t=1623244
Did u leave it to charge overnight.. cos i also had the same problem, which i primarily due to low battery charge..

HI guys. I need your help for my wife's S4 mini.
My wife was taking some photos (approx 40) and the battery was at 80%. She put the hpone in her pocket and when she took it out 30 min later to check the time, the phone was dead......
Power button didn't respond. took the battery out and back in, nothing. removed the sd card, nothing. removed the sim card, nothing. (checked the sim card in another phone and works ok)
when i charge it there is no battery image in the screen as described in the manual.
While charging, if i long press the power button there is a short vibration, but nothing more happens.
Connected the phone with my laptop. i got a msg that there was a software installation (like when you connect a new flash drive), but i can't "see" not even the sd card.
At this time, there is a vibration in the phone and sound from the laptop if i long press the power button of the phone or i remove the usb cable.
Any ideas guys?
i will take the phone to service centre, but i really need these photos today....
Thanks in advance guys....
Try another battery

If not battery it might just be your charger or usb cable. Try another. Allow some time for it to charge before switching on.
Sounds like it is getting some power from your PC but you won't be able to "see" anything unless you have the right drivers installed (probably what your "software" message was). (if drivers installed but nothing is happening reboot )
Hello, XDA, Good morning.
So i was using an LG G3 D850 as an access point for a hot spot while my internet was down for a bit, So i connected my PC to my phones WiFi Hot-spot right? K.
Now I had the phone running like this for quite some time, 2-4 hours roughly. During this time I must have used about 4-5 gigs of data on my phone (don't care about the data use :laugh: ) and nearing the end of my abuse on the phones internet use I noticed that the screen doesn't want to turn on, but the phone is still on AND routing the access point still.
Fine fine, so When i decided to wrap it up and shut er' down, i powered the phone off. Attempt to reboot the phone was laggy at best and lucky to actually reboot the phone a couple times in this state. I powered down after failing to boot up a few times pulled the battery then plugged USB in and I Got the normal screen that you would get (can't remember what it looked like) if you plugged into the USB w/o a battery in. Then after the standard battery failed to operate correctly I stupidly tried a different battery, which was 2,600 MAH / 3.8 V Li-ion battery / 9.88 Wh SAMSUNG battery, I know.... stupid.... ( LG battery : 3,000mAh / 3.8v Li-ion battery / 11.4Wh
Now after All this battery sh*t, the phone did boot up once or twice with the above battery, but that was it. Now when I plug USB into phone w/o the battery in I get the triangle with a question mark and a picture of a cell phone and USB cable going into it. Thats the only screen that shows up, except for the green/red/blue blinking notification light at the top left corner! PHONE IS RECOGNIZED in DEVICE MANAGER and ONLY when I power down , cable in PC , hold volume + , insert cable , hold Volume + for about 5-8 seconds til I hear computer sound beep then I let go and I get LGE Android MTP device , LGE Mobile USB Composite Device and LGE Mobile USB Serial Port So i have some connectivity but no screen display unless , plugged in w/o battery. I have tried flashing kdz file for sh*ts and giggles to see if it would do the trick but still the same.
Wheres the veterans at ! Thanks in advance , Cheers!
Forgot to mention , that, Even right now the phone is plugged in blank screen still but being charged and will blink twice every minute or more, green notification light , top left. ***
Actually it blinks automatically or if i press the power button it will blink twice as well. . . What does this mean?!
Is download mode working?

the good news the phone isn't bricked and it can't be unless harware failure, you will need to use the button combo to get into download mode and flash a kdz their are enough threads on how to so I won't write it again

I believe so, There is no display on the phone however, when its plugged into the computer I don't see anything in Device manager except I hear a sound on connection , then when I hit volume + and then insert the USB cable i get MTP driver, Com PORT driver, and CDC driver I believe.

I have flashed a kdz already using LG flash tool 2014 method. But I will try the zip and dll method i guess. If there are other options i would love to know about them.
Refraining from having to short circuit the MOBO and wondering if this problem is as easy as getting a new battery and charger ?
Thanks, Wish i still had my jtag.... zzzzzzzzz

add little more clarity. when you connect to pc does it shows anything in device manager? does it vibrate..
open back cover disconnect battery connector for a while a connect again. you can also try to put it on charge for a while.
Cross-posting this from r/NextbitRobin
So Tuesday night before bed I went to check my phone (which had been on the charger for the last couple hours and so was at >95%) and noticed the volume button was not responding. I figured something buggy was going on, sometimes I need to reboot my phone every couple of days to get it to work properly (especially if it had run down into low power mode before recharging), so after unplugging it from the charger, I held down the power button, selected reboot, and clicked okay. The phone then proceeded to shut down, but not start back up.
When I tried to start it up again by holding the power button, I got no response initially. Then I was able to get it to buzz/vibrate, but the screen never came on.
I tried holding down the Vol- button and the power button together for 20 seconds to force a reset, and it vibrates a couple of times, but nothing happens.
If I plug it into a charger, I don't see any LEDs illuminate, and it just vibrates approximately every 3 seconds (not continuously, it seems to have some semi-random pattern). If I unplug it, the vibrating stops, but I still can't get it to turn on. It does not seem to make a difference if I am using a wall charger or trying to charge it off my laptop.
I have not rooted the phone or installed any custom ROMS, and have had it since I bought it on Amazon in June of 2017.
Any ideas what might be the issue? Any tips for reviving my phone?
This doesn't seem to match anything I have been able to find with some basic google searching.
Edited to add that I also tried removing the sim card and starting it up without one, but that did not appear to make a difference.
Update: I left it plugged into a wall charger for about 18 hrs and when I came back there was no change in behavior.
This many sound repetitive but lets first get the obvious out of the way so that we are sure you tried the most basic things for sure.
Is there an issue with the cable not able to charge the device? Can you try changing the cable?
Power + volume down for 30 secs / 1 minute / few minutes. This usually helps, sometimes more than 30 seconds for some reason. Try doing it while plugged in.
When you connect to the laptop what happens? Does it power on for a minute or vibrate?
Do you have adb installed on your computer? does you device get detected on your laptop?

Tried charging it with both the OEM cable as well as an amazon basics USB-c cable (both of which had been used to charge the phone successfully in the 24 hrs before it went wonky), no noticeable difference in behavior.
Held the power + volume down buttons for 180 seconds, did not boot. Repeated this with it plugged in (wall charger) and it still did not boot.
When I connect it to my laptop, I get the same behavior of vibrating as when plugged into a wall charger, but it does not boot or power on, nor does the laptop detect the phone in any fashion. I do not have adb installed on my laptop.
Anything else I can try, or is the phone a write-off at this point?
First step to solving any device issue is to somehow boot it and get in any mode possible. Since you can't do that I can't think of any other way to get it working.
I'm having the same issue, phone is not giving me any signs of life...frustrated at the moment
It's a total long shot, but try carefully cleaning out your charge port with a needle or a small pin and a little bit of alcohol. I pulled quite a bit of pocket lint out of mine and it works fine now. It didn't look like it was that dirty, but I pulled out a large ball bearing sized amount.
Other than that the only other thing I can think of is that your battery might be shot. It might have been taking enough of a charge to try and turn on, but not enough to do so.
