Hi all,
I have a LG G2 from AT&T. Had it for about 1.5 years now. No issues until now.
I was just watching some YouTube videos and the phone suddenly shut off. I tried the power button and it won't turn on.
I plugged the G2 in to a power outlet, but it was just stuck on the "LG" screen. I unplugged the cable, and now, even when I plug in the cable, the phone won't turn on.
Can someone please help me? Thanks in advance to anyone who can.
I believe it's due to the motherboard, but I'm not sure.
Really would like someone's help!
Bumping. Really need help with this.
Can you put it in download mode?
Plug in your usb cable from pc holding vol down button, if nothing happens, try at the service centre because it can be hardware related.
The phone doesn't do anything when connected to the laptop with the button held down. :/

Hi all,
I got a Samsung Galaxy S (i9000) from a friend who wanted to toss it away since he says it is broken.
I want to see if it is or not.
When I try to turn it on, complely nothing happens. When I put the charger in (or the USB cable fot that matter) a battery sign appears with 5 dots under it which move from left to right. When I try to switch the phone on nothing happens
When I wait a while, the screen goes black. When I try to switch on, nothing happens.
When I push the home button, the green charging battery appears again and the back an menu button light up.
A factory reset is not working at all. Can it be that the power button is broken??
Any help would be greatly appreciated!
Regards,
Vincent
Fixed it!
Hi,
I was able to fix it.
Thanks to this sticky: http://forum.xda-developers.com/showthread.php?t=1134975
This is what happened:
I tried just about anything, nothing worked. Then I saw a reply in this thread someone mentioning you should plug in the usb cable, push both volume keys and then maybe it could work. But of course, mine didn't.
Then I started experimenting, what did work was this
- take out battery
- connect usb cable to laptop
- push volume down + home simultaniously and then put battery in
Now i got into download mode (yellow robot and triangle + warning not to turn off target) and with Odin I was able to start the phone.
I then found out that the power button was indeed broken!
Phone works like a charm. Only thing is when I have a dead battery that I have to use Odin to start the phone. I will seek for a way to fix the defective power button.
Hopefully it will help other people with this problem!
BTW, thanks all for all the help
Was plugging in my G2 to charge it and suddenly it had this screen. "Firmware Update. Do not unplug the USB connection until the process is complete."
How do I exit safely? Will I corrupt any data or damage anything? I was only plugging in my phone to a wall socket, so I don't know why there would be such a screen. Help anyone? >.<
Someone knows how I can exit safely? >< Please?
That sounds like its in download mode, which you get to by turning off the phone, then plugging in a usb cable while holding vol up. I always assumed the usb cable needed to be connected to a computer for that to happen, but maybe it works if it just senses power.
Anyway, if the bar isn't going anywhere (and it shouldn't be since its not connected to anything feeding it data) then you should be okay unplugging it and turning the phone off, then back on.
Edit: Just tried it with my phone - turned off, then connected USB cable/wall charger while holding vol up and sure enough it went into download mode. I unplugged the cable, then held the power button until the phone restarted. Booted as normal.
My Lg ls740 prompted me to do a system update 3days ago and has not came back om since. It just keeps flashing from LG logo and the android man...i have tried taking battery out...factory reset...and everything above . Can anyone help?!?!
My LG G2 (rooted with AOKP ROM a month ago) just got bricked about an hour ago. It was completely random too, I had it playing music via bluetooth in my pocket and all of a sudden the music stopped and when I took my phone out of my pocket, it was unresponsive to any button pushing. I plugged it in to my computer to see if I could debug it on there since the screen was completely black no matter what I did (long-pressed the power button and tried hard reset but still black screen). So when I plugged it into my computer, windows said "USB device not recognized" so I can't even do anything with it. I have no idea what to do and am in need of some help . I tried to include all the relevant information and if I missed anything, just ask. Thank you in advance for any advice you guys can give me.
Plug it into a charger and try different button combos, holding them for up to 30 seconds
power+up.. etc
Can you go into download mode ? (while powered off. press volume up and insert usb cable)
Hey everyone,
I don't know what happened wrong with my interaction with AQUOS, but the phone appears to be bricked.
Here's what happened.
Bought my phone from Boost, successfully switched carrier to Ting
Have been using the phone for more than a month without any problems at all
Yesterday, I left the phone without charging and it fully discharged
I plugged it to charge and came back to turn it on after a few hours later. This is when I noticed it wouldn't turn on.
I tried a couple things: holding the power button for a long time, and a hard reset (volume down button + power button). But the results were the same.
The screen doesn't turn on. While holding the power button or power + volume button, the only feedback from the phone is a series of prolonged vibrations (~10 seconds) separated by a brief pause (~1 second).
Have anyone experienced this problem?
Any advice/insight into this problem would be greatly appreciated.
I've had similiar issues with tablets where it completely drained and wouldn't charge via USB. At most it'd just give off a single vibrate and then die before even flicking on the screen. Try this, plug a USB cable in for a full 24hours before you hit the power button. Then give it a try. If it pops on to the screen where its charging after that let it get a full charge before fully powering on. Hope this helps and also hope its not due to the switch to ting.
Best of luck
PHONE OFF
This could be due to a bad usb connection. some usb when broke will actually discharge your phone or tablet so try to use a different usb. PLZ POST BACK IF THAT DIDNT WORK I HAVE MORE SOLUTIONS
Hello All,
Yesterday I dropped my phone and the power button got stuck. I opened the phone with my tools and was able to fix the button. I didn't power it off, I didn't think it was needed since the button itself has nothing to do with the electronics inside. While I was closing its back It suddenly turned off. I was very gentle, didn't do any fast or unsafe moves. Since then the phone shows no sign of life. I plugged the phone the my pc but there wasn't any sign of life either. The phone didn't show up on Device Manager or anywhere else. One time, I heard a connection sound but I am not even sure if it was because of the phone since the sound came like 5 minutes after I plugged in the phone.
I already tried pressing all 3 buttons for a long time but it didn't do anything.
So what do you think? What might have caused it? And can you help me?
Thanks
First thing i would do is tear down and disconect/conect the battery flat. After that, hold volume keys while conect to pc usb and see if you can get edl mode. Than flash all that has to be flashed with miflash and edltools.
