I have a l9. It turned off by itself and won't turn back on or recognize a charger. Lg reps were no help. What can I do to get my phone working again?

Do you know why it turned off by itself? Because of out of battery or just a sudden off? Can it enter s/w mode?(Remove the battery. Hold volume up and plug in usb.)

Battery is ok, have even tried a new battery. No idea why it turned off, I was texting when it happened. First 2 times I was able to get it to come back on.

I've read about problems like this - you can try flashing it with kdz, but if it doesn't help - go to the service centre

Tried that with no results.

I have charging problems too.. My Device (without internet access, wlan, and so on) is after 5 hours empty... When its under 30% and I turn it off it won't turn on.
Only when I plug it on the charger.. I get after 10 minutes a live sign..

have you just tried to pull your battery for a min or two. Have you tried to hold the volume + - power?
have you try to charge your phone for 10 min and hold power button for longer than 10 sec to turn it on ? , np

[Q] Can't turn on Galaxy Ace

I MOVED THIS TO A MORE SUITABLE AREA: http://forum.xda-developers.com/showthread.php?p=19126103#post19126103
After rooting and getting my unlock pin, I uninstalled some pre installed apps.
When I try to turn on my phone - unplugged from any charger, it shows the battery empty symbol (sometimes it just does nothing) and wont let me turn it on. BUT! when I plug it into the charger it shows the true charge of the battery (100% at the moment) and I can turn it on.
Another thing I've noticed is that holding the buttons for download mode puts me in RAMDump Mode, and Recovery mode is now a different button combination.
I have to put it in download mode Via ADB commands.
So my problem is I cant turn my device on unless its plugged in - but once it's on, it no longer needs to be in the charger.
I have unrooted it and flashed the firmware via ODIN several times now which has not helped.
Please give ANY suggestions!
try factory reseting

I selected the option for that on the phone, but it doesn't actually reset to factory state.
Which is why I've tried to flash it back using ODIN, but that still leaves the same issue behind.
Thanks for the suggestion though.
Please use the Q&A Forum for questions Thanks

Flash a new Rom? I think you have messed up with system files.
Accidentally sent from my Google Nexus S using XDA Premium
Thanks for the replies.
I have fixed it.
I drained the battery completely, and let it turn itself off. I then charged it up again and this seems to have fixed it.
I can now turn it on without it being plugged into the charger.

Lumia after 0% battery dead

I got this problem. My battery gone on 0% and phone turns off normally.
After that no on.
When connected on charger it come NOKIA logo with vibrate and come windows phone logo and than shut down and repeat.
I tried all solutions over net and not helped me.
What to do?
please anyone? I dont have warranty any more....
That depends... What was the last thing you did on your phone?
Did you try unlocking the bootloader? If so, did you format the disk when prompted? Never, is anyone supposed to format it. If you chose 'Cancel' then theres hope.
I would suggest trying NSS & unlock it...

Leave it on the charger for several hours. If the battery is completely empty it can take quite a while until it is able to be restarted.
8 hours was on charger and nothing.
When connect to charger bootlop is whole time.

Did you update your phone to Tango in the past day or so?
yes few days ago.

I had a similar problem after I updated my phone, the battery just wouldn't charge up. I was able to flash the older firmware back on to the phone and it would charge the battery but as soon as I put ANY of the tango firmware's on the phone the battery would stop charging.

When you plug in the charger you're phone is turning on but it keeps looping through the boot sequence as the screen eats up more power than it get's. Try using a wall charger to charge your phone, once the screen come on turn it off. You should be able to put enough power about 2% which would be enough to try your phone on long enough to flash it. First try to see if you can get the phone to boot up from a wall charger.
When is wall charger it come to windows logo and turn off.

Can you turn the screen off before it gets to the Windows logo?
only turn off phone if plug off charger.

Unfortunatly if you can't get the phone to boot up at all then you won't be able to flash on the firmware
The only solution you have is to send it back to Nokia. I dropped my phone in and was given a new phone which now works perfectly
I dont have warranty soo I gave to local service shop....
They said some problem with battery and will tell em tomorow how much will cost.

HTC Desire X won't turn on

Hallo
My uncle has an Desire X and since a few days ago it suddenly stopped working. He turned off the phone and now it won't turn on anymore. He gave it to me so I could try to fix it.
Things I've tried:
Charged it for an hour. (LED turns on)
Removed the battery for a about ten minutes.
Connected it to the pc. (LED turns on)
Tried turning the phone on connected to the charger without a battery
Tried going into bootloader by pressing volume down+power button
Any other things I can try?
Btw the phone has no warranty and as far I know it hasn't been dropped.

You might have already tried it but what happens if you press and hold the power button for at least 10 seconds?
I held it for for about 30 seconds.
I put in another battery that didn't work either so I'm just going to give up and give it back to my uncle.
Thanks for the reply's!

S6 edge won't turn on, won't respond to anything, but is hot

Hey guys, I just did an update last night, the update was around 330mb, then I drained my phone completely, charged it, then fell asleep, when i woke up, I removed the charger, and the phone won't turn on. Tried pressing all 4 buttons, tried going to recovery, safe mode, and every other combination of buttons, but the phone won't turn on or even go to the samsung logo or blink or anything. Even if I connect it to the laptop, nothing happens. Screen is off, but even when it is not attached to anything, the phone is hot. Which means it is technically on? I'm thinking of letting it drain til it runs out of battery then recharge it?
Anyone? I tried all combinations, nothing makes it work, not even make the led blink, no vibration. Also, i tried charging it for a few hours, it just gets warm but no charging icon or anything.
Does it get recognized in Odin? You may be able to fix it by reflashing stock

I'll try later. I still don't have odin. But that would probably be my last resort. I don't want to lose all my stuff.
Bu the way, my phone is all stock, no root.
OK so I kept the phone charging and now I tried turning it on, nothing, but the blue LED came on.
Now the blue light is off again.
Trya computer to see if it is recognized. If so, just copy your entire folder from your phone, try to Odin, then if successful copy over your files

I have never connected it to my laptop before so it may not have the drivers? But the laptop does not read it. Kies does not see it. Now i borrowed a friend's wireless charger but he said he thinks something is wrong with this charger cus it charges, now i put the phone on top, the charger shows a blue light but phone is not responding to it.

Tried that. It doesn't work. Oh and now that i tried charging with a wireless charger and still same thing, i guess i can safely conclude it's not the port. Maybe i need to try a charger with higher amps to try and wake it up?
Is it possible that the update does not allow the use of chargers that or not originally for the unit? And i used a samsung slow charger that night after the update, so the whole night the phone tried blocking the current and ended up frying the diode/resistor? Or maybe since i drained it to 0% it went to deep deep sleep?

No any charger should work fine it doesn't have to be official samsung charger. Do the touch key lights come on at all? Have you tried to connect to odin?

Open odin, plug in phone and a box on odin will go blue and will say com 3 or something. If that doesn't work try smart switch

I think it didn't show anything when i did. I will check again later.
Is it possible that after the update, when i charged it didn't accept the charger so the battery got drained fully and now it can't charge? A technician said the battery needs to be "shocked" but they don't have the equipment to take off the back to get to the battery. Any thoughts on that?
Would it help if i charge it using a 3.4A charger for a few hours? Maybe that will wake up the battery? Technicians say that because it got to 0% it might have been fully drained and unable to recharge, what they usually do is direct charge a battery but in the case of the s6 edge it's not that easy to do since you have to take it apart...

This is possible, I had the same issue with an iPhone and I had to open the case and charge it externally
Anyone have any other suggestions? I would probably bring it to the service center on monday, but I think if i have it serviced, they will just forward it to another city since I don't think they do repairs in mine.

Official samsung charger should be enough to get it charging and working. Service centre sounds best option
