LG K500 no boot only battery logo and a red ? - General Questions and Answers

Hi,
We gave to me a LG K500 not working to see what I can do with it.
When I turn on, I only have a battery logo with a bllinking red question mark...
I tried to plug in but always this battery logo, however the charger and the phone are heating up, so it seems to charge...
I tried to plug it on my computer but nothing is detected...
Do you know something about this issue and maybe a way to solve it ?
Thanks !!

Almost the same problem here after I installed an update (don't know which one). I get the HTC Quietly Brilliant and then it reboots until it runs out of power. Hooking it up to a computer, wall charger (tried two different ones) shows the red LED charging light for a while, and then it reboots. It seems like my battery just wont charge, so I can't reset or flash back original ROM. It just shuts off after a couple of seconds. I can go into recovery if plugged to a computer for as long as I like, but as soon as I try to flash, it turns off and goes into reboot loop.

Phone won't turn ON or Charge.

Hey there , i came to you because i think my phone done a short circuit, it was ON and pluged in an inactive USB port on my PC which i've plugged internaly just after.
Then i noticed that the low battery LED on the OnePlus doesn't blink anymore. First of all i thought about a complete discharge. But no charging LED. I've plugged the phone on the power adapter : No LED. This is when i started to freak out.
I've took appart the phone, removed the battery, mesured the voltage : 3.77 Volts. The battery is normaly 4.35 Volts.
Is it a big gap even if there is always a tolerance ?
Is my battery is dead ? Or something shorten the motherboard ?
I don't want to buy a new battery if this won't solve the issue, and i have no schematics to do a continious testing with my multimeter on the motherboard..
Any help is welcommed. Thanks.
I think you were too quick to take phone apart, you should have been keep the phone connected to charger for atleast 6 hours before taking it apart ..

Connect your OPO to Wall Charger, Charge it for about 10min or so. Press n Hold Power Button for at least 1min.
If nothing fancy happened to your phone than it should boot from dead. If not than think further.
BTW When you connect it to your pc, how's your pc recognize your device as?
Any QHSUSB_BULK 9006 Or 9008 error? If not than Its not Bricked yet. Just try to charge for 10min and check.

Do you have OnePlus drivers installed? Or Have you installed them previously?
There's no way Phone could go dead without any prior sign. I mean there must have been something happened to it before it gone dead brick!
What was last state when you saw it working beforeot went blank?

Of course my drivers are installed.... but the phone don't do anything when plugged, no charging LED, no reaction when i push the power button
Before he goes "dead" he has low battery.

Charging LED will only lit up while device is ON. If device was completely functional before it died, than I'm assuming it as Battery issues.
Did it ever got warm or hot near battery area? Since you've already took it apart to check voltages,so you know it better which area I'm talking about.
Most likely it could be Battery. If not anything major.

Okay so i got the phone to boot up. plugged it into usb : Phone don't got recognized. battery charging logo in status bar
Plugged to power adapter : Battery charging logo on status bar.
I noticed that the charge is incredibly slow. then i goes in parameters -> battery to check battery mode and stuff.
underneth the graph it says : 2% Not charging. But i got the logo on the status bar... ?
So here is a recap of the issues i got : Battery not charging, and discharging fast.
Not recognized by USB
No rear faced camera and flashlight.

If your device booted up, Can you post some screenshots of it? I just need to see whether a Port got damaged or something else.
BTW Which ROM you're ON? Have you ROOTED your OnePlus One in the past? Or Its Still Stock?

hi, how did you get it to boot up? are you running the device directly from USB power? or is it running on battery?
Hold volume up, nothing else and connect it to your PC. After that check device manager and find "QHSUSB_Bulk. If you can find that one, send me a PM.

Ok after seeing that the phone was low battery i disarmed it and charged the battery with two cables from and or usb i peeld just for this situation. After leaving it for like two hours i put the battery again and was stuckd into the Motorola logo... nothing hard, but what is pissing me off is that now i CAN'T BE ABLE TO BOOT INTO FASTBOOT and it's just stuck booting o trying to (when i connected the battery the phone turned itself on). Now i don't know what to do, i'm desperated, please, help me

I have exactly the same problem. My moto g doesn't stop trying to start uo even if i am not pressing the power button. When I connect it to the charguer screen turns on and says o% battery, then it tries to turn on itself. Have you solved this problem???
@duvaldavidr @jorgearnaiz998 Any of you had any luck?

s6 dead and not charging, screen black....any chance to recover it?

Hello all,
on friday night my Samsung S6 Duos just died and it seems I'm not able to revive it...
it was running out of charge (was at 5-10% battery)...then suddenly the screen went black and the red led was blinking every second or so...
I thought it was just hung like it happened sometimes, so I tried to reset it pressing vol down+power or home+power buttons, but nothing happened....screen still black and red led flashing....
so I thought it was some kind of battery problem...tried to recharge but nothing changed...no battery icon on screen and red led flashing (not solid as when it is charging...)...
so, since battery cannot be pulled off I waited till complete discharge hoping that would reset it....waited till led was not flashing anymore, then I tried to recharge but nothing is happening....led not becoming red as when it's charing, nor display is showing battery charging....
actually nothing happens, I've tried to leave it charging several hours, both with power cord and with wireless charget, but it just doesn't charge and doesn't power up anymore...also tried to connect it to PC but nothing happens...
do you think that opening it and trying to disconnect and reconnect battery could solve? or maybe changing battery?
or is it probably a fault in the motherboard?
I just want to recover photos and other data saved on its memory but if it's motherborard issue I think everything's lost...right? 'cause memory chips are on it...or am I wrong?
thanks for any hints or suggestions on how to recover if possible...
