[Q] Phone won't turn on with battery pulled - Sprint LG Optimus G

Alright so my ls970 doesn't respond at all when it's all connected, but when I pull off the back and pull the the battery off and plug it in, it just shows a flashing red light in the top right. Also I plug it in and it shows the Google logo and then shows a battery with a charging symbol in middle. I tried all button combinations and trying to reset it but it doesn't work. Also when I plug it into the computer, the computer recognizes it and then it loses it and connect again and loses it. Any ideas?

If you already have the back off, pull the battery, try to power on the device with no battery, hold the power button to drain the battery, then put the battery back and try to charge it without attempting to power it on. Let it sit for at least a couple hours, then try to power it on again.
If it is all the way dead and you have the battery out or disconnected, there is always a chance of a brick. Just saying. Keep trying, though.
The other option would be to charge just the battery with some sort of power supply (with the correct voltage/wattage) and put it back in the phone, or get a different, fully charged battery from another device and try it in yours. Or try to find a new battery.

Battery Won't Charge!

I know there are other posts about this but my battery won't charge. I rooted it and it completely died. Now when i plug in the stock charger, it turns on, boots up, then dies, and repeats. I plugged it into my computer, and the orange light is dim. After about 20min, I got a message from fff saying: "Battery is too low to power on, wait a few minutes and try again." or something like that. After that it just stays dim and when i press the power button nothing happens. This has happened to me before, but i rebooted the system(with TWRP) and then i got the same message, but it charged fine. Please help.(BTW i am using it USB right now, because Stock charger still wont charge it.) Please help!!!
EDIT: Right now it goes to the Screen indicating that it needs to be charged and then it continues charging. After awhile, it will turn on to that same screen(charging screen) and i realized the backlight was lit after the indicator turned off and i cannot turn it off!!! Ive done the 20sec. hard reset but still it stays on. Help needed!!!(BTW it is the FFF bootloader i think)

Maybe try booting into twrp and then when its fully charged boot it again to system. Can you boot into twrp or does it instantly just go to that screen again? I dont want to start speculating about the condition of your bootloader or anything else based on the info you have given. All I know for sure is theres an indication that it needs to charge. I would try quicky plugging it into the wall charger from a powered off state. I would hold the power button for 20 seconds to verify that it is indeed powered off. Most of these are likely gestures of futility. I can only say what I would do myself. Lastly I would remove the back and unplug the battery then after 5 mins or so plug it back in or plug it in via usb without the battery in and if it booted correct carefully reconnect the battery but Im not recommending you take this approach. Give it time charging via usb hopefully it will somehow break from this cycle that what the bootloader is supposed to do in the event the battery has been drained to below 4%.
Whether it is stuck like that I cannot tell you.

Help identify problem phone not turning on

I was using the phone when it froze, i tried restarting it nothing happened so i pulled the battery. Now it wont turn on.
When i try to charge the phone, no battery indicator is shown, even the LED does not light up.
The only signs of life is when i connect the phone to the power bank, the power bank shows that phone is attempting to draw electricity when i press the power button
I got the battery checked externally and it came up healthy and 100% charged.
The phone is not detected by the PC, no matter what button configuration I press.
what are my options? Thank you for your time.

Its a hardware problem. Many people have had such issues, take the device to a service center.
I had this problem , here are some problems:
1.battery failure : makes the phone shut down unexcpectedly until it fries the board or emmc.
2. Go to fix centre immediatly , dont wait ,dont do anything at your risk.

Phone just doesnt turn on

So I was at 3 percent and plugged the phone in the car charger. I just texted and the phone got stuck. Waited for it to start being normal again but it didnt. Suddenly it shut down, restarted and got stuck on the LG logo. I waited and waited and finally removed the charger and took out the battery. I then plugged the charger back in but the screen would just not light up. Tried holding the power and volume button key at the same time, but to no avail. Took the battery out and kept the power button pressed and then put the battery back in. Still wouldnt work. I then connected the phone to my laptop and pressed the volume up key to enter into download. Nothing.
What is wrong with my phone? The phone is just DEAD. It doesnt even light up showing that its charging when i put the plug in. What should I do?
The phone is rooted. Its on stock rom btw.

Please do some search and refer to the bootloop thread as there is no need to create new one. since there are many discussions on this topic already. Try freezer or baking method and see if you can at least get it to boot to have your data backed up.

Unplugged phone from computer charging and it stuck on charge screen. Won't boot.

I was charging my phone connected to my laptop, the phone was powered off. I unplugged it and it just stuck like it was still plugged in charging. The charging light is on but trying to rest or boot does nothing. Just makes the charging light turn off for a second then back on.
Is it bricked? What should I do?
UPDATE
I let the battery drain out overnight and plugged it into the wall socket this morning. Now the charge light blinks but no charge icon pops up and it still doesn't power on. When trying to boot it into recovery, the icon pops up again. When I unplug it from charging, the charge light still blinks and the icon stays still. I think it is going to have to be a paperweight.
Anyone ever had this happen?

First, let the phone charge on wall socket for several hours. This is sometimes needed if the battery is allowed to drain to shutoff, and there is unsufficient battery voltage to boot/power-on the phone.
There is no button combo to directly access recovery on this phone, so I think you mean you tried to boot to bootloader (power+vol down). In some conditions like this (battery drained, stuck on boot screen, etc.), you will need to hold button combos for a minute or more before it will reboot. So try to just hold the buttons longer. Also try to do this (hold for a minute+) for power+vol up (this button combo forces a reboot in most situations) or simply just the power button ("regular" power-on).
Power + vol up would have been the best way to force a reboot (works in virtually every condition short of a true brick), rather then let the battery drain to shut-off. Letting the battery drain to shutoff is never a great idea, if it can be avoided, for the reason already mentioned.

Oh man! I was freaking for a while. I tried like everything except holding the buttons down so long. That reset it. It booted. When it booted up I tried to update the with the OTA in settings and it locked again on bootscreen. I did the hard reset again. It didn't update. I want to update it to Android 6.0, but it keeps running into problems some error "unexpected contents on partition - installation aborted." Something like that.
Thinking of trying to flash the OTA or RUU. Do you think that is a good idea?

I did the same a while back. Found my M8 had powered off overnight. Tried the button combos, which didn't seem to work, and thought it was spontaneously bricked. Finally just tried holding power (or maybe power+vol up, don't remember exactly) for a long time, and it finally booted, leading to much relief.

Flash the OTA how?
RUU should be fine, if you version has an RUU.

HTC 10 Unresponsive & Can't Restart But Alive

I hope I'm posting this in the right place but I'm desperate for help.
My phone, HTC 10, froze and then the screen turned off while I was taking a picture.
The charge should have been around 80%.
Symptoms:
The screen is unresponsive.
Couldn't get the home button/finger print sensor to turn the screen on.
Couldn't get the power button to turn the screen on.
A call to my phone could not reach my number as well.
When plugged in to a wall charger or laptop no indicator light turns on.
When connected to a laptop, the laptop makes that connection noise and a long name with QualComm in it shows up.
Tried Power Button + Volume Up for 10 seconds but didn't get any result.
Side note:
The power button was a little faulty before as well.
You have to squeeze it a certain way to make it work.
I need to somehow restart my phone. Any ideas?

Try to clean all buttons really well, if it keeps failing to boot and the phone is still recognized as Qualcomm it's probably bricked.
Simple explanation of the word bricked :
When the phone doesn't boot, when you can't access the bootloader, download mode or recovery it's bricked!

Strange turn of events: I plugged the phone to my laptop because I read somewhere that it drains the battery. Just for the kicks, after a few hours, I unplugged and re-plugged my phone. Suddenly, there was light. The battery light came back. I immediately switched to the wall charger and once I did that the battery icon appeared showing 1%. Now, it's peacefully charging away. Will see if it actually turns on later on once it's charged about half an hour.
