[Q] phone not booting when unplugged - G3 Q&A, Help & Troubleshooting

So im having a bit of a conundrum. My phone doesnt boot when unplugged. And it actually works fine if i plug it and charge the phone. The second i pull out the cord, the phone shuts down and wouldnt boot past the initial logo. I tried data wipe and flashed cloudyg3 fresh but its still happening. I should also note that this doesnt happen if im in recovery mode.
what should i do? ._.

bricked one x

usual story.
got an htc one x. flashed unlocked all going well. installed a bad rom (did not make a back up)
froze at splash screen. only late last night i found disaster recovery, so i put it to download and shut off the phone. boot back up this evening and tried to install recovery re-lock bootloader, clear cashe etc but. i got a low battery warning when trying to flash.
i didn't have the latest clockwork mod for charging installed; and battery is too low to flash to it.
this is where things get different. i used the boot loader to power down. i plugged it in to the wall to charge and i got this strange flashing red led(not orange) after about an hour it went solid red. had it charging from the wall socket for well over 4 hours now with the solid red led.
then all of a sudden the led starts to flash red again. so i disconnect the phone and try to boot.... nothing happens. try bootloader mode(power + vol.dwn) nothing.
i had to hold the two buttons then plug in the wall charger. then it went into bootloader. problem is it says relocked AND security warning....... and still after all that time charging. i still get low battery warning @ flash.
so i tried to turn off the device again using the power down option. two things happen here. 1)if the charger is in the screen goes black and instantly restarts to fastboot usb menu. 2)if it isnt in it will turn off and wont turn back on (splash screen or bootloader) until the charger is back in.
so what ive done as of now is plug it in to charge over night and hope this thread can shed some light.

os version: 1.28.707.10
clockwork mod version: 5.8.2.7
plz any help would be invaluable
EDIT: just turned on phone about ten minutes after i plugged it back in to the charger (held power button alone) splash screen is back (yay!!) but still battery low when trying to flash in
fastboot usb. ima try in the morning after a full night to the charger. fingers crossed
good luck to you and your phone. i was afraid of these things too, so before i started to do anything, i saved some roms onto my virtual sd card, just to be sure if i get stuck without a operation OS, i still have some roms on my memory. and before starting with anything, i charged my phone up to 95%.
sorry, i can not help you and i guess you have to wait for a solution.

[Q] Can't boot into recover, Rom won't boot, and PC doesn't recognize USB

It's been a fantastic day for me.
I was in the middle of a nandroid restore (TWRP). I was restoring a PAC Rom, and the ROM I was running was MROM (I liked the Rom, but it didn't have the Nav Bar, so it wasn't for me - it was running fine).
In the middle of the restore, my phone turned off. I was relatively close to 100% battery when I started to do the restore.
When the phone turned off, I tried to turn it back up, and it kept looping. I then tried to enter recovery, which I did. I didn't want to try restoring again, so I started to wipe with the intentions of flashing a fresh rom. But the phone turned off again. Now, it still won't boot up, and now I can't enter recovery. I get to the TeamWin screen, and it turns off.
I can enter download mode.
However, for the last several months, my computer never recognized my phone. Today,I've tried maybe five different usb cords (2 are S3 OEM) and four different USB ports. I've tried with Kies, and I have removed Kies. I tried with Odin open and more. No luck. I think my phone's usb jack is busted, but it charges fine from the computer.
My wife has an S3, too. Last I checked, she connects just fine to the computer, but she's at work now.
What do I do?
Can I somehow use my wife's phone to fix this awesome problem?
UPDATE: The USB port/jack is messed up. I am going to try and get the warrant to cover it.
I just tried another PC with no luck, too.

Phone only stays shows Sony Logo for a second and shut off

Hey guys.
I am having a problem with my phone (C6503) is when I boot up my phone, it will show the Sony logo for a second and shut off again. When I plug my phone into the charger, it will do this in a loop.
This all started when I flashed MIUI v5 from here (I have a locked bootloader, and it can't be unlocked): ( http://forum.xda-developers.com/showthread.php?t=2520793 ) and I was simply using it one time and it was suddenly shutting off on me. The phone would also would also say the battery was at 85% then shut off on me and when I turned it back on, it said it was 5%. It got worse, when I powered on my phone while the charger was in, it would boot up, and when I unplugged the charger, it would shut off. Now, when I power on the phone, it displays the Sony logo for a second, and then shuts off.
Thankfully, I can still access Flashboot and FastBoot mode on the phone when it's plugged into a computer.
At first, I thought it was my ROM that I flashed earlier, so I tried flashing a stock ROM that I came from earlier. I tried a couple of stock ROMs and it didn't work, I also tried flashing stock kernels to it, too, and no change. I'm starting to think that my phone could possibly be dying on me from a hardware prospective instead of a software prospective, and it may not be the ROM I flashed earlier, since I was able to use it earlier before this started to happen.
Any help will be thanked.
I`m having the exact same problem (it started when I flashed the same rom, btw), did you find a way to solve this?
I have this problem too... my xperia is c6504 and I can't find a stock for it, I tried everything.. need help

D855 Stuck in Bootloop-- Light Sensor and Vibration Still Work

I'm having a weird problem. Yesterday I was using my phone as I normally do-- texting, playing simple puzzle games, etc.-- when I noticed the battery was at about 2%. I wasn't very concerned so I tried to send one last text before it died. Shortly afterward it died with the usual "Powering Down" alert. I thought absolutely nothing of it and once I had access to a charger, I did what I normally do: I turn on my phone, wait for it to get past the LG splash screen, and I plug it in once it gets to the boot animation. I do this so my phone will turn on instead of going into charge only mode. Also, like usual, my phone's screen dimmed seconds after the boot animation began (I assume from my automatic light sensor settings), and I could feel it vibrating a little (also something it typically does upon boot).
However this is as far as it got. I was very confused when about an hour later, the phone still hadn't completed boot. I removed the battery, inserted it again, and tried once more telling myself that I would wait as long as I could instead of just an hour. Booting the second time gave me identical results-- everything is normal (light sensor response and vibration indicating the phone is powering on) yet it gets stuck. The only difference is that this time I got to see the entire bootloop.
After the boot animation screen has run for a while, I get the usual "Android is starting.... Optimizing app ## of ##" (#= actual numbers). Once it finishes, instead of booting my phone, it begins the boot animation again. If left alone it will cycle between the boot animation and the "Android is Starting" screen indefinitely.
TL;DR:
1. ) Caught in bootloop between boot animation screen and "Android is Starting... Optimizing app ## of ##" screen.
2. ) The screen still dims and there are little vibrations that usually tell me the phone is about to turn on.
I have tried:
- a hard reset- this yields only a slightly stronger vibration and it starts the bootloop again.
- Download mode- this does the same as the hard reset
- Removing battery for a while- no results
- Full charge to completely dead to full charge again on charge only mode- no results
I am running CM13 Nightlies from late February (not completely sure which exact date). Which I flashed without issue about a month ago. I do have Xposed and run various modules, but I was using nothing at the time and hadn't for about a month. My computer recognizes my phone as an LG G3 Device, but refuses to access any files.
Any help would be greatly appreciated!!
Phone not starting.
First remove phone battery, insert it again, do not start phone. Connect your phone to original charger and charge it, while charging with the charger start your phone. Your phone should start if yes/no report me immediately. Your phone battery is failing to start your phone (Due to Low Voltage in battery). Replace with original battery.

Alright, I removed the battery, reinserted it (without turning the phone on) plugged it into the wall charger (seeing the charge only battery animation), and attempted to turn it on. Whenever I try to turn my phone on after plugging it in, I get the LG splash screen followed by the battery charging animation. It never reaches the boot animation. I'll let it charge for a while and try again.
Thank you for the advice!
Okay, I let the phone charge completely and attempted to turn it on whilst plugged into the wall charger again. Unfortunately I had the same issue. The phone shows the LG splash screen and then the battery charging animation again-- no boot animation.

Yeah, I'm trying to avoid a full reflash/data wipe. Since I haven't messed around with any Xposed modules or root apps, I also haven't backed up anything for quite a while. No abnormal apps were running before the battery died, which leads me to believe this can be solved somehow without a full wipe.
Also, I tried to use my boyfriend's battery to boot up my phone. I thought it might be a bad battery-- as some people on-line have mentioned. Unfortunately, it still refused to boot and it produced the same bootloop.
You see , if and not and this and that dont help . te only way to save files is to get acces by recovery or boot, you cant boot but possible you have recovery so start saving your files you need. when you have or dont have your files . you stil need your system to boot for that to happen, it needs to work. so flashing a default rom with wipe sould work if it doesnt you flash original if that doesnt work its dead

I think I forgot to mention, I cannot access recovery mode. I have the latest TWRP installed, but attempting to boot into recovery gives me the same results-- endless bootanimation/ "Android is Starting" bootloop.
So no acces at all . so what do you do ? Read above! Anyway good luck

Solved
I fixed my problem. It turns out I was being an idiot and got the method of entering recovery mode on the LG G3 confused with my Samsung tablet. I should be able to fix the bootloop on my own now. Thanks everyone for your help! Cheers to idiocy.
Hey, I have the exact same issue right now. Did you solve your problem, and how? I tried removing the battery and charging with original charger to 100%. I connected it to my PC, went into Download mode and clicked "Restore Upgrade Errors" in LG PC Suite. It successfully flashed the firmware update, then it said "Android is starting.... Optimizing app ## of ##". But after that it restarted into bootlop again. Also I noticed that sometimes it vibrates, and my LED (light sensor) doesn't light up anymore.
Any advice? I haven't tried replacing the battery yet.
