LG g2 Shows 0% battery after lcd and digitizer replacement and turns off - G2 Q&A, Help & Troubleshooting

I finally got the right digitizer for my LG-D802, and when I turn it on it will either go through the boot process, and then show 0% battery and tell me it's turning off because of the battery, or do a boot process with what looks like a buffering logo animation followed by a regular speed animation,led light flashes green and blue and then back to the 0% battery and turn off. If connect it with charger turns on by it self and the boot logo runs like slow motion,after some time reboot and does bootloop.
I can get it to firmware download mode, and cannot get it to factory reset. I also cannot get my win 7 to see the phone after trying tons of different drivers.
Please help

Normal Defy Battery Behaviour?

I recently acquired a Defy and immediately installed CM11 on it. My main phone is a Nexus 4 and one of its best features is that even if the battery is completely drained, if plugged into the wall charger it will immediately boot up. The iPhone I had before would show a low battery screen until it reached around 10%, at which point it would finally boot.
It seems that when the Defy battery drops below 15-20%, it will not boot at all - pressing the power button does nothing. I plug it into the mains and the usual white light does not show. It still seems to charge and I can eventually boot into recovery to see that power has reached around 20%. At this point if I disconnect from the charger the phone usually boots up. I haven't had it long enough to troubleshoot extensively but I think that while plugged into the wall it is less likely to boot successfully. An unsuccessful boot starts with the Motorola logo, then the screen goes black and the buttons flash once, at which point the boot fails.
Is this at all similar to the experiences of anyone else, or could it be a battery / firmware problem?
Thanks
Have you tried to remove battery, insert it again and then try to boot?
I had the same problem once, I'm on cm10.2. Maybe we should replace the battery, I always charge it before reaches 30%

[Q]Bootloop and Battery not charging

Hi, so my phone decided to stop working all of a sudden.
I was just doing things on my pc when I heard my phone rebooting, after I had recenly plugged it in.
It's running the latest stock ROM and not rooted. When I try switch it on it shows the Samsung Logo and on some occations some pixels create a fuzzy area underneath the logo text and at the bottom of the screen, it then switches off and after a while tries to boot again. When I try charge the phone it goes to the battery icon with the loading circle but nothing moves and yet again some of the pixles of the battery icon become distorted and then it switches off and tries again(also it vibrates twice before showing the battery icon). I can boot into Dowload mode and my PC recognises the phone(as well as odin) but I can't boot into recovery, or Safe Mode for that matter. I can remove the battery when in dowload mode and the phone remains on but I need the battery inserted to start up anything. I've only had my phone for two months now. Maybe I could be moisture from my shower earlier, I'll leave my phone in a bowl of rice overnight to see if that does anything.
Please try help me fix my problem. I've been looking for a solution all night.
Also due to me being overseas I can't format my phone as I'll lose my WhatsApp validation and all the pictures I've taken so far will be lost.
Thanks in advance.
It's not a software problem so you don't need to format.
My guess would be that you need a new battery.

The battery isn't even swollen though?
I just tried starting up the phone by turning it on, then plugging in the cable and hitting the battery out but it still didn't boot.
Unfortunately I'm far away from a big city so I can't get another battery to test it to be absolutely sure though.
Update:
I just tried booting it again and it got to the other Samsung screen where the LED is Blue and the Logo flashes blue behind it(Only got here once, hasn't gotten this far again yet). I left it for a bit but it just got stuck there and there was the same distorted pixels like in any other type of screen I get to also the logo stopped flashing when I tapped the screen and pressed the home button(this is when the distorted pictures started again).
Here is an attached Image of the flickering part of the screen. It gets stuck on this screen and flickers at the bottom and just underneath the Logo and eventually turns off.
No one know the problem?

It's a hardware failure. Let's hope it's your battery even though it's not swollen.

I tried a new battery today and it had exactly the same problems
So by some miracle it booted all the way to the lock screen and then rebooted from there right back to the lock screen again and I unlocked it and the home screen was fine and the phone seemed to function for a few seconds then it restarted and then got stuck at the Samsung logo again, I did manage to see that there was 17% Battery left so It has enough power to boot it. So I dunno what the hell could be causing it. It's such a weird problem I have no idea of how to fix it(within the warranty that is). I forgot to mention that the screen has 3 stress fracture cracks on the screen so somehow I think it is bending in my pocket, so that might be a reason why it's acting so weirdly.
I also noticed that if I leave the battery out for a decent amount of time and try boot the phone up it boots up for about 20 seconds and then reboots again into a bootloop again. Also the battery percentage is at 0% apon boot, by this stage I've plugged it into my PC to try pull files off of it(Which I managed to get some files off).

Constant restart on charge screen without charging

Hey all
My note 4 910F went out of battery, didnt show any attention cause i would charge it when i went home.
Now it doesnt do anything, when i plug the charger it shows the battery icon and restart all the time non stop.
I tried to boot it, shows the Note 4 logo and restarts back to battery and keeps looping.
I removed the battery and inserted it again, still the same.
Cant do anything.
Any ideas???
The charger is the official by the way
Can you get into recovery?
Only on samsungs, loops in everything else.
I have TWRP but cant get there, only the (vol down / power / home) combo works
I dont think is rom related or something like that.... dead battery ? Shouldn't it open at least on charger ?
It boots on the Note 4 logo and shuts down instant and then loops

Stock G928A will not boot with battery connected

Long-time lurker, first time posting on this forum. I have a SM-G928A S6 Edge+ that is only a week or so old that ran down and will not boot again. No signs of life at all, and no amount or combination of buttons will get it to display anything. If I disconnect the battery (I repair cell phones professionally), and plug the device in, I get the normal charging screen, and the phone will even boot correctly and run for about 30 seconds before rebooting. I replaced the battery with a new one, and it does the same thing. With either battery connected, no button combo, charging, anything will get the display to turn on. Nothing displays - completely black. There is no accessing recovery, no logo, no safe mode; staring at a black screen. If I disconnect the battery, it operates almost completely normally. Bone stock phone. Any ideas anyone?
Thanks!

Battery is fully discharged and doesn't charging - only access is to Fastboot

Hello,
I wasn't using my Moto X Style for some time. I've took it yesterday, and it has a problem with loading.
Battery is fully discharged. I can't turn on my phone.
When I plug phone to charger (I've tried 4 different charges, with different cables), screen is blinking - white screen with battery icon on it. It's showing for around 1-3 seconds, turn off, and again. I left it for whole night, but it doesn't help. Still nothing.
I can get into Fastboot. When I choose any option like Start / Reset Bootloader/ Recovery Mode etc. is showing white screen with Moto logo, than turn off and screen is black, after that I can't get into Fastboot mode, I need to unplug and plug cable again.
I've noticed, that when I get first time in Fastboot mode, I saw red information "Battery is low". Now, after my trying to turn on the phone, there is green information "Battery is OK"
When I left telephone in Fastboot mode, it restart after some seconds, and start blinking with white screen and battery icon.
Any ideas how to turn it on?
I saw in internet one option, to disassembly phone, cut USB cable, and put (+) and (-) wires directly to battery to load it. What do You think?
It sounds like your battery may be completely shot. Battery replacement may be your only option.

I'm thinking, that You are right
I'll replace battery
Thank You
Almost sure your battery is dead, or in a weird case it may be disconnected
I got an used X Style that wasn't turning on at all and it did the same things you described, i popped out the back cover and saw that indeed the battery was disconnected, after putting the connector in place it booted up normally (btw, the battery didn't last too long, it couldn't last more than 20 min and would turn off, so yeah you should change it for better)
