cannot turn on phone anymore

New issue ..
Today i didn't have a charger with me so phone drained completely. Now it no matter how long i charge it it will not boot right.
This is what it is doing, two kind of behaviors:
1, when it is plugged into an outlet screen remain slightly lit, able to boot into bootloader, able to boot into recovery (once phone turned off itself in recovery..). when trying to boot into android phone hangs on LG loading screen and LG loading screen disappear as soon as unplug the phone from the outlet . LED light remain off while plugged in, it should be lit when being charged.
2, when it is plugged into a computer phone seems to boot itself, LG logo flashing on and off quickly seeming like bootloop.
I have flashed the rom again it didnt help.
Edit 1: fixed by factory restore

CWM supports charging your battery, so use the strongest charger you have (spec is 2amp charger) and leave it there for a few hours. the reason it flips on usb connection is because most usb is only 0.5 amp or maybe 1amp if you're lucky.
You should be ok gotta be patient though.

Yea you just have to leave the charger in for a while..mine did this...but you can also try this
Unplug the charger hold down the power button of 15sec and then put the charger back in (the red light should come on)
Then the screen will show the LG logo about two times and then the battery charging logo
And just give it a minute or two and power it up
The LG charger is 1.2a

[Q] Phone won't boot, can't enter download or recovery

A few days ago my phone got soaked through my pants as I was working in the rain. I came home, dried it out, etc. and tried to turn it on. Wouldn't turn on, so I started charging it. I eventually got it to turn on and it seemed to be working fine except for some reason it said the battery life was at 0 %. Note that it was still working normally otherwise.
I went into recovery, made a backup, and did a factory reset to see if that would fix the problem. It didn't, so I restored the backup. Now the phone won't turn on at all.
When plugged in, it shows the charging battery symbol, and if you hold power to turn the phone on it will sometimes begin to start, but it gets to the boot animation and simply stays there forever (I've left it at the boot animation for several hours to no effect). If I try to boot into recovery it simply does not work; it will either just restart the battery charging animation or boot normally (and then get stuck on the boot animation).
In a last ditch effort, I was going to try to flash a stock ROM from Heimdall. However, I plugged my phone in and tried to enter download mode and was greeted with the error: "LOW BATTERY!! CAN'T DOWNLOAD!!." This was after charging the phone all night. I then proceeded to charge the phone for another hour then try again, to the same error. And now here I am. It seems the problem is that my phone will charge, and the battery will be full but for some reason the phone doesn't recognize that the battery has a charge, so it just thinks it's at 0%. I've tried a different battery and was unsuccessful. Is there any way that I can either force my phone to enter download mode or somehow get it to recognize the charge on the battery? Or is there some other way I could resolve this? Or is my phone simply gone for good?
I am (was) running a rooted I777 with Slim Bean ROM ( I believe v8) 4.2.
Have you tried using a JIG it can be an option
If a JIG doesn't work you can try removing the battery, then plug the phone to the PC and go to download.
But for me the problem is with the battery. If after flashing the ROM you get the same results, don't think it and BUY A NEW BATTERY.
Good luck.

I has the same problema, I spend two days searching on the web, but i didnt have any idea.., ,y problem is. when we conect to ANY charger (car/wall/PC-USB..) appears on screen a batery logo, but the batery never charged..., I tried to enter to the CW but, the keys combination doesnt make anything on the phone, and without live on it, I cant access to CW..., I wait for 2 hrs, with these cell phone conected to charger to see if the it gone works...
ANYONE has another idea for how we resolve these issue? My phone has a stable version of CyanogenMod..
same with me but what i did was put a different battery in, let it charge for a bit then put the original one in and it only started charging after i used my car charger as i was driving to work so thats how i fixed mine.

Poco F1 on Pixel experience (PE11) stuck in bootloop

Hi Community,
Everything was working fine and couple of days back, my poco F1 on PE 11 started acting wierd. I had to boot it while plugged in or it got stuck in bootloop. But once I boot it, it will work without any problem (unplugged). But since this morning, it won't start or work without plugging it in. And when I stop charging it will work for a while(mostly well until i press power button to lock or unlock) but suddenly goes off and goes in bootloop.
charge percentage also acts weird. While switching on without plugging in, it sometimes shows 0% charge but when I plug it in and use for 10 minutes, battery goes Normally from 1 to 20% and then suddenly it shows 100%.
I opened twrp recovery (which works without plugging in) and kept the phone in recovery for 2 hours, i know it doesn't drain much battery but it just went from 100% to 97 %
Did anyone face similar problem? I am not technically sound in these things. I need help from you guys to get this monster working. Thanks in advance
The reason why I kept it in twrp recovery for couple of hours(unplugged) was to check if it goes off in recovery mode but it didn't.
Here's one similar thread i found but not sure mine is a battery issue since it suddenly started misbehaving.
