Phone Doesn't Charge or Boot

Hi All,
Recently I have been having multiple problems related to My LG G Pro E98X Indian Version.
1) Battery sometimes drops suddenly. ex From 92% to 40 % in a second. Replaced battery with New one still issue persisted.
2) Charging was too slow, hence tried a New LG Charger and another Samsung 2.1A charger to charge, Seen some improvement.
3) Now 3 Days Before, After charging it for some time it heated and Few time later, it Shut down. And hence from that day neither it is booting nor it is charging.
4) When i connect the phone to Wall charger or USB Charger , it flashes front White LED continuously. When i Press Volume Up+Down+ power my PC detects it as a USB drive for 1 Second and disconnects.
5) Volume Down + Menu + Power Button or Hard Reset also not working.
Suggest any Solution.
Thank you Very Much in Advance, Hope it will be solved.
Regards
Pratik

T-Mobile D851 LG G3 - Turned off on its own, will not turn on or charge

Hello All,
I have a problem that occurred a few days ago with my LG G3 (apx. 6 months old). My phone has been running fine and out of nowhere, my phone turned off and I couldn't turn it back on. Initially, I thought that the battery may have died because I was using a golf app that utilized gps, but my phone was at a 100% 20 min prior to it turning off. When I got to my car, I plugged it into the charger, but I didn't see the charging light and it still wouldn't turn on. When I got home, I plugged it into the OEM charger for about two hours without any success (the phone felt warm similar to when I charge my phone). I've long pressed the power button, tried the power and lower volume button to hard reboot without any success. I bought this through the t-mobile site like my previous phones through their New2U certified refurbished program which comes with a 90 day warranty (expired).
Has anyone experienced a similar issue and if so, what did you do to correct the issue because T-Mobile referred me to LG so that they can direct me to an authorized retailer. Any assistance would be greatly appreciated.
Note: the phone is in great condition.
Thanks

Have you tried removing the battery, holding down the power button until any residual current is discharged, reinserting the battery, then plugging back in the OEM wall charger?

Did you try to go into download mode? Remove battery plug it back in. hold Volume up and plug usb cable. Are you in download mode?

Any word? Does your pc detect it? Kinda in the same limbo... ?

turning off on its own might be due to overheating

Lg G3 d851 turn off
Hi guys i have same problem with my Lg G3 D851. Is turned off after upgrade root but isn't back on. display complete is black, no Recovery mode and no Download Mode. Can you help me?

if you guys are getting nothing when the phone is plugged in either then i suspect either something defective or mobo has lost connection to lcd screen. what roms do you guys use do they make sounds on boot? are you hearing sounds after attempting to turning it on and wait a few minutes?

cm11 Arc won't charge, and battery is 0% - so the phone is dead. is there a solution?

hi.
my xperia arc (lt15a) has all of a sudden stopped responding to the charger - it won't charge at all!
tried other cables, tried connecting the usb to a desktop pc - but no respond!
the battery was at ~40%, and during the night I connected my powerbank to the charger, and the Arc to the powerbank (so trying to charge both of them simultaneously - something I never did).
in the morning I discovered that the phone didn't get charged.
I didn't worry much - I thought it was a bad cable, so I let the battery drain completely to 0%. but later I have discovered that it wouldn't recharge at all, and won't respond to a charger or a pc.
I have tried several things - which probably got the battery to get very drained-out. So now, if I try to power-on the device, it wouldn't turn on at all (it could turn on before), and the led near the micro usb port blinks in red for 3 times.
there is a very very tiny chance that a micro drop of rain got into the micro usb port, before the problem had started. But now I can't see any corrosion - maybe I don't know how to recognize it well enough? Anyway, I have tried to clean the port with alcohol and with electronic cleaning solvent (tuner cleaner) - but the phone still doesn't charge. maybe I didn't clean well? I really tried my best!
this Arc has mikeioannina's CM11 from 17.4.2016 - I used it for several months until now.

the last thing I could do before the battery totally drained out was to enter the recovery mode (by turning the device on while holding the volume-up button), and then performing a factory reset. but it didn't help.
and I also want to mention that initially when the problem had started, when I connected the charger, sometimes the legacy xperia logo had appeared - but without the battery indicator afterwards (the phone just went off afterwards). now even this don't happen, and the phone doesn't respond at all to the charger. that's why I think it's a software problem, concerning the 3rd party rom that I've installed.
the mistake I've made was that I didn't try to reinstall the rom while there was still enough energy in the battery.... but I was abroad, and busy, and without a PC - so I couldn't perform it even if I was aware of the problem and wanted to solve it.
I don't have another battery or an external (desktop) battery-charger. and I am not enthusiast at buying these for this old phone (unless people here would be certain that it would definitely solve the problem).
I really want to keep using this device for a few more months - until the galaxy s8 / lg g6 would be released. I don't want to buy the current devices.
So could anybody help me?

hey i can help

Loop on new battery - help

Hi!
I'm using bountyman rom (so my LG runs a custom). Got 2013 battery yet it somehow started to drain fast - like from 100% to 0 in 30/40 minutes via watching YT in 240p.
While back I've bought the phone, it was sent to me with new? addition battery.
The time of saving ended & decided to put spare one in my phone.
Sadly it won't start at all without charger. If I insert charger nothing happens. Only pressing power button do the job a bit...
By a bit I mean showing LG logo+led flash in a loop of showing it for a sec & goes again with same sequence (not loop of constantly showing LG logo+flash).
So it's faulty & order new one? Help welp.
*it has different V, 3.8 here & my original is 4 something I suppose.

LG G4 death need help fixing

Long story short my g4 died about 2 years ago, has been sitting since. Just one day it wouldn't turn on and I was already fed up with the QoL with the g4 so I swapped.
It has a lot of pictures I really want so I started messing with it. Plugged in, said battery at 0% please charge before powering on. Wouldn't charge at all after a day on this plug so I ordered a new battery. With this new battery I can't even get to this screen, it just boots up and gets stuck on a black screen while vibrating nonstop. Figure maybe something internally won't charge the battery so I have an external charger on its way here. I decided if that doesn't let it power on, then it's likely a bad mobo. Which leads me to my question: how do I get my pictures? Replacing the mobo won't work AFAIK because the storage is on it

Try SALT within download mode (see my sig).
Do a custom backup and choose userdata .
If you cannot get into download mode anymore check the bootloop fix list (see my sig)

I can't do any of that. Can't get into download mode or anything. Is there some way of getting into the devices storage without powering it on or replacing motherboard? I honestly don't give a **** about the phone, I just want the pictures.
I've tried everything except for the stove...

Update: auxiliary phone charger got here, When I try to boot into booloader/recovery it FEELS like its getting into it, but no display shows. Don't know what vibrations omit for X mode, but considering buying an LCD screen rep.
Update 2: Managed to get the LG startup logo to show. Just kept pulling the battery, holding power for 60 seconds w/o sim card or sd card, putting battery in and holding power again, then it finally showed up! Stayed for about 10 seconds then went back to black screen, any ideas what this means and where it's pointing me to fix?
