G Flex 2 keeps shutting down - LG G Flex 2

I recently dropped my phone on the ground and the glass is now broken. But it worked normally for about 14 days. Then suddenly one day at work it shut down on its own. After that I wasn't able to start it. No reaction for any of the buttons, nor their combinations. Even when I plugged the charger in, no sign of life. I thought it's over.
Then the next day, I plugged the charger in and the screen with 0% battery appeared. So I left it charging, but when I came back to it (20 minutes) it was dead again. Not even the diode indicating it is charging. Again no response for the buttons, nothing. So I tried to disassemble it, disconnected everything. Put it together and viola! The screen indicating 0% battery was there again. I left it like that for a while, and when it was charged a little, I tried to start it. It started and normally worked. At least it seemed to, but after a while (1 - 3 minutes) while I was using it, it went to the dead phone again.
So I discovered, that when I disconnect the battery for a while and then connect it again, I am able to boot the phone. I was even able to do factory reset. I thought I got it and that it was some software fault. However after like 5 minutes (it downloaded all apps, logged to my google account, looked all ok) the screen shut down again and again the phone played dead.
Now I have the phone booted, and charging (almost 100% now). But I guess when I start using it again, it will again go to the dead mode (since it did it everytime after I used it a little, no specific action done, totally random).
I guess it has to be related to the broken glass. Maybe some water or humidity got through it and the phone is trying to save itself from damage by going to the dead mode. It's weird because sometimes (like now) the phone is OK when not used, normally chraging and not shutting down (now it's ON for about 40 minutes), but if it shuts down, it takes about 3 or 4 battery disconnect and connect again, before it boots to the main screen. Sometimes it just dies before the screen, sometimes it dies when I try to plug the charger in, really no idea what causes it.
How should I diagnose it? USB debugging and check the log when using it and when it dies? Or has anyone experienced this too? Or could the battery be damaged? Or can I somewhere set the phone to prevent from selfkilling actions? Today I will try my main board in my friends G Flex 2, to see if it's the board, or something else.

Adding the error log from console

OK so it was probably mother board fault, so I had to buy a new phone It is like 3 months, and I just yesterday accidentally poured some water on it, so i destroyed another one. It is still in warranty but I guess with water damage there is no warranty. Anyone knows where to find all the water damage indicators? Or is it even possible to make it look like there was no water damage?

Water damaged - now flashing green and orange. Wont turn on.

After my issues with my One X, my daughter looks to have bricked her One S after dropping her phone in the sink....
Early on Saturday morning my daughter ran through shouting that her One S had just fallen from her pocket and landed in the sink. It was in the water just a second or two. She brought it straight through to me and it was working fine, but the phone was on a constant vibrate. I pulled the sim, and removed the top and bottom cover, and got the hairdryer out. I dried it on cold for 30 minutes (no heat at all) and put it straight in a sealed tupperware box of rice in the boiler cupboard. I had expected to pull it out this lunch time (a full 48 hours later) expecting it to be fine, but after plugging it in to charge on the mains for 4 hours, it wont boot.
At the moment it flashes green and red when on charge, but this disappears when it is removed from charge. This is the same whether it is charged via USB or mains.
When I first tried to start it up, the screen flashed around a third of the way down and the nothing.
Second attempt, I held down the lock button and held it. After a few seconds the three buttons at the bottom flashed 15 (I counted them) times and then nothing.
Third time, as above, but flashed 5 times.
Since then nothing. No flashing, no noise, blank screen.
Incidentally, when it seemed to want to boot it never vibrated (if that helps the diagnosis?)
I haven't got the tools, so I had planned to pick some up tomorrow and order a replacement battery from Ebay. My reasoning is because I have read that the lights I have flashing relate to battery issues.
Any other options? Is there any hope for this phone now?
AW: Water damaged - now flashing green and orange. Wont turn on.
Does it geht recognized when you plug it into you computer?
OK I don't know of it even gets recognized if its turned off, bit its worth a try.

It could be that the device has 0% battery.
Try to plug it in the charger and hold the power button for so 15 min.
Then try constantly to turn on(plluged im the charger)
This should help

No no no don't plug it in! There's likely still water in there that could short the circuits and permanently damage the phone, if it hasn't happened already. Power it off fully, put it in rice or some sort of dessicant, and let it sit for at least a week. The longer you wait, the better chance you have of saving it.
Thanks guys for the quick replies.
The phone won't connect to my laptop or computer and won't let me access HTC Sync. The 3 lights at the bottom will only flash when the phone is plugged in, if I unplug it won't do anything at all.
I can't see there being any liquid left in there at all. It was thoroughly dried with a cool hair dryer (and worked perfectly) before I shut it down manually and placed it in the rice for 2 days. I think that I'm at the stage where I can be confident of that.
Sounds like a dead battery to me.. But just to be safe wait a while before charging it

Update:
I was ready to bleach the water marker and/or get some phone insurance, but when I went back to the phone a couple of days after my last post, I plugged it in to charge again and when I checked it a couple of hours later it was working.
it's well over a week later, and there are no obvious I'll effects now.
I'm really surprised, but obviously delighted.

Almost dead Nexus 5

Here's my little story. I dropped my N5 and cracked the screen. It worked, but I wanted it to be pretty again. So I bought a screen/case and proceeded to do the swap. I watched several videos, read guides, etc and followed them step-by-step. After it was done, I was surprised how smoothly everything went. I then went to power it up and got nothing. I checked all the cable connections, reseated them, and still got nothing. I put everything back with the cracked screen. Still nothing. I check the cables carefully, there are no cracks or breaks in them. I left it on the charger all night and the next day, checking periodically, still nothing. I checked the battery connector with a multimeter, and it was getting a reading off it, so the thing must be receiving power, right? Anyway, I gave up for a few days, busy with the rest of life.
I came back to it one day, plugged it into the charger and this time I got the red blinking light. I searched around, and that seems to indicate the battery had lost it's charge completely. Again I charged it overnight, still nothing. I got adventurous and removed the battery and tried powering it with just the power cable plugged in. This time it displayed the charge full battery/lightning icon. Success! I hit power and it starts to boot, displays the Google logo, then shut down after maybe five seconds. So, it must be getting power through the system from the USB port. The mainboard/cpu/screen works, it's able to start booting. It even boots to the bootloader, keys work there.
Again I turned to the problem being the battery. I picked up another, thinking perhaps mine had gone bad somehow even though I never had a bit of trouble out of it (about 1.5 years old). I played with it some more, with either battery inside, it doesn't do anything. Without a battery, it starts to boot but gives up. Hoping I could get something from the bootloader, I plugged it into my PC, but the USB port doesn't seem to provide enough juice to get it back to the bootloader with no battery.
Finally, during one of my tests, I plugged in the battery while it had the charging cable in. Then it popped up the battery charging animation. Exciting! It must be successfully charging, now. Previously, it didn't display anything when I charged it for many hours. Now it's been charging about six hours. The battery animation still shows it filling from the bottom, usually it would blink the animation from like halfway to the top, right? I hold the power button, and the battery animation disappears and it goes dead yet again. I run the same tests, battery in, battery out and get the same results. It boots when there's no battery and the charging cable in, nothing when the battery is in with or without the charging cable.
So, here I am stuck again. Any other ideas? Thanks.

Not Charging or turning on. - my fix

Hey guys, this may or may not help anyone or may or may not have been posted but saved my arse when I thought my phone was fubar
Basically the phone died on me when charging with 20% juice left. It just would not turn on or charge, tried multiple cables, seeing if recognised in Pc, trying to power on holding different button combinations etc etc and still nothing.
Anyway, next to the sim/sd card slot is a little yellow button. Stick a pen, screwdriver or whatever in there and hold down till it comes alive (took mine about 35 seconds). My phone turned on at 100% battery and all data settings etc as it was, so it looked like it was actually charging prior with no indication.
Hope this helps anyone and sorry if already posted.
@Adster013
I came to here to write same thing After washing my z5, i wait 4-5 hours to charge again. Tried to charge but no luck with travel charger or pc. I opened TWRP, wiped cache and dalvik.. Then i push the yellow button 10 seconds. Phone vibrates.. Then put into charger, it starts charging :/
IP65/68 means NOTHING!
I'm having probably the same problem, but no mater how long I hold the yellow button the phone doesn't show any indication of waking up. I'm wondering if it from the last update I receive last week. I have opened a thread about it here with full explanation https://forum.xda-developers.com/xperia-z5/help/responece-idication-z5-black-screen-t3610295

Possibly Bricked, Never-flashed/modded Mate 9?

Last year I picked up a Huawei Mate 9 (MHA-L29), but never really was able to use it as I couldn't activate it with my carrier at the time. So the phone sat in the box for more or less a full calendar year. It was fully functioning, I never rooted or flashed any kind of ROM/recovery on it, 100% stock.
After changing carriers, I decided a few days ago to try and activate it. Initially, it wouldn't power on at all. It wouldn't charge either, even with the original cable (or any other cable I tried). Then I remembered reading something about batteries in a Reddit thread (ELI5: "Why do 'dead' batteries work when you take them out of the remote and switch slots," or something like that) and somebody mentioned a chemical reaction triggered by the body heat transferred while handling them. So I decided to put the phone in my pocket and warm it up between my legs for about 10 minutes, and bam, suddenly it would power on with the charger connected, but it was stuck in a bootloop, wouldn't bring up the charging animation, and just repeated the process of showing the "Powered by Android" screen.
So now I'm stuck on this bootloop, can't access recovery/fastboot menus, nothing. It just powers off and powers on, over and over. Also, it won't power on without being connected to the charger. I've let it sit for as long as an hour or so charging, but it doesn't seem to do anything, as once it is unplugged, it immediately turns off. My computer doesn't seem to recognize it either, when plugged in and going through it's bootloop cycle.
Any ideas? Is this thing hardbricked? Is the battery a goner? What route might I take to go about fixing it, or getting it repaired? Is it even worth trying to get it repaired?
Any feedback would be appreciated!

Duraforce E6560 boot loop

I've had this phone 3 years and it worked well. It's an unlocked ATT phone so no OTA updates other than the standard app updates. It's on Lollipop 5.1. Been working perfectly fine until yesterday, I was watching the CBS app, when the phone rebooted. Now it's stuck on a boot loop and initally went to optimizing apps which it rarely finishes but the times it does, the phone just powers off. It then got into another loop later last night where it'd get to the Kyocera logo then reboot over and over. I let it do that until the battery died 2.5 hours later. Then I kept attempting to boot until the batter was entirely drained to the point it wouldn't attempt to power up any more.(battery is not removable on this model). I've now charged it up, trying to enter recovery mode with power+volume down. That doesn't seem to register. Tried volume up+volume down+power with no effect. Now after charging, it will do the reboot loop mentioned earlier to the Kyocera logo. If I plug it into a charger, it will go to the optimizing apps portion and repeat the above. At the optimizing apps screen, if I unplug the charger, the phone powers off immediately. It appears to be holding a charge according to the charge indicator and the fact that I can try to boot over and over unplugged. Any suggestions? Phone wasn't dropped or damaged in anyway. Very weird what could have happened.
An update: Phone finally got past the "optimizing app" phase last night sitting on the charger. Out of no where the phone booted completely. However, it only works while plugged in. If I remove the charging cord, the phone shuts down after about 2 seconds. Booting without charging cord results in the same boot loop. I've considered the battery has failed however when plugging in the charger, battery shows 100% and it will decrease appropriately over time. I'm thinking there must be a hardware issues at this point. Somewhwere in the charging/power circuit. Any other suggestions?
Last update I guess. I was able to keep the phone up and booted as long as it was plugged into a wall charger. PC USB was not enough. I managed to grab my photos etc. thankfully. Factory reset the phone from the settings menu. Unplugged from charger, ran for about 2 minutes. Still said 99% charged, then went into boot loop again. Phone still shows near full charge if you let it run for awhile and decrements the charge state appropriately as time goes on. However, i guess this 3 year old phone is toast. No known reason for it to fail unfortunately. Thought I'd share the experience if anyone else has this issue.

I have the same exact problem. It started the crazy booting process in my pocket, and I did all the same things you did. Factory reset didn't correct the problem, so I'm think the battery has had a stroke. Sine your problem and my problem are very close to the same time frame, our phones are also probably about the same age, and its a quality control issue. Not bad quality control, just that these batteries were designed to last X number of months or cycles, and probably they died. Too bad, because my E6560 is the very best cell phone I have ever owned. Built like a tank and thank God for that.
