M8 freezes, then shuts off while charging - One (M8) Q&A, Help & Troubleshooting

Hi all. Let me start out by saying that this is the best phone I've ever had, and I've never had any issues with it until last night. I plugged it into my friends car charger which is apparently broken and only works a certain way. When I plugged in my phone, the screen flickered and displayed weird lines and colors. I unplugged it fast and turned it off and on. When it booted back up it went from 20% to 6%.
Now, even when using the original charger, it either freezes and instantly shuts off when plugging it in, (and won't boot up until I unplug it) or it will charge for awhile and then freeze. I was awoken today with it just vibrating non stop, I assume I got a notification and then it just froze. I uplugged it, turned it off and on. And now I'm using it to type this. I just don't understand what is wrong with it.
I'm rooted with the stock Rom still running 4.4.2
S-Off
TWRP recovery (obviously my first instinct was factory reset, but it failed doing a backup, so I didn't continue)

[Q] Rooted G2 fails to charge

Last week I awoke to find my G2 completely dead despite the fact that I had it plugged in all night. I plugged it into another charger and after several attempts to turn it on I still had no luck. Then I decided to do a battery pull. After putting the battery back in and plugging it back into yet another charger the amber led came on, but only for a few seconds. I repeated the process and then was able to turn on the phone when the led came on. At that point the htc boot screen showed but the phone shut back off after that. I am able to enter the boot loader, and the phone stays on, but if I try to enter recovery from that menu, it shuts off in the same way. The weirdest thing is when I try to hold the key combo to boot into recovery, the phone does 2 or 3 little vibrates then the amber led blinks.. I received a new battery from amazon today but the same problems are occurring with that one as well. Any ideas on where to go from here guys, because this is totally stumping me..? Thanks.

Won't turn on or charge???

So after figuring out my signal problem my phone worked great. I flashed CM10, bought Apex launcher Pro, tweaked some stuff, installed freedom then I went to sleep. I woke up to hearing my phone ring when I had turned it off the night before. (Technically it froze and I unplugged the battery because the hard reset woudn't work.) It wasn't the first time it froze, but it only froze while using freedom.
I wake up and it's on and working, but lagging so I decided to turn it off via power button. I go to reboot it and it loads into a black screen after just showing the lockscreen. It wouldn't let me do anything on this screen, so I decided to unplug the battery. I went to reboot and it won't. It won't even boot into HBOOT. I plugged it into a charger and it doesn't show the light as charging.
I found this problem on Verizon forums, but most of the people on those forums seem to only know how to call and text and that's about it. I know this is common, but is there any fix?
EDIT: I rebooted my phone several times with no problems. I just had to go to terminal and do "su" then "killall drmserver" to get the Play Store working.

Phone Turning off by itself.

So I have this weird issue with my HTC ONE M7 for a few days now. It would turn off by its own when I was using it but I'd just turn it on and it will work again. I thought it may have something to do with a bad app or the rom might be acting up. Anyway I ignored it since turning it on was a minor inconvenience and I needed my phone functional. Today whilst using GPS, the phone suddenly went dead on me. Every time I boot it up, it passes the initial HTC screen but then doesn't boot into android. The screen goes black and the phone turns off by itself. I went it recovery, wiped dalvik and cache thinking it was an app causing a boot issue but that didn't help. The problem continued. I already had a backup so I went ahead and tried restoring it. It worked the first time. But the phone still won't boot. It would turn off automatically. Then I tried reflashing it with the backup. This time the phone would just turn off as soon as the restore process started. I finally got tired of it and decided to reflash with a new rom. The flash went fine. But lo and behold the same issue again. Boot animation and then black screen with the phone completely turned off.
I thought it might be the battery so I plugged it in to my laptop USB. It booted but when i was setting up android, it would just shut down again. Then I connected it to the wall socket thinking the phone will get more juice. This time around I was able to set it up. With the phone connected to the wall socket all was working splendidly. Please note that during all this time the phone was at 100% and there were no drastic falls in the battery levels.
As soon as I disconnect the phone from power, any power intensive operation shuts it down. I have been in recovery mode for 2 hours now and the battery hasn't even dropped by 3%.
So the question is, What the hell is going on? Is it the battery, is it phone's hardware or is it a software issue? Any help would be greatly appreciated. Cuz if it's something that can't be fixed, I have to start thinking about getting a new phone then. THANKS so much for bearing with me! Cheers!!

if you are s-off i would suggest doing an RUU and starting fresh. Its hard to pin point a problem without having the device handy and trying some things. The RUU will let us know if its a software problem or if its going to be hardware related.
Hey thank you so much for replying. I am s-off. But would going back to stock re S-On my phone? And how do I do RUU? Thanks again.

Do not s-on! Just run the ruu eye dottat made
Installed RUU. The problem is still there. The phone can stay on for hours in recovery without a charger but as soon i want too boot into android it shuts down. It only boots up if it's connected to a charger and that too a wall socket not a usb hub cuz it goes some way into the boot process and shuts down half way. I am pulling my hair out here. Dunno if it's the battery or the mother board.

If ruu still has issues. It is motherboard or battery. From the symptoms, it sounds like battery as the phone needs to have some juice to fully boot the phone before being able to run off the charger.

LG G3 stuck again!

So it's the second time my G3 gets stuck and won't come back to life. 6-7 months ago it was stuck onto the firmware update screen (thou I never messed with rooting and stuff) and I had to send it back to LG Italy since it was still under warranty. They just wiped everything off, replaced something and sent it back to me.
Today's problem: Phone was off this morning and when I tried to turn it on it seemed like battery was dead. Charged it and turned it on after a while, got into home screen and a weird message about whatsapp loading issue because my phone time wasn't correct. On top of that the phone was totally frozen and didn't respond to any imput, so I had to remove the battery and put it back in. From now on, the phone is stuck on logo screen. Tried to put it in download mode, I see the firmware update screen but my computer won't recognize my phone via pc suite. Recovery mode won't even start. Tried to turn it off and just plug it into my wall charger: the empty battery icon with the loading symbol pops up and everything seems to be stuck, even if I unplug it the icon would still be there. I tried with two different batteries getting the same result
Totally clueless about what to do now (the phone is still under warranty by the way).

SMT700 Won't Boot correctly

Hi. I've got a SMT700 that I purchased new and have used for several years with only minor troubles(Having to reconnect the battery occaisonally) and recently I had a new issue come up I've no idea how to fix. My knowledge on this stuff has extremely large holes in it, so I may have missed something obvious. I've been poking around all week trying to figure it out to no avail.
Anyway, the issue: My daughter was using the tablet and it became unresponsive. I popped the back off and fixed the battery cable(It had come out) and after doing so it flat out refused to turn on. Wouldn't boot in recovery or anything else I could think of. So I plugged it in overnight and let it charge just to make sure, since I wasn't sure if it had had much of one when it turned off. Will not turn on. If you push the power button while it's plugged in, the status of the charge(Says 100%) will blank out and then it resets like I just plugged it in. I've found that if I try to boot it in Recovery, it will come up just fine - if I unplug it, it turns off instantly. If I reset it, it turns off and goes back to the charge status screen as if I just plugged it in. It just has the Samsung firmware installed, I believe fully updated(I rarely check it since the tablet is old and it's literally just used for Disney+ for the kid lately) I'm at loss for what could it causing it or what I can do to fix it. Anyone seen this and able to point me in the right direction? Thanks for your time.
Oh. And I have tried plugging it into the computer, but it doesn't even register as plugged in(Can't do recovery or anything) - that didn't really surprise me, it wouldn't charge that way before so I didn't think it would work.
