Random crashes and bootloops - Sony Xperia M4 Aqua

I had my phone plugged in and accidentally bent the USB cord i had plugged into my phone.
The phone immediatly turned off and displayed a black screen, except about 1/4 of it was a green bar, a really loud buzzing sound came out the speaker. This happened for about 15 seconds before it shut off, attempted a reboot, crashed, then booted successfully. Earlier today (this is the day after the charger incident) it crashed and got into a bootloop. It did this for about 5 minutes until it successfully booted.
An hour ago it crashed again, booted fine.
Just now it crashed, booted, immediatly crashed, did the same again, and now its booted.
Any idea what happened? Any idea of a fix? Perhaps the USB port shorted out

Please help, my phone wont stay on

I installed the latest energy rom, and everything was working fine for the last week or so. Suddenly today, I took my phone off charge (was 100% charged) and it was off. When I try to turn it on, it comes on for a few seconds and then switches off. I've plugged it into a charger, but now it just keeps booting and rebooting. Some times it gets as far as booting up completely, but then reboots.
Please help.
bent battery pins are first thing to check.

[Q] SGS2 won't turn on - probably NAND probs

Hey guys,
my I9100 died this morning. It won't turn on. It even does not show the charging icon, but I have a glimpse where the problem is located at: The NAND.
So some background: Yesterday, I plugged the phone onto my computer. Windows came up and said the storage is defective and it should be checked. I didn't thought about it and commaneded to do it. So everything was fine. Everything still worked.
The problem appeared this morning: I couldn't start Ingress. It always crashed with an IOException at booting up. So I wanted to clear the app's cache. The phone was calculating the sizes and then stuck. "Okay. No Prob. Just reboot." So I did and put it into my bag, because my ROM (Vanilla Rootbox) needs some time to boot. After some minutes I checked again and saw it stuck the Dorimanx bootscreen which I had disabled. I tried another reboot. It came up with the typical "Samsung Galaxy S II" Logo and the blue bar down it filled and it stuck again.
I tried another reboot by taking out the battery, but since then it doesn't turn on anymore. No Power+Home+Vol Up/Down; no charger; nothing.
With attached battery and charger, it get's hot around the camera lens, but nothing more.
I even tried another battery, some time waiting with battery and without battery; charging and not charging, but still it's dead.
So I think, Windows somehow managed to kill my NAND.
Any ideas?
/edit:
With the battery plugged in, it just get's warm.

[Q] Device won't respond w/o charger, and even charging it fails to boot

So... My dad bought this S2 for him a couple of years ago, and on the first 15 days, he let it fell, and the screen broke, but he kept using it like this until around 3 months ago...
Now he has a G2, and the S2 had no use anymore, and I thought about using it as a dashcam on the car...
Installed dailyroad voyager on it, and used as dashcam for about 15 days...
Then today, I got on the car, it was off, but with the charging cable plugged in, I pressed the home button, it said the battery was 100% charged, so I tried turning it on
It went until the animation that plays when booting, but restarted, I tried again about 5 times, each time it rebooted a bit early than before
It got to a point where it didn't even reach the animation, just the "Samsung Galaxy S2" appeared on screen, and rebooted...
Then I tried going on recovery mode, and it worked, so I cleaned the cache partition, made it clean user files, etc... then pressed to reboot, and still didn't work...
So I thought it could be a battery problem, and unplugged the cable while it was on the recovery screen, and it didn't turn off, I let it on the recovery screen, and went to do some work for about 2 hours, it was still on
Now it won't do anything without the cable, can't turn on, can't go to recovery, and even with cable plugged the "Samsung galaxy S2" screen won't appear anymore, and I couldn't get to the recovery screen anymore....
Here's a video of the actual situation:
Does anybody knows what's happening and how to fix?

Bootloop

Hey, so, firstly I have a blue life one x. I love the phone and haven't had any problems until now.
I got an android update and my phone restarted, which has happened with the last two updates I got, so I didn't think anything of it. However, my phone was practically dead when this started and it restarted and got to the screen where it says "Android is starting... Optimizing application 1 of 143"
It would get to around 100 and turn off, restart and get to about 100 and turn off again.
I googled around and found a thing called bootloop. By what now seems to be a stroke of luck, my phone eventaully charged to about 40% and I got it to turn on and everything was fine but a few days ago, it died again and I ran into the same problem.
I went back to the boot loop instructions and tried it to no avail.
My phone has a fixed battery, so removing it wasn't an option. I left of the phone off the charger for 30 minutes and held the power button for two minutes(to discharge any remaining power?). Plugged it back in and it went right back to trying to boot back up and optimize apps.
I then removed the case, detached the ribbon that connects the battery to the board, held the power button for two minutes and let it sit for 3 hours. I connected the ribbon, plugged the charger back in and it instantly tried to boot up back into the optimizing screen and turned off.
I did all this again but left it for the past two days and now its back to rebooting over and over...
Things of note:
The light indicator turns red when the phone is connected to a charger, whether the battery ribbon is connected or not.
When it displays the blu splash screen, the optimizing applications screen, or recovery mode, the light indicator is off.
I can get into recovery mode, but I can't do anything before the phone turns off and reboots again.
Any help would be appreciated!

continuous rebooting Mi8lite

Today at noon, I slept a little and left the phone to charge. When I woke up, I was on the phone for about 15 minutes after which it began to restart continuously. He had no problem before. I tried to enter recovery mode, I went in, but after a few seconds phone restarts. And if I get into the fastboot, the phone also restarts. What could i do and what could be the problem?
I'm sure it's physical problem, but you could try to reinstall the last official room from miui update. If it persist after that, you have to send it to repair.
