P500 Power Cycling Hours after Flashing Oxygen Rom - Upgrading, Modifying and Unlocking

I flashed my LG Optimus P500 with the Oxygen 2.3.2 rom yesterday, and it had been working great. I spent a few hours customizing settings and getting acquainted with the layouts and everything. I'm pretty sure I rebooted it at some point.
But then, about 6 hours after flashing it, I held down the power button and pressed reboot (after opening a bunch of apps that I didn't want to bother closing. Once it shut off, it didn't come back on automatically, so I tried to manually power it on. It didn't come on. So I plugged it in to charge. The battery level was at 7 or 8% when I did this. Then when I tried to power it on, it just showed the battery charging that typically comes up when it's off. I held the power button for a few seconds and it booted up as usual, but when I spent a few seconds on the home screen, it went back to the Oxygen logo for about 10 seconds and came back to the screen lock. Since then, it keeps power cycling on its own. I can't keep it on for more than a few seconds. Sometimes, it gets stuck at the screen lock and I can't even press anything on the touch screen or the power button, and I have to do a hard reset.
I tried booting with no SD card and the same thing still happens. Should I reflash it? Any help would be appreciated.

Tablet not powering on? Brick?

The device responds to any button presses with the image that says 0% battery. When plugged in long enough it stays on "Needs more power to turn on." It has power, it can continuously respond to button presses with that bright image for hours on end. Attempting to boot into recovery/download mode responds with the same screen no matter how long I press it. Holding the power button for any period of time while unplugged results in it showing the battery 0% and then going to blank screen a few times then staying on a blank screen while immediately responding to any other button presses with 0% battery. Holding it while plugged in results in an infinite flashing 0% battery logo that flashes on for a split second every few seconds. Help?
Something similar has happened to me.
I installed TWRP and CM11 on it a few weeks ago. It had been running fine. A couple days ago I accidentally let the battery run completely out. Now it won't charge or power on.
It doesn't appear to be charging at all, doesn't get warm like it normally would when charging. Pressing the power button does nothing now, first time I tried to power it on I saw the plug image indicating no charge, but now I get nothing at all.
I've tried holding the power button for 30 seconds (and longer). I've tried holding the power and volume down buttons together. I've left it plugged in all night. It seems to be completely dead now.

[Q] Bricked help/ideas

In short, the phone is stuck in a bootloop unlike any I've read about before. All on its own, it constantly makes the bootup vibration pattern but it does not boot up. The screen does not light up, it is completely black (backlight is off as well). It is sitting on my desk doing the vibrate patter (bzzz-bz). Then 40 seconds later, again, (bzzz-bz).
If I could see the screen, I imagine it is going past the 1st Asus Logo screen, then trying to load the OS (2nd Asus Logo), but crashing and restarting.
This happened after I flashed fastboot (droidboot), recovery, and boot. All flashed successfully, so I went into Recovery and started to "wipe cache". It was taking too long so I thought it froze and forced a restart. After that, I never saw the screen light up again.
Any ideas as to what is going on? The phone has no damage (at least physically ).
Yes, wiping cache takes a long time you have to wait it out, forcing reboot before it finishes will result in bootlooped, that is covered in many many threads, you will need to reflash entire Rom from bootloader.
Problem is, I cannot get into bootloader. Its still doing the vibrate cycle I described, it's been 8 hours already.
Try holding the power button and volume up toll you get 2 vibrates then release power, if that does not help it sounds like your power button is stuck in depressed mode
Stuck in depressed mode? But I am able to press it, and I hear it click, and click back up. The "spring" seems to be working fine.

Stock phone off and unresponsive

My phone suddenly would not turn on, no button combos work. I even tried combinations of button combos and pluggin/ unplugging the charger
I also took the back off and tried a battery pull, nothing has changed
the phone was charging all night and i have also tried charging it for an extra half an hour before trying button combos.
Any ideas?
UPDATE: I tried the vol down + power button combo again after letting it sit for a half an hour, and it went into the boot menu. I selected recovery. It booted into recovery, then after about 5 seconds it froze for about another 5 seconds, then it rebooted itself, and then its back to being unresponsive on a black screen...

G3 VS985 difficult to turn on, recovery mode buttons don't work

My VS985 has 2 problems, which may be related to each other. The first is that, when the phone is fully turned off, turning it back on again is difficult. When I press the power button, the phone just vibrates at me and then refuses to turn on. Screen doesn't light up or anything. Pressing the power button again does nothing at that point. What I have to do, sometimes up to 7-8 times before it turns on, is remove the battery, wait a few seconds, put it back in, then press the power button again. It'll vibrate every time, and eventually one of those times it will turn on and boot up.
The second issue is that I've found it impossible to get into recovery mode using the buttons. I can get in just fine using the quick boot app, but that's not much use if I ever end up in a state where I can't boot into the OS. Apparently it's supposed to work by turning the phone off, then pressing and holding the power + volume down buttons and waiting for the LG logo to show up. I've tried this many times, it never works, possibly because of the first problem.
I bought this phone used, immediately used ODIN to downgrade it to the original stock OS, then towel rooted it and installed CM (LOS 14.1 now), so I've no idea if this phone has always had this problem or if I caused it. It's not a big deal since I always keep my phone on but makes trying new ROMs scary. Has anyone heard of this before, or have any idea how to fix it?

HTC 10 hard bricks, no warning, won't boot or reset, totally dead

This is a strange one.
HTC 10 2PS6500, Android 8. Has been working fine. Today I took the phone out of the pocket, to find that it's been turned off. Strange, I know the battery was almost full, so it's not a power down due to low battery.
Tried to turn it on with the power button, didn't work.
Held the power and volume up + down at the same time, a few seconds later the phone vibrated and powered up. Battery at 92%. No sign of what might have happened. Phone was working. I wondered what happened but soon forgot about it.
A few hours later, I charged the phone back to 100%. While using it, the screen timed out, when I pressed the power button again, a message popped up saying "HTC recovered from an abnormal reset, send it to HTC" or something like that, and it tells me to tap it twice to send. I tapped it twice, the screen came up. I have the option of Send to HTC or Cancel. I pressed Cancel. The screen froze after that.
Buttons are unresponsive. I pressed the power and volume buttons to reset it, it went black.
Since then I have not been able to get it to respond.
Power button alone - nothing. Tried even holding in excess of 1 minute.
Power + Volume Down - nothing. Held for 10 seconds, 20 seconds, over 1 minute.
Powr + Volume Up + Volume Down - nothing. Held for different durations of time, no difference.
Connected it to a charger, no response, the light up top where it lits when charging does not light up.
It's completely unresponsive. No boot screen, no vibration, nothing at all.
Any idea what else I can try?
well some new development...
I was trying to do the hard reset on the phone periodically. Sometimes with the charger plugged in (but no light on top indicating it's taking any charge). A day later, I was doing another hard reset (not expecting it to respond) but it vibrates and boots up. Since then it has been behaving normally. Strange that battery was at 21%, when it was at 80% when the screen froze. I charged it to 100% then backed up the data while I had it on.
I got about a day of usage out of it, then while I was on a browser scrolling down on a web page, the screen froze again. Battery at 75%. After trying to reset it, the screen went black. Since then, no response on attempts to hard reset.
I have a feeling if I leave it alone for a day and try it it will come back alive.
Doing a search on the net yield nothing except I did see a post someone made saying after the screen froze had to wait till the battery drains 100%, then charge it back up and it will boot again. Is this what is happening? If it's bricked how is it consuming battery?
Anyone has any idea sure would like to hear it.
