Phone died - HTC U12+ Questions & Answers

Was charging my phone and I saw it had a fb notification. As I clicked on it, the phone froze and then shut itself down after 10 seconds. Now the charging LED doesn't come on when plugged in and the phone won't boot up anymore. No combination of volume keys or power button does anything. When I plug it into my computer, it is recognized as "QHUSB_BULK" and won't let me access it in any way.
Any ideas or is it time to just bury this phone and upgrade?

Phone entirely bricked. Won't turn on, won't charge, nothing.

I was taking a video, and finished it, when suddenly the phone froze up and turned off. I've been using MIUI, and while it's mostly pretty stable, reboots and crashes happen, so I just rolled my eyes. But since then it's been completely dead. I couldn't turn it on, even after taking the battery out several times, can't put it into recovery or download modes, and it's been connected to the charger for about ten minutes now and still nothing.
I haven't flashed anything for ages, haven't done anything odd with the phone at all, I have no idea what could have provoked this. Please help, I can't imagine what I'd do if my phone was permanently dead.
Samsung Galaxy SII with MIUI weekly ROM (currently 2.4.27)
Things I have tried:
Long press power button to turn it on (obviously)
Same thing after taking the battery out for ages
Press Vol up + Home + Power to put it into recovery
Press Vol down + Home + Power to put it into download
Plug it into charge
Plug in data cable connected to computer
Take out battery for a while, then replace, plug data cable into computer (but not phone), hold volume buttons while plugging in phone (internet guy told me to)
Everything above shows absolutely nothing on screen. Charging heats it up a little.

[Q] xperia z3 not respondig

hello,
I had left my phone to charge at night, then this morning it was not responding. Power button was not waking up the phone. Then i forced to reset by power and volume buttons. Vibrated 3 times and completely shut off. Now it is not opening.
I already tried, reset button in sim cards slot. It is not working also. Please help me.
Did you try connecting it to PC Suite or FLashtool? Check that once and also try charging another hour and then force reset the phone. Also I think there is a reset button somewhere under the sim card slot. Try that one too.
Hold volume up and press power. Wait for beep three times. Give it a few seconds and then press power alone, should boot.
Thanks guys, i tried both but still i have sudden death. reset button and power+volume buttons not working. Also flashtool could'nt find my device.
Thats not good, any led when plugged in?
I had a similar instance after flashing unofficial cm12. Phone was cooling down from taking a run through an obvious cpu bug that really killed my battery. I shut it off to cool down with 20 precent still left in the battery. And the phone started to act this way when I went to power it on. No led power indicator or anything even with usb connected. My computer did respond to the usb being connected as if a device was there though. I waited about 10 minutes with the phone in front of some cool air and then did the volume up power button reset which worked then. Still quite a scary incident.

[Q] One S wont charge or turn on

Woke up one morning and the phone was stuck on the startup screen. Turned it off, and when I rebooted, it still was stuck on the startup screen. Then, after a day or two, it would not reboot at all. no red light when plugged in charger. also when its plugged to pc, pc is making sounds like its plugged and then unplugged many times. is it possible to fix it? or its dead motherboard?
Are you able to access the bootloader?? By pressing volume down and the power on button simultaneously while no cable is connected to the phone?

[Help] Huawei Y520 keeps vibrating, no boot

My phone Huawei Y520-u22 doesn't boot up. If you plugged in in a USB, any usb with power like from computer or wall charger, it just keep vibrating, even if I removed the battery.

I already tried Botting it in Recovery or Fastboot but it won't.
I already tried opening the phone and cleaning the power button and tried also the brutal clicking the power while usb is on.
Im short, ifnthebvibrate doesn't stop during thenusb plugged in,I cant do anything.

2n Gen Moto G Boot Loop / Won't Start HELP!!

I have a 2nd Gen Moto G that was pretty much in mint condition & prior to yesterday it showed no signs of any potential problems. Then last night the screen completely froze & wouldn't allow any input. The phone then shut itself off & I figured it would just restart & be fine. Instead it went into a constant boot loop where it reaches the white "M" animation screen then shuts right back down. I played around with it for a few hours today & did a ton of searching on the internet with no results.
I also should state that the battery did not die when this happened. I mention that because there were some posts where people let their battery go completely dead then they couldn't get their Moto G to power back on, however that was not case for me as the battery had well over 50% charge when this happened.
Things I have tried in order to fix this:
Using a different charger (both wall and USB to the computer).
-Holding down the power button for 7-10 seconds while plugged in.
-Holding down the power button for 7-10 seconds while not plugged in.
-Holding down the power button for 2 minutes or more (while plugged in and while not plugged in).
-Holding down the power button and volume up buttons until the phone starts (while plugged in and while not plugged in).
-Holding down the power and volume down buttons for 2 minutes or more (while plugged in and while not plugged in).
Now this step does bring up the fastboot menu however selecting any option in this menu just causes the phone to back into the boot loop. And yes I know how to access options in this menu (down volume to scroll & up volume or power button to select).
So basically everything just sends the phone into boot loop. Is the phone toast? Also I should mention that all day today it would randomly try to start itself & get to the Moto animation screen & then shut down & that was while it was sitting on the desk & I hadn't even touched it.
If the phone is toast is there any way I can access files like pictures by plugging the phone into my computer while the fastboot screen is up?
Alright so seeing as no one has any suggestions (understandably) & based on the searching I've done I'm assuming that the phone is just DOA. However does anyone know a possible answer to my second question which is, if the phone is un-savable is there still any way I can access files like pictures by plugging the phone into my computer while the fastboot screen is up?
