Getting into recovery Mode no power button (resolved. Answer inside) - MTCD Android Head Units General

Hello,
I want to upgrade my unit from Android 6 to 8 but I have never been able to get into recovery mode with the buttons on my unit. I do have a reset, and I do have physical buttons, but I can hold the reset button and the lights never flash. I also dont have a power button, instead the knob, which I push it down is a mute mode. ive tried using the method between the reset key and mute knob with no success, I've also tried holding the reset key for 15 sec, 30 sec, 1 min. The lights never flash.
I tried the keyboard method, but it doesnt appear my keyboard is responsive until android begins to boot, the numlock key doesnt respond.
The keys on my unit are as follows:
Navi, Band, Menu, Mode, Knob for Volume, that knob pushes down to mute. The other side I have eject, track forward, track reverse, play/pause and a knob for tuning the radio/dimming lights.
Can I modify the mcu to change what the buttons do? Please help!

halp!

no one?

YES!!! I figured it out!!
I went into key study, changed the push button for the left volume knob from mute to power button. Then its just normal procedure. Hold down the new power button until it turns off. push it again for it to turn on and hold it down to go into recovery.
Hopefully this helps someone in the future

Manual Hard reset??

Is there a way to manually hard reset the TP2 w/o having to go into settings??
Please help!!
Turn off your phone completely. If buttons and touch screen become unresponsive, pull the battery out.
Hold both "send" and "end" button, then press and hold "power" button. Follow the on screen instructions.
for verizon
Hold down the end key till the device powers off, then hold volume down, send
and end till you see blue text on a white background. Follow hard reset prompt

I think this is for the At&t version below
1. Turn off the TP2. In my case, I had to pull the battery out since the on-off button didn't work
2. Press and hold the SEND and END keys simultaneously
3. While continuing to hold the SEND and END keys, press the POWER BUTTON (a bit of finger contortion here)
4. Press the VOLUME UP button

Hold the TALK, END, and backlight( on top of the phone) With the phone off till you get the reset screen. or if the phone is on then hold all 3 and use the stylus to hit the reset button till you get to the screen to reset.

[Q] Stuck at hboot - volume down button busted?

My htc desire is just over 2 years old. Out of warranty. Have not rooted or done anything else, just running the standard software.
A couple of months ago it got damp inside the pocket of my jacket. After turning it on it went to the hboot screen (the one where I can choose the options Fastboot, recovery, clear storage, simlock.) I dried the phone out and tried turning it on again.
Since then, whenever I have turned on my phone, it has had about a 50% chance of going to the hboot screen. Sometimes this screen would be unresponsive (ie. pressing the volume up/down buttons didn't do anything.) Sometimes I would be able to use the buttons to navigate around.
With a varied amount of removing the battery and mashing on the volume up/down buttons and power button when starting up the phone I could get it to start up. I think my success was related to half holding down volume up, so as to release the volume down button, and press power at the same time, but I'm not sure. This would sometimes happen after a couple of tries, but sometimes would take much longer, maybe half an hour of mashing.
Occasionally when running the phone would turn the volume all the way down to mute (as though the volume down button was being held, although I wasn't pressing anything.) Sometimes it would crash.
I took this to mean that my volume down button was busted, but things worked "ok" most of the time.
Today my phone will not respond to any amount of mushing the volume keys. I leapt into the deep end and disassembled my phone. I've pulled apart the volume button, removed the sticky black plastic that covers the circuitry of the button, removed the two small circular metal bits, removed the metal bar that is about 3cm long (1.5 in) and now the volume button is reduced to just a little bit plastic with copper bits printed on both sides.
I had hoped that this would be enough to completely disable my volume buttons and all would be well. Unfortunately... when I start the phone I am still at an unresponsive hboot screen
Does anyone have any advice that could help me? I could get the scissors out and start cutting stuff off but that seems like it would be unlikely to work...
Thanks in advance.
Wait...so you disabled the volume buttons, and you expect hboot to be responsive?
They were the only way to navigate through hboot.
What do you mean by "unresponsive"? Does the power button do something when pressing it?

Regularly, to get to hboot you hold volume down and the power button. My volume down button was permanently held down (I think,) so I hoped that by removing the volume buttons it would start normally.
By unresponsive I mean it goes to hboot but pressing the power button does nothing when I am there (ie. it doesn't select the highlighted option (fastboot))

Samsung Galaxy Epic display won't turn on...

I don't know what's wrong with my phone, but the screen display is messed up. Sometimes, the screen will display if I keep clicking the power button one-hundred times, but other than that it won't budge. Everything thing else works when I press the power button, the keyboard lights up, the home button and other buttons light, just not the screen. Like I said, I have to repeatedly press the power button so that in a slight chance, the screen might display.
I HATE THIS PHONE! What, do I do?

Need more info.
Can you access the recovery partition and it works fine? Access the recovery partition by powering on the device by holding down: Volume Down, Camera, and Power. Release when the hardware icons light up (down on the bottom: settings, home, back, search). You should see a menu appear after several seconds.
If the recovery partition does work fine have you tried a factory reset?
If it is still problematic within the recovery partition then it is more than likely a hardware issue. Possibly a problem with the power button?

HTC 10 Hard Power Off

Does anyone know how to force power down of the phone?
My phone is faulty and i need to mail it back to the seller. I cant use the screen but i need to turn it off before sending.
Pressing the power and volume down resets the phone, but does anyone know how to turn it off only?
Hold power + volume down to force the reboot, when the screen goes black keep the power button pressed and switch to volume up. This will reboot to the bootloader. Use the volume keys to navigate to power down and press the power button to confirm.
That should do it and all via physical buttons.
