HELP!!! My MDA3's Power Button is COMPLETELY INOPERATIVE!!!!

Hi,
My MDA3's power button (on/off) stopped working!! Pressing the button does NOTHING!!! I had locked all keys except the power button, since the power button stopped working, the ONLY way i could turn device on was resetting it!!!!
I have tried upgrading ROM etc, but the power button still wont work!
Can anyone please help me with this?

How did you enter bootloader to flash the rom, is the power button not needed on the mda3 to enter bootloader.?

....
interestingly enough i was able to reset the device by just using the reset pinhole, even the hard reset they say by using recorder+power+reset i was able to do with out the power.

It sounds like you have a hardware problem rather than software, I'd send it back & get it swapped before the warranty runs out if I were you.
We've had four units fail with dodgy buttons, you might even find that it's one the other buttons that is stuck in the pressed position thereby preventing use of the power button (try the sound recorder/camera buttons).

..
I was able to fix this problem by opening the phone, cleaning it with compressed air and putting it back together. I suspect this fixed the stuck button somehow.

I had simmilar problem. There must have been garbage in the button, as I noticed that it did not have the same 'click' feel to it when it stopped working. Luckily my phone was still under warranty, and I swapped it out (ugh)

Touchscreen issues

I picked up my tablet from by desk this afternoon and the touchscreen stopped working. It does not respond to at all. I have rebooted it both via the power button and the reset bottom on the bottom of the tab.
One thing I have learned is the process on you tube where you set the rotation lock on and power up while holding the volmue + button does not work to do a hard reset. The button on the bottom only does a soft reboot.
I tried to re-flash the 3.2.1 firmware as well. I am currently waiting on a chat session with support. Boy does this suck, I may have to take back my old nook color from my daughter to hold me over until I get this fixed.
It looks like support is closed.
support: Hi, my name is xxx Joseph. How may I help you?
me: I picked up my tablet (a100) and the touchscreen stopped working. It does not respond to at all. I have rebooted it both via the power button and the reset bottom on the bottom of the tab.
me: The screen is not taking any touches. when I hit the home button the screen brightness comes back up. I can connect to it from my computer and see the data, also adb works.
me: hello, are you there?
me: Is there anyone there?
me: Thanks for the support or lack therefore of. If you are closed for the holiday you should close the chat support.

[Q] Touch buttons problems

Hi guys, I have a strange problem since yesterday morning: Touch buttons don't work anymore. When I press them it's like i press the bottom of the screen, for example if I'm in the home screen, pressing the "home" button will open the menu, and if I press the "search" button the phone opens the personalize menù. The phone didn't dropped (not recently as well) and the previous evening it functioned without problems, I played with games and all buttons worked. I've tried doing a factory reset, but it didn't solve the problem and it made the boot of the phone impossible (it stucked on the ROM splash screen endlessy) so I flashed another ROM through recovery but with no results, the phone works well in all of its functionality except for the touch buttons.
Can you help me with this problem? My phone is rooted so I'd like to not sending it to HTC for warranty reparation...

I'm afraid but that's the only option left for you to send to HTC because if it is a hardware problem and you waste all of your time trying to get the buttons working and you miss the warranty time then you'll just have to throw your phone in the bin

Major Catch 22 - Desire got Wet now have 3 issues! PLEASE HELP

Hi guys.
So i managed to get my desire wet/damp and whilst it still works it has developed 3 issues:
1) The weirdest of all - the phone wont go into standby, as soon as you press the power button or let it timeout the screen goes off and they instantly turns back on to the lock screen. If i leave it, it will timeout again on lockscreen and come back on, it does this forever. I have done factory resets etc, all the same. Weird right. As i result i would like to reflash the mod and see if that fixed it as assuming its software related (somehow).
2) Volume keys do not work - think means i had issues getting into recovery. Finally found a widget to do it and then....
3) Trackpad does not work in recovery so i cannot re-flash or try any new rom to see if that fixed (1)
Proper catch 22
Any suggestions appreciated.
Thanks

Install 4ext touch recovery.

Update after installing touch recovery
OK I HAVE AN UPDATE:
The plot thickens but i have managed to S-OFF my Desire and eventually install Clockworkmod Touch which obviously doesn't require me to use the trackpad button so I was able to use Recovery. I wiped the phone and tried reflashing the ROM i had been using (Insertcoin) but this made no difference, the phone still keeps waking up immediately that it goes to sleep (either with power button or by sleeping timeout).
So i decided to install a completely different ROM (CM10_VJ_4.1.2_v3.0) and this installed fine. Now the phone will go to sleep and stay asleep if I press the power button. Problem solved I thought!
Now when the phone is asleep 50% of the time, trying to wake it with the power button will cause it to reset immediately and goto the white HTC screen. When it restarted it sits on the unlock screen and keeps timing out, screen goes off, then immediately on again - weird. If i unlock and lock with power button it will behave. For some reason the Search key will wake the phone every time no issues. Only the power key to unlock causes it to reset. Phone is sleeping according to Battery info.
Any other suggestions for what I could try. Could this possibly be something hardware related now? If there a way i can log the key presses or reason it wakes/resets?
Any help really appreciated, the phone is pretty unusable with this reset issue now.
THanks

theres a few videos on youtube, if it was me i would take the phone apart and clean all round the buttons. mite solve it. But as it got wet, the water could of damaged something in around the trackpad r power button, hense always waking the phone.

Thanks mate. So i tried this and installed CM7 today and have discovered something. As i said above the volume down button doesn't work and the volume up only works with some persuasion. Once i installed CM7 the problem where I lock phone with power key and it instantly wakes up now persists (on the JB rom it at least stayed asleep but reset if power button was pressed again).
However whe i changed the display timeout to 15seconds i watched as it timed out and instantly woke then noticed the volume would increment down one notch each it woke up again. This leads me to think that rather then the volume down not working at all it is actually stuck down permanently and could be causing the issue here. Is there any way I can find out if this is the case and disable the volume keys through software or do i need to open up the phone and disconnect it?
Thanks for any help - i think we are getting there!

I actually worked out that the trackpad is being pressed down constantly too because on CM7 when i disable trackpad to wake the phone actually stays asleep. Stil the phone resets if i try to wake with power button though, must be something to do with the button combo being held down.
Is there any way to disable both volume and trackpad buttons at the kernal/system level?
Tried button remapper but does not allow to remap the trackpad press.

With a file explorer, go to
system>usr>keylayout and modify bravo-keypad.kl.

I'm just back from holiday where my Desire had a ten-minute swim in sea water!
Naturally it was stone dead when I remembered it was in my pocket as I waded across an inlet which was supposed to be ankle- deep but was over 1.5 metres in places
I thought there was no point in drying it out without first removing all salt so (minus battery and cards) held it under a tap for several minutes then left it to soak in tap water in the sink for 30 minutes.
I then dried it over gentle heat for a few days then tried the battery. The vibrator ran continually and the white LED flashed randomly but nothing else. After another two days drying it booted - but only into Fastboot and the vol switch didn't move the cursor. But after another two days - it worked almost perfectly! The vibrator is dead and the screen a bit streaky, but all the other sensors work just fine and it's quite useable.
I had been logging the hike using My Tracks and it actually shows the course going a short way into the sea.

do you have an assurance or warranty?
if yes-->change phone.

Thanks for this. I actually got an app that let you remap the keys but it does not let you do anything to the trackpad click button (which is now the one stuck down). See photo of whats in my bravo-keypad.kl file here:

Any other way i can disable the trackpad completely. Perhaps at the kernel level?
Thanks

[Q] Touchscreen only works in power menu?

Hello,
I just got a nexus 7 2013 that had a busted screen. It still showed data between the huge shatter, and didn't respond to my attempts to unlock it by swiping. I assumed it was just a bad screen and bought a replacement and installed it today.
The display worked, but the touchscreen didn't seem to be responding to me trying to swipe to unlock. I eventually figured out that although I couldn't unlock it, the dialogue menus from long pressing the power button did work! Well, some, anyway. I can change sound modes, airplane mode, and access the power off dialogue, but am only able to select cancel from the two options, though ok is not grayed out. I can also click anywhere outside the dialogue and it will back out of it, leading me to assume that the screen's hardware is intact and functioning.
I then hard reset it via stock recovery and am now at the welcome screen prompting a language selection with the big right arrow, unable to press it but still able to interact with the power off and cancel options of the power menu.
Recovery says its running KOT49H.
I've used NRT to reflash the same build from a stock download, and I'm still stuck at the same spot.
What the heck can I do?

I would assume that the new digitizer is still bad. There are lots of them on sale on Ebay where the seller would assure the merchandise has been "tested" before shipping. In reality, they might not be. If you happen to have one with spotty functionality, there's nothing you can do with the software to cure it. It would not respond in some areas, period. If you only replace the digitizer instead of the whole LCD/touchscreen assembly, chances are you have a partially bad one. I've never come across one good one myself.
