I appears I have damaged the hardware volume buttons of my Shield Tab. I don't know exactly when, I suspect either when I unlocked it(it was working while I was doing the unlocking), or when I dropped it the day before that, but I know for sure it was working immediately after that.
I was living with it fine using an volume app, the shield controller and my bluetooth headset buttons, but now I'm in trouble.
I was trying to get it rooted, which I didn't do after I unlocked it. Now it will not boot. Lack of volume buttons makes it so I cannot fastboot the device with hardware.
Right now I am very lucky ADB is working when it's booting, but I am afraid to do anything at all to it, as if I loose ADB while it's trying to boot it will be effectively a brick without the volume buttons working.
I think I need to take it apart and figure out if the vol buttons hardware is the issue, or something worse.
Is there any teardowns of the Shield Tablet? How do I open it?

I haven't done anything with my phone yet other than update to Gingerbread, but I am curious about when the phone is in APX flash mode. Why do most of the tutorials tell you to keep holding the volume keys during the entire flash procedure? I had a phone with a similar low-level hardware flashing mode and as soon as it connected to the computer I could let go of the volume keys. I have seen a few youtube videos where people did not hold the volume keys and everything seemed to work. Was this just an urban legend that has taken hold in the G2X dev community, or will the phone disconnect from the computer if you let go of the volume keys? There seems to be no reason why once the phone is connected in APX mode you would need to continue to hold the volume keys. Has anyone in this forum flashed CWM or anything else in APX mode without holding the volume keys during the entire flash procedure?
Hmm not sure. I know with NVflash if i dont hold the keys the entire time, the bootloader fails to initialize. Maybe that is why?

So if you are doing a larger flash, like the OS restore, once the bootloader initializes you can probably let go of the keys? On my other phone it was an even lower level flash and the bootloader wasn't invoked, so that probably explains the difference.
I make sure nVflash, then I hold down the volume keys, and plug my phone into my computer. Once I hear the sound verifying that my phone has connected, I let go. It flashes fine for me.
I have a weird problem where the power and volume buttons don't work when the screen is locked. I know it is not a hardware issue because I had this problem for a couple days, then the power button started working again perfect the next day and now its back to not working. When the screen is unlocked, the volume keys work perfect and controls volume as it normally would. I downloaded some apps to enable the volume keys to work as an unlock button, but they fail to work.
As a last resort, I was going to flash a new rom to see if it would help, however when I boot into recovery mode, the volume keys don't work and i cant move up and down through the options. In addition, I've noticed that when I do a battery pull and put the battery back in, the phone automatically boots up as if the power button was held down.

Your power button is failing. It is a hardware issue. Send it for repair.

Do you have an idea of why the volume buttons aren't working though as an unlock button with apps tho? I also question whether it is a hardware problem because this has happened in the past before and then suddenly the power button works again perfect for months. It is just very annoying for me to sit here and hope for it to start working again.

It's a known issue that when the power button stay stuck the other buttons don't work. It sucks, but that's what it is. Nexus S always had this power button problem and usually you can send it to samsung to get it fixed. Some people have tried to fix it themselves without too much luck...
Ok, So my Shield Tablet has been great, never any issues until today. I was just browsing the web, gaming a few games, not installing anything or messing with system files are anything like that, and out of no where my power and volume buttons just stopped working! Heres the strange part though, they only stop working once the tablet is booted up. They work fine to power the tablet on from a cold boot, and they work fine in recovery mode (volume and power buttons), but one the tablet it booted the stop working. The only way to get the screen to wakeup once booted it by removing the stylus. To power down or reboot I have to use the terminal emulator, or hold the power button down for 10+ seconds to force a shutdown. Just pushing the power button once the tablet is booted up does nothing (it should either turn off the screen or bring up the power/reboot menu), same goes for the volume buttons, once booted they stop working. It has to be a software because the buttons work in the recovery. Has anyone else seen anything like this, and/or know how to fix it? I REALLY don't want to have to do a factory reset....
Never mind! I figured out what was wrong. I caused the problem and just didn't realize it. About a week ago, I was trying to use a ProEX brand Xbox 360 wired controller with my tablet using a USB OTG cable and for some reason the right thumb stick was being mapped to the trigger buttons. So, long story short, I copied all the info from the Xbox 360 controller map file in android and pasted/overwritten all the map settings in the Generic.kl file (which is what the ProEX controller was using for its mapping). By doing that, I basically accidentally removed the Power, volume up, and volume down key mapping because those keys are mapped from the Generic.kl file. I just didn't realize that's what caused the issue because it didn't take effect immediately. It only took effect after I rebooted the tablet several days later.
Also, this is kind of a double post, so if any mods would like to, please delete this thread. Thanks

Hello!!
So, here's the situation i've found myself in.
I bought a phone with a cracked digitizer, i bought a digitizer and replaced it.. however i damaged the volume buttons.
Booted the phone up and it fully works, however the person i bought it off used a password, which they didn't tell me
ADB is not enabled (cannot be enabled without access) and i have no way of booting to the recovery or fastboot.. the power button options are also only "power off" and "reboot"
How do i gain access? i dont mind the volume buttons not working.. i just need access to either the phone, adb recovery, fastboot etc....
HEEELLLLPPPPPPP
I'm not sure what rom it is (because i dont have acess), but its either android 5.1 or 6..
I had the same problem.
I solved it by buying new keys on Ali: http://it.aliexpress.com/item/Origi...11&btsid=a8e70488-46b6-4d42-a23c-c2e676bd2601
and welding them on the motherboard.
