There is a lot of info about key combinations for boot modes, but all of them are either incomplete, wrong or do not clearly state which button is VolumeUp and which VolumeDown. I want to clarify this in a small thread.
Put the tablet in front of you, so the power button is top left. Now we've got the following modes:
Factory Reset - Hold power and right volume button - works?
Update from sd/update.zip - Hold power and left volume button - works
Recovery - Hold power and left volume button - ???
APX - Attach to PC and hold power and reset button - works, display stays off?
Some people state that it is important how to set the the screen lock switch. Is that true?
Could someone please add the info which of the volume buttons increases and decreases volume?
I am not sure about the recovery mode. Does it replace the update mode if TWRP or CWM is installed?

The proscribed method of pressing both up and down volume bar (while PDA is off) and then briefly pressing the power button doesn't produce the desired result.
Is there a programatical way of achieving this, please?
TIA

Try this, it may work:
Touch HD Clear Storage
You can also use Clear Storage to reset your device back to factory default settings.
1. On the Home screen, slide to the Settings tab and then tap All Settings.
2. On the System tab, tap Clear Storage.
3. Enter “1234” and then tap Yes.
I would check the buttons work then. I have used this method and it does work. Turn the phone off, long press on the power, yes to turn off. Then hold both volume buttons down, press the power button (keeping the volume buttons pressed).
When the boot screen appears you can let go of the volume butons.
Or use the clear settings above ;-)

I think the trick is to BRIEFLY press
the power button while keeping both
up and down volume buttons pressed.
Im pressing several different variations of Vol - + Power Maybe im doing it wrong?
Volume Down and Power button right? I feel Ignorant here this is the first android device i cant figure out how to get into recovery.
yes i have a proper update.zip on my external sd.
Thanks in advance.
Hold the Volume down key and then press and hold the Power key. Don't let go until you see the recovery screen.
I read to turn off your phone and press reset while holding power.
Hope this helps

Huh? Not even close.. If the OP wants to flash an update.zip, he needs to...
1. With device held horizantally, power button on top left, turn OFF the device.
2. Hold down the Volume - button (left side of the volume rocker)
3. Hold down the power button.
4. KEEP BOTH HELD DOWN until you see the Recovery text in the top left corner. This appears a second or so AFTER the Acer logo does.
5. Do not let go too soon or you won't enter recovery mode.
Hi, all.
After Android 4.2 update I can barely hear any sound coming out of my N7 speaker. I mean, literally - I have to put my ear next to it to hear anything (but there is some sound, just really quiet). With my headphones the sound is fine though.
I tried resetting to factory defaults, but that didn't fix it. I tried using Volume+ for increasing max volume, but that changed almost nothing.
What can I do?
Hi.
Did you try a hard reset, as described on google support ? :
######
If your tablet is on, power it off.
Press and hold Volume Up + Volume Down + Power until the device powers on. You should see an image of an Android lying on its back.
Press Volume Down twice, until the screen says "Recovery mode."
Press Power to restart into "Recovery mode." You should see an image of an Android with a Red triangle after a few minutes.
While holding down Power, tap Volume Up
Use the volume keys to scroll to "wipe data/factory reset" and press Power to select it
Scroll down to "Yes - erase all user data" and press Power to select it
Note: If at any point during the above steps your tablet becomes unresponsive, you can restart it by holding down the power button for several seconds.
#############
If that doesn't work, I (personally) would try to flash a factory image via fastboot.
If you don't know what this means or you don't want to do this, I would contact your reseller/google for a swap of the device, after you tried the hard reset above.

I'm not sure - does that differ from the factory reset that can be done in Settings? If not, I have already done that.
Well, give it a shot?
Is "power + volume down" is the way to simulate battery pull like other phones?. I tried it but it does nothing but making me press power buttom twice to start device.
Any info about this? or zen5 does not supported? I nearly can't find anywhere.
All I know about Power + Volume Down is booting to edl mode/download mode or something similar to that. I use Power + Volume down to reflash clean bootloaders using xFSTK (Fixing bricked Zen 5's). If you delay pressing volume down (pressing power first and press volume down as quick as you can before it vibrates) you can reach recovery mode. I think there isn't 'any simulating battery pull' in Zen 5. Only force power off. CMIIW
@ezrawk Got it! Thanks for your explaination.
HELP
My phone's power button is already broken so I can't turn it on using the power button. I tried to by using the charger and hold volume DOWN and HOME button and it takes me to download mode.
But I don't know why I can't cancel it by pressing volume down nor continue by pressing volume up. All I can do is holding volume DOWN, and HOME button again but then it takes me to blue android screen says "no commmand", then recovery mode shows up. So now I'm stuck at the recovery mode.
Can you help me find the solution for this problem?

Go to recovery mode and reboot to system
Have the same problem, power button stopped to work, when hold volume down and home button download mode were work, but volume up button do not work. Can only restart phone by holding volume down button for a while.
