Here are the key combinations for the existing A700/A701 Acer and their effects:
Definition
[Vol-] = button to decrease the volume, identified by two small black dots
[Vol +] = button to increase the volume, identified by a black dot
[Lock] = button to lock the screen rotation
[Power] = button to turn on the tablet
[Reset] = reset button to restart the tablet, located next to the USB port you need a paper clip to press it.
Boot into recovery:
- Press [vol-] + [power]
- Once the tablet vibrated, let go [power] and keep [vol-].
- Once the text that appears on the screen ("loading recovery kernel image"), let go [vol-].
Factory reset:
- Press [vol +] + [power]
- As soon as the tablet vibrates, let go of power and play several times [lock]
Fastboot boot mode:
- Press [vol-] + [power]
- As soon as the tablet vibrates, let go [power] and play [lock]
APX mode startup:
This mode is required to use the nvflash tool (not available yet)
- Press [vol +] and [vol-] (keep the pressure on both)
- Press [reset] once
- Releasing the volume buttons.
Nothing on the shelf says it is in this mode (black screen and LED power off), you must connect to the PC to make sure it detects the device.

I found this when try to repaired my friend's A701, i think this is very useful info, so i copy n paste here.
With JB there is a change on the A700 (can't test on A701):
Boot into recovery:
- Press [vol-] + [power]
- Once the tablet vibrated, let go [power] and keep [vol-].
- Now the tablet vibrates a second time, let go [vol-] and press [vol+] quick
- Once the text that appears on the screen ("loading recovery kernel image"), let go [vol+].

A701 Android System Recovery
Here's the A701 System Recover Mode, i just figured out.
Definition
[Vol-] = button to decrease the volume, identified by two small black dots
[Vol+] = button to increase the volume, identified by a black dot
[Lock] = button to lock the screen rotation
[Power] = button to turn on the tablet
[Reset] = reset button to restart the tablet, located next to the USB port you need a paper clip to press it.
Boot into recovery:
- If tablet is turned on, press [Power] for 5 seconds to shut it down.
- Press and hold [vol+] + [power] for 3 seconds
- Once the tablet vibrated, let go [power] and keep [vol+] for about 2 seconds
- Once tablet vibrated again, quicky press and hold [vol-] (for about 2 more seconds) until the third vibration to enter Android System Recovery
Use [Vol+] and [Vol-] to navigate, press [Power] to confirm command.

I just bought a non-new moto g3 that doesn`t starts. Before writing this I've made a search on this forum and try'ed to google a possible solution.
My cellphone problem is that when i press the power button appears the motorola logo then starts to flicker the logo of the android laying down with his belly open.
I turned it off and turned it on pressing the volume - and power button to enter on bootloader screen. Then I selected the recovery mode option, then appears the motorola logo and shows again the android layed down with his belly open. On this screen I tried to hold pressed the volume + button for 10 secs and pressed the power button.
My first question is: What do I need to do to fix it?
My second question is: I'm not sure if it has 1 or 2gb of memory, so I'll need your guys help to figure it out.
Follows the things are written on the bootloader screen (I hope this may helps)

i managed to boot into recovery this way:
- press and hold power and reset together for about 10 sec.
- release reset while still holding power
- release power after about 5 sec.
- after releasing power quickly press the power button again multiple times until the device boots up. It should direct boot into recovery mode
hope this works for you

Confirmed working on another KGL unit, thx
Not sure for KGL, but if it's a touch-only unit (no physical buttons) like my HA, it has a reset button on the front. Hold that in with a paper clip or whatever until all the touch-button LEDs flash a couple of times, then release it and press it in once more, just a press and not a hold. Not sure if your head unit has physical buttons though.
My Head Unit is brand A-Sure KM8W7 please help me access Recovery Mode.
Thank and best regards
Bro, peace be upon you...
I have ported the X OS 2.3 for my device running with the SoC MT6580 & the kernel is 3.18.35+
But, you know, if we press the power button, it will lock and if we press and hold the power button, it will show the power menu. That is switch off, reboot etc...
But when I do this, nothing happens and my device restarts !
How I can I solve this ?
