I've come across plenty of contradictory posts on many sites, so these are the actual procedures to access different modes for the hTC A9 - and possibly some other devices.
Starting from Power off.
download mode : VOLUME DOWN + POWER, release PWR when logo appears.
Starting from Power off.
bootloader mode : VOLUME UP + VOLUME DOWN + POWER
From these modes it is possible to select Recovery:
With VOL UP/DOWN highlight Recovery Mode and press POWER.
After the htc logo, when red triangle icon is shown, hold PWR then press and release VOL UP, recovery appears.
You forgot one, HTC FTM mode. Turn device off, then hold volume up+power for seven seconds

Tablet Hard Reset
I don't have experience with
this specific tablet, but many
Android devices use a similar
procedure.
Start with the tablet fully
powered off (not just in
standby). To force the tablet to
a fully off state, hold the power
button pressed for until it
powers down. This can take 10
to 20 seconds.
Hold the volume up button
pressed (some devices may use
the volume down button), and
then press and hold the power
button, until a small menu
appears. Release the power
button and then the volume
button.
Use the volume up/down
buttons to select the required
menu entry, and then tap the
power button to action the
selection.
I hope this works for you
Hello.
I have a LG 65 (D280n), and one morning I found it with blank screen (on).
I've tried all kinds of key combinations to reboot it or get it in recovery mode, without success: power on + volume up, power on + volume down, power on + home, power on + volume up + home, power on + volume down + home...
Nothing is working
Also, PC is not recognizing the device when plugged through USB (makes a connection sound, but that's all)
Any ideas as to how to reboot it/recover it?
Edit: I get the LG logo screen for a few seconds, then it flashes to black, appears briefly again, and goes blank for good (although the screen is black, it's on)
Hi,
I tried to root my phone by using the kingo root application, after 90% it just rebooted and now hangs in a boot loop.
I try to enter the factory reset mode, but when I press power + volume up it only vibrates. There is no home button on this phone. I also tried pressing all 3 buttons power, vol up and down, which just turned the phone off now finally, but I can't get into the factory reset mode. Also power plus volume down just reboot the phone.
//EDit: In case someone has the same issue: Power off the phone by pressing all 3 buttons, after that wait for 10 minutes then power on the phone by pressing power plus volume down until the android logo appears, stop pressing the power button and keep pressing volume down.
post can be closed.
UNIVERSAL RECOVERY BOOT GUIDEBy Zillinium
Switch Off the Device.
If you have Quick Boot switched ON, you'll need to remove the battery now.
While the Device is OFF & Battery is back in.
Press & Hold Volume Down
If you have a Home Key, Press & Hold the Home Key as well.
While holding Volume Down, And Home if supported, Press & Hold Power as well.
Now you should be holding Volume Down + Home Key + Power Key simultaneously, hold them all for approximately 5 seconds.
DONE !
PROBLEMS
Boot's into Download Mode = Use Volume Up instead of Volume Down.
BOOT LOOPS AND THEN BOOTS NORMALLY : Your holding the button for too long, it's causing a forced restart, try releasing the key combination immediately when the screen lights up, then hold it again.
1.Hold down the Power key for a short while to turn off the device.
2.Use the Micro USB in order to connect NOKIA to a charger.
3.After that start pressing Volume Down + Power key for a few seconds.
after above steps phone showing only charging
4. then keep pressing on volume down key, again press on power key till blank screen then immediately release power key only.
