[Q] Can't get into fastboot with power+vol down

I tried to turn off the phone by by pressing the power button for 10 sec as directed in the guide on the development section. But all that did was restart the phone. So i turned it off with the regular method then tried to get into fastboot with power+vol down; But all the phone did was just boot normally to the stock ROM.
PS. I am trying to unlock the bootloader to install costum roms.
Thanks for helping

Go to settings > power > make sure "fast boot" is unchecked

Hope this helps!
Try that

I like to power down the phone then hold the decrease volume rocker then power on the phone. I've never run into any issues so this a pretty foolproof methodology in my experience.

Have You Tried POWER And VOLUME UP Buttons For At Least 10 Seconds? This Should Be Work.

Get into bootloader

The easiest way to get into boot loader while phone is on. I see a lot of people posting different ways.
Reboot phone, either by pressing and holding the power button until the touch buttons at the bottom flash or just by hitting reboot within your ROM.
When the screen goes black, hold volume down.
No need to press and hold both at the same time unless your phone is powered off.
The advantage being you can do this with just one hand.

Download quckboot. That's the easiest way if you're already rooted.

Ah but this also works if you cant boot due to bad flash or something!

As this looks to be meant as general FYI, the following should be noted:
1) Many people that can't get into bootloader, is because lots of people instruct to just "hold power and volume down". Which, if taken literally, doesn't actually do anything. You actually have to release the power button (after holding it for a few seconds), while still holding the vol down rocker. which brings us to . . .
2) You have to keep holding vol down until the bootloader screen comes up. Otherwise, if you release it too soon, the phone will just boot normally.
3) If you press the vol down rocker too late, the phone will boot into safe mode. You need to hit it before the HTC boot screen comes up, while the screen is still black.
4) There seem to be a good number of posts by folks that can't properly get into bootloader, and assume its an issue with the phone. But 99.9999% of the time, its just user error (not doing the button sequence properly). Just follow the OP, and the points I've listed above, and you will get into bootloader. If bootloader was messed up in any way (corrupted, overwritten, etc.), the screen would not come on at all. So the problem is not the phone, but almost always user error.
The one exception to this might be an obscure mechanical problem, such as the volume rocker not functioning properly. But this if almost never the case.

The only real time you have to hold both down at the same time, is if your phone is already off. Otherwise so long as you press and hold volume when the screen goes black from a reboot, you will get in.

That's the best way. Most ROMs have a reboot function built in when you hit the power button

As OP mentioned, this won't help you if you are stuck on the boot screen. Which is one of the more common situations where noobs suddenly realize they don't know how to get into bootloader.

I always just hold down both power and vol down until the capacitive buttons stop flashing then let go of power but still hold vol down until I get into bootloader. Works 100% of the time

[Q] Can't turn on my phone?

Hi,
I think I bricked my phone. I tried to root it using this guide http://forum.xda-developers.com/showthread.php?t=1583427
I installed CWM recovery, but when I tried to boot into recovery the screen left saying "Entering recovery.... This build is for development purpouses only etc..." Same after few reboots holding power button for ~ 10 seconds.
So I left my phone on that screen during the night, thinking maybe it takes some time to enter recovery
But in the morning the phone was dead and I can't turn it on.
The screen blinks for a second (see video here http://www.youtube.com/watch?v=bI-gy-hhXq0&feature=youtu.be ) and thats it. Holding Power, Volume down + Power doesn't help.
Any solution for this?

when you plug your phone to a charger does the red light come on?
you need to get into bootloader again. Saw your video, but what happens when: while holding volume down you press the power button for a second (while still holding volume down until bootloader starts?

Sometimes it does, sometimes it only comes on when i hold the Power + Volume down and goes off when I release Power button, bur then comes on again after a couple of minutes...

So if I read you right, you can get into bootloader? Reflash recovery, then flash a Rom and fastboot a boot.img

No, I was talking about red light. The screen doesn't turn on at all, just a short flash.

I don't know man, maybe someone else will help out here. Hold power button for like 30 seconds. You might have to send it in to be repaired.

[Q] How to shut this thing off(one S villeC2)?

This might be the stupidest quetsion ever but, I'm totally helpless.
I need to access the recovery, I flashed a rom which stucks at the boot screen, I need to flash another yet I cannot shut this thing of. I keep pressing the power button for 10secs, 3buttons starts to flash and screen goes dark. When I let it go, it restarts.
How can I power of this device without accessing the OS?

Hold it until the buttons stop flashing, about 20 seconds.

I keep pushing the button for way longer than that. Still it reboots.
Take a look

STOCK Update Help!

After realizing how much crud I had to do in order to unlock the bootloader and install the recovery and so on for this device. I decided not to and went for the AT&T Over The Air update.
I went to the settings, just like most phones these days, and did the "Check System Update" and what not, and after it did everything it needed to do, (Downloading, Installing, Restarting A Million Times) it finally ended up in a complete bootloop.
I've tried Factory Resetting.
I've tried using Zune.
I've even tried contacting AT&T and HTC, but no one will respond to me.
Can someone please help???
*No, I do not have warranty. It's an old phone I tried playing around with and obviously failed.*

What are your bootloader details? To boot into the bootloader there are two methods.
With phone powered on
Hold the volume down button, then hold the power button (so you're holding both buttons together), the button lights will start to flash, they will stop flashing and the screen will go blank, after a couple of seconds let go of the power button but continue to hold the volume down button until you reach the white screen with text, this is your bootloader.
With phone powered off
Hold the volume down button, then hold the power button (so you're holding both buttons together), after a couple of seconds let go of the power button but continue to hold the volume down button until you reach the white screen with text, this is your bootloader.
Please post the first five lines.
