Hello everyone. I am new to the rooting community so i am not sure if this is possible or what, let me explain. I own a Kindle Fire first gen with android 4.2.2. Its rooted now with CyanogenMod 10.1.3-otter. My plan is to use the kindle for the head unit for my car instead of a cd deck.
EDIT: (well i cant post a picture of my project because i dont have 11 posts)
So what i need now is a way to power on the device without using the button, like a double tap on the screen to wake it up. Any info on how i could do this would be helpful, even if its not possible. Any other suggestions would be nice as well
Well knock On is a kernel-reliant feature. You will need a ROM or kernel that supports it (none that I know of for the Kindle Fire exist). You could keep the Kindle connected to USB power and enable the option in Settings->Developer Settings->Stay Awake to consistently keep the screen on. Otherwise I would suggest something to make the power button easier to press (perhaps a lever of some kind). Disabling the lockscreen is also a good idea for this kind of project (go to Settings->Security->Lockscreen->None). I'm drawing a blank otherwise because I always use my Kindle as a normal tablet.

I already have the lock screen off, not having the display turn off is really all i need so this helps a lot. The screen turns on when i start the car because of the charge then stays on. now i am using an app to shut off the screen. thanks tho, im just going to stop looking for knock on lol

Hello,
How can one distinguish between when the screen is off and when the phone itself is turned off?
I mean, with the screen off, a single press on the power button, makes it come back on again.
But when the device is off, a single press on the power button turns on the device.
I thought a long press would be needed to turn on the device, but a normal press is enough.
As a result, I can't distinguish between the two states and sometimes turn on the device when I would have liked to let it turned off because I did not remember if I turned it off already.
Thanks for your help
I had the same issue. No fix on the desire, but can download appreciate that helps......

Some roms have the ability to unlock with menu or trackpad button.
What rom are you using?
Yes if you are root the simple solution is to allow unlock on trackpad I use it myself, and it is very comfortable
I'm on the latest OTA ROM, non rooted.
I have heard of WidgetLocker, but without a way to try it, I'm not sure it will work nicely with the sense UI.
widgetlocker works, plus it has sense theme.

Have you tried calling your phone? This will definitely tell you if it's on or not.

Interesting, not necessarily convenient, but interesting idea
If you use a media player that starts the music once you plug the headphones.
Also plug it in an USB or an AC outlet.
I have seen far too many reports of this where people don't know how to fix this themselves. Just like any computer you need to know how to do a hard reboot or shut it down completely without ui input. Just like most computers it is very simple.
If your KF freezes our won't wake, do this: reboot it. Hold the power button down for 20-30 seconds, wait about 2 seconds, then push the power button once to turn it back on.
I hope this helps some folks as this procedure really needs to be common knowledge among anyone doing any kind of customization to their device.

Everytime im done with my Ouya, I go to the main screen press Y and choose "turn off ouya". I know that the ouya shuts down because the input on my tv goes blank and says that no source have been found. Now when I try to turn on my ouya,lets say about 1.5 hours later my ouya is already turned on and is asking me to shut down.
Why is this happening to me? Am I not shutting down correctly?why does the ouya turn itself on?

Wish I could answer, but at least I'm glad to know I'm not the only one running into this issue. I'll do the exact same thing to shut down, and notice my TV's input still shows active, I'll switch back, and it's asking to shut down Ouya / Controller / Cancel. I'll do the shutdown again, and then wait for it to show No Signal on my monitor. I hope this will be also be addressed by a future update...
When you shut off with the menu options ouya is actually going to a low power sleep mode instead of turning off - similar to a android tablet or phone when you just push the power button or close a case cover, the next time you push it it is an instant on instead of a boot process.
Apparently it failing to stay asleep has something to do with the HDMI interface, though I can't technically confirm or deny this I do know it's entirely possible.
The only way I've found to actually shut it off is to either hold the power button for a few seconds until it shuts off, or pull the power plug (not recommended.)
Or root, install QuickReboot and shutdown with it...

I am facing the same issue. I did changed the HDMI cable with some other one. this is weird:cyclops:

This actually works. Thank you.
Hdmi activity wakes up OUYA, many TV's scan inputs so they don't list them in "source" menu and this turns OUYA back on. A poorly thought out feature.
Rather than doing a hard shut down, you can do a full shut down by holding the power button for a full second or two. You will then get an on screen prompt to confirm shut down, this will do a full shut down not just put it to sleep like it does when you use the controller to initiate it. Constantly killing power to a running system will probably start corrupting files at some point.
There is also some sort of sleep or screen or keep awake option in advanced settings that is supposed to disable the hdmi wake up.

You can set the screen saver time in settings I have mine at 15 minutes. But after 30 minutes of inactivity it will shutdown. it's really just a deeper sleep then a full power off.
I set my screen saver to 15 minutes (or whatever the lowest is) and then it turns off 30 minutes after screen saver pops up.
It wont turn off if you are in a sideloaded app though like cable tv or xbmc so I always make sure to just hit the home button when I am done using it so it turns off.
Does it turn of if your downloading an app.

This is bad news for me, I want to buy fire TV mostly for XBMC, I use it at night and will just have some TV shows play, I set a sleep timer on my TV to shut off automatically, the Original XBOX i'm currently using has option to shut down after x amount of idle time inside XBMC. Does anyone know of a way to make XBMC app close after certain time frame has passed? I wouldnt want the fire TV to be on/not sleeping ever 24/7
Have you experienced with sleep option on xbmc I have not tried it yet with the Fire TV. Not sure if it just exits xbmc when it reaches 0?
Another option would be to see if SleepTimer can be sideloaded on Fire TV. Not sure if this would work on the Fire TV but you could set to exit your "music" app after a certain amount of time and just set XBMC as the music app.
I'm having an issue that I haven't sorted out yet where it won't seem to sleep even on the default home screen when I have my USB XBox 360 controller plugged in. This happened before I sideloaded antyhing too, and I thought it might be of some help if there was any USB device that may be preventing sleep for someone here too.
would it be possible to do a real shutdown with root?
Pressing Fn+Esc on my Logitech K400 puts it to sleep immediately.

I've been able to do a reboot over adb but I'm not sure if there is a shutdown command. With root I'd assume we'll be able to shutdown pretty easily.

That's awesome news! I'll try it on my wireless keyboard too and report back (if I remember to )
not sure if everyone knows but, holding Play/Pause and middle select button for 5 seconds, turns it off.

You sure? Mine just restarts.
I don't think it ever turns off completely. The light will go out, but if it was 100% off you would have to unplug it and plug it back in to get the control to work. There is no off switch.
Mine restarts as well. Only way I have found to turn it off is to unplug it.
Mine turn off with the combo yocoldrain mentioned, it shows a message of turning off. Thanks

What software version do you have.... as version 51.1.0.1 say shuting down but then actually reboots.
Don't be concerned with the fire TV staying on when not in use, your tv uses more in standby power mode than the fire tv uses in full power mode.
The box is made very well, all that weight comes from cast aluminum, the whole case is one big heat sink.
before and after new firmware, box still turns off on my side. well it says powering off, then amazon logo comes on as in its restarting or something, but actually turns off.
Hours later, I can still see it polling for the remote's battery state. It never really turns off. That's probably for the best, user experience wise. You wouldn't want to click the remote and have absolutely nothing happen.

yes, get elmerohueso screensaver, he nicely enough updated it so even if you left xbmc paused, it will stop the video, and initiate suspend. my firetv is always sleeping now
I used to turn off power for any unused devices, even it takes only few watt. There is no menu to shutdown and turn off fire TV before I cut its power. I'm wondering whether it is safe to cut its power at any time. Or it's not necessary to have a menu selection to shutdown system? Thanks.

It should be safe to just unplug, but if you use it often eventually it could cause a problem either in the firmware or the the connection itself. A simple solution would be something like a Woods wireless remote outlet. The one I have comes with 3 plugs and a remote with a switch for each. The plug can take a bit of room on the surge protector but so does the FTV power cord. I just press and hold the select and play buttons on the FTV remote for about 5 seconds and when the screen goes black I hit the power button for the outlet.

Get a Microsoft remote (MCE Remote). The power button on the MCE remote will put the firetv back to sleep. When you hit the power button again it turns back on, or hitting any button on the firetv remote.
I actually prefer the MCE remote because it offers more function when using XBMC and VIMU. I can actually time skip vs ffwd, hit stop, etc... Only complaint is there is no home button. The microsuck button does not take me home, and I have not figured out how to program it on the MCE remote.

As i've stated in another thread, "sleep" on this is pretty much the same as sleep on a regular android device. It's still fully awake, although the CPU might be downclocked a little.
As for home, you need F12 to get home.

I love low watt setups, so I know the mind set for the OP. It would have been nice to be able power off the device! I was told that lab126 felt the footprint was small enough in standby that it wasn't needed. They also wanted to be able to update when not in use, etc...
You could hook it up the ftv to a power strip. I've seen power strips that have one active outlet and shuts off the rest of the outlets when the primary device is not used. That could be another option?
Rbox- Do you know where the MCE remote values are stored in the FIreTV. I want to see if I can modify so the windows button is f12.

Since it shows up as a regular HID keyboard I don't think it has a keylayout file. What I do know, is that the kernel could probably do it. The HID layer has a quirks system that allows you do to funky stuff for individual HID devices. Do you know the usb vendor and device id for the remote? I can take a look at the quirks stuff tonight and see if we can do anything. It might have to wait until custom kernels can be loaded though.

I'm at work but I can pull the HID/Device info when i get home tonight. I will PM you the info, so we're not clogging the OP's thread.
It takes 3 to 4 watts to stream a movie - measured on a Kill a Watt meter. I forgot what the reading was on sleep mode but its not much. The max watts I've seen was 5 watts and that's while installing an app.

What gen is it? I heard old mce receivers don't work? My USB receiver is a Phillips/nxp. It came with my zotac mini pc.
I just got my fire TV, rooted and installed a few apps including the firedtv.
I left it over night and realized it never went into sleep (the front led was on). I was able to put into sleep using a keyboard, but I don't want to keep the keyboard near my fire tv all the time.
Do you guys know what is wrong?

Try rebooting your box and without loading any external apps, see if it goes to sleep after a certain time. My guest is that an app is still running in the background preventing sleep mode.
When I first installed XBMC that happened too. I found out that XBMC was still running in the background because I didn't properly exit the app. Clicking the home button on the remote just leaves XBMC running in the background. Exit by pressing XBMC power off button and setting the system power saving timer to shut down at a interval during idle works.
