(How-To) USE THE VOLUME DOWN KEY TO WAKE YOUR PHONE. (New Keys Remapped)

Credit goes to: Geniusdog254, Decad3nce, and BuglessPete for being remapping guru's.
Right, just slappin' this how-to together quickly before I go to work. I'll clean everything up and make things so that they're not so vague when I get home from work.
So if you're like me, and you hate having to reach all they way to the top right hand corner of your phone to press the power key so that you may wake your phone, then this tutorial will tell you how to make it so that your volume down key acts as a power key, which will give your Evo the ability to wake from sleep by pushing the volume down key. I've also remapped the search key so that it acts as the volume down key.
Please note that my remapping the volume down key will not effect it while in recovery, fastboot, or bootloader mode.
Make a backup of your supersonic-keypad.kl by running these commands via adb:
Code:
adb remount
adb pull system/usr/keylayout/supersonic-keypad.kl supersonic-keypad.kl
The supersonic-keypad.kl file is now in your AndroidSDK tools file, pull it out and save it to your desktop, just in case you ever want to switch back.
Download one of these files and save it to your AndroidSDK tools folder.
Volume down key acts as your power key & search key as your volume down key - http://www.4shared.com/file/c2KMz6tH/supersonic-keypad.html
Search key as select or enter -http://www.4shared.com/file/3ME8K6iK/supersonic-keylayout.html
Volume down key acts as your power key and search key opens up the phone application - http://www.4shared.com/file/-UaXzgwH/_2__supersonic-keypad.html
Then run these commands via adb:
Code:
adb remount
adb push supersonic-keypad.kl /system/usr/keylayout
adb reboot
And that's it, your volume down button will now act as your power button which will allow you to wake your screen, and your search key will now act as your volume down key.

Sweet find man..any chance for if somebody can attach the file onto this thread instead of sharing service?

attached.
You'll need to rename it to .kl

can someone make a flashable zip to do this please.

Nice thanks bro

This is a good hack. It'll give your power button a rest, as some owners were unfortunate of having cracks from the faulty strain.

Thanks mate.

NICE it worked. Now the VOL-DOWN key will wake phone up.
But you'll lose the volume down and you can't adjust the volume while in phone, so you have to get a volume widget or some sort.

but i like my volume down button turning my volume down and my search button searching

haha i agree with davebu. Nice feature though! I can imagine this will be useful for some people.

That's why I remapped the search key to act as a volume down key. A feature I find cool, seeing as the search key has done nothing but annoy me. Lol

Well then, I guess you're **** out of luck with this guide.
Although I've been looking into giving key 114 permission to run the WAKE_DROPPED attribute by editing init.rc. I'll look into that when I get home, or maybe somebody smarter than me can figure it out before then.

The other thing you could do...
The other way you can enable this feature is to download No Lock by BoD. It's an app that disables the lock screen, which I've always found kinda unneeded. It has the added benefit of allowing the phone to wake up upon volume button press.
Hope someone finds this helpful.
Enjoy!

Could you remap your "search" key to be like a "trackball press" on the HTC Dream?

Yes, but to my knowledge you'd only be able to use it to move in one direction. Somebody please correct me if I'm wrong.

He means can you make it so its the actual "Press" like when you press the trackball down and select something, not to make it so it moves around like when you move the trackball. Like a enter sort of fashion when you highlight over something with the trackball and press it down.

Good God, I'm slow. Thanks for the clarification. I'm pretty sure you could, but wouldn't it be easier to just use the screen to select or confirm whatever it is you're selecting and/or confirming? Or is there yet another thing in missing?

Yes, if it acted like a trackball click it would wake the phone.
I'd love that, but I think the issue is that the capacitive buttons are off when the phone is asleep.
Can anyone confirm this?

I was thinking it'd be nice for older apps that use a trackball press, like connectbot and spider solitaire.

I see. And yeah, you're correct about the captivate buttons. I think an easier route would be to edit init.rc to give one, or both, of the volume keys permissions to run the WAKE_DROPPED attribute. Although, making it so that one of the captivated keys could run the very same attribute would be better still.

Change Key Mapping

I've dropped my phone recently and the power button is now very finicky. Is there any way I can make the volume rocker work as a power button? Or what would you do?
Sent from my SGH-I897 using XDA App

Yes you can change the key mapping. The files are under /system/usr/keylayout I'm not sure which one exactly since it changes for roms. But you'd have to first go into recovery and go into advanced and perform a key test. Find out the key number of the volume key. Then in the keylayout file. Put that keynumber as the power button. I've never tried changing the power button, but it logically makes sense.

[HOW-TO] Survive with a broken power button

If your button is broken, your button is broken. Sorry . Some people have had luck cleaning it with electrical cleaner but unfortunately I was not one of them. Eventually, you will probably want to send it in somewhere to get fixed (you need all three hardware buttons for various development functions). But if you are like me and you just need a temporary fix (I'm happy w/ my current rom and will be upgrading soon), then read on!
So what you are going to want to do is swap your power and volume up functions by remapping their respected buttons. Alternatively, you could swap your power and your volume down, but I think it's more important to be able to turn it down (plus you can still take screen shots in ICS).
Here's how you do it:
You will need a file explorer (and phone for that matter) with root access. ES File Explorer would be my personal recommendation. Make sure you have root access turned on in the settings
You will probably start in /sdcard/. Navigate up one folder then go to /system/usr/keylayout. Here you will find all the files that control your buttons
For the physical buttons, go to "aries-keypad.kl" and open as a text in a text editor that your file explorer hopefully came with (if you can't in yours, use ES File Explorer)
Write down or take a screen shot of what you see so you always have a reference of what it should look like and won't need to keep checking here key 114 = vol down, key 115 = vol up, & key 116 = pow
Cut and paste POWER WAKE to key 115 and VOLUME_UP WAKE to key 116
Hit back to leave and save the file when prompted
Reboot your phone. You'll probably need to pull the battery since your power button is toast
That should do it. Your volume up button should now control your power and your power button should now control your volume up. A couple (not so important) notes:
I think you can accomplish the same thing by switching the key numbers and leave the functions where they are, but can't be sure since I didn't try it
If your button is behaving erratic and going off without you pressing it, completely erase the key and it's function from the file. After I used an electric cleaner on the button this happened to me. I tried leaving the key in there and assigning it no function but my phone went bonkers.
I have no idea if the number of spaces between the various functions and WAKE are of any significance lol. I would guess not but I kept them the same to be safe.
Some people may want to assign the search button as volume up. I'm guessing you could do it the same way but again, I haven't tried. The file cypress-touchkey.kl also has softkey functions but I'm not sure if you would need to play around in that one instead or possibly do both. If anyone has had success with this please share!
After editing the aries file, I notice a duplicate in there after reboot that has the old setup. In the file explorer it has the same name, but upon opening it, I can see that it is a .bak file. I'm 99% sure this is a backup that ES File Explorer has made for idiots like me that shouldn't be playing around in these files and need to revert
OK that's it. Sorry this got so wordy. I hope this helps someone!

Ye, but Volume wake + SearchToPower mod solves the same issue. I like to use my Search button for long Power press to access Power menu - it is supercool!

Another way to survive without power button is to install Super Manager and enable the 'Sensor screen wake' function. Simply wave your hand in front of the sensor to wake device, add a shortcut to lock screen.

remap volume buttons to power button - for people with broken power button Captivates

Hi every1,
I have a captivate with a broken power button and it was driving me nuts for the last 2 months since I couldnot wake up the phone if it went to lock screen. I tried no lock and other apps but they didnt work 100% of the time. Today I found this thread :
http://forum.xda-developers.com/showthread.php?t=850464
It is button remapper utility but it doesnot support captivate yet. However my only concern was to remap my volume buttons to power button.
This is how I did it :
Firstly, we'll need to pull the file that controls the buttons which is entitled "aries-keypad.kl" in "system/usr/keylayout".
To pull the file, connect your captivate and run:
adb remount
adb pull system/usr/keylayout/aries-keypad.kl aries-keypad.kl
Click to expand...
Click to collapse
Edit this pulled file like below :
key 115 POWER WAKE
key 114 POWER WAKE
key 102 HOME WAKE_DROPPED
key 116 POWER WAKE
Click to expand...
Click to collapse
Key 115 was VOLUME_UP while Key 114 was VOLUME_DOWN. I reassigned both to behave as POWER button.
After you're done with your edits, you'll need to save the file properly (NO .txt files!), and then you'll have to push it back to the phone.
adb remount
adb push aries-keypad.kl /system/usr/keylayout
Click to expand...
Click to collapse
Reboot your phone, and then check to see if the remapping works as expected. Your volume buttons should now behave as power button.
Simple and Effective!

Thanks for this, but I just have two questions.
Does this make us lose control of the volume using the volume rocker?
and
This change allows us to turn turn off the screen as well using the volume buttons, correct? Not just to power the screen on.

Yes you will lose volume control over which ever you choose. I personally chose to lose my volume up since i think it would be more important to lower my volume if i suddenly needed to. To answer you second question yes this function will work as an exact replacement for your power button meaning it turns the screen on, off, powers on and off, and would get you into download or recovery mode depending on the volume rocker you still had available.\
P.S. I did not change all options to the power key. I left the Key 114 VOLUME_DOWN the same.

oh alright. Thanks!
So I decided to go ahead and try this but I seem to run into a problem. I am able to pull the file through adb, but I can't seem to push it back into the phone. It gives me two errors: "operation denied" and "read-only file." Is there any way to fix this? If it matters, I am able to pull the file with having to do the "adb remount" step; idk if there is something wrong, but it won't let me "adb remount" either.
I've made sure I have all the su permissions so i don't what could be wrong.

You can edit the files on your phone using ES File Explorer.

If you install most asop builds there is usually an option under from control that will let you use the volume button to turn on the screen without losing volume cintrols . Works well too.

I don't mean to hijack this thread, but since we seem to have a similar problem, I figured you guys would have an answer.
How, if possible, are you guys installing custom rom since I really can't get CWM to work with the power button broken?

I'm using Root Toolbox to reboot in recovery, then using the home button for selecting things in CWM.

For example i remapped the power button to vol down. If my phone is off, can I power it on by using the volume down?

No you cannot. The remap only takes affect when android has booted. When the phone is off the power button is still the power button

That won't let you "sleep" the phone with the volume control button. My button is to the point where I press it sometimes it works, sometimes it brings up the power menu but most of the time it does nothing.

I use volume wake and an app called turn off screen. More inconvenient than power button but once you use the app once to turn off the screen it stays in your list when you long press the home key so I can turn off the phone without having to go the home screen every time.
Rip power button you are sorely missed.
I use rom manager to restart my phone into recovery for flashing.

I also asked this in another thread... I want to disable WAKE with power button...
I edited all . kl files in system > usr > keylayout and deleted WAKE on power button lines with no luck.

For those of you that this method did not work there is a much easy and hassle free alternative!! Takes a minute or two only!!
Get 'Go launcher' from the app market (play)
Get 'Go Locker'
Now Enable Go Locker on your device. And you are done!!
When the screen goes black again, Just press the volume button, The screen wakes up!!
Using this method you don't lose the normal functionality of the volume rocker!!
I respect the effort put in by "puneet_champ" to make this post.. I went through this post, I couldn't find a file named 'aries-keypad.kl' Good thing I didn't!
As a result of which I recalled that I used to have Go Locker on my phone, and that when I pressed the Volume key the screen turned on!!
At that time I found it a little annoying, But now it has turned out to be such a gift!!

The issue there is you have to have a custom launcher, and you can't turn your phone off yourself.

Samsung Galaxy S Captivate
Android 4.2.2
Kernel 3.0.66-g6c5dade
Cyanogen 10-1-20130224-NIGHTYLY-captivatemtd
I used both ES File Explorer and ADB method to try to edit the file to fix my power button issue.
Both methods allowed me to edit the file and have the edits remain after a reboot and reviewing of the file. However the edits don't seem to be doing anything as the volume keys still function as volume.
If anyone knows what I might be doing wrong it would be much appreciated.

^^^i had the same issue as you. No matter how I tried editing it to re map buttons it did not work. I trouble shoot this for many weeks and made no progress. A member did suggest making some custom scripts which was above my skill level. Ended up buying a new button. Actually just got the phone back fixed this weekend.

The file that you needed and you didn't find is probably not called aries-keypad.kl . Every sort of devices calls it a bit different, with keypad or kpd in the name of the file. For example the file on my device is called mtk-kpd.kl . You see?
Greetings, Plehai

Easier to use an app called button remapper and make the search button the power button. Volume buttons to wake.

[Q] Software Power Menu

Hi,
I'm looking for an app which can open the DEFAULT power menu.
There are many apps in the Play Store which CREATE a power menu, but I want one which can just open it.
I use power menu a lot and I'm sure most of us use it very much. I just want something which can prolong the life of the power button.
I'm currently using Screen Off and Lock from the Play Store which can lock the phone using an on-screen icon. I want something like that for the power menu too.
Any help would be appreciated.
Thanks in advance.

If you're rooted, you could try rom toolbox from jrummy, it has a complete rebooter section and a widget accessing to that section

I know there are apps which can display their own power menu.
But what I'm interested in is to use the default power menu...
Have a look at Screen off and lock in the Play store to know what I mean...

I assume you have a non-working power button. There are 2 ways you can do this:
1. Enable the Navigation bar feature in AOKP or SlimBean rom. Map the Power function to one of the button, but map it to the primary function of the button, not the secondary.
2. You can remap your capacitive buttons. Open the file /system/use/keylayout/cypress-touchkey.kl with the text editor of your root explorer, or copy it to your sdcard to edit it. Change KEY 217 ASSIST (or SEARCH), to POWER. Save the file and reboot. Also make sure you fix the permission of the file when you put it back if needed.
For both of these, press and hold that button to bring up the menu, one press = screen off.
