Change Key Mapping - Captivate General

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?

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.

Volume up/down don't work correctly anymore

Hi,
My Touch Pro's volume buttons suddently aren't working correctly anymore. When I press one of the buttons, the volume screen is displayed correctly, but when i press the volume up/down key, the volume doesn't go up/down, instead it works as an arrow up/down on the currently running program.
What can I do to restore the volume keys function?

Bump - no one with an idea?
Sounds like you have remapped its function either with a mapping app, tweaker or reg edit. Basically undo what you did to get back to "normal" operation.

[Q] Remap Buttons?

Hello,
I have a friend with a Droid 2 and their power button is on the way out. Is there a way to remap the camera button to be the power button?
I have tried editing the "cdma_droid2-keypad.kl" file, but it doesn't seem to change anything...
Code:
key 116 POWER GRAVE
key 211 FOCUS POWER WAKE
key 212 CAMERA POWER WAKE
does this code look correct? I just can't seem to get it to change anything. After pushing the file it doesn't change the button behavior at all.
They are rooted and on CM7

[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.

Nexus S 4g - Disable broken power button?

I've already read through this thread: http://forum.xda-developers.com/showthread.php?t=1596085 and used this thread http://forum.xda-developers.com/show....php?t=1524858 for remapping my search button to my power button, along with using volume for wake. I have done both of these, and that works just fine.
But, my problem is a little different.
My original power button didn't just stop working, it is actually malfunctioning. Meaning that the power button is being hit at random times, even when I don't press it (or the search button which is now my power button). It is extremely annoying and difficult to use the phone.
Does anyone know of a way to disable the power button completely? I'll settle to using search for off and volume buttons for wake, but I need a way to disable the original power button. The button remapper app from the thread above includes a way to remap or disable every button, except the original power button.
Thanks for your help
It says it all in the second link you posted. Read it all.

No.
Like I said, I want to DISABLE the power button completely, because it's malfunctioning. I have ALREADY remapped it to the search key, but the original power button keeps pressing itself, turning the screen on and off, bringing up the boot menu, etc.
The button remapper app allows you remap or disable every button EXCEPT the power button. So while you can remap search to be power, you couldn't remap power to be search (or in my case, disable power completely).
Anyone?
You would have to physically disable the button yourself.
I don't think its possible to fully power off your phone, but what you can do is map the volume up or down buttons as a wake key. I myself want to do this and am still searching for the solution, but if you want to take a crack at it:
The file buttons you want to edit should be in here. somewhere(system/user/keylayout) Root explorer can help you edit the layout without changing the format. That's as far as I can take you for now
