Kernel that allows you to disable hardware buttons? - Nexus 6 Q&A, Help & Troubleshooting

Does anyone know if theres a kernel out there that allows you to modify/disable the hardware keys on the Nexus 6? I just bought a SnailVR headset, but unfortunately the harness presses down on all the buttons, causing it to reboot to the bootloader.
I've tried Xposed Framework and Xposed Additions but this key combination is hard coded into the kernel.
Any light on the matter would be greatly appreciated.
Thanks,
Grant

thats not a kernel that you are looking for, thats a hardware mod or an app that you need.

Thanks for the reply, but I'm fairly certain the key combination for rebooting into the bootloader is something I'd need to access in a modified kernel.
If this is something I can accomplish without doing so though, I'd be much happier with that solution. Like I said, I've used Xposed Additions which gives you the ability to rebind hardware key actions for press and long-presses. Unfortunately this does not disable the long-press action for rebooting the phone or booting into the bootloader.

This is not something you will be able to change. It is a safety feature that built deep into the system. Even if you disable them in the keyconfig files it will still do it. There are somethings that just cant be changed. You have to remember that not all the code for the whole device is available.

Thanks for the information. I appreciate it

That is correct. Pressing the keys for 10+ secs its hardware into the mobiles. Its like getting the battery out. Its there as a precaution if your mobile needs a hard reset. Nothing will be able to override it i think

Root the phone, install LMT Launcher and add qemu.hw.mainkeys=0 (to disable and hide the hardware keys) to the build.prop and reboot. A custom kernel is not required, it also works on the stock kernel.

(Wanted) Optical Sleep Wake

I am wanting to know if anyone can port the program for the nexus to the aria, that when the trackpad is pushed the phone will wake. I know that coming from an Iphone that is a huge benefit.
seconded.
it's a pain to reach over to push the power button every time because the phone slides towards if you if face up on desk pushing trackpad button much more elegant solution.
Hello, I am a new member and I thought I'd join and tell you what I found. I've been using my Aria for about a week already. I used lock2.0 (bugs and keeps your phone running idle, not standby), nolock (basically takes away lock all together and only wakes it up), this widget screen mode (bugs) thing and a couple others..
Anyways the best solution (in my opinion) is this app called "lockbot." It wakes the phone up using the trackpad and volume keys. The free version lacks the password but if you get the pro, you can add the pass code functionality (not for me especially if you need to do an emergency call plus you can always download a kill app in case your phone gets stolen). A good thing about it too is that you can modify your lock screens i.e. iphone style, x10 style, froyo style, etc. I got 5 different types cycling randomly. You can also change a few options i.e. lock during a call so you dont do a "face hang up" or shake to unlock. The only real bug I found so far was the x10 lockscreen because it would lag for about a second.
I know a few may say "oh the side keys will get hit and drain the battery" but honestly, after using the app for like 5 days, I haven't notice any change in battery consumption. Not wearing out your power button pretty much outweighs losing a minuscule of battery life.
Hope it helps. Of course you can try out the other apps to see if they suit you =)

I'm using lockbot now and it's exactly what I was looking for. I'll keep an eye on battery life and report back if it seems to drop.
Awesome suggestion, thanks!!
Btw I was going through the configurations. Apparently you can set a lock code for the lockscreen once you swipe it. You have to pay for the swipe lock but it's free to put in a numeric lock code.
Cheers
I tried lockbot and uninstalled it.
-It does not support the Aria's native resolution.
-Won't let you load BG pics smaller than the 480 x 846 or whatever the res of the device it was made for is.
-When you press the power button to lock and then immediately hit it again, it never locks, just shows the home screen again.
Would it be hard to port the N1's app? I just want something simple that works
nope
didn't work out for me.
almost locked me out of the phone.
I think it doesn't play well with task killer.
Im using an app called "no lock" disables the slide lock and you can jus press the optical button, volume or power buttons to unlock the phone.

This just became available on the Incredible...I am sending the file that needs to be edited to the dev who created it for the Incredible so he can make it work for the Aria as well. You can take a look at the thread here:

If anyone has access to the phone now and knows how to use adb you can pull the file off and send it to him. If not I'll send it to him later tonight.
Optical wake working for me
EDIT-Short Version...
-:Have Clockwork Recovery Installed and know how to use ADB:-
-DOWNLOAD ATTACHED qwerty.kl (may need 7zip to extract file from archive...)
-BOOT into CLOCKWORK recovery with NO USB PLUGGED INto phone!!!
-PARTITIONS>MOUNT /SYSTEM
-adb push qwerty.kl /system/usr/keylayout|adb reboot
END EDIT
First android phone! I love it. I too wanted optical press-to-wake, particularly because my ATT case made the power button a bit of a pain to press. First real post, been here a bit, I mostly just read/search.
Anyways...I had been searching around the file system getting myself acquainted with android and found /system/usr/keylayout.
It has 4 files in it, one of which is qwerty.kl. It sounded promising so I checked it out.
Long story short, I took a look at it, tried changing our DPAD_CENTER to WAKE instead of WAKE_DROPPED (just like the power button, seemed logical ), but it didn't work. Did some more searching and saw that the key was key # 272 on another phone instead of 232 in our qwerty.kl. I have it working now. Here's the thread I read to figure it out http://forum.xda-developers.com/showthread.php?t=729923
I did this in windows...(I have ADB working and Clockwork Recovery, you should get these too, invaluable tools)
1. Boot into clockworkmod recovery
2. Go to Partions Menu and Mount /System
3. adb pull /system/usr/keylayout/qwerty.kl (this pulls a file, qwerty.kl, and puts it in your adb tools directory)
4. Now you need to open the qwerty.kl file and edit it.
5. Use notepad, or notepad++, or vi, anything really.
6. Search qwerty.kl for key 232 DPAD_CENTER WAKE_DROPPED
7. Change 232 to 272
8. Change WAKE_DROPPED to just WAKE
9. Save the file
Now we need to push the file back to the device. This sounds very easy, and is, except I had trouble and got stuck in clockwork twice and had to pull the battery, as I think when I went to select reboot or unmount in clockwork (using the trackpad...), my newly changed trackpad was probably making everything act up. So I tried twice and had to pull batt twice before I just figured I would streamline my commands. (edit-trackpad works normally in clockwork after next step.)
10. do this! adb push qwerty.kl /system/usr/keylayout|adb reboot
This will push your new qwerty.kl file to the phone and reboot it without you having to use the trackpad which could leave you potentially stuck in clockwork recovery, thus avoiding the inconvenience of taking off your case/back.
I attached my qwerty.kl in a 7z archive so you hopefully can just extract it to wherever you need it and just adb push it to /system/usr/keylayout.
Good luck. Let me know if it works.
When the phone reboots you will be able to press the optical trackpad and wake the phone!
I haven't really tested it more than waking the phone a half dozen times but it seems to do what I want. When getting stuck in clockwork concerns me, I will simply edit my qwerty.kl file as needed when doing clockworkmod recovery work as it is a fairly simple and straightforward process.
EDIT-phone functions EXACTLY as before except can now wake via trackpad press!
Questions, why were you using the trackpad in clockwork?
Also, I like how no lock works since I have a security code on my device. When I dont feel like entering my code everytime the screen blacks out, I just run no lock and I wake the device up using the trackpad. Will your modification do the same? Or once I wake the device up, it will take me to the security screen?

Because I could...? haha. I think it did the same thing when i tried selecting with the power button as well, can't recall, and didn't futz with it enough to remember it today. Could be a clockwork error or my own...
This doesn't get rid of the lock screen, it just wakes the phone with a trackpad push which I believe was the original intent of the thread. "No lock," well...gets rid of the lock screen which is a different function all together. I don't use a code/pattern on my phone, just the standard drag down lockscreen, its not terribly inconvenient to me.
I find it a bit more convenient since my thumb is already there when I pick up the phone. Also, whenever I would demo my phone to anyone else (whether they owned an iphone or not) they would ALWAYS try to push the trackpad to wake it, and I would ALWAYS have to point them to the awkward power button.
I'm not a huge fan of installing random stuff, and this does exactly what I want. Simple fix ftw.

(Q) Can I turn off the deafening camera sound? (and others)

That'd be nice. Another few items that are still on the checklist include:
- Button re-mapper. I've used the search function here, but I've only seen this brought up in the context of other phone models and their custom ROMs. Is there a ROOT app that grants me Activator (iPhone) type functionality? I'd love to be able to hold-press skip tracks forward and backward.
- Something to instill confidence in the play/pause button on the stock mic headset. Sometimes it works as it should - other times, you have to press it twice, three times, hold it down, do a rain dance... I know the little guy's got it in him. I've seen him accomplish the feat, it just seems he might need a little encouragement from some ROOT app.
- I've searched quite a bit for this last one. Is there honestly no way to calibrate the S-pen? I do the little rubric that comes up when you dial the #14214# or whatever it is, as well as switching back and forth from right handed to left handed. There aren't any other more fruitful methods?
My ROM is the recent German LPY release.
Thanks guys!
If/when I don't want to hear the camera sound, I just turn the volume all the way to silent. Kind of silly, but I think there is some sort of stupid rule that says phones have to have that sound, so you don't take "bad pictures" of people or some BS.
Search Play Store for "Camera ICS"
It's based on the AOSP camera from 4.0.x but has the menu option of "silent mode"
You can also set the volume keys to be auto-focus and "shoot" for volume +/- so you could hold the phone in "reverse landscape" and have volume keys under right hand fingers then hold volume down then roll finger across to press volume up as well to take the shot? (that's how I have mine configured)
Great camera app! Thanks! No one knows of any fuctioning button remapping software?
u need to be rooted
then use ES File Explorer in setting enable Mount File System R/W
Navigate to
/system/media/audio/ui
rename Shutter_01.ogg to something else

Try touchscreen tune for note to calibrate spen (you have to register for a fee to make it stick, but you can test to make sure it works on your rom (requires root). If rooted, you can disable .ogg file as another suggested.

I just did a search for this and found this post here (as such I can also confirm what OP has said, and so I'm seconding this notion.)
To add to what OP stated I also would like to create Play/Pause by holding both sides of the respective Volume Buttons at the same time as well. Though I think for that to be done properly I would have to link this functionality to a music based app to prevent unwanted shenanigans.
Delete camera sounds at system media folder (you need root of course).
And replace your camera apk with this (without focus sound to made complete silent camera):

Change soft keys with gravitybox

OK I must be an idiot cause I cannot for the the life of me figure out where to change the soft keys in gravitybox. Can someone point me in the right direction.
Or if there is another app that's better I'm cool with other suggestions too.

I haven't used Gravity Box for a while since I have been using ART, but I have used SoftKeyZ Root. I think it's like $1 in the Play Store (link: https://play.google.com/store/apps/details?id=com.janis605.softkeyz), but it provides a number of soft keys that people have uploaded that are continually added to the app (or you can upload your own), it conveniently creates a backup of your stock keys when you flash new keys and it makes it easy to restore the backup if needed. That's my suggestion if you don't mind spending a dollar or if you have survey credit.
I tried softkeyz a while back and had all kinds of issues with my phone rebooting after I installed it. I have a backup and can try it again.
Under navigation bar tweaks. There's swap back and recents and option for cursor control with the keyboard open

[APK][LG-D415] LG-D415 QuickButton Editor

This little utility application is designed for assigning a custom action to the QuickButton on the LG Optimus L90 LG-D415. This application is only for LG-D415 devices.
After flashing a custom ROM we basically have a useless button on our device. In my CM11 ROM, selfless plug LOL, I assign a WAKE action to the QuickButton which, when pressed, will wake the device. So the button's not completely worthless. This application was obviously written for LG-D415 users running custom ROMs but it may, as in maybe, work on stock as well.
Anyway in response to a thread that was created recently and also after having thought about it previously, I decided to write this app.
The application is not signed and does NOT have any kind of advertisements. The only requirement is ROOT privileges as it must write to a system file. You will be prompted for root confirmation when the app is launched for the first time, this also depending on how your superuser is set up.
This application modifies, actually replaces, /system/usr/keylayout/gpio-keys.kl. The application will back up your original gpio-keys.kl only the first time you Apply a custom action. That way you still have your original file in case of error. The back up is saved in the same folder as "gpio-keys.kl.bk".
Have fun!!!
I used it. It works. The button now bring up my camera. D415

No, I dont think so, mainly because I'm having to use key ids that are pre-defined. I will dig in to it a little deeper tho.
Sent from my LG-D415 using Tapatalk
After some more digging I've determined that there is no way to define a custom application to be called by the QuickButton. At the moment, the only way I can think of to possibly do this is to have a background service running to "listen" for the QuickButton presses and then launch the appropriate activity.
In reality, at the moment in any case, all this app does it trick the system in to believing that the QuickButton is actually the button whose action we assign to it belongs to.
I also found two more actions I missed, "Search" && "Bookmark". Haven't tested "Bookmark" yet so I'm not sure what app it opens. LOL. Will know shortly tho
I've also considered adding "Home" and "Menu" to the list as well. Thoughts?
I like the ideas, I just really liked to set the button to open up my messages.
I really like the app though. Plain and simple.

Running stock, there is really no need for my application. As much as I hate to admit it, LOL. At this point in time, no, the only choices are they default apps I have already listed in the application.
I believe in order to implement the ability to launch ANY activity ( APP ), I will need to create a background service to listen for QuickButton presses and then act accordingly. This is still theoretical, but from my programming experience, seems to be the only answer. Granted, I'm a Windows programmer, so there may be something I'm missing or overlooking too. LOL.
Oops... Sorry folks, I made a boo boo with my last uploaded version. There was still an entry for "Bookmark" in the radio button choices. "Bookmark" doesn't do anything. LOL.
New version added to the OP
I may have found a way to allow the QuickButton to open "ANY" application. I'm in the middle, well almost finished, of another project. Once I get a chance, I'll experiment with my latest findings and will let everyone know
Will this work on Lollipop? I'm assuming so but just wanted to make sure before I Install it. If it does, that would be awesome because this useless button is bothering me haha. Either way, great work man.

Disable home wake screen?

Has anyone been able to disable the wake function by pressing the home key? The method I used for the note 2 (and which apparently also worked for the note 3) doesn't work. I tried editing the home key in system/usr/keylayout/gpio-keys.kl but it doesn't work. I also tried doing the same in qwert.kl...no dice.
