[TUT] Change wakeup buttons

Challenge: don't wake up you phone when I press any of the buttons!!! Only ENDCALL button (example is from Samsung i5500 with Froyo)
Finding the keycode for a button
Click all the hardware buttons (write down the sequence you pushed
Find keycode with dmesg (rooted phone)
# dmesg|grep keycode:
dmesg|grep keycode:
<4>[ 6379.122037] key event (keycode:107, pressed:1), wlan_debug_step=0

<4>[ 6443.141397] key event (keycode:107, pressed:0), wlan_debug_step=0
So for Samsung i5500 the scan / keycode table looks like:
139 MENU
102 HOME
158 BACK
217 SEARCH
103 DPAD_UP
105 DPAD_UP
108 DPAD_DOWN
106 DPAD_RIGHT
232 DPAD_CENTER
231 CALL
107 ENDCALL
114 VOLUME_DOWN
115 VOLUME_UP
Which button definition file is in use
In a adb shell type: getprop hw.keyboards.0.devname
In my case it is europa_keypad0
cd /system/usr/keylayout
ls -l
-rw-r--r-- root root 349 2011-04-01 13:01 AVRCP.kl
-rw-r--r-- root root 1712 2011-04-01 13:01 europa_keypad0.kl
-rw-r--r-- root root 1697 2011-04-01 13:01 europa_headset.kl
-rw-r--r-- root root 1699 2011-04-01 13:01 qwerty.kl
This file looks like:
key 158 BACK WAKE_DROPPED <<<REMOVE
key 230 SOFT_RIGHT WAKE
key 60 SOFT_RIGHT WAKE
key 107 ENDCALL WAKE_DROPPED <<<REMOVE
WAKE: When this key is pressed while the device is asleep, the device will wake up and the key event gets sent to the app.
WAKE_DROPPED: When this key is pressed while the device is asleep, the device will wake up and the key event does not get sent to the app.
So:
- system needs to be r/w mounted
- adb pull /system/usr/keylayout/europa_keypad0.kl
- adb shell chmod 666 /system/usr/keylayout/europa_keypad0.kl
- edit you file, remove any WAKE or WAKE_DROPPED from the keys
that you don't want the phone to wake up
(or do the opposite if you like your phone to wake on a specific button)
- adb push europa_keypad0.kl /system/usr/keylayout
- reboot
Cheers

Plz any one help me.

How did you obtain permanent root? I've gotten almost as far as you have but I've had to reset my tablet after the first or second reboot after rooting.
Thanks!

I dont know if it would be of help.... I have a Ziio 7
Rooted it - and the menu/homescreen would not work....tried lots of work around nothing happened (deleting the google accounts etc..etc..)
Finally i did a factory reset....
my google applications stayed (market, gmail etc...)
Rooted again.. and now everything works....

[Q] switching tracks in the player the volume keys

Hi all!
Recently I was asked how to appoint a long press the volume buttons switching tracks in the music player. Something I have even happened,but it's not quite what I wanted to do. and so.

Now for a short press of the volume we will have to switch tracks in the player.
But that's not what I wanted to do. as I said,in this file does not set the values of action for a long pressed for example the menu button,or home. please help,I have looked everywhere but found nothing on how to assign a long press of the volume switch tracks?

Good work, and good luck in the future

[HOWTO] Fixing ghost-hardkeys

Apparently there are quite a few people having trouble with the hard keys (Menu, Home, Back, Search) becoming possessed, and pressing themselves at inopportune moments. For me it was the back key. Now on to the fixing.
First, the obvious. Root the phone, put it in debug (Settings>Applications>Development), and plug it into a computer with adb.
1) # adb pull /system/usr/keylayout/melfas_touchkey.kl key.kl
2) Open key.kl in wordpad, or nano, or vim. Hell, break out a hex editor if you want, just keep in mind notepad messes up the formatting. It'll look as such, though the numbers will probably differ.
key 139 MENU WAKE_DROPPED
key 102 HOME WAKE_DROPPED
key 158 BACK WAKE_DROPPED
key 217 SEARCH WAKE_DROPPED
key 232 DPAD_CENTER WAKE_DROPPED
key 108 DPAD_DOWN WAKE_DROPPED
key 103 DPAD_UP WAKE_DROPPED
key 105 DPAD_LEFT WAKE_DROPPED
key 106 DPAD_RIGHT WAKE_DROPPED
key 231 SEND WAKE_DROPPED
key 212 CAMERA WAKE_DROPPED
3) Because the 'Back' key (158) is pressing itself, and the 'Search' key (217) is basically unnecessary, we're gonna switch 'em, and render the 'Back' key (158) inoperable. Ex:
key 139 MENU WAKE_DROPPED
key 102 HOME WAKE_DROPPED
key 217 BACK WAKE_DROPPED
#key 217 SEARCH WAKE_DROPPED
Basically, replace the keycode of the faulty button (158) with the keycode of the Search button (217), then comment out the Search line (s'what the '#' is for).
So if it was your Home key, you would have replaced 102 with 217.
Sidenote: If it's your search key pressing itself, just comment out the Search line.
Now save the file.
4) # adb push key.kl /sdcard/key.kl
5) # adb shell
6) # su
7) type mount and find the line what looks like this:
/dev/block/stl9 /system ext4 ro,relatime,barrier=0,data=writeback,noauto_da_allo
c 0 0
we need /system to be writable, so issue the following command
# mount -o rw,remount /dev/block/(whatever it is for you) /system/
8) # cat /sdcard/key.kl > /system/usr/keylayout/melfas_touchkey.kl
Now just exit outta adb, reboot your phone, and you're done. Just press the search key instead of the back key (Or whichever was being rebellious).
P.S. If you end up really missing your Search key, I recommend the app "button savior".

great how to, saved me a trip to the samsung store.

Great post
Great post. my seach key is constantly pressing itself. do you think this file could be pulled with Root explorer, edited via the PC and then copied back via root explorer? I am not that good with ADB and command such.

Why yes pickupman66... this can be edited directly with root explorer. Make sure u mount the folder r/w then long press on the file and open in text editor. Reboot and no more ghost key.

Power button broken

Hi all,
I dropped the phone and broke the power button. I solved remapping the key with another that doesn't use much, and it works the problem there's when the cell goes into sleep mode because the current don't pass in keyboard, my question is: can I change the sleep mode and give current at one button or at kayboard and leaving everything else unchanged
someone could help me thanks a lot!

I'm not sure how it is setup on your device, but on mine there are two classes of buttons.
Most buttons are on the TWL4030 peripheral which uses a scanning matrix.
A few buttons are on the GPIO lines directly on the OMAP3621 processor.
Scanning is shut off in sleep mode, so scanned buttons won't work then.
The GPIO buttons can generate an interrupt and will work in sleep mode.
Since you know already how to remap keys, just look at /system/usr/keylayout and find what your options are.

the original situation in system\usr\keylayout is:
