[guide] remap headset button to work with ultra

Hi Guys,

Sorry if this is a re post or someone else has come up with a better alternative. Hopefully then a moderator will clean this thread.

As most of us have just migrated to ultra from different models, we may have a spare headset laying round. The issue here is most of the headset is just not compatible with ultra i.e the buttons don't function as we want it to. This is a guide that may help solve that problem getting the best out of our old headset or the ones from different models

These are the steps

0.MAKE BACKUP OF SYSTEM!
1. root
2.Install THIS
3.Plug in your headset, open Key test and click any button
4.Note down scancode. In my case it was 257
5.Browse to system/usr/keylayout/msm8974-taiko-mtp-snd-card_Button_Jack.kl (use rootbrowser)
6.search for HEADSETHOOK
7.change the key to what ever scancode gives i.e 257 (in my case) . It should look like this

#original: key 226 HEADSETHOOK WAKE
#changed: key 257 HEADSETHOOK WAKE

8.now change the scancode number, in my case key 257 to 226 (or the key HEADSETHOOK is assigned to)

#original: key 257 VOLUME_UP WAKE
#changed: key 226 VOLUME_UP WAKE

9. Install THIS
10.Reboot
11.Configure buttons as per your wish

Hope its helpful.
