A modder called JizzMoto originally made this guide. Its really easy to follow, an it brings great bonuses. Please read this guide, and make the proper backup of the 005b_0001 SEEM with P2KMan, since some peeps dont get this mod and want to go back to the way it was....
First, you'll need
P2K Menu Editor
Now,
Connect your phone, then go to the Phone Key Mapping section (under the Tools menu).
A window appears. There, click Open SEEM>From Phone
The map of the phone keys appear. Click on the Voice Key (at right side of the phone) and select a new key value:
Joystick: Fire (Middlebutton)
After that, click on the Smart Key (on the left side of the phone) and change the value to:
HeadSet Default Smart Key
Then, change the Volume key: Higher Volume to:
Joystick:Right
Click on Save SEEM>To Phone and restart it.
That ends part 1.
Now, lets edit the mma_ucp file. Open it (click on Open Menu > Open from phone)
Next, add Shorcuts to the main menu. Be aware that this must be in the fifth position for this to work correctly.
Do this and save the mma_ucp (Save Menu > Save to phone)
That ends part 2.
Now, its time to add the menus. I've tried addig PhoneBook, Photo Camera & Sounds. The original creator calimed he used it to acccept BT transfers (dont know how, never could myself

)
Select the option and press the middlebutton for a few seconds. The phone will ask youf you want to save this as a shorcut. Say YES.
After saving it, close the flip, and try it out. Press the right key you modded earlier twice, this will get you into the menu. Now, press the upper left key you modded to ove around the menu. press the right menu key again to enter the desired option.
To make a call, highlight the contact ad press the right key. To end it, keep pressed the lower key (acts as the red button, hold it to end a call, exit a menu....)
TroubleShooting & FAQ
Now, there are some things to be considered:
- You cant lower the volume normally.
FIX: Press Higher volume key (the only key you didnt mod to the left) and then, to lower it, press the desired volume level with the numeric keypad)
- Lost the outside Voice Key function
FIX: you can remap another key to do the job, like the Browser button.
- The phone restarts when i try to ge tinto some menus
FIX: Not all menus are supported. Normally, the ones that work best are the ones without icons.
- Can i change betwee ringstyles normally?
FIX: Kinda. Press the middle left key and then the upper left key to change between them.
So, hope you enjoy this as much as i do.
