Step 1

Decompile framework-res.apk, make sure you do this right.

Open /res/layout

Open keyguard_screen_tab_unlock.xml, replace all lines in your file with this line :

Save your file, navigate to /res/values

Open dimens.xml

Add / edit following lines :

<dimen name="keyguard_lockscreen_clock_font_size">[COLOR="Red"]91.0dip[/COLOR]</dimen>
<dimen name="keyguard_lockscreen_status_line_font_size">[COLOR="Red"]17.0dip[/COLOR]</dimen>
<dimen name="keyguard_lockscreen_status_line_font_right_margin">[COLOR="Red"]32.0dip[/COLOR]</dimen>
<dimen name="keyguard_lockscreen_status_line_clockfont_top_margin">[COLOR="Red"]27.0dip[/COLOR]</dimen>
<dimen name="keyguard_lockscreen_status_line_clockfont_bottom_margin">[COLOR="Red"]8.0dip[/COLOR]</dimen>
[COLOR="Blue"] <dimen name="keyguard_lockscreen_date_font_size">20.0dip</dimen>
<dimen name="keyguard_lockscreen_swipe_font_size">19.0dip</dimen>
<dimen name="keyguard_lockscreen_carrier_font_size">18.0dip</dimen>[/COLOR]

Red means edit the value to the provided value above.

Blue means add lines above.

If the line doesn't exist, add it !

Save your file

Next, open colors.xml

Add following lines :

[COLOR="Blue"] <color name="transparent_white">#66ffffff</color>
<color name="black_50_trans">#80000000</color>
<color name="black_25_trans">#bf000000</color>
<color name="lockscreen_date">#fff6f7c9</color>
<color name="lockscreen_carrier_swipe">#ffebebeb</color>[/COLOR]

Save your file.

Extract downloaded drawables.zip to drawable-hdpi folder

Compile your framework-res.

Step 2

Decompile your framework-res.apk again

Open /res/values/public.xml, but don't do anything. Leave the text editor.

Decompile framework.jar

Extract the smali in S3_WaveView.zip to /com/android/internal/widget, replace every existing file with the one on S3_WaveView.zip

Compile your framework.jar

Step 3

Decompile again framework.jar

Go to /com/android/internal/widget and edit WaveView.smali

Now, open back the public.xml you've opened.

Compare the IDs in WaveView with the one on public.xml

Make sure the IDs in WaveView is same like on public.xml

[B]new WaveView.smali[/B] [B] new public.xml[/B]
line 198. const v1, 0x10404f5 -> <public type="string" name="description_direction_left" id="0x[COLOR="Red"]0[/COLOR]10404f5" />

line. 306 const v1, 0x1080622 -> <public type="drawable" name="unlock_ring" id="0x[COLOR="Red"]0[/COLOR]1080622" />

line. 355 const v1, 0x1080620 -> <public type="drawable" name="unlock_default" id="0x[COLOR="Red"]0[/COLOR]1080620" />

line.404 const v1, 0x1080621 -> <public type="drawable" name="unlock_halo" id="0x[COLOR="Red"]0[/COLOR]1080621" />

line.453 const v1, 0x1080623 -> <public type="drawable" name="unlock_wave" id="0x[COLOR="Red"]0[/COLOR]1080623" />

If WaveView IDs are not same, change it but without the red parts (the red zero).

Done, compile framework.jar

Delete the framework-res folder.

Extras for S3 like clock-font :

Download the clock-fonts.zip, extract the content /system/fonts/

Done, enjoy modding !
