HOW-TO:


Volume Steps:

1) Open framework.jar.out\smali\android\media\AudioService.smali

2) Search for

Code:
array_0
It will looks like this:

Code:
    .line 205
    :array_0
    .array-data 0x4
        0x5t 0x0t 0x0t 0x0t
        0x7t 0x0t 0x0t 0x0t
        0x7t 0x0t 0x0t 0x0t
        0xft 0x0t 0x0t 0x0t
        0x7t 0x0t 0x0t 0x0t
        0x7t 0x0t 0x0t 0x0t
        0xft 0x0t 0x0t 0x0t
        0x7t 0x0t 0x0t 0x0t
        0xft 0x0t 0x0t 0x0t
        0xft 0x0t 0x0t 0x0t
    .end array-data
3) Change f (15) to

1e (30 steps)

or

2d (45 steps)

It should looks like it:

Code:
    .line 205
    :array_0
    .array-data 0x4
        0x5t 0x0t 0x0t 0x0t
        0x7t 0x0t 0x0t 0x0t
        0x7t 0x0t 0x0t 0x0t
        0x1et 0x0t 0x0t 0x0t
        0x7t 0x0t 0x0t 0x0t
        0x7t 0x0t 0x0t 0x0t
        0xft 0x0t 0x0t 0x0t
        0x7t 0x0t 0x0t 0x0t
        0xft 0x0t 0x0t 0x0t
        0xft 0x0t 0x0t 0x0t
    .end array-data
4) Recompile back



Smooth Scroll:

1) Open framework.jar.out/android/widget/AbsListView.smali

2) Search for

Code:
.method private createScrollingCache()V
Code:
.method private createScrollingCache()V
    .locals 2

    .prologue
    const/4 v1, 0x1
3) Change 0x1 to 0x0

Code:
.method private createScrollingCache()V
    .locals 2

    .prologue
    const/4 v1, 0x0
4) Search for

Code:
.method private initAbsListView()V
Code:
.method private initAbsListView()V
    .locals 3

    .prologue
    const/4 v2, 0x0

    const/4 v1, 0x1

    .line 824
    invoke-virtual {p0, v1}, Landroid/widget/AbsListView;->setClickable(Z)V

    .line 825
    invoke-virtual {p0, v1}, Landroid/widget/AbsListView;->setFocusableInTouchMode(Z)V

    .line 826
    invoke-virtual {p0, v2}, Landroid/widget/AbsListView;->setWillNotDraw(Z)V

    .line 827
    invoke-virtual {p0, v2}, Landroid/widget/AbsListView;->setAlwaysDrawnWithCacheEnabled(Z)V

    .line 828
    invoke-virtual {p0, v1}, Landroid/widget/AbsListView;->setScrollingCacheEnabled(Z)V
4) Change v1 to v2 in line828 like this:

Code:
.method private initAbsListView()V
Code:
.method private initAbsListView()V
    .locals 3

    .prologue
    const/4 v2, 0x0

    const/4 v1, 0x1

    .line 824
    invoke-virtual {p0, v1}, Landroid/widget/AbsListView;->setClickable(Z)V

    .line 825
    invoke-virtual {p0, v1}, Landroid/widget/AbsListView;->setFocusableInTouchMode(Z)V

    .line 826
    invoke-virtual {p0, v2}, Landroid/widget/AbsListView;->setWillNotDraw(Z)V

    .line 827
    invoke-virtual {p0, v2}, Landroid/widget/AbsListView;->setAlwaysDrawnWithCacheEnabled(Z)V

    .line 828
    invoke-virtual {p0, v2}, Landroid/widget/AbsListView;->setScrollingCacheEnabled(Z)V
5) Search for

Code:
.method public setScrollingCacheEnabled(Z)V
Code:
.method public setScrollingCacheEnabled(Z)V
    .locals 1
    .parameter "enabled"
6) Change enabled to disabled

Code:
.method public setScrollingCacheEnabled(Z)V
    .locals 1
    .parameter "disabled"

Guys, this appears to work very well on my Nexus 5 running SlimKat 7.8. I had some trouble, but when I finally managed to edit the files and swap out the framework.jar file, scrolling is out of this world!!! No more slow facebook scrolling, or laggy gallery scrolling. It is so good, that I am wondering - are there any drawbacks??? If not, why aren't all ROMs doing this by default. It's just great!!!
p.s. to the OP - Don't reference lines in the code!!! Lines in my file were different (for example your line828 to edit, on my framework was line850). Watch out for this guys! Just look at what you change, don't look at the line number! (e.g. not line828, but rather look for "setScrollingCacheEnabled(Z)V")

Lines are referenced because the thread is named "stock".

You might feel its a little worse if you scroll one line at a time but flings should be smoother. Personally I feel no difference.
