Alright men/ladies welcome back to another tutorial ib this tutorial you'll learn how to modify Developer Assistant that's used to modify apps on your devices.. You'll be learning how to make it "Permanent Commercial Licence"..
So I'll be using just MT Manager So extract 'Developer Assistant' now goto & View & open classes.dex head over to search "Permanent"

search results (2) - "permanent"

Code:
com.jw.devassist.domain.license

[I]C[/I]
[COLOR="#00FFFF"]const-string v4, "Permanent"[/COLOR]

[I]Validity[/I]
const-string v2, "Permanent"

Code:
 method static constructor <clinit>()V
    .registers 10

    .line 1
    new-instance v0, Lcom/jw/devassist/domain/license/c;

    sget-object v1, Lcom/jw/devassist/domain/license/b;->d:Lcom/jw/devassist/domain/license/b;

    sget-object v2, Lcom/jw/devassist/domain/license/Validity;->Permanent:Lcom/jw/devassist/domain/license/Validity;

    const/4 v3, 0x0

    const-string v4, "Permanent"

    invoke-direct {v0, v4, v3, v1, v2}, Lcom/jw/devassist/domain/license/c;-><init>(Ljava/lang/String;ILcom/jw/devassist/domain/license/b;Lcom/jw/devassist/domain/license/Validity;)V

    sput-object v0, Lcom/jw/devassist/domain/license/c;-[COLOR="#00FFFF"]>f:[/COLOR]Lcom/jw/devassist/domain/license/c

Goto the navigation icon & copy field signature then find usage
Navigation.jpg


This should be what you copied
Code:
Lcom/jw/devassist/domain/license/c;->f:Lcom/jw/devassist/domain/license/c;

goto.jpg


Code:
 sget-object v0, Lcom/jw/devassist/domain/license/c;->f:Lcom/jw/devassist/domain/license/c;

    const/4 v1, 0x0

    invoke-direct {p0, v0, v2, v2, v1}, Lcom/jw/devassist/domain/license/l;[COLOR="#00FFFF"]-><init>[/color]

Now Replace .Line 2 & .Line 7 & paste in the field signature

Code:
.method public constructor <init>(Lcom/jw/devassist/domain/license/c;)V
    .registers 2

    .line 1
    invoke-direct {p0}, Ljava/lang/Object;-><init>()V

    .line 2
    iput-object p1, p0, Lcom/jw/devassist/domain/license/l;->a:Lcom/jw/devassist/domain/license/c;

    const/4 p1, 0x0

    .line 3
    iput-object p1, p0, Lcom/jw/devassist/domain/license/l;->b:Ljava/util/Date;

    .line 4
    iput-object p1, p0, Lcom/jw/devassist/domain/license/l;->c:Ljava/lang/Integer;

    const/4 p1, 0x0

    .line 5
    iput-boolean p1, p0, Lcom/jw/devassist/domain/license/l;->d:Z

    return-void
.end method

.method public constructor <init>(Lcom/jw/devassist/domain/license/c;Ljava/util/Date;Ljava/lang/Integer;Z)V
    .registers 5

    .line 6
    invoke-direct {p0}, Ljava/lang/Object;-><init>()V

    .line 7
    iput-object p1, p0, Lcom/jw/devassist/domain/license/l;->a:Lcom/jw/devassist/domain/license/c;

    .line 8
    iput-object p2, p0, Lcom/jw/devassist/domain/license/l;->b:Ljava/util/Date;

    .line 9
    iput-object p3, p0, Lcom/jw/devassist/domain/license/l;->c:Ljava/lang/Integer;

    .line 10
    iput-boolean p4, p0, Lcom/jw/devassist/domain/license/l;->d:Z

    return-void
.end method

Code:
sget-object p1, Lcom/jw/devassist/domain/license/c;->f:Lcom/jw/devassist/domain/license/c;

Should Look Like This

Code:
.method public constructor <init>(Lcom/jw/devassist/domain/license/c;)V
    .registers 2

    .line 1
    invoke-direct {p0}, Ljava/lang/Object;-><init>()V

    [COLOR="#FF0000"]sget-object p1, Lcom/jw/devassist/domain/license/c;->f:Lcom/jw/devassist/domain/license/c;[/COLOR]
 
    iput-object p1, p0, Lcom/jw/devassist/domain/license/l;->a:Lcom/jw/devassist/domain/license/c;

    const/4 p1, 0x0

    .line 3
    iput-object p1, p0, Lcom/jw/devassist/domain/license/l;->b:Ljava/util/Date;

    .line 4
    iput-object p1, p0, Lcom/jw/devassist/domain/license/l;->c:Ljava/lang/Integer;

    const/4 p1, 0x0

    .line 5
    iput-boolean p1, p0, Lcom/jw/devassist/domain/license/l;->d:Z

    return-void
.end method

.method public constructor <init>(Lcom/jw/devassist/domain/license/c;Ljava/util/Date;Ljava/lang/Integer;Z)V
    .registers 5

    .line 6
    invoke-direct {p0}, Ljava/lang/Object;-><init>()V

    [COLOR="#FF0000"]sget-object p1, Lcom/jw/devassist/domain/license/c;->f:Lcom/jw/devassist/domain/license/c;[/COLOR]

    iput-object p1, p0, Lcom/jw/devassist/domain/license/l;->a:Lcom/jw/devassist/domain/license/c;

    .line 8
    iput-object p2, p0, Lcom/jw/devassist/domain/license/l;->b:Ljava/util/Date;

    .line 9
    iput-object p3, p0, Lcom/jw/devassist/domain/license/l;->c:Ljava/lang/Integer;

    .line 10
    iput-boolean p4, p0, Lcom/jw/devassist/domain/license/l;->d:Z

    return-void
.end method

Now just save & exit you're work like so
