What is this? Let me explain you. It will Bypass the signature checking of sony. Sometimes when we mod any system app and put it back in to system with correct permission but the app doesn't work or doesn't install or force closes. Or Some of the apps from other sony device like Z1, Z Ultra, Z etc. are not installing in our phone even we put them in system with correct permission but they don't work. Most of the time these problems are happening because of signature checking.

Here I will teach you How To Mod Your services.jar To Bypass Signature Checkin

Make sure you have a basic knowledge on how to compile/decompile .apk/.jar files.

  • Decompile services.jar

    [*]Navigate to \com\android\server\pm

    [*]Open PackageManagerService.smali file in file editor

    [*]Search for .method static compareSignatures

    [*]Original code looks like this (it can be different in different build of firmware)

    Code: 
    .method static compareSignatures([Landroid/content/pm/Signature;[Landroid/content/pm/Signature;)I
    .locals 7
    .parameter "s1"
    .parameter "s2"

    .prologue
    .line 2612
    if-nez p0, :cond_1

    .line 2613
    if-nez p1, :cond_0

    const/4 v6, 0x1

    .line 2632
    :goto_0
    return v6

    .line 2613
    :cond_0
    const/4 v6, -0x1

    goto :goto_0

    .line 2617
    :cond_1
    if-nez p1, :cond_2

    .line 2618
    const/4 v6, -0x2

    goto :goto_0

    .line 2620
    :cond_2
    new-instance v3, Ljava/util/HashSet;

    invoke-direct {v3}, Ljava/util/HashSet;-><init>()V

    .line 2621
    .local v3, set1:Ljava/util/HashSet;,"Ljava/util/HashSet<Landroid/content/pm/Signature;>;"
    move-object v0, p0

    .local v0, arr$:[Landroid/content/pm/Signature;
    array-length v2, v0

    .local v2, len$:I
    const/4 v1, 0x0

    .local v1, i$:I
    :goto_1
    if-ge v1, v2, :cond_3

    aget-object v5, v0, v1

    .line 2622
    .local v5, sig:Landroid/content/pm/Signature;
    invoke-virtual {v3, v5}, Ljava/util/HashSet;->add(Ljava/lang/Object;)Z

    .line 2621
    add-int/lit8 v1, v1, 0x1

    goto :goto_1

    .line 2624
    .end local v5           #sig:Landroid/content/pm/Signature;
    :cond_3
    new-instance v4, Ljava/util/HashSet;

    invoke-direct {v4}, Ljava/util/HashSet;-><init>()V

    .line 2625
    .local v4, set2:Ljava/util/HashSet;,"Ljava/util/HashSet<Landroid/content/pm/Signature;>;"
    move-object v0, p1

    array-length v2, v0

    const/4 v1, 0x0

    :goto_2
    if-ge v1, v2, :cond_4

    aget-object v5, v0, v1

    .line 2626
    .restart local v5       #sig:Landroid/content/pm/Signature;
    invoke-virtual {v4, v5}, Ljava/util/HashSet;->add(Ljava/lang/Object;)Z

    .line 2625
    add-int/lit8 v1, v1, 0x1

    goto :goto_2

    .line 2629
    .end local v5           #sig:Landroid/content/pm/Signature;
    :cond_4
    invoke-virtual {v3, v4}, Ljava/util/HashSet;->equals(Ljava/lang/Object;)Z

    move-result v6

    if-eqz v6, :cond_5

    .line 2630
    const/4 v6, 0x0

    goto :goto_0

    .line 2632
    :cond_5
    const/4 v6, -0x3

    goto :goto_0
.end method

    [*]Replace the whole code with this

    Code: 
    .method static compareSignatures([Landroid/content/pm/Signature;[Landroid/content/pm/Signature;)I
    .registers 9

    const/4 v0, 0x0

    return v0
.end method

    [*]Save the file

    [*]Recompile your services.jar

Naming it as superuser mod might be more well known
