Tutorial Tutorial: How to create a custom patch for modded apps

[VolcanoMods]

Hi (platinmods) User
Today I'm gonna teach you how to create custom patch for modded apps for faster releases & less time consuming

First I learned this from Morthis so all credits to him

Things you're gonna need
1-Android SDK, Java & WinRar
2-Baksmali Download it
3-010 Editor Download it
4-Lucky Patcher Download it from here
5-Rooted Android phone


Note this will work only if the modds are minimal like changing const/4 v0, 0x0 to const/4 v0, 0x1
if you add const/4 v0, 0x1 to a code which was not existed originally this will not work also this may only work if you add the custom patch directly to the untouched app not by creating modified apk (I'm Not Sure why)

I will take Pic Collage as an example to create a custom patch to unlock its IAP using Lucky Patcher for future updates of the app
Download untouched apk

1-Baksmali Pic Collage using baksmali
2-Samli the app without changing anything in smali
3-Open "finish" folder and extract the classes.dex of Modded_Pic.Collage using WinRar
4-Move the classes.dex to any other location e.g. Desktop
5-Do the changes in smali to unlock

method public final a(Lcom/cardinalblue/android/piccollage/a/a/p;Lcom/cardinalblue/android/piccollage/a/a/r;)V

    .locals 4

    .parameter

    .parameter

    .prologue

    const/4 v1, 0x0  ==== change it to const/4 v1, 0x1

    .line 432

    const-string v0, "StickersActivity"

    new-instance v2, Ljava/lang/StringBuilder;

    const-string v3, "Purchase finished: "

1-Baksmali Pic Collage using baksmali
2-Samli the app without changing anything in smali
3-Open "finish" folder and extract the classes.dex of Modded_Pic.Collage using WinRar
4-Move the classes.dex to any other location e.g. Desktop
5-Do the changes in smali to unlock IAP

so the patch code will begin from 6C 00 00...
12 Create new text document, name it to app package name in this case is com.cardinalblue.piccollage.google
13-After copying the changes obtained from 010 Editor to the text file move it to lucky Patcher folder
Text document should be like this

[BEGIN]
Pic Collage IAP Patch
For 3.6.15+

[PACKAGE]

[CLASSES]
{"original":"6C 00 00 00 12 01"}
{"replaced":"6C 00 00 00 12 11"}

[END]
