Welcome back, guys.
It's time for the next page.
The orange bed.
And this challenge is a lot of fun because now we are getting back into our space paying application.
So we will apply our patch into a real world application into a real world game right now.
We have learned already that much.
Then we can apply this even if you are not feeling comfortable to do this right now.
So therefore let me give you some hints.
So at the moment we are having five lives and for a player like me, these are way too few to play this
game to reach a level which is comfortable for me right now.
Therefore, I would like to increase them, and my hints for you are the following.
Simply just use the APK tool to decode this application.
Then use your reverse engineering approach to identify the variable.
This instance field where these lives are being used, generated, created something like this.
There might be many values out there and you can try different approaches.
You can patch them one by one, or you can patch all of them at once.
Both approach should work.
Do not go too high.
Simply just use an end value.
For example, instead of the value five, which is the default value.
Use a value like six or seven because you may encounter some problems in there afterwards and save this
file.
Use the APK tool to build this application back again a simple line and sign it and then try it out
if it works.
The last thing I would like to give you on your way right now is the value of five, and this is the
value, the default value for our player lives.
So maybe it might be useful to search for values like this if you have identified the smiley file which
is containing our variable.
But think about this the value of five might not get stored as in decimal value.
It might be hex, who knows?
And therefore you might have to look for some additional characters in front of this five.
Alrighty.
Perfect.
Okay, so now let's go.
Let's do this challenge.
And don't be too afraid if you cannot solve this.
Absolutely no problem.
If we go through this afterwards, step by step and I will provide you additional hints on Yeah.
On points that might be challenging right now.
So therefore at least try to solve this challenge.
And afterwards we will go through this step by step.
Alrighty, perfect.
And therefore I would suggest let's go.
Let's start increasing those player lives to a little bit higher number.
Let's say six or seven.
Don't go too far right now.
Just increase them a little bit and afterwards you can try going too far.
All righty.
Let's go.
