@regisca: Yes, I saw your solution, however it is only valid for the old version. Try again with the newly updated (the old one had the bug that it would accept 150 different instead of only one serial).

But you are very close :)
[Android Apps and Games] ssojyeti2:
Every time you click verify, the serial changes.
[Android Apps and Games] forceu:
Actually it should only change after you enter a new Username.

Do you close the app between?

Cracked the new hard one :)
[Android Apps and Games] maepchik:
good idea! ill try sometimes:)
[Android Apps and Games] LordManhattan:
Why is the NSA outside my door? The only thing i did after the hard one was trying to hack NORAD - and i did it. Thanks OP!

Gotta run!
[Android Apps and Games] youpi01:
Very good idea!

But I can not even "Kids"

Help me please!

( I used dex2jar and jd-gui)
[Android Apps and Games] regisca:
OK, did the new hard one.
[Android Apps and Games] forceu:
And that is correct :)
[Android Apps and Games] ssojyeti2:
I just beat kids mode! I feel important!
[Android Apps and Games] iuss:
Could you (or someone else) post the APKs for all four levels? I don't have a data connection handy..
[Android Apps and Games] forceu:
Check PM ;-) I prefer market, so I have some statistics :)
[Android Apps and Games] PhxkinMassacre:
grr haha i swear i found the serial for the kids one but when i put it in says its still wrong

it tells me the serial and when i insert it it don't work haha im going insane
[Android Apps and Games] AndyC87:
where can i learn to use alogcat and the other programs to hack this app? I'm so very new at this, but I do want to learn!
[Android Apps and Games] CollinsJ:
Interesting :)
[Android Apps and Games] ugothakd:
For of all of you complaining about kids mode not working...

MATH

. That being said, this is awesome! Just got kid, going to the next level :)
[Android Apps and Games] mistake37:
Nice idea, wanna try but no market access in here. Please, someone send me the apks? Thanks :D
[Android Apps and Games] forceu:
Check pm ;-)
[Android Apps and Games] Pimmos:
Finished the hard one

Just got the serial of the hard version. Shall I pm it to you forceu?
[Android Apps and Games] bluemeda:
Blind in medium
[Android Apps and Games] forceu:
I saw your solution in Google Docs, I like that all of you went a different way so far to get a working serial :)

Can send me the username to the serial you sent me as well? So I can confirm that =)
[Android Apps and Games] mistake37:
lol, gotta learn java in order to understand the algorithm, trying to make it self keygenner ^^
[Android Apps and Games] Pimmos:
Just pm'ed the username to ya
[Android Apps and Games] haploc:
Fun game. Got through Kids and Easy, and will (try to) tackle Medium and Hard later on.

A nice way to get to know about decompilers and other debugging tools!

Thx for that!
[Android Apps and Games] steelbytes:
all 4 done :-)

your mentioning dex2jar + jd-gui was interesting but misleading and wasted a lot of my time as the output from them wasn't valid java.
[Android Apps and Games] Fenny:
Were I writing an "uncrackable" application the strings, urls, etc... in it would be encrypted, and only the correct serial would be the key to un-encrypt it. I think this would be ideal for an application that uses web services as is the case with your google docs url. That would preclude the "easy" method of just patching out the serial check.
[Android Apps and Games] forceu:
Yes, however you have to keep in mind, that there are more then one serials (otherwise every user had the same serial), so you can't encrypt it with the serial algorithm.

In addition it would be very easy to patch the if statement that checks the serial with

"if (true==true) {....", so you don't need a serial at all but get the link.

And everything together, this is not about getting the link, but making the app to call the link ;-)

Yes, I would agree with you, if that was a commercial app that gives out the link to people who have a serial, it would be pretty insecure. But in this case, it would be just cheating ;-)
[Android Apps and Games] gnufabio:
Cracked the hard version. Thanks for the nice game :)
[Android Apps and Games] bled82:
For the people having trouble getting the serial to accept in (Kids) mode the read out from alogcat will show some thing like " D/hack Me (20750): Use any username with the serial <<12345x10^3>> " in order to ent the serial number in the app correctly you must convert the number correctly see example.

12345 x 10^3 = 12345000 so the serial number is 12345000

;)
[Android Apps and Games] Fenny:
Well, actually if the username was used to modify the algorythm then it would be mathematically possible to encrypt the strings with an xor key of some sort. Your strings would then have a constant xor value, but the goal is to make the serial and username generate the value. :)

The magic of this method is that the actual xor key is never in the code, and your key validating algorythm need only be a regex, and a socket call.
[Android Apps and Games] chipwreck1:
And..done.

Just finished hard - very cool "trick" how it's done.

If I had looked for this earlier, it could have saved me several hours, but it was fun this way :)

thanks again!
[Android Apps and Games] iuss:
Exactly this. The devil is in the details.
[Android Apps and Games] mindstate:
cant wait to try this out when i get home :)

downloading now! have no idea about hacking but would love to find out. i know what adb and logcat is and all that jazz but not hacking. wish me luck!!
[Android Apps and Games] forceu:
I updated the medium app, as it had a little bug that didn't read out some values. Should be fixed now :)
[Android Apps and Games] :
Yeah!

Mission accomplished!

User & serial found for all app :D

Thank you for this brilliant idea !

I'm learning Java since 2 weeks now and that a perfect practice !

EDIT : Can't get the code running under Eclipse, I don't have enough knowledges in Android yet :(
[Android Apps and Games] o0rebelious0o:
Question

So i've done the kids and easy ones; medium is definitely a step up thought... Unfortunately i know C++ not java but reading the java after dex2jar and jd-gui is okay. However, to extract the serial, is the idea we code our own method, recompile and run back on the device? given that it's SIM serial related i'm assuming it would have to be back on the device..? If so, how do we go about recompiling back from .class files into a jar and then .apk to re-run? Sorry but this is my first ever experience playing with android programming stuff :)
[Android Apps and Games] Jimibar:
You can use Eclipse and the Android SDK to compile the .class back to .apk

I'm stuck on this because I can't get the .class extracted by jd-gui running under my eclipse dev env.

Regarding the medium, I was thinking about getting the app a little more verbose :D
[Android Apps and Games] forceu:
I thought you may like some insights ;-) It is actually quite surprising for me, that there are so many users from Italy :D
[Android Apps and Games] AlbertHu:
i do not know what it is, but i'd like to give it a shot;)
[Android Apps and Games] boringbryan:
I am having trouble getting this to run in eclipse. It is choking on the labelXX parts. Can somebody please help? I am working on the medium.

Also, what is the best way to get this to run in eclipse? I am using the jd-gui and saving it that way.
[Android Apps and Games] Drakuwa:
I've just finished hard version, and I must say, I had more trouble with the medium one :D
[Android Apps and Games] PMGRANDS:
To do this... What must I first Learn?
[Android Apps and Games] Drakuwa:
Nothing special, just the proper use of the tools that that mentioned. For the first one (kids), you only need to read the log that is generated, and the other three, you need to know how to extract the code from an apk file, for example dex2jar classes.dex, and then decompile with jad/jd-gui, or get the dalvik code with baksmali/smali...
[Android Apps and Games] D200P13:
any tips for easy? besides downloading the apk to the desktop...lol
[Android Apps and Games] forceu:
Google baksmali/apktool and dex2jar, it will enable you to decompile an apk, so you can see the sourcecode =)
[Android Apps and Games] cliksantosh:
sry

MOD EDIT: you was warned already. dont ask for hack/cracks!
[Android Apps and Games] Skyline111:
Thanks,have to try it.
[Android Apps and Games] Drakuwa:
btw, forceau, what should I do to get in the high score list? Or that was only for the first few users? I've already filled the form in google docs with my solution to hard, maybe two weeks ago... and yeah, great experience! I'm really glad that I've found your apps :D
[Android Apps and Games] forceu:
Aw, I always forget checking Google Docs :D

Yes, you're right, that is the correct way to get a serial. Congratulations!
[Android Apps and Games] y0no:
Hi !

Where can found the APKs please ? I haven't access to the market. I will be happy if anyone can send these by PM :p
[Android Apps and Games] boringbryan:
I never got any help on this and was hoping somebody could answer me. I really like this app, I am just stuck.

[Android Apps and Games] orivier:
All are solved!

Great fun! I really enjoyed these riddles.

One comment towards the 'Evil Version' - the one you are working on :) (I hope) which I also wrote to you in the Google-Doc:

Medium and Hard require the same hacking technique. It would be nice to have a riddle that requires a different technique.

Thank you again for this great fun!

You can use ASTRO to backup your app, then you will find the apk file in the backups folder, where you can either pull it out or send it to dropbox.

Hehe, this is fun.. Took me 5 minutes to solve kids and easy. Medium took another 10.. Need to go to work now, but tomorrow i'll give the hard one a shot.. :)

As for kids: You don't even need to know any maths.. just do it like the code does.. append 000 to your "magic number" from logcat. ;)

As for easy: :eek: open your eyes

As for medium: toast it, baby.. toast it ;)

@OP: Great idea!

edit: do i see this correct?? 1500+ Download for the hard one and 14 solved it? :D

It would really be cool to see an app like this on WP7. But it would be even cooler to see one where the owner could send a signal to their stolen phone that would cause it to report to the local cop'ers and take and store and upload many pictures and all the while screaming, "This phone has been stolen" while overriding any and all volume controls.

[General Questions and Answers] Nebucatnetzer:
What is that with your providers? Isn't it possible to buy free phones in America?
[General Questions and Answers] pukemon:
Nothing is ever free. Free always costs something. Whether it back door, contract, advertisements, gotchas, less features than the paid version. Free has a cost.

I voided my warranty and your nexus.
[General Questions and Answers] Nebucatnetzer:
I mean phones without a contract. I pay for my phone 690$ without a contract that's the only "problem" but I sold my SGS II so it isn't that much money and I'm sure will stay longer with than with the SGS II. I prefer to pay the full price of the phone then have a locked version.
[General Questions and Answers] pukemon:
Well that changes everything free and unlocked are very different. Id much rather have unlocked too. But id much rather have unlocked and no carrier crap and stock android. With a sd card. Muahahaha.

I voided my warranty and your nexus.
[General Questions and Answers] lowandbehold:
I think you are misinterpreting what we are calling "stock android". Overseas phones, although free of carrier bloatware are not stock android. Samsungs will still have their touchwiz UI and HTCs will still have sense. The "stock" android we are referring to is free of the manufacturer overlays.

Honestly the first time you boot up your phone or restore it, it should ask you if you want HTC Sense, blur, etc or if you want Vanilla Android

[HTC EVO 3D] kaphtc:
I did quite a few searches about ROM's, Launchers, and other stuff. I have come to conclusion that I'll give CM7 a try. But currently I only know a few stuff, like, the CM7 will replace my stock ROM and I can choose AOSP to replace HTC Sense etc but I'm not sure if my GO Launcher will cross over to CM7. What about my apps? What about the apps placements on my home screens, would they be all reset or gone or what? I see a settings in GO Launcher that says it'll back up my GO Launcher configurations, would this restore my placements of apps on home screens? Also, I'm assuming the GO Launcher as the Desktop Dock apps for Windows and the CM7 as the OS of the computer. Am I assuming things right?

What's not working for HTC EVO 3D on CM7? I saw a video on youtube saying that the 3D video capturing doesn't work on CM7.

Regards
[HTC EVO 3D] oohaylima:
You're absolutely right. 4G and 3Ddo not work. But as development progresses, we're bound to be surprised.

Some widgets are ''Sense'' based so you might not see them cross over since cm removes sense. Apps should work.

I say dive in brother! Make sure to nandroid so that you can easily restore if you find its not your cup of tea. :D
[HTC EVO 3D] joeykrim:
Essentially, when moving from any type of Sense based ROM to an type of AOSP based ROM, you will probably lose all your settings, including Wifi passwords, brightness preferences, google accounts sync'd to the device, etc.

On the spectrum of ROMs available, view Sense on one end and AOSP on the other. Some ROMs try to sit in the middle and have features of both, but they always have to pick either Sense or AOSP as the base.

Sometimes you can move between different sense based ROMs and keep your settings/3rd party applications and sometimes you can't. Same goes for AOSP based ROMs.

If you've ever used a google device, G1, Nexus One, or Nexus S, they run pure AOSP by default. CM7 will be fairly similar to that type of experience plus some CM7 "tweaks/goodies".

Making a nandroid, as suggested above, is probably the best way to backup everything currently on the device, in case you want to revert. It will also help provide confidence when testing out new ROMs knowing you'll be able to revert to a previous one if something goes wrong.

To save you some time and help provide information on the next step, once you've selected a ROM and kernel how to make sure they are loaded properly.

If you're using the HTC unlock method on your device, there are basically two ways to load the kernel:

Oh! So I have to choose a ROM (I chose, CM7), Sense or AOSP and ALSO a kernel? My main purpose of flashing a custom ROM is to improve my battery life, get more customization options and cooler effects, no lags.

My status right now is I have S-OFF with Revolutionary tool and only GO Launcher installed. Where do I go now? Install Sense or AOSP (which one do you recommend), I understand E3D comes with HTC Sense 3.0 if that's the same sense we're talking about in above posts. Then install CM7? Which one goes first?

One more thing, if you don't mind. In the tutorial, it says it's for CDMA. Mine is GSM. Is there a difference between the two? If you say, yes, I'll look for another tutorial.

Yea, that is a problem. As far as I've seen, there is no CM7 release for the GSM version.
