here is ur crack and is internal release dont share plz

and those 70 files are media files magic no. rÞˆdG¨¨ seems religious files anyway they decoded only when user click play n u can play them in the app ,i guess 8 files makes 1 media files they get appended and decoded

demo limitation of 1min removed
proper unlocked on all devices no 3 device limitations

Download :- http://www48.zippyshare.com/v/NBIO8Brr/file.html

@jasi2169
Jasi, for internal releases you should use the attach button when posting ;)

niculaita 10-20-2015 05:36

I have too cracked long time ago old version but gives error after a while,
code is more clear there.

I have found old original kit and post here too cause it works on older devices too.

http://www22.zippyshare.com/v/IeDujyzM/file.html

please fix this too cause mine solution crashes after some minutes !

I tell this cause new version untouched 1.8 demo gives me break of sound when try to use buttons more times.
I will try now with cracked version on second phone to see if programs is more compatible or not.
so I am still using old version.
crypted files in old version can be founded decrypted during playing on card

I am very happy that doxa Team URET exists !!!

Jasi2169 10-20-2015 15:44

please check your PM inbox because there is a link of an other soft named isokratis PE v4.1.3 or here is a new link http://tempsend.com/E1E9B75B80

https://play.google.com/store/apps/details?id=gr.psaltiki.isokratispa

P.S. 1. because original does not work well regarding buttons on my particlar phone,
it is not your fault
Indeed on other phone original and your crack work both well.
I do tested myself demo and crack works well.

2. old isokratis_A v1.0 it is easier to be cracked, code is not obfustrated at all
and works on old and new devices well.
I have changed some ifs conditions then rebuild and resign apk.
I would like you as proffesional to take a look at them.

Anyway I am very pleased for what you have done.

niculaita 10-23-2015 22:21

Hi
is there nice debugger for java program ? like JEB or IDA

simx 06-14-2017 01:16

Hi all,

Sorry to grave dig but I am trying to get hold of JDebugTool.
Their site is down and rather than download it off some random site I thought I would ask you guys.

Thanks in advance.

Anyone have experience with protected java software with ZKM 5? Not only string deobfuscation but also the part of code encrypted/obfuscated.

Thanks

sendersu 10-24-2017 01:05

@inode
for string deobf there are tool(s), but for code obf.... thats a very good question!
I;m also interested in!

ideally there should be a tool like de4dot but for java needs :0 (dreaming)

reversing_solo 10-24-2017 14:12

String deobfuscation is really simple in ZKM, but it seems there is also others kind of obfuscation on the binary that I'm working for, it seems that all the code is obfuscated. Maybe some other ZKM advanced configuration.

There is some new deobuscator for the strings, I tried it but doesn't work in this case. Note that the version that I'm working on is ZKM 5 and not the new one.

I saw that there is a leak of ZKM 5.5.8 but I'm not able to find it on the internet, maybe someone can send me it if he got that copy?

public onClick and added move-object v0, v1 see at line 67 also compareTo and key near.png
Link:
https://www101.zippyshare.com/v/9wgyFTaQ/file.html

so, question is: how to make android program pop up the v0 value after line
move-object v0, v1
????

CodeCracker 02-08-2019 02:33

This is more like Android reversing...

Android boolean examples:
A boolean method changed to return false:
1200 const/4 v0 0
0F00 return v0

A boolean method changed to return true:
1210 const/4 v0 1
0F00 return v0

In your example niculaita:
move-result v1
; this set v1 with 1/0

ifnez v1, : cond1
; check v1

Java String compareTo() Method returns 0 if strings are equal!

As far as I know, there is no real jvm byte code debugger.

You can use to decompile java codes the RECAF too, https://www.coley.software/Recaf/
