apps_compressed.bin

With PSAS (only FULLversion) it is possible to "decompress" apps_compressed.bin for investigation.
It uses Algo:
TkToolVer:1.6.3
I don't know way to make own apps_compressed.bin.
As Multiloader for instance not accept decrypted apps_compressed.bin
As example some older apps_compressed.bin from S8500.

u reache some limit bro........... cant download from RS........but good going

can u write a tutorial
so that other members too can find something
thanx!
gr8 gng mate

PSAS can only decrypt in Full Version.
Costs 30 Euro...
BUT I can upload via Request some decrypted files for study.
I'm not an Seller of PSAS nor I force you to buy PSAS.
But this is the only Tool I know, which decrypt these apps_compressed.bin and bootloader.mbn. Tested by me with:
S5250
S5330
S5750
S7230
S8500
S8530
http://forum.revskills.de/viewtopic.php?f=14&t=700
Wait few minutes. I will upload to megaupload... from S8500 as example.
Best Regards
Edit:
Download example apps_compressed.bin taken from S8500:
http://www.megaupload.com/?d=2JIKS8QD
Same as in first post.

So what did u get inside that?? What was compressed in layman terms pls.......

Expect not too much. Depend on knowledge...
Now file is "human readable"... Ready for Reverse engineering.
Minimum Requirement HEX Editor...
Then you can find Text like this:
Please receive DB2 by TkFileExplorer.exe !!primaryRecord
Click to expand...
Click to collapse
Remember where u saw TkFileExplorer.exe else...
You could search for Textstrings... like:
widget
bondi

So many things to explore.

hi guys I'm working on some bada's modding projects...
is it possible to have an example of uncompressed files?
thank you in advance
edit : I have now seen the uploaded uncompressed file...
I hoped it was more "human" readable...

Hi,
could you upload the decrypted bootloader, too? Maybe someone here will find some exploitable code in that will help "jailbrake"-ing the system, or allow booting unencrypted OS (modified Bada or Android from Galaxy S for exmaple...)
TIA!

Hi adfree,
Can you say me the name of PSAS software please?

http://psas.revskills.de/
RevSkills is the new name of PSAS.
This feature only in registered Fullversion possible.
NOT in Trial Version.
Best Regards

Thanks but seems to be not compatible with windows 7 64 bits
Will try later, Have a good night adfree

look like that apps_compressed.bin contains a big secret
i flashed amss.bin file & apps_compressed.bin file from spoofable fw as an update for non spoofable fw and the result was getting a spoofable fw with its code name in the about phone menu but i lost all the updates made in the non spoofable fw
can anyone know where is the part in the app_compessed.bin that allow spoofed games run or not?????

To clarify:
I'm NOT support spoofing.
Prior files were not decompressed, "only" decrypted.
But now.
http://rapidshare.com/files/453882158/XXJL2decrypted_apps_decompressed.rar
File is from XXJL2.
Maybe we can find other usefull infos.
Best Regards

Now we can encrypt.
Thanx to ho1od
Any suggestions?
Mabye few things can be enabled or disabled...
TRUE can be found 600 x
FALSE over 700 x
Best Regards

I'm working on decompression QMD, thanks to mijoma

I was looking for the decompressed files of apps_compressed.bin (S8500XXJL2 and S8500XEKC1 only), but the link does not work.
If anyone (or you, adree) can decompress (not only decrypt) those files and upload them somewhere, that would be very kind/nice. Maybe I can work something out and if we are ever able to encrypt the files back, we may have a new better cleaned up version by that time.
Btw, thanks for the efforts, adree and ho1od.

I already tryed to increase the max. resolution to 8000x8000px for jpg a week ago but it didnt worked
This file exists 2 times and I flashed them correctly to the wave (tested with sTunes after flash), the limits seems to be set somewhere else...
The image sizelimit is also higher than 4096000 byte (or what it is) - about 10 mb.

I would have liked to tweak this setting to 200 or more and see but unfortunately there are not that many good apps to install.
<MaxInstallCount>
<NativeApp value="300"/>
<NativeWidget value="50"/>
<JavaApp value="-1"/>

Btw, what does this Java value mean ? Could it be that it controls whether to show icon in Menu or not ?

@ st0rmi
Thanks.
Yes, via sTune this file is twice.
It seems writeprotected files are most in folder SystemFS... as Backup.
If you check via TriX Firmware files. Then Contents.xml is in *.FFS... maybe edit before flashing. Then changes in both files on handset.
Not tested yet...
@ rex4u
At the moment I have nothing changed in this file, so no idea what happens.
Maybe soon few tests...
Best Regards

@adfree: Yeah thats what I have done
I just used sTunes to copy the contents.xml back to my pc and view if the edited xlm are really on my phone because it didnt worked...

@adfree
No bro' I was offering my own suggestions to this configuration file.
It might allow us to install more than 100 apps in phone and show in Menu.
Second it might show Java apps icons in Menu.
My 2 cents

xml parser
please help me
a want to parser punker xml data base.

it's into the 'app counter' field, '-1' may be means 'unlimited' number of java apps installable, but I haven't read yet the whole xml... anyway if it is editable it's an interesting thing..

I saw that file a while ago while looking for something inside my phone (very special thing that made me to copy the whole phone)
there is a lot of interesting things but i never tried tweaking it
Maybe if someone have enough knowledge to add few new extensions and test them
Also removing some stupid limits would be awsome
Sorry i've no time to test that with you guys but would appreciate results
Best Regards

You dont need modif ffs or other just use pfs file to modif what you want and in real time direct phone flash pfs file and not have write protect problem
Just says Thank
Example file : dont give attention of boot img cause i dont take time to do it in 800x480 but its 400x240 then its make bug but with pfs file you can upload anything you want to change !!!
Good hack !!!
Maybe with this you can create dual boot or i dont know what a pro smoker can do, you can also try to put her rc2 or rc1 directory i dont try it !!!
Download example, in this one you can see SystemFS and Registry directory, off course you can put her all directory you want to flash pfs, using trix to modified or wave remaker more faster :
https://rapidshare.com/files/809973956/Circle.pfs
An idea its like you can make your one firmware with personal Widget installed and other idea welcome....Just take file registry and Widget folder on phone and put it on PFS

QuB an mighty Tool for Samsung handsets

This Tool is amazing. Many features.
Source is here:
http://rk-team.net/showthread.php?11-%CD%EE%E2%FB%E5-%E2%E5%F0%F1%E8%E8-QuB
"Lesson 1"
Make hidden folders visible for research and Backup.
For instance folder System is the RC1 file, mounted into RAM...
Many Thanx RusEm and Team.
Best Regards

Hi thank you for this tool but it is only for "qualcomm" platforms i think (not sure). In s8500 qualcomm is only processor for calls.

QuB is designed for Samsung handsets.
This command is 100 % working on S8500 and U700, tested by me.
You have to select same COM Port like you would choose for File Manager...
No magic.
Then you have access to nvm folder, system folder and few more...
System folder is read only as it is the mounted RC1 file...
Best Regards

But... with this... what kind of researches could be done?

If you can decrypt bootloader... that's mean you're closer to install other os?
Ok, maybe the information given in "lessons" can cause more expectation
Waiting for lesson three!

does all these features run on trial mode???
or should i buy the app
there is no profile for s8500 why???
i know you are not the developer of the app adfree but i just wanted to put those questions

does all these features run on trial mode???

@adfree: take a look at the screen, i got only question mark on the application. do you know what is the problem?? may be due to lang files ??

Main Language is Russian.
See Screenshot. Blue marked... then you see right Russian-> change into English.

wonderful new tool
-i am able now to view the files in the ram but don't know what to do with them
-after decryption of apps_compressed.bin i found out that i have a very little brain to modify in that file
i can't wait for lesson 3
thanks adfree and good luck

I was not able to decompress with QuB, maybe my fault...
Helpfull would be, to know which part is with CheckSum.

Really nice tool.
Setting FmSecureMode to off gives us the chance to see where everything is located and we can investigate and chang the files on the pc. now we need to find a way to get them back to the wave
Maybe with PfsDeleteList.txt / *.pfs ?
Also after reboot FmSecureMode is set to on again.
But we can already see where the fonts are located, that the sms viewer is html/css based like the one for email and any other messages (so we can easiely change layout, colors, font-size,...) and a lot of other things like replacing images etc.
When we get this working, nothing keeps us anymore from a fully customized bada

In combination of TkFileExplorer 2.4 you can see this.
Caution!
Renaming or other Directory Manipulation can lead to Bootcycle.
At your own risk.

Need help in decompressing Rc1 and Rc2 files. I see some tabs in Qub saying Rc1 and Rc2. Dont know how to use them to dump rc1 and rc2 files. And if I do, is there any way to upload them back like in trix. Or can you use trix to decompress rc1 and rc2 files? If yes, how? Help would be very much appreciated.

How can we edit *.so file?

I found into shp folder *.so files and I want to ask if we can edit them
because I want to see what have in the files
OpEuroIME.so and OpEuroIMESetting.so

HEX Editor... expect not tooo much.
This leads to this...
http://forum.xda-developers.com/showthread.php?t=1294406
But we could investigate, if this or other files about language is in arabic S8600...
Best Regards

.so are equivalents to .dll libraries which you can find in Windows. They contain almost only machine code.
And you cannot edit them, because these are digitally signed, first you'd have to bypass integrity&sign check mechanisms.

Some one using Linux can try this program please?
http://www.fileinfo.com/extension/so
Not to edit, but if it was possible at least to read .so file?

you can see GCC compiler in SDK files....of course if you have it
"SDK Path"\Bada\2.X.X\Tools\Toolchains\ARM\arm-bada-eabi\bin\gcc.exe
You can see this in the readme file too
The executables in this directory are for internal use by the compiler
and may not operate correctly when used directly. This directory
should not be placed on your PATH. Instead, you should use the
executables in ../../bin/ and place that directory on your PATH.
Click to expand...
Click to collapse
So any ideas about a DEcompiler
This is just a compiler that make .so files....Maybe non-compressed ones only too
Best Regards

ML90 Did you try to see so file with SDK?
Because I never used it

There is nothing to see in there
You can use gce2elf plug-in for trix to decompress .so files from bada 2.0 and the files will be converted to elf files that were available in bada 1.2 FWs before
S8600 .so files can't be decompressed until now !
There is no way to compress files back yet !
As i say these files can contain pure code and no pics or any stuff like that as they are compiled from .O libraries files used by C/C++ apps
We need the real experts to come back and help us
Best Regards

Thanks for your answer.
Even if we got pure c++ code perhaps we should be able to see what for exemple setting.so file call on other file firmware... that was my idea
After I know we can not rebuild a file, but it's just to have some more infos that should be usefull?

After I know we can not rebuild a file...
Click to expand...
Click to collapse
This is not 100 % correct...
*.so files are signed... So Security is main problem...
To modify or to rebuild is only problem of skills...
If "Android boys"... ...
See here:
*.so files are also known in Android world...
http://forum.xda-developers.com/showpost.php?p=23559274&postcount=15
Android use folder lib with *so files...
Maybe good chance to find some source... if these files also open source...
But again.
Break first Security check, then you can modify *.so files... depend on your brain.
But at the moment Dead ends...
Smart skilled users on ""holiday""... or missing in action...
First "safe" attempt to remove Security Check:
apps_compressed.bin...
Compression Algo needed... as you have no full access in compressed BINary...
If Bootloader checks *.so files... maybe FOTA could help...
To break RSA 2048...
I hope few of our smart Devs come back to bada Hacking.
To search and find *.so sources in Android world is not useless...
Maybe it helps to better understand.
Best Regards

hi,
editing is not a problem - we dont need to compress gce back - similar situation to rc1/qmd image (gce is light weight qmd version)

Happy to see you there Kubica, we realy need your knowledge
Bada have no big interest if we can't custom firmware (thanks to samsung ).
Someone could post and edited so file please? it's just to see relation with others files in the firmware.

You have just discovered a method to install applications like .apk for Android?
If yes.... :') i would be so happy!! (we would be!)
A new era could begin.
great work AdFree! as always

I heard that first version of bada (1.0) was able to install *.oap files, but samsung disabled it to prevent from installing piracy apps. Maybe some CSC feature or variable in firmware?

So cool
but I tested both encoded OAP and decoded OAP and none of them works!!!
but a problem is that when i open asphalt6.oap with size of around 400mb it shows error without even 1 second loading
so where is the problem?!!

Well
You need to see this
It is so funny
This is DCF file
Of course it throw on me an error after opening dolfin

Tested short on JL2 ...
oap is not supported file... but DCF same info.
On bada 2.0 DCF leads to wrong site... maybe because this:

From may 2010...
But remember... We have to differ between bada SDK (Developer) signed "testapps"... commercial apps from store... and Samsung signed apps...
But please take an look into:
AppEx\Sys\SamsungApps\SamsungApps.oap
Their are 3 more oap (ZIP) which are autorestore if you delete the apps from Osp folder...
Also all transfered files from Kies or from internal Store are oap (ZIP)...
Maybe we have to find correct folder...
Maybe we need license file + oap...
Maybe...
But why Samsung integrate this into handset visible for us?
Samsung has humor like this Andromeda Warp thingie...
An kind of easteregg?

I can install Samples like in SDK...
"Cert B" = rootCACert.cer
I can install Apps from store...
"Cert C"
All 3 Installations from SD Card or internal Memory with simple zipped files.

Stotter spotz.. since when does Bada support zip files

So how did you installed apps?
is there a special location we should put special certs there?

OAP Installation only successfully in XPKG5...
In other Firmware blocked...
Not sure yet why...
I will do some more tests...
XPKG5 include ZIP + OAP files... they are not 1 : 1
BDAgent.oap
BDAgent.zip
Maybe OAP need special Flag to work... will try if I am back on other Firmware...

hi adfree, I long to write to you on this issue with the files.

Maybe winmerge is useful for comparing differences of these 2 files
BTW can device handle encoded OAP files?

@ maniek909
Your file is ENcrypted *.oap... During Installation on Wave it will be DEcrypt into "other Format"...
Then second *.oap file is only ZIP Archiv...
@ r_22009
Total Commander can compare 2 file also.

Now i have XPKG5
would you mind telling a short tut to install OAP?
thanks

would you mind telling a short tut to install OAP?
Click to expand...
Click to collapse
Only XPKG5...
1.
Install Certs... start with Cert from bada SDK:
rootCACert.cer
2.
Your app is now in ZIP Format... Check it or create self.
Rename into .oap
Remember, with rootCACert.cer you have to try better with bada SDK signed Apps...
Other 2 Certs came from Firmware... extract them...
Code:
Samsung_RootCA.crt
SamsungSBRootCA.cer
Best Regards

would you mind uploading the first cert as i dont have SDK? thankx

I am little bit paranoid...
I don't think Samsung is my best friend, if I share now their Certs...
To protect myself...
Btw...
Please be sure... you have visit and read some other threads...
As rootCACert.cer is floating around...
Btw 2...
I have forgotten, that Samsung moved in bada 2 to RSA 2048... before most RSA 1024 used in bada 1.x ...
So more Certs possible to try...
@ r_22009
Summary for you...
Use search or Google ...
Input:
rootCACert.cer

S8530 XPKD6 can also handle OAP...
Maybe interesting for research...
