LLSIFAS KLBVFS EXPERIMENTAL TOOLS

conjunto de herramientas experimentales para extraer y ordenar los datos sacados del juego, scripts experimentales para aprender como funciona el vfs del sifas, etc.

tools.py chu 101 mikan_models

tools.py test

TODO

  • extraccion y ordenamiento de stages
  • comando para extraer stages filtrado por generacion/subunidad
  • (funcion decrypt) comprobar que el archivo existente no sea un placeholder de 0kb y reescribir en tal caso
  • copiar los packs acb/awb de m_asset_sound junto con los stages ordenados
  • actualizar automáticamente los packs, masterdata.db y assets*.db con las nuevas claves sacadas del shared_prefs, directamente del dump.

CHEATSHEET DE COMANDOS (NO ES UN PROCEDIMIENTO)

  • adb pull /sdcard/Android/data/com.klab.lovelive.allstars.global com.klab.lovelive.allstars.global
  • adb backup -shared com.klab.lovelive.allstars.global -f sifas_data.ab
  • java -jar abe.jar sifas_data.ab sifas_data.tar
  • ./klbvfs.py decrypt .db_.db
  • ./klbvfs.py dump --types=member_model

INFORMACION ORIGINAL DE KLBVFS

This is a proof-of-concept implementation of klab's encrypted sqlite3 vfs (virtual file system). It can be used to query encrypted databases in your /data/data/com.klab.lovelive.allstars/files/files directory

It assumes your directory structure is the same as it would be on your android device to extract your master key from shared_prefs . so you must dump your /data/data directory as is, or run this directly on your phone.

To get all the files in the right directory, get all the pkg files and .db.* files in one folder, then copy the klbvfs.py file to that directory.

Usage

You need python3 and pip installed

If you have python venv:

python3 -m venv env
source env/bin/activate

Then install dependencies

python3 -m pip install -r requirements.txt

Now you can use it

./klbvfs.py query masterdata.db_* "select sql from sqlite_master;"
./klbvfs decrypt *.db_*.db
./klbvfs.py --help
./klbvfs.py dump [--types [[...]]] [directories [directories ...]]

Example (while in the directory with all the pkg folders):

./klbvfs.py dump --types=member_model

This also registers a python codec for klbvfs which can be used to decrypt like so

key = sqlite_key('encrypted.db')
src = codecs.open('encrypted.db', mode='rb', encoding='klbvfs', errors=key)
dst = open('decrypted.db', 'wb+')
shutil.copyfileobj(src, dst)

Future development

I'd like to actually make it dump all the pkg* files with correct names and directory structure. the mapping between virtual paths and pkg dirs is stored in these db's among other stuff
