Make sure to read the mod notes and carefully follow the instructions. Also, make sure you uninstall any other
Lucky Patcher apps first, if any.
For those who can't get this to work for whatever reason, please download this file:
Download file - MonetizationVars
sbupload.com
and move it to sdcard/Android/data/com.candywriter.bitlife/files/
Overwrite any existing files eventually. If the downloaded file comes with the ".bin" extension, make sure to remove it. The file name should be only "MonetizationVars" without any file extensions, and a file with the exactly same name should already exist in your data folder, if you already played this game at least once before.
Then, launch the game and all IAPs will be unlocked.
