for anyone that just can't seem to get it to read the obb file here's what I did. try the standard way download the apk and then obb, extract the obb to >com.ftt.boxingstar.gl.aos<, so it's Internal storage> Android> OBB >com.ftt.boxingstar.gl.aos. If that doesn't work then just do the same thing but instead of Android go to downloads ( I re-download the files without getting rid of the extracted one you can choose not to not sure if it would change anything tho) there should be a folder in there with the name of the download file or if you chose to change the name, for me it was BOXING_STARS_OBB, from here it's straight forward just keep going through the folders by clicking and copy the extracted file in that obb folder. don't forget your vip License ( and make sure that your license doesn't end in .TXT because then it won't work if your phone allows it then edit the name and delete the .txt from it and your good) you should be fine now.
