Programm for JL bluetooth chip

I have some China made promotional speakers in stock. These speakers were custom made to us by programming bluetooth chip to have a special name (pairing name) and sound (instead of the regular turn on, turn off, paired, etc sounds, speaker plays our "own" sounds with each function).

I need to change those customized sounds and names to a more "generic" mode and I've heard that it can be done through a program that could be inserted in a CF card and that executes when speaker is turned off with the card inside.

The goal is to replace the current settings (name and sounds) by new ones in a very simple way as we don't have electronic capabilities to change chips physically.

BT chips brand is JL from a company in China.

Please refer to the attached internal pictures of the speaker and chip.
