Need Cube Mini Purple Bootloader

I am using an early version Cube Mini Purple, and I received it bricked. So I tried flashing a Cube Mini Purple bootloader and when I connect to Mission Planner I get an error saying “Config Error: Failed to update IO firmware”. I suspect I may have flashed the newer version bootloader for the newer Cube Mini Purple.

Is there anyone who has the bootloader for the early version of Cube Mini Purple?
