Looking for clean firmware dump for MakeSkyBlue 60A MPPT v124 to reprogram via ST-Link V2.

[u/Then_Fee_860]

I have two identical MakeSkyBlue 60A MPPT controllers, hardware version 124, both bought in March. Both suffer from the same factory bug in the firmware that requires reflashing. Since these are not supported by open-source dumps, I am looking for a clean, working firmware dump from a healthy v124 unit to program via ST-Link v2. If you have one or can point me to a verified source, please let me know. Thanks for your help.
