In fact, you don't need to upload bootloader, you just need to use stlink to upload default. bin files, provided you use the correct firmware version and hardware version. Beginning address is 0x08000000. Good luck. After uploading, don't forget to disconnect all the power and re-energize, including 5V and your battery.
thank you! I was able to use an ST Link and copy the setup I had on my working board and then upload that to te non-working board, all through ST Link.
