i cant get the new software on it because boot loader is bad. A friend of mine has a st link , wilt try flashing new boot loader … thanks for the help, now i know whats wrong
I would love to assist you with this problem via team viewer you don’t need ST-Link to flash it, just get the right firmware file and re-upload it.
I am available now, DM me if you need an assistance now
