Trying to flash QMK/VIA firmware - HELP! I think I might have killed my keyb! (feddit.uk)

I bought a cheap Durgod Hades with the intention of sticking the QMK/VIA firmware on it.

First issue was getting it into the bootloader - the instructions didn't seem to be working, so I was trying different connection points and implements until it finally kicked into life. In doing that I suspect I may have killed the STM32... but I'm not sure.

Using dfu-util I've tried :unprotect:force and :mass-erase:force to try and recover it, and also downloaded STM32Cube to see if I have more luck with that.

dfu-util, no matter what I do, hangs at the erase point 0%. Eventually it times out with an error.

STM32Cube connects to the keyboard but complains it's in read-only or reset held. If I try again with the suggested Read Unprotect option it says I need to power off and power on the device, and the cycle continues.

So I think I've somehow bust it, is there anything else I can try before admitting defeat and getting another one?

Im not too familiar with STM32, but I think this should apply on all QMK-based device: is the default program still accessible after you disconnect then reconnect the device?

If the answer is yes, then your keyboard is probably fine. That said, I am afraid I can't help you past that.

Add: If you have access to Discord, you might want to hit QMK Discord server and see if there are any community member that can help you with the issue.

Thanks, it wasn't running the default after unplugging and replugging. I ended up replacing it, although I still have the dead one as I'm not sure what to do with it!

Oh, that's rather unfortunate :(

Here's hoping the replacement works swimmingly
