HowTo: Fix your ESP32 C3’s Bootloader after you messed it up
October 28, 2025 @ 01:26
When I was recently playing around with my CanGrow Firmware and trying to load it to ESP32 S2 and ESP32 C3 boards, i accidentally flashed the wrong firmware binary to my ESP32 C3. And to make things worse, I also wrote it at the very beginning of the flash and overwrote the existing bootloader living there.
The result: An ESP which I can flash with my program, but it wont boot it at all.
