Is this loop from the 1st stage bootloader? If that is the case, you only need to flash the 2nd stage bootloader. You can get prebuilt binaries for that on github.com/espressif/esp-nutt-bootloader and then from NuttX you can flash with make download ESPTOOL_BINDIR=... You can also build it yourself if you want. Please check the documentation, there should be direct links. (Using just a phone now sorry)
