+## Flashing back the previous image
+If you somehow fail to setup everything but keep your previous image. For an esp32 this is the way to reflash back the image:
+
+    python -m esptool -b 921600 write_flash 0x0 .\Downloads\tb.esp32.bin --flash_size 8MB
+
+Resulting in the following example output
