-I did not managed to discover any method ​that is able to recover a bad firmware without soldering the serial cable.+At the original time of writing, no method ​was known to recover ​//most models// from a bad firmware without soldering the serial cable. ​However, ongoing experiments suggest that **TFTP flashing is possible even without soldering** a serial port. The list of models and versions which have a factory U-Boot compiled with tftp enabled is to be determined. It's best to try it yourself because there'​s nothing to lose, but please do share your results at the respective wiki page.
