The NANJG’s firmware can’t be read out since it’s protected against that. There’s no error message, but trying to read it out only results in garbage data.

So, how am I supposed to return genuine nanjg software in case I mess up something? Or even how to delete/overwrite it  then!!! That means that once the sw is changed there’s no going back, mode selection, soldering different stars with BAT- becomes useless!!!

I have just made a similar firmware, available here .
