Troubleshooting #164 after updating the firmware


I bought a delta+ in October and it’s arrived in November, when I started the first prints it gave me no problem but after updating the firmware it started to give me error #164.
I tried to reset the printer but nothing changed, what should I do?


After updating the firmware I have faced crashing issue which was not allowing me to surf the internet. I have asked help from where I got many helpful informations.
