This article provides working instructions for end-users to perform a firmware recovery procedure on their printer. The firmware recovery can be used to restore functionality to a bricked printer.

Note: This procedure can be done safely for users of the Ultimaker S3 and Ultimaker S5 (mid 2020 version). If you have an Ultimaker S5 (2018 - mid 2020), then there is an extra safety procedure that must be adhered to. Please contact Ultimaker Support by raising a ticket above for assistance.
