The encrypted firmware v2.4.4 is stored as resource in the exe file.
Patching the exe to other lower encrypted firmware and fixing the size bytes, let the printer update with success massage, but the firmware is still unchanged.
Need to look deeper, maybe I miss something or checksum/hash.
]]>I had a problem with my Jr 1.0 with FW version 2.4.2, my every spool gave an error and I couln't do any firmware update.
I contacted XYZPrinting, and they gave me this file so I could update my printer.
It seems to update FW to 2.4.4
If you want, you can have the updater file.
Here is what the XYZ's support said:
