I'm looking to liberate my (non-WiFi) E4 after it was gifted to me as part of a redundancy and company shut down.
I believe that it has never been upgraded and is still on very old firmware.
Model E4 1.0
Part Number 63901-0101
Software 1.19.8
Looking though the thread, it is recommended to leave 1.19 as is, but I would really like to unlock the higher resolution and any menu/functionality improvements.
What would be the best way to go forward. Can I just use Buds procedure, or should I do an intermediate update first?
Thanks, in advance.
