Read this first.
As for the “Boot Failure - Entered Update Mode” message, you are aware that it is documented in the Release Notes. This is due to the major changes to the Helix Core and can take a while (brain transplant), but wait for the message in HX Edit stating the device needs to be reset - Click Resume and wait for the second part of the update to finish. When the install is complete, your hardware should auto restart and go through the “Rebuilding Presets” routine - once again this could take a while. Now you can perform a Factory Reset on your unit and you can check out all the new factory presets (again, refer to the notes).
That's from this. You need to fully read this before you proceed. You can skip the part about what is new.
Here's your factory reset options. The 9 & 10 option is what you should do. It resets but nukes everything. I hope you did a backup.
