The eeprom is a small memory storing some calibration values, normally nothing writes to it, it's used by the scope after a factory flash to restore the generator calibration.
But not all scopes had it, early ones like mine came blank, with the calibration only stored in the system flash.
Hantek would tell everyone to flash the scope, but that would wipe the calibration, system info...
If your version had a the calibration data in the eeprom, nice, but if not, they simply wouldn't care.
So run DSOflash and BackupBuilder. There're no other tools, it's all it needs to be safe under all circumstances.
If the scope hangs or crashes, then restore with latest Platform-tools, afterwards apply your "not-FULL" backup, will restore the important bits and it'll be ready.
DSOFlash and EE backup should never require restoring, they're there just in case.

About the new encoders:
Handling cursors/levels improved by much, its's very noticeable that the new encoders have twice the pulses per rotation.
A pair of quick turns and you're already at the other side!
...
Except in trigger-> pulse mode.
The pulse width adjustment works nicely all the way from 8ns to 10ms, up and down.
But from 10ms up, it randomly goes up/down when rotating too fast, so it barely moves.
I haven't found any other settign using V0 having this behaviour, so I'm wondering if this is a firmware bug or what?
It's clearly seen here:
