Vfd setting change xsy-at1

[ZombiWelder]

Gentlemen! Hope everyone is safe and healthy and not bored out their minds! I suspect I did something bone headed. I set up parameters on this seemingly generic vfd a while a go and it worked just fine. Now I'm trying to change some of the settings and it won't let me, the arrows allow me to choose the settings, but won't let me change them. I didn't set up any passwords in the first place, or did I?, I checked the password parameters p09 function, and that seems to be the only one the arrows will let me input numbers, so did somehow manage to lock myself out? Does anyone have one of these?
Thank you!

Two options,
Check P08, if set to 3333 the password is hidden, default is 0
Check P09 Input password should be 0

P77 is a parameter reset when set to 54321, it will reset all the parameters to factory defaults.

P08 and p09 are both 0000 and p77 can't change the input. The instructions don't mention any hard reset, is there one?

Not that I am aware of. You can email the dealer you purchased it from and ask them if there is another way to reset the DRO or change the programming data.
