Touch screen firmware for Up Mini 2


I’m looking for the firmware of the touch screen of a Up mini 2 (not ES).
I asked the support for it, but I got (and I’m quoting them) “Sorry no have”! I’m still wrapping my head around that.
Anyway, here I am asking … Does anybody happen to have it? In that case, I would really appreciate if someone could share it with me.

Thanks and Regards

afaik the non ES screen cannot be updated (suspect its manufactured by someone other than tiertime tbh)
