Factory reset YL20C/YL80C EP 2 PRO ENGWE

[tmmyskinner]

Hi I have bought an engwe ep 2 Pro electric bike and it has a yolin

controller on it but I cannot factory reset it with -/i buttons, it just flashes. The DEf screen doesn't come up. My controller goes from 01p to 019p and I would like to know what all the programs are for. My manual is for the YL80C but here's a picture of my controller numbers.

I would like to factory reset or put the programs on the right settings if possible.

Could you help me please

Would also be interested in the Manual/Programs explanations since the YL80C does not apply 1:1, on that one there were 2 different menus and every menu entry had some kind of letters to explain what it did. This one has p1 to p19 like mentioned above, and some just have the option to select from 00 to some numbers that are not clear what it could be.
