Help needed here

So,

I tried to install TWRP but it did'nt work : i have "no command" when i acces the recovery and it actually destroyed my system.
So I flashed back the image "Global V9.6.4.ODLMIFF 8.1" but when i boot, the system ask me the scheme to allow the boot, so i put in the only scheme i putted in the device, and it tells me its wrong >_<

I need help on any of this points :
- Maybe a factory reset could be a solution but how do i install/reinstall any recovery (the base one or TWRP) ?
- Is there a way to disable this scheme lock secured boot ?
- Is there a default password/scheme on the device ?

Thanks for your time and your help

PS :
I tried to find answers by myself but i couldnt find any... This is my first post here, hope i didnt do something wrong !

You need to select the erase everything/clean all when using miflash. It will not recognize your password if you select the save user data.
