Error in Xperia XA2

Hi, im trying to install Sailfish in my Xperia XA2 device, the problem is that i made all except having installed newest Android version, i tried in 8.0 and it made an error obviously.

The question here is, I tried to quit the debugging mode for installing 8.1 and with the flashtool it says that i must quit MTP mode, how can i do that? Or can i install 8.1 from a rom?

I installed sailfish onto android 8.0 on my xa2 ultra. I didn’t face a problem

Usually quit mmtp mode by tapping notification about USB mode end tap something else besides ltp like charging or whatever
