Howdy. I tried to downgrade from a P40 pro from 11 to 10. I didn't pay attention to N29 and instead of cust n29 I put N39 (the one for p40 pro +) It went on for a few minutes and entered recovery
Now I enter eRecovery. I can't connect it to the PC.

When I want to update through otg, it tells me that the system files are not compatible with the installed ones. I can't do anything anymore. Any idea?
