Does anyone know how to downgrade the iOS 11 ba...

You can't downgrade anymore with or without a computer.

Apple only signs older versions of iOS for a short period of time after a new one is released, and at this time iOS 10 s no longer signed so cannot be installed.

During the signing period iTunes is required, there is no way to do it without iTunes.
