Is it possible to flash Xz1 firmware on XZpremium like XZpremium single on dual sim?
I have flashed my dual with the CH single sim firmware and all gows on... Even the OTA updates from SONY

Expanding on that "No"..

The XZ1 and XZP have firmware that is signed by a different certificate.
So even if you try, the bootloader will recognize the certificate mismatch and prevent you from flashing it.
