Re: 8841 phone firmware

You're trying to downgrade, not upgrade, the phone might not even support that version, see a sticker on the phone or the box for the minimum version the phone can use. But no, that should not cause any issues with calls, depending on the exact issue, start by doing the basic troubleshooting for it.
