It Seems did after installing the new firmware MGG/MH8
no longer be viable to make a downgrade to a previous firmware through odin, flash fails.
Even through flash ROM-based firmware than good Because even if the flash is successful
you will loose all of the system sounds so calls are impossible …. even advise you to wait more clarification before upgrading.
