My Galaxy Flex 50 may go in unrecoverable error condition upon certain COM5 failure caused by the SMS connection. At times those error conditions can be recovered, but not always. In other cases the log shows the com5 problem starting but never resolving. If this happens, the only way to reactivate sms functionality is to switch everything off and then on again. Reset (Menu 51-17) does not help, whichever password is used. The delay for sms connection errors has maximum value, 360. Can anybody tell me if there is a way to reset those errors without powering off the installation?
