Hello, I got the "wrong text" message on the keypad and pressed * and 1 together but still got the "wrong text message" after downloading completed. I tried to upgrade the vocabulary as i thought it should be corrupted, but the upgrading process remains in 0% and after a few seconds this message appears: "Vocab upgrade encountered errors" and then "the operation was canceled".
The system is Comfort ultraII
Version 6.005 (upgraded from 5.217)
Vocabulary number 0
ucm/eth, ucm firmware 5.212
