Depends on what you did, as to what should be done to recover that function.
If, as part of recovery using Cure firmware, you subsequently formatted the file system and it then lost Voice Command it might just be lacking some essential files like SRD, ASR & SRX.
If it was a spontaneous loss of function regardless that all files were left in-place then it likely has a severe corruption in the nonvol region due to your updating attempts. My guess is it was that - due to you seeing "37xx" instead of "3790".
So you need to tell us exactly how it happened, i.e. what you did in detail before it needed to be cured, then a course of action can be undertaken. Regardless of the cause, if you haven't already done so please clear the non-volatile memory to see if that changes anything with the loss of model number: [Only registered and activated users can see links. ]
