Operate my device is nothing anyone really needs....
Doing a hard reset followed by the TT clear flash tool should enable the device to go through the normal upadte process.
Home will start with old NC and after a reboot offer the next update - continue until Home does no longer any updates.
If you still nedd DSA make a full backup using Windows Explorer, install the DSA NC into a folder on your PC - use the same NC version that runs on the device!
Now overwrite the content on the device with the content of the folder of the DSA NC.
