@fact - Thanks for confirming, thought i was going mad when i returned it back to normal and it didn't work.

Unfortunately the "tool" for un-encrypting the nsp_data_b file is not available, it was just by chance i noticed that it had grown in size when comparing the backups i had made.

The tool is available but it's not public domain. Siglent's 3DES decryption of your "original" file is attached (raw).

<?xml version="1.0" encoding="UTF-8"?>
<sn_backup_root>
  <factory>TRUE</factory>
  <pro_mode>TRUE</pro_mode>
</sn_backup_root>


A typical nsp_data_b contents can be seen here.

Easy way to overcome losing telnet when updating to 1.2.9.3a is to create your own symbolic links for the telnet deamon.
e.g.
Enter "mount -o remount,rw /"
Enter "cd /etc/rc0.d"
Enter "ls -al"
Examine the telnet symbolic link, K10telnetd in this case and create your own with a different number, 15 in this example.
Enter "ln -s ../init.d/telnetd K15telnetd"
Enter "sync"
Replicate this for the other rc directories .
Restart the analyzer.
After this, you can safely update to 1.2.9.3a while preserving telnet access.
