Guess that you have a phone in this status when you attach it:

error while reading security units
SECURITY UNITS CAN'T BE READ !
DAMAGED FIRMWARE/GDFS OR EMPTY PHONE
erom_readvar: error reading unit 1/851

This phones has been tampered with Dreambox....
To continue working with Setool you must Repair the phones with the correct script (I attach the DB2012 and DB2020 scripts)
Instructions:
-Check signed mode
-Use COM interface
-Add the script in Misc files and press Write Script
Then you'll be able to work the phone as usual
