Look inside your garmindevice.xml to confirm your HWID is 2267
<PartNumber>006-B2267-00</PartNumber>
<SoftwareVersion>590</SoftwareVersion>
<Description>DriveSmart 50</Description>
Then go to software/universal-firmware-patcher-for-protected-garmin-devices-t17987-420.html#p175604

The thread you posted in is about unlocking Garmin .img files this thread is about Patching devices to use unlocked maps,unfortunatly yours cannot be patched.
For a few years newer device's firmware could be patched (determined by their HWID) to use unlocked maps, since the DriveSmart 65 the firmware has been encrypted on these later devices.
Unfortunately it looks like Drive, DriveSmart 52,53,55,65,66,71,76,86, zumo XT ,zumo XT2, Alpha 200i, Montana 700 ,GPSMAP 67 & 67i are all in the same category.
No solution as the Universal Firmware Patcher does not recognise the new encrypted format.
