No, it's definitely not the problem. Flashing the senior model logo to your 1300 only changes the Splash to D1340-50 from its original D1340-00. It does not involve the firmware at all, only enables the features provided by the fw which previously were blocked to the unit. All 13xx/14xx from 1300 to 1490 use exactly the same firmware. I've modified the splash to D1340-50 on numerous 1xxx which are all now running V6.20, including a US 1300 identical to yours.
Do as jimmy suggests and remove any old gupdate.gcd file from the unit's .System folder if present, and redownload the v6.2 gcd as the other file may be corrupt. You could also do the upgrade by connecting to WebUpdater or GarminExpress. Before you again attempt to upgrade, backup the unit, hard reset it or clear non-vol and also back up NV memory [rgn41]: [Only registered and activated users can see links. ] before any fw update.
