cannot upgrade sophos xg 210 SFOS 17.5.16 MR-16-Build830 to SFOS 18.5.2 MR-2-Build380

Question

Hey All, 
 So everytime I try upgrade the firmware of this FW it seems to just boot back into the V17 . 
 
 I checked out the migration logs and for some odd reason it gives me this : 
 nvram_get failed with -16 Old version is 17.323 and currentversion is 17.324 Database is upgrading to dbv17.324 Check migration for version dbv17.324 Applying migration for version dbv17.324 
 
 Are there any other logs I should be looking for ? It doesn't seem to see this V18

Hello there, 
 Thank you for contacting the Sophos Community. 
 You would need to check csc.log, syslog.log, applog.log, Postgres.log 
 Csc has to be put in debug mode, before you apply the upgrade to do so run the below command from the advanced shell 
 # csc custom debug 
 Additionally, check the time in the appliance is set correctly. 
 Regards,
