SM-T280 (samsung-gtexswifi) boot.img detected as invalid.

When using analyze_bootimg on the stock boot.img of the samsung-gtexswifi (I'm working on a port and will update the devices page when I'm done), it fails with this error: ERROR: File is not an Android bootimg. (, created: Mon Aug 20 07:49:33 1990, modified: Mon Apr 12 10:55:12 1982). Please try again. I know for certain that the file was not created in 1990 or modified in 1982. I was told to open an issue by someone on the postmarketos IRC channel. I think that changing the line in the script to detect whether the file is valid or not will work.
