Honestly one of the first things I do when I get issues with my xsiid is this
The commands are:
A20400000000
A20500000000
A2060000031F
A207D1011B55
A20803666F72
A209756D2E64
A20A616E6765
A20B726F7573
A20C7468696E
A20D67732E63
A20E6F6D2FFE
These can be run one at a time or as a block depending on how your app of choice works. I recommend NFC shell on android.
This will clear the xsiid and sent a ndef uri record pointing to dangerousthings.com
