How do I enable Strong modulation on NTAG216

This is the NTAG216 datasheet https://www.nxp.com/docs/en/data-sheet/NTAG213_215_216.pdf
Page 18 shows the config bytes for strong modulation.
You need to write an 04 into the first byte of E3

I was able to do disable and renable on an NTAG216 card using NFC Tools (pro)
This is assuming your auth byte(E3, byte 4) is FF (unlocked)…

Warning: I’m pretty sure you can essentially brick your tag if you write the wrong thing to the E3 page so to this at your own peril.

In NFC Tools, go to Other, then Advanced NFC Commands

Send the command A2E3040000FF
You should get a 0A result.

Rescan and it should be enabled.

BTW, testing with the card, it made no difference in read range with it enabled or disabled.
