       hey fedi, does anyone have any experience with a NTAG216 (specifically a xNT) just. not allowing writes anymore? ​:boosts_ok_gay:​tldr: wrote a page trying to enable UID mirror and now i cannot do any writes, including after a successful password auth with FF:FF:FF:FF that returns a pwd_ack of 00 because. it was not set. password i had set was removed before writing anything (both using nfc tools on android)bit more context:wrote page E3 with bytes 44:00:DD:00 to begin an ascii mirror of the UID at page DD. reading the chip from NXP tag info or a memory dump with nfc tools tells me the mirror ends at E0, with E1 being empty as it should. page E2 reads 00:00:7F:BD which. seems weird. don't have any old memory dumps for the expected value but appears to be blocking all pages from being written.NXP tag info reports that pages 03 to E1 are "blocked, readable", page E2 is locked and blocked, and E3 to E4 are "un(b)locked, readable"nfc tools's advanced shell says "Error: I/O failure" when attempting to write (A2) to literally any page including E3 and E4 which say they're unblocked. the read page in nfc tools says it's both writable and password protected despite authenticating seemingly successfully (despite being still unable to write) with the "no password" default password of FF:FF:FF:FF. auth_lim has never been set to my knowledge.can provide specific pages and such if needed, just not attaching a full memory dump as i currently have my contact info that i don't intend on posting publicly written to it.
