Can't remove NTAG213 protection

Hi,
I'm using NFC tags based on NXP NTAG213.
Using NXP TAGWRITER I set a new password and than I try to remove protection, but the error "TAG can't be unprotected" occures
As I try to remove just the password, the AUTH0 register remains set to 0x27, so I can't change the configuration registers nor write 0xFF to AUTH0 - I/O failure occures.
Is there any way I can remove the password and protection using TAGWRITER?

I tryed it with multiple tags and the ffect is the same. At the beginning the tags are unprotected. The PROTECT bit is set to 0, CFGLOC is set to 0 too.
