Describe the bug.

Issue with NFC Tag Reading and Writing on Flipper Zero with Xtreme Firmware

Problem Description

I encountered an issue with my Flipper Zero running the Xtreme Firmware, where I am unable to read or write NFC tags successfully. When attempting to read a new and empty tag, the device reports that only 133 out of 135 pages were read. However, I can successfully read all pages if the tags are unlocked using the password FF FF FF FF wich I found online.

Additionally, when trying to write to an NFC tag, the device indicates that it is still locked, and there is an issue related to Auth 0 (refer to the attached picture).

Steps to Reproduce

  1. Attempt to read a new and empty NFC tag.
  2. Observe the reported read result (133/135 pages).
  3. Try reading the same tag after unlocking with the password FF FF FF FF.
  4. Attempt to write to an NFC tag.
  5. Observe the reported lock status and Auth 0 issue (as shown in the attached picture).

Expected Behavior

The Flipper Zero with Xtreme Firmware should be able to read and write to NFC tags without encountering issues related to incomplete reads or authentication problems.

your card is locked by the lock bits. even with the passwords for all the pages you cant do anything. Those logs are useless btw, ignore them. They are referring to your actions via qflipper

explain how you are attempting to write to it.

I go to "NFC". then to "saved". Then I choose a saved nfc file. After that I click on "Write" and hold a nfc tag to the back of the flipper and Then the message apepars that you can see in the first picture

learning to use google might prove fruitful. https://www.google.com/search?q=write+locked+ntag215+with+flipper+zero https://www.reddit.com/r/flipperzero/comments/18e48gg/flipper_thinks_all_ntag215_cards_are_password/ https://github.com/flipperdevices/flipperzero-firmware/issues/3281 https://github.com/flipperdevices/flipperzero-firmware/pull/3285

the issue is resolved and merged into the firmware. it is already available in dev builds, and will be released in v53.

technically not resolved in a stable release however, so i will reopen and mark as pending release.
