Something wrong with NFC 4k 7b reading #496

Closed RekordNadoev closed 11 months ago

Describe the bug.

firmware: dev branch, commit 036e09fd3a4a01ce97d04c6f7b30abb0b745c830 Reading Mifare Classic 4k 7-byte UID with all the keys are in the dictionary returns different count of read sectors every time. Something like attempt 1: "Keys Found: 80/80, Sectors Read 16/40" attempt 2: "Keys Found: 80/80, Sectors Read 38/40" attempt 3: "Keys Found: 80/80, Sectors Read 24/40" ... Every time sectors count differs.

(Unleashed firmware, dev branch last commit returns "Keys Found: 80/80, Sectors Read 40/40" every time.)

Reproduction

  1. Run: Menu => NFC => Read, with Mifare 4k 7-byte UID fob
  2. Get message: Multi-protocol card, "Read as NTAG/Ultralight" or "Read as Mifare Classic"
  3. Select "Read as Mifare Classic"
  4. Get "Mifare Classic 4K, UID: 05 87 A6 8D D0 F1 00, Keys Found: 80/80, Sectors Read 33/40". Sometimes more or less sectors read.
  5. Select: More => Save => enter filename => save
  6. See "?? ?? ..." instead of some data in the dumps.

Anything else?

The fob is cheap one from aliexpress. Unleashed firmware, dev branch, commit 364b33465416ea7f4bc1a71425fa5e4795c34083 returns "Keys Found: 80/80, Sectors Read 40/40" every time.

Today I changed FW from Xtreme to Unleashed and back to Xtreme for some testing. Now the fob reading is 40/40 sectors every time. It seems like it was some kind of glitch. Sorry.
