Niimbot B1 use compatible /all types of paper hack

I Hacked the Niimbot B1. I sniffed the SPI between the MCU and RFID management IC. SPI communication is active only when the lid get closed (that is when the paper is identified) or after printing a label. Meaning: 1) Lid closing: the paper is identified. Lid closing i detected wit ha switch. If we hack the switch (put in original paper with RFID tag) then lock the switch and change the paper. The machine does not detect that the paper has changed. 2) SPI communication is used to decrease the counter after a print. However, there is no check that the original paper is still there. :) The machine checks the paper only at the closing of the lid (Niimbot B1) Even Easier!!! SOLUTION: :D:D:D 1) Put compatible paper in the machine (any brand), do NOT close the lid 2) On the back of the machine on the outside, keep a roll of original paper exactly at the corner between the bottom and the back part of the machine. The roll as to be as close as possible to the machine (remove the labels eventually) 3) Close the lid while keeping an original roll on the outside in the back 4) The machine RFID will read the tag of the roll on the outside thinking that's inside 5) Put the original roll aside and HAPPY printing with compatible roll 6) Procedure has to be repeated every time the lid is open or the machine is turned on/off Tested on Niimbot B1 :) I have some logs from the SPI communication. Maybe we can find the encryption key to read the tags if someone is good at it.
