I'm not specialist in transceivers but one important question: does brute force changed manufacturer name when it found password? (it should write password in manufacturer name field)
ArT wrote:If yes -> probably there are few passwords and one password is valid only for one operation (you can reprogram qsfp only few times) - in such case you should find also other password if you continue brute force. If it find second password DO NOT disconnect transceiver from adapter. You need to rewrite it in the same session (if you disconnect power from it then password will not be valid anymore).
