Hi, some SFPs allows for I2C transmission only after power up - second try will give you timeout (REVELPROG will try to restart SFP in such case and 3rd try may or may ot work) but when you unplug SFP, plug it and click read - it should work. You can also try "NoDelay" option (checkbox).
For brute force password if auto-adjust does not work you have to set write delay manually - try 10ms. If it work - try 9ms, if it work, try 8ms etc. But please remember about above - unplug SFP, plug SFP and then click brute force (or disconnect usb power supply from adapter and connect again). Second try may be timeout, 3rd try may work again (if SFP restarts success), 4rd may not work, 5th may work etc - I had this issue with some transceivers
