DAC Cable reprogramming FS Device not found

[longwaytojersey]

Hi,

I am trying to reprogramm DAC cables from FS (SFP-10G-PC01) they are "HP branded"

I can read the SFP just fine. But when i try to write anythign to it i instalty get Device not found / Erase operation failed.

Has anyone ever tried reprogramming DAC cables?

It seems like i have figured out the Device not found error.
Its probably due to not enough power for the cable.
When i insert the other end into a switch the write operations starts fine and the verification says ok but it just gives out a lot of garbage.
When i read the sfp again its not changed. So its probably pw protected.

If anyone has the pw for FS DAC please let me know. Im trying to bruteforce now.
