No EEPROM data #43

450mc chips use SHA-1 protection, so you will need to know the HMAC secret in order to write back to it with a RasPi. |
Is there any possibility that the fortus 250cc Chip working with 450mc ? Any Ideas ? |
maybe if you have Fortus 250 try to swap eeprom reader with 450 if they have same connection. but the main problem is SHA-1 protection. |
With an fpga you could brute force this similair to bitcoin hashing and get
the encryption key pretty quick.

Have been using this tool for fortus 250mc and dimension series for quite some time .
Now, I was trying to refill a 450mc Chip, I was able to read and the id is "b3-xxxxxxx" usually it will be "23-xxxxxx" and it doesn't have eeprom in it it has "rw" , when i tried to read rw it is showing " ff ... " only. so i was not able to get the eeprom data copied for editing the material percentage
Is there a way refill the chip?
I am using Rasp pi 3 for refilling the chip
