content: I thought I might be able to help with another EEPROM dump to look at, but we still use the old MTS-2000 model at work (which incidentally is as slow as a wet week to use.....)

content: you need to locate the eeprom, usually it's a DS2433.you need an eeprom programmer, I use REVELPROG IS.Dumping is easy, understanding how the licenses are written is difficult. I haven't figured it out yet.

content: Quote from: pateanatale on April 28, 2025, 12:42:50 pmYou have to investigate where possible checksums/CRCs are. It's not only finding out where the option bitmask may reside.Look at this comparison.

content: I know, with the help of AI we found two CRCs, a CRC8 and a CRC16 as described in the DS2433 eeprom datasheet.CRC8 is between 0x000 and 0x01F, CRC16 is between 0x020 and 0x03F. The remaining bits I believe have an external checksum.I have three types of dumps with different options enabled, lines from 0x000 to 0x01F and 0x160 to 0x17F are the same, the values ​​do not change.the data between 0x020 to 0x3f and 0x040 to 0xfff are related, I tried to cross-reference the data but it does not work, I have to copy the entire eeprom to another.

content: the CRC8 is F3 in 0x00E in all file.the CRC16 is 60 F6 in 0x03A and 0x03B

content: Quote from: pateanatale on May 10, 2025, 01:02:27 pmSorry but that doesn't make any sense. You don't have CRC in the middle of buffers being hashed (99% of the times). Also, positions 3A+3B are 00 in one of the files... Definitely not CRC.Attach here the 3rd file that you have.

content: in the second file the crc was calculated in other positions, now I don't remember. I'm not familiar with hex or assembly, these calculations were done by AI.

content: he had calculated them according to the datasheet data, doing the counter test it worked, it gave correct result. now I'm trying to create a key gen from the firmware always with AI. but I don't understand anything, it's too complicated for me.
