need help to unbrick SB6121
Hello there! My SB6121 is bricked, I am trying to restore the 8mb dump on AllFlash, programing goes well (at least usbjtagnt is saying so) but when i turn on the SB6121 the situation is the same... all lights are on, ethernet is not recognised.
Is there someone that had this smiliar problem!?
I need to mention that i programed the chip also with SPI Programmer, but the situation reminds the same!
I need help, thank you

You need to do cmpram after the program to make sure the program is correct.XonA wrote:Hello there!

I also made an AllFlash backup but, after reading a bit, I am not sure the reading or the file is not corrupt somehow. Its an 8192KB file but, I don't think I ever wrote it back into the modem to see if it still functions as it should. So, the question would be.....does anybody have the full dump backup for an SB6121 modem that they are willing to donate? It would be nice to post one in the Download section with the other donated backup firmwares.
I guess that would include the MAC, serial, and certs but, Im not sure it matters if that is copied several times over since the MAC and certs would need to be to a local subscribed account to get online. So, that would allow users with a bricked modem to start from a known baseline and then go from there.
