SC670 Mpc2550

good night, I have a machine that takes a lot to call, when it appears with code sc670 and I can not enter the technical mode to cancel, can someone help me?
I thought about updating it, would that solve it? or is the BICU board bad?

An SC670 code is a controller error. You can try unplugging the hdd and see if it will boot with limited functions. You may need to replace the controller board and the ipu as a set.

Yes sounds like a controller issue, I would first try updating the fw, if it will not boot off your fw sd card then I would replace the controller.

However you could also try "reseating" all the controller connections, inc ram etc nothing to loose.

the problem is that it is not letting me enter the simulation to clear the settings

I downloaded the firmware update, I'll try to do it today

That is because is a controller boot error, not a fusing error. The error code cannot be cleared through SP mode. You must correct the cause of the error. Once you have done so, the error will be gone.
