Is there any way to check for the blown eFuses? I'm not thinking about dashboard versions but a way to check through reading the NAND or something like that. Perhaps getting a certain error when trying to use JTAG?

Best regards

If you have your CPU key to decrypt the NAND you can see when the LDV changes.

Ok. Thanks man.

In this case it doesn´t help much because I don´ have the CPU key and can´t get it. I have access to af lot of banned boxes with dash 8955 and I wanted to test if the eFuses is blown in all of them. Just to see, if there were a case of a dash 8955 without a blown eFuse. I know it is properly a waste of time but I would like to know for sure.

If they are all updated to an 8XXX dash then the Efuse is blown on them all.

Yes I know that. But I also know that it is due to a software update and software is not always 100% reliable. That´s why I am looking for another way to test it without seeing at the software version. Or one who can explain to me why it is 100% sure they are blown when using 8955.

I´m nok looking for a magic way to fix it.

Trust me, if the dash somehow got updated to 8xxx without blowing an efuse, the console would not boot.

I don't pretend to be an expert on the workings of the kernel but I do know there is a "is eFuse blown?" check in the update process. Much like the check that causes E80 if you update Blades dash to NXE with r6t3 removed,
