Data data can be recovered in DFU mode by Apple authorized service.
If DFU revive can be completed, that is viable way for data recovery.
Don't try restore, as it erase data!

I’m confident the board will accept a DFU revive.
What I’m trying to determine is the correct repair path for data recovery. Should I be transferring the T2, T2 ROM, and NANDs to another board, or replacing the CPU?
I’ve tried both approaches in the past, but I always end up with the same result. It feels like there’s an additional step I’m missing. Do you happen to know what that step might be?
A DFU revive after the component transfers doesn’t seem to clear or rebuild the ME region properly. However, if I perform a DFU restore, the board functions perfectly afterward—but, of course, all of the data is lost.
