I noticed that some PH6 board can not program using the procedure described above. Just use normal PH7/PH8 procedure. Also the backup of firmware can also try to use PH7/PH8 procedure.

i found the same for the non ph boards. i have a couple of them and i can only access them by using the ph 7/8 method.

Then it is OK, as long as you can access them. Does not matter which method you use. I only find one of my PH6 board need special way.

Found my CR4 box has $400000 to $500000 flipped.
The way to program is to flip the firmware and then program. No need to"go->break".
