Hi Alex,
Can you extract a .senc file so we can actually determine what chip version you are on.
You can select the v1.05 target and then go straight to Pro screen. Put device in ROM and read out the senc (you do know how to put and take the device in/out of ROM mode right? ). Then execute FW and quit EVSW.
As long as nothing else is done with EVSW this is safe.
thanks
Onyx
