I let someone have my 212 sometime ago.
It has now returned to my fold.
It has TDB f/w 1.15.
I have tried to update to 1.24.
But it will not take.
Have tried MCSE patching (readspeed, rpc1, bitsetting). This didn’t work.
I wonder what I am doing wrong?
Edit: What a plonker.
I edited the f/w, but forgot the flasher part.
So it is all go now.
