Hi, I just updated my JB4 to the new firmwareI believe its T22.
I turn the power without ignition. My phone is iphone X, IOS 13. Newest app.
Everything is good, when after upodate 400 files and check the sum JB4 is reboost,I also change the map from 2 to 1.
Today when I start the car it become very strange. And I remove the JB4 before I leaving. But it give me a CEL anyway. The car tremble very bad but after I open hood and restart(without JB4) it become back and after 10km drive CEL is gone.And JB4 is aways waiting handshake that time.
Wonder know how you guyes update your JB4? I have this problem before and change a mastchip,but why it happen when I try to update? It do show it updated and I can switch the map after that?
