So I think I screwed up my JB4 now. I tried downloading the latest firmware from the app and I.think chose the wrong one. How can I get back to what the unit was shipped with? E70 N63.

Edit: I tried the X5 firmware from this post but it's still not working F Chassis N63 JB4 - N54Tech.com - International Turbo Racing Discussion JB4_E_X5_1B.hex
