Updated JB4 While Driving, Big Mistake - Need Help

[Striker's Stinger]

So I was driving on the freeway today and noticed my JB4 only displaying the Map setting. All other values were at 0 and didn’t budge. I attached a picture to show. I figured I needed to update the JB4 firmware so, like a complete genius, I decided to update it while driving on the freeway. The second I clicked update firmware, every single light on my dash popped up and as I tried to accelerate the car wouldn’t respond. I tried flooring the throttle just to see and my RPMs went up to only 2K. I pulled over on the freeway, I had to since my car was decelerating and no near exits. I waited for the JB4 to finish the update and turned off my car after the update was complete. When I turned it back on all the lights were gone besides my check engine light. I was driving to work so no time to check was the code was. The car drives fine now, but now I’m absolutely terrified to even hit the gas. What the hell happened? Any clue what code may pop up from the CEL? I have PTSD from my own stupidity now. CEL remains on. The JB4 after the update didn't fix the issue of all zero values.

Any advice and info would be much appreciated as I’m still a bit shook from the entire experience.

First of all, your gauges probably didn't read because your OBDII connector wasn't connected properly. The jb4 display (and logs) get most of the parameters via the OBDII connector.
During the FW update, the jb4 itself goes dumb, so this will screw up everything if you try to drive it while updating FW.
You can certainly update the app, but don't try to update the FW.
Since you didn't shut the car off in the middle, the update probably went through just fine, so I would say your are OK. If you have a CEL stored because of it, make sure the ODBII connection is working, and use the "Read Codes" function (just have the ignition on, but engine not started), you can zsee the code and also clear it (code won't clear if engine is running.)

Just checked and my JB4 port is not connected to the OBDII. It won't allow me to read codes and says error. I had my LED steering wheel installed last week and seems they connected the OBDII to that and never told me they unplugged the JB4. I think that'll do the trick. Thank you for your help!

Not sure what you can do if both the steering wheel and jb4 need the OBDII port.
I tried to play around connecting OBD port under the hood to my jb4 but could never get it to work.
