Broke me box? Idiots guide what
Hi everyone, guess they not everyone should be allowed to mess with cars.
Decided to buy a used Jb4 with the new jb connect. BMS has clear easy to follow instructions fitted the Bluetooth to the box (EWG v1 ) plugged it in the car with the obd downloaded Jb4 app easy everything worked could see my oil temp and everything could flick through the map all seemed good.
Then....... decided firmware update looks good so browsed the updates choose bmw F chassis N55 EWG downloaded and everything seemed ok, today a looked through the updates and found firmware for bmw b58/b48/b38 and thought that’s the up date for my car oops other one was wrong. (my car is a bmw f21 with the b58 engine) so downloaded the b58 update and the app couldn’t find the Jb4 hardware. Rechecked all cables and Bluetooth tried a different phone still no luck. The car will not run with the box and I have no way of resetting it as the Bluetooth can’t find the Jb4.
Can this be fixed? Or is it now scrap.

Thanks for any help.

You should be able to connect and fix the firmware but if not we have spare 2580 chips on our website that have firmware preloaded.

Hi Terry,
thanks for replying. I’ve looked through threads to try and find a how to guide, any links would be grateful.

Pop out old one with screwdriver push in new one, pretty easy. Notch faces JB4 connector like one you remove.

Absolutely brilliant service, chip arrived super quick to the UK. Thanks

I mentioned in another post my gauges aren’t work on the phone app could this be due to not having the obd connected? I don’t want to mess with firmware updates again and wreck the chip again lol

Yes OBDII is required for all CANbus data.

Everything has worked great after the new chip and obd connected now today tried to log on to the app and I get. “Error:access denied. Key invalid. Please login again.”
Any ideas I’ve had the phone almost touching the Jb4 and me phone connects to the cars Bluetooth

Thanks in advance
