Unhappy New firmware update problems - 06-24-2020, 04:40 PM


I have N20 BMW 320i MSport 2018 ActiveFlex in Brazil with JB4 EWG Cable with JB4 Wireless Mobile Smartphone kit (2.4.4) on Iphone 7 IOS 13.5.1 and Map 6. After update to the new firmware N20_OBDII_EWG_7 some times the gauges is freeze. I disconnect and reconnect the app e the gauges back to work again. I was check all connections and looks be ok. Another point, some times during a log, JB4 change from map 6 to map4. After seconds, return to map 6. No codes and nothing like wrong. It is appear in the log parameters, but we don't see nothing what was exceed the limits. I was reinstall the firmware but the issues remain the same. I have thinking to make a downgrade to the old firmware but a cant find it anywhere. The app don't show anymore the lasts firmware.
Somebody can help? Therry, Can you heard me?
Tks guys!
