I was hoping to convert the unit to the facelift software version and I got stuck with red screen and #Emergency Download, the only way to turn off the radio was by removing the QuadLock connector from the main unit. ℹ️ I’ve created a custom update to restore stock swdownload app instead of the patched one. Red screen was gone, VW logo appeared but the unit was now in boot loop and every 30 seconds it rebooted. I’ve prepared an SD card with previous firmware, inserted it in SD1 port, connected USB-to-UART converter to the QuadLock, opened the unit and shorted two point with tweezers while powering the device. This way I was able to see #recovery menu on my PC, and by selecting “2“ I choose emergency download mode. Powered of the device, waited 10 seconds, powered it back on, the unit started in Emergency Download mode, and immediately detected the SD card with firmware files. After 30 minutes or so system was restored to stock. Component protection was not triggered, factory installed FEC/SWaP codes were present and valid. 🔌 PuTTy Serial COM with 115200bps; level; Rx to Tx, Tx to Rx, Gnd to Gnd. 💻 Firmware used to restore: MST2_EU_VW_ZR_P0254T 🚗 MIB2 Technisat/Preh units can be found in VAG cars like Volkswagen, Seat, Skoda. 🚙 MIB2 Delphi and Harman units can be found in VAG cars like Audi, Sear, Skoda, Volkswagen, Porsche, Lamborghini.
