RE: VW Mib2 recovery
if the unit can be turned on the rx tx output will definitely work

rx and tx must be in the cross - it's not in this picture

RE: VW Mib2 recovery
if the uart works:

1. disconnect the radio from the power supply
2. insert the SD card with the update into the radio
3. insert the jumper into the unit board
4. connect the radio and press 2 on the uart (emergency update)
5. remove the jumper

RE: VW Mib2 recovery

RE: VW Mib2 recovery
If you do what i wrote the unit will be restored. Connect the UART to trace RX and trace TX.

RE: VW Mib2 recovery
I already tried connect RX on UART to TX on Quadlock and TX on UART to RX on Quadlock and then i get no signal in putty? The UART is on as I can see a red light on it but no green blinking connection

So i dont know what i am doing wrong sad

I also tried reverse TX to TX and RX to RX and still no communication

If i connect to rx/tx imx6 on mainboard i see alot of scrolling info in putty. Im newbie and trying to learn how uart works
