) -- this is why I am asking for your advice. For Audi MMI which runs QNX as well you can connect to 20pin connector for IPL and switch device to update mode. Here is very similar connector (18 pin) and I think it is used for Initial Program Load. This revision has MMC module soldered to the board so I can not perform the same trick I did with my Uconnect(remove mmc memory and the system adjusts image state to recovery mode, so I can upload image to the device). If anybody knows how to switch to the recovery mode on device load - please let me know. I have a Uconnect with incorrect boot.sh file so the system loads and for some reasons software updater service does not start. The system switches to Media mode and this is the only screen which seems available. It is possible to select Bluetooth or Usb1/2 but nothing happens, software updated does not see any swdl.iso. Reset, engeneering menu, keys do not work.

if anybody has an idea how to temporarily disable mmc or write to the soldered mmc I will really appreciate any help.
