If I lose keys for widevine I won't care I just would like to know if this or any remedy is possible when stuck in APX mode after a wrongly flashed system.  My device is past the warranty date so an RMA is not an option.  Even if I could possibly flash linux4tegra it would still be better than having a bricked device stuck in an unusable state.  Any help is immensely appreciated.

I don't know but am interested also. I think I asked once and was told
that you have to solder things to the shield or add a separate board
to get access to UART and I lost interest at that point. I need to
practice my soldering.
