I sounds like you do not need to shift the levels from the kindle TxD to the adapter RxD.

Hello,
It is now in diags mode. I just kept it for whole day charging and ENABLE_DIAGS file was on the USB drive all the time. I found very useful option for me when I discovered what is available from the diags menu. I may see also everything that I am doing on the serial console output:
The most interesting option for me is Enable USBnet. Probably, it would be enough for me to just download all system's startup scripts and compare them with my backup version.
BTW: The Kindle does not react on my serial console output even in this mode. So, it seems that my problem is hardware problem. I will check my adapter's and lever shifter's TxD line when I will get an access to digital or at least to analogue oscilloscope.
