I have Two N905 + One N905B Kobo's Touch. N905B, as all good children with SD card. Installed XCSoar and i happy. Almost happy (*).

And remaining two N905 bricked after install "Dual Boot Android".
I connect to motherboard via UART-USB adapter and I got some log:

I think the problem here somewhere:

bootcmd_SD=run bootargs_base bootargs_android bootargs_SD;load_ntxkernel; bootm
bootargs_android=setenv bootargs ${bootargs} init=/init androidboot.serialno=20030394,b3f7fdff960a45bebbc97f7e0266bf42
bootcmd_recovery=run bootargs_base bootargs_recovery bootargs_android;load_ntxkernel; bootm

U-boot cant find image (android boot image?) And seek in on uSD card, which is absent.

Also i can load image files trough kermit or ymadem protocol via serial.

Who say how to correct environment for loading.
or
Send me image file for load to fixed memory via serial?
Start addres?

(*) Why almost? I cant find pads for serial line.
I try 2 subscribed pads, remain one groups pads nonsubscribed.
