Hello guys!

 

I have android TV box called netup with PCB called S905X inside of box.

First of all i installed TWRP. Then i tried to use manuals, but my PCB doesn't have reset button. In android i couldn't press "update" and run zip script. Software didn't see any zip. Screen was empty.

 

Then i somehow killed android and got a brock with TWRP. Then - i found zip file with libreelec firmware. I uploaded zip file TWRP-LibreELEC-S905X-1GB-8.2 and pushed update >> boot partition into TWRP.
And it wrote this zip to boot, and now i have libreelec and it works.

 

But i need armbian (i would like to have small server for IOT, not Kodi).

 

Please give me some advises how i can flash armbian to my PCB without ability to press reset button ?

Is it possible to compile the same zip which i can upload via twrp ?
in that zip i have:
folder META-INF
folder system
dtb.img
kernel.img

Thanks for your time. I hope somebody would help me and give some basic ideas what to do next?

All the 'install multiboot' process is doing (whether through the reset button or update app) is running the uboot script aml_autoscript located in /boot in the image.  If you can get into uboot via a serial interface you can run these commands directly.  They are setting uboot environment variables to tell the boot process to look for armbian before trying to boot the android partition.
