Thnx for tips and trix.
I have now tried both methods above. No luck so far on my DM900 Sim2.30
I managed to get the boot screen for BA though.. Installed with command :dpkg -i /tmp/*.deb after first boot.
It is only 1 option: >0 Flash...
BA12.56 and rescue loader #103
I put some images in both ba/ba an ba backup folder...but to install them in BA the box need to finish boot or is it another metod to activate these images?
