Just to be sure you don`t get the no ca error i would recommend flashing the latest bootloader as well.
Place the box in flash mode > open a browser and first flash the bootloader > sim201_800HD_ssl84D_FOR_DRV20130607.rar (extract the .rar, .NFI is inside) > DON`T REBOOT.
Open another browser and flash the image -> OpenTS image 2.6 DM800 Sim2 SSL84D
Now reboot.
I also try to patch my DM800 HD like this, is it normal that I do not see any progress while flashing? It looks like nothing is happening. Wait a few minutes, that is the only thing that's commented before I patch.
