Sorry , I didn't know that link doesn't work. For install your oscam you need oscam arm architecture for your box.
Ok, it accepts my oscam 11783-r801, what should I do next to keep it and update it to the new Oscam 11784 without having to do the installation again and search for the new Oscam
Is it opening channels ? Do you have pic ?
when you need to update just look in
Oscam Mipsel & Arm
download oscam/oscam emu for ARMv7 box.
Vu+0 4k has an ARMv7 chip (look in information/about screen).
unzip from .ipk, the oscam for ARM, and replace the old one with the new one & give it attribute 755. Restart.
