About install apps

[katorce]

Hello.
I'm new in that forum (and a little noob in samygo), and I use some samygo apps. I'm from Spain and actually I use that apps:
Bigger yellow Font (one version, I don't know what)
PVR+ (3.0)
Outliner
Screen Resizer (Because I never understand the Aspect Radio app and I never get it work)

If I want to have BYF and Outiner both I've to first activate BYF and then outliner.
But I would like to charge that four app at the TV goes ON. I know it's possible but I read it's hard and you could get a Brick TV.

There is a tutorial (or video-tutorial) or something similar?
Have I know to programme, linux or something similar at high scale?
My TV is a B-series with a firmware I couldn't remember and I don't konw how to look it, but the firmware was gave to me by the admin of the samygo facebook group.

Thank you guys!
