Thanks kasrola, you are a honest man too. By the way I was not referring to you. I wrote in general. Yes you are giving a good example cause if one try and experiment and errors or damage is caused or occurs one can not blame any file guy. When I started about ten years ago on ISO card which I had with my first Nokia 9200 I tried to experiment with the first card programmer I burnt it out that minute. It was £100 and I had to go and buy another that was £200 down the drain. It was my fault cause I rushed and did not read before to make myself know what I was doing. I gave up and after a month I started again and I worked on Nokia, humax, echostar,cards and cams still I made some mistakes in the beginning but I learned a lot from my own mistakes. I was not happy just because I could send firms to the stb but I started working on how to get back the errors and mistakes and that what made me confident. I use to wait for files on forums to work so again I had to learn how to edit all the files that I work with. I have even finished to install dishes so that I could buy more things and equipment. Keep in mind that what one knows is never enough.
My advise is never to give up. Try but go slowly and always read instructions more than ones if you have to.
Good luck
