Welcome to the forum mpboy
well I am sorry we do not do here what is shown below, this is a self help forum however most stb's have 'similar' basic methodology, there are a number of howto's on the various forums on this board which may help you understand a little but basically you will need some loader software and then some firmware either official or unofficial, you will need a pc or laptop and cable connection between pc and stb. Each individual stb has it's own instructions but this should only be undertaken in the full knowledge that if you do something incorrect you may have to bin the stb.
