I read through a few threads on here which give links to sites which give step by step guide on how to debrand the Nokia 5800. I have the phone from T-mobile but want to use it on 02 and i have followed these but cant even get past the first few steps.
I am using a Vista Laptop (which could be the problem, as many people say they were successful when using XP).
Anyway the part where i get stuck is where it first asks you to download the programmes and then to install it later. However when i click the download button - it asks me to open/save and there is no install button.
When i click on the save button it does download it, but then how do i install it. The programme i have downloaded is saved to my computer but it wont even open.
Does anyone know what i may be doing wrong or if there is another guide which they used, which is simpler. Otherwise it looks like paying £15 at the local phone shop to get it debranded, which is something i dont want to pay for when it can be done for free.
Edit: The guide i am following is: http://www.ariyako.org/2009/04/changing-nokia-product-code-using-jaf/
