How can I get Brown Certificate without using Omnius

Hello community.

After seeing my C510 double screen fail, I looked in 'Saint' Google for some results and ended here. After reading a few tutorials I fix'd my issue, but a new doubt came to me after looking in the download directory (patches actually). How can I change from RED to BROWN certificate without using Omnius (I have no money to do this). Using Aerix method (as i found here) won't work because of the dead program.

So my question is, again, How can I do this without paying for?

I don't want to buy a new cellphone, because frankly I don't like touch screens in a mobile phone. Greeting to all of you!
