The samsung algorithm is pretty primitive and has nothing to do with BCH (which is the algorithm used, for sure).

It's more about how to retrieve the parametersthe algorithm uses. There are a lot of things that you need to know, e.g. block size, ecc size, bit order, polynome size, number of passes of the shift registers, input/output scrambling etc. Maybe rs8191 can give us some hints <img src="images/smiles/icon_wink.gif" alt="Wink" title="Wink" /> ...
