from root wiki:
Will you release the source code?
At this time, we are not disclosing the vulnerability we have exploited.
That doesn't seem fair! Android is about open source.
In some senses, we agree; but at times, a tradeoff needs to be made. Releasing the source code for this, we believe, would compromise the greater ability to unlock devices like these in the future. Given the choice between sacrificing the liberty of running code on our handsets and the liberty of reading the code by which we unlock it, we feel that the millions of handsets are more important. It is unfortunate that we must make such a choice, and we look forward to the day in the future that no such decision need be made.
ie progress for OG EVO?
