For the people who still have 1.5 and under, why dont we come up with a modified 2.0 update that only adds the features of 2.0 and not the entire firmware? We would have to know what files to replace and which ones to ignore. If the updates really do erase completely before a flash then maybe we could tell it not to and just to erase and rewrite certain files. I do not have sufficient PSP knowledge to actually know what I'm talking about so, go easy on me. Just an idea.
