Hi krisostend,
1.3 is fit for all versions, and thus includes everything you need. No need to patch to a lower version first, at all.
Also, there is no install possible 'without 1.2' really, since thát is also included in the V1.3 patch.
The problem was not really with the intermediate patches and the fix wasn't to leave that out, but the culprit seems to have been something in the userdata that was cleared after the totally fresh install.
Hope that helps. I got your pm aswell btw, but I reckon this answers that question too.
Regards,
Fred
