Thanks mate, that much i know. But my concern is that because region 136/0x88 is presently populated on his Edge 1000 Explore and yet is absent from the intended flash. In other words, if 0x88 remains populated when it's converted to Edge 1000 is there going to be a problem if it should in fact be empty or have different content? That's why i asked if we should erase it in his current Explore. If it's unused in Edge 1000 then i suppose it can remain populated and not be a problem. But what if 0x88 in Edge 1000 does in fact have content?

Or am i jumping at shadows?
