XD I just read that yesterday.
You have a 3000 09g am I right? You have downgraded that one once with davees downgrader to 6.20 right?
You upgraded with the special upgrader that brings you to 6.60.
Well you can't go anywhere anymore. That's it, its over, stay with 6.60, its not that bad.

I read that some people got stuck at 6.20...

He was primarily concerned with avoiding bricks while in the beta testing phase (I was a tester), so he didn't have people check if update ability was still possible.
Davee was theorizing in that blog post that updating would work on 09g 6.20 -- but he was mistaken. I tested on my PSP to see for sure and I get the same IDXFFFFFFFF error as everybody else.
I'm sure Davee will find a bix for the bug soon enough so I'm not really concerned. Besides, having a perm hacked PSP isn't a bad position to be in by any stretch of the imagination. [IMG]
btw--Another good way to look at the situation is this really is a permanent hack. Nobody can get rid of it even if they wanted (good luck accidentally getting rid of my cfw, little brother)! . [IMG]
Truly permanent indeed!
And here the downgrade story:

A little caution: There are reports that TA-095v2 (there are two 09g versions) motherboards can't re-downgrade to 6.20 after escaping its clutches once before.
It's always something with these downgraders.
How to check and see what you have:

So to summarize it, your index_09g.dat in flash has been renamed, then renamed again and somehow the whole construct has been patched to work again.
I wouldn't wonder if you could not update to anything higher if there would be anything higher than 6.60. So let it as it is, my best guess is that if you try to much you'll end with a clean and sober BRICK.
