Ok,

I'm about to get my GTA LCS unpached.

How do i downgrade this to 1.5 then up to 3.03oe-C ?

Is there a full tutorial on this? Could'nt find one.

There isn't a downgrader for 2.81 firmware. But there is one for 3.03.
you best bet would be to upgrade to 3.03 then use the ta-082 3.03 downgrader.
This will get you to 1.5, and there are plenty of tutorials for upgraging to 3.03 oe

As stated by zero you need to upgrade to 3.03 and use the downgrader

Dont worry about the TA-082 because the 3.03 downgrader supports that motherboard

Go google a tutorial on how to upgrade then downgrade

tut can be found here http://boardsus.playstation.com/playstatio...sage.id=2792391

yeah follow the tutorial to the letter or else you could end up with a brick

There is a tut included in the noobz d/grader.

the 3.03 downgrader is very good, i used it myself to turn my psp into a fun console to play
