Lighten up: Fanjita talks of screen brightness issues

Fanjita of the Noobz team has responded to certain issues about the screen brightness after using the downgrader. He’s posted an article on their team’s blog that explains why this happens and what you can possibly do about it.

They’ve discovered that this issue seems to be isolated among the more recent PSP versions of the TA-082/A-086 batch – those that come with FW 2.71 or later. To explain further, here’s a direct quote from homebrew hero Fanjita:

This means that if you run a lower firmware than v2.71, then the display isn’t given the right brightness signals. Where normally you would see a bright screen, and it would go dark after a while of not pressing any keys, now it is normally dark, and goes bright if you don’t press anything for a couple of minutes.

The best fix is obviously to install a firmware that can control the display correctly. Fortunately the OE firmwares, e.g. 3.10 OE, will do this. The only drawback is that, when running homebrew in the 1.5 kernel mode, you will get the old screen behaviour. But you should be able to work around this by pressing the ‘screen’ button a few times.

While that in itself can be a bit technically highfalutin for some of the newbies, Fanjita actually gives a suggestion for the more advanced users. You can actually create some hybrid firmware “that will use the later screenhandling code in the 1.50 kernel mode of OE.”

Sorry if all the jargon might be a bit too much, and that’s why we had to post some direct quotes so as not to leave room for error during lost-in-translation moments.
