How to use this Extra_ Area files?

These are just service mode keys, hidden by Sony in the syscon firmware. They are implanted in the latest version of pysweeper and now all models can enter service mode.

My 07g was not fixed properly. Have you tried to fix 07g?

What do you mean by: fixed properly? Could you elaborate pls? Because if you're asking whether I've been able to unbrick 07g, yes many times.

I got a Pandora's Battery, and I made jigkick620 memory card. I used it to unbrick both 04g and 09g successfully, but 07g was not successful. I put it into the 07g and the screen didn't light up, but the LED indicator light looked like it was writing normal data，I waited for a long time to make it look like the writing was complete, but then when I tried to power on 07g normally, the screen still didn't light up, so it was not successful.

I believe that particular 07g motherboard you used must have had a hardware issue of some sorts as I never had an issue with 07g. @Davee's working on a universal jigkick supported by all models, that I thought would've come out by now, Christmas but I suppose it'll be done by new year's or down the line. I hope it'll be possible soon so keep an eye out. And I hope his release will get the job done for you as well.

Have you not encountered any screen issues with Pandora's Battery and jigkick620 unbrick 07g? Isn't this post also mentioning that the 07g screen won't work?And who is Davee?

No, never.
Yes. That's right.
The creator of Infinity and many more...
And just wait for its release.
