could somebody direct me in the correct place to find out how to do this?

Second post in the first result

I don't know how to upgrade it and the second link is not helping me........

What does the calculator say on the front of it? There's two different hardware versions - one says "USB Power Graphic" and the other says "USB Power Graphic 2". I'm pretty sure the process is about the same with both, but I've only done it with the older one.

This has a number of links and is worth reading through.
Specifically this pdf. Unfortunately there isn't an English translation that I'm aware of, but you can copy/paste the text into google translate or similar and it should work fine.

Anyway, I forget how to see which one you have, but Spyro had an SH4 one with "Power Graphic" on it, you may want to ask him how he found out that it wasn't an older one.

I don't quite remember exactly what I did, but I found something I wrote some time ago:

I had this same problem. When you get that error message, press the F2, AC/on, 4, and RESTART (on the back) buttons. Then release them. Next, press and release the 9 key, and press and release the x key (multiply key). Then try recovering the flash. Also, your calculator could be the new model (Power Graphic 2). Try recovering with the "2_02_0201_sh4.fls" file.
