Check the version of your calc. The version is marked on the back of the calc. You can see a letter in a small circle which is at the top-right corner of the rectangle that has text in it. If the letter is A, you are lucky. Just open the calc, find the P4 jumper on board, fill the gap with pencil. Then turn on your calc, see if there are 8 modes available.
If the letter is B, see the following, it is difficult to upgrade, but it is possible. CAUTION: The success rate seems be VERY low. About only 20% can do it without experience. It is easier to do it with a magnifier. It will mostly affect the display(too dim, strengthen ) if you fail. Or just not able to turn on.
Adobe acrobat 6.0 professional free download filehippo. TRY THIS AT YOUR OWN RISK. I'm one of the administrators from Fx-ES(MS) calculator forum. This guide is only for Ver.B ROM 18 ES Series. This is called hardware upgrade(maybe hardware modify? Google play services apk download for android 4.0.4. I'm not sure.) in our forum and '硬改' in Chinese. The ES series are easily divided into 82ES, 991ES and other models by a jumper.
This jumper were easy to modify in the past few years. (Can you see C(Canceled?)P0, CP1, CP2 and other contacts on the PCB of your ES(Ver.B)? They were connected with the CPU in Ver.A. You could change the P-value(P means program) in the self-check screen by connecting these unconnected contacts.) If you have a Ver.A 82ES and it's ROM 18, you can upgrade it in an easier way with no danger. ROM 21 ES calculators have no 991ES programs inside. So it's impossible to upgrade ROM21 calculators (software/hardware).
