any luck with anything?
Yes, at last. The necessary adjustments in the OS 2.00(GII) image are:
at 0001001C: 02 to 80
at 0001001E: 00 to 5D
at 0001001F: 00 to 7C
at 0003CCBC: 8B to 00
at 0003CCBD: 0A to 09
at 0003CCC4: 8B to 00
at 0003CCC5: 06 to 09
at 0024FFFB: 7F to C2
A FX9860G SD running with OS 2.00(GII) doesn't show any side effects, yet.
Though, don't take the absence of side effects for granted!
Of course, you work on your own risk. At any rate ensure that you use the right base image. The bytes at 0024FFF8 must be 10 02 1D.
Verify a changed image before using it! A binary filecompare must yield the pattern as stated above (including the original bytes!). If there is any difference: cancel! If you have any doubts: cancel!
Here's what to do...
1a) Get this file if you don't want to do it yourself http://www.megaupload.com/?d=NDLQQ8FL and skip to step 4
1b) Get this File
http://www.megaupload.com/?d=8ABHVADN - Thanks nexgen for this @ http://www.casiocalc.org/index.php?showtop...ost&p=47291
2) Extract it and open up FLASHG2_2.00.FLS with your favorite hex editor.
3) Strip it down to 2555904bits (that's BITS) (in hex that would be upto and including address 26FFF0F)
then do the changes stated:
at 0001001C: 02 to 80
at 0001001E: 00 to 5D
at 0001001F: 00 to 7C
at 0003CCBC: 8B to 00
at 0003CCBD: 0A to 09
at 0003CCC4: 8B to 00
at 0003CCC5: 06 to 09
at 0024FFFB: 7F to C2
4) Save this as UpdateCode.bin somewhere where you can find it.
5) Download extract and run the OS update exe from 9860_osup_200.zip (https://edu.casio.com/download_service/down...orm.php?fn=1085) DO NOT CONNECT YOUR CALCULATOR UP.
6) Take off the battery cover of your calculator and SHORT OUT the two contacts which are in a hole TO THE RIGHT of the P button.
(I used my calc-calc connector cable for this
This should invoke a program called "OSUpdate" and it should be displayed on the screen.
7) Once an alert comes up saying "Connect your calculator" go to C:\Documents and Settings\USERNAME\Local Settings\Temp\{xxxxx-xxxxx-xxxx-xxxx-xxxx} [you'll have to do a bit of looking for the folder that contains UpdateCode.bin
8) Once you have found that folder REPLACE UpdateCode.bin with the modified one in part 4)
9) Go back to the update program, CONNECT your calculator to the computer using a standard USB-A<->USB-B cable and click ok on the dialogue boxes.
10) Wait
11) Once the update is complete, for some reason, it says "Continue with update".. Just click cancel.
12) Enjoy your "updated" 9860G/G-SD
Thanks for all your work guys!
Poly solver solves them in surd form too.
