Please need help with fx-9750GII

Hi everyone:

I make this post because I need help for my calc fx-9750GII.
Last a two days, I made and upgrade of OS from fx-9750GII to fx-9860GII
It works perfectly.

The problem is if I want to downgrade to the previous version (factory default) how can I do that, because I don't have a copy of the default OS (which is OS 2.02.0701)

Please, if anyone have this version on your calculators, can you send it to me to my email brleoal@gmail.com , I will appreciate this favor.

Thanks

Can you please send me a copy of the flash file you used to upgrade your fx-9750GII to fx-9860GII (OS 2.02.0701) for I have been searching for a long time with no luck. Thank you for the reply,
