Yes. The firmware referenced*, and being run here is European, as was my original FW. I just renamed all the satellites and put in the correct geo orbit locations. *this is S10 firmware that will also operate in an S9.
If you already have satellites/channels scanned in. You can export your channel list - Dump by USB>Misc files>TP_Prog - to a usb stick. Load the new firmware, then load your TP_Prog, and all your channels are back. This should work with just about all updates, I have heard there are a few versions that didn't work, but seems rare.
This will also be required, changing the video from PAL to NTSC. Copy and print out.
