Good to know right there. I got my I1 recently. The Go screen says 1.9.1.30+, Cam 1.9.1.10 and RC 1.6.0.
You'll want to stick with 1.6 on the controller.
Is there a DL for 1.8.xx?
Yes. In an exhaustive search, I stumbled upon this little gem.

I recommend downloading and archiving everything, as lord knows when this page is going to go away.
I haven't ever done FW on the I1, just on P3's and I stopped prior to them locking the system (see sig), whats the rollback process?
Install the .bin file on your SD card, install the card in the camera, turn on the Inspire, and watch it go. The camera should make a noise kind of like a quiet version of the old floppy drives when they accessed files. If not, then something is going wrong.
You're SUPPOSED to get feedback from the bird via the LED lights, but I have found that to be unreliable. So here's what you do:
1) Set a timer for 20 minutes.
2) After 20 minutes, shut the bird down and pull the MicroSD card.
3) Insert the MicroSD card into your computer and read the log file. The log file is pretty self explanatory. If it says, "Success," you're done.
Assuming you succeed, REMOVE THE BIN FILE FROM THE CARD, or the update will start all over again. Remove the log file, too. You should be done.
If the update fails, you *might* have to update to an earlier version of 1.09.xx first, and THEN update to v1.08.xx. It's in the release notes that you can only downgrade one FW at a time.
Lemme know how it works out.
