Since EZ-RC has closed down, JP1 is your only option to get these remotes upgrades. We will (eventually) support all remotes formerly supported by EZ-RC, including the Moster Revolution 200.
I know in the past you used to have some connections at UEI. Wonder if they'd go for a "we'd like to redirect ez-rc.com to hifi-remote.com, talk about the support for the remote from our open-source tools but we need a way to do the firmware upgrades. Can you give us that info and we'll take over the self-support for people who have the remotes"
They might find that's a good way to go instead of dropping the customers entirely.
As some other users, I just got a C2 from one of the chinese sites, the ez-rc.com site, even though still up no longer has the option to register new users (05/14/2017) . Any workarounds on how to upgrade the firmware?
Even though I got the email from ofa about they would stop the ez-rc.com site, I confirm I can still update firmware to my c2 that I ordered off ebay.
I was ready to live with an older firmware, but I decided to give it a try to update the firmware on the site anyway. Luckily it went through.
