Hello,
Unfortunately, if you have factory reset your pedal without backing it up first, there is no way to recall what was deleted.
I’m not sure what the original issue you described was. The recommended steps for a new firmware and H90 Control release is to first install the latest version of the app and then use the app to update the pedal firmware. If you have update issues, there are alternative methods that we can suggest if you contact support. A factory reset should not be done if you are having update issues.
You can backup your pedal using H90 Control, see #1 on the list: https://cdn.eventideaudio.com/manuals/h90/1.10.7/content/h90-control/edit.html#parameters-edit-menu
Sorry, I wish a had a better solution for you. Our staff is quick to respond to forum posts and support tickets so it is best to be patient and wait for advice in situations like these rather than resorting to a factory reset.
