In that version the screen has to be turned on to make a change.

The cheapest way to do this is lock-screen notifications - the passcode unlock is a bad hack if that fails.

It's not easy and the way I'm trying to do it requires a usb drive which I had for about a year and then lost it. Haven't gotten one yet since a year but I will for this!

Yeah when I get time I'm going to check all the files I have.

For some reason I have an extra folder called "sideload_files" with about 10-12 files in that, some are .js. I'm wondering if this folder is needed at all; going by people's reaction to other uploads it doesn't seem so.

Alright, have a look at the pinned ios post and get familiar with the clean download so you can see what's different when you get mine. Then feel free to modify it so that it matches the original and send it back! I'll do this tomorrow. It's time for me to sleep now.

+1 This is great. It was the only reason for me to jailbreak and now i don't have to. Thank you!

Hey @MikeJanik - I just restarted XCode and tried it again and was able to move past this issue. Then I started to get a security issue and the following answer helped me because I finally got the profile in General > Settings.

Solved by updating the iOS to 9.2 beta 3.... just now

Thank you for the links, lorna. I'll check them out and hopefully have a better understanding of how f.lux works :)

@rkleim Hi, I imagine the F.lux_team are a little busy right now trying to clean out the 'black screen' issue so, having had a similar experience to you initially I though I may be able to help.

I have made up a couple of screen caps that may explain.

I am assuming that you have successfully loaded the “iflux.xcodeproj” project in Xcode. The next step relates to the 'XCode/Preferences...' menu item, that is the preferences for XCode not this particular project. Shortcut: ⌘ , You will see this screen:

Click on the 'Accounts' tab and enter your Apple (iCloud) ID.

Then go to the main XCode screen with the f.lux project loaded and in the centre make the adjustments indicated here:

Then with your iOS device connected, press ⌘R follow the bouncing ball.

I hope this helps. I'm sure I will be corrected if I have said anything incorrect.

Right now, we fire them anytime there's a "change" in our curve, but we can avoid doing this if you're not actively using the device (or more likely, make the threshold a lot higher).

Sometimes the transition curve is very steep - so we erred on the side of matching the desktop curve (i.e. too many notifications). But we can fix this and make it do fewer steps.

(On a jailbroken device, we just hook the screen-on/off and it's much easier.)

Get it in Cydia - the beta repo is empty for a while once we ship

We do not use substrate.
