Cannot Re-enable developer settings after ROM re-install For.... Various reasons, I had to remove /system and replace it, I.e. fresh install my ROM. Now, however, I cannot do the build number trick to open developer options, and going through the dev tool menu states "Developer mode not available for you. You did enable it, right?". I doubt it is a kernel issue, since that copes fine, and the ROM is stable. I'm not gonna re-flash again today (Again, for various reasons). So, does anyone know how I can force it open?

Root methods will not work. Due to how the ROM is built, rooting and unrooting is done by flick of a switch... In the developers options.-NOW OUTDATED INFO, SEE EDITS BELOW

Root Works now! I managed to trip it on in SuperSU.
Some ROMs move settings around. For example, on Ressurection Remix a lot of options are moved to new entry "Customisation" in Settings. Check your Settings app.

You can also use ADB or Terminal Emulator and run following command (taken from there):

am start -n com.android.settings/.DevelopmentSettings


You can also check your ROM's forum thread to see if anyone else also had problems with enabling Developer Settings.
