for people too lazy to read, here are the (really dumb) steps to be allowed to install unverified apps again:
```
1. Delve into System Settings, find About Phone
2. Tap the build number seven times to enable Developer Mode
3. Dismiss scare screens about coercion
4. Enter your PIN
5. Restart the device
6. Wait 24 hours (MANDITORY)
7. Come back, dismiss more scare screens
8. Pick "allow temporarily" (7 days) or "allow indefinitely"
9. Confirm, again, that you understand "the risks"
```
