We need those phone shops that actually can hack your phones back, just like when we use custom OS in nokia phones pre-smartphones, normalize custom ROM again.

Heads up that you should still be able to sideload over ADB (the origin of the term on android, after all) without the wait, so setting up a new device before the 24 hours are up is still doable.

How does that affect you more than once? Isn't this just after initial setup?
