I've posted a thread titled "[Q] Help Restoring S-on And Unrooting" but looks like that's going no where. My phone is still currently rooted and S-off, I flashed a froyo based stock rom 3.70.651.1 and the phone recognizes the 4.24.651.1 OTA update. If I accept the update will the phone return to S-on and unrooted?
Most likely you won't be able to take the update with a custom recovery in place. Having said that, if you were able to update, you'd lose root but you would keep S-off. You're better off flashing a stock rooted ROM.
