What is the current easiest method to unroot a D1 running BBv0.5 (FRG22d). I know this has been asked many times and I've read some of the tutorials but I'm confused as to what is most current. Obviously I would prefer to avoid RSD if possible. I was under the impression that accepting an OTA update would break root, but Clockwork is not allowing the OTA update. Will flashing Sprecovery or an older version of clockwork allow the update to break root? I'm giving my D1 to my wife and want it unrooted so she doesn't accidentally break it. Thanks.
