I thought the device will go for a reboot after OTA installation is complete, instead of letting us do a shutdown and go into recovery. Was I wrong?
Oh you're thinking of taking the OTA by letting it push and install by itself? I hope you're on 232 or lower and plan on fxz'ing back to 905 if that's your plan. The OTA wipes the cache itself in the same order I recommend. Those on 235+ will never have to worry about "taking the OTA" cause it's not ever going to happen.
