I'm picking up my Note 3 on Tuesday. Gonna stay on the stock firmware out of the box, no OTAs will be allowed. Gonna root with Kingo. I dont wanna mess with recoveries or anything other than disabling software update to prevent kitkat from being pushed. I realize it could be an advantage however as I could then in the future use the 4.4.2 update as a type of recovery image, if I need to send it in for service or sell it. I know about sammobile and all other "offical" stock tars floating around but they arent really from Samsung. They dont even release recovery images for the dev edition! Kingo wont trip knox and I wont be modifying any system apps (I may even opt with using a permission denying app to block SDM from having network access, instead of freezing it, as it's less aggressive). I will make an ADB backup pre-root and restore it before updating as well.
If the time comes I could use Kingo or Superuser to unroot, wanam to fake the status as offical, adb restore and have the samsung experience store guys flash kitkat or use the OTA which, assuredly, would remove any and all traces of root. Sounds divine.
So will the update process, whether from the Samsung guys or OTA brick my phone if I do it? I should have everything removed by doing it this way. I don't like the idea of messing with all these different recovery tars as they arent 100% official. Just wanna make sure the Sammy update wont brick it, because it knows, somehow.
