how about if i were to hose my note 8 and need to recover to complete stock. is there anything out yet for the US WIFI version? just wondering as i might wait untill i root, install recovery etc...
Now the only way you can hose your stock firmware is to mess up a flash, or purposefully delete system files in the root.
With that said, you can safely root with Saferoot.zip. It does not flash our change your counter. So a OTA or Kies update will work as if you never touched the device.
Now that you have rooted safely, you can install Xposed framework and it's modules... they will not hose your device as they are boot only system options.
I recommend Ti backup pro, and Solid Explorer but be careful about doing anything in root, as their may be irreparable consequences without a proper ROM.
Now for recovery with a replacement ROM. There will be a new ROM release soon, so when it does come out, it will be available to download. That will be your best option to recover if needed. Note... The only way you will hose a device is through a bad flash. So I would stay away from flashing any custom bootloaders, recoverys, kernels or ROM. Until you read up and are well educated on proper flashing techniques. All I can say is stick with developers threads on the specific model and have given plenty of info on the subject. Never blindly take chances.
As for recovery after saferoot.zip... as long as you never flash afterwards, you will never need triangle away, which is a plus... all you need to do is do a factory restore. Yep, no need to run any un-rooting tools, though you can use Supersu's clean up for reinstall and reboot if you want before doing the factory reset.
I know, I have done plenty of testing with custom and factory ROMs. I have personally found no need for customized bootloaders or roms, once I have found where and what to tweak. What little benefit from the customized options that are available, were too little for the trouble involved.
