Root Rooting, warranty, and restoring

[Sailing_Nut]

Hi all!

Just wondering if one can restore from root in a way that it is undetectable and therefore if it was returned, no warranty issues.

If the answer is yes, can the restore be accomplished if for instance, the screen was dead?

Trying to decide if I want to root immediately when I get it.

TIA!

Unrooting and relocking is a pretty simple procedure. If the screen is dead, however will be nearly impossible.

Actually, it should be pretty easy and there's no reason you'd need the screen on.

You can boot into Fastboot mode without having the screen visible; power off, then power up while holding the volume keys.

You can then use the ADB fastboot utility. Do "fastboot devices" to make sure your device is visible. Then "fastboot oem lock" to lock the device's bootloader.

To make sure it was wiped, I'd probably do "fastboot oem unlock" again to wipe it, then a "fastboot oem lock" again to finally re-lock it.
