I just received my second replacement GNex (first one had screen issues) and when I went to boot it up for the first time right out of the box I noticed the Un-Lock symbol at the bottom of the initial Google boot screen. At first I wasn't really sure but then I booted into recovery and looked at the Loader State which confirmed that it was unlocked. I don't mind this as I was planning on unlocking and rooting anyways as was my original GNex but I was wondering if there are any checks I can do to ensure that the phone I received in an already unlocked state will be good for the long haul? My biggest concern is someone had the thing overclocked too high or something. I did a pixel checker to make sure the display is all good, did a root checker but it is not rooted. Anything else to check? I have 4 more days until I have to turn in my original GNex so need to make my decision soon. I plan on rooting and flashing a new rom onto the CLNR GNex soon to make sure that goes alright but otherwise not sure what to check. Thanks in advance for any comments or suggestions.
