Identify Original and AP Set
- take out the phone case and battery.
- original set comes with authorized company sticker (Zitron, Avaxx, T-Choice, Midland...)
- AP set comes with AP company sticker (Final Choice...)
- press *#06# to check the phone 15 digit serial number (IMEI).
- compare it with the IMEI written on phone sticker (back of phone case) and package box sticker.
- for original set, these serial numbers are the same.

This is from the obsolete thread but also from what I understand last time. Though your explanation on the changing of box seem plausible too. Anyway I'm posting this from my red  nexus 5

it spy on my email... if the gmail u sync is the email u put to receive ur itinerary.. it will spy on it.. and tell u when its abt 2-3 days be4 ur flight...
but u also need to enable in ur google now setting la...

To go into bootloader mode, no need adb also can. Just turn off the phone and hold Power + Vol Up and Down (I think is up + down else try with power + down or power + up)

thing is, how to get OTA when we'r using custom recovery already? 

Best ROM so far?

Is the S2W function drain battery? Mine drop about 5% for 2 hours idle... is that normal?

Guys wanna ask if it is ok if i pull out imei sticker at the back?

Hey all. Newbie here
just wondering is it worth it to upgrade from Nexus 4 to N5.
still loving the N4 just a bit dissapointed with the battery life.
wondering if the N5 is much better or so so only?
