When we buy a phone, by default, it comes with the locked bootloader and an official recovery preventing to install packages that are not signed by the manufacturer as a security measure. However, the Android ecosystem is a much more open ecosystem that, for example, iOS, so, although this is the default setting, with a few simple steps it is possible to unlock the bootloader and take complete control over the device, and may, for example, make root or install other versions of Android.
Nexus is the range of smartphones developed and maintained by Google, predecessors to the current Pixel range. Just like any other device, these smartphones come with the locked bootloader and an own recovery that prevents modifying the system, however, can also be changed easily. The problem is that, once modified, if we want to return to factory settings, for example, to continue receiving official update or process a warranty, manual, process step by step, can be rather complicated and not always leave the phone with the standard configuration.
By this, if need make us of that our smartphone Nexus (or, even, Pixel) is with its configuration original of factory, then, you leave a complete guide, step by step, with which you teach to install the last version official of Android and, also, to restore them values of factory of any of these smartphones.
Up to what point is worth the change the Nexus factory settings?
Although the brand “Nexus” has lost its essence (a smartphone of high benefits by a module price and especially thought for developers) since the launch of the Nexus 5, have a phone developed and maintained directly by Google has many advantages, for example, be them first in receive, via OTA, them updates of Android and them patches of security.
There is nothing better than a pure with real-time updates Android, therefore changing ROM, although there are alternative, really not worth it. Similarly, today the root is not practically necessary except for very specific configurations (and less), so, unlock the bootloader and change the recovery only for this gives us more than what we earn that, mainly, we are left without the official update from Google to lose.
However, no phone has infinite support and either a Samsung, an LG, a Pixel or a Nexus, sooner or later will be abandoned and without support. Starting from this moment, can be a good idea proceed with the release of the bootloader, install a recovery and install a rom custom as CyanogenMod that us allow follow taking advantage of all the potential of our smartphone, at least, during several versions more.
However, while have support, the truth is that modify these aspects is something totally unnecessary and has more disadvantages that the benefits that brings.
