Return to stock Android, unroot, lock the bootloader for any Nexus

Hi friends, today's tutorial we will talk about a return to stock (back to stock) for any gadget range Nexus (Nexus S, Samsung Galaxy Nexus, Nexus 4, 7 Nexus, Nexus and Nexus 10 5)
If for various reasons you are tired of flashing custom roms and you want to return to the stock Android rom that came pre-installed on your Nexus device, we will see in today's video tutorial how to do this. Another reason why you will need to install the stock rom is when you want to send the gadget under warranty for repair. You should know that if you have rooted the gadget, it will no longer be covered by the warranty. So, before it is sent under warranty, you will need to return it to the factory settings. If you have root and the bootloader is unlocked, a simple "Reset settings from the tab" which is in the operating system settings in the "Create a backup and reset" section will not be useful!
To put into practice the flash rom-uire of his stock, we need the following:
- ADB installer (If you watched the last tutorial we introduced How to install Android on the Samsung Galaxy Nexus KitKat 4.4.2 and you still have the necessary drivers installed, ADB and Fastboot, no longer need to install ADB Installer)
- the archive that will contain the official stock image of the Android operating system for your device that can be downloaded from the official website https://developers.google.com/android/nexus/images
Before you plunge recommend uninstalling or disabling security software installed (antivirus). When you need to connect the device to your computer or laptop data cable that came with it, do not use USB hubs or extension cords and do not connect the gadget into the USB ports front (located in front of computer / front panel). Direct use of the motherboard USB ports located at the back of the computer.
You should know that this process will be lost through applications downloaded from Play Store, existing photos, videos and documents Declares pending. Before you take steps to return the stock, connect the device to your computer and save important files in a folder or a partition. Also through this process it will lose the root, custom recovery (if you have ClockworkMod Recovery or TWRP flashuit-Team Win Recovery Project) and custom ROM that you have flash-watching at the moment.
You can use the method outlined in the tutorial and flash-ui an older version of Android if you do not like or are not satisfied with the latest version of Android that your gadget automatically updated Nexus.

    • You can not do that.
      If you were less attentive, I extracted the archive after downloading, radio, bootloader and operating system image are separated. Not all in one archive as it happens to custom ROMs

  • I see increasingly mobile phone manufacturers like Samsung, LG, Sony, do OS Jelly Bean very fast, not only must use custom rom as the stock do the job very well optimized by producers so as to not have any lag, of abstinence, etc. If you use custom rom we will have the bugs as before, ie we will have a lower score than as the stock was I conclusion I drew it as rom the stock is best optimized, even if he in some processes has a small abstinence or less lag, this does not mean stuffing custom rom like going hard.
    I tested the LG G2, it moves excellently, impeccably well, it lacks nothing in the stock rom, compared to a custom one that is "bald" and only works in bugs at any step.

  • I saw.
    How I put in an archive?
    E really need them?
    I want to keep CWM recovery.
    I would not use fastboot for I have problems connecting your phone, PC is old.

    • It is not enough to put the 3 "packages" like that, simply in an archive. They must be packaged in a certain way and then the resulting archive must be signed.
      If you search more patiently you will probably find a stock rom (odexed or deodexed - maybe I will clarify in a future tutorial what odexed and deodexed mean, advantages and disadvantages, do not hesitate to ask this in the comments section. As much as possible applications, the higher the priority for a future tutorial) that can be flash-forgotten from custom recovery.
      Galaxy Nexus is no such thing, you find the XDA Developers forum but the problem is you do not get rid of the root, you'll still have your custom recovery and can not send the device in such warranty.
      If out of warranty and with the guarantee you're not interested, then it's ok.

  • Hello Cristi my opinion is that the state better with this samsung nexus believe that you have made your gift lau emag those in advertising are doing in their favor.

    • Inga inga, you confuse people. I am Adrian. the tutorial is made by Adrian as it is written under its title and above the first comment ;-) For your general culture, Galaxy Nexus is also made by Samsung, as well as Nexus S. Nexus 4 is made by LG as well as Nexus 5

  • Interestingly enough!
    I come up with a question: when do you do tutorials with and about Windows Phone? I also find this operating system quite interesting. So far you have only done about Android ...

  • Hello, please explain how the rum back to stock at tel. Huawei g300 after I put one at Vodafone Australia, the problem is that with this rum, I 3g internet function, and I'm going to phone warranty repair Thank you, wait a tutorial on this topic,

  • @ Moldoveanu

    Well tell you exactly what rom like to know if it comes to downgrade or anything that procedures differ.

  • Well, craftsman, don't run ADB and then fastboot! ADB is created and used to "push" files to a device on a PC, Mac, etc.! fastboot, on the other hand, is a set of commands for performing system file modification operations.

    PS - You kind of made cabbage ...;)

    • ADB stands for Android Debugging Bridge, a tool command line with which a developer can communicate and can make debugging (meaning your troubleshooting) an Android device, not just pushing as your handyman maria says.
      ADB can also be used to make a backup and in many other situations. ADB is used more when the system is up and runing (already booted and running)
      Fastboot is a diagnostic protocol amending and flashuirea system files using a USB connection between device and computer. Fastboot can only be used when the device is in bootloader mode.
      Vague about your argument considering that you are a craftsman
      Even craftsmen have sometimes moments of inattention, can not have a good day, can you stand the thought of others.

      • The inattention in the current technological context could have been corrected by re-recording / editing the video before it was posted on the site ...

        PS - I know very well the terms in the field because I have been doing such operations since the appearance of the first Android phones.

        • As you probably figured out (or not happen) people are attached to this wonderful site we also have a personal life, family, friends, some have a wife and child. Recovered a video tutorial about 1 time is not very pleasant! Do not replace a bit wrong it takes very little time.
          If all you're funny, do well and answer the comments below. By this will prove to others that you're a craftsman. Destructive criticism and reviews data banter with airs of superiority, we are good at all or just that you are craftsman?
          Marian Istrate's question seems very interesting, how about you put?

          • 1. I see you're no less ironic than me ...
            2. To the question of Mr. Istrate Marian: There are many solutions, including an application called "fotakill". But I do not understand why the update to prevent these updates from the manufacturer are not made for the sake of achieving them but they fix some errors and make some improvements.
