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 whatever reason you're tired of flashuit custom ROMs and want to return to stock Android ROM that came preinstalled on your device Nexus, we see in today's video tutorial how we do it. Another reason why you need to install the stock rom is when you want to send the gadget to be repaired under warranty. Be aware that if you root at the gadget, it will not be covered by warranty. So, before being sent under warranty, you should return it to the factory settings. If you root and unlocked bootloader is a simple "Reset configuration Gabrica" ​​what is in the operating system settings in the "Create a backup and reset" will not be helpful!
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)
- Stock image archive will contain the official Android operating system for your device which can be downloaded from the official website
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.

  1. Hello!
    Can I put the stock rom from google using custom recovery?

    • Adrian Gudus said

      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

  2. IOS why not make tutorials? only android and android.

  3. 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 moves excellent, flawless well, did not miss anything in stock ROM, compared to one custom that is "bald" and go only bugs at every step.

  4. 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.

    • Adrian Gudus said

      It is not enough to put the 3 "packages" so simply in an archive. You packing your in a certain way and then the resulting archive should be signed.
      If you look the more patience you will probably find a rom stock (odexed or deodexed - can you clarify a tutorial future means odexed and deodexed, advantages and disadvantages, do not hesitate to ask that the comments box. The more applications, the will have a higher priority for a future tutorial) you can flash custom look of 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.

  10. Well May meseriasu ', then do not run ADB and fastboot! ADB is created and is used to "push" the files to a device from a PC, Mac, etc..! fastboot, in contrast, is a set of commands for performing operations change system files.

    PS - I made a little cabbage ...

    • Adrian Gudus said

      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.

      • Inattention in the current technological context, could be corrected by re-record / edit video before being posted on the site ...

        PS - I know very well that the terms in domain are such operations since the appearance of the first Android.

          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?

            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.

    I have a tablet block model method and a kid who does not know the model applied. There are possibly reset method?
    Mention is a tablet DICREA TAB720.

    • Adrian Gudus said

      Every device has a recovery mode that can be accessed through a combination of buttons. Now this combination of buttons varies from device to device and from manufacturer to manufacturer.
      From that you can reset the tablet recovery mode but you will lose everything on it (downloaded applications, files, accounts added)
      If you enter the wrong pattern too many times, you will be asked at some point google account and password, so you can gain access.
      I do not know to tell you which combination of keys to recovery mode because today I first heard about this tablet from some research I see that it's very popular and information about this tablet are very vague.

    • Adrian Gudus said

      Search our tutorials using the search box in the top right. "Install flash player on jelly bean" or "install flash player on kitkat" depending on the version of Android you have. Most likely you have Jelly Bean

      • I do not think you can install flash player on a Smart TV to see the content of the site, so make better and climb tutorials on YouTube to see the whole world from anywhere with any device.

      • Dr. madalin said

        Hi, sorry to respond after a long time, yes I had no time. Well I 4.4.2 on it, I once tried to make them root and we did. Now I want to make them update and will not let me, I see a red triangle on it when I try to make them update. I can do?

        • Everything you did not say what version of HTC One, M7 (variant of 2013) or M8 (variant of 2014)? I think that if you tried to root Yorkers probably have unlocked bootloader and therefore you can not update because everything has to be stock.
          As I said the first time on XDA or Google search "HTC One M7 / M8 (depending on your version) back to stock rom"
          If you just unlocked the bootloader you can lock into place giving the command "fastboot oem lock" the ADB phone is connected to the PC via USB and is in fastboot. View as Christ did recently a flash tutorial on how UIM factory image on Nexus Android 5.0 4 which showed how unlocks and locks the bootloader. You can look at it to get an idea.
          I do not know what method you used to root the phone, if the bootloader is unlocked or not. What I wrote above are just assumptions. HTC One that I can help you more. Any action flash, root Risks that I think you already know. I or Videotutorial team are not responsible for any problems that may occur during the aforementioned actions.
