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.

  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, 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 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" 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. 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.

  5. Hello I would like to ask how you say bitcoinu has made a cv results

  6. 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, confuse them. I'm Adrian. Adrian tutorial is conducted as written and as its title and the first comment above

  7. 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've 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,

  9. @ Moldoveanu

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

  10. 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… 😉

    • 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 have been corrected by re-recording / editing the video before it was posted on the site…

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

        • Adrian Gudus said

          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.

    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.

    • Well, I can't even see… that the guys from VT.ro don't upload the tutorials on YouTube to work on any mobile device / tablet / smart TV. We have to put new flash to see, no IT&C site uses JW Player, only the most popular YouTube with which you can see any clip on any device be it tablet / phone / smart tv. Cristi solves the problem and removes that Jw Player that is useless, uploads everything to YouTube so that everyone can see it on any device. You only see it on a PC with Jw player on your phone / tablet / smart TV, not so much

    • Adrian Gudus said

      Search our tutorials using the search box on 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.

    Cam tutorials thin lately.

  22. I greet you. First of all, appreciation for the work you do in showing us step by step, and in a popular language, each solution of a problem, or how to deal with some programs on your own. : for two days, avast has been warning me that it blocks "a dangerous site or a file", no matter what web page I access (even from you: D), forget the address written by avast: "Infection Blocked
    URL: 'http://……/shopping/ppapp.js'
    Infection: URL:Mal" - I reinstalled avast, I tried with tdsskiller...is it a stronger virus? the night before I installed 2 programs after watching some tutorials made by you (but I don't want to say that they are the problem. .far from me this thought:)>-), they are: antilogger free and malwarebytes anti-malware (I also uninstalled them). would avast have upset them?:D, I use mozzila, but I also tried with google chrome, the same... and the second problem dates back to last year, immediately after installing a w8.1 (but in an unorthodox way, if I can say so). it appears that windows is not activated, it asks me to enter settings, but it doesn't show me how many days I have left, after which I can activate it. The installation took place in the middle of December. Besides, the PC works fine with this w8.1, only the web camera doesn't I know what it is that gives me an error when I want to open it. maybe I shouldn't reinstall windows, because I don't really know how to find someone with these trojans...:)) just snowed in probably:d. that's it for now, I don't want to take up too much of your time, thank you for reading my message and I'm waiting for an answer (maybe it will be a helpful one) I greeted you :)>-

    • You are searching for “HTC One M7 / M8” (back to stock)

      • 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 told you and the first time search on XDA or Google "HTC One M7 / M8 (depending on your version) back to stock rom"
          If you only unlocked the bootloader you can lock it again by giving the command "fastboot oem lock" through ADB the phone being connected to the PC via USB and being in fastboot. You can see that Cristi recently did a tutorial on how to flash the factory image of Android 5.0 on the Nexus 4 where he showed how to unlock and lock the bootloader. You can look at it to get an idea.
          Careful!
          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.
