How to reinstall the official rom on Android phones - video tutorial

Hi friends, this video tutorial will show you how to reinstall (ROM) telefonele original OS mobile operating system Android. We do this by means of a backup that I made earlier.
Restoration will be done from ClockworkMod Recovery, how to make a backup for Android phones is in the tutorial " Install CyanogenMod, the best rom for Android phones and tablets "If you are in a hurry and do not want to watch the whole tutorial you can jump directly to the minute 9:20, there is how to back up on Android before installing an after market rom or a special kernel, the original Android version is very important, especially when you take your phone to the service.
Whether you're tired of all kinds of experiences with ROMs, or you have to take your phone to service, should always have a backup ready made official ROM in a few minutes the phone can return to the original and all bugs custom ROM or kernel may disappear.
Service official sites do not want to hear the root, custom rom, overclock kernel and stuff like that, without the original operating system will not be able to receive free support even if your phone is still in warranty period.
Restore process is super simple, go into recovery (ClockworkMod revovery) and we go on "backup and restore", here we have two possibilities, either restore a backup from the card or from the internal memory, depending on where you put the backup. After restoring the official Android we will have everything in place, the Android operating system will show exactly that at the time of backup with accounts, applications, passwords, the original recovery will take the place clockworkmod recovery and thus we will erase all traces "Software adventure".

  • The Nexus 7 I did root the Nexus Root Toolkit v1.5.4 she was Jelly 4.1.2. Subsequently official appeared and Jelly 4.2 Store Play me off and go crazy about Chrome and Firefox. I 4.1.2 Backup with empty (but not ClockworkMod). What can I do?

    Give a restore and return to the initial state. 7 Nexus tablet is a very good, do not see why anything should change it. Android experience is pure, clean, unadulterated.
    Root is not a must, can be done only in special cases when we simply did not do.
    For your problem you can try to empty the cache's Play Store. Settings / Aplications / Google Play Store / Force Stop, Delete Data, Delete Cache.

    • Hey I got a mini s4 and I rooted it with kingooroot and after some time I found that I can not update the software. I accepted the situation and I uninstalled root.dupa a while and I wanted to do when I enter root and boot menu appears to me that picture when I rooted it what to do?

  • And yet ... when you root the original system and then install cwm recovery and with the latter you can make a backup ... (because the phone from the factory does not come with the possibility to make a backup), restore the original rom don't unroot! Not? To unroot and remove cwm recovery do not use a PC and certain utilities?
    I mean just restoring the original rom I consider that the device is not "like new" as long as root and cwm recovery remain ...?!?!

  • Catalin.81-Rm.S:
    And yet ... when you root the original system later to install CWM recovery and the latter can do backup ... (for the factory phone does not come with the possibility to make backups), restore the original rom and unroot do not ! No? Pt unroot and remove CWM recovery using a PC and do not have certain tools?
    That only consider restoring the original ROM that the device is not "like new" as long as you remain root and CWM recovery ...?!

    Wrong, restoring the original ROM lose CWM and root.

    • OK! I do not deny your skill but gave no answer enlightened me and probably many are confused and somewhat autocontrazici you (I mean the other tutorials).
      I followed with great interest the tutorials about android and root and I want to thank you and specify on this occasion that I managed to root for an LG P690 by the method with ADB described in the tutorial "How to root an LG Optimus One P500 with Android Gingerbread 2.3 "
      Also thank for the tutorial DarkTremor P690 works perfectly but not in original ROM but only CM7 (do not know why but it does not matter).
      From what I understood I simply videotutorial following restoration of a backup made with CWM does not remove the root and root for you no ROM (software) it is elsewhere.
      Cristi The method described here is more simple than that described in the tutorial you probably KDZ but LG does not apply for another explanation that can not find.
      Cristi says something of a recovery here came from the factory and has access to what I do not know LG.
      LG (both a and a Optimus NET Optinus Black x2) key combination Volume Down + Home + Power does not go in any recovery menu but do factory restore. Probably the method described here is valid for the case of Notes not. P500 (for ex.) Otherwise not see the point tutorial with KDZ which is more complicated and involves a PC.
      To me (at least) a P690 restore backup made previously with CWM and restored everything with CWM not remove root (checked with Root Checker and other applications that require root) and no CWM. So I again original ROM but just doing this device is not ready for the watchful eye of those in service .. :))
      If I'm really wrong, maybe you'll tell me WHERE I'm wrong ...?!?
      Maybe they and other visitors to know.

      Thank you!

      • I give a simple example ...
        If you delete an operating system on a computer, for example a Linux and put back a windows, the one that was from the store, is there anything left of what it was ????
        Everything was gone and we only see what we reinstalled ...
        It's a bit similar to the Android operating system, which comes from the open platform, Linux ...

        • Hello Cristi I have a neo degree, and a 2 asus zonfone I did not manage to do any. Room root and so on.

  • Hi Cristi, Tell me please is there a way to backup the current ROM without doing a previously root Samsung Galaxy S2?

  • who wants to install jelly bean for samsung galaxy s2, can find it on sammobile.com ... it's the beta version. I installed it and I can say that it works better than ICS, without errors.

  • Hi I have a P6 Allview Stony and I would like if you can tell me how I can see the TV pictures from the phone. Specifically how it connects, if possible to a TV. Thank you.
