Encryption android phone or tablet before sale

Hello friends, I know I can title may seem strange but I promise it is very fair. Before selling a phone or tablet, they need careful cleaning treatment, I do not mean the physical cleaning but cleaning the internal memory so that data can no longer be recovered.
From any phone can recover data even if they have been reset and apparently have no data.
Those who follow our site know very well that Deleted data can be recovered almost completely, especially if the fish is not rewritten memory. A cell is like any other storage medium, the data do not disappear completely deleted data that came in hand to others, surely we can do more harm.
The phone have private conversations, private photos, bank data, sms, data logging on different websites, forums or online stores passwords on facebook, twitter, google, yahoo and many-many more.
The safest cleaning method of the phone is its encryption before resetting to factory condition. In this tutorial you will see how to do this. Please pay attention to what was said in the tutorial. Under no circumstances should you interrupt the process.
For those who want to learn more Understanding encryption, we have some tutorials dedicated to this subject, which is now more topical than ever, in the context of interception of international communications.
AxCrypt, program, fast and very safe encryption of files or documents
Cryptophane, fast file encryption program
TrueCrypt, creation of encrypted containers for safekeeping data on hard or stick

  1. Pretty please, make a tutorial on what you need to know and be careful before buying a secound-hand phone with android or ios ... for example: as we realize that the iPhone is neverlock and what to look before I buy, and many other important issues .. (I really want to buy an iphone)
    I think it would be a pretty interesting tutorial for many of us ... (especially since Adrian si- took iphone, and promised to make a tutorial of this type ...).
    Thanks much and continued success!

  2. Cristi can you recommend a program to transfer data from PC to phone.
    I used Snapp but has many bugs.
    Can you help me please nice !!!

  3. Hello,
    After executing encryption, files added later (pictures, text files, etc.) will become encrypted by default, or can be recovered with specialized software, even after resetting the phone and bring it to its original configuration, the factory?

    • After activating encryption, all put in the phone and even the pictures that you make, will be encrypted.

  4. Cristi mamreferit a program for usb

    • Adrian Gudus said

      If you use the USB data cable that came with the phone, you do not need special software to transfer files from phone to PC and vice versa. Once you install the necessary drivers (which you can find on the official website of the manufacturer) when you connect your phone / tablet PC storing it (internal memory) and SD card (if there is one in your phone / tablet) will appear in My Computer . You'll be able to access the same way you access a USB stick that I connected to PC
      Each manufacturer offers a software suite that allows file management between PC and phone / tablet. Nokia PC Suite Nokia there for you LG PC Suite LG, Samsung of Samsung Kies

        If you want to not have ads in youtube android application, you can install XPosed Installer. Then go to this application on Youtube AdAway download and search there, and install.
        To activate it you must reboot the smartphone, giving 'attention on some devices causing Bootloop.

  9. Greetings

    I have a big request for you VideoTutorial team. Looking on at 22 and still have not found the time 03 see that there was, and here I searched but could not find what I'm looking for and even pay for such a tutorial at the moment and hope to click.

    So what this is about. I want to put another video soundtrack, and have the option to sync sound to video. If you caught the YouTube series made by Satan Cartoons ... For example, I made a video of some cartoon a few minutes and has the original sound, and I want to remove the original sound and come with new audio (but again, it can somehow synchronize with video).

    If you think you can do a tutorial on this, let me know, actually let me know and if you can, to know if you are digging on the net and tomorrow night.

    Thank you for your time spent reading this email and I hope you can help me.

    All the best,
    Iulian

    PS I tried to send it via the contact form, but does not send the message.

    • Camtasia Studio is a function of narration, upload video file while running talk microphone. It's perfect for translation and dubbing.
      But I think you know it, you can not sit an audio track over the video that if it is not perfectly synchronized.

  11. Hello Cristi,

    1. After you encrypt tel. and it reset / factory settings continues to encrypt and who is buying it? Remains affected buyer?
    Question maybe someone wants to buy, not necessarily to sell and know what they can expect!

    2. After you encrypt tel. can bring it back to the state they were before encryption?

    Thank you !

  12. Hi,
    I want to ask if reset to factory default reset is the equivalent of the hard site?
    if encrypted. decryption can take the option?
    thank you!

  13. HELLO Christ AM request if you can and want to give me AID: I bought a phone WIKO MARK FAST RAINBOW perfect functioning; A few months began to block; NOT restart stuck; WIKO ONLY be written, AM RESET AND FACTORY BUT WENT start block and tried again and NOT reset: Romania has not yet know that he's SANT MARKET MADE IN FRANCE: PLEASE VERY MUCH What do advise me ; What shall I do NOT work at all startup; It's something DONE TO SOFT or what is needful: IF YOU CAN PLEASE AJUTAMA: Many thanks:

    • Let me see if I understand. The phone is stuck at the boot logo (logo maker when starts) but after a while he returned and then you decided to make a return them to factory default. Now stuck and even if you leave it for a while does not start. In this case you can try to go into recovery using the key combination specify your phone model (Samsung for example is Volume up + home + power. It differs from model to model, but in general it is. A find on google combination) and facory there hitting the reset.

      • Hello Cristi.Multumesc more. I did what you told me and all I got stuck at least in System Recovery and made just after a video posted by the factory in their website and give odd headache, which can only be remove it and orient me to something else, too bad: One last question you advise me to do? in System recovery has so: System reboot now = Apply update from ADB = Apply Apply update from sdcard = System from Cache = wipe data / factory reset wipe cache partition = = = restore user data backup user data .. These ditch and remains blocked. Have a nice day Regards.

        • In recovery we select wipe data / factory reset (Clear data / factory reset your phone in Romanian) to make a return to factory settings. Then reboot system now going BE (now the system reboots) to restart the phone.

    Hello. I have a Samsung S2 Plus (I9105P) you have encrypted. Then after a few hours and restart stalled. I went into recovery, I gave factory reset and now it asks password when starts, I put the one we set it, and I say that's wrong. What could I do? What do you recommend? PS I have insurance and warranty if you need to get him in service or change it. Thank you very much.

    Hello, please beautifully I encrypted the phone and forgot the code I gave resetting from the buttons But still the code appears You can help me

    • Adrian Gudus said

      You can not do anything anymore. The only solution is to format it, give it a factory reset and lose everything.
      Next time, stop playing security features if you can not remember your passwords or password set.

  21. Hello be nice if I encrypt my android and suppose it loses or stole it, who finds it can unlock it for service by breaking the encryption password?

  22. Where encryption has been interrupted? I have a tephon that displays the next session "The encryption was interrupted and is not complete. As a result, device data is not available. / n / nTo use the tablet, You need to restore to the original settings. When you set the device after restore to factory settings, you can recover any data you have had a backup copy of in your Google account. "I have a button with" Reset phone "under the message, press it and nothing happens. Can I do something else?

    • Adrian Gudus said

      Yes, you can reset it from Recovery mode. In Recovery mode, go to the tablet and then press some button combinations when you turn it on. You did not tell us the model so I can not tell you which key combination to use to get to Recovery.
      I can just suggest you a method that you can try to access Recovery:
      - close the tablet (wait for it to close)
      - Press power and volume button - and keep pressed until it enters Recovery. With the volume button - select wipe data / factory reset and then press the power button to confirm in the next message, also with the volume button - select Yes and confirm with the power button.
      - Then select reboot system now and confirm with the power button again
