As per https://android.stackexchange.com/a/78183/239063 you can run a one line command in Linux to add in an appropriate tar header to extract it.

( printf "x1fx8bx08x00x00x00x00x00" ; tail -c +25 backup.ab ) | tar xfvz –

Replace backup.ab with the path to your file.

I have had to unpack a .ab -file, too and found this post while looking for an answer. My suggested solution is Android Backup Extractor, a free Java tool for Windows, Linux and Mac OS.

Make sure to take a look at the README, if you encounter a problem. You might have to download further files, if your .ab -file is password-protected.

У вас есть резервная копия userdata_*.backup созданная в стоковом Recovery Andro >

Сайт Android +1 (этот, а не его клоны), замечателен тем, что здесь находиться уникальная информация, которая доступно изложена. В этот раз мы приготовили очередной полезный материал.

Если вы разбили дисплей или у вас установлен графический код, а может быть пин-код, то возможно вы сможете извлечь необходимые данные с помощью резервной копии созданной в стоковом Recovery Android. Об этом мы уже рассказывали вам в прошлой статье, рекомендуем ознакомиться — как создать бэкап Android стоковым Recovery.

Теперь в этой статье мы расскажем вам как вскрыть бэкап, с помощью 2 способов.

Способ 1. Открываем резервную копию userdata_*.backup

  1. На компьютер загрузить 7-zip архиватор и установить его
  2. Переместите резервную копию userdata_*.backup
  3. Правым кликом по резервной копии вызовите дополнительное меню и выберите «Открыть с помощью» и указать «7-zip»
  4. После чего вы можете извлечь все данные из архива

Если userdata_*.backup при попытке открыть его через 7-zip не увенчалась успехом, переходим ко второму способу.

Способ 2. Открываем резервную копию userdata_*.backup

Прежде всего вам необходимо будет установить на компьютер Ubuntu Linux или создать виртуальную машину с Ubuntu Linux (расскажем позже).

  1. Все Файлы резервной копии userdata_*.backup переместите в Ubuntu
  2. В папке где находиться резервные копии сделайте правый клик мыши на свободной области и в появившемся меню выбрать «Открыть в терминале»
  3. Далее вводим команду с помощью которой мы создадим из текущих файлов userdata_*.backup в образы
    dd if=userdata_ваша_дата.backup of=part .img bs=512 skip=1
    dd if=userdata_ваша_дата.backup 1 of=part 1 .img bs=512 skip=1
    dd if=userdata_ваша_дата.backup 2 of=part 2 .img bs=512 skip=1
  1. Теперь необходимо создать из всех частей образов один целый образ
    cat part*.img > backup.img
  2. Теперь необходимо примонтировать данный образ к системе, чтобы мы могли увидеть что находиться внутри
    sudo mount -t ext4 backup.img /mnt
  3. Теперь необходимо запустить файловый менеджер под root правами чтобы можно было полностью открыть все что нам необходимо
    sudo nautilus
  4. Переходим по пути /mnt и видим кучу папок которые являются данными вашего backup файла

Извлекаем данные, где что?

Все файлы видео, фото, видео, аудио, документы, можно найти в папку /media/o/. База данных контактов можно найти по пути data/com.android.providers.contacts/databases/ файл contacts2.db (как извлечь контакты). Приложения находятся в /app/.

Taking a backup of your Android device is of utmost importance. Nobody likes to lose their crucial data while facing an unforeseen situation. A lot of people assume that one can backup their data only by rooting their device. If your device is not rooted, then don’t worry. There are plenty of options for one to backup their important data and restore it whenever required.

We will help you backup your data without any trouble using an Android extractor. If you use an Android device and would like to make sure that all your data remains safe, then you got to make an effort. Follow our suggested approach and secure your data from any unexpected loss.

Part 1: How to Make ADB Backups

One can easily backup their data using an Android backup extractor. If your device has Android 4.0 and above, then you can easily follow these easy steps. Though, it works for other versions as well, but the approach could be a little different. Start by getting familiar with the Android SDK tool as it will come handy to you on various occasions and follow this foolproof process to save your data on your computer in a trouble-free manner.

1. Commence by installing the latest version of the Android SDK toolkit. This will help you access your device in a whole new way.

2. Simply open Android Studio and click on “SDK Manager”. Now select the “Android SDK Platform tools” to install all the essential packages you would need.

3. Select the packages you want to have and click on the “Install” button.

4. As soon as the process gets complete, pick your Android device and go to “Settings”. Click on “About phone/tablet” option.

5. Now you would be required to tap “Build number” a certain amount of times (most probably 7) until it would say “You are now a developer.” Congratulations! You have already taken the first step to work on the android extractor.

6. Again, go to “Developer options” and set the “USB Debugging” option to “on”.

7. Simply connect your Android device to your computer using a USB cable.

8. Open the terminal prompt and make sure you have the Admin rights. Now, navigate to the ADB’s location. Usually, it is located at: C:UsersusernameAppDataLocalAndroidsdkplatform-tools

9. Depending on the type of backup you want to attain, you can type either of these commands – adb backup-all or adb backup -all -f C:filenameichoose.ab. The first command will backup all the data from the device to a folder backup.ab while the second one can be used to backup data from an Android backup extractor to a certain file location.

10. You can also switch command accordingly. –apk can be used to backup your app data, -noapk won’t backup app data, -shared will backup data on the SD card while –noshared won’t backup data on the SD card.

11. After typing the chosen command, press Enter and it will make the following screen appear on your device.

12. The screen will ask you to provide a password for your backup. Provide a respective password and tap the “Back up my data” option for the process to commence automatically.

2. Connect your device and follow the same initial process as above.

3. Instead of giving the backup command, make sure you give “adb restore” instead and the initial file location. For example, “adb restoreC:UsersusernameAppDataLocalAndroidsdkplatform-tools”
