Introduction to dm-verity on Android

Android 4.4 introduced a number of security enhancements, most notably SELinux in enforcing mode and verified boot.

Android’s verified boot implementation is based on the dm-verity device-mapper block integrity checking target. Device-mapper is a Linux kernel framework that provides a generic way to implement virtual block devices. It is used to implement volume management (LVM) and full-disk encryption (dm-crypt). Device-mapper works by essentially mapping a virtual block device to one or more physical block devices, optionally modifying transferred data in transit. For example, dm-crypt decrypts read physical blocks and encrypts written blocks before committing them to disk. Thus disk encryption is transparent to users of the virtual DM-Crypt block device. Device-mapper targets can be stacked on top of each other, making it possible to implement complex data transformations.

In this context, dm-verity is a block integrity checking target: it was initially developed as part of the Google’s Chromium OS project with the purpose to implement a device mapper target capable of validating the data blocks contained in a file system. This means that it verifies the integrity of each device block as it is being read from disk. If the block checks out, the read succeeds, and if not the read generates an I/O error as if the block was physically corrupt. As for dm-crypt, this process is transparent to the applications reading those blocks.

The final purpose of dm-verity is to guarantee the integrity of a volume against corruption or malicious attacks.

Implementing dm-verity

Android 4.4 and higher supports Verified Boot through the optional device-mapper-verity (dm-verity) kernel feature, which provides transparent integrity checking of block devices. dm-verity helps prevent persistent rootkits that can hold onto root privileges and compromise devices. This feature helps Android users be sure when booting a device it is in the same state as when it was last used.

Potentially Harmful Applications (PHAs) with root privileges can hide from detection programs and otherwise mask themselves. The rooting software can do this because it is often more privileged than the detectors, enabling the software to “lie” to the detection programs.

The dm-verity feature lets you look at a block device, the underlying storage layer of the file system, and determine if it matches its expected configuration. It does this using a cryptographic hash tree. For every block (typically 4k), there is a SHA256 hash.

Because the hash values are stored in a tree of pages, only the top-level “root” hash must be trusted to verify the rest of the tree. The ability to modify any of the blocks would be equivalent to breaking the cryptographic hash. See the following diagram for a depiction of this structure.

In this guide, I have discussed Galaxy S7 dm verity verification failed error solution. This solution can also be used for Samsung Galaxy S6, S9 or any other Galaxy series phone.

Samsung Galaxy S7 and S7 edge are considered the finest phones of 2016. Even after the release of so many phones with better specs and operating system. People don’t want to change their S7 and move to S8. They are completely contented with it. Galaxy S7 is best in almost everything. From looks to hardware and specs. Everything is optimal. It has great camera quality and great processing power. There are two versions of Samsung Galaxy S7. International model is equipped with Samsung’s own Exynos 8890 processor. Whereas, the USA model is equipped with Snapdragon 820. Both models have 4 GB of RAM.

Currently, Galaxy S7 and Galaxy S7 edge are running on Android Nougat. But soon they will be getting Android Oreo update. As Samsung has started a Galaxy Beta programme. Where they are testing Android Oreo so that they can release a bug-free version to their users. Users of Galaxy S8 can opt for a testing program.

Update: You can install Android Nougat on your Galaxy S7 or Galaxy S7 edge using this guide.

Почему возникает ошибка «Host Key Verification Failed»

Основная причина, вызывающая ошибку Host Key Verification Failed», заключается в том, что ключ удаленного хоста был изменен и больше не тот, который хранится в файле «known_hosts». Ключ обычно меняется, когда серверы перестраиваются, и вы получаете сообщение об ошибке, как показано ниже:

Как убрать ошибку

Процедура по сбросу ошибки опасна для устройства, и лучше обратиться в сервисный центр для решения проблемы. Но если это невозможно, то работать придется на свой страх и риск.

Huawei-Multitool

Начать нужно с отмены изменений в системе, закрытия загрузчика и отката приложений, которые могут повлиять на смартфон. Чтобы сбросить ошибку можно воспользоваться компьютерной программой Huawei Multitool. В ней, во вкладке «Bootloader» нужно найти «Lock Status». Там отображается состояние загрузчика, если он «Разблокирован», нужно его заблокировать, выбрав «ReLock Bootloader».

Разблокируем устройство Xiaomi

Теперь программу нужно поместить в память устройства. Затем откройте пункт «Обновление, зайдите в меню, выберите пункт «Выбрать файл» и укажите программу, которую вы поместили в устройство. Лучше скопировать этот файл и другие важные данные, так как вся память устройства будет стерта после установки прошивки.

  1. Выключите свое устройство следующим образом: нажмите одновременно кнопку питания и громкости до появления режима Fastboot.
  2. Присоедините смартфон к компьютеру через USB.
  3. Запустите скачанную утилиту Mi Flash Unlock, подтвердите, что принимаете всю ответственность за устанавливаемую прошивку.
  4. В следующем окне введите данные регистрации на сайте (или Mi аккаунта) — пароль и идентификатор (ID).

Экран входа в Mi аккаунт

Теперь у вас есть возможность устанавливать Root-права для своего устройства, менять прошивку, устанавливать обновления при помощи Mi Flash, так как загрузчик разблокирован. Чтобы наглядно в этом убедиться — вы можете открыть окно статуса загрузчика, как мы это делали выше. Вы должны будете увидеть: device locked: true. Теперь мы точно знаем, что защита снята для любых дальнейших манипуляций со смартфоном, а сообщения This device is locked на гаджетах Xiaomi вы уже не увидите. Но будьте осторожны со сторонними прошивками, выбирать их необходимо внимательно иначе можно получить из работающего устройство безжизненный «кирпич».

How to Disable DM Verity without TWRP Recovery

The first valid question that might come to your mind is why we went ahead with this method. After all, you could easily disable DM Verity just by flashing a couple of ZIP files via TWRP. So this question becomes all the more justified. Well, the thing is not every Android device comes with a TWRP Recovery.

Furthermore, when one could easily root their device without TWRP and even Install OTA Updates in Rooted Android Device, why should we be dependent on TWRP for the aforementioned task. So for all the device owners that don’t have a working TWRP build or don’t wish to flash one, this method is all that is needed. Follow along for the complete instruction steps to disable DM Verity or Android Verified Boot (AVB) without using TWRP Recovery.

STEP 1: Get Stock Boot Image File

To begin with, you will have to get hold of the stock boot.img file. For that, download the stock firmware corresponding to your device and then extract the boot.img file from it. if the firmware is in ZIP format, you could easily extract it via WinZIP or WinRAR. In case, it is in OZIP format, then refer to our guide on How to Extract OZIP Realme and Oppo Stock ROM (Firmware). Likewise, if it’s in payload.bin format, then head over to the guide: How to Extract payload.bin and get the stock boot image file.

payload-bin-dumper-inside-python

OZIP ROM Extracted via Python

If you have a Xiaomi device, then maybe its firmware would be in GZ format. So rename it to TGZ and use 7ZIP to extract it. We also have a boot.img file for a couple of devices, if it meets your requirement, then you could directly download it without the need for extraction. The first one is Poco X3 NFC: Download Poco X3 NFC Stock ROMs | Fastboot and Recovery. Next up, is the OnePlus Budget offering: Download OnePlus Nord Stock Boot Image Files [All Versions]. If you aren’t able to get the boot.img file, let us know in the comments, we will help you out. With that said, let’s proceed with the steps to disable DM Verity or Android Verified Boot (AVB) without using TWRP Recovery.

STEP 2: Install ADB | Enable Debugging

First off, you will have to install Android SDK Platform Tools on your PC. This will provide you with the necessary ADB and Fastboot binary files. After this, install Magisk Manager on your device. Along the same lines, we would request you enable USB Debugging as well. This will make your device recognizable by your PC in ADB mode.

На каких устройствах и почему появляется надпись «Your device is corrupt»

Чаще всего проблема возникает при:

  • Обновлении системы смартфона.
  • Длительном отсутствии апгрейта устройства (например, когда пользователь принудительно откладывает обновления).
  • Приобретении дешевого телефона в сомнительном интернет-магазине. Дело в том, что многие бюджетные модели смартфонов производятся в Китае, на не самых известных фабриках. На таких производствах нередко экономят и устанавливают программное обеспечение как попало.

На экране надпись

Разумеется, если телефон не оригинальный, то на нем также может появиться ошибка «Ваше устройство не может работать корректно». Также проблемы могут возникать на телефонах, в которых используется не привычная ОС Андроид, а видоизмененная.

Как правило, единственный доступный пользователю метод исправления такой ошибки – это перепрошить смартфон. Лучше всего для этого обратиться в сервис, но если такой возможности нет или вы хотите попробовать свои силы, то можно попробовать.

Your device has failed verification and may not work properly

На смартфонах Huawei и Honor пользователь взаимодействует с операционной системой через интерфейс под названием EMUI (Emotion UI). Компания Huawei специально разработала его для своих гаджетов, функционирующих на Android, чтобы упростить обращение юзера к ОС .

В большинстве случаев автоматические обновления системы проходят без проблем. Иногда же процесс апдейта сопровождается ошибками, на экране появляется надпись “Your device has failed verification and may not work properly”. Что делать, если появляется такое уведомление и как от него избавиться расскажем в этой статье.

Что значит эта надпись

“Your device has failed verification and may not work properly” переводится как “Устройство не прошло проверку и не может продолжить работу”. Ниже предлагается выбрать одну из трех команд:

1. Нажать кнопку «Power», после чего просто включится смартфон и им можно будет пользоваться дальше. Однако при перезагрузке устройства или попытке обновить ОС надпись будет снова появляться.

2. Восстановить операционную систему. Для чего нужно зажать громкость “плюс” и подержать 3 секунды.

3. Остановка старта.

Your device has failed verification and may not work properly на экране Huawei

Причины почему на экране Huawei и Honor выскакивает текст Your device has failed verification and may not work properly могут быть различные.

Наиболее распространенные:

  • Производилось рутирование устройства.
  • Разблокированный загрузчик EMUI.
  • Включение функции FRP (Factory Reset Protection – система защиты от кражи на устройствах, работающих на базе Android).
  • Установка модифицированного Recovery.
  • Использование прошивки, отличной от оригинальной.

Что делать, если на экране Honor появляется Your device has failed verification and may not work properly

При самостоятельном выполнении операций с настройками техники всегда присутствует определенный риск. Если Вы сомневаетесь в способах, рассмотренных в этой статье – не рискуйте и обратитесь в специализированный сервис.

Разблокированный загрузчик

Наиболее популярная причина – производилось разблокирование загрузчика. Если вы покупали телефон “с рук”, возможно это сделал предыдущий владелец Вашего Honor. Для открытия Bootloader чаще всего используют такие сторонние программы как MiFlashUnlock, Huawei Multitool, Adb Run. С их помощью можно выполнить и обратный процесс.
Популярностью пользуется Huawei Multitool.

Чтобы вернуть загрузчик к первоначальному состоянию следуйте инструкции:

  • установите Huawei Multitool на компьютер и подключите к ПК смартфон;
  • активируйте программу и откройте в ней вкладку «Bootloader»;
  • далее зайдите в меню «Lock Status» и посмотрите состояние загрузчика интерфейса;
  • если он разблокирован, то измените на «ReLock Bootloader».
Активная функция FRP

Спровоцировать появление надписи также может активный режим FRP.

Выключить его можно следующим образом:

  • Настройки – меню «О телефоне» – найдите номер сборки интерфейса EMUI – тапните по нему 7 раз. После этого включится режим разработчика, там деактивируйте функцию FRP.

Появление уведомления на “чистом” Huawei

Если надпись вылазит на новом смартфоне, на котором не производилось рутирование, загрузчик не разблокирован и вообще начальные настройки никак не менялись – скорее всего это просто сбой при обновлении.

Устранить его можно включением режима eRecovery:

  • предварительно сохраните важные данные, например, перекиньте на флешку (т.к. они удалятся);
  • подключите устройство к ПК, выключите смартфон, одновременно зажмите «Power» и громкость “плюс”, и держите до срабатывания сигнала вибрации;
  • после этого включится режим “eRecovery”, выберите «Download latest version and recovery», устройство запросит Wi-fi сеть.

eRecovery в Huawei

Начнется автоматический процесс загрузки последних установок, во время которого смартфон может сам перезагрузиться несколько раз. Просто подождите пока устройство
самостоятельно выполнит все операции.
