TeamWin Recovery Project: Unterschied zwischen den Versionen

The '''TeamWin Recovery Project''' (short '''TWRP''') is an alternative, manufacturer-independant [[Recovery]] systems<ref>http://teamw.in/project/twrp2</ref> for several [[Android]] devices. It is based on the [[AOSP]]-Android-Recovery, extended with several features and it's own user interface. The Recovery is fully touchscreen-based and can not be controlled using the volume keys (up and down) as well as not with the power key to select menu entries.

In difference to the [[ClockWorkMod]], TWRP provides a built-in [[file manager]], different themes as well as other advanced options for backup, wipe and restore (e.g only backup or restore some partitions, bypass the MD5-checksum creation or choose an own name for a data set like backups). The installation of zip files provides a way of adding multiple zip files (up to 10) in a so called ''Batch-Job'', which are processed one after one.

To use the TeamWin-Recovery, it has to be installed on the device. This is done with the [[fastboot]] command "flash". It's required, that the [[USB driver]] for the device is installed correctly and that the fastboot.exe is present, which is, e.g., shipped with the [[Android SDK]], but can also be installed standalone. The recovery itself can be retrieved/downaloded as an image file (*.img). This file needs to be copied in the same directory where the fastboot.exe is saved in (for simplicity) and renamed to ''recovery.img''.

Afterwards, a command line window is opened <nowiki>[WINDOWS] + [R] -> "cmd" -> [RETURN]</nowiki>) and, within this window, navigated to the directory, where the fastboot.exe is saved in (you can use the windows command to navigate through directories in the command line, followed by the directory path, e.g.: ''cd C:\android\fastboot'').

To proceed, the android device needs to be connected to the computer using the USB cable, followed by executing the following command in the same command line window, which was used before::<pre>

</pre>After the successful flash of the recovery (which is noted with a success message in the command line window), the device can be started into the recovery-system out of the [[bootloader]]. The TeamWin Recovery is now installed successfully.

If the android device is started in the TeamWin recovery, you can execute [[ADB]] commands against the device. If, during the use of the adb, the command is rejected with the message ''device not found'', you should check, if the correct USB drivers for the device are installed, and, in case of using the Windows operating system, you should check, if the device is correctly recognized in the Windows device manager.

Because the engine is open-source and licensed under a free license, it can be used by anyone for anything, which was an advantage over the '''[[extendedcommands]]'''implementation, which was used in the [[ClockWorkMod]].<ref>{{Cite web|url=http://wiki.rootzwiki.com/OpenRecoveryScript|title=OpenRecoveryScript - RootzWiki|accessdate=2015-02-28}}</ref>

Using a simple text file, saved in the ''/cache/recovery/'' directory with the name ''openrecoveryscript'', the recovery can be instructed to execute the described set of commands during the startup, e.g. the installation of a zip archive such as a [[ROM]], or the deletion of a [[partition]].
