TWRP Recovery FAQ
1.What is twrp?
twrp stands for Teamwin Recovery Project. It is a GUI based custom touch recovery.
twrp allows the following functionality:
In tar or raw image formatbackupPartition
Restore backups from internal storage, external SD storage or OTG devices
Custom firmware installation
Partition wiping
FileDelete
Terminal access
ADB root shell
Theme support
2. Why doesn’t twrp support encryption on my device?
Two stages support twrp encryption. The first is to keep up with the latest support from AOSP, which may require a lot of changes and integration with new AOSP versions. This may take some time, especially if we have to wait for a reference device to test. The second item is custom blob support and integration with device OEM firmware.
Even if your device supports AOSP encryption and decryption, it usually requires custom blob support. The process of resolving this issue may take time and may never be completed. Some vendors (such as Samsung) use their own encryption technology. Without a lot of deconstruction/unpacking of custom library chunks, and successful ports by active maintainers, this might never have been possible. In twrp, encryption support is a nice option rather than a must-have support option. We think the ability to back up your system and install custom firmware is more important than the complete lack of TWRP support.
3. Recovery mode creates a new file in the cache/recovery directory. After restarting, the new file disappears. Why?
Detailed description:
1. Create a new file /cache/recovery/wetest at the end of the recovery.cpp file; and write the content: welcome to recovery mode!
2. Compile the version, burn the phone, and after booting, restore the factory settings; wait for the phone to enter the automatic restart state, and before the boot wizard pops up, use the command to enter /cache/recovery/. There is a wetest file, and the content is correct; but after the boot wizard is completed, and then enter /cache/recovery to view, the generated file disappears.
The reason is:
After the boot is completed, frameworks/base/core/java/android/os/recoverysystem.java will determine whether the files under the /cache/recovery directory start with "last_". If not, they will be deleted. The purpose is to allow the directory to store only a few files specified by the recovery mode.
If you must create a new file in this directory, please be sure to add the prefix "last_" before your file name to avoid being deleted after restarting.
4. How to use pgp to verify twrp files?
Recently, we implemented signing of twrp files using OpenPGP for security-conscious people who want to verify the non-repudiation of twrp.me files. You can read more about OpenPGP here
VerifyKeyIn the ring. The public key is also listed on each device's download page. Please download the key to a new file. When you click on the page you will
The link to the PGP verification file is "Download PGP signature twrp device version.type.asc". This file is in binary format and is created using the private key the first time a download page is created for the file. You can then perform the following steps to verify non-repudiation (Linux steps only):
gpg—import twrp-public.asc
gpg—verify twrp-device-version.type.asc twrp-device-version.type
For Windows, please find the OpenPGP implementation and read the documentation to perform these steps.
