TWRP v3.1.0 is now Rolling out with Support for ADB Backup, A/B OTA Zips, and More
About two weeks ago, we were informed that the next version of TWRP would bring support for backing up files directly to your PC through a feature known as ADB backup. We were told that this version of TWRP would be labeled version 3.1.0 and would roll out sometime soon. That time is now. Version 3.1.0 is rolling out with the aforementioned ADB Backup feature along with a couple of noteworthy fixes.
In particular, the update brings support for flashing alpha/beta OTA update zips through the recovery. Currently, this would only be useful for users on the Google Pixel or Pixel XL, but as more devices begin shipping with Android 7.1 and the A/B partition scheme, more users can take advantage of this feature. Owners of certain HTC phones, though, can now rejoice as the update brings better support for decrypting the data partition on some phones.
Another major fix to note is that TWRP will no longer wipe the data of certain applications that are set up for the Direct Boot feature, a bug which some users noticed when attempting to backup and restore their favorite messaging apps only to find that all of their messages were missing. Without going into too much detail, the gist of this problem is that applications set up for the Direct Boot feature make use of Device Encrypted (DE) storage rather than Credential Encrypted (CE) storage. Android 7.0 began adding certain extended attributes (xattr) to the data folders of apps stored under DE storage, but backups made via TWRP were not saving these xattrs prior to this update. Hence when a user attempts to restore the data folders from backups missing these xattrs, Android would instead delete the entire data folder.
Finally, one other change we would like to point out is that TWRP will now ask you to install the official app before rebooting. This request, which can be disabled permanently if declined, is a way for users to keep TWRP up to date on their device and to support the awesome team behind the recovery. If you haven’t already, check out their app on the Play Store!
There are some other changes that we didn’t mention, but you can look through a summary of the (massive) change-log for this update below.
