TeamWin has launched its next major custom recovery update, TWRP 3.4.0. Available for a large number of devices, this new release addresses multiple aspects including support for Android 10. For Android enthusiasts, especially those who run custom ROMs and other system mods, TWRP serves as an essential installer utility. It not only allows for ZIP files to be flashed directly on the phone but has advanced built-in functionality such as system partition wiping. Learn more about what’s new with TWRP 3.4.0 right ahead along with different available download methods.

With each new Android iteration, modders and developers are faced with a challenge of carrying over existing mods to the newer release. Same is the case with TeamWin’s recovery project, it needs to redone in order to work with latest Android standards. For 3.4.0 release in particular, it is the first step towards providing full support for Android 10. While it doesn’t work on phones that have shipped with Android Q out of the box, it, however, works with legacy devices that got updated to Android 10 via a software update from Android 9. This increased Android version compatibility isn’t all that’s new with TWRP 3.4.0, there are tons of other revisions present as well — which we will discuss ahead.
