If you want to flash ROMs or random ZIP files to your device, you're more than likely going to use TWRP. This is the most widely supported custom recovery for Android, but it's been a while since it got a big update. The 3.0.0 release is just about ready, and it brings a ton of changes, not the least of which is a new theme that's more in keeping with Android's current look.
The tireless developers at Team Win released their custom Android recovery for the Nexus 6Pand Nexus 5X last week, but at the time it didn't support decryption. This makes working with the stock software (which Google encrypts by default, gleefully thumbing their noses at the NSA and FBI in a show of customer protection) somewhat tricky. But ROM flashers and phone modders can now use the latest version of TWRP on the Nexus 6P with the encrypted stock software, or any other ROM that uses the feature. The latest version is 18.104.22.168.
Say what you will about the OnePlus 2 (and we certainly have), it's perhaps the most likely phone released this year to be modified by end users, with the possible exception of the new Nexus devices. So it's a good thing that all those tinkerers and ROM flashers now have a reliable way of applying updates and making backups. Team Win Recovery Project, better known as TWRP, is now available in a OnePlus 2 flavor. It's version 2.8.7, the latest stable release.
At this point the TWRP custom recovery is probably the most popular among the many recovery options available across a wide variety of Android devices.
Like it or not, CyanogenMod is still one of the most popular, well-supported custom ROMs out there. However, downloading the necessary files to flash it could be an exercise in frustration. See, the CM download page only listed device code names, but now it uses the device names you actually know.
Chances are that if you're in the recovery interface of your phone, it's because you broke something, need to force an update, and you're just fiddling with things. The stock recovery doesn't have a ton of options, which is why alternatives like ClockworkMod and TWRP exist. Still, the stock recovery in Android M is a little more capable than before.
If you're a frequent ROM flasher (why does that sound mildly dirty?) and a OnePlus One owner, you might want to grab the latest build of TWRP. A Team Win developer says that it now supports Qualcomm's native encryption scheme in addition to Android's standard AOSP encryption. Why does this matter? According to Ethan "Dees Troy" Yonker and cited benchmarks, Qualcomm's encryption offers better performance when compared to Google's encryption applied to the same hardware.
...for slower encryption methods.
The hardware-based encryption offers an approximate 30% boost to read-write speeds over Android's software encryption, though it's still well below the performance of unencrypted flash storage.
Sony is continuing its odd support for modifications and software based on Android's open source core. Today they're releasing a collection of flashable recovery partitions for some phones - technically these count as "custom" recoveries, but they're based on AOSP, and therefore pretty close to what you'd find on Nexus devices. Sony's intro video does state that the recovery can restore data, flash custom ROMs, and boot to multiple ROMs, something that most stock recoveries can't handle.
The new recovery is available on the Xperia Z1, Xperia Z1 Compact, Xperia Z Ultra, Xperia T2 Ultra, Xperia T3, Xperia M2, and Xperia E3, all of which need to be unlocked at the bootloader level and running the latest "generic" software from Sony.
Owners of the Sony Xperia L have something to celebrate today. No, it's not actually all of their birthdays on the same day, possibly because of a breach in the space-time continuum. TWRP is now officially available on the Sony Xperia L.
The Nexus 9 is still a new device, but it's a Nexus, and that means developers are going to tinker with it. In order to flash ROMs and whatnot, you need a custom recovery. Now there is one for this device. An official build of TWRP is live, and it brings some changes that take into account Lollipop's new security measures.
To get any serious modding done with an Android device, you need a custom recovery like TWRP. It's sort of a rite of passage for every new phone to get its own official build of TWRP, and today is the Note 4's big day. TWRP is now available for this device, but not for all variants just yet.
