Official TWRP App
Mar 11, 2017

Official TWRP App
The official TWRP app is the first and only first-party app developed by Team Win for TWRP. Please bear with us as we work to fix any bugs and build out the features. The initial version of the app does not support flashing on the Pixel due to the Pixel’s A/B partition layout. In addition, the app may not support finding and flashing images from external storage locations. We are working hard to improve these items and bring you more new features.
Download Links:
We recommend downloading the app from the Play Store.

If you do not have Play Store access, you may download the Official TWRP App here: https://dl.twrp.me/twrpapp/
How do I use the app?
When you first open the app, you will be greeted by a few options. First, you will need to agree not to hold us responsible for anything that happens to your device while using the app. You may also grant the app root permissions. The app will work without root, but some functionality like image flashing will be disabled. Lastly, you can opt into enabling InsightCore (more on this feature later).

Once you have passed this initial screen, you will be greeted with the app home screen where you can choose TWRP FLASH or NETWORK STATISTICS (more on the network statistics later). On the TWRP FLASH screen you will need to select a device. Once you have selected a device, the app will periodically check for new TWRP versions for the device that you have selected. The default interval is once per day, but you can tap on the settings icon in the upper-right to change the interval or disable the update check entirely.

If you enabled root access, you will see options for selecting an image and buttons for flashing the selected image to boot or recovery. Note that you should flash TWRP images to recovery. The boot image flashing is for flashing full boot images (not just kernel zImages) and should not be used for flashing TWRP.

Update 12/4/2017
TWRP 3.1.0-1 MM build released.
Current status: BETA
NOTE: THIS IS CURRENTLY IN THE TESTING STAGE, THERE MAYBE BUGS, IT MAY NOT BOOT AT ALL. I DON’T OWN THIS DEVICE. I CAN’T FIX ISSUES IF PEOPLE DON’T POST RECOVERY LOGS OR PROPERLY DESCRIBE THE ISSUE. STOCK RECOVERY IS PROVIDED BELOW IF NEEDED.

Features:

MTP working > to be confirmed
ADB working > to be confirmed
SEANDROID warning fix
TWRP and Kernel built from latest source
Factory Image flashing(see below)
NTFS support
F2FS support >> To be added
Twrp app support

New feature available in TWRP v3 is system image backup and restore and factory image flashing (see TWRP changelog for details)
Basically this means factory images from the official firmware can now be flashed with TWRP instead of ODIN. I have extended this feature to include BOOT, RECOVERY, SYSTEM, CACHE, HIDDEN and RADIO(MODEM) partitions.
This feature can be found under INSTALL >> INSTALL IMAGE >> select image to flash >> select partition.
NOTE: To flash the modem, first it needs to be renamed to modem.bin.img
Issues:
Current versions of SuperSU seem to be incompatible.
You flash this at your own risk. Please ensure you have the stock ROM to hand downloaded from SAMMOBILE in case of problems. This will trip the knox counter.
Instructions:

Flash with ODIN 3.10.7.
Put your device in DOWNLOAD mode.
Uncheck Auto reboot.
Load the respective file below into the AP slot and hit start.
After flashing and ODIN reports PASS immediately reboot to recovery by holding POWER + HOME + VOL DOWN.
As soon as the screen goes blank change to VOL UP whilst still holding POWER + HOME.
You should now see TWRP recovery.

NOTE: ON SOME ANDROID 5.1.1/6.0 DEVICES IT IS NECESSARY TO GO TO:
Settings -> Developer Options -> OEM unlocking
AND ENABLE OEM UNLOCK FIRST OR YOU MAY ENCOUNTER ‘BLOCKED BY FRP LOCK’ WHEN FLASHING.
