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.

WHATEVER YOU DO BEFORE FLASHING ANYTHING WITH TWRP MAKE A BACKUP OF YOUR DEVICE WITH TWRP AND HAVE THE STOCK FIRMWARE TO HAND JUST IN CASE DOWNLOADED FROM SAMMOBILE OR UPDATO.

THIS WILL TRIP KNOX AND MAY VOID YOUR WARRANTY!

Instructions:

(Note: failure to follow these instructions implicitly will cause TWRP to be replaced by stock recovery at boot!)

Flash with ODIN in the AP slot.

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 5.1.1/6.0/7.0 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.

Download:

twrp_3.1.0-1_sm-g532_5617b

IMPORTANT! This device enforces dm-verity. ANY modifications or even mounting system will put the device into a bootloop. To prevent this TWRP will ask at first boot if you want to keep system 'Read only' or 'Allow modifications to system'. If you choose to keep 'Read only' you will have to flash TWRP at every boot to recovery.

If you choose to 'Allow' then SuperSU or the boot patch needs flashing below to disable dm-verity.

To Root:

Flash the latest SuperSU release with TWRP:

https://xdaforums.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133/

This device forces encryption.

To disable forced encryption, mount internal storage(DATA) and disable dm-verity you must flash the boot patcher below:

(Note this MUST be flashed after SuperSU if you intend to root)

1. Boot to Twrp

2. Format Data partition using FORMAT DATA button under Wipe options.

(Note: This will wipe the internal storage)

3. Check DATA is mountable.

4. Install SuperSU (if root is required)

5. Install boot image patch below.

6. Reboot
