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 1/4/2017
TWRP 3.1.0-1 MM/NN build released.
Current status: BETA

Features:

MTP working
ADB working
SEANDROID warning fix
TWRP and Kernel built from source
System image backup
F2FS support >> To be added
Twrp app support

Bugs:
Reboot to recovery loop when using reboot utilities. Use hardkeys combo only to boot to recovery POWER + HOME + VOL UP
If you get stuck in a recovery loop reflash TWRP with auto-reboot enabled.




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 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.

Does rooting require a permissive kernel?

Does rooting require a permissive kernel?

Rooting doesn't, custom recovery might.
I don't know yet until someone reports.

 

[dalingrin]

I was able to both flash TWRP with Odin as well as root the device.

I was not able to mount /data in TWRP however.
I couldn't use adb shell while in recovery due to a libc.so not found error. ADB did work in the Samsung provided Android 6.0.1.

I've attached the recovery log as well as the kernel log.

I was not able to mount /data in TWRP however.

I'm not sure, but could this be caused by enabled encryption

As far as I know Android devices which are sold with 6.0.1 by default need to be encrypted

Thanks for testing and posting the logs. @York2k16 Correct the error mounting data is because of encryption. Twrp is unable to find the encryption key.
It's true Android 6 devices are encrypted by default, but don't need to be.

Work around for now would be not to use encryption until I find the solution.

The issue with adb is because of Samsungs stock kernel.
I need to recompile it with root protection removed.
Unfortunately no sources are available as yet.

Well at least we have a working recovery and a root solution.

Can you confirm a few things:
UI orientation, portrait or landscape?
UI colour?
All other options and features working correctly?

Thanks, well done for probably being the first in the world to have a rooted S2 VE 8.0

Few weeks ago I've tested the T813 and returned it back after a few days. I'm going to buy the LTE model soon or when the prices go down a bit.

Checking the security settings menu I've realized that there is no option for enabling/disabling device encryption, only SD encryption.
@dalingrin: Is this the same case on your device?

This "issue" would open up another question: How do I decrypt a device, which is encrypted by factory default, but doesn't offer any options to disable/enable encryption?

 

[whynottoday]

TWRP does not work properly on T813. I am unable to use it because can not click on buttons

you need to format the data partition in TWRP to remove encryption.

How about a little more constructive detail like I asked for?
What orientation is the GUI, is it landscape or portrait. Are the touches simply misplaced?

 

[ashyx]

@dalingrin
Does this at least ask for the encryption password?

Also whilst in the android OS could you post me the output of
ls -l /dev/block/bootdevice/by-name/

Thanks.

Oh sorry
So it is landscape and yes it seems that touches are misplaced. Thanks

Mount issue, you mean data?
Can you post the recovery.log.
You will find it under Advanced in twrp.
