Special Notes:
1. DON'T FORGET TO ENABLE "OEM UNLOCK" (located in Developers options).
2. KNOX will be tripped once you flashed custom binaries to your phone.
(Your warranty may be voided. However this may not affect you if your country, European Union for example, forces Samsung to provide hardware warranty regardless of software status.)
More Infos: https://en.m.wikipedia.org/wiki/Rooting_the_Android_operating_system
3. Samsung Firmware OTA (aka System Updates) will no longer work once you flashed custom binaries.
(You can flash custom ROMs if you want to keep the OS up-to-date.)
4. It is HIGHLY UNRECOMMENDED to purchase any access to any kind of private forums, ROMs or Kernels.
(DO NOT GET FOOLED.)

Guides:
Notice: It may wipe all your data including those in internal storage.
Part 1 - HOW-TO FLASH TWRP:
1. In your ROM, go to Settings -> About device. Tap 7 times on Build number to enable Developer options.
2. Go to Settings -> Developer options and enable OEM Unlock option.
3. Download and Install Samsung Mobile Phones Drivers.
- Option 1: Download and Install Smart Switch for PC.
- Option 2: Download and Install standalone driver package.
4. Download and extract Odin (Samsung's Flash Tool) to your computer.
5. Download a .tar image of TWRP.
6. Reboot your device to download mode.
- Hold [VOLUME DOWN] + [BIXBY] + [POWER] for approx. 15 seconds.
- Read the warning carefully.
- If you agree, press [VOLUME UP] to get into Download mode. If you don't agree, STOP.
7. Open Odin and place that TWRP tar file in the [AP] slot.
8. Connect your phone.
9. Hold [VOLUME UP] + [BIXBY] + [POWER] on your phone and then press start on Odin.
10. Wait for the phone to reboot. DO NOT release [VOLUME UP] + [BIXBY] + [POWER] or you may not reboot into TWRP.
Part 2 - HOW-TO INITIALIZE TWRP: (for new phones)
1. If you completed Part 1 successfully, you should be in TWRP now. At this point, you will reach the screen asking you if you want to allow system modifications.
2. Select "Keep /system RO". (Don't swipe right or you may not be able to boot into system if you failed to complete next steps. However, you can swipe right to allow modifications if you are confident that you can complete next steps.)
3. Go to "Wipe" menu of TWRP and you will find "Format Data". Press "Format Data" and type "yes" to continue.
4. Go to "Reboot" menu and Press "Recovery" to reboot TWRP.
5. Download the latest dm-verity and force encryption disabler zip on your computer.
6. Transfer the zip to your phone.
- Option 1: MTP: Connect your phone with computer and just copy the zip to internal storage. (similar to how you transfer files when in system.)
- Option 2: ADB: Connect your phone with computer and run command "adb push /path/to/zip /sdcard/".
- Option 3: External SD: Copy the zip to an external SD and then insert the card to your phone.
7. Go to "Install" menu of TWRP and flash the zip.
TWRP is initialized and fully functional at this stage. Now you can either reboot into system or root, flash custom ROMs via TWRP.
Part 3 - HOW-TO ROOT:
1. Download the flashable zip.
- Option 1: Magisk
- Option 2: SuperSU (untested)
2. Transfer the zip to your phone.
3. Go to "Install" menu of TWRP and flash the zip.
Part 3a - HOW-TO FLASH CUSTOM ROMS:
1. Download the flashable zip.
2. Transfer the zip to your phone.
3. Go to "Install" menu of TWRP and flash the zip.
Simple.

Yes you will, make sure you've backed-up as much as you can to your Google Cloud Storage. I promise, it's worth it.

Many Thanks

And if i just install TWRP, and then the root zip file to give me root will it all work ok? will i achieve root ok?
I spent ages getting this phone just like i want it and seriously cant be bothered to do it all again - will i be ok keeping encryption on if all i want to achieve is root?
what will i lose out on if i dont disable encryption?

I found that if I didn't disable the encryption, root wouldn't work as it couldn't mount the file system to make the relevant changes

Anyone managed to get Samsung Pass and Secure Folder working? I have Magisk Hide running and Knox Trip is emulated to 0x0. Other apps that would normally detect root don't detect it but Samsung Pass and Secure Folder still can.

---

Is superSU SR3 working??

---

its a great work

---

anyone tried if Samsung Pay still works after this? I have not got my phone yet.

---

Just for info tried installing the SuperSU binary through TWRP but, as TWRP seems to have no access to the SD card, the flash failed and left me in a boot loop.
Reinstalling TWRP from Odin and reflashing Magisk solved the Boot loop issue.
SuperSU did kill the Knox processes for me though to stop the annoying nagging notifications.

---

If after flashing from Odin, phone says that needs restore, Just press volume up Bixby Power, wait, then format data, Power off. Now ho back in download mode, reflash with odin, done.
It works all', except personal area and Samsung health

---

would this work on the SM-G950FD?

---

if i use this method i lose warranty ? is it possible to do evrything later on normal without having any trouble ?

---

Phone brick...LOL...

---
