For all those with P2C72 version that came with a42 ROM (version S048) that cannot get Nougat OTA, here's how you can manually do it:
1. Download this file. (1.91GB)
2. Rename the downloaded file to "update.zip". (The file you download is already in zip format, so if you do not have Windows set to show file extensions, just rename to "update").
3. Copy the file (update.zip) to the root of your sdcard that is already in the P2.
4. Turn off the phone. Hold "Vol Up + Vol Down + Power Button". Release the "Power Button" when the phone turns on. The recovery mode will load in about 3 to 4 seconds.
5. In the recovery mode, select "Install Update Package", then "Yes".
6. Allow the phone to restart when the update procedure ends. You're now running Nougat version S232.
7. To get the version S233, download this file. (78.3MB)
8. Repeat steps 2 to 6. (Delete or move the first update.zip to another folder)
9. Time to do a factory reset. Enter the recovery mode. Choose "Wipe User Data". First do "Fuse Wipe Data", then "Fuse Format Data", and finally "Wipe Cache", all the while selecting "Yes" when asked.
10. If you have not already "applied" to have your bootloader unlocked, you can do that now.

Welcome to my guide on how to install XPOSED on the Samsung Galaxy S4 (SGH-1337M) this guide is strictly for the SGH-1337M the reason I made this was because I spent a lot of hours trying to put parts of threads together since no one had specifically made a guide that was simple and noob friendly for installing XPOSED. Another reason is some people feel uncomfortable following guides made for the SGH-1337 mainly because it is different from the SGH-1337M. Another reason was I found no updated 2016/2017 guides for it. Follow every part step by step or you may risk losing your phone.
Also make sure you backup anything that isn't synced with Google that you want to keep, photos, music, contacts. This will delete all data on the phone.

I tried it, but it didn't work. I think I downloaded a bad firmware tho. I am going to try it now. Btw. if you want an easy firm download I highly recomend Frija v.1.3.0. - only easy, fast and WORKING (at least for me) firmware downloader.
I am stuck at odin saying NAND Write Start!!.
Could anyone help me?
(EDIT)
OneUI 4.1 has finally arrived, if you haven't got your Tab s6 rooted, you can just follow the instructions below. This new part is for the people who followed the guide to root their Tab s6 and now want to update to the new firmware version without losing their data. This guide is inspired in https://forum.xda-developers.com/t/...te-rooted-device-whilst-keeping-data.4245989/. But for simplicity of search I have decided to place it here
(END OF EDIT)
I ran into some problems and took some time to figure out how to install TWRP and root the tablet. The normal procedure by which you flash TWRP and then flash Magisk doesn't work as the download mode won't accept non-official files.
Then, once I got my tablet rooted by the patching method of Magisk, I installed TWRP with their app and got stuck in the logo due to not formatting the data.
After some research and quite a lot of time, I managed to get around that and be able to do everything.
Here is a step by step detailed guide of how to do so.
ATTENTION: These modifications void your warranty and may brick your device. I am in no way responsible for any damage you may cause. Follow this guide at your own risk
Requirements:
-> Latest version of the firmware of your model (I used this site which had the latest version and decent download speeds https://galaxyfirmware.com/model/SM-T860)
(To find which version to download, go into the Phone app, and type *#1234#)
-> Latest Magisk.apk file (https://github.com/topjohnwu/Magisk/releases)
-> Disbale_Dm-Verity_ForceEncrypt zip file (https://zackptg5.com/android.php#disverfe)
-> Latest TWRP img (https://eu.dl.twrp.me/gts6l (europe) or https://dl.twrp.me/gts6l (americas))
-> Official TWRP tool (Play Store)
-> Samsung drivers (https://developer.samsung.com/android-usb-driver)
-> Latest Version of Odin (https://odindownload.com/SamsungOdin)
-> SD Card or Minimal ADB and Fastboot (https://forum.xda-developers.com/t/tool-minimal-adb-and-fastboot-2-9-18.2317790)
(If SD card)
Copy Magisk, AP file from the firmware zip, Disable_dm zip and TWRP img into the SD card, else, you will have to use adb sideload
0. Create a backup of all your data (we are going to wipe the data of the tablet)
(Tablet)
1. Activate developer settings (go to Settings->About Tablet->Software information, and tap 5 times on build number).
2. Go into developer settings and activate OEM unlocking and USB debugging.
3. Turn off the tablet and turn it back on pressing Power + Vol. Down buttons to enter Device Unlock Mode.
4. Press and hold Vol. Up and in the next menu, press Vol. Up to unlock the bootloader (attention, this will erase all of your data)
5. Run through the setup, but be sure to activate the internet (this will prevent the tablet from relocking).
6. Activate developer settings again, and go into it to check that OEM unlocking is greyed out.
7. Install Magisk
(PC)
8. (No SD) Copy the AP file to the Tablet.
(Tablet)
9. Go into Magisk, press Install->Patch a file->Recovery mode (on)->Select file (The AP file).
10. Copy the patched file back into your computer.
11. Shut down the tablet.
12. Press Vol. Up + Vol. Down and connect the tablet to your computer with a USB to enter download mode.
(PC)
13. Open Odin, it should show that your device is connected.
14. Go to the settings tab and uncheck the Auto-Reboot option.
15. Flash all the files of the latest firmware, using CSC (not HOME_CSC) but substituting the AP file with the patched one. (With the WiFi version, you might not have a CP file, don't worry)
CRITICAL STEP (if not followed correctly, may lead to bootloop)
(Tablet)
16. Once the flashing is complete, press Vol. Down + Power during 7 seconds to restart the tablet. As soon as the screen blacks out, swap to Vol. Up + Power (and keep pressing even though it asks to press power) to enter the recovery.
17. In the recovery, navigate to Wipe data/factory reset with the volume buttons and press power button to select. Confirm and reboot.
18. While rebooting, you need to press Vol. Up + Power during 3 seconds (Until the press power to continue appears). This is due to Magisk being installed in the recovery partition.
19. Run through the setup again, but this time you need to login into your google account to enter the Play Store.
20. You should have the Magisk app installed. Open it and it will configure itself.
21. When it reboots, press again Vol. Up + Power for 3 sec.
22. Download the Official TWRP app.
(PC)
23. (No SD) Copy the latest TWRP image previously downloaded into the tablet.
(Tablet)
24. Go into the TWRP app and give it root permissions.
25. Enter TWRP flash and select the latest TWRP img
26. Go into the reboot menu and select reboot recovery.
27. The phone will reboot into TWRP.
28. Tick don't show this message again and slide to allow modifications.
29. Wipe -> Wipe data, Cache and Dalvik and Format data.
30. Reboot -> Recovery.
31. (SD) Flash Disable_DM-Verity zip, and then flash Magisk zip.
32. (No SD) enter the advanced menu and open adb sideload. Connect to the PC, open Minimal adb and fastboot and adb sideload the zip files.
33. Reboot system
Congrats, you have a rooted Samsung Galaxy tab S6 with TWRP installed!
FAQ:
1) Ok, I f* up, I am now stuck in the Samsung logo, what do I do?
Press Power and Vol. Down for 7 seconds, this will auto reboot your tablet. Then, as soon as the screen goes off, try to press Vol. Down + Vol. Up and connect through USB to the PC. With some luck, you manage to get into download mode. If you don't, repeat.
Flash the files with the Magisk modified AP, reboot into recovery and factory reset (follow the next instructions if you want to install TWRP), or else flash the stock rom.
2) I am seeing some screens with some warning messages, is that Ok?
Yes, it is normal, Samsung does that to scare people off from installing modifications on their devices. Can I take them off? Yes, but it is not a simple process. If you really want to, follow this guide, but adapting to the device (https://forum.xda-developers.com/t/...sage-on-samsung-a30-after-root-device.3954589). Another important thing is, when you want to enter recovery, you need to keep pressing Vol. Up + Power, even when the tablet displays the message that asks to press the power button.
3) Don't know... You ask
Works perfectly, thank you!
I have a question: to decrypt the internal memory which files can I flash?
