[Samsung Galaxy S7 Edge Questions and Answers] Rapidfayaround:
1. Download a U8 firmware for your device which is SM-G935F. You can download it in sammobile.com , updato.com or samfw.com

2. After the download is completed, you need to extract the downloaded rom (I recommend using apps like 7zip or Winrar)

7-zip: https://www.7-zip.org/download.html

3. After you extract the file, you will be greeted with files saying

AP_XXXXXXXXXXX

BL_XXXXXXXXXXX

CP_XXXXXXXXXXX

CSC_XXXXXXXXXX

Home_CSC_XXXXXXXXX

4. Extract the AP_XXXXXXXXX with 7-zip or Winrar

5. In my case, 3 files and 1 folder were extracted which were

system.img.lz4

boot.img.lz4

recovery.img.lz4

meta-data (This is a folder)

Note: In your case, there might be different amount of files with different extensions

6. Copy "boot.img.lz4" to another folder (lets call the folder Hello for now) and rename the boot.img.lz4 to "recovery.img.lz4"

7. Make a backup of the original "recovery.img.lz4" and "boot.img.lz4" and "meta-data" and delete those files/folders

8. Copy the "recovery.img.lz4" file from Hello to your folder which contains system.img.lz4

9. Now, your folder should only contain system.img.lz4 and recovery.img.lz4 (renamed boot.img.lz4)

10. Download the Auto Tar folder

https://www.mediafire.com/file/ah20h...s.com.rar/file

11. Extract the autotar file using 7-zip or winrar

12. Copy all the content inside the autotar file and paste it to your folder containing system.img.lz4 & recovery.img.lz4 (renamed boot.img.lz4)

13. Open the Autotar application

14. Select system.lz4.img and recovery.img.lz4

15. Press on make .md5 & type the name on the box beside select files

Note: There should not be any special characters in the name, I recommend not using any spaces, numbers, capital letters or special characters like !@#

16. Then, wait until it says done, usually took us around 15 Minutes

17. Open Odin, if you dont have odin download it

18. In Ap tab, choose the newly created .md5 file and do the same for CSC, CP & BL

19. Connect your phone to the PC in download mode

20 Then, flash

Note: If the verification fails, rename the newly created .tar.md5 file and remove .md5 from its name, then we will be left with .tar file

21. Set up your phone and before switching off/ restarting or doing anything "Special" enable OEM unlock, or charge your phone if it has less battery, which was the issue in my case

22. Restart your phone and you will be greeted with No Command screen. The first time I saw that again, I got freaked out but dont worry the solution is pretty simple due to the fact we dont have FRP lock anymore

23. Go to download mode and flash UNMODIFIED CP, CSC, AP & BL

24. You will get the no command screen again, no worries though, go to TWRPP websiet and download TWRP for your device

https://twrp.me/

25. Enter download mode and flash the recovery through the AP tab

26. Download this

https://zackptg5.com/downloads/Disab...03.04.2020.zip

27. You will be rebooted to the TWRP screen. And by the way, ALLOW SYSTEM MODIFICATIONS

28. Connect your phone to the PC and transfer the previously downloaded Dm verity file and copy it to your phone

29. Go to Install in your TWRP screen and locate the file and install it

30. Clear Dalvik Cache and reboot

Edit: Alternatively, In the last steps, you can flash turbo luke's twrp instead of official twrp, then select format option in twrp wipe, then flash no-verity-force-encrypt

Then flash magisk from here : https://github.com/topjohnwu/Magisk/releases/tag/v20.4

In all of doing this, don't swipe for system modifications in twrp, it is basically useless and obsolete now, as magisk does everything without modifying system.

Ofcourse, this only applies to stock rooted rom and stock based debloated custom roms (which have non-modified system)

Edit 2: This a copy pasta
