This An odin tar file I have created to flash along with stock odin firmware to automatically install TWRP recovery along with Disable VBMETA image. The tar file will also automatically install magislk root along with remove force encryption and patch bluetooth library file. It will also patch safetynet. No flashing of zips is required

Be prepared to have your data wiped. The process tries to determine if you do or do not need to have data wipe but as a precaution just assume your data will be wiped. Especially if using U1 or W firmware

Install Instructions For Newly Unlocked Devices

You must be OEM Unlocked Bootloader
1. On Initial unlock of phone you must through setup and be signed into your google account.

2. Reboot phone too download mode and make sure KG STATUS=CHECKING (see pic) and not PRENORMAL. If PRENORMAL then do step 1 again
View attachment 5217631

3. Use patched 3.14 odin and load file USERDATA_SLOT_G98*U_**.tar.md5 you must choose one of the FORCE_WIPE files and load in the USERSDATA slot of odin and flash file

4. Phone will reboot to TWRP and remove encryption which will wipe phone. Phone will reboot back too TWRP to finish install then reboot to setup



Install Instructions For Updating Firmware On Phone Already Unlocked

1. Reboot phone too download mode and make sure KG STATUS=CHECKING. If not see above

2. Use patched 3.14 odin and load stock firmware in appropriate slots use regular CSC file in the CSC slot and load file one of the USERDATA_SLOT_G98*U_**.tar.md5 in the USERSDATA slot of odin and flash firmware. Do not use the User Data file that comes with firmware.

3. Phone will reboot to TWRP and check for encryption and remove if needed which will wipe phone. If phone is not encrypted data will not be wiped. Phone will reboot back too TWRP to finish install then reboot to setup if data was wiped or reboot normally if it was not



Install Instructions If Updating Images With TWRP

1. When done flashing images in TWRP Reboot phone too download mode and make sure KG STATUS=CHECKING. If not see above.

2. Use patched 3.14 odin and load file USERDATA_AIO_G98*_NO_WIPE_NO_BL.tar.md5 in the USERSDATA slot of odin and flash file.

3. Phone will reboot to TWRP and check for encryption and remove if needed which will wipe phone. If phone is not encrypted data will not be wiped. Phone will reboot back too TWRP to finish install then reboot to setup if data was wiped or reboot normally if it was not.

4. Alternatively to using USERDATA_AIO_G98*_NO_WIPE_NO_BL.tar.md5 in odin you can use AIO_Magisk_22_S20_Series.zip found in post 2

This works great! I flashed the entire U1 DUB7 update with the force wipe with BL files in the USERDATA slot. Everything went well.

Both files that say contain bootloader from UI 3.0 and that I'll keep my unlock token. kg status was checking as well.
Sorry I had no clue there was an sm-g981v mode. Just don’t flash the bl file of your stock firmware and you will be fine using my userdata without bl files

Does this work on s20 plus g9860?
If not...can you make a file for SM-G9860 TGY.

So, if I have the S20+ (US Cellular) and want to try the 3.1 firmware:

1.) Download the firmware
2.) Put your file for it into user data field in Odin
3.) Put in AP, CSC (home or whatever to not overwrite my USC one I think) and the rest EXCEPT for the bootloader into Odin
4.) Flash as usual and then everything should work. I'll keep my unlock and be able to use the 3.1 firmware?

I did it that way, used the BL included file and flashed all the stock files, after the full wipe everything that I needed was included. Worked great, on UI 3.1 rn

    fwiw, i made a couple of AIO tars for my S20+ 5G (SM-G986B)

    file 1: AIO_SM-G986B.tar
    - installs TWRP
    - boots to TWRP immediately after ODIN completes (leave Auto Reboot enabled) - avoiding the vulcan death grip button push nonsense
    - formats data
    - installs decrypter and stock recovery replacement disabler (by @serajr from here - kindly created when the long running multidisabler stopped working as Samsung changed a path)
    - installs TWRP Bootlogo Patcher from here to remove the ugly warning on boot
    - installs Bluetooth Patcher (TWRP method) from here
    - wipes /cache
    - reboots to system and setup

    file 2: AIO_SM-G986B (TWRP & Decrypt ONLY).tar
    - installs TWRP
    - boots to TWRP immediately after ODIN completes (leave Auto Reboot enabled) - avoiding the vulcan death grip button push nonsense
    - formats data
    - installs decrypter and stock recovery replacement disabler (by @serajr from here - kindly created when the long running multidisabler stopped working as Samsung changed a path)
    - wipes /cache
    - reboots to system and setup

    flash AIO in userdata alongside ROM files

    NOTE: device will reboot several times, do not interrupt, let finish and boot into system and setup. During TWRP session you will see red text (errors), this is for mount points that dont exist due to the formatting of data and are normal in this context...you will see the zips being processed after the errors

    NOTE 2: the original AIO files also installed Magisk and patched SafetyNet, i chose to, as Magisk is updated frequently and SafetyNet methods can change monthly, remove them from my version, i prefer to flash Magisk etc manually. This makes less maintenance recreating the tar files

    How i created the tar files (using the full 1st version as example):

    Contents updated from the SM-G986U/U1/W- Model zip from OP i used as a template:

    extract zip to a folder

    download latest TWRP

    twrp-3.6.2_11-0-y2s.im (latest at time of writing for my device)

    twrp-3.6.2_11-0-y2s renamed to recovery.img

    compress with lz4:

    Code:
    lz4 -B6 --content-size recovery.img recovery.img.lz4

    recovery.img.lz4 copied to extracted folder, overwriting original (outdated) recovery

    cache.lz4 copied to folder containing lz4, imgextractor and make_ext4fs binaries (my working files for Windows attached)

    cache.img.lz4 decompress:

    Code:
    lz4.exe -d cache.img.lz4

    image extract:

    Code:
    ImgExtractor.exe cache.img

    gives you a folder: cache_

    edit cache_/recovery/openrecoveryscript and add/remove any lines to install zip files

    add/remove/edit/update any zip files to cache_/recovery/ folder you wish to be flashed

    compress cache_ folder:

    Code:
    make_ext4fs.exe -s -l 12M -a cache cache.img cache_/
    
    lz4 -B6 --content-size cache.img cache.img.lz4

    move cache.img.lz4 to original extracted folder and overwrite

    finally select the 4 files and create a new tar - on windows this is easiest done with 7-Zip

    Code:
    lz4 -B6 --content-size recovery.img recovery.img.lz4

    recovery.img.lz4 copied to extracted folder, overwriting original (outdated) recovery

    cache.lz4 copied to folder containing lz4, imgextractor and make_ext4fs binaries (my working files for Windows attached)

    cache.img.lz4 decompress:

    Code:
    lz4.exe -d cache.img.lz4

    image extract:

    Code:
    ImgExtractor.exe cache.img

    gives you a folder: cache_

    edit cache_/recovery/openrecoveryscript and add/remove any lines to install zip files

    add/remove/edit/update any zip files to cache_/recovery/ folder you wish to be flashed

    compress cache_ folder:

    Code:
    make_ext4fs.exe -s -l 12M -a cache cache.img cache_/
    
    lz4 -B6 --content-size cache.img cache.img.lz4

    move cache.img.lz4 to original extracted folder and overwrite

    finally select the 4 files and create a new tar - on windows this is easiest done with 7-Zip
