First, Thx!!
It works!!!!!!!!
I appreciate your time and answers.

But... my problem is that I want this device to function as a phone and not as a tablet, because in google assistant there are options that are working only with phones and not tablets.

Do you think I have a way to do it??
maybe another GSI ROM?
Is there a way to make the device think that it is a phone and not a tablet?

thx in advance.

you should to find GSI which had offline charging function. Due to effect from vbmeta warning . But the important thing you have fastboot function to use with your Samsung device, (Fastboot CMDs can work even if the OS is not booted.or bootloader mode)
:coffee::coffee: good luck

Thx.
1. How can I know if a GSI had or not the offline charging function?
2. Do you know one GSI maybe?
3. What is it this function? You mean the wireless charging?
4. If I will flash not a good ROM, will it permanently brick the device? Or I can always go back to the stock ROM?

You are the master!
Thx!

Try to turn off your tab, then insert cable to charge, it will show vbmeta warranty only and struck not show charging level power, you must press and hold (power + vol down) to escape from
It charging but not informed I though. 😂

I do not understand 🤭🤭

Can you maybe send me a link to read what is it the offline charging function and what does it have to do the problem that I am facing?
Or if you know such a GSI ROM?
Thx!!

What a shame. It's like LineageOS, it supports exFAT for things like OTG pendrives but not for the device's microSD slot. That one has to have another filesystem, otherwise the OS will bug you to format it and it still won't work after doing so.

A filesystem for a storage device. Examples of filesystems: FAT32, NTFS, EXT4, exFAT, among others.

    copy output " super.img" to uses with Ubuntu at /home/username/

    >>>>>>>>>>>>≥>>>>>>>>>>>>>>>>>>>>>>

    For Linux:​

    ✓ launch Ubuntu terminal( console) from Start menu

    2.1) Option We can uses LZ4 from linux, process same as (Step 1-2 for wins)

    Ubuntu
    you can install LZ4 from Ubuntu Console with

    Code: 
    sudo apt update

sudo apt-get -y install lz4

    sudo lz4 -d super.img.lz4  super.img

    Screenshot_20220917_234111_Gallery.jpg
    2.4)COMPARE with using "lz4" between Ubuntu and Windows

    Screenshot_20220917_235214_Gallery.jpg

    ​

    CONCLUSION of Beginning step.​

    WE CAN GETS " SUPER.IMG" FROM TWO WAYS , WINDOWS OR LINUX.
    ( windows from step 1-2 ) or. ( Linux from step 2.1 -2.3)


    ***We will use 'super.img' to begin our modification.​
    ​

    ✓ unpacking super.img​

    3.) Turn sparse format To RAW​

    Ubuntu

    **First of all the super.img file might be in sparse format so we need to make it raw image. By Using "SIMG2IMG"

    Code: 
    sudo apt-get update
sudo apt-get install simg2img

    I'm
    ok
    Code: 
    sudo  apt-get install img2simg

    After install execute this command.

    Code: 
    sudo  simg2img super.img  super.raw

    Screenshot_20220917_235842_Gallery.jpg


    ✓Extract subpartition out from "SUPER.RAW"​

    4) Tool for extract partition. ( very important tool for show "group schema" which used to specific parameter option for lpmake.)

    4.1) Download imjtool
    http://newandroidbook.com/tools/imjtool.tgz
    or download from attach file belows this tutorial (imjtool.zip)

    4.2) extract "imjtool" from archive imjtool.tgz to /home/username/

    *note for short i renamed it to 'imjtool'

    4.3) then give it permission with command

    Code: 
    chmod +x imjtool

    imjtool.PNG


    5) Extract sub partition within our "SUPER.RAW"

    By execute this command
    Code: 
    ./imjtool super.raw extract

    It will extract sub-partitions (4 img files ) in the folder "/home/user/extracted"
    - system.img
    - vendor.img
    - product.img
    - odm.img

    Screenshot_20220918_002304_Gallery.jpg

    ✓ Modify Stock "system.img" by Changes with GSI-"system.img"​

    6) Choose your favorite GSI. ( Recommend PHH Treble- GSI )
    Download from :-
    https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list

    6.1) Extract Downloaded archive & Replace "system.img" with your GSI img
    (rename it to system.img over-written the old file.)

    Screenshot_20220918_002502_Gallery.jpg

    6.2 )
    Move all img files (6.1)
    from /home/username/extracted folder into /home/username/


    7.) Get each partitions file size.

    we can do it by:

    Code: 
    stat -c '%n %s' IMG_FILE.img

    :- do it for all partitions files.

    7.1
    Code: 
    stat -c '%n %s' system.img
    Exam output---system.img 308 951 4496

    7.2
    Code: 
    stat -c '%n %s' vendor.img
    Exam ouputt----vendor.img 718 503 936

    7.3
    Code: 
    stat -c '%n %s' product.img
    Exam output----product.img 118 811 8528

    7.4
    Code: 
    stat -c '%n %s' odm.img
    Exam output----odm.img 434 9952

    7.5 ***size of the "original super.raw"
    Code: 
    stat -c '%n %s' super.raw
    Exam output----super.raw 609 432 3712

    Screenshot_20220918_002752_Gallery.jpg

    ✓ Repacked modified sub-partition back​

    8) Repacked new super.img.

    8.1 fill in "img partition size" formular (parameter) to your prepared command below

    explanation:
    Screenshot_20220918_074316_Gallery.jpg

    explanation:
    Prepared command "LPMAKE" parameter
    sudo ./otatools/bin/lpmake --metadata-size 65536 \

    --partition vendor:readonly:VENDOR_PARTITION_SIZE:main \
    --image vendor=./vendor.img \
    --sparse \
    --output ./super_new.img

    Note:
    Replace
    ORIGINAL_SUPER_IMG_SIZE,
    SUM_OF_ALL_PARTITIONS_SIZES
    ODM_PARTITION_SIZE,
    PRODUCT_PARTITION_SIZE,
    SYSTEM_PARTITION_SIZE,
    VENDOR_PARTITION_SIZE

    with the values you obtained in step 7.

    after flashing patched Magisk file can I just stop here without putting the TWRP and use tablet as its with root? what are the advantages of having the twrp since there is no ROM and encryption still going to be there?
    Click to expand...
    Click to collapse
    1. Root ( by patch boot.img with magisk ) is not depended on TWRP.

    2. We can uses Fastboot of TWRP for flashing GSI (system) because Sam devices have not using Fastboot mode.

    3. if you don't uses fastboot or twrp for flashing tools , the only thing left is odin.

    Go to customize your sam device with odin if you want. :coffee:

    I never used Bluetooth with Sony. Used only wired.
    Try to setup GSI here
    -Samsung features
    Enable stereo audio mode
    Enable extra sensor    s

    -Misc features
    Use alternate way to detect headsets
    Disable audio effects

    I am doing all the steps, but it stays stuck on the TWRP (it is booting again and again to TWRP).

    Is there any other step to do?

    I am trying to install GSI PE for sm-t225n, which pixel experience version should I use?
