Hello Dr Ketan,

At the next update, the option to see the internal storage memory as an external micro sd will be such as available, it only needs that for your rom to be almost perfect.

Not able to turn camera shutter sound off with csc features. I have tried all 3 options and rebooted each time. I am on T05.

Also, I keep getting notices that there is an update for the rom, but there isnt?

I an confused why it says t04 I thought I had flashed t05, I was wrong. Can I dirty flash t05?
You are on T04
As suggested you haven't removed magisk module before dirty installing T05
In case of later, remove ROM module and reboot should fix

I flashed it and did a factory reset. When I apply essential fix, it gets stuck. Sticks at goodlock install then after reboot and next try it gets past that and stuck at yasnac install then closed now I can't reopen it

Update: it installed and is now up and running, thank you

I have bought S21 and S22 but never convince to make thse device primary because of lacking of SD and till now I was using N20 as primary device. (S21 was pure S series device so there was no question to make it primary as being fan of note series, Indeed donated by S21 users to add ROM support)
Now with S23U I convince myself using it primary as My area just started 5G, We have to accept Ext SD is past and needs to accept "Cloud" service for Backup. I am using GDrive now as you can use same way SD card drive letter in MyFiles OR Root Explorer (Both are my favorite file managers) as separate Drive letter.
Still Hoping some day Samsung add extra external SSD drive to replace Ext SD cards
Also Using Samsung USB OTG for occassional Full Backup and really have nice transfer speed, Using FolderSync is icing on the cake.

    PS : This is a fully customized ROM and for end users only, ROM or any part of ROM not allowed to redistribute,modify or to use as base to prepare new ROM.
    Care to share your battery efficiency tips please?

    debloat all apps that are not needed
    disable all apps that cannot be debloated and are not needed
    limit background processes for all apps you think are needed, either:

    - via the app's settings in Android
    - via the battery settings in Android (there are more options, e.g. disable the background processes completely)

    install magisk module "universal-gms-doze" to limit the background processes of google-play-service
    set power mode of phone to "light" (battery and device maintenance -> battery -> advanced battery settings)
    make sure in the developersettings that mobile data is turned off, if connected to wifi
    assign a static IP in the wifi settings, if possible
    disable "switch to better WLANs" in the advanced wifi settings
    activate "WLAN energy saving mode" in the advanced wifi settings
    disable "Automatically connect to Hotspot 2.0 WLANs" in the advanced wifi settings
    in connections -> mobile networks disable 5g ("connect LTE/3g/2g automatically")


    Create profiles to e.g.:

    - With DND enabled (10pm - 7am for me) and screen off, enable airplane mode and reactivate when screen is turned back on.
    - With VoWifi available turn on airplane mode/wifi and turn off airplane mode again when wifi is not connected

    I may have forgotten one or two things, but these are the most important steps (for me)
    It depends of course on your use of the phone, whether the steps are useful

    Only for my understanding.
    If I am on your latest ROM version T07, it is not necessary to store and keep your older ROM versions (T06 etc.), because there is no way to to downgrade the ROM/Firmware except they have same bootloader? ...and propably this behavior won't change in the future?
    You should able to downgrade as far as bootloader revision remain same. For example base of T07 is S918BXXS1AWD1
    Here 9th digit is binary revision (1 in above value)
    You can downgrade to other version as far as this 9th digit version remain same
    Currently it's under test, wait for changelog post to update status.

    XDA devDB Information

    S918 I Dr.Ketan ROM , ROM for the Samsung Galaxy S23 Ultra


    ROM OS Version: Android 13
    ROM Kernel: Stock (pre-rooted). Source code (samsung) here
    ROM Firmware Required: Stock Samsung specified version

    Version Information

    Created 2023-02-09
    Installation, Important Infos & Download

    : State of the art Installation procedure.

    • Only needed is supported device + Unlocked bootloader.
    • No needs to have device rooted/Installed TWRP/update device to specific base
    Detailed installation guide separately available in download area along with ROM files.


    Before you root your device you must be aware that

    • This will void warranty.
    • As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help.
    • There are many features stop working when you unlock bootloader other than S pay/Pass like Samsung Health, Secure Folder, Galaxy Watch pairing issue, Issue connecting old gear watch (S3 or earlier), Google Pay etc but ROM is patched for all these mentioned features. Still you may trouble using some bank apps and these may fixed by adding these apps to Magisk Hide
    • There may be some knox features there which you may not able to use but I can't list those as I never used. Just Google It
    • Patched featurs are working today when writing this, No idea if it may stop working next moment/tomorrow or later
    • Also to note, once you root, you can't go back to "pre-rooted" state completely. It is one way!
    • OTA won't work on rooted device.
    • ROOT with caution.
    • On unlocking bootloader you will have warning screen while device boot and as of now no workaround to hide. Though it can be removed with re flashing stock rom + re locking bootloader
    • You can unroot & Relock bootloader after flashing stock firmware, but still your warranty flag remain 0x1 and most of countries it still voids warranty. Also after unrooting & relocking bootloader, some knox features never work again.
    ROM Tool permission : Files & media - To save and read files, Calendar - Tool needs some time monitoring to avoid using RT immediately after reboot. Special access for accessibility service - Since Android 12 it requires for QS panel custom Toggl e.g. Reboot to recovery
