Really S23U battery is amazing. Today there was quite high usage and nearly 5 Hrs SOT and still half battery juice spared.

Good Night everyone.
Thank you guys for reporting and supporting ROM.

Hello, I'm facing an issue where the Galaxy S23 Ultra is not able to start up properly. I'm also not able to get into Download Mode nor into the Recovery Mode again.

My Galaxy S23 Ultra is not really in a boot loop. It's more that the screen is black and it's booting up occasionally/randomly when playing around. Having the cable connected to the PC and pressing [Vol Down] + [Power] to get into Download Mode or [Vol Up] + [Power] to get into the Recovery Mode is not possible anymore as the smartphone is not reacting and then the screen gets black again.

I never faced such an issue and was always able to solve issues but this time I'm quite perplexed. I would very much appreciate any tips or ideas what could be done in such a case.

It actually happened when I installed System-RW T05 and accidently did a factory reset.
At this point my colleague (who owns the smartphone) wanted to get his apps data back. Therefore he did a restore with TWRP but wasn't able to login with the screen lock password even he used the correct password. Then he took an old Backup and restored also the boot partition. At this point the smartphone wasn't able to boot up or to get into download or recovery mode again.

    @dr.ketan have a question. I was planning to flash this ROM. Currently I am on Samsung official room, rooted with magisk. Just a info i wanted, is that if i plan to dirty flash this rom using the tool that you have provided for the same, would it be okay? (i know it might face issues, but going through the formatting process is a little tough for me due to my work schedule)

    Can you please advise?

    Edit:
    I read the thread where others have also said its possible, but done remember seeing anyone stating they followed the process from official rom to custom rom. Have only seen it for the update part.
    • Tool isn't available separately, that means you can use only if you are on Dr.Ketan ROM and wanted to update to Dr.Ketan ROM.
    • Dirty flash will never work while you moving ROM from encrypted to decrypted data or vise a versa
    PS : More detail Installation guide available in ROM download area, refer it before flashing 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
    or
    - 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")


    Tasker:

    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

    I want to make a fresh and clean installation of t07 rom.
    Actulay I'm under t06 version.
    How can i do ?

    does i need to:
    - install TWRP,
    - clear data user, and wipe full data

    before install the t07 version ?
    Straightway Flash T07 (Use CSC file from stock firmware of your region if it is not from OXM grousp)
    Reboot to TWRP (It should auto reboot to TWRP after flashing ROM, if no, do manually) → Factory Reset/Format data as per your liking) → Reboot to System → Install Magisk apk → Open and complete additional setup → Reboot → Apply ROM Tool Essential Fix

    PS : You can find all details in Installation Guide.

    Received my s23 ultra last Thursday and flashed it directly with DrKetan T07. The installation and setup of the rom was smooth and the rom works perfectly! Even my banking apps work without me having to freeze magisk. Anyway i am very happy with the phone/rom

    Installation, Important Infos & Download


    Installation
    : 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.

    WARNING

    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
