Hello. I am on Dr. Ketan's Android 13 beta with Tweaks Pro on SM-S908N. I am getting data connection loss. I need to restart the device in order to get data connection working again. The issue is occurring randomly. I am still trying to figure it out what is causing it. When it happens I noticed that the APN settings in connection are for BSNL India. And APN of my current Provider in Canada is missing. Anyone know how to fix this?

If you have enabled Goodlock native support in Tweaks, disable it and reboot

Root files uploaded to download area for today's Beta
- S908E Beta3 (VJ2)
- S908B Beta4 (VJ2)

Installation :

  • Unlock bootloader
  • Download from XDA ROM download area (link below) and extract root files to get *tar.md5 file
  • Turn off Auto reboot option in Odin
  • Flash extracted *.tar.md5 with Odin AP slot
  • When file get flashed (You will see PASS), Keep holding Vol Down + Power (With device connected to PC). Once device reboot, immediately release vol down button and keep holding power + vol up (For a moment you needs to release and hold again poswer button when asked), this will reboot device to recovery - select to factory reset
  • Reeboot to system. Update Magisk from stub OR Install Magisk 25.2 apk
Download : DrKetanROM.com

TWRP : (Only for expert)
Root file doesn't have TWRP included. If you want to test, flash it separately. No needs to flash patched vbmeta as Root files already have included it. TWRP may work but Kernel may or may not work so don't run 'multidisabler' else device may not boot. Still if you want to try, make backup of boot and super partition before applying 'multidisabler' If device doesn't boot, restore both and format data.

PS : You have to make backup of boot & super on USB storage as before multidisabler, data partition won't work

Perfect thank you! Is AVF9 bootloader good to use or update to latest firmware? & Is sideloading the updates safe to dirty flash over AVF9 rom?
You must be on firmware for which beta one is released. For S908E it is vg6
There is oneui 5.0 beta thread there, where you get info for other device.

this is quite cumbersome ...
first for us who have vh9 we have to revert to vh6 then install beta 1 then 2 then 3 then 4. i know 1 to 4 is incremental and samsung isnt releasing a full rom build file but increments.
i wonder when samsung will get their act together and call this done ... lots of OEMs have released A13 official.

As said earlier I am not going to update A12 base now. A13 is around the corner and my focus in only on A13.

Hello there!

INFO:
Device: S22 Ultra (SM-S908N)
OS: Android 12
TweaksPro S22 Version: 5.0.3
Magisk Version: 25.2

I've enabled E-Sim option in TweaksPro - but the option "Add Mobile Plan" is not appearing in "Sim Card Manager" menu.
Inside Magisk Manager - in the modules section - a module called "DrKetan_ROM_S22-v10" is causing a bootloop if I enable it and reboot the device.

Please advise.

    Regarding full ROM (for S908B/E)

    What I am planning is to make Odin flashable ROM from next version. Now a days on newer device you needs PC & Odin to flash bootloader so making ROM with TWRP flashable zip still you needs PC, Instead if I make Odin flashable ROM then it will be much easier. Even you no more needed to have same firmware installed.
    Installation will be swift like
    • Flash provided files with Odin with respective slot
    • Wipe/Format will be optional if you are already on my ROM. (must in case you are on stock/encrypted data)
    What you think?

    T04 Full ROM System-RW is online now for S908E (S908B will be released once new firmware available)

    IMPORTANT
    : New ROM is having complete different installation procedure, Must read Installation guide available in download area.
    Reports & Reviews will be highly appreciated!

    Thanks for using Dr.Ketan ROM.

    Is it possible to use BWA2 AP file from another country and (AP BL HOME_CSC) from another country to update S906E? Because S906E doesnt have the latest BWA2 update in IND yet
    Yes, choose any OXM group of csc (csc file name have OXM text.)
    But i do want to know what else it provides ? other than safety net, good lock, fox mm and lsexposed.
    Thats it
    Got a quick question: Since the upgrade to T04 I have been unable to send or receive MMS messages. I don't think it's ROM-related but, every other fix I have attempted had not been successful.
    Wondering if reflashing ROM might help?
    Have you check access point? First try settings - connection - mobile network - access point - 3 dot and reset
    If that doesn work, look on device that have working and manually edit same
    If I flash the home, I don't have to do anything new, right?
    Read wipes data policy in installation guide
    Hello, what is the reason for not executing secret codes, for example battery test *#0228# or code *#*#4636#*#*
    Most of short codes are obsolete
    Try working code and see if that works like *#1234#
    If that working then no issue on device else flash Home_csc file from your regional firmware

    Update for S908B
    T04 full System-RW ROM for S908B (jan 2023 patch WA2) is ready and under testing now.

    Installation and Download & Notes


    Important :


    - 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. (hope in future we can get it working on tripped knox device)
    - OTA won't work once you root device.
    - 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

    Installation :

    For Magisk module ROM Read ChangeLog post for Installation instructions (link on post #3)

    Proposed ROM development now onwards :

    Looking to poll results, it seems most users wants Full system-rw ROM including Mods. So finally found a way so users with any choices won't get disappointed.

    • To make a Full ROM + Mods (No Magisk module requires). This will only for S908B & S908E - This will be for users with choice 1
    • Above said ROM will have option in ROM Tool to remove customization, with this you can remove all customization and retain with pure stock experience. Before removing customization, still you can apply essential fix so it will keep all important systemless fix like SafetyNet/GPay etc. - This will be for users with choice 2
    • Magisk Model development will remain continue for all other variants including S908B/E

    I am Testing Full ROM including mods now on S908E, soon it will be public.
    Thank you for trust & support for ROM!

    PS : Full ROM is under testing now!
