Hello guys :)

I've rooted my S22 Ultra. Root works but Samsung Health doesn't want to open.
The first time I open it, I have seen "Access denied...".

Can you help me please ?
Follow the steps below to remove the S-Health block.

  1. Download a root file explorer (such as Root Explorer, Root Browser or ES File Explorer).
  2. Open the root file explorer and go to the /system folder.
  3. Open the file named build.prop in text editor
  4. In the build.prop file look for ro.config.tima=1
  5. Change this line to ro.config.tima=0, simply changing the 1 to a 0
  6. Reboor phone
  7. Run the S-Health app

I got my S22U 1TB Exynos today and unfortunately have not been able to unlock the bootloader.
OEM option wasn't there so I followed the steps for previous sammys (changing the date, check for updates, restart and option should be there).

If I let the phone boot, OEM unlock will again disappear.
If I am fast enough and enter developer settings before the phone finished booting up, the switch appears and, to my surprising, says it is already on (despite the bootloader telling me lock is still on).
Disabling and reenabling it just leads to the button being in an unrecoverable state, "trying" to switch it to on.
If I leave developer settings and reenter it again afterwards, the switch is gone again.

Unless someone has an Idea how to deal with that, it seem I need to wait the 7 days to get it permanent, like I had to in the past.

EDIT:
I finally figured out how to avoid that behaviour: if you do not have added a sim card yet and just trying to root with just wifi on, you'll waste your time. Just put a sim card inside and it suddenly works.
Hi!

Ive been facing the same issue.
The OEM unlock just wont show up no matter how many times I keep changing the date, press update manually!
It came up once and it just wont show up again.
P.S : I did put the simcard and try. still no luck as of yet.

Any other solution to this would be much appreciated.

ROY.

In India oem unlock option available by default. I never had issue on Indian device in past too. By the way are you using it outside India?
I'm using it in India itself sir. Still no luck. Have changed the date and turned off automatic update rebooted and checked million times. Still no luck.

It showed up once and disappeared again.

    This is just not true. Does not work like that. Getting in download mode is different;
    You have to press Vol UP+Down and then plug in the USB WHILE KEEPING VOL UP+DOWN PRESSED. That is how you get into Download mode. I keep getting users asking me why it doesn't work. This is why. You really need to correct this..
    thanks, I meant to write like that but I seem to have made a few mistakes,I will correct them, thank you very much

    Code:
    Your warranty is now void.
    If you root your device, Your KNOX status will be tripped.
    You can still pass the safety net after you root if you follow the instructions.
    Sorry for USA models, you can't root unless you can unlock your bootloader
    You will lose ALL your data if you unlock your bootloader. Do back up your data.
    I am not responsible for bricked devices, or dead SD cards although it is not possible
    Please do some research if you have any concerns about doing this to your device

    How to flash official firmware? (not the root and unlock bootloader part!)

    You will need:

    A Galaxy S22 Ultra and common sense

    Samsung Odin (the flashing tool of the official firmware)

    https://dl2018.sammobile.com/Odin3-v3.14.1.zip

    You need to extract the zip file and you are going to use the file Odin3_v3.14.1.exe inside the folder.

    Samsung Android USB Driver for Windows


    Double-click and install the exe file.

    Optional: If you just want to change CSC, /efi/imei/mps_code.dat is where you can edit after rooting the phone
    Replace the CSC you would like to be in the file

    If you like to download the firmware of your carrier, follow the instructions bellow


    Download the platform you want to download to. (Windows)

    You need to extract the zip and double-click open the file Bifrost.exe inside the folder.

    You need to fill in the Model, and Region, press the Check for Updates button and the Download button.

    How to find the Model: on your phone → Settings → About Phone → The third row says the Model number and you need to remove the part with the part of /xx, for example, SM-S908B/DS and you only need to type SM-S908B

    How to find the Region: You can check the Region at this link https://samfrew.com/model/SM-S908B/

    You need to find find a three-letter word depending on your carrier and country and type it in Bifrost, for example, EVR

    Press the Check for Update button and download it with the Download button.

    Put it to a place you can easily find, ie. Desktop.

    After downloading it, find the file SM-xxxxx_x_xxxxxxxx_xxx.zip.enc4 on the place you put it and change the document format from .enc4 to .zip. Then, double-click and extract the file.

    Open Odin3_v3.14.1.exe and turn off your phone. Connect a side of your USB to your PC/Laptop, and keep pressing volume up and down together until you go to Download Mode. Put another side of the USB into your phone. When you arrive at Download Mode press volume up. Go back to Odin3_v3.14.1.exe:

    -Click on BL and select BL_xxxxxxxxxx.tar.md5

    -Click on AP and select AP_xxxxxxxxxxx.tar.md5

    -Click on CP and select CP_xxxxxxxxxx.tar.md5

    -Click on CSC and select CSC_OMC_xxxxxxxxxx.tar.md5

    Optional: add PIT file if you have to repartition.

    Press Start to flash the firmware, after that is done, your device will automatically reboot to the system.

    How to unlock the bootloader?

    Go to your phone → Settings → About Phone → Software information → Press Build number 6 times until you see the notice “You’re now a developer”

    Go in Settings → Developer options → enable OEM unlocking

    Power off your phone first. Then, connect a side of your USB to your PC/Laptop, press Vol Up + Down and then plug in the USB while keeping Vol Up+Down pressed.

    When you arrive at Download Mode, long press volume up until you see the black screen. Confirm to unlock the bootloader and you will erase your device.

    How to root your phone?

    After you unlock your bootloader, you set up your phone and ensure you do not sign in to your Google account first. Install Magisk https://github.com/topjohnwu/Magisk/releases/download/v24.1/Magisk-v24.1.apk on your phone. You need to allow the app to install other apps so that you can install the apk.

    Transfer AP_xxxxxxxxxx.tar.md5 in the firmware you download from your PC/Laptop to your phone.
    Open Magisk on your phone and press the install button in the Magisk column. Select 'Select and Patch a File', 'Let's Go and find the AP_xxxxxxxxxx.tar.md5 and select it. You can have a cup of coffee if you like when you waiting for the patching of the file.

    After finishing the patching, transfer the file magisk_patched-24xxx_xxxxx.tar in the Downloads folder back to your PC/Laptop.

    Turn off your phone. Connect a side of your USB to your PC/Laptop, and keep pressing volume up and down together until you go to Download Mode. Put another side of the USB into your phone. When you arrive at Download Mode press volume up. Open Odin3_v3.14.1.exe on your PC/Laptop:

    Click on BL and select BL_xxxxxxxxxx.tar.md5

    -Click on AP and select magisk_patched-24xxx_xxxxx.tar

    -Click on CP and select CP_xxxxxxxxxx.tar.md5

    -Click on CSC and select CSC_OMC_xxxxxxxxxx.tar.md5

    Optional again: add PIT file if you have to repartition

    When it finishes flashing, it will automatically reboot and you can gain root access.

    Optional: If you want to have the safety net passed (most of the banking apps use it), then you need to install the zip
    as a Magisk module in Magisk https://github.com/kdrag0n/safetynet-fix/releases
    How? Go to Magisk → Modules → install from storage and select the zip you downloaded.


    How to update the system without losing roots and data?

    Download the new firmware of the phone and update the Magisk App if it is not up to date. Unzip the firmware you download and transfer the AP file to your phone. Patch your AP file and transfer it back to your PC (in /sdcard/Download)

    Power off the phone and reboot to Download mode


    Open Odin and put the new magisk_patched file in the AP slot, the BL and CP from your new firmware into their respective slots and importantly *HOME_CSC* into the CSC slot.

    Press start and let Odin do its stuff.

    When flashed, do not wipe.

    Press and hold Vol-down and Power
    As soon as the screen appears, let go of all buttons.

    Within moments without any further user intervention your phone will reboot into your updated Magisk rooted mode, data intact.

    It gives me an error when I try to check for updates. It's the EUX version.
    I think you may need to download the file at this link, although it will be slower. Usually, the app always works. Sorry

    Thanks for the guide, @Williamtung .

    However I feel the strong urge to share a much more convenient change on one step of the procedure, which I keep reading over and over, that can be done in a better way:

    Transfer AP_xxxxxxxxxx.tar.md5 in the firmware you download from your PC/Laptop to your phone.
    Open Magisk on your phone and press the install button in the Magisk column. Select 'Select and Patch a File', 'Let's Go' and find the AP_xxxxxxxxxx.tar.md5 and select it. You can have a cup of coffee if you like when you waiting for the patching of the file.

    After finishing the patching, you need to transfer the file magisk_patched-24xxx_xxxxx.tar in the Downloads folder back to your PC/Laptop.

    Manipulating (copying back and forth, Magisk processing it, etc.) not only takes a huge amount of time, but it's also risky to any data transfer failures.

    You can do it in a simpler way, ultra-fast and risk-free (end result is the same)

    1 - Open AP_xxxxxxxxxx.tar.md5 with 7zip (as a .tar file), look for the boot.img.lz4 file, and extract it to the same folder
    2. Compress that boot.img.lz4 file into a TAR file (use 7zip as well). Name the resulting file whatever-you-want.tar
    3. Copy whatever-you-want.tar to your phone
    4. Open Magisk on your phone and press the install button in the Magisk column. Select 'Select and Patch a File', 'Let's Go' and find the whatever-you-want.tar and select it. You don't need the coffee, it will be completed first.
    5. After finishing the patching, you need to transfer the file magisk_patched-24xxx_xxxxx.tar in the Downloads folder back to your PC/Laptop. This TAR file is tiny (because it contains the patched boot.bin file only), but you can flash it with ODIN in exactly the same way as the full one.
    Odin actually scans the input TAR files and flashes each file inside that it recognizes, to the right partition according to the file name (boot.bin > boot partition). It even handles files that are LZ4 compressed (look for those ending on .lz4)

    If you liked the improvement, feel free to include it on your OP @Williamtung, better yet, spread the word! :-D

    Thanks, still waiting for s22u and firmware(BRI/sm-s9080).
    Edit: The firmware has come up.

    you won't likely brick your device because I have taken a look and both devices are identical. So, I think it is fine to flash
    This is great! Thanks ! Because XID ( Indonesian) firmware supports fully native call recording. Samsung's OTA updates are also available every month.
