So I have the Z Fold4 SM-F936U1 - XAA this is the unlocked US version and there is no "OEM Unlocking" after Developer options are enabled. Does this root method require an unlocked bootloader? I would assume so if flashing modified firmware is necessary?

I take it the US models and users will need to wait for a different method?

Seems to be the case. So I was also wondering if you have to have the bootloader unlocked to flash firmware through Odin. And can you flash the EU firmware onto an American AT&T version with Odin, is it even worth it? I've wanted to see how Android 13 is.. Ive pretty much only rooted OnePlus phones.

Time for Android 13 update, fresh install for me with root.
Little effort to write down my steps (hope it helps somebody)
2022_8_8_12_6_11_257.jpg


Work in progress for me,
I've writen down the steps for myself, hopefully it will work.
I'll update this post and edit first one.

I skipped the steps that where not needed, i was on my already rooted phone developer, oem unluck.
See first posts how to do that basic steps (not possible on all phone's!).

- In short the steps i used:
1: Download file (i used FRIJA this time) - XDA - GIFTHUB -
2: Unpacked the file - 7-ZIP
3: Backup everything i want with Migrate - PLAY STORE LINK - XDA -
4: Copied the backup files to my computer to be very safe - with USB cable
5: copied the AP file to my phone - with USB cable
6: patched the file with magisk and copied it back to computer - GIFTHUB -
7: Reset my phone in (i've got everything prepared and a good backup, no stuff left). - On phone action in settings -
8: Setup phone and enabled developer options and usb debugging (needed for Odin)
9: rebooted phone in download mode (ADB: adb reboot download)
10: Flash the files with Odin - HOMEPAGE -
- I wanted a full wipe so is used the CSC_OXM_F936B.... file
- If you want to keep data use the HOME_CSC_OXM_F936B... instead
- Beware, i've NOT tested a update instead of clean install but that is what i read in other posts!
Please comment if the HOME_CSC_OXM_F936B... method works for you

11: Clicked through the setup (let the phone connect to internet)
12: Installed Magisk on phone and finished setup- GITHUB -
My phone is clean, uptodate and rooted :)
13: Copied my backup files back and restore some apps what i want.

- Same steps with screenshots:
1: Download file (i used FRIJA this time) - XDA - GIFTHUB -
1669121283918.png


2: Unpacked the file - 7-ZIP
1669122450143.png


3: Backup everything i want with Migrate - PLAY STORE LINK - XDA -
It gave some error on file size, i edited options in Migrate and will retry.
This time i make migrate helper only backup.
Again error, i left some apps and make smaller backups (not all apps at the same time now).
Working by creating backups from 20 till 30 apps a time. Took long time, but better safe then sorry.

Confirmed that unlocking the bootloader on a F936N will stop the camera from working.

I have flashed files with Odin, but I don't understand how to "Patch AP in Magisk (on phone action)", as I read on the tutorial. Can someone tell me how to do it, please?

Sure:
- Open magisk
- Choose install
- Select and Patch a File
Choose your AP file here and Magisk will do the magic.

I think screenshots below will help.
Let me know if it worked :)

Hey guys, I'm completely new when it comes to the rooting scene. I've been watching this thread ever since I bought my Fold 4. Unfortunately, I have the SM-F936U model
Did anyone ever find a method to root it?

Thank you for trying to help and sorry for my delay.

As I see it, I have to patch the ROM file(s) with the Magisk-v25.2.apk before injecting it in the phone via Odin. But the Magisk .apk file is not executable on a computer. Hence, my question: How do I do that. How can I
"- Open magisk
- Choose install" ?

This is the only thing I don't understand and don't know how to do on your well detailed tutorial.

    Do you mean that you carrier unlocked your UK phone?

    No they mentioned :
    - Can all modeld be rooted? No, this doesn't work on all models (as stated here and some more info here):
    SM-F936U(/1) - US model - Unrootable
    SM-F936W - Canadian model - Unrootable
    SM-F936B EUX - European model - Rootable (my telephone)
    SM-F936N - South Korean model - Rootable
    SM-F936B(/DS) - Global model - Rootable***
    ***B models purchased in UK are not guaranteed to get an unlocked bootloader due to brexit as noted by user @白い熊 and confirmed by @kaos_king

    and i got the version SM-F936B(/DS) from uk (box said uk ) and was able to unlock the bootloader

    now i need help compiling the kernel for nethunter ... (https://forum.xda-developers.com/t/nethunter-build-help-kernel-system.4541193/ )

    Nice Thread...

    Anybody knows for sure or has experience in if that works with the newer "Fold 5" model?

    Thx

    Some good news have come to light. It's still no root or unlocked bootloader but it may leed to it

    https://forum.xda-developers.com/t/...mobile-devices-no-bl-unlock-required.4543071/

    It's unfortunate the other models have a method to root as it seems no one is working on rooting the US version due to this. I wonder if it will be a year or more before we see root on the US version.
    Don't count us out yet, I've been messing around with the CSCs and finally was able to get my U to flash U1 XAR firmware and went to change CSC to see if there was any new "Compatible" Csc sure enough the XAR varient appears to be compatible with all US and just so happens to be a B varient as well WWD witch I'm running Said WWD csc , just more testing to be done!!! We will have are freedom sooner then later I doo believe!

    Time for Android 13 update, fresh install for me with root.
    Backup and restoring apps, much work but it works and is worth it for me.
    Little effort to write down my steps (hope it helps somebody).
    See post 73
    2022_8_8_12_6_11_257.jpg


    First things first:

    - This DOES NOT work on all models:
    The US (and maybe more models) do NOT allow root.
    Only the B, N, and /DS models are rootable at the moment.


    - Also there are known issues with Samsung Health and Gear (connecting watch)
    - See second post for F.A.Q.!


    I was able to root my Fold 4 and under here are the steps.
    I hope it make sense and otherwise i will answer questions/try to help.

    Steps in short:
    - Enable Developer Mode (on phone action).
    - OEM unlock (on phone action).
    - note the software version.
    - Download needed firmware.
    - Patch AP in Magisk (on phone action).
    - Finish OEM unlock in Download mode (this will RESET the device)
    - Setup phone again and connect wifi (that's important i guess).
    - Flash patched AP with Odin


    Steps with more explanation and screenshots:

    - Enable Developer mode (on phone action)
    Navigate to Settings > About device > Software information >
    Click on Build number (7 times) until you see a message that says: You are now a developer!
    one-ui-developer-mode4.jpg


    - OEM unlock (on phone action)
    Navigate to Settings > Developer Options (at the Bottom) Find OEM unlock and toggle it to on.
    If this option is not there then probaly your phone cannot be rooted (see second post)
    1666691373282.png


    - note the software version:
    Navigate to Settings > About device > Software information > Software Version.
    Example (bold is what is needed):
    SSOAMC_SM-F936B_OXM_EUX_12_0045
    EUX/-/EUX/EUX

    - Download needed firmware:
    https://samfw.com/firmware/SM-F936B/ (I downloaded from here)
    https://www.sammobile.com/samsung/galaxy-z-fold-4/firmware/
    https://samfrew.com/model/SM-F936B/

    - Patch AP in Magisk (on phone action)
    Download and install Magisk on your phone:
    https://github.com/topjohnwu/Magisk/releases/latest
    Copy the AP file to your phone example:
    AP_F936BXXU1AVGA_F936BXXU1AVGA_MQB54005121_REV00_user_low_ship_MULTI_CERT_meta_OS12.tar.md5
    to phone, patched file in Magisk and choose the AP file.
    magisk_patched-25200_KYFoy.tar is created.
    Copy this file back to computer next to the other firmware files.

    Now you've got everything and you can start the proces:

    - Finish OEM unlock in Download mode (this will RESET the device!)
    This was hard to do; i hope the instructions are do-able, please comment.
    power off, hold volume up&down, connect USB cable to PC.
    the screen is dark and hard to read.
    HOLD volume up key to unlock bootloader and press volume up again to confirm.
    bootloader-unlock-2021.jpg


    - Setup phone again and connect wifi (that's important i guess).
    After finishing the setup check under developer options or bootloader unlocked is on and greyed out.

    - Flash patched AP with Odin
    I flashed the whole firmware (could be usefull with new samsung updates), took about 4 minutes:
    BL
    AP (patched file) <- i guess only this one was needed.
    CP
    CSC

    - Setup the phone, install Magisk and check.
    After finishing the setup, install Magisk, it will do some last finishing setup (and reboot) and you've got root!
    My phone is rooted, LSPosed Zygisk also working without any problem.

    FAQ: got questions? ask them in this thread and it it make sense i'll edit this post

    - Can all modeld be rooted? No, this doesn't work on all models (as stated here and some more info here):
    SM-F936U(/1) - US model - Unrootable
    SM-F936W - Canadian model - Unrootable
    SM-F936B EUX - European model - Rootable (my telephone)
    SM-F936N - South Korean model - Rootable
    SM-F936B(/DS) - Global model - Rootable***
    ***B models purchased in UK are not guaranteed to get an unlocked bootloader due to brexit as noted by user 白い熊 and confirmed by kaos_king

    The global model has the bands most similar to the American one. The south Korean model doesn't use the same 5G bands used in america. The only models that can be found on ebay are are U and N.
    Discussing is happening in the other thread from page 3 there's more information.

    More info/questions? please post here and i will edit this post if needed

    - Can i update my Fold 4 after root?
    :
    Automatic updates will not work!
    You can however download new firmware and keep your data: see pvillasuso his post
    in this thread: Update and keep root and data
    Grab your latest firmware , get the AP file and patch it with your magisk app
    Then Odin flash the full firmware , using the AP magisk patchfile @ AP Tab
    Use CSC_HOME file @ CSC Tab ( to keep all your data and actual setup )
    Done > Updated with root + data + setup

    - Any known problems with device after rooting it?:
    First off all rooting can have his downsides, think about global things like banking apps not working.
    Besides that; Not many Fold 4 users are rooted yet i guess, so it's possible there will come known issues.
    For now:

    - Gear WearAble is NOT working correctly (my buds work, my watch keeps pairing).

    - Samsung Health is NOT working correctly (error on opening)
    FIX: Version from here: https://adil.hanney.org/SamsungAppsPatcher/ is working fine.

    - Camera's are working fine as far as i know for now.

    More info/questions? please post here and i will edit this post if needed

    I root my phone for many years so the first thing i finded out was: how to root fold 4.
    It's easy and i can help you, just get the damn phone :p
    I have the us variant. So no root for me until I get the right variant. But still the region lock is a worry
    2
    Here's my post for a VERY DETAILED WALKTHROUGH how to do it on a Samsung Tab S8. It's the same procedure on the Fold 4.

    Is there already a TWRP?
