How To Guide How to ROOT Fold 4 [UPDATED - ANDROID 13 WORKS]

[bigchrizzieboy]

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

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!

- 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)

- 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.

- 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

You bolded the "EUX" part of the model name.. does that mean this will only work for global variants sold in the EU, not Asia? What about a phone sold in Thailand (SM-F936BZADTHL)?

I'll edit first post later to make it more clear and better links

Below the part you write there is some more text.
SSOAMC_SM-F936B_OXM_EUX_12_0045
EUX/-/EUX/EUX
is the text on my phone.
Probably you need THL

[Conan179]

Has anyone connected their Samsung watch to the Fold after rooting it?

 

[bigchrizzieboy]

Has anyone connected their Samsung watch to the Fold after rooting it?

It should work, i don't know why not?
For what's worth it my galaxy buds+ work fine with the galaxy gear app.
I have a old Gear S2 somewhere, i'll test it later and report.

 

[Conan179]

Root and Samsung smartwatches are not best friends.

For what's worth it my galaxy buds+ work fine with the galaxy gear app.

My buds live too, unfortunately that wasn't the question.

I have a old Gear S2 somewhere, i'll test it later and report.

I have the us variant. So no root for me until I get the right variant. But still the region lock is a worry

Hello

If I root the global Variant and use on Tomobile USA, will it re lock after couple of months like explained in the otjer post?

Thanks

 

[dirtybudha]

If it is confirmed that this method ONLY roots certain models, please be specific in the OP regarding which models are able to be rooted.

Just to clear up confusion or false hopes.

What happened to your test with your Gear S2?

 

[bigchrizzieboy]

What happened to your test with your Gear S2?

It does NOT work!
I already had the Wearable app (buds working fine).
Connecting my watch keeps it loading on "Finishing pairing".
I will try to fix this and report back (not the first time i got this problem).
Also Samsung Health doesn't work fix one post below.
Will test my watch more...

Edited the first posts

edit:
I need to find more up-to-date info and will post the solution:
Tried many solutions, even spoof devices doesn't work.
Ended in bootloop, now reflashing the device again.

Luckely i got everything backed up in Migrate
