[08.01.19][Guide] ROOT S9+(Exynos)Magisk + OEM fix + EFS Backup Tool

[Clayman_32]

You could try deleting all accounts on your phone ie: google etc then reboot phone and check accounts are deleted.
You can check in download mode the status of frp lock ( should be off )

I try all of that and no luck, the problem is Family link, in phone that is under monitoring the app switch OEM unlocking to off and this lead to FRP lock error. For now I reflashed the original firmware in phone because I need Family link.

My S9+ is on Android Q. How to root?

Two methods. Both require oem unlocked, kg status is in checking state ( and FRP turn off ).

1. Using Magisk app patch the boot.img file ( or AP file ) then flash (all) files in odin. ( Device is still encrypted )
2 Flash TWRP then Magisk and Disable_Dm-Verity_ForceEncrypt. ( Device is un-encrypted )

Hi

Can I use this guide https://www.xda-developers.com/root/ to unroot my S9+ with Magisk and patched firmware ? So without installing TWRP ?

Hi to all. Has anything changed in 2021?
-Twrp 3.4.0, I read somewhere only this version work?
- Disable_Dm-Verity_ForceEncrypt is this file for s9+, Android 10?

Thanks,

If your on later version of android 9 and 10 then the use of RMM bypass zip is not necessary.
Install twrp - latest version works fine for me. If needed you can change version within twrp or odin.
Optional - magisk - magisk can be installed at any time.
Install no-verity zip - may have to add quota to the file name.
The old guides are still relavent wnen installing twrp but the files needed may have changed or upgraded.

Hello there, I've done GG search and quite confused with this part, hopefully got clarified.
I rooted my S9 with Magisk using Odin. I'm happy with my phone now, and I want to do a Backup, so if something happens, I could return to the current stage of the phone. My question is:
(1) I can do a full backup? Meaning to say, i can backup the current rom with everything in it. All I need to do is to restore, then everything is back to this current stage?
Or, (2) I can only backup Apps and Data. I would need to restart the rooting process, install Magisk and then restore my apps and data later?
thank you so much,

Hello
I found this thread because I was looking for a GalaxyPhone that can still be rooted relatively easily.
Subsequently, I bought a refurbished S9+ DUOS. Unfortunately, this already has AndroidQ.
Can I simply reset the Android version by flashing a stock Oreo or Pie?
Is this variant for rooting still current and runs the phone stable with it?
It should be installed a /e/OS, does anyone of you have experience with this?

Thank you and many greetings
Tommy

Can not downgrade versions due to binary ( bootloader ) version numbers.
Same method to root/twrp your phone as previous methods.
Custom ROMs check In relevant guides. At the moment on my S9 running lineage 18.1 ( A11 )

Hi and thank you.

Summarized for me once again:
I flash TWRP via Odin, then in recovery Magisk and /e/ OS.
Then I take this file: "Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip" and rename it to: "Disable_Dm-Verity_ForceEncrypt_quota.zip" and flash it last.
Is this correct?
If I flash anything in the following time, e.g. an update of the OS, I always flash at the end the "Disable_Dm-Verity_ForceEncrypt_quota.zip"?

Thanks and bye, Tommy.

Basically yes. See your relevant guide for installation.
I would install you OS first then magisk
No-verity zip needs to be install once unless you flash stock ROM again and start all over again.

I read in this thread that TWRP can no longer be installed from a security patch level of 01.05.2021 onwards. My S9+ has a security patch level of 01.08.2021 :-(
So root is completely prevented, or am I seeing this wrong?
Thanks and by, Tommy.

You can still modify your phone on the latest firmware ( depending on model number ).
The ability to unlock bootloader and have kg state ( and/or RMM state ) in checking ( normal ) mode is not firmware versions related.
Updating firmware means due to binary ( bootloader ) versions you can not downgrade to previous version. You can only flash the same or higher.

Hello, my last rooted phone was a Galaxy S7 and that was comparatively easy.It has worked since 2016 and I haven't bothered with these things any further. Now that it's broken, I'm forced to root a new one and I'm starting to not understand the connections anymore (maybe it's my bad English, I'm a German native speaker).
In post 952 you wrote that a downgrade is not possible.
What do I have to check to see if it is possible? And with which firmware is it possible (I'm assuming Stock, right?).
Maybe you can give me a few more hints?
Thank you and regards, Tommy.

Under standing your firmware name. This is for another model but is the same for your model. Refers to samsung stock rom only.

Also make sure FRP ( factory reset protection ) is OFF

Note on later version of android 9 and 10 ( Q ) you don't need to use the RMM bypass zip. Only have to worry about KG status.

Hi, I have a Galaxy S9 SM-G960F, UK version, I was wondering if I can use this method to root the phone while it's in reset mode with frp lock. I've been trying different methods to bypass frp lock with no luck. I found a video saying that if I flash a different rom I can bypass frp using method on the video. Haven't been able to flash another stock rom so I was hoping that maybe if I root the phone it will let me flash a rom that will let me bypass frp.

 

[tommy_der]

Hi, me again. The baseband version of my phone is the G965FXXUGFUG4.
If I can set the OEM unlock on the phone tomorrow, after the 7 day period is over I have to check afterwards in download mode if FRP = OFF and no other status is PRENORMAL. If that fits, I can flash TWRP via Odin. If not, I can try to install a newer software version, then have to wait 7 days to try again.
Is this correct?

How can I manipulate the KG status?
