Could someone kindly tell me how he manages to get root on S9 +? Ka front page guide no longer works for me. I am using twrp 3.5.0-9, disable dm verity 02.11.2020, magisk 22 and universal safetynet fix 1.1.1 module to bypass safetynet. Unfortunately, the smartphone is slow and has sudden restarts. Where am I wrong? Thank you

Hallo
[Samsung Galaxy S9+ Guides, News, & Discussion] Clayman_32:
Followed the guide for flashing Q on Galaxy S9 SM-G960F, flashed Devbase rom, restored all aps and settings, last app I installed is Family link for children and all working without problem till the moment when I try to restart with built in restart button in the quick panel (this is the second time in last 12 hours) , after that the screen goes black and I have the message in top left corner "Custom binary blocked by FRP lock". First time I reinstalled original firmware with Odin, redo all the Twrp stuff and reflashed Devbase but this time I have a full Twrp backup and I try to restore it after reflash with Odin. Anyone know the reason why phone got FRP lock and how to prevent it?
[Samsung Galaxy S9+ Guides, News, & Discussion] spawnlives:
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 )
[Samsung Galaxy S9+ Guides, News, & Discussion] Clayman_32:
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?
[Samsung Galaxy S9+ Guides, News, & Discussion] spawnlives:
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 ?
[Samsung Galaxy S9+ Guides, News, & Discussion] sosimple:
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?

Zackptg5 - Android

zackptg5.com

Is there anything else we should flash, any other file? (exept magisk).

Thanks,
[Samsung Galaxy S9+ Guides, News, & Discussion] spawnlives:
No

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.
[Samsung Galaxy S9+ Guides, News, & Discussion] chestervn:
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 )
[Samsung Galaxy S9+ Guides, News, & Discussion] tommy_der:
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.
[Samsung Galaxy S9+ Guides, News, & Discussion] spawnlives:
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.
[Samsung Galaxy S9+ Guides, News, & Discussion] tommy_der:
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.
[Samsung Galaxy S9+ Guides, News, & Discussion] spawnlives:
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.
[Samsung Galaxy S9+ Guides, News, & Discussion] tommy_der:
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.

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.
[Samsung Galaxy S9+ Guides, News, & Discussion] mgzavala:
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.
[Samsung Galaxy S9+ Guides, News, & Discussion] 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?
[Samsung Galaxy S9+ Guides, News, & Discussion] tommy_der:
First of all everything has worked so far, TWRP 3.3.1.1 is installed with the patched ODIN, then I installed /e/ OS, Magisk and at the end the disable...zip.

What unfortunately happened since flashing TWRP: the display just goes off and can't be moved to turn on again.

At the beginning, pressing the power button several times was enough, now, in the middle of setting up the OS, it goes off, flashes only once in a while and I can no longer get into the system, can no longer perform any actions.

Can the flashe from the TWRP cause a graphics error???

Or is the refurbished phone simply out of order?

I want to root my Samsung S9+ (SM-G965F) phone whith a stock rom using TWRP and Magisk.

I am currently on Android 10 (Q) AP_G965FXXS

I've read lots of info from xda and internet, but the needed steps are not clear to me.

Can someone please confirm is TWRP/Magisk is possible on a Samsung S9+ and

what the versions of patches i should use ?

What Odin version should i use?

Several guides use version Odin3-v3.13.1.zip,

but latest i've found is Odin3-v3.14.4.zip ( Latest Stable version is Odin3-v3.14.1.zip )

I want to flash TWRP v3.60: twrp-3.6.0_9-1-star2lte.img

Is it neccesary to install the RTMM Bypass ? ( and ad what step in the procedure should i do this)

RMM_Bypass_v3_corsicanu.zip

Which no-verity showld i use ? ( there seem to be lot different versions )

no-verity-opt-encrypt-samsung-1.0.zip

no-verity-opt-encrypt-6.1.zip

Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip and rename it to: Disable_Dm-Verity_ForceEncrypt_quota.zip

Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip

How can i install Magisk ?

( S9/S9+ supported in Magisk v16.6 and above) :

Latest ZIP file in releases is: Magisk-v21.4.zip

Can i rename Magisk-v24.1.apk to Magisk-v24.1.zip and install this version

or should i install Magisk-v21.4.zip and upgrade to Magisk-v24.1.apk

( the files arm/magiskboot, arm/magiskinit and arm/magiskinit64 appear to be missing in v24.1 )

Should i install the OEM Root fix ? (and what is the purpose )

I have the following issue after rooting. Sometimes when I open supersu, it opens to a black screen and I have to go back to the main menu, but the device doesnt reboot. If I close supersu from the recents list and try to open it again, I get the same black screen. Meanwhile, all programs that need root to do their thing keep working normally, albeit without the usual notification about root access being granted.

Any advice?
[Samsung Galaxy S9+ Guides, News, & Discussion] gaww:
I hope so. It crashed when I tried to get back into TWRP - it was gone, as well as OEM unlock when I checked download mode.

I was going to try adb/fastboot unlock, but won't go into bootloader mode - just reboots. Even in stock recovery, also just reboots.

So hope OEM unlock shows up in a week ...

[Samsung Galaxy S9+ Guides, News, & Discussion] salada2k:
I flashed this successfully. But root isn't working. SuperSU hangs on a black screen. This is after running the first root app and granting permission. I then see lots of 'app was granted permissions to run interactive shell' but these seem to be incorrect. No root apps are working at all. I also flashed a standalone SuperSU . Still no dice. Tried custom kernel and still no dice on root. Followed all instructions to the letter, but to escape boot loops had to flash dm-no-verity image posted earlier. Also tried the Alexndr custom rom. Still no root. Apps like Google Pay are broken (detect root) but root is at no stage working for me at all.

[Samsung Galaxy S9+ Guides, News, & Discussion] steve187ci:
same here rooted fine and super su hangs on a black screen and wont give root access just hangs every time.

uninstalled superSU and reinstalled updated bianarys via twrp and via app then causes phone to go in to a boot loop and have to re root from start again.

root works for first day then just goes to a lack screen or a spinning circle.

tried v1 v2 and v3 all same.

im going to install stock rom until a good stable fix is out cause in past 2 weeks ive had to reinstall os 10 times plus now

Any advise would be great
[Samsung Galaxy S9+ Guides, News, & Discussion] dr.ketan:
You mean it works for some times then causes issue?

Haven't you selected kernel while flashing V3?
[Samsung Galaxy S9+ Guides, News, & Discussion] steve187ci:
Ok I've tried version 3 again selected kernel . . It's happend again but I have noticed super su works but soon as you reboot phone it no longer works. It just hangs and black screens.

So I tried to uninstall super su again and reinstall it and it asks me to update binarys . Once done phone goes in to boot loop ever time all versions.

When I say super su works it seems to be until phone is restarted then I get black screen or spinning circle then force close .. drains battery quick swell as it keeps trying to run in back ground.
[Samsung Galaxy S9+ Guides, News, & Discussion] snooyy:
so I went through the whole root from a new fresh stock rom, and uninstalled the super su from the root and reinstalled it from play store, asked me to update binary, chose from recovery instead of from app, stuck at: skipping digest check: no digest file found, had to flash stock again to get out of it.

according to your experience then the other choice of updating the binary from super su itself wouldn't work either. how did the other people get their root I wonder, is there anything we missed?

This might help someone maybe.

I has issues with SuperSU, including appcrashes and root not sticking. Had that annoying "binary needs updating" (and not working) too.

I fixed most issues by uninstalling the app then rebooting to TWRP and there first wiping Dalvik/cache then installing the SR5 SU attached and finally wiping Dalvik/cache again. Booted in 15 secs and the SuperSU app works flawlessly and root is sticking.

Everything worked great no problems. I just received my SM-965f/ds today. Oem unlock did not appear in developer settings after tapping on build number numerous times and enabling it. I scrolled to the top hit search and searched Oem and nothing popped up. Then I searched unlock and multiple items popped up as expected. I scrolled to the bottom of that and it had an option to enable Oem unlock. I tapped on that and it took me back to developer settings and the option to unlock was there. I enabled unlock and followed your instructions to the letter and was rooted in record time. Can't say this will work for someone else or I got extremely lucky but this was a great surprise for me.
