-- FIXED ---

Please some help! I set everything back to normal. So also relocked boatloader to see if that went wrong. But starting from scratch I now cannot see the OEM unlock function in Developer Options!?!? What is happening?

@dr.ketan what am I doing wrong?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] J_Force:
Still not getting into recovery. Nothing seems to work.

If I flash CSC (instead ofHOME CSC) a factory reset is already performed right? So I use BL and CSC and CP from stock ROM with patched Kernel and patched AP? Should that work?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
Get TWRP from my ROM thread download area

Flash using Odin - Reboot to recovery - Flash magisk - Flash multidisabler (for links refer to post #337 ) - Format Data
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] J_Force:
Since TWRP is reported to cause issues I was looking to go without TWRP. I flashed BL-AP-CP-CSC-USERDATA and exited with the key combo while headphone plugged in. I see a white droid and blue circle and the text erasing and then it boots up again. Is it ready now? (I was not in the recovery menu)

--- EDIT ---

I guess this method is just not working (for me). No Magisk app after initial setup, no installed Magis after installing manager app, no additional steps/setup asked. Why is this not working? I never had this much trouble to root before.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] J_Force:
Is there anyone that can help me how to get into recovery when exiting download mode? Every single time it is like this:

- exit by holding vol down + side button

- screen goes black

- holding side button + vol up

- after logo screen a white droid and the erasing appear for a short time

- device reboots (while still holding vol up) and after logo screen the samsung logo appears and device goes after some time into initial setup

it should be possible, so what do I miss here?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
Since Android 11 you need s to keep device connected to PC

Rest of steps are correct.

In case it pass the screen, still you can hold vol down + Side key anytime to force reboot and again holding vol up + side key to enter to recovery
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] J_Force:
that was the solution. Now I am in recovery and did the factory reset. Waiting for the Note20Ultra to boot so I can do the initial setup and check for Magisk to be there or do the additional steps after installing Magisk Manager 8.0.5 app
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] J_Force:
@dr.ketan I am sorry and starting to feel stupid now. But after doing everything as stated in the instructions it is still not working. All steps checked but installing Magisk Manager nothing happens. What do I so wrong?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
Show me screenshot of magisk manager
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] J_Force:
here it is:
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
Try rebooting once or twice

If still issue, I suggest to try twrp method
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] J_Force:
did 3 reboots and started magisk manager every time after the reboot. Nothing happens when opening the app.

Edit: took a look at the twrp way, but that is not available for OneUI 3 and not able to update easily
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] J_Force:
This seems a lot easier than the methods in the first post of this topic. But where can I get the right TWRP? The linked TWRP is for the Dr. Ketan ROM and I think I will start with just TWRP and Magisk and maybe in the future try custom ROM. Also, to be sure, I can use ADB to push the Magisk file to the device after the wipe, right?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
You can get latest twrp from my rom download area or you can use one linked in post you quoted. I suggest you to manage sdcard/USB otg and keep magisk file there as some version of twrp have Mtp broken so you won't able to push (latest version won't have issue)

Thanks - after unlocking bootloader I received error upon flashing TWRP - "Only Official Released Binaries Are Allowed To Be Flashed" - any ideas on how to resolve this? I noticed OEM unlock isn't listed under Dev Options now, is that the issue?

EDIT, after a while the OEM unlock option appeared (greyed) in the Dev Options and so I was able to flash TWRP via Odin. After that it worked no issues following the instructions above. If anyone else gets the same issue, connect to wifi, piss about on phone for a bit without setting up google account, and the OEM unlock option should appear in settings, and that point you will be good to flash from Odin.

It is bricked?

Any idea to make boot up again?

Keep device connected to PC and Hold on Vol down + power till device force reboot. As soon as device reboot, quickly release keys and hold vol up + vol down. This will reboot to download mode

In case if you get same error screen again, still odin recognize device and you can revive device by flashing stock rom.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Piezak:
I finally got my phone updated, but is it really rooted?

I haven't rooted any thing since Note4 which I finally stopped using last fall; so it's been a while. I spent all afternoon on this phone.

At first I tried to perform Dr.Ketan's N9860 process in Post 84. It may have been me, but I was not successful.

Then I moved on to OP #1. First time through OP#1, I only had files in ODIN ...

AP: magisk_patched.tar

and

Userdata: Patched_Kernal.tar

I should also mention that I went from SamSung version 10 to 11 in this process. This passed, but phone was rebooting. Had to factory reset and start over.

Next time through I filled all of the fields in ODIN with files. (Downloaded from SamMobile; version 11)

BL: BL_N9860ZSU1CUA3_CL20517721_QB37777931_REV00_user_low_ship_MULTI_CERT.tar.md5

AP: magisk_patched.tar

CP: CP_N9860ZCU1CUA2_CP17974354_CL20517721_QB37561192_REV00_user_low_ship_MULTI_CERT.tar.md5

CSC: CSC_OMC_OZS_N9860OZS1CUA3_CL20517721_QB37777931_REV00_user_low_ship_MULTI_CERT.tar.md5

Userdata: Patched_Kernal.tar

But, there was no place to include: HOME_CSC_OMC_OZS_N9860OZS1CUA3_CL20517721_QB37777931_REV00_user_low_ship_MULTI_CERT.tar.md5

This was not flashed to phone.

One ...

I don't know if I needed to do anything with the HOME_CSC_OMC_OZS_N9860.... file? Is my phone complete? Do I need this?

Second ...

I don't see APK's: Super User, Titanium Backup and Root Files in my programs. I thought those were part of Majisk. What do I need to do?

Third ... I don't have TWRP, and can't install it as of yet. (In the future) What will that provide me?

Any comments are welcome and sorry if I don't have full understanding. I want to un-install some junk. How do I tell if I am rooted.

Thanks!

Good evening from Germany.

I bought a Samsung Note 20 Ultra 5G (512GB).

I made sure to get the Snapdragon version because it has more power and puts a little less strain on the battery.

Now I have a basic question:

Can I root my smartphone with these instructions?

The phone seems to be from Hong Kong.

I have already failed the first step, because no firmware is found for download for my phone.

I use root because of the adblocker, among other things. On my S7 I use the adblocker and I have a clean phone and can use almost any app without ads. I've been used to it for years now and would like to keep it that way.

I would be very happy if you have some input for me.

Thank you very much!

donnerwolke
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
Yes method remain same if your device have u locked bootloader.

But if you are rooting only for ad free then I suggest you to look for some non rooted ad free or consider using custom DNS.

Now a days rooting isn't same as era of s7.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] donnerwolke:
If I use an app to protect my phone from ads, then I still have the ads in my apps.

I also need root to access my system files. This allows me to access various databases and use them externally.

I also block my advertising at the DNS level (PiHole).

But it's not completely enough.

I am aware that a lot has changed in the last few years. That's why I ask here before I actually root my phone.

How can I find out if my bootloader is locked?

That's actually one thing I don't know yet.

Thank you very much.

Edit:

I was now once in download mode and I was in the bootloader menu.

Here is all the information.

My bootloader is locked.

What can I do now?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Sek0n:
I cant use your rom cause I'm have a SD version, but wanted to say thank you. That is the clearest/only detailed description for the process of updating without wiping I've seen; and it worked great.

Sorry for the noob question.

Is there any way to encrypt Galaxy Note 20 Ultra 5G (Android R) and MicroSD card too on an unlocked bootloader and rooted phone?

Or maybe... Is it possible to encrypt it before root and keep encrypted? Or the procedures would void it?

I'm looking for a way to avoid my Micro SD card to be easily read with an adapter, in case of stolen phone.

Thanks in advance!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] doggydog2:
guides to root with encryption are rarely published (because it means no TWRP and ROMs), but i only do it this way for all samsung mobiles/tablets. I don't have this model (but keen to hear someones confirmation), but i guess you follow the steps in nonTWRP way (avoid multidisabler) and that's it. SD card encryption should follow then, although i don't know how "easily" it will be read on another machine, quite opposite. For this reason I keep SD card unencrypted, and copy files encrypted (e.g. TitaniumBackup) to reach the same goal of having SD card readable when phone is broken.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] donnerwolke:
Hi Guys.

I flashed my phone this evening. I followed the instructions above. The only thing I did differently is that I took a different TRWP because my phone doesn't have an Exynos. It has a Snapdragon.

Otherwise, the procedure is identical.

When I come out of download mode after flashing, I press Volume Down and the Bixby button.

Then the screen goes black. Now I press the volume up button and the Bixby button. As soon as I see a picture, I just hold down the volume up button. A picture appears (there is also a warning triangle with Chinese writing) and then it vibrates briefly and then the device boots normally.

Link to .gif:

https://cloud.media-techport.de/s/zenYiCTHewbPeBw

I have Magisk preinstalled and my OEM unlock option is greyed out and active.

What am I doing wrong here?

I have the SM-N9860 from Hong Kong.

Thank you very much.

why step Preparation_7a) says patch patched boot.img? that seems duplicit. I'd understand transfer size optimalization, unpack boot.img, vbmeta.img, process with magisk, and archive it back, plus pack boot.img (thou not sure why use it at all).

Everything works in this guide until after flashing TWRP. The snag comes when you try booting into TWRP after flash.

Everything is stuck. The device does not let you get into recovery. Anyone knows a solution to this?

I believe that the TWRP in this case is not compatible with device.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] elmor0:
Why is rooting this device relatively complicated?

(I'm comparing to OP7T Pro & ROG phone 3 which I'm currently using).

BL unlocking was pretty straightforward for N9860.

Can we not just root by Magisk patched boot.img?

Or something Samsung-related that rooting has to be done as per OP instructions?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] elmor0:
Need Root & TWRP help/ advice please. For N9860 (SnapDragon; starting with Android 11 BRI region FW).

- BL is unlocked (OEM unlocking toggled on + greyed out; USB debugging is enabled).

- Magisk patched "AP_[device_model_sw_ver].tar.md5" & flashed via Odin fine (Is this step still necessary in reference to post no. 337?).

- Odin flashed TWRP fine (I've tried TWRP as per Dr Ketan's link as well as alternatively mentalmuso's Note 20 Ultra TWRP version).

Problem

: Unable to boot into (TWRP) recovery mode via VOL up + Power button combo as soon as I power-off from Download mode.

(I've tried several times both with USB cable left connected to PC & without connection).

It just keeps resulting in start-up screen with IMEI barcode @ bottom of screen & several message lines on top of screen e.g. FRP lock off; void x 01 etc.

I end up needing to Odin flash stock BL/AP/CP/CSC to get out of this hitch & start all over again......

Still unable to install TWRP............
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] elmor0:
Some more clarifications please

:

- Where does flashing vb_meta disabler fit into the rooting steps? (no mention of this in OP.)

- What file do I ODIN flash in the USERDATA field, if at all? (If I want TWRP recovery option.)

- Is ODIN flashing of Magisk patched [AP_.... _.tar] file needed? (was mentioned in OP but no longer mentioned in updated OP post #337.)

- Do I have to

reboot

@ each & every stage

of rooting process steps?
