[Samsung Galaxy Note 20 Ultra Questions & Answers] codenamefred:
Hello everyone.

I've been trying to root my Note 20 Ultra 5G (N986B/DS) running on android 12 using different instruction on YouTube and other websites, but so far I haven't had any lock and it's driving me crazy.

Here's what I have done so far:

1) I activated developer mode/unlocked OEM/activated debugging mode

2) Via Recovery Mode unlocked the bootloader so after doing a factory reset, when device turns on, there is a warning sign telling me that the bootloader is unlocked.

3) Downloaded the exact android 12 stock rom running on my device. (February security patch - XSG-N986BXXU3EVA9-N986BOXM3EVA9)

4) Extracted the rom in my computer (there are two different steps from two different sources):

4-1-1) Transferred the AP_N986BXXU3EVA9_N986BXXU3EVA9_MCL23524635_MQB48657513_REV01_user_low_ship_MULTI_CERT_meta_OS12.tar.md5 file to the device.

4-1-2) Using latest canary build of the Magisk installed on the device, I patched the ap file and then transferred it back to computer. (I also tried with the recent stable version of Magisk and the same occurred)

4-1-3) Put the device in recovery mode and then loaded BL/CP/CSC slots of the Odin3 v3.14 with the rom files and the AP slot with the patched file and then clicked start.

4-1-4) The result in devices recovery mode is: only official released binaries are allowed to be flashed (recovery) (photo attached)

4-1-5) since the operation didn't finish, I had to flash original stock files via Odin in order to boot to my device.

4-2-1) Extracted the AP file and changed the format of the file boot.img.lz4 to .tar file using 7zip and then transferred the file to my device.

4-2-2) Using latest canary build of the Magisk installed on the device, I patched the boot.img.tar file and then transferred it back to computer.

4-2-3) Put the device in recovery mode and then loaded the patched version of boot.img.tar file into AP slot of the Odin3 v3.14 and then clicked start.

4-1-4) The result in devices recovery mode is: only official released binaries are allowed to be flashed (recovery) (photo attached)

4-1-5) failing the flash process doesn't break the device and I was able to boot to my device.

Please if anyone has a clue, tell me the solution. I'm so desperate now. I've tried different workarounds in internet and non worked. I even tried installing unofficial version of TWRP and still the same message appears.

UPDATE:

I found a solution to install twrp using adb and fastboot commands. I got the device to be recognized by computer. but unfortunately "fastboot flash recovery boot.tar" command doesn't work and it sticks in sending the image state. So this method isn't working either.

UPDATE 2:

I found this post on xda dating back to 2018. According to this post I should wait 7 days (like "the ring" movie!) so that the message i referred to is gone and I can flash whatever I want.

I have had a galaxy s7 edge for some time now and I have experienced a lot of flashings with that device and never came across sth like this. Now I have to wait and see unless someone or me come up with a better solution.

P.S. I have some trust issues and I can't give team viewer or anydesk access to those who are able to help. So please don't ask for any. I kindly ask you guys to help me in anyway possible under this thread. If more information is required I will make sure to provide you with that.

Thanks in advance.
