Galaxy s9 plus problems for root - Samsung Galaxy S9+ Questions & Answers

On a Galaxy S9 plus with Android Pie I made the root by following the guide at this link https://www.the***********.com/samsung-galaxy-s9-plus-root/
On restart, I had problems with the Samsung account, but the phone worked. With the restart, however, problems start: the phone repeatedly tries to restart but fails; then I went into Download and I did a deep formatting, I followed the guide again from the point where he tells me to insert Elemental but already in the installation of Magisk there is the red writing of Error and if then I try to restart it says No SO installed. How can I solve? Thank you

Xiaomi Mi A2 "No command" Error (HELP!)

Good evening/Hi/Hello
I own a Xiaomi MI A2 64gb (black) with the OTA version 10.0.2.0. I successfully rooted it with Magisk 17.3 but had some problems after a while with some rooted apps so I decided to uninstall it. I went into the Magisk app and clicked on uninstall and pressed the button. It removed the Magisk manager from my app drawer and turned off my phone to later power it on with a laying down android droid with a warning symbol and the screen saying "no command". I've tried restarting it and still shows the same screen. I can reach android recovery and my bootloader should be unlocked. I think my firmware has become corrupt and that i've lost my original stock ROM. Can anyone help me with a detailed guide to fixing this problem (I'm new to root)?
Thank you, ruskiriri

Galaxy s4 M919 OS problem

Hello, I have a galaxy s4 M919. And I installed the optimized linageos 14.1 version 12 (thread link). It was working fine. But I tried to root my phone with odin and seemed like I was succeeded and after rooting, phone was reBooting. That rebooting process never ended (waited 7 hours). Phone showed samsung logo first and after that linageos animated logo continuously, phone was not hanged. Pulling out battery doesn't help. Pic below. (In the linked thread above, see comments #8575 to #8578). My personal belief it is happening 16 gb space probably run out, although I did emptied everything before installing.
1. Now what should I do? I want to use a stable os higher than 6.0, hopefully with root. Is that possible? Help me details how to install as all root options in recovery mode are gone. Even before that I want to format my internal 16 gb clean. Please help and TIA. or
2. In before I did backup my stock rom 4.4 with rom manager app, just with 2 or 3 clicks, and copied the folder in pc. How do I even use it? Pic below.

UPDATE : I have successfully installed my stock rom 4.4 on device. Rooted as well.

Cannot setup PIN/pattern after rooting Galaxy S9+ (SM-G965F) (Android Pie 9.0)

I'm using Samsung Galaxy S9 Plus (SM-G965F) (Android Pie 9.0) and I rooted my phone by using Magisk, after that I cannot setup PIN or pattern. After I setup PIN/pattern and I go to add biometrics screen, when I confirm my PIN/pattern, there's a popup tell me that "PIN/pattern is incorrect."
How I root my phone ?
1. Flash stock Android Pie firmware via Odin
2. Flash TWRP recovery
3. Boot into TWRP
4. Wipe data
5. Flash RMM-State_Bypass_Mesa_v2.zip
6. Flash no-verity-opt-encrypt-samsung-1.0.zip
7. Flash kernel ElementalX-S9-2.01.zip
8. Flash root file Magisk-v18.0.zip
9. Reboot
Did I do something wrong ?
OMG! Finally I've found someone reporting the same issue! My situation is a bit different, but the result is the same as yours. I have a Samsung Galaxy S9 (SM-G960F), and here are a few things worth noting:
I flashed the latest Pie-based firmware for the LUX-region from updato.com through ODIN
I flashed twrp-3.3.0-0-starlte.img.tar through ODIN
I tried flashing both no-verity-opt-encrypt-samsung-1.0.zip and no-verity-opt-encrypt-6.0.zip, and I flashed RMM-State_Bypass_Mesa_v2.zip
I did not flash a custom kernel
Finally, I flashed Magisk v19.2.zip
Everything seemed to work just fine (during my limited time on Pie), but I encountered the same weird behaviour as you when trying to set up my fingerprint. If I dared to reboot my phone after that, it got stuck in some weird loop where the SIM unlock screen will show for a split second, and then turn off again for a moment. That pattern was repeated continuously, and sometimes it rebooted itself. I could basically not get back into my phone.
Please, PLEASE, tell me you've figured this out!? Or if not you, then somebody else. For now, I've restored the backup I made through TWRP prior to flashing Android Pie, so I'm back to a rooted version of Android Oreo. I'll probably stay there unless I have a solution for this problem, cause I just can't see myself using my phone without root access.

Same problem
I'm using a Samsung S9 (SM-G9600) and my rooting process was quite the same as yours. Phone works just fine, but I can't seem to set any kind of lock screen (including fingerprints, which forbids me from using fingerprint unlock on other apps too).
It's Samsung security stuff, you'd have to remove it to be able to use security again.
As to what exactly you need to remove, I'm not really sure.
Anyone got any updates? I got the same problem. I tried removing the *.key files in twrp to reset the Pin. It does work and it resets the pin asking for a new one but when i set it to 0000 and try to register a fingerprint it says the pin is incorrect.

Problem whith installing Android on Redmi Note 7

Hello,
I have a Xiaomi Redmi Note 7 and 2 days ago everything worked fine, but I wanted to root my phone and I watched a tutorial to unlock the bootloader and install TWRP. Then I uninstalled TWRP because the superuser root permission gets automatically denied and I read that I need to uninstall TWRP and reinstall it. So I clicked on the "uninstall" button in twrp and I removed the app, then I removed the cache in recovery mode and I also wiped the Dalvik cache and then nothing worked anymore. I tried to start Android and I had to setup the phone again and when I did it to the "Checking for Updated" screen it stucked on the same screen. I waited several hours but nothing happend. Then I tried to install Android 10 with PixelExperience and I stucked in the first screen where the G logo is. I don't know what I have to do. I tried so many diffrent Android versions yesterday and nothing worked, I can not even install Android 9 anymore.
I hope someone can help me.
