[Q] Samsung Galaxy Ace 2 Phone Rooting

Hello everyone
I am very new to this website as I just signed up and registered today. I am currently having a problem with my android phone, and I cant figure out how to resolve it.
The problem that I am having is that last week I was updating my phone when something in the device and caused my phone to become bricked. And after spending many hours on Youtube I finally found a video that helped me recover my phone by flashing the phones memory with clockworks recovery using odin and I was able to get my phone back up and working. But now whenever I turn my phone on I see the yellow triangle appear on bootup and I want to get rid of the triangle.
I downloaded the apk file for triangleaway but in order for me to be able to run it on my phone my phone needs to be rooted, and I have tried many ways to root my phone but it still says that my phone does not have root access.
My phone is a Samgung Galaxy Ace X II
Model Name GT-S7560M
Any help would be appreciated.
Thanks

[Q] [IMPORTANT] AT&T Galaxy S3 SGH-I747 Unable to Boot! Need Help!

(*Here's how the whole story started.) So I recently wanted to update my Galaxy S3, and for some reason the Baseband Version was different from other AT&T Galaxy S3 Devices. So, after I brought it in to Best-Buy they said they can't fix it, even though I contacted Samsung and they told me they could flash it with this ''SMART'' Tool (Which Probably is Odin3) Rooted or Not. I was tired of trying to fix this because, I was on 4.0.4 Ice-Cream Sandwich, and my friends bragging about the 4.4 KitKat Update they received. I literally tried everything, from clearing the Google Services and the AT&T Software Update on the Application Manager. I had the Baseband Version: I747UCLF5. I was tired of not getting the update, so I just flashed the Original ROM from Samsung-Updates, using Odin3. Samsung-Updates had only 4.1.1 Jelly-Bean, so I thought about just updating from Jelly-Bean.
(*Here's how the Samsung Galaxy S3 wouldn't turn on), and was stuck on a boot-loop.) So, continuing the story, I successfully updated to 4.1.1. Jelly-Bean. So, when I was on the 4.1.1 Jelly-Bean I checked for updates, and I successfully updated to 4.3 Jelly-Bean. Yes, I know that the 4.4 Kit-Kat update was out, so I continued updating the phone via OTA. When it finished, it started updating with AT&T Logo on top and the Percent with the Bar on the bottom. After it reached 100%, it was rebooting crazy. The Samsung logo went on and off and the phone went vibrating every second. I'm pretty sure my power button is not broken and when I put it in Recovery-Mode the same updating process came. (AT&T Logo, Loading Bar with Percent and a message saying ''Updating...''). Ever since that day, I re-charged it and I put it in Recovery-Mode, and same thing happens and when it finishes it's doing the boot-loop. I tried putting it in Download-Mode and tried to flash it with Odin3, but it didn't work at all. It had this error message. I'm pretty sure the Boot-Loop is caused by a Locked Boot-Loader. This is What it says in Download Mode.

Please try to help me with my situation. I am currently using a older phone, and I am desperate of getting my phone back. Thanks! Anything will Help!

Samsung Galaxy S8 SM-G950FD unroot problem

Hello,
I just purchased what was supposed to be a brand new Galaxy S8 in Hong Kong (I live in France) and once home found out it had been rooted. I am not sure if it is still rooted because I can't open Magisk Manager (the app says the version of Magisk on my phone is no longer supported by the app) and Root Checker says my device has no root access. Nonetheless, banking apps won't open, Samsung apps (Pass, Health...) either, and Netflix doesn't work.
I have gone through multiple threads to try and unroot my phone but flashing new firmware through Odin has failed and Smart Switch says my device is up to date (I have android 8.0 so it isn't).
My Knox has been tripped, my binary is 'Custom' and so is my Device status which leads me to believe my phone is still rooted.
There is no way for me to exchange my phone and Samsung have been unhelpful when it comes to providing a solution.
I would like to flash stock firmware on my phone but as I mentioned it consistently fails: either because of a PIT failure or a Bootloader Failure. My device model is said to be SM-G50FD but in Odin mode my phone says it is a SM-G950N which seems weird to me.
I am not experienced when it comes to rooting devices (and unrooting them) and am afraid of bricking my phone which is why I am asking for help here. If anyone could provide tips as to what I should do to get rid of the root I would be extremely grateful ! Thank you all.
flash samsung galaxy with odin done but unroot doest succesfully help me now what i do????
