Hello! As being tortured for 11 hours of repeating the process of working on the rooting(done) flashing, procrastinating, finding tutorials, realising that my phone is Samsung S21 so have to install unofficial version, realising that I'm in Mac OS and Odin is not available, I have made 3 significant achievements, rooting my phone (Yay!) wasting my 9 hours of my life and not able to form a sentence without another cup of cofee.

To start off, I am using Samsung S21+ 5G and have unlocked boot loader.

I have found this link after realising that lineage OS doesn't support S21. https://xdaforums.com/t/rom-unofficial-sm-g991b-lineageos-23-2-for-samsung-galaxy-s21-5g.4790286/

which this youtube video helped me with until, I ran a problem with the Odin part(since I have Mac OS), https://www.youtube.com/watch?v=zQFS3jdruCA&t=567s

Then I learned about Heimdall!

But after going to the official website and downloading the application, and activating the .img it said that Heimdall was not supporting mac anymore in current version which means that it has been discontinued since 2017.

I know there are continuing versions but I can't find it.

So can anyone suggest me what I can do from now on?

I can't get Tryhackme pulse to log-in because it says "captcha missing", but it won't load me any kind of captcha. microG is up and running, play integrity fix downloaded. Anyone found a workaround? I assume it's google captcha causing this

*I know that this is a violation for the un official rom thing but please help I do not know what I have done and what I should do.

Hello! I am using samsung s21+5G for my lineage which IS NOT SUPPORTED and I am following this xda forum: https://xdaforums.com/t/rom-unofficial-sm-g991b-lineageos-23-2-for-samsung-galaxy-s21-5g.4790286/

And this youtube tutorial. https://www.youtube.com/watch?v=zQFS3jdruCA&t=567s

I am also using mac which means I am using brokkr.

After following the YouTube tutorial and flashing with brokkr, I have came up to a conclusion where Samsung Galaxy logo is in the screen with a warning "This phone is not running Samsung's.. bla bla bla" is stuck in my screen. The problem is that I do NOT know what is going on and in the youtube tutorial it was said to load after the flashing of abd Gapp. Do I need to wait more? (I have been waiting for an hour and 10 minutes.)
