Question Black screen after Odin flash

[ibrahimhussein2035]

So , I tried flashing my phone using Odin. So I patched the official firmware from Samsung using Magisk, then loaded it on Odin and everything went well until it was time to boot. The phone got stuck in a boot loop and when I pressed the power button, things have been dark ever since

Welcome to AC!
Can you get into Download Mode ?

Why did you flash? Some problem or other?

If your phone is stuck in boot loop that indicates the installed Android OS was corrupted in some way -- the phone starts up, can't find a working OS in the boot up process, so it just cycles through endlessly.
You need to manually reboot your phone back into its Download mode, and then using the Odin utility flash the stock Samsung ROM again to restore the phone back into working condition again. But this time be a lot more judicious about using Magisk to root your phone. Make sure to read through all the relevant Magisk instructions, their documentation is a collection made by a lot of trial-and-error/success experiences.
