Root Bootloop after successfull root

[Zebastian G]

Let me just start off-- I havent rooted a phone in manymany years and my skills are pretty much gone.

I don't know why, but shortly after the successfull root, my phone started bugging and glitching. Perhaps because I deleted all the Bixby files with SuperSU(??)

Anyways, I decided to reboot my phone the ordinary way but it got stuck in a bootloop with the SAMSUNG logo, which appears right after the first boot logo with the phone's model etc.

It's rooted with Magisk. I tried to do the rooting over again from TWRP and wiped the phone -- but still the same problem is there. I guess it's the shi**y Bixby files that still are removed.

My best guess is that I need to reinstall the Android OS and start everything from square 1 because, somehow, the Galaxy needs those Bixby files, just because...? Thanks for any help my fellow Androidistas!

Bixy is a app that the OS is built upon on even if all it does it similar to what Google assistant does, the OS considers it a core app and when you deleted the apps it cannot boot the OS because 1 of all the core apps are missing so it fails to boot

yep head on over to sammobile and flash the correct firmware for your device.

next time before you go make changes after you root your phone, make sure to do a nandroid bsackup with twrp.

If your phone is stuck in boot loop at startup after rooting it, that's typically an indicator the installed Android OS has become corrupted to the point the phone can't boot up anymore. With no functional operating system, the boot process simply fails.
You need to re-flash the ROM, get your phone working again, and then try again. Note that flashing a stock Samsung ROM will install a clean (that is, non-rooted) OS, along with a stock Recovery. Go here, download the appropriate ROM for your model, and follow the indicated instructions on the flashing process:

Be sure to select the ROM that exactly matches your specific phone model (i.e. SM-G975U) and your carrier. Don't mix and match, ROMs are specific to their respective models. If you do feel the urge to experiment, using the wrong ROM may just soft-brick your phone and you have to start over using the correct ROM you should have used anyway; worst case scenario is you'll hard-brick your phone.

I'm between 2 different CSC Firmwares. 1 is a very local carrier specific version and the other is for multiple countries including my area.
How can I check my CSC without being able to boot? All the examples is with a bootable phone.
What's the worst that can happen with a ROM without the right CSC? I think maybe nothing, as long I DO choose one of those 2 I mentioned?

Thank you, great wizards!

Is that 'very local carrier' actually your carrier?
If it is, that's the one you should use. If not, use the other one.

At last: Are the 2 files for Version 9 both the same, but the top one an updated file? https://www.sammobile.com/samsung/galaxy-s8-plus/firmware/SM-G955F/NEE/

This is for my S8+ which I'm flashing first.

I've bricked Android devices before, and don't remember what I learned from that all those years ago. Don't want to do it again... Thanks.

Have many non-similar PDA versions on: https://updato.com/firmware-archive-select-model/?q=SM-G955F&exact=1&r=NEE&v=Pie(Android+9)&rpp=15

If I'm correct -- PDA is just the build, and I can use 'em all?

The CSC and PDA are version identifiers to the actual ROM itself, so being their own builds no, it's unlikely they'll match the ROM that's currently on your phone. As for when there are two identical ROMs (both ver. 8 or whatever), usually opting for the latest one will include patches that have been applied since the previous one.

I'm not 100% sure I understand you there. i apologize. Your first sentence confuse me.
Do I need a ROM that is matching the one currently on my phone?
Second: All the different ROM's for Android V. 9 on Sammobile or Updato all have different PDA's, and I can use them all? But opt for the newest when possible? If I choose one with a release in June -- can I after a successful flash, update to the newest patches?

Sorry, I know Im a dummy at this point.

Well it might be better if you looked at CSC and PDA as specific identifiers for developers to keep track of each build they create. You don't need to keep fixating on that as it's for the most part irrelevant for what you need to do (flash the appropriate ROM to get your phone working again.), It's not unlike if you're buying a set of spark plugs for your car, pay attention to getting the appropriate ones that are made for your car's engine, don't worry about the bar codes on the packaging.

Yes, you're going to encounter hundreds of ver. 9 ROMs, but just to stress this point again, NO, only a handful of them are going to work with your model. Smartphones are generally similar in outer appearance but every different phone model has its own, unique hardware configuration on the inside. ROMs consist of software, drivers, firmware, etc. to correspond with only that hardware configuration. So again, no, you cannot use them all.
