So I left the Galaxy phone for a while and last time i rooted was back when I had the S7 Edge for a while, but I recently got a S8+ on Nougat version, I know the newer Oreo firmware are unable to root, but I'm not sure if the Nougat version I'm on is able to be rooted, I'm currently on build QL1, but looking online, I get near no info or not any info at all about this particular firmware (Sammobile doesn't even have this firmware on ATT.) So I wanted to see if this particular build is rootable or is it just basically best to avoid rooting at this point.

Hey guys. I was wondering, what is the process for android firmware updates? By this I mean, when I owned an iPhone (any model) after I updated the firmware there seemed to be remnants of the old firmware version and it would cause issues through the phone, at which point I would have to go on my computer, restore to the newest firmware essentially formatting the phone and re-uploading the new firmware on the phone. After that all was fine. Is this necessary on android in order to get a new, clean version of the firmware on the phone or does the update process do this throughout the installation? I haven't had any issues yet with the newest AT&T Nougat update, but I was just thinking about this and figured I'd ask before anything did happen, if it's like my old iPhones...
BTW, I'm on AT&T Samsung Galaxy S7 with Nougat 7.0
Hey so.. Phone's root bugged out yesterday and I downloaded twrp and decided I should upgrade it to Android 8.0 then root it. After many hours of failures I managed to flash a 8.0 but I couldn't make the CSC to work, since my phone is region locked to another country so I decided to go back to 7.0 and try again.. but now here it gets complicated because I really don't know what to do. I'm not sure how exactly to go back from 8.0 to 7.0.. Can someone give me detailed steps on what should I do.. I'd be very grateful!
PS. I don't know if I'm posting this in the right forum thread.

Same site, or sammobile can be used to get the firmware files to flash with Odin
Note: The last version of 7.0 locked the ability to downgrade, I haven't gone to Oreo so can't confirm, but it ability to downgrade may also be removed from Oreo.

I can confirm, downgrading from Oreo 8.0 to Nougat 7.0 is possible, even without tripping knox.
It's just flashing the previous firmware with odin and factory reset the phone before first run and you're fine to go
I bought the unlocked USA version of the S8+ (SM-G955U1), and it came stock with Oreo/8.0. I've tried multiple times to flash firmware with Nougat so that I can downgrade and root, because all other firmware for Oreo doesn't work. I don't know if the process is unsuccessful for me because the phone wasn't ever updated from 7.0 to 8.0 or what, but at this point I'm willing to resend this phone and just the Internantional/Exynos version if nothing else works.
Thanks for the help regardless.
I recently bought a new unlocked Samsung Galaxy S7 to use on AT&T. It is running on Android 6.0.1. There is no OTA update coming to my phone. I've downloaded Samsung Smart Switch to my PC and it states the my phone is up to date. Obviously it is not, since it is still running on Marshmallow. I figured out that the phone was originally set up for Sprint, as the model says SM-G930P on Smart Switch. The model number under About Phone states SM-G930a, and is running baseband G930aucs4apk1, csc code ATT. I have verified it is a brand new phone, never rooted. Samsung suggested I go the Best Buy to have the phone updated there. However, the closest Best Buy is 90 miles away and said they do not do the updates in store. I am resisting using Odin to do the update, as I don't have experience doing this. But at this point I'm thinking this is the only option. So far I have downloaded Odin 3.13.1 patched and Samsung drivers to my PC. Can I go directly from Android 6.0.1 to 8.0 without having to install Nougat? Which Oreo firmware do I need for my particular S7? Is it possible/easier to update my phone by installing the firmware using my phone's sd card instead of Odin? I am only wanting to update a stock version without rooting. Thanks for any insight.
I have a Samsung Tab S3 tablet LDU, which identifies itself as an SM-T820. It's running Android 7.0. There is an official Android 9 Pie update for my region, but as I have a Wifi only model and no carrier I was never offered an OTA.
I'm thinking about flashing it but I don't know whether it's likely to brick my tablet, as it's an LDU.
Is there any way to test or know what the chances of success are when attempting to flash an LDU with official firmware for non-LDU models?
Before I proceed, what is the easiest way to fully backup my phone's firmware in 2022, in case flashing goes wrong?
