[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] bradical711:
Well I searched you up and I found your supposed questions....

"So I rooted my S8+ back in October and I want the latest Android update from Samsung. I don't really care for the root anymore. I just have a couple questions. If I update my phone with the latest Samsung update while rooted, will I run into any issues? Or will it install as normal and just be unrooted in the process? Also, is there anyway I can install it without wiping the phone? I rather not reinstall everything again..."

And then I found this...

"

I'm ok with that. Do you know where I can download the stock firmware? Samsung's website won't let me download Smartswitch for some reason and some of the websites I've found online either charge for "premium" downloading or doesn't have much of a reputation."

And finally...

"I managed to get pass that error by using ComseyOdin. I'm still on 7.0 after trying to flash Oreo, not sure why. Trying to flash stock 7.0 now to see if I can upgrade that way.

Edt: I flashed stock from Updato but it says "The Operating System on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center." And since my battery power will not go above 80% I think its safe to assume all that happened was my device getting wiped and still on SamPWND...

What can I do? I have several apps that will not work on 7.0 anymore, making root just not worth it now. How can I get back to stock and receive normal updates?"

So judging by these statements/questions alone, you have not been flashing for "near 10 years now"...:confused::rolleyes:

You can tell by the way you ask these questions. Asking if you can install updates while being rooted is just plain silly.... That's a first rodeo type question my friend and I suggest you better hop off your high horse like you know everything about flashing.... Because if you did, you wouldn't be coming here to this thread asking for help about flashing.. make sense? Because if not I don't have to help you and you can waste your money on a new phone or get help from someone else. So lets continue shall we? Anyways my next guess would be are you using the latest Odin? If so what's the latest version so I can confirm. Also it's impossible to stay rooted after flashing a new nonrooted AP or system. Reason being is because when you flash a new system in this case the "AP" section in Odin AND you selected the right settings when flashing, your "rooted system" gets replaced/wiped entirely and it is replaced with the stock firmware you are flashing along with all the other parts like CSC which is your carrier settings and the BL which is bootloader and CP which is modem related. ALSO, if your system and everything else was "still rooted" after set up, you must be flashing 7.0 firmware of some form because if you were flashing Oreo with the latest odin, well it's impossible to root Oreo therefore that outcome of you being rooted wouldn't be a possibility. AT ALL. So maybe try flashing Oreo instead of nougat? Also what device do you have? Model? Firmware you had prior to flashing? BL revision? Do you know any of that? Because that would be super helpful in me trying to help you. Also if I could get the specific errors from regular Odin when flashing Oreo that would be appreciated. Also are you using USB 2.0 or 3.0 when flashing? You should be using USB 2.0. Have you reinstalled your Samsung drivers for Odin? There's so many variables and I need some help to lower them so we can get to the problem.

ALSO if your system is still rooted after flashing then you must be flashing the rooted system or "AP" section on top of stock BL CSC and CP instead of the stock AP. Literally no other combination would end up with you still on a rooted system so you have to be doing something wrong. You're either not checking a box in Odin having to do with wiping your system because you don't want to restore anything or something.
