I really need help...Custom ROM stuff issue

I have a problem

I just got a Samsung galaxy S6...and i'm pretty sure it isn't a clone...it functionins almost perfectly

The problem is...whe i access the download mode...my system status and cureent Binary are all 'CUSTOM'...whic makes me think a Custom ROM is installed on the phone
Apps like root checker and es explorer clearly tell me my phone isn't rooted
The thing is i can't access software update and i receive an error messge when i try to use smart view on my tv...and i'm prety sure this would be solved if my status and curent Binary said 'OFFICIAL'
I really need help...I don't have a laptop so it would be cool if i could solve this without having to root my phone
Could someone help me make those status official ?
Thanks

HI Okalla-

So we can better serve, can you send me some information that's found under 'about phone' in system settings?

What we need here, is the build number and version OS.

I can take it from there and get you a definitive answer.

I've included a screenshot of an old custom build for reference.

Hope you'll help

Hmm.. checked a couple of resources and have included a couple of links to confirm for yourself, but it looks like you are NOW running stock.

However, since you are seeing the 'custom' message on boot, it is possible that at one time the phone had been rooted, then flashed back to stock without clearing the custom flag. -- pretty common

Can you describe in detail the error msg you're seeing?

Thanks a lot for thz links on the updates...but i really want to remove those custom flags as you say...like i said i can't smart view with my tv and i'm sure that's the reason

Can you help me for this?

I sure can. Depending on how much skin in the game you're willing to put into the effort, we can have the S6 up and running as it was when it left the factory.

Good...then do p'ease...what i might lack might be the elements ..like I don't have a laptop

Just hope a laptop won't be needed

Concerning the error message upon update trial...the software update button doesn't do anything.It's as if it is useless...like just there for design

Download stock firmware and flash it. Then it'll say official if Knox has been tripped no big deal it'll update tripped or not.

Stock firmare?...please can u be more explicit?
 
#11 okaliadaniel, Aug 12, 2017
You would need a laptop/desktop in order to flash firmware.
 
#12 James L, Aug 13, 2017
Well...i could get one...but it won't be real good
 
#13 okaliadaniel, Aug 13, 2017
As long as the PC is able to boot up, install drivers and connect to the device it'll be fine.
 
#14 James L, Aug 13, 2017
Okay...what am i meant to do
 
#15 okaliadaniel, Aug 13, 2017
Let's make things little more clearer for you. Now custom ROMs are cool to use sometimes but might trouble you if you did not read what the developer said. A custom ROM changes the part of your system that you know about entirely and may or may not be rooted. Samsung does not like it's users to do any changes to their software so it won't let you update after your device is rooted. Your device might not update also because updating a Custom ROM by a stock ROM might create problems because they are differently coded.
First tell us about your model number.

Do i connect the phonz to the pc before or after going into download mode

First connect and then enter download mode. If that doesn't work then enter download mode first then connect the phone.
Improper connection with the PC can be shown with an error but if you disturb the connection while flashing you might get into trouble. For reference you could see a few videos on the net by searching for "Flash stock ROM Samsung Galaxy S6" or any phrase similar to that.
