Hey guys, I rootrd my phone about a week ago and installed Pie rom. However is it possible to get my previous original android and unroot my phone to be like I bought it?
Thanks!
Yes, if you download the stock firmware files from a firmware host (updato.com, sammobile.com) or from samfirmtool, then do a full flash with Odin, it will essentially be like it was factory new.
However the exception is the knox trigger, once tripped it can never be reversed.
Downgrading may require bootloader unlock and a custom version of Odin, otherwise you could flash an older firmware with TWRP to downgrade then reflash with Odin

I rooted my phone, but had some problems, so I unrooted the phone back to stock 4.4.2 I checked that my phone was unrooted through root checker, and it is, but I can't update to 4.4.4 because it is still detecting that I have messed with my phone
You need to flash the NK4 stock tar. You should be to find it on sammobile.com. If you have altered your system files or deleted things that the update file is trying to upgrade the update will fail. But if you flash the stock tar file with odin it will return you to stock and upgrade you to 4.4.4 all in one. Bonus is, you won't lose any data.
Hi,
I have a G920F, I was rooted and want to go to stock again. I have restored the device with Smart Switch, but now I am unable to flash any other rom. I have downloaded 3 different roms from Sammobile and get sw. check failed device 3 binary 2 at everyone. The current rom is form Italy Wind the latest OI9. Any suggestions?
Thanks in advance.
Hi, probably you trying to install oldest firmware 5.0.1, download the latest firmware and try again. You are with 5.1, right? This error on odin happens, because you cannot downgrade the firmware. Hope this helps.
I think you can not downgrade even if it is the same Android version.
If it detects you are on a newer bootloader it will give you that error.
What I belive you can do is to extract the bootloader (sboot) and modem from the .tar file and flash ONLY the system through Odin.
Don't know exactly how to do that because I haven't done it but I think that would do; you will have to search and read my friend.
You will have the stock firmware but with latest bootloader and modem.
Hope this helps.
Note: As far as I know this will work if its the same Andorid version; you can not have Android 5.0.2 with 5.1.1 bootloader.

Hi,
I have tried what you said, but no succes. The firmware was already recovered with smart switch so the bootloader is the latest.

But did you try to flash without the bootloader and modem?
So my friend has an S6, it's the international 920f model and it's currently on a rooted 5.0.1 with TWRP flashed. I'm not really anywhere near him, and he has no PC to flash it to stock with Odin like normal. Is there anyway he can flash it all to stock on the phone itself and then being able to update to 6.0.1 via ota?
Hello,
I rooted my s5 way back when it first came out but I haven't upgraded the firmware at all. From what I remember I had trouble installing a custom recovery so the phone is only rooted. I would like to bring it up to the most current version of android. What's the easiest way to do that? I'm on baseband version G900PVPUIAND2.
Thanks in advance.
Edit: I found this https://forum.xda-developers.com/showthread.php?t=2742994 which had a link to the stock factory image but sammobile doesn't seem to be hosting it anymore. Is there another reliable place that I can get it? Or would just doing a factory reset of my phone make it so I can start taking OTA's again?
The latest stock firmware for G900V is Marshmallow QC1. You can download it here and use ODIN to flash it:

If you want to root it you can use CF-Autoroot in ODIN. This will trip Knox if not already tripped (but probably doesn't matter on an older phone like this).

If you want to install TWRP you can use ODIN again:

Good luck.
I was running on Superman rom(superstock kernel)
i tried to reboot while suddenly couldnt do so coz custom binary frp was locked.
I tried to flash stock firmware(did not download it from Sammobile and it was a nougat firmware)FAILED
Note: Rooted the phone months ago when it was on oreo
What could be the reason for the fail? is it because I tried to install a older firmware?
Please reply at the earliest
Thanks in advance!
Oreo firmware seems to be detecting custom firmware and would FRP locked the bootloader and the only way to fix it is to get to download mode and flash stock firmware with odin.
