It's not possible. Your current bootloader version is U5, and Pie only goes up to U3. You can't go from U5 to U3.

There's an answer to this in the Verizon Note 5 thread. Just use the AT&T firmware instead of for the Verizon firmware.

Which firmware did you try to use because you can only go back so far.. Like you can't go from Nougat all the way back to MM 5.0.1 because of the locked bootloaders! Try downloading and using this firmware.. After it's downloaded extract the file 1 time so you get a .md5 file that odin can use.. The link is below.
Download this firmware and try.

It's not possible right now to go back that far.. Nothing can be done until the bootloaders get unlocked.

Yes it is passable. You need to find at last firmware with baseband N920AUCS4CPK1. One did you try to flash did not work because it was bootloader version 3 and since you are on android v 7.0 your bootloader is v4. Look for firmware where after S or U you see 4. In example N920AUCS3BPH4 you got 3, this mean bootloader is v3.
Good luck

if you want a clean install first install Nougat BL AP CP CSC of your device. After first boot on the settings screen, shutdown the device and go into bootloader mode, select AP from OREO, no other one, only AP. Press start and you A320FL will be upgrade to OREO. I installed Russia Oreo on A320Y
Sorry for my bad english

First flash clean nougat and use nougat fles only. When it boot first time where you start putting settings language etc. Shut down and flash only oreo AP file-> done
Its reset your phone...
CSC Oreo will get error of pit file wrong. BL Oreo will get error of Bootloader wrong. CP Oreo will get error of modem wrong. AP Oreo only contain upgrade files, this file is the correct to upgrade. Now, if you want a clean install, first flash Nougat and then flash only AP file from Russia Oreo, other ones files (BL, CP, CSC) are get error because not corresponding to device

Flashing an official stock ROM (with Odin) should never trip Knox. At least it never happened to me with other Samsung phones (Galaxy Ace, Galaxy S3 Mini, Galaxy Alpha). I haven't tried with this one, but I bet it will be safe.
hello guys

OK I have officially screwed up...
So it was all going smoothly flashing a tweaked custom rom and twrp successfully and then I decided to back to stock...
I accidentally (ok maybe not so accidentally) flipped the OEM unlock switch and now I am locked out of my phone since I still had the custom binary on the phone.
I tried to flash the latest stock firmware for the s9 BTU found from samfirm but odin seemed to have not liked the firmware or something and it gave me an a red message on the odin mode screen.
When I try to flash everything at once I get "REV Failed Check (Bootloader)"
When I try to flash just AP I get "REV Failed Check (Kernel)"
At the moment when I boot up I get the message telling me to use emergency software recovery but Smart Switch does not seem to recognise the device either in the emergency recovery page however it does try to connect on the home page.
I'm not too sure what to do, any help would be nice?
Thank you
You cannot downgrade the bootloader, check which version your phone has in Download mode (BL: xx) and check which version the firmware you are flashing has G960FXXU1BRF8

OK I think I have found the BL version from the line that says...
"RP SWREV B:2 K:2 S:2"
But what firmware has the BL Version 2? They all seem to have a BL version of 1 from what you've said?
If there are no firmware which match this, what do I do? Is my phone redundant?

I saw on another thread that was replied to about the Hong Kong version having been already upgraded to BL 2 so I am going to give flashing that a go and I will report back.

Yea you'll either have to do something like that, or wait for your region firmware to have it's BL updated
Tried it out with a BL2 BTU firmware from SamMobile and the flash went smoothly however now I'm stuck in a bootloop when I'm trying to boot up.
I know this could be anything but I can't get any form of logs as the only mode I have is Odin mode available to me...
The way I flashed it was by doing BL first followed by AP, CP then CSC separately with auto reboot and one other one checked that was instructed by SamMobile. I tried to do them together but I keep getting an error of not being able to read a line.
What should my next step be?
What could be the reason for this bootloop as according to Odin the flash went well?
Thanks in advance

You might need to check "Repartition" in ODIN only, flash all 4 parts at the same time, use CSC and not HOME_CSC
Make sure you are using ODIN 3.13.1
Oh yea forgot the update...
I got it working, I think I unchecked repartition and auto reboot whilst flashing all of them together to get it working
So yea this is now solved
I have a Samsung A7 2017 (SM-A720F) brought from UAE having latest Oreo update. While I tried to flash an INS version over this Odin detects the phone. But after hitting start it takes some time and gives error like failed. I also tried to root it with CF-AutoRoot file. Those also have the same error. Developer mode, USB debugging and OEM unlock are ON. Trying with windows 10 + Odin 3.13 (latest). Any solution ?
Combination file successfully flashed. But, still not able to flash another country File. Can I proceed with original country file (i.e XSG stock firmware) ?
Please help me

Root with twrp and magisk, cfautoroot is OG in my opinion . Try flashing just CSC_home or whatever it is called in Odin.

When you flash twrp, untick auto reboot in odin. Boot straight into twrp without booting system.

It won't help change the csc. But hadesrom oneui has a huge selection of csc's you can select when flashing it.

If I flashed HadesROM OneUI with 'INS' CSC can I able to downgrade it with INS Stock firmware in future ?
Is the binary thing really need to consider while flashing that ?
PS : I looked on HadesROM. It is temptating. But, the real problem is with VoLTE which affects the network badly here... The VoLTE only network is a large mess here... And thanks for your unconditional Help & Support :fingers-crossed:

It should work to change csc with Hades and then flash stock. Just make sure you don't reflash csc then because it could change.
