[Help] - Samsung Galaxy S9+ Questions & Answers

Hello,
I currently have a AT&T factory unlocked G965U build R16NW.G965USQU3ARG7 on T-Mobile and I want to update to Pie. Yesterday I popped an activated AT&T SIM card to update the device to Pie and had no OTA luck. Can I download the latest version PPR1.180610.011.G965USQU3CSAB and install it via ODIN or do I need to do an incremental upgrade. I also tried updated to R16NW.G965USQS3ARG8 via SD card sideload and got an “error 7”, I do not care about the data on the phone. Should I only use ODIN or ADB? Also I can't seem to locate AT&T's version of Pie. If someone can guide me in the right path it would be great-full.

What I did for my ATT device, is changed the date to 22 Feb 2019 or a few weeks out, and then ran the OTA checker on the device and then it started downloading to update to pie. Either way, good luck and thread moved here...

Trouble Updating to 4.1 please Help

Hey Guys,
I've been trying over the last month to update to the new JB update and I think I've tried everything... I'm rooted, but I don't believe I'm unlocked (bought this 2nd hand back in March).
I'm currently on the IML74K.US_epad-9.4.2.28-20120525 build number. So I'm assuming I'm on the U.S. SKU (bought it in Canada).
Here's what I've tried based on posts:
1) Factory Reset, restore default build.prop and try firmware update via OTA.
No Luck
2) download update from Asus website unpack and put onto external SD card. Click update, the tablet resets, the Android guy shows up and eventually he goes dead (red exclamation). On reboot it says I downloaded the wrong version of the update package or something.
Anything else I should try?

Downgrade S9+ from 9.0 beta to 8.0

I have a verizon model SM-G965U (Snapdragon). A few weeks ago, I was able to follow this upgrade sequence to get Pie:
G965USQU3BRI9 to G965USQU3BRJ5
G965USQU3BRJ5 to G965USQU3ZRJ8
So now I am currently stuck on G965USQU3ZRJ8. I am attempting to upgrade it to the latest Pie release which is G965USQU3CRKD (November 19 2008). However, when I try to update the firmware via download mode / adb sideload update.zip, it fails because it expects the BRJ5 model.
So, my only option it seems to sideload the update is to first downgrade back down to BRJ5. How can I downgrade this firmware, or would it be easier to flash the latest updates via odin another way? I am clueless, please help a disgruntled user stuck in the wrong version of Pie.

You may install the required Android Oreo build first, and then update using ADB sideload to Pie.
This may help you - Download Galaxy S9 Pie.

That does not help at all. It simply repeats the steps I have already taken. If it were as easy as reversing these steps I would not post this topic. It was easy to upgrade, but downgrading is not as simple.
I already have Pie, I don't want vague upgrade instructions. I specifically want to go back to Oreo.
Use Odin to downgrade to Oreo. It's been covered many times in the beta thread. There should be a link in there for a lower version then you'll need to patch to BRJ5 and then the latest Beta.

Questions about how to manually upgrade my unlocked T-Mobile S9+ to the PIE manually.

OK, so I originally bought this S9+ from T-Mobile in the US, and I had it for two years, then I unlocked it, and switched to MetroPCS by T-Mobile, which really didn't need me to unlock it for that reason because the sim still would have worked as it's the same network. I joined the beta and am on the final beta build, and I've gotten these updates from T-Mobile still. However, today T-Mobile finally released the finished version of Pie, but tons of people on Reddit that weren't in Beta are getting it, but us in Beta aren't getting it.
I'm currently on G965USQU3ZRLG, and I want to downgrade back to what the version was before I joined Beta so I can get the update. I know I'm a senior member and have been on here for a while, but I haven't really done much phone modding in years, and I'm getting older -- which is coming with a **** memory, lol -- and I forget how to do a lot.
I can downgrade with Odin to the pre-Beta version without tripping Knox right? The whole point of me doing this is I assume at that point when I go into my settings and check for an update it will be available, because right now I have nada.
Any help is appreciated.
I am on the same boat as you. I have an unlocked AT&T S9+ on T-mobile, it will not get the update what so ever. From what I have been reading the phone will not push out a official OTA carrier update unless you have an activated SIM from the carrier the phone was pre-configured to. I'm guessing you can either sideload or Odin the latest rom but I've haven't found a website that host either AT&T or T-mobile roms.

I'm trying to find the firmware G965USQU3BRJ5 because I can downgrade to it in Odin, then I should be able to download the Pie update normally, but every ****ing site with that firmware for download has a slow download if you're a free member, which will take like a day, and for a fast download you have to pay to become a member -- even on Sammobile. I tried to find that firmware download on here but couldn't. Ugh.
My best advice is finding someone with at active Tmobile SIM card that you can borrow for a few hours and giving it a try.
Update: I used Odin to downgrade to the firmware before the OneUI beta, and my phone was decrtyped, and Odin successfully flashed the old firmware, but when I enter my password it verifies it to decrypt, but it stays on the decrypting Icon with the unlocked padlock icon and the circle going around it forever, it's been 40 minutes and it's still on that same screen. Any ideas on how to fix this?

My S9+ running Oreo claims it's up to date. Best method to manually update?

I just purchased a used AT&T SM-G965U. My carrier is Google Fi. It's running Android 8.0 and Samsung Experience 9.0. Build number is G965USQU3BRK1. Last security patch was November 1, 2018. When I try to update OTA or with Smart Switch both claim my phone is up to date.
I started looking into how I might manually update the phone and found some instructional pages for updating via ODIN, but was not able to find the correct firmware to update to Pie using that method. I did however find a thread on the XDA forums with a download link for an SM-G965U Pie build. Someone posted in that thread that it is possible to update the phone with a micro SD in recovery mode. Even with that being the case the firmware.science page linked in the thread specifically says that the firmware will update my phone from version G965USQS3BRK2 to version G965USQU3CSAB. This seems like a problem since my phone is running G965USQU3BRK1 which I assume is an older build based on the BRK1 designation. Will this update method even work with my phone? Do I need to update to BRK2 before I use the firmware linked in the thread? If so is the BRK2 firmware available for download anywhere? Or failing that is there an ODIN firmware update available?
Update: I tried updating via micro SD in recovery mode using a firmware update downloaded from firmware.science that is supposed to update my SM-G965U from version G965USQU3BRK1
to version G965USQU3CSA5. The update was aborted due to "unexpected contents". I transcribed the error at the bottom of this post. Not sure what else I can do if I can't find an ODIN firmware. If I used the modifed ODIN to flash my phone with U1 firmware would that enable updates through normal (OTA/Smart Switch) channels?
E3005: "EMMC://dev/block/bootdevice/by-name/modem:83300864:2d921fc2a30290a4f894ef4e5528ab83263913ec:84005376: 12c0577b202561c4a0732793bdbaf3a04eca67f0" has unexpected contents.
E:Error in /sideload/package.zip (Status 7)
Installation Aborted.#1
Update 2: I managed to find the ODIN firmware update files and successfully flashed my phone with a Pie build. Disregard this post.
I'm having the identical problem, only with Verizon SM-G965U. Android 8.0.0, last security update Nov 2018. Can someone guide me to the solution?
Thanks

What firmware are you currently on?
I've done a bit of research since I first posted this and think I know what's going on. This phone was supposedly new, unlocked. Then I found out SM-G965U is actually locked. It booted up with Verizon logo and worked on Verizon network, so I was ok with that. When I checked the firmware version, it was ....BRK1 (I don't have the phone in front of me), which I looked up to be Sprint firmware! This would explain why it doesn't get updates on Verizon's network, wouldn't it? How this came to be, I don't know, but I think I can proceed by getting a later Oreo or maybe Pie version for VZW and flashing it with Odin.
Comments, if any, are welcome.
If memory serves correctly if your firmware is a certain amount of revisions behind what is currently released then the OTA update and samsung switch will say your firmware is up to date. Even though it obviously is not up to date, it has something to do with how far behind in updates the phone is.
In which case you should be able to update your phone using the patched ODIN and the firmware files found on sammobile or via samfirm app. Thee files from sammobile or samfirm are not ones you can flash via SD card in the recovery menu, the OTA files and what are offered on sammobile or samfirm app (and from here unless otherwise specified) are two different things.
I would note that you might have to factory data reset your phone after flashing the new firmware. It's one possible result of flashing a newer firmware to a phone that has an older firmware like that installed.

New SM-G965U on VZW won't update -- Can I flash new stock firmware without rooting?

I got a new S9+ for my wife who does NOT want a rooted phone and all that that entails.
I was active in rooting many years ago, but have not strayed from the straight and narrow for some time.
I have a new unlocked SMG965U (not bought from Verizon) recently activated. It is Android 8.0.0, firmware .....BRK1 (I don't have the phone in front of me at the moment), last (and only) security patch dated Nov 1, 2018. I have noted from Verizon's web site they have moved up to pie, and have had quite a few security updates since that time. Looking for updates on the phone or through Smart Switch tells me the phone is up to date. There's a Verizon-Samsung utility that runs on PC for updating software that give an error message to the effect of "Firmware on phone does not support updating".
So, could someone point me in the right direction to determine, first, if it's possible to update the phone without rooting with stock firmware, and which guide I should use? Does Odin require a rooted phone, or is it simply a matter of me locating the proper update and following Odin directions?
Thanks
Odin does not require root and yes just need the correct update Sam mobile has all the latest files you need to use odin I would go there for what you need
