Official 9 Pie is up! - for the U model!

Can be gotten from SamFirm using Region CCT (Xfinity Mobile). Anyone can flash it though - doesn't matter what carrier you're using or which carrier the phone is originally from.

Happy flashing!
[Samsung Galaxy S9+ Guides, News, & Discussion] ChadH42:
Be careful... I flashed this on my 9+ unlocked device (U1) and now the phone won't connect to the mobile network or make calls!!
[Samsung Galaxy S9+ Guides, News, & Discussion] YrrchSebor:
I was sort of wondering about problems like this. Did you just use HOME_CSC? I would guess that flashing CSC and letting the phone wipe itself would work.
[Samsung Galaxy S9+ Guides, News, & Discussion] ChadH42:
Yes, I used home.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
That is why you have issues with your flash then. You should never use the HOME_CSC when cross-flashung. Flash it all again and use the non-HOME_CSC.
[Samsung Galaxy S9+ Guides, News, & Discussion] hoaloaken114:
A stupid question but can some one enlighten me with what is HOME_CSC and what's non-HOME_CSC?
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
There are two files that are CSC's and can go in the CSC file for ODIN. The HOME_CSC is used for preserving data when updating to a newer version of fbe same firmware. When flashing fo or from the U1, there is another CSC file that will wipe the data needed to match the new radio, bands, firmware version, settings, APN, carrier aggregation, add and or remo e bloat, and so on.
[Samsung Galaxy S9+ Guides, News, & Discussion] mopartonyg:
The post you quoted says for the U model not unlockedU1. Be careful.
[Samsung Galaxy S9+ Guides, News, & Discussion] ChadH42:
Sorry, I forgot to mention that my u1 had been previously flashed with the U model firmware before I flashed the CCT files.

BTW... a factory reset fixed my problem.
[Samsung Galaxy S9+ Guides, News, & Discussion] mopartonyg:
Great glad you got it straightened out.

Currently I'm on Android Pie on an S9+ U1 (flashed to U/TMB).

Can someone explain the differences if I go back to U1/XAA and U1/TMB?

XAA would be no bloat I assume

TMB would still keep me unlocked with TMB features?

Thanks!
[Samsung Galaxy S9+ Guides, News, & Discussion] YrrchSebor:
I've been kind of wondering about those different U1 firmwares myself. I've been flashing strictly XAA, and I'm using a T-Mobile SIM, and my CSC always shows up as TMB/TMB/VZW. (The VZW only indicates that my phone was originally a Verizon device). I believe that the U1 firmware sets up the phone according to the SIM and maybe even changes the CSC to TMB(?). I really don't know if there's any difference if you choose a U1 firmware that says USA TMobile. Hopefully somebody here knows more..
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
My phone shows TMB/TMB/XAA <---- XAA = Unlocked. If yours shows VZW, did you get a fully unlocked (U1) direct from Samsung?

Before, I only had 1 option. XAA. I do know using the XAA version and the TMB sim, it worked, but I lacked HD calling, wifi calling and video calling.

I purchased mine direct from Samsung and unlocked. So it's SM-G965U1 (aka XAA). I just can't figure out what the difference is with the TMB version.

I wonder if the U1 TMB gets the pie updates the same as the U1 XAA.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
There is no official TMB U1. There is a TMB U. The U1 is a non-carrier generic firmware that comes on devices sold directly from Samaung and retailers carrying unlocked non-carrier specific devices. All carrier specific official firmware for US carriers are U firmware.
[Samsung Galaxy S9+ Guides, News, & Discussion] YrrchSebor:
I got my phone on eBay, thought I was ordering a U1 but it was a U from Verizon, but the seller had unlocked it. Then I flashed U1 XAA, and after the flash and full wipe my phone rebooted and set up according to my T-Mobile SIM. I have Wi-Fi calling, volte, free caller ID (a super cool U1 feature ?), but no video calling.

But yes, when perusing the different U1 firmwares, I see a bunch that are labeled with U.S. carriers, but so far I've only chosen the XAA ones. The carrier labeled ones are a mystery to me.
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
Then explain this: "G965U1UEU3ARK5_G965U1OYM3ARK5_TMB.zip". That's U1/TMB

https://www.sammobile.com/firmwares/galaxy-s9-plus/SM-G965U1/TMB/
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
That is not an official firmware!
[Samsung Galaxy S9+ Guides, News, & Discussion] YrrchSebor:
Yeah on samfirmware they have U1 that are labeled with all different US carriers and I'm not sure what they are. I wonder if it's just U1 firmware that's already set up for those carriers or something?
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
So stick to U1/XAA?
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Yes. The one you linked is a combination firmware. The U1 base with the TMB U CSC. Personally, I always try to stick to the official firmware, especially of you want OTA updates to work.
[Samsung Galaxy S9+ Guides, News, & Discussion] YrrchSebor:
A bunch like these. I also see Verizon, Sprint, etc..

[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
So I flashed my SM-G965U1 (Unlocked S9+) to the U firmware. I'm currently on G965USQU3ZRLG (Pie Beta 4) and I can't flash it back to U1/XAA "G965U1UEU3ARK5" in Odin. What am I missing?

Don't know if any of this helps. It looks like in Recovery mode it's v1 bootloader? But I was able to downgrade to U version of Android 8 via Samsung Smart Switch. Still can't switch back from the U to my U1 though.
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
Tried from SD card.
[Samsung Galaxy S9+ Guides, News, & Discussion] Cyclone Emperor:
Jcsww posted this. I hope it helps.

There are two files that are CSC's and can go in the CSC file for ODIN. The HOME_CSC is used for preserving data when updating to a newer version of fbe same firmware. When flashing to or from the U1, there is another CSC file that will wipe the data needed to match the new radio, bands, firmware version, settings, APN, carrier aggregation, add and or remo e bloat, and so on
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
I tried both. Neither worked. It wouldn't even attempt to write. Only sit there and timeout and fail.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Are you using the modded or patched ODIN? Do you have USB Debugging enabled in Developer Options? Are you using the original USB cable that came with your device and using it in a USB 2.0 port?
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
Odin v3.13

Yes

I used USB C, and 4 factory cables.

If you look at my images, it shows all the info. I don't want to root it to go back to U1 but I can't find solid info when you go from U1 > U (did that easily) and then U > U1 (that's my issue atm).

Getting a "FAIL! SHA256 is invalid." and all the files are valid.
[Samsung Galaxy S9+ Guides, News, & Discussion] bkores:
You have to use the modded Odin here: https://xdaforums.com/android/software/patched-odin-3-13-1-t3762572

Also you have to flash CSC (not HOME_CSC) when switching from U to U1 firmware and vice versa.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
What did younuse to extract the image? Windows ZIP has corrupted files on people without notifying them. Try using 7ZIP or WinRAR to extract the image and downloading it again as well.

The process for flash to the U1 from a U or W fireare is almost exactly the same to go from U1 to U or W. You don't use the HOME_CSC but donuse the other CSC and flashing to a U also has a separate userdata that should also be flashed.
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
Using that version. "setup connection...." shows and it 100% fails. I tried 9 firmwares. People stating the cable is the issue = false. I just removed another never used S9+ cable from the actual U1 box. Fail. I am getting a "Complete(write) operation failed." or "FAIL! SHA256 is invalid.

It's not the data cable. I'm trying on 3 computers, switched between 20 cables since last night (yes, all factory cables), and used EVERY Odin and U1 firmware.

I never used home_csc. What userdata should I be flashing? I'm going from a U1/XAA > U/TMB (successful), and trying to get the U/TMB back to U1/XAA. XAA has NO userdata. I use Winrar. I'm also a Network Engineer so I'm not clueless on CRC checking.

It's not as easy as it seems to go from a U (really a U1 phone) /TMB back to U1/XAA for some reason.

[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
I have flashed my W to U1, TMB U, and then back to the U1 without any issues. The U1 firmware doesn't contain a separate userdata file to flash so that slot stays empty.
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
This is why I'm perplexed buddy!

I've done this before and never had an issue. I finally pulled the Odin and firmwares off my old M.2 drive and currently am coping it to my NAS drive. Once that is done, I'll post the current Android 8.0 I'm on now (I think it's Samsung Experience 9.0 though) and see if we can figure what I'm doing wrong. I'm computer literate but when it comes to this....... I've only done it a few times. I'll try to get all the info and then see what you guys suggest. I truly appreciate the help. If I need to root it, NOT a concern. Give me a bit to get it all moved and stop swearing at this darn phone.

The good news is that nobody can call me so it's been peaceful. :laugh:
[Samsung Galaxy S9+ Guides, News, & Discussion] bkores:
Try using a USB 2.0 port and not USB-C or USB 3.0. Also try running Odin as administrator.
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
Did 20 times. Failed

See attached image. Let me get all the info. And I'll reply and go from there.
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
This is installed. Updating to ZRKJ then what do I need to do? First image shows all relevant info. 2nd is what the update is doing.

Just need the steps to switch back to U1.

Now it's updated to ZRKP, then ZRLG. What's confusing is that's only on the U1 model on firmware.science. The U model only has BRK2/CSAB. WTF?
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
So I am totally clueless. But after REMOVING myself from Android Pie beta program.

I was able to flash this: C:\Users\Rick\Downloads\S9+\U1\G965U1_RH7\G965U1_RH7_3

So I assume I can work my way back up. I pulled it off my NAS and tried it on all the other servers/laptops and desktops but the only difference is unregistering from the beta. Oddly It still was pushing U1 updates marked as U. I'll know shortly once I set it up and restore the data.
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
Next question. I removed the sim card before flashing it back from the U to U1 (it is a factory U1) and it's still showing Tmobile (It's a U1/XAA) so I assume I need to factory wipe it after I get it up to the newest 8.0 version I want?

Finally, just wait for Samsung to push Pie update?
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
The U1 firmware should adapt to whatever SIM is in thw device during the setup. If that is a T-Mobile SIM, then it will show TMB/TMB/XAA.
[Samsung Galaxy S9+ Guides, News, & Discussion] YrrchSebor:
Glad you got back to U1. I think you probably want it to show T-Mobile so that the U1 firmware will be configured to give you Wi-Fi calling and volte thru Tmo. Once you factory reset and have your sim card in it will probably reboot and configure that, at least that's what happened when I flashed to U1 using CSC for a full wipe. My CSC shows no XAA at all even though that's the firmware I used.
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
l'm glad too! Thanks!

I know for a fact, the second I put the T-Mobile sim in, I'll get wifi and volte, I just lose video calling. My concern is with PIE and Q, they have ways to carrier lock features more as opposed to U1 models which I read about on many sites. Hence why it was imperative I returned it back. Not to mention when I upgrade, I wanted the U1 firmware on it or Samsung could give me crap for it when I trade-up to the S10+ 5g model.

My biggest question now: I'm on G965U1UEU3ARK5, but on firmware.science I see: Current version: G965U1UEU3ARJ2 , upgrade to: G965U1UEU3ZRK9. I assume since I'm past ARJ2 I can't use that update file? I'd like to get on PIE asap, but I wanted to know if it's safe to still pull the ZRK9 or just wait?
[Samsung Galaxy S9+ Guides, News, & Discussion] YrrchSebor:
Yeah from what I've read you would need to Odin back to ARJ2 in order to install the pie updates. On SamMobile I actually found ARL1 for XAA, which has the December security update and seems to be the very latest official for U1. For some reason it didn't come OTA to my phone when I was on ARK5. Personally I'm just going to wait until official pie for the U1 comes out and then I'll probably Odin it.
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
If I odin to ARJ2, is G965U1UEU3ZRK9 Pie or still 8? Got a link to the pie update from ARJ2? I don't want to use a non U1 firmware (ie: F model).

SamMobile has ARJ2. So if I push that via Odin, then: SS-G965U1UEU3ARJ2-to-EU3ZRK9-UP.zip via sdcard, I should be on pie?
[Samsung Galaxy S9+ Guides, News, & Discussion] YrrchSebor:
Yes I believe ZRK9 is Pie beta and there are a series of pie beta updates you can flash from there. Check this thread if you haven't already: https://xdaforums.com/galaxy-s9-plus/how-to/official-pie-beta-ota-files-factory-t3868977
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
Thanks for your help! Now to wait 4 hours for ARJ2 to download, and I'll push that, then flash it to Pie beta. You rock!
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
U is only going to show from BRK2 until tmo releases pie. Since the only carrier doing the beta for the U is tmo, there's no upgrade path until they actually upgrade. Comcast pushed pie from BRK2.

[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
Y are u on this build?
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
1. Because I am about to upgrade and send it back to Samsung.

2. Because Pie and Q have more restrictions on a locked model and I purchased unlocked direct from Samsung.

3. Because I will get OTA just as fast if not faster than most carriers.

4. I only lost video calling on my carrier and it's only supported with people on the same network. So no point to keep it on the U/TMB fw.
[Samsung Galaxy S9+ Guides, News, & Discussion] bkores:
Actually the unlocked model gets updates slower than the carrier models. Expect the unlocked Pie update to be released 2-3 weeks after all the carriers. Just to let you know.
[Samsung Galaxy S9+ Guides, News, & Discussion] Ranger187:
Not 100% true. But in any event, irrelevant.
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
He is actually right. U models get updates faster than U1
[Samsung Galaxy S9+ Guides, News, & Discussion] YrrchSebor:
BTW, has anybody on the U1 firmware, ARL1 noticed that default apps don't stick.... when asked if you want to use an app by default for a certain action, even if you choose 'always' it still asks every single time.

Hi All,

been a while. I just purchased a Verizon s9 that i want to convert to a Canadian firmware. Im familiar with the carrier switch steps of the S8+. Im trying to conver my VZW s9 to canadian fw.

i already have the combination file for the s9 and the W firmware. Could someone please guide me to the correct steps. Looks like the steps of flashing the factory binary, then Canadian home CSC etc dont apply to the s9?
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Flash to the U1 firmware, then flash to the W firmware with the modded or patched ODIN. Do not use the HOME_CSC while flashing either firmware or it will mess up the conversion.
[Samsung Galaxy S9+ Guides, News, & Discussion] alirz:
Thanks. but then how i change the CSC? on the s8, we would boot in the factory bin and then echo the correct csc in the file system. does this straight flash process take care of that?
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
The firmware zips include the CSC's. You load and flash the 4 files in the U1 firmware. Then do the same with the W. I can't remember if there is a userdata with the W. If there is, flash that with the other 4 files.
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
US CSCs aren't going to be present in Canadian firmware. So you shouldn't have to worry about it. Personally, I don't even think the U1 flash is needed. All W firmwares should have all Canadian CSCs included already
[Samsung Galaxy S9+ Guides, News, & Discussion] alirz:
So why did the S8 had such a crazy carrier switch process in order to the the correct CSCs? What your 3 folks above are saying, that makes it sound wayyyy too straight forward. Im not saying that your all are incorrect, but has one of you actually done a carrier switch/actual CSC change on the s9?

FYI: S8 carrier switch process: https://xdaforums.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
1. I stopped reading that link after the part that says that the 3 characters of the CSC are visible at the bottom of the Recovery screen on an S8 - because they're not. Samsung stopped that with the S8, and most devices that I've seen for the past 2 years don't show it either. So I doubt that poster had any idea what he's talking about - and his post looks about 100x as long and complicated and difficult as firmware switching actually needs to be.

2. This thread is only about U models. I'm sure plenty of people in the thread have done switches on a U model S9. Can't say the same for a W model. You'll either need to find a thread on the W model, or just try it and see what happens
[Samsung Galaxy S9+ Guides, News, & Discussion] alirz:
Actually the CSC code does show at the recovery screen! i have done that carrier switch process many many times on the s8! and so did many others. the S8 community is a lot bigger than the s9 i think.

Anyways, i have so far flashed U1 and then U. I will verify what csc is running after booting with the sim card in the phone. thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
1. I have *never* seen a specific CSC referenced on the Recovery screen of an S8. What I've always seen it say is "Successfully applied multi-code CSC".

2. If you wanted W firmware, why would you flash U firmware...?
[Samsung Galaxy S9+ Guides, News, & Discussion] alirz:
some threads that i read and also what one of the poster mentioned above. It seemed like the process to get to a W firmware involved going from U to U1 and then to W. I just got the s9 today so im not familiar with its flashing process. Hence i came here for help therefore i took that persons adivce. Its possible going to U1 was not required.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Some say it is, others say itbisn't. Oersonally, flashing to the U1 first is better to be safe and have it all work than to have to do it all over again the right way.

I have personally flashed over a dozen S9 Plus devices and muktiple times. The same goes for the Note 8 and Note 9. All three have the exact same flashing process.
[Samsung Galaxy S9+ Guides, News, & Discussion] alirz:
well, as i had expected this is what i see under my software information on the phone under the server provide info: VTR/VTR/VZM. Which from my experience with the s8 carrier switching is incorrect.

This tells me that my "carrier fw CSC" is still VZW" where as the other two have changed over to the Canadian csc VTR. This is where that step of booting into the factory binary and writing the firmware csc use to come into play. but i cannot find the steps to do that on the s9. The steps from the s8 dont seem to work.

In a properly flashed firmware, at least on the Canadian fw, i should not even see ANY CSC codes under the software info. These only show up there when MIXED CSCs are installed.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
No! The last of the three tags is where the device was pur hased, which can not be changed.
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
And by "VZM", I'm assuming you mean "VZW"...?

Incorrect. Yes, it can be changed
[Samsung Galaxy S9+ Guides, News, & Discussion] alirz:
Correct. I meant to say VZW.

And as for changing that CSC also, I was also under the impression it could be changed, at least on the s8. However I'm in able to find any steps/guide to do it on the so.

Would you happen to know? Would really appreciate it.thanks.
[Samsung Galaxy S9+ Guides, News, & Discussion] bkores:
No it cannot. It's the original carrier's CSC (or XAA if the device is an Unlocked model) . If you for example purchased a Verizon Galaxy S9 and then switched to T-Mobile, the CSC would be TMB/TMB/VZW. If you purchased an unlocked Galaxy S9, and then put in a T-Mobile SIM, the CSC would be TMB/TMB/XAA.

In my case, I purchased a T-Mobile Galaxy S9 and then flashed the unlocked firmware, so my CSC is TMB/TMB/TMB and not TMB/TMB/XAA like it would be if I purchased an unlocked Galaxy S9.
