Downgrade from 2ARF2.

---------- Post added at 10:55 PM ---------- Previous post was at 10:54 PM ----------

I'm still on v2
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Then it should work. Not wiping can cause you some issues but it should still work regardless. Flashing the non-HOME components will not wipe the userdata partition.
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
You on 2ARF2 and trying downgrade to a lower V2?

Try using the CSC it self, not the home CSC! Also try using 2ARF4 Odin files

What's the difference between U3ARG2 & U3ARG4?
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
I'm not sure anyone can tell. Too many are now trapped at 3ARG2 with no way to step up. The update zips were only 600k different in size. So it can't be much.

The carriers got 3ARG5 today. That one would be interesting to see, as well.
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
U3ARG2 is certified while U2ARG4 is un-certified. As to any difference not much, basically the same builds
[Samsung Galaxy S9+ Guides, News, & Discussion] yeltrah123:
Interesting indeed.
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
Actually 3ARG5 was on FOTA but no access to it, now they are testing 3ARG6

Hello All,

This may sound trvial to most but here is my situation:

I have a AT&T S9+ with version G965USQU2ARE6 and I want TMOBILE build with Wi-Fi Calling and VoLTE.

The plan is to use modified ODIN to:

1. Download and flash XAA_G965U1UES2ARF4_ODIN_Files.zip

2. Download and flash SM-G965USQS2ARF4.zip

Once I am done with this can someone tell me if:

1. Will I have TMO Wi-Fi Calling and VoLTE

2. Will this trip anything on the device to show if the device is using modified Firmware (I need to use MobileIron on my device for work)

3. Do I need to do Factory reset anywhere? and/or do I need to care about TMO userdata?

4. What (if anything) do I need to do for CSC?? (I should say I have no clue what this is...)

5. Can I just use device software update to keep the device updated?? I don't care about going to BL3.. I don't plan on messing with it after this ATT > TMO transformation

Is there a step-by-step somewhere ?
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
1. Yes, you will have both of those things, when done. However, you could stop at the step where you flash U1 and still have both of those things. T-Mobile is one of the carriers that allows Wi-Fi Calling on factory unlocked firmware, as well as VoLTE.

2. No. This is signed firmware, and will not affect the warranty or trip any flags that the device has been "tampered with."

3. Yes. When switching between and U and U1 firmware, a factory reset is required to get full functionality. As an example, when flipping from U1 to U, the VVM app will no longer be able to connect and retrieve messages (in my experience, at least). Clearing data and cache have no effect and a factory reset is required.

4. The CSC will happen on its own. Just leave your SIM card in the entire time and everything will take care of itself.
[Samsung Galaxy S9+ Guides, News, & Discussion] 3p4145:
Thank you!!!!!!!!!!!

I am stopping the U Firmware download.. sounds like its quite unnecessary for what I want to achieve.

Follow up question: Do I absolutely need to Perform a Factory reset when going from AT&T U to U1? (Serious pain to set everything back up :( )

Also: After I get on U1, Can I just use automatic SW updates or do I need to do the updates manually? (edited main post with same question)
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
You can attempt to not do a factory reset and see what, if anything, isn't working. In my experience, VVM would break. But T-Mobile has their own app in the Play Store for that functionality, so perhaps it will work anyway. No easy way to say without just trying. I recommend you specifically test the following functions:

- Send and receive a normal text using LTE/HSPA+

- Make and receive a normal call using LTE/HSPA+

- Enable Wi-Fi Calling, go to airplane mode, turn on Wi-Fi, and successfully complete a call. For extra credit do some testing with text while you're in that mode

- Ensure VoLTE is enabled in the menus and that calls still work as they should

- Get the T-Mobile VVM app and leave yourself a message. Ensure you get notified and can play the message

- Jump off Wi-Fi and make sure LTE/HSPA+ data works

If all of that works, I wouldn't reset. If you encounter any odd messages or errors, the first thing I would do is backup and reset.

How do you know?
[Samsung Galaxy S9+ Guides, News, & Discussion] hoaloaken114:
I'm using Roger now. My original firmware is 965W. I've flashed to U1 which I'm pretty happy since all the bloats are gone. But the wifi calling is gone as well. So is there any way to get back the wifi calling feature? Or the only way is to flash back the 965W firmware? Thank youView attachment 4553603
[Samsung Galaxy S9+ Guides, News, & Discussion] 3p4145:
Just to confirm... Everything seems to be working fine without a factory reset (Went from AT&T U to XXA U1 with TMO SIM inserted) (No RCS through)

Hello,

I went from AT&T to U1 using TMO SIM and everything seems to be working fine.. but LTE signal strength is a bit weeker.. Can someone explain to me the different between:

XAA_G965U1UES2ARF4_ODIN_Files.zip and TMO SM-G965USQS2ARF4.zip ?

Would going U build (on a U device) (from U1 build) help me with my signal strength issue?

---------- Post added at 10:55 PM ---------- Previous post was at 10:50 PM ----------

Actually the 965W firmware doesn't have any bloatware compared to the U firmware..

However you can use the XAC CSC for 965W while using Rogers and have all the features included Wifi calling etc with no bloatware...

What is your CSC code under service provider SW ver.? XAA/XAC/XAC?
[Samsung Galaxy S9+ Guides, News, & Discussion] hoaloaken114:
Could you tell how to enable the feature please?

3ARG5 is available, however it is U2ARF8 to 3ARG5...

[Samsung Galaxy S9+ Guides, News, & Discussion] S9Plus:
I just purchased a S9+ (unlocked from Samsung) and I'm on AT&T. I figured since my unlocked Pixel 2 XL had been receiving VoLTE while on AT&T, the S9+ (a phone actually sold at at&t) would also get it. Only after booting up and inserting my SIM did I see that was unfortunately not the case. My phone has updated to the latest unlocked firmware available. I've never had a Samsung phone before so Odin is new to me and I'm not quite sure what to do to get the latest AT&T firmware on my phone or where to get these files for the S9+. Can someone please assist me? Thank you very much!
[Samsung Galaxy S9+ Guides, News, & Discussion] macmane36:
I have a s9 plus ( Att version) on The ARE6 firmware and my phone will not receive the ARF4 OTA update from Att. Anyone know why? It keeps saying my phone is up to date.
[Samsung Galaxy S9+ Guides, News, & Discussion] macmane36:
Anyone ?
[Samsung Galaxy S9+ Guides, News, & Discussion] Venom0642:
Change the date and time in General settings and try again make sure you on a strong wifi signal.

---------- Post added at 08:26 PM ---------- Previous post was at 08:17 PM ----------

No wait scratch that, that won't work cause AT&T never released as a OTA ARE6 that was T-Mobile and they pulled that update. Update with this 2ARE6 to 2ARF4 https://androidfilehost.com/?fid=674106145207491978

Put in sdcard then turn phone off go into recovery and apply update from sdcard let do it's thing and it will reboot on it's own and update to AT&T Latest 2ARF4 .

That is why you won't get a OTA install above zip and then you will get OTA in the future.
[Samsung Galaxy S9+ Guides, News, & Discussion] macmane36:
Thanks but that didnt work either unfortunately

---------- Post added at 08:28 PM ---------- Previous post was at 08:27 PM ----------

O ok I'll try that

---------- Post added at 08:30 PM ---------- Previous post was at 08:28 PM ----------

But my thing is why wont my phone update OTA? Is it because I'm not on the original firmware that came with the phone I think ARB1 ?
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Right. OTA is patching from one version to another. That means the server has to have what you're on and what you're going to. In this case, it doesn't have what you're on, so it fails. At least that's my understanding, based on the leaked OTAs we have been getting.

Just flashing Odin with HOME_CSC would get you to ARF4, as well.
[Samsung Galaxy S9+ Guides, News, & Discussion] macmane36:
O ok that makes sense. So the only update this att phone has had officially was the ARB1 ? And the only way to get my OTA updates normal again is if I flash to ARF4 since its official from Att?
[Samsung Galaxy S9+ Guides, News, & Discussion] Venom0642:
The reason is like i said your on 2ARE6 that build won't give you OTA, since 1ARB1 was the one that give the OTA 2ARF4, so i linked you to the one you are on now 2ARE6 to up to 2ARF4 once you do that you will get OTA in the future.
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
Or use that OTA patch Venom linked a few minutes ago. That will get you there just as quickly. From that point forward, the OTA server should keep you up to date.
[Samsung Galaxy S9+ Guides, News, & Discussion] macmane36:
O I see now thanks I understand completely now

[Samsung Galaxy S9+ Guides, News, & Discussion] Trent54:
I tried flashing these all night last night, but I'm stuck on ARDA

I flashed my T-Mobile S9+ to G965USQ2ARDA in April because I thought the update would unlock call recording, and that might allow me to use my USB mic and headset for calls.

It didn't work, and since then, running software update to get current doesn't work either. Last night, I tried repeatedly to flash the U1 and the and US ARF4 firmwares linked here without success. Was using Odin 3.13.1, and also tried realbbb's "patched" Odin 3.13.1 without success. The files validated fine, would go to SetupConnection, then would say it was writing, then it would take a while but then say operations completed 0 success/1 fail

There was a SHA56 error too, that's why I tried the patched Odin. Fortunately my phone is not bricked, but the ARDA firmware is annoying. Thanks in advance to anyone that can help!
[Samsung Galaxy S9+ Guides, News, & Discussion] nugzo:
I know this sounds simple, but believe me it has helped a lot of people. Try a different cable and a different USB port, USB 2 preferably.. Maybe try on a different computer if that fails.

Any way to flash this without wiping. Dont want to have to call all my banks again for SS pay. Also any change log? 3ARG2 has been good to me. Thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] yeltrah123:
I flashed the update via SD card and my phone did not reset. My Samsung Pay app still has data saved and I didn't have to re-register my card. As for the U3ARG5 build itself, I noticed a slightly better performance with it, but for some reason my mobile data is a bit slightly worse performance but that could just be for the moment because everything else is working perfectly fine. I also notice some stock apps on the phone have been updated.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Hey all. I recently changed my Carrier from Verizon to TMobile and I was wondering if I could flash the TMobile firmware to get the TMobile boot animation and make my phone 100% TMobile except the Verizon branding on the back of the device? My model is SM-G965U and my current baseband is G965USQS2ARF4.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Yes, you can! You need to fully wipe and flash to the U1 firmware first, then flash to the TMB U firmware.
[Samsung Galaxy S9+ Guides, News, & Discussion] BigMosley:
Very nice, thanks for your quick reply. So it will 100% make my device a TMobile device except the Model number will remain and the branding on the back of he device? Is the TMB U firmware in this thread as well?
[Samsung Galaxy S9+ Guides, News, & Discussion] nugzo:
Thanks for info. What carrier are you using?
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
You should mention your carrier. In past updates, my ATT firmware device always wipes while others didn't. Even though they are all the same, the CSC apparently determines whether or not it wipes when flashing an update.zip

What carrier are you on though? It varies, or at least it did in earlier firmware versions.
[Samsung Galaxy S9+ Guides, News, & Discussion] xstefen:
The update zip literally wipes /data and /cache so you cant even say that.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Yes! The last tag in the three is not changeable currently. You will end up with TMB/TMB/VZN. There might be some links in this thread to the firmware you need. Personally, all of the firmware I have flashed recently have been from Updato. The site is slow to download, but I haven't had any issues with the firmware files.
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
As I mentioned in the post above, it depends on your carrier CSC. On ATT, it does wipe data. On at least one carrier (tmobile I believe) the same files werent in the past. Seems strange, but when I was trying some of the V2 bootloader updates a while back, it would wipe every time, but for others it wasn't.

Anyone on 3ARG2, Have you noticed your battery life a little worse since earlier firmware? If so, any better with 3ARG5? Now I see a good old 3ARG7 available. Maybe it's worth having to call the banks all over again ... Or wait and listen for feedback lol.

DAMN I miss good old HTC not being the top dog like they were back with the "ones" "desires" and "evos". I loved their phones. Unlock "your" bootloader through their site, flash away.

How do I flash this? (and all of the "upgrades") they seem to be kind of flashable zips and only the ARF4 has the Odin files...

I am on U1
[Samsung Galaxy S9+ Guides, News, & Discussion] CrazyApe18:
First use Odin to flash to U. You'll probably have to use normal CSC (not HOME), which will do a factory reset. Then put all those update zips on your SD card. Then load into recovery (Volume up + Bixby + Power) and select update from SD card. Pick the first, update and then do it again. It's quite a lengthy process now, because of all the update zips.

Hopefully we'll get new Odin builds soon.

P.S. Make sure to use Odin 3.13.1 3B patched version.
