Yeah. You can go straight to the VZN U firmware then. Still make sure you factory reset before flashing unless you literally just took it out of the box and haven't set it up yet.

How to enable wifi calling?

I have an S9+ att unlocked with a tmobile sim in wondering if by flashing this the wifi calling Wil be enabled?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
T-Mobile's WiFi Calling will work on the U1 and the TMB U firmware.

ok my english is not my primary language so i will ask this and probably is already answered lol....i have a sprint s9 plus that is now unlocked and everything works fine with my att and tmobile carrier...but i dont want the sprint stuff so can i flash a U1 unbranded firmware even if the bootloader is diferent?? my firmware now is 3ARG2 so i see the U1 is bootloader 1 or 2 so can i flash it????
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
The bootloader version must be equal to or newer than the bootloader currently on your device. You can not flash an earlier version of the bootloader successfully.
[Samsung Galaxy S9  Guides, News, & Discussion] denpad2010:
OK thanks so no U1 firmware for my sprint S9 plus at the moment... Any U firmware without bloat ware??
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
You can't flash directly from one U firmware to another unless you want a hell of a lot of issues that will more than likely cause your device to lose all data connectivity. You can always use ADB commands or a package disabler to remove any bloatware.

Will I lose the ability to enter a sim unlock code after I flash the u1 version 2 firmware on to my xfinity stock s9?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
No. SIM lock is not affected when flashing. If your device is locked to a specific carrier, it will still be when flashed to a different firmware. You will still be able to SIM unlock your device the same way, if you choose to.
[Samsung Galaxy S9  Guides, News, & Discussion] fzambon:
Why does 960u1 have no videocall?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
Because the U1 is the non-carrier firmware, so most carrier related features will be missing from it.

[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
I am not sure. If the Brazil model has a SnapDragon processor in it, then it might be possible. If it is a Exynos model, then probably not.

Flashed to u1 but still can't access the *#2263# menu ..... I want to make sure the bands can be unlocked after i get an unlock code. Please help.
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
Did you factory reset before flashing and did you make sure you used the OYN CSC and not the HOME_CSC? Are you using the stock dialer to access that menu?
[Samsung Galaxy S9  Guides, News, & Discussion] darkmwar:
Did the factory reset in the bixpy+up+power menu before flashing

Did not extract the home_csc at all. These are the files I used:

AP_G960U1UES2ARF4_CL13087505_QB18460723_REV01_user_low_ship_MULTI_CERT_meta.tar

CSC_OMC_OYM_G960U1OYM2ARF4_CL13087505_QB18460723_REV01_user_low_ship_MULTI_CERT.tar

Odin 3b Patched.

Interestingly, when I flashed without a sim card in, it still shows cct(code for xfinity mobile i believe) and knows that the phone is still locked to xfinity sim and ask for an xfinity sim. I understand it is not supposed to sim unlock.

But I though that the *#2263# restrictions is a firmware thing, and using u1 would allow access.
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
I tried the dialer code on my Note 9 U1 firmware and S9 Plus with the U1 firmware. Both bring up the band selection. Both of my devices are unlocked though. The first two of the three under Service Provider SW should change to XAA when there is no SIM in the device, but the last one will not. Are you sure it flashed successfully?
[Samsung Galaxy S9  Guides, News, & Discussion] darkmwar:
Just to give more information about my device, i have wifi and data turned off.

Just restarted my phone without the sim, the service provider sw ver has

SAO_MC_SMG_960U1_OYM_CCT_##_###

############

CCT/CCT/CCT (xfinity)

I am pretty sure I flashed correctly? Odin says success at the end and the device proceeded to restart and the xfinity apps that came with the phone is no longer there.
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
When you went through the setup. Did you enter your Google Account info and login or did you skip all of that? It makes me wonder if the SIM lock is somehow forcing the CSC to load what it has for Xfinity. The U1 firmware should change the first two based on the SIM inserted. When I originally flashed mine, it showed XAA/XAA until I put my T-Mobile SIM in it. Then they changed to TMB/TMB. Does the phones model number show U1?
[Samsung Galaxy S9  Guides, News, & Discussion] darkmwar:
I skipped ALL of the accounts setup (both google and samsung) , i did log in to google play store though when I was on the stock firmware. After flashing, I did not log in to anything.

I am wondering the same thing too, perhaps the firmware knows that it is still sim locked. Yes, the model does show U1. I cannot receive an unlock code from the carrier for another month.
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
As long as it shows the U1 model, you should be fine. When you get it unlocked, pop in a SIM from another privider and see if you get the blue screen with the white Android after a restart. If you do, it should have then converted it to whatever SIM you put in. One of the good things about the U1 is, that it will adapt to any US carrier SIM inserted.

For anyone who would like the newest G960U1UEU3ARH7 firmware, here it is on GDrive.

This is NOT for the S9+.

Galaxy S9
[Samsung Galaxy S9  Guides, News, & Discussion] billa:
The diag code *#2263# is CSC/SIM specific, in other words it's only available if you've first inserted certain carrier's sim (available on ATT/TMO, not available on SPR/CCT/VZW).

So you must first unlock your phone, insert a new or used ATT/TMO sim, let it reboot into the blue screen, remove the sim, and then you can enter the code.

For the carriers for which it's not available it can be invoked by first rooting it, then using ShortcutMaster search for "preload" and try those activities.

Any updates on when S9+ firmware compatible with bootloader V3 will be available?
[Samsung Galaxy S9  Guides, News, & Discussion] renzinator:
It is currently available. Latest version is G965U1UES3ARI1, which can be downloaded using SamFirm
[Samsung Galaxy S9  Guides, News, & Discussion] macycat:
Is there any reason to flash the firmware as opposed to an OTA update via wi-fi?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
That depends. If you are already on the U2 firmware, then you won't need to wipe when flashing it unless you have issues with your current firmware. If you are flashing to the U1 from a U firmware, a full wipe is highly recommended. The U1 is the non-carrier firmware, which is preferred by some depending on the carrier you use. If you happy with your current firmware and aren't in a hurry fir the update. Then wait for or flash the OTA.
[Samsung Galaxy S9  Guides, News, & Discussion] macycat:
Thanks for the response. I should have provided some more information. I have the U1-3ARH7 version of the firmware. It is working well for me. I'm on T-Mobile, and I don't seem to be missing any T-Mobile specific functionality, except for maybe integrated video calling. Firmware version U1-3ARI1 is now available for OTA update, and I just wanted to know if there were specific advantages of flashing vs OTA update.

Thanks again.
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
Video Calling is pretty much all you are missing outside of some bloat. T-Mobile's U firmware does get more frequent updates but the U1 builds tend to be more refined and less buggy. Ultimately, there is no real different whether you flash the OTA or take it over the air.

I unlocked my S9+ that I bought from ATT and flashed U1 firmware on it.

1) Will network performance improve if I flash T-Mobile firmware on it?

2) Will I be able to flash T-Mobile firmware if I'm currently working with SM-G965U1UES3ARI1 TMB/TMB/ATT ?

Most of the time it connects just fine (Kansas and Oklahoma area) but in Abilene, TX, it had trouble connecting to the network. I'd sometimes get one bar of LTE, but data would not transfer or be extremely slow for almost the entire weekend.

[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
You need to flash a U1 firmware with a v3 bootloader or newer. Your AT&T firmware has the v3 bootloader. You can not flash to an earlier bootloader.

Hello I'm on At&t S9 plus, whats the proper U1 firm. to flash if I'm currently on BRJ5 on the U firm.
[Samsung Galaxy S9  Guides, News, & Discussion] omair2005:
With pie beta coming out today, are the steps still the same for unlocked ATT s9+
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
If you are with AT&T for service, you are better off keeping the AT&T U firmware. Flashing to the U1 firmware will not SIM unlock your device, you will lose WiFi Calling, and most other AT&T U firmware features. If you still want to flash to the U1, then make sure the U1 firmware you want to flash has the same or a newer bootloader version than your device currently has. Since you omitted the bootloader version and I am too lazy to look up your firmware. The bootloader version is the number before the B in BRJ5 that you left out.

The steps are the same regardless of what firmware you want to move to unless you are trying to roll back your firmware for the same carrier with the same bootloader version.

I'm Actually on tmobile sim with an unlocked ATT s9+.. So I wanted to go to the unlocked firmware. Or would you recommend flash the tmobile firmware?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
Either way, you will need to flash with wipe to the U1 first. T-Mobile WiFi Calling works fine on the U1 firmware but it does lack Video Calling and T-Mobile apps and bloat. The TMB U will give you the dialer with the Video Calling, Visual Voicemail app (which you can also get from the Play Store), as well as some other T-Mobile bloat. Both firmwares also have band 71 enabled.
[Samsung Galaxy S9  Guides, News, & Discussion] omair2005:

[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
This thread has some links. I don't think any of them are U1 firmware though and they seem to require you be on a specific build before you can flash them safely. Read the instructions to make sure you get your device to where it needs to be to flash one of those.

I'm perfectly fine not running the latest Pie beta. I'll probably stay on this build until Verizon releases the official Pie for the S9. At that point I will roll back to Oreo and then update to Pie OTA.
[Samsung Galaxy S9  Guides, News, & Discussion] m1batt1:
It's not necessarily that I want the latest. But having the OTAs for updated would make it easier to get any bug fixes that might get pushed out. Really it's a matter of preference but for me having OTAs for frequent bug fixes on a beta software sounds best.

Hey guys, I'm kinda new to Samsung again, I had a S2 and later a S5, but things have changed since then a whole lot with the rooting not possible on Qualcomm units.

I want to get rid of the bloat but I don't want to trip Knox if there is actually no rooting right now so I want to ask again (it's been asked before, I know I know, and have read through every post here), will this trip Knox if I flash U1 firmware to my T-Mobile U phone? And secondly, Is there a specific rom/firmware version to flash depending on the latest firmware version on the phone?

I guess that someone would have had to do it to answer, I just don't want to risk the phone just yet, although I got half price by trading in my wife's S7 I still have a long way to go with this phone, hehehe.
