Ok. Does it make any difference if the last CSC remains unchanged. From what I know, the phone will still get OTA updates from the current carrier the phone is on etc...example if I have VTR/VTR/VZW. Where VTR is my current service provider. I'll get updates from the VTR update schedule.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
The last has nothing to do with OTA's. As long as you install the full firmware correctly, OTA's will install normally.
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Sorry but no. All I do is provide the firmware. So you'll have to search the threads for tips

Just because it didn't change when you flashed the firmware, doesn't mean that it can't be done. I've seen it done before
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Build SB5 is up on SamFirm if anyone wants to try it. Only available with CCT CSC for now, but anyone can flash it sans USERDATA
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
Also on UPDATO. Slow As Hell Though.....180kbs on my 60MBPS connection

https://updato.com/firmware-archive-select-model?record=D431CDBA446511E99F15FA163EE8F90B

Sammobile too....a little faster than Updato
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
I don't know why anyone uses either of those, unless you're paying for Sammobile Premium. SamFirm is blazing fast all the time.
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
yeah i just learnt how to use SamFirm lmao doing 4MBs now hahahaha. Thanks
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Looks like it's going to bootloader 4 now. Build SC3 is up on SamFirm now for T-Mobile. Other carriers probably soon to follow
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
there a new firmware?
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Yes, that's what that means
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
got it bro

[Samsung Galaxy S9+ Guides, News, & Discussion] Venom0642:
Don't forget if flash you will not be able to go back since you can't go backwards on bootloaders, just making sure you and others know.

occasional Settings has closed message. annoying and i cannot go back cos its a new bootloader. i wud deal till a new build is released tho
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
That's d nagging problem
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
can probably fix it with a factory reset

Wiped it...let's see

---------- Post added at 05:34 AM ---------- Previous post was at 04:39 AM ----------

Think u are right. It's kinda weird cos I always wipe in recovery before I upgrade
[Samsung Galaxy S9+ Guides, News, & Discussion] Cyclone Emperor:
What fw do I need to be on to update?
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Doesn't matter. You can always Odin flash from any previous version. But remember that you can't go back, if the bootloader has been incremented
[Samsung Galaxy S9+ Guides, News, & Discussion] Cyclone Emperor:
I'm aware of the bl, I just figured it was like the betas where you had to be on a specific fw to update
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
No. Betas are only for new Android versions.

You won't get the OTA update notification until your carrier rolls it out. But anything that hits SamFirm is official, and can be installed by anyone.
[Samsung Galaxy S9+ Guides, News, & Discussion] alirz:
is the Combination file the same for U and U1 devices? given both devices are on the same bootloader version.
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
Yeah, use patched ODIN to install any CSC on any U or U1 device. Pay attention to the bootloader version though. You cannot move down bootloaders

---------- Post added at 03:00 PM ---------- Previous post was at 02:57 PM ----------

It's fine honestly. I think there is a bug with either night mode or with gesture navigation. I get a settings closed unexpectedly error when either of those two are on and I swipe down to check my notifications. I redownload the firmware and installed it clean again and I have not replicated that issue though I'm not using night mode nor gesture navigation now
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Combination files in this case, use the base U1 firmware but with a different CSC and userdata instead of what it should have. I1 base with a U CSC and userdata and calling it TMB U1 or ATT U1. The problem with this is that you will not be able to accept OTA's on a device running these combination firmware. If you want your device to be complete stock after conversion that can receive OTA's. Then you you need to use official complete stock firmware.
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
Exactly...I gave him the short answer tho lol
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
No offense, but it doesn't sound like either of you have any idea what a combination file actually is. It's not retail/user firmware. It's special firmware used by Samsung for diagnostic, service, and repair issues

Hi everyone!

I have S9+ at&t U.it's possible to flash to U1 and what should i use to not have problems later!

Thanks everyone!
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
Yeah. Use patched ODIN tho. Note though that you may lose OTA update capabilities
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
Is your device already unlocked? As in you got the unlock code from AT&T?
[Samsung Galaxy S9+ Guides, News, & Discussion] brokemember:
Slightly confused here

I first flashed RB7 with the TMB Userdata.

After which I RBG with TMB Userdata again.

However my boot animation is still showing ATT

Am I messing up somewhere. Or is this the correct process

1) Flash RB7 with ATT Userdata

2) Flash RBG with TMobile Userdata

OR

1) Flash RB7 with ATT Userdata

2) Flash RB7 with TMobile Userdata

3) Flash RBG with TMobile Userdata

Thanks in advance.
[Samsung Galaxy S9+ Guides, News, & Discussion] monsterlag:
When you flashed from ATT to U1(Unlocked) did it remove the ATT boot logo and ATT bloatware?
[Samsung Galaxy S9+ Guides, News, & Discussion] brokemember:
So to clarify. What I am doing now is:

1) Flash U1 (Unlocked) - Boots without Att and popup comes that the phone will start with carrier settings if you hit OK

2) Flash RBG with Tmobile Userdata — Boot animation shows ATT Logo for some reason

Can't Figure out what I am doing wrong.

---------- Post added at 09:27 PM ---------- Previous post was at 08:58 PM ----------

So now I did this

1) Flash U1 (Unlocked) - Boots without Att and popup comes that the phone will start with carrier settings if you hit OK

2) Flash RB7 with Tmobile Userdata — Boot animation shows Tmobile Logo

3) Flash RBG with Tmobile Userdata — Boot animation shows Tmobile Logo, however am getting TMB/TMB/ATT

Any clue how to fix that and get TMB/TMB/TMB
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
You can't change the last code, where you see ATT that cannot be changed.

ATT is the original product code, TMB means you running T-Mobile software along with a T-Mobile SIM so that's why you see TMB/TMB
[Samsung Galaxy S9+ Guides, News, & Discussion] brokemember:
Does this have any effect on the phone features itself —*as in Tmobile centric features (Wifi calling, Visual Voicemail, Hotspot, etc)?
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
No the 3rd code is just the original device carrier code.

T-Mobile features are based on the software and the SIM provision, so you have nothing to worry about. Ignore the last code
[Samsung Galaxy S9+ Guides, News, & Discussion] brokemember:
Thanks. I checked Voicemail and Hotspot and those are working fine. Wasn't able to test WIFI calling.

Lol I guess it's my OCD driving me insane. To be honest I probably wouldn't even have checked this in settings if it wasn't mention earlier in the thread.

Just want to make sure I have everything working fine since the phone is for the Mrs. and she is about to travel for work and wouldn't be able to fix anything if it goes wrong.
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
No problem,

All features like WiFi calling, Hotspot etc would work once your SIM is properly provision by the carrier and you are running their version of software. So you have nothing to worry about
[Samsung Galaxy S9+ Guides, News, & Discussion] brokemember:
Thanks. Appreciate you clarifying that for me.

You have a wonderful day!

---------- Post added at 07:49 AM ---------- Previous post was at 07:40 AM ----------

I did just notice one thing different between using att userdata versus tmobile.

When the phone was still on ATT sliding down anywhere on the home screen would open the notification panel and sliding up would open apps.

In Tmobile both (Up and down) gestures just open the apps.

Only way to get gestures to open the notification panel is by using the finger print gesture.

GPS Issues after flashing Carrier firmware?

Hi. Are you still having issues with GPS after flashing your S9+ unlocked 5UI to ATT firmware? I could care less about some of the carrier features, but not getting LTE data during phone calls is extremely irritating. That being said, if flashing breaks the GPS, that's a deal breaker for me. Maybe it just takes some time for the GPS to reset itself?

Please advise.

Thanks.
[Samsung Galaxy S9+ Guides, News, & Discussion] aka120:
Yes, my SM-G965U1 is having a GPS signal loss/interruption issue on the AT&T firmware. However, this issue was present out of the box from day 1, on the stock G965U1 firmware. Flashing the SM-G965U1 with a G965U carrier branded firmware had zero effect in my case. :confused:
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
After flashing the U1 firmware why am I seeing service provider info?

Example am seeing XAA/XAA/ATT..

In previous model when you flash the U1 there wasn't any service provider info.

Anyone experiencing this or maybe I did something wrong?
[Samsung Galaxy S9+ Guides, News, & Discussion] sinman02:
I flashed the AT&T firmware RB7 on my unlocked Galaxy using aka120's steps. I flashed the home csc file first then the other csc file (with the other RB7 files). None of the carrier features are working. Wifi voice and VVM setup give me errors. The biggest kick in the nuts is that the LTE data still doesn't work during phone calls (switches to 4G only), which was the main reason I flashed to AT&T firmware. Nuts! Using same sim card I had in my S7 and S8. It sees an update to RBI....I'll try that for ****s and giggles...otherwise, may as well flash back to RG7 5GU1 to get rid of all the bloat...Damn!
[Samsung Galaxy S9+ Guides, News, & Discussion] monsterlag:
The last part is the original device provider code and can't be changed as of now. It doesn't affect any fuctionality whatsoever, just OCD :P. I have the same.
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
Well that sucks because on the Note 8 and previous model when I flash the U1 version I don't have that "service provider info field"
[Samsung Galaxy S9+ Guides, News, & Discussion] sinman02:
Well RBI didn't improve matters at all.....so back to the stock unlocked firmware....bummer...
[Samsung Galaxy S9+ Guides, News, & Discussion] nugzo:
My GPS issues are gone after installing some GPS apps. GPS status by MobiWIA and GPS Test v3.0.3. Pro versions. I installed the U RB7 via Odin to my U1 and then it OTA's to RBG. All of those i did around the same time so not sure which was the fix, but GPS has been spot on. I had had issues with smart lock not keeping my phone unlocked at designated places. when adding a location it was a mile away on the other side of the neighborhood. Now its in my back yard. Was also getting GPS error messages and had to step outside to lock. That has never happened before. Wasn't any special weather conditions, just a regular evening.

I'm starting to wonder about this... Nooone has been able to duplicate it and he's done nothing special. i dunno :confused: He just has a special phone. Wish I was that lucky :rolleyes:
[Samsung Galaxy S9+ Guides, News, & Discussion] mc_365:
The last subset is the phones origin, I think that can only be changed if you have a rooted device and then you can edit some files through adb or something of the like.

What I find interesting is you've got yours to XXA where my phone is factory unlocked and I flashed a bunch of stuff but went back to the original firmware and I got VZW/VZW/XAA even after many flashes and resets. I don't have any other sims to test it with but interesting that your are getting it to just be XAA?
[Samsung Galaxy S9+ Guides, News, & Discussion] kevindevonwilliams:
I know the last code is the phone origins, I know this is normally displayed on the U firmware but this is actually the first time am seeing this info on the U1 firmware also.

The phone is originally ATT but because of the SIM I used during set up I got it set up as XAA because I hate ATT bloatware
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
OTA's will work fine as long as they don't use the HOME_CSC and flash the full stock XAA U1 image. Not the mixed firmware carrier U1 firmware that seem to be appearing everywhere. There are no official carrier specific U1 firmware.
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
The CSC that you flash has no bearing on OTA updates. HOME CSC is the exact same file as the other one, except the other one does a data wipe and HOME doesn't.

Also, there's no such thing as "mixed firmware" for U1. Every single U1 package is the exact same file(s)
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
It can when you are trying to convert from one firmware to another, because it preserves data that needs to be preplaced. When you combine a U1 base firmware with the CSC and userdata from a carrier, like Sprint, you create a firmware that will work but will not receive OTA's due to firmware components not matching up with the OTA check.
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
You're going to have issues, glitches, and crashes galore if you convert firmware without wiping - and that's if the other firmware even flashes successfully, which it might not do without the pit file that is only found in the regular CSC. So it's automatically assumed that you wipe when you convert

Is there a V.4 update for U1 yet? U1 firmware runs way better and battery life is noticably better in my opinion...
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
Nope
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Historically, the carrier models always get updated first. It makes sense for Samsung, because those models outsell the unlocked ones 50 to 1
[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
No one buys unlocked devices in this country....everyone rather takes a contract or some
[Samsung Galaxy S9+ Guides, News, & Discussion] :
I was only asking because the battery life and performance is better on the U1 firmware with my experience anyway :)
[Samsung Galaxy S9+ Guides, News, & Discussion] VandyCWG:
Question from this guy...I flashed the U1 firmware onto my Sprint S9+. It's showing current version G965U1UES3CSAA/G965U1OYM3CSAA/G965U1UES3CSAA with a Security Patch level of February 1, 2019.

Is that correct a patch level and should this get OTA's? Or will I just hawk the forums until the newest security patch is pushed?
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Yes that is the latest version and yes you should get OTAs. But firmware files are routinely available for download before you get the OTA notification so feel free to hawk if you want it ASAP
[Samsung Galaxy S9+ Guides, News, & Discussion] VandyCWG:
Thanks for the quick reply. The older security patch date had me wondering.

It's weird there haven't been any U firmwares released yet aside from the T-Mobile, as far as bootloader version 4 goes I am on the Verizon variant
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Yes it's strange that no one else has gotten bootloader 4 yet. Likely this week, or next
[Samsung Galaxy S9+ Guides, News, & Discussion] :
my battery life on the original version 4 update was not that great so I flashed the unbranded version 4 that another user had posted here and since I flashed it my battery life has been even worse it's ridiculous and there are a lot of bugs so I am keeping my fingers crossed that it comes out soon, it would be even better if a U1 version 4 came out first for me anyway lol
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
I'm not sure what the difference is between "unbranded" and U1. Any U firmware is carrier branded, so if you flash U firmware, you should retain whatever carrier branding you had before the flash
[Samsung Galaxy S9+ Guides, News, & Discussion] :
I'm not sure either, I just know that when I've used U1 oppoesed to U my phone ran much smoother and had better battery life
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Right but you said "i flashed the unbranded version 4....". But you can't have flashed U1, because a bootloader 4 update hasn't come out for U1 yet
[Samsung Galaxy S9+ Guides, News, & Discussion] :
I meant what I assume is either the T-Mobile or unbranded v4 that was posted here the U version

[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
Oooh nice find! It's also on SamFirm, so I'd recommend using that for anyone who wants it, since very very few people pay for Sammobile Premium. Remember that this is a new bootloader so you can't go back, once flashed!

[Samsung Galaxy S9+ Guides, News, & Discussion] kenennaoyeka:
What he means is that if u move to CSC7 u cannot go back to any other former firmware except CSC3 cos the bootloader was updated to version 4
[Samsung Galaxy S9+ Guides, News, & Discussion] yoyo711:

As long as the bootloader version is the same or newer, you can successfully flash it. In the case of those two firmware, they are both v4 bootloader firmware. in 4SC7, the 4 is the bootloader version.

Ues. The U1 firmware is more compatible with T-Mobile than it is with any other carrier.
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
That's not true. It supports all networks equally
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
WiFi Calling does not work on most carriers with the U1 firmware. It does with T-Mobile. The only difference other than some bloat between the TMB U firmware and the U1 non-carrier specific firmware is, there is no video calling natively built in for T-Mobile.

What's the website that you get your firmware from?
[Samsung Galaxy S9+ Guides, News, & Discussion] namtabeht-6:
Update from beta

Can't seem to get Odin to flash anything onto my phone. Currently on the Pie Beta 2 (G965USQU3CRI7) on AT&T S9+. Have tried Odin with many different firmwares, different cables/different USB ports. have USB debug on, updated drivers, using patched odin.

Anybody know of a way to update via SD card similar to how i updated to Beta 2 via SD card file? Can't seem to find firmware "from" G965USQU3CRI7 using firmware.science (it's not an option for current firmware on the dropdown).

Thanks!
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
You have to have a valid previous/current version, in order to update via SD. In your case, it will fail since your current version is a beta.

If Odin isn't working, we need to know exactly why, or what the specific error is
[Samsung Galaxy S9+ Guides, News, & Discussion] namtabeht-6:
I was finally able to flash using Odin, and used this post as a guide: https://xdaforums.com/galaxy-s9-plus/help/stuck-zrj8-g965u-t3873120 which helped me get updated to ZRK9 firmware using the OTA/SD update method.

Am I free to use a G965U1 firmware from firmware.science as an udpate now? i have an AT&T phone, but live in Canada and don't need any of their features/bloat. I'm not on their network, and my sim works fine down here as is but would just love to get rid of the extra useless apps.

thanks!!
[Samsung Galaxy S9+ Guides, News, & Discussion] iBowToAndroid:
No. Anything with Z in it is still a beta build. You need to Odin flash - NOT do it via OTA/SD
[Samsung Galaxy S9+ Guides, News, & Discussion] namtabeht-6:
i knew it wouldn't be easy! (and probably explains the bugs/issues i keep having re: edge panel/reminders etc)

so for the sake of saving me another days worth of searching, can i flash this firmware onto my phone via Odin (or is the bootloader change going to mess things up?)

(tried to post the link but i'm too green so i've truncated...

sammobile.com/firmwares/galaxy-s9-plus/SM-G965U1/USC/download/G965U1UES4CSD4/268613/

if i cannot use that, i'd be forever grateful if you could point me in the direction of a flashable, U1 firmware for me. again, don't need any carrier bloat or features, just want a clean install of Pie that will hopefully have less bugs :)

THank you so much!!
