Anyone else getting this when trying to update. Running Verizon 960U1View attachment 4715114
[Samsung Galaxy S9  Guides, News, & Discussion] dglaboi:
Isn't U1 supposed to be carrier-free? My 960U1 is running Pie now without issues and I also flashed it on my ATT 960U
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
It is a non-carrier specific firmware, meant to be compatible with most US carriers.
[Samsung Galaxy S9  Guides, News, & Discussion] funkyverb:
Hi, I have a question about what happens after you flash U1 firmware to a U phone. You know how when you're going through the initial setup screens for a Samsung phone, it has you do setup for some Samsung features, some Google features, and some carrier-specific features? If I install a U1 firmware on my U phone, will all of the carrier-related setup be skipped? And will this also prevent me from getting any carrier bloatware on my phone?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
You can still download and install carrier bloatware from the Play Store. If you used the wipe CSC when flashing, the carrier boot animation will be replaced with the Samsung one. The available LTE bands will also be changed to what the U1 firmware has access to. All future OTA's will be for the firmware you flash.
[Samsung Galaxy S9  Guides, News, & Discussion] funkyverb:
Thanks for the response. A couple questions:

1. What does "wipe CSC" mean? (I know that flashing involves a CSC file, but I'm not clear on what you mean.)

2. After I flash a U1 firmware, is there any difference at all between my phone and a phone that was originally unlocked? Is there any "evidence" left behind to show that it's actually an AT&T phone?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
There are two CSC files in most firmware. You delete the HOME_CSC because using that will bork your conversion and potentially leave you with no service due to a combination of conflicts.

There is one small piece of evidence that does show where the phone was purchased. In the Settings, About Phone, Software Information, there is a Service Provider SW ver. The last if the 3 strings will always be /ATT. The first two will change based on the firmware and SIM installed. Mine says, TMB/TMB/XAC. T-Mobile SIM, T-Mobile U firmware, and purchased in Canada.

What if I cant enable usb debugging

I ended up doing a manual hard reboot and got left with system ui not responding process system not responding or setupwizard not responding. So I can get to the settings menu I'm completely new to the flashing thing but I've researched a decent bit my laptop is to old I've been trying to do updates on it so I could do smartswitch but it says my device is not recognized. I have this j7crown as a backup. But I'm a little lost here people.... is there anyway I can do this from an sd card my recovery screen gives me a option to update using sd card. Or adb And adb is a new thing for me please can somebody give me a super simple dummy walk threw with easy terms or understand
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
What were you flashing from and flashing to? What model is your device? Did you use the HOME_CSC instead of the other CSC?

The only reason I have seen for circumstances like that, is either when an Exynos device is flashed with an North American firmware or a corrupt firmware was flashed to the device.
[Samsung Galaxy S9  Guides, News, & Discussion] redeyewhiteguy:
I've never flashed a thing in my life I had the phone for about 8 days before that happened. The phone is a s9 sm960u1 from straight talk. I was trying to avoid a novel but day 1 I installed kasperkey antivirus I

never owned a phone cost more than $150 and set up all the security features Day 8 my 4yrold decided to take my phone while I was sleeping and tried to unlock it... well the phone goes wacko from there. Trh to unlock it Kaspersky says its stolen need to enter code I used my normal one get to homescreen touch any app I get kicked out I didn't know what was going on. The it would not respond to the buttons then it went on and off whenever it pleased so I looked up hard reset and boom here I am
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
That sounds very odd. You do need to enable Developer Options and USB Debugging to be able to flash. Try performing a factory reset through recovery to see if that gets you to the point where you can enable USB Debugging. If the device is actually stolen, it will be blacklisted by all US and Canadian carriers. There are places online you can check your IMEI and ESN to verify if the device is stolen or not. What you have on your device though, sounds like ransomware.

Flashing the device properly should wipe it, leaving you with nothing installed except what comes pre-installed for the firmware the device has on it. You need to use the modded or patched ODIN to convert it to another firmware. From U to U1 and then to another U or W firmware. You should never go straight from U to U and you should never use the HOME_CSC when flashing. It will preserve data as well as the settings, bloat, and carrier bands from the original firmware, which is usually not wanted.

Did you buy the phone online or from a third party? Carrier specific devices don't come with U firmware. Only devices directly sold from Samsung as SIM unlocked come with the U1 firmware. When flashing, you need to make sure you have the device drivers installed for your device while the device is in Download Mode before opening ODIN. Find yourself the XAA U1 firmware from somewhere (samfrew seems to be the popular choice right now), make sure the firmware has the same or newer version of the bootloader the device currently has, and flash without changing any of the default options in ODIN.

Figured it out, Apparently I wasn't paying attention to the bootloader, When I went to CSC3, its a ver 4 boot.
[Samsung Galaxy S9  Guides, News, & Discussion] :
Yeah I had made this mistake trying to go back to U1 from U.... the recent update CSC7 is awful, the battery life is so bad and for me U1 has better battery and performance in my opinion
[Samsung Galaxy S9  Guides, News, & Discussion] Indyultra:
Ya same here, battery sucks. Hopefully they start rolling out some leaks. CSC3 was glitchy that's the only 2 ver4 I've seen.
[Samsung Galaxy S9  Guides, News, & Discussion] Indyultra:
There's a U1 CSC7 out now, running it now. No glitches SSI far, too early to tell on battery also.
[Samsung Galaxy S9  Guides, News, & Discussion] :
I too am running U1 on my Verizon variant, ended up downloading it from Frija yesterday and so far it's running good

My CSAA version was OTAed to CSC7 2 days ago.

Running smoothly thus far.

Odin flash fail/ SMG960U recovery help

Hello. I attempted to flash my SM-G960U (from Cricket Wireless) with firmware, G960U1OYM4CSC7, from SAMMOBILE. I downloaded the Samsung USB drivers. I used 7-zip to extract the files from SAMMOBILE. There was an MD5 error on the extraction of the AP file. I deleted the ".md5" file extension, making it just a .tar file to allow it to load into Odin. I used the Odin3 v3.13.1_3B_PatcheD. I put my phone into download mode, connected to my PC, and started the flash. The process failed. Now the phone says "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software." I downloaded that, but selecting the recovery function doesn't do anything. There is an option to recover using a recovery code, but I don't know what code to use.

I did manage to note the baseband version of my phone. It's G960USQS3BRJ6. Any help to recover my phone and correctly flash would be greatly appreciated.
[Samsung Galaxy S9  Guides, News, & Discussion] mewcatchew:
You should have 5 files, not 1. Dont use/flash HOME_CSC, use the other CSC. here is the firmware https://samfrew.com/model/SM-G960U1/region/XAA/
[Samsung Galaxy S9  Guides, News, & Discussion] Rally517:
You can still use odin
[Samsung Galaxy S9  Guides, News, & Discussion] Carlo Borbor:
hello, I just wanna ask if my S9 is G960U or G9600? I am confuse because the bootloader and baseband are G960U****** while the PDA and CSC are G9600******* thank you. And is it posible to flash G960U1 firmware on my S9?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
My guess is a SM-G9600 but the bootloader suggests that it might be a G960U/U1.
[Samsung Galaxy S9  Guides, News, & Discussion] bradsh1:
Have Verizon service and accidentally bought AT&T g960u. Flashing to U1 right now for use on verizon. Will this device get OTA updates of any kind with U1 firmware, or must I take it a step further and flash Verizon specific firmware in order to get OTA updates in the future?

I mostly just want it to get security updates without having to manually flash them
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
U1 firmware will get you U1 OTA updates. If you want U OTA updates for Verizon, you need to flash the Verizon U firmware after flashing the U1.
[Samsung Galaxy S9  Guides, News, & Discussion] Carlo Borbor:

I wanna start getting ota's again. I have an unlocked S9. Been on the U for a while. Don't know what U1 to flash to get them again
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
Just make sure your current active CSC matches the firmware CSC you flash and OTAs will work for that CSC
[Samsung Galaxy S9  Guides, News, & Discussion] ReapersDeath:
Hey, so I was wanting to try going to the TMobile firmware. I originally flashed from the ATT to the unlocked XAA firmware, and OTA and wifi calling/mms/sms work perfectly. I'm using Ting, which for GSM phones is basically just TMobile.

The issue is, I can't get RCS to work. TMobile supports the S9+, and Ting just passes all those features through. Ie Ting doesn't have to do anything. If Tmobile has a feature or supports something, then they do. The only issues I've noticed, is in all of the Unlocked S9+ changelogs, not once does it mention "RCS Universal Profile 1.0" added. Though all the carrier versions do have that in the changelog. So I figure thats my issue.

I'm currently on 4CSD4 for Unlocked. Can I flash 4CSD3 for TMobile without issues? Will I still get OTAs? Can I uninstall the bloat with ease? Will it wipe my phone?

Also, where can I find the other file I need? I know I need the main firmware, but for carrier versions don't I need a userdata file?
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
Carrier firmwares are flashed the same way as unlocked, no userdata needed for any firmwares

You can flash any firmware for your model S9 as long as the bootloader version is the same or higher than the current one you have flashed

As above, OTAs only work if firmware and current CSCs match

Cannot uninstall bloat, can disable with package disabler

Yes if you change CSCs it will wipe
[Samsung Galaxy S9  Guides, News, & Discussion] ReapersDeath:
What was all the talk about needing USERDATA in the past?

and my current CSC on Unlocked is XAA/XAA/ATT, but I get OTA updates still. Would this no longer work on Tmobile?
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
Never heard anything about userdata in all my years using Odin, always leave that empty, only AP, CP, BL and CSC get used as they are the only 4 parts of firmware you ever use

If you flash Tmobile firmware and use CSC (Not HOME_CSC) it will switch your CSCs from XAA/XAA to whatever the TMobile ones are and OTA will work, if you use HOME_CSC it will only switch one of them and OTA will not work

CSC = Wipe

HOME_CSC = No wipe

You need to use CSC to switch CSCs for OTA
[Samsung Galaxy S9  Guides, News, & Discussion] ReapersDeath:
From the standard US S9 thread, Userdata is littered all over the place: https://xdaforums.com/galaxy-s9/how-to/g960u-firmware-links-t3763388 . Is it just part of the firmware zip or what? Feel like I've heard it here too.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
No it's not part of the firmware and is not needed

If you think it is needed, probably best to read those threads and ask someone in there what it is, I've been flashing my S9 for over a year now, also my S7 before this and my S5 before that and never once used userdata as it is not part of the firmware

EDIT - a quick google shows it is not necessary but optional

Q:

"if I were to flash the verizon firmware onto my phone (U1) with the userdata file, would i get all of the verizon features, like wifi calling, video calling, etc.?"

A:

"My experience thus far has been: NO.

You may get some like HD Voice and Visual Voice but no Video Calling."
[Samsung Galaxy S9  Guides, News, & Discussion] Venom0642:
Correct, Also i never use Userdata at all.
[Samsung Galaxy S9  Guides, News, & Discussion] whbisondtr:
So I flashed the U1 firmware successfully using the patched odin v3.13.1_3B_PatcheD but in trying to go back to the U firmware, it gets stuck at file analysis. I tried using different odin's but they fail. I've also re-downloaded the U firmware twice and still stuck. I only want to go back because in phone, it gets stuck itself and takes forever to get out of it. I also tried different cords and ports as well.
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
Does the firmware you are trying to flash have the same bootloader version or newer? Do you have USB Debugging enabled?
[Samsung Galaxy S9  Guides, News, & Discussion] whbisondtr:
it's the same, bootloader 4

There is no official U1 AT&T firmware! There are no official U1 carrier specific firmware! If you flash the U1 XAA firmware properly (not using the HOME_CSC), you will receive OTA's for that specific firmware.

I have no idea what would cause that. I used the XAA labeled firmware to flash my AT&T phone to U1 and it works just fine. Only thing I don't get is the "advanced messaging" and wifi calling. But regular texts work.

Yeah. I know it is it was with the initial pie and probably will be with Q.
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
The bootloader has to be the same or newer than the device currently has. The firmware you tried to flash has the v1 bootloader. If it not possible to flash this firmware if your device has a newer bootloader version. Check the firmware version currently on your device, take note of the bootloader version, find the appropriate firmware, and try again.

To identify the bootloader version, look at the last 5 characters. In the firmware you downloaded, 1ARBG the 1 is the bootloader version. There is also no carrier specific U1, so if you see a firmware that claims to be the U1 for a carrier. It is a mixed firmware image that you will want to avoid.

and all other websites out there are so slow that it takes a decade to download the rom from.
[Samsung Galaxy S9  Guides, News, & Discussion] slayer.1942:
Quick solution, login to a VPS, download your file from "samsung-firmware.org" at around 1MB/s to the server, then upload it to the google drive, then download it at the maximum speed.

My major problem with at&t original rom is that, they locked the hotspot feature and you have to pay for your own phone abilities/functionality to the greedy AT&T to unlock it with a certain download cap per month.

So far S9 rocks

I flashed the latest U1 this morning, XAA-G960U1UES6CSG4,

this phone is fast, I have never had a phone this fast before, I switched from S7 to S8(had it for 1 week, due to the antenna issues, returned it), and switched to S9

S9 is awesome

it's just my background is not moving when I unlock the phone, phone makes it blurish, how can we make the background visible,

those Infinity backgrounds are so gorgeous, I want them to keep moving after I unlock the phone

I have a question for this thread. I recently switched to cricket from Verizon visible service for a deal on a Galaxy S9. I'm thinking of unlocking it and going back to Visible next month though. Would visible work just fine on the cricket rom after being unlocked, or do I actually NEED the U1 software in order for a Verizon service to work correctly?

Edit: nevermind. After much more reading it seems like the answer to that is a duh and a yes......can anyone give me a simple guide on what's needed to properly get setup for use with visible coming from cricket? I've already downloaded the patched Odin, and a U1 firmware from that application a few comments back......but I'm a little lost with all this CSC stuff, especially coming from cricket going to visible. It's been a few years since I've messed with anything Samsung or Odin and am new to all this carrier specific stuff as well.......as if visible wasn't finicky enough even on a pixel lol

Also does anybody know where I can get an Odin back up of the latest for cricket incase I ever want to go back? I can find for every carrier but cricket
[Samsung Galaxy S9  Guides, News, & Discussion] Youdoofus:
last question first, Cricket is a MVNO, and i do not recall ever seeing any MVNO specific firmwares out there at all. I flashed the U1 on my Cricket S9 a while ago and havent looked back in the slightest. Cricket is just an AT&T MVNO, dont worry about their firmware.

the CSC stands for "Country Specific Code" and will flash on bits thatll make the sim card recognition process wonky if you want to use it outside of the USA. That being said, its stupid easy to flash CSC files, just time consuming as they take several minuted to load into Odin itself.

All G960U's meant for the US market are the exact same phones and can be switched back and forth across CDMA and GSM carriers with relative ease even when (not if) the carriers tell you that your phone isnt compatible.
[Samsung Galaxy S9  Guides, News, & Discussion] carnivalrejectq:
I ended up flashing U1 with XAA. It's working flawlessly except i lost cricket WiFi calling. I see there's some tricks that are supposed to re enable them but none have worked for me. Ah well, now that I have unlocked my S9 I'm gonna go back to Visible anyway.
[Samsung Galaxy S9  Guides, News, & Discussion] redmessengerbag:
I have a ATT branded unlocked S9 that I use on Tmobile now. By flashing U1 onto my phone, I should be able to enable wifi calling on Tmobile? Are there any updated links to U1 firmware and Odin?
[Samsung Galaxy S9  Guides, News, & Discussion] redmessengerbag:
I've realized that that since I unlocked my phone and switched from ATT to T-Mobile about a year ago, my phone has not received an OTA update, so I still have Oreo and the Baseband looks like it's from last August: G960USQU3ARG7

My questions is, if I want to put in the T-Mobile baseband firmware, should I use the latest firmware, will that brick the phone, or should I go back to an older version of T-Mobile baseband firmware that matches more with the version of the Android OS?
[Samsung Galaxy S9  Guides, News, & Discussion] jcsww:
Flash to the U1. It will give you a great experience on T-Mobile without the bloatware. The only things you will be missing are RCS and Video Calling. Which ever firmware you flash though. Just remember that the bootloader version can't be flashed to an earlier version than what the device has. If the firmware updates the bootloader, you are stuck on that bootloader version as a minimum. Your current firmware has your device on the v3 bootloader, noted by the 3 in 3ARG7.
