help g965u at&t

I need some help everyone. I cannot find a legit link or download or mirror for a stock brk2 att download. I have tried the ones I seen in these forums and the download stops at 30 percent or so no matter the mirror or site I use. can anyone help me out and send me a link to an att brk2 download. I'm on csa7 and it's pretty buggy and laggy. fdr and cache wipe does not fix it.

Planning to switch carrier from TMo to ATT. I'm currently on BRK2. Can anyone please let me know what files should I flash to move to ATT? Or just flashing U1 is good enough.

Thanks in advance.

brk2

att Verizon sprint and Xfinity have rolled out to pie. check your software update. no need to flash when its already out for it.
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
You need to do a few things. First, flash to the U1 firmware with patched Odin. Flash the regular CSC file to trigger a wipe. Let it fully boot.

Then, you need to flash a version of the U with ATT userdata. BRJ5 looks like the most current I've seen with the userdata. I'll provide you a link to the USERDATA in case you can't find it. Make sure to flash userdata, and the regular CSC again to trigger a wipe.

Boot your phone *WITH THE ATT SIM INSTALLED*. If you don't do this, you'll have to start over.

Let it fully boot. Sign in, etc. At this point you can either let the OTAs install one by one, or Odin to CSAB.

Alternatively, you can stay on U1. You will loose VoLTE, wifi calling, video calling, and advanced messaging. You will also be unlikely to get most of that working anyways unless you bought the device from ATT. The WiFi calling won't provision unless the device is in their system. Not sure about the rest.

I am currently on Beta 4/ZRLG, can I use this firmware to get back to official AT&T on Pie?
[Samsung Galaxy S9+ Guides, News, & Discussion] KedarWolf:
When I try to run Software Update on G965USQU3CSAB I get "Your current software version isn't supported." error message.
[Samsung Galaxy S9+ Guides, News, & Discussion] rmarinella:
I am on TMO, same message. Its official, probably means your carrier hasn't made the OTA available yet. After using CSAB for several hours, I see no improvement over the U1 Beta ZRLG, so I have opted to go back to the U1 Beta firmware.

Anyway, as far as the message is concerned, its the most current version, no no need to check for an update just yet.
[Samsung Galaxy S9+ Guides, News, & Discussion] KedarWolf:
I installed ARL1 instead of CSAB and it's fixed. :D

Edit: Just found out ARL1 is 8.0, not Pie. :eek:

Second edit: I'm going to flash the CASB again but include the CSAB User Data file in the flash, see if it fixes the System Update issue. :p

clarification on S9+ unlocked

So I have read this entire forum but have a question. My Samsung is unlocked and currently on Verizon. According to Verizon, they do not expect my OTA to be released until March. Can I use the firmware in this thread to upgrade? My phone info is SM-G965U1 running baseband G965U1UEU3ARL1 service provider software says VZW/VZW/XAA

Any insight would be appreciated.
[Samsung Galaxy S9+ Guides, News, & Discussion] skeppley:
You can, but see the OP:

"Drawbacks of flashing G965USQU3CSAB on the unlocked version (SM-G965U1):

CallerID no longer works unless you subscribe to carriers CallerID service.

Installs carrier bloat.

Benefits of flashing G965USQU3CSAB on the unlocked version (SM-G965U1):

Will enable all carrier specific features (video calling, etc, etc)."

If you dont mind the carrier installed apps and features you should be fine.

Thanks for the quick reply. That's what I thought, but wasn't sure since T-Mobile hasn't released their pie update.
[Samsung Galaxy S9+ Guides, News, & Discussion] BLznFuN:
I have a quick question, but first let me explain...

I have the SM-G965U on Sprint and I recently installed the Pie update. I don't like it and wish to drop back to the Oreo version. I stopped by my local Best Buy and spoke with the Samsung representative there. He told me I can flash back to Oreo using Odin. He pointed me to SamMobile file located at https://www.sammobile.com/firmwares/galaxy-s9-plus/SM-G965U/USC/download/G965USQS3BRK2/249814/ . He said this was the last Oreo for my phone. He said I could also send it away to Samsung to have them unlock it to gain access to the stock built-in caller-ID. I hate having to pay Sprint for this.

When I came home tonight, I was googling unlocking my phone and I stumbled upon this thread saying I could use the unlocked version on my phone and not have to send it to Samsung. I just have to do it using the patched version of Odin.

So my question(s) is this...

I found the unlocked version G965U1UEU3ARL1 with a link on this site and I also found it on SamMobile at https://www.sammobile.com/firmwares/galaxy-s9-plus/SM-G965U1/SPR/download/G965U1UEU3ARL1/251291/ . I wish to keep carrier specific stuff, especially the "Chat" in text messaging (unless chat is a Samsung thing) and the Voice over LTE (enables calls and surfing at the same time). I saw that the CSC file in the version provided from the link on this site (from a reply) is supposed to automatically determine which carrier you need. Does this also ensure the carrier specific stuff works? If not, should I use the one from SamMobile for Sprint? If I do, will I still get access to the stock Caller-ID? If not, and I use the one listed in the link from this site, which one? There are two. One is a .7z and the other is a .rar. File sizes and upload dates differ.

Thanks for any help and answers you are able to provide.

PS. The G965U1UEU3ARL1 version is Oreo correct?
[Samsung Galaxy S9+ Guides, News, & Discussion] hyperblu:
You will lose all carrier specific features switching to unlocked, but should still retain VoLTE. The idea of switching to unlocked firmware is to lose the carrier bloatware. You will also get free caller ID with the unlocked FW. To answer the question of the different file sizes is that both are compressed differently using different programs. Use 7zip for the .7z file and the WinRAR file. It will open and extract both.

---------- Post added at 02:13 AM ---------- Previous post was at 02:10 AM ----------

The CSC for the unlocked firmware will be XAA. That is "unknown" and will automatically change to your carriers CSC when the Sim is inserted.

---------- Post added at 02:17 AM ---------- Previous post was at 02:13 AM ----------

For instance, if your carrier offers video calling, WiFi calling, etc, you will lose those features. VoLTE is standard, caller ID is standard (carrier redacts this and charges for it when NOT using unlocked firmware) , etc. IMO, unlocked is by far better as most carrier specific apps that you DO want can be installed through play store anyway.

Also, yes. ARL1 is the latest firmware with Oreo for the US unlocked s9+. The Pie official update will be released in a few days.

[Samsung Galaxy S9+ Guides, News, & Discussion] BladeDiablo1140:
Ok so I'm totally new to all of this. I followed all of the steps to flash SM-G965U, Odin shows completed, phone rebooted and came up fine but Android OS still showing as 8.0. Am I supposed to do anything else now?
[Samsung Galaxy S9+ Guides, News, & Discussion] BLznFuN:
Ah ok.

Ok, that's good to know. I don't need much. I hardly ever use wi-fi calling, and I don't think sprint has video calling. So how does that work for the ARL1 that is on SamMobile that is labeled for sprint or is branded sprint?

I should be ok. I've done this before, but never on a device that has been still under warranty. Just wanted to have all information possible before I continue. I presume, if ever, I can go back to the stock latest Oreo that I have downloaded at any point using Odin?
[Samsung Galaxy S9+ Guides, News, & Discussion] hyperblu:
Once the bootloader number changes as the updates go on, you will not be able to revert back to Oreo. You can only refuse to install updates as they come.
[Samsung Galaxy S9+ Guides, News, & Discussion] BLznFuN:
Ah ok.

Ok, that's good to know. I don't need much. I hardly ever use wi-fi calling but would there be any way to retain or re-install it; and I don't think sprint has video calling. So how does that work for the ARL1 that is on SamMobile that is branded sprint or on an unlocked phone directly from sprint (if that's even possible)? Do they have that stuff removed? I've heard of people getting unlocked phones from their carrier, unless they're pre-buying the phone and then taking it to a carrier?

I should be ok. I've done this before, but never on a device that has been still under warranty :D:D. Just wanted to have all information possible before I continue. I presume, if ever, I can go back to the latest stock Oreo that I have already downloaded from SamMobile at any point using Odin?
[Samsung Galaxy S9+ Guides, News, & Discussion] hyperblu:
But as of right now, I would say through the next few updates, you will be able to flash back to that same firmware package you have for the foreseeable future at any point, yes.
[Samsung Galaxy S9+ Guides, News, & Discussion] BLznFuN:
Ok I don't know why that posted twice, but I did add some stuff to the second one. I plan on staying on Oreo. One of the main reasons I am switching back is for call recording. Pie removed the ability to do this. Something about removing the API and workarounds completely.
[Samsung Galaxy S9+ Guides, News, & Discussion] hyperblu:
There is no such thing as a branded Sprint g965u1 firmware package. What you are seeing is what firmware/date the u1 firmware was pushed by that carrier as all firmware updates are passed through carriers.
[Samsung Galaxy S9+ Guides, News, & Discussion] BLznFuN:
You did mention to just refuse updates as they come... I have mine currently set to manual updates. If I don't check for updates from here forward (after the flashback) it shouldn't check and notify me correct? If not, is there any way to stop the annoying notification to update every few days?

---------- Post added at 01:43 AM ---------- Previous post was at 01:42 AM ----------

This thread is for the Oreo I do believe. I was pushed the Pie update a few days ago but I hate it and I'm reverting back to Oreo. If Pie's what you're looking for you should have it soon.
[Samsung Galaxy S9+ Guides, News, & Discussion] hyperblu:
Kind of hard to explain. The u1 and the u is the same exact firmware across the board. Regardless of carrier. The sim identifies with the carrier and the carrier packages are added on the initial setup of the phone. The unlocked will never load carrier bloat, the "U" branded devices come blank and are preloaded to the carrier the sim is tied to, if that makes sense. Also, WiFi calling will not be able to be brought back. However there are lots of app alternatives to replace that, just not using your phone number... Google voice will essentially do the same thing.

---------- Post added at 03:45 AM ---------- Previous post was at 03:44 AM ----------

What firmware package did you flash?
[Samsung Galaxy S9+ Guides, News, & Discussion] BLznFuN:
Ah ok. So in theory then I could use the SamMobile of the ARL1 which is the same as what's linked in this post?
[Samsung Galaxy S9+ Guides, News, & Discussion] hyperblu:
You can set to check for updates manually and not have to worry about being pestered. I'm just saying once you cross into an update with a different bootloader, there's no going back to Oreo.

---------- Post added at 04:22 AM ---------- Previous post was at 04:09 AM ----------

Oh, BTW I don't know if the Samsung rep told you or not, when you go to load CSC into Odin, you'll have 2 CSC files... CSC_HOME will retain your data, but because you're switching between carrier and unlocked, it's in your best interest to use the other CSC file (backup your data) to perform a clean wipe, otherwise you may lose VoLTE capability. A full wipe "should" auto detect your APN settings from the sim card and just "work". If for some reason you don't have VoLTE after initial setup, Google the APN settings you can find for your carrier and you can more than likely get it working just by changing the AP name. I have two identical Verizon s9+ and one worked great, the other one had to change the AP name to get it working.

I got the new firmware on my phone, or at least I think I did. Unplugged the cable on the first reboot, it booted again to recover, then rebooted again and stuck awhile on the Samsung logo.

[Samsung Galaxy S9+ Guides, News, & Discussion] BLznFuN:
Ok I used the other file. Boots now. Another question, I found in another thread that you can use the "Userdata" file from the carrier locked firmware to use in Odin to unlock the carrier specific features on an unlocked phone. Someone here on XDA (and I can find the post) said they did it successfully using the patched odin. I ask this, because I can not get VoLTE to work, even using the CSC or the APN method. I could care less about Wi-Fi Calling, but RCS should be enabled with VoLTE as well from what I gather.

If I can get RCS working the default messaging app and VoLTE, I'll be giddy af. I suppose HD calling is a carrier branded thing too. I just remembered that one and really liked it. Would be awesome if I got that back too somehow. Maybe using that Userdata file if its recommended.

---------- Post added at 07:26 PM ---------- Previous post was at 07:24 PM ----------

And if I can use the Userdata file, do I have to reflash everything or can I just use odin to flash that single file? Doesn't really matter either way, my phone is currently fresh and it only takes about 7 minutes to reflash the whole process.

---------- Post added at 07:40 PM ---------- Previous post was at 07:26 PM ----------

LOL I found Wi-Fi calling under the phone app settings. So wi-fi calling looks like it is still there, just in a different spot, and confirmed it works.
[Samsung Galaxy S9+ Guides, News, & Discussion] hyperblu:
You'd probably want to flash everything along with the userdata file. If you can find one, try it and see what all options it might enable and start from there. The userdata file is separate from the firmware package and shouldn't matter what firmware package or phone it was for. After we find out what all it gives you, we can work on the messaging app and so-forth.

I went back to Oreo for two reasons, call recording (main one) and the unlocked spam caller protection. I'll still have the first one, but loose the second one with carrier branded. At this point, might be the best option unfortunately. I do use VoLTE. :( Having the unlocked was just for the spam caller protection.
