[HOW TO] Carrier Switch Galaxy S8/S8+ **SNAPDRAGON**

*READ FIRST*
This thread is now completely dedicated to the aspect of Carrier Switching on the Snapdragon model of the Galaxy S8/S8+, the current root progress can be seen here:
Current ROOT Progress for G950U/G955U Snapdragon
Please Note that if your device is network locked this WILL NOT unlock it for use on other carriers, however it will allow the switching of carriers and carrier specific features on network unlocked devices just by changing sim cards, the device will reboot and your done. As for those with a network locked device this thread still applies to you, if you are interested in a bloat free experience(that is faster and smoother than stock touchwiz), on your Galaxy S8/S8+​
Let's Begin!
Download the firmware for the unlocked S8/S8+ here:
G950U1UE1AQDC_XAA
Download the Prince Cosmy version of Odin here:
Odin_3.12.3_Modified
Enable developer options on your device:
Settings----->About Phone----->Click Build Number 7 times
Enable USB Debugging:
Settings----->Developer Options-----USB Debugging
Put your device into download mode: Volume Down + Bixby + Power
(accept the warning and connect your device to your computer)
Take the G950U1.zip you downloaded in step 1 and extract it, then place the BL,AP,CP,and CSC files into their corresponding places within Odin and press start
Once finished the device will boot back up and you will be free to disconnect it from your computer
You now have the unlocked, bloat free, firmware on your S8/S8+

I've been getting protocol version errors trying to flash via odin 3.10 (the only one that I can download)
EDIT: installing now, needed the latest odin

Oh, ok. Didn't realize that. So does this overwrite the carrier info? Or is that untouched?

As of right now there is no way to overwrite carrier info, we are working on it though. That reserved comment is going to be where i put all that is known, been tried, etc with carrier switching just a little busy right now

My build number is SM-G950A and my firmware is G950USQU1AQD9. I am quite familiar with the concept and process of rooting but I have never had an opportunity to actually get into it. I was wondering if my device is compatible with this firmware. If so I am fine with testing so long as there is a reliable way to restore my phone if something were to happen.

I went ahead and did the favors of doing some testing, in terms of restoral anyhow. From my experience, you do not have access to the usual desktop, and you have very few apps by default(none actually, just settings). I was able to revert to the original stock firmware via odin without a hitch. I did not try installing TWRP on this firmware however, but I can confirm the existence of OEM Unlock, which, by itself, claims to unlock the bootloader.

This is compatible with your device all US versions of the S8 and S8+ have the same model number. I have your stock firmware i just need to upload it to androidfilehost

If anyone feels like it joining I have created an IRC room we can all chat in and brainstorm things. It's #sgs8 on irc.freenode.net. Hasn't had many users since I created it but I lurk in there when I'm at home. I'd love some company. Let's get this thing rooted so we can shut all the haters up!

Glad to see more devs working on this

Tripped knox is forever. There is a fuse that blows on the phone. That said, there are workarounds on rooted phones (you might as well stay rooted). Try looking for edits for the build.prop to restore functionality to Samsung Health and other affected apps. Dr Ketan still makes ROMs I believe and should have something for you.

Then I won't root. The only reason I want to root is because I need to use mod apps like Spotify but sadly all the ones v been downloading never worked. Can you help me out please. Thank you

I don't want to be rude, but your question was answered already. You can't untrip the know counter. It's an actual fuse, that physically becomes blown. This isn't a software setting, but an actual, physical fuse.
It goes back to the days of people using exploits, and in rare cases would damage their phone in the process, but the phone worked enough to relock the bootloader. Then the person would send their phone back and blame it on the manufacturer. So now Samsung decided to put in an actual fuse so that if you decide to unlock it, your warrenty is permanently void.
Bottom line, your out of luck. I know any unlock would have given a warning that it is PERMANENT and that it would VOID YOUR WARRENTY. Wether you read it and ignored the warning, or didn't bother to read it, it's on you for unlocking your bootloader.

Yea I remember those days... Well truth is I haven't rooted.. I was considering it until I read the warranty part... My point is, the reason I want it rooted is because I want to use some modded applications. I researched further and found out I could use some without even rooting. So i tried downloading Spotify mod app, but unfortunately it didn't work. I couldn't get recent application for it, what I kept getting was an outdated mod app. In all it didn't work. So am asking if there's a way to use mod apps without rooting the phone. Thank you

You'll have to wait until someone mods the latest app. Or, you could just pay for Spotify. For the record, I used to use a modded Spotify, and they typically patch within a day or two of a modded apk being released. They may have finally switched to server side authentication which is why your likely not seeing an updated version. I stopped bothering because it's just a cat and mouse game. I didn't feel like Spotify was worth it, so I moved on.
I find Google Play Music is a better deal. I get add-free YouTube, and all the same music as Spotify, for the same price.
On a side note, I don't believe Xda allows modded apks that bypass paid features. There are sites that cater to such things, but I'm pretty sure it's a no-no here. They tend to support devs / companies as opposed to cheating them out of money.

Hi dude, I have 2 questions, I just buy S9+ 965U sprint unlock running U3ARH7 can I flash this 965U1's fw? and What is CSC in U1 fw? thanks

Hi, you can flash the U1 firmware on the Sprint 965U. You need to use the patched Odin linked in the OP. The CSC file included is for multiple carriers. When flashing it will read your sim and setup accordingly.

Umm what's new? The "I" September patch Odin's have been out since mid September.

The thread provides detailed instructions and the most current firmware. The instructions are new to the thread and so are the links. Didn't realize I was required to explain what was new to you.

Uploading G965USQS3ARIB firmware now.

Hi, Q. If I install the ARIB version in my U1 under att, I still can use another carrier sim right?
I'm traveling to Argentina soon and I want to know that.
Thanks

Should be fine , your U1 is unlocked. The sim card in Argentina might not set up the APN for you regardless of what firmware you're on. Personally, I would use the U1 firmware though.

I don't use the "B" revision firmwares, but there was at least one listed as a BOYD firmware. Since your already on U1 and loosing wifi-calling, HD voice, volte, etc, that might give you the best luck. Might be something to look into.

You asked about sim swapping for traveling. The BYOD firmware makes for easier sim swapping. It's designed to populate the carrier settings when you insert a sim instead of needing to wipe your device.
As for ATT features, I believe those firmware are for the U firmware, so yes, you'd regain those features, but you'd get the ATT bloat. I don't mind the bloat personally. I just remove the junk I don't need.

AT&T Note 8 will not update

AT&T Note 8 - purchased directly from AT&T
Stock - no changes/modifications
Baseband Version: N950USQU4CRD7
Build number: R16NW.N950USQU4CRD7
Android Security Patch: April 1, 2018
Looking at AT&T's updated history logs, my Note 8 seems to be stuck with the last update being the May 15, 2018 update. I just realized this as I've been seeing people talk about updates received and some emoji feature - which I don't have. I keep checking my device daily and it continuously says my current software is up to date - no updates available. I tried using Samsung Switch on the computer and it also says my device is current.
Thought about doing a Format/Hard Reset and starting fresh... but would that help my situation to receive the latest update(s)? Not sure it would help at all or what to do in this case.
Any help is appreciated.
Thanks!

It appears as if it is stuck and doing a factory reset "format/ hard reset" will not fix the issue since it will report that it's still on the same baseband version.. What you have to do now is flash the most up-to-date firmware there is in order to get the stuff you want like the emojis.. I'm assuming you know how to use odin to flash firmware files? First you're going to have to download this baseband version N950USQS5CRG9 it's over 3GB in size and then after that's flashed you'll have to get this N950USQU5CRIA update which is 600MB and place it on your SD card and then boot into recovery mode and then select flash update from SD card and it'll all be done.
Also the way to get the 600MB update is easy you go to this website https://samsung.firmware.science and you scroll down some and the first thing you do is enter your phones model which is N950U and then under that you select the baseband version that you're currently on which is N950USQS5CRG9 after selecting that right underneath you'll see download for N950USQU5CRIA and that's the update firmware you put on the SD card!

Even if she isn't using an AT&T sim card, she needs to learn this process anyway because if she doesn't have an AT&T sim card she can't sit there and keep getting an AT&T card just for updates all the time that's why it's best if she learns the flashing process.

You'd have to be quick on every single flash but you COULD do it. Personally I would not recommend it. Doing a dirty flash that many times (it'll be a lot) is asking for trouble.

USE Verizon SIM

AT&T Note 8 - purchased directly from AT&T
Stock - no changes/modifications
Baseband Version: N950USQU4CRD7
Build number: R16NW.N950USQU4CRD7
Android Security Patch: April 1, 2018
Looking at AT&T's updated history logs, my Note 8 seems to be stuck with the last update being the May 15, 2018 update. I just realized this as I've been seeing people talk about updates received and some emoji feature - which I don't have. I keep checking my device daily and it continuously says my current software is up to date - no updates available. I tried using Samsung Switch on the computer and it also says my device is current.
Thought about doing a Format/Hard Reset and starting fresh... but would that help my situation to receive the latest update(s)? Not sure it would help at all or what to do in this case.
Any help is appreciated.
Thanks!

Just put any working Verizon SIM card ( borrow one from anyone ) and it will update your cellphone automatically, i did that with S8+ and Note 8 Both from AT&T, both AT&T logo gone but i got the update from Android 8 to 9, i'm assuming when ever you switch your SIM card to your company you will start getting the new updates with the logo from them again, let me know if this works, thanks.

hello. i purchases an At&t note 8 and paid for the unlock codes from AT&T themselves.
i popped in a new sim, brought it back to Africa where i work and ever since, it has refused to give me an OTA update.
Baseband Version: N950USQU4CRD7
Build number: R16NW.N950USQU4CRD7
Android Security Patch: April 1, 2018.
Looking at At&T website, other note 8 users and reading through Sammobile, I am obviously far behind on updates.
Can anyone help me fast track to android PIE?
Im so confused with the number of Firmwares out there. And considering i have had it unlocked, i do not know how to proceed..
Thanks in advance.

SM-A205U (MetroPCS) OEM Unlock

Hello,
Just wanted to share this with the community as I found this just yesterday. If you goto your settings and click connections then "More connection settings" towards the bottom there is an option for "Network Unlock". I did this like I said yesterday and it permanent unlocked the phone. I don't have any other SIM cards to try and see if it will go on a different network but just wanted to point this out to the community!

That's not an OEM unlock, you've only unlocked the SIM card lock.

Into the sun you go

I wondered if this was either effecting, &or blocking or stopping oem unlock from showing or being visible? Just a thought.

It's our specific model.
There are no 205u units in public domain that exist with an oem toggle.
It's disabled by default in the 205u source.

The only way this might be possible is with combination firmware but in all my searching so far i have yet to find bootloader 5 combination firmware ...
If anyone can find me a bootloader 5 android 10 combination firmware for the 205U varient i would be willing to see if there would be a way to get this rooted and bootloader unlocked

The combination file is from an older bootloader, so it retains the most recent bootloader to maintain integrity of the Qfuse.
That's kinda why we want the combination file for 10, the bootloader hasn't changed which means the file would be universal for anyone who updates.

S8+ g955f stuck at Samsung logo, bad flash

Hey everyone hope you're all well. I have an s8 plus that's not booting. Here's the events that transpired....
My nephew wanted it wiped so I went into recovery and it immediately started to install an update for some reason and wouldn't boot, so I told his brother to flash a stock ROM which he did and booted fine, but with one issue, it showed as 16gb instead of 64gb. At this point I downloaded a pit file and flashed it. I then flashed the stock ROM and it won't get past the Samsung logo.
This is the stock ROM I flashed, AP_G955FXXSADTI1_CL18920278_QB34109287_REV00_user_low_ship_meta_OS9
I'm guessing I need to flash the correct pit file and then the stock ROM?
Any advice would be appreciated
Thanks!

Flash full firmware not just AP file. Flashing AP file only is more than likely the reason for difference in storage size.
No need for pit file. If it is needed it can be exacted from the firmware that you have downloaded.

I did flash all 4 files not just the ap. I only wanted to show the version etc
Now when I try to flash Odin says failed

What Odin version are you using
What errors in Odin
Can you post a copy of download mode and error in Odin

Absolutely. Odin3 3.13
I've also attached a picture of the rom files. For some reason there's 2 CSC files. I tried using both but same issue.

1. CSC files
CSC file will wipe all apps and data ( same as out of the box )
HOME_CSC file will keep apps and data
2. The reason Odin is failing is you are trying to downgrade your firmware.
You are on bootloader version 11 the firmware you are flashing is on version 10. You can check in download mode to check bootloader version. There will be a line saying AP SWREV. The number after the letter B is your bootloader number.
Also in download mode down the bottom ( in red ) will tell the reason why it is failing.
You will have to find what firmware was flash before or wait for samsung to upgrade it's bootloader version.

I see. The strange thing is that this is the firmware that my nephew flashed after it initially failed and it flashed with no errors. The errors only occurred after I tried to flash the pit file, which I'm guessing was a big mistake.
Right so I need to find a stock ROM with bootloader 11. Is there an indicator in the filename that will tell me the bootloader version?

Why do I get this message every day? Throw the darn thing out already.

Flashing the pit file should only fix the partition size and is generally not needed. Flashing the wrong pit file will cause issues. Doesn't effect the issue of trying to downgrading firmware.
As far I'm aware official samsung firmware is up to bootloader 10. Firmware should be downloaded from official site like sammobile or updato or pc apps like samfirm or frija
In regards to bootloader version ( official firmware ) it can be found in the firmware being downloaded.
Bootloader version will be the fifth number/letter from the right of firmware name.
eg:
G955FXXSADTI1 - A - bootloader version 10. I'm assuming the next bootloader version number will start with B
G955FXXU9DTF1 - 9 - bootloader version 9
The higher the number the higher the bootloader version.
Due to samsung anti róll back bootloader version cannot be downgraded.

Buy your nephew a damn phone

I did buy him this phone. Just because it's a little messed up right now doesn't mean I should just thrown it out. This entire forum is dedicated to invigorating devices and keeping them going. XDA didn't accept the philosophy of throwing out devices when they can be repaired. I've been here long enough to know that.
Ffs people are still developing for the hp touchpad and m7 Windows devices!

Thank you very much for your replies. It's very much appreciated mate.
I did flash the pit file and subsequently got errors in odin. I want aware that I was trying to downgrade. I've download from official site and will try flashing today.
Again thanks for the help. Been a while since I've had to do this lol I think the last device I was rooting and roming was my note 3! The support for it is still going strong though!
Cheers

I guess at some point its best to move on. My grandsons S8 had the digitizer go bad tried to fix unsuccessfully bought him a used on on fleabay for $150.

@spawnlives thank you very much. Phone is back up running perfectly. Appreciate it mate
@pego99 that's a judgment call. Fair enough buying an s8 screen is 100 and new is 150 it would be reasonable to buy a new device. However this was a software issue which costs nothing to fix. Your posts in this thread are redundant and useless.

OK it costs nothing money wise but time but time is valuable. i.e. If you spend the next 6 months on this has it cost anything? Nope no out of pocket but a lot of time and nephew has no phone to use. BTW If you bought the phone in working condition how did it get screwed up anyway?

It took less than an hour to fix this phone, that's a cost I can stomach.
if you had actually READ the post instead of commenting asinine remarks them you would know how the phone for corrupted in the first place.
