G975U and G975U1 Firmware Links and Flashing Discussion Here

[iBowToAndroid]

For those who aren't already aware, G975U is the model number of all of the US carrier versions of the S10+. The G975U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.

Manual Odin flashing is designed for those who:

- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)

For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via the various firmware download tools posted here on XDA like SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit the firmware download tools, so that's where my files come from.

This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.

Happy flashing!

U firmware: https://www.androidfilehost.com/?w=files&flid=290649
U1 firmware: https://www.androidfilehost.com/?w=files&flid=290650

Notes:

- I compress extra small for space and bandwith savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc

- I remove the .md5 from each file solely for faster flashing (Odin won't check the file integrity without it). Rest assured, the files are perfectly fine and safe - Odin has a million safechecks built in.

- My naming method for folders is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.

- HOME CSC file keeps data intact; using the other CSC will wipe data. Any zips with "wipe" in the title do not have a HOME CSC included.

- I have identical threads for the S10e and S10 as well

- the correct procedure for switching from one carrier's firmware to another is given in post #25

- You can get USERDATAs from SamFirm for everything but AT&T and Cricket- those files will never be on SamFirm. So in addition to the 5 piece firmware, I'll try to always upload one USERDATA per bootloader increment for those carriers.

- For identifying USERDATAS, and to know what region/CSC to use in the firmware download tools if you're downloading yourself:

AIO = Cricket (not available via firmware download tools)
ATT = AT&T (not available via firmware download tools)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon
XAA = U1 firmware

This is looking great, was about to pre-order the T Mobile variant, when I remembered that they disable the (Data) Quick Toggle and I have to fiddle around to turn it off, Well, Not the case with the Unlocked version, at least on my Note 9. Anyways, this will come in handy, thanks!

Hopefully One UI stays the same. You're welcome

Good to see and will be a good place to hangout! ?

Loved your dedication to uploads on the 9+! Glad to see you here as well! I preodered my ATT 10+ yesterday. Got my mom and two daughters the 10+ / 10e also. Happy to see you'll be providing firmware for the "E" also!

 

[iBowToAndroid]

Build SBA added.

Only CCT, VZW, and SPR USERDTAs (for now), but it can be flashed to any S10+

So I flashed this on my new U1 and went to U firmware. My Wifi didn't work after this. I can't connect to any Wifi network... I will try going back to U1 and see if the issue is fixed. Maybe I have a defective phone?

Hmmm that's weird. I'm assuming you wiped?

G975U and G975U1 firmware is now live and downloadable in SamFirm. Getting U1 requires manual entry - Auto will not work. U firmware is up for these carriers:

Xfinity Mobile
Spectrum Mobile
Sprint
T-Mobile
US Cellular
Verizon (have to use Manual entry - Auto will not work)

So going forward, I'll only be adding full builds if I can get them before they hit SamFirm, and only if there isn't build for that month already (eg. I won't add any more February builds since SBA is already up.). I will try to stay up to date on USERDATAs for AT&T and Cricket, since AT&T won't let their firmware be put on SamFirm.

Thank you for this. Just flashed my U1 to TMB SBA for video calling feature.

Is it? I'm not seeing anything.

Not sure what that link is, but U1 is available via the SamFirm tool. I did forget to mention that you have to use Manual input, so i'll edit that part

That's for auto download. How'd you get the PDA/CSC/Phone?

Manual input, like I said. You have to type in the builds manually

Yes, I realize that. G975U1UEU1ASAU/G975U1OYM1ASAU/G975U1UEU1ASAU

Where are you pulling the values from? Do you have the physical device?

No. I'm getting them from the place where I get my firmware files from

 

[vimto25]

I have a question and I hope someone can help me. I just purchased a s10 not the plus. And its unlocked which is great but has three UK branding on boot up ect..,
Is it possible to remove this maybe install another rom via oden? And it wouldn't void warranty or enable a security problem on the phone? Any help would be much appreciated

 

[todd3835]

Guessing ATT is late to the party as usual with no ASAB userdata yet? Doesn't appear they've pushed it yet ?

This thread is for U models (Qualcomm). You need to find a thread about the F models (Exynos).

Anyone can flash any update - USERDATA isn't required unless you're changing from U1 to U, or from one carrier to another.

Ah ok. On my S9+ I did some Odin flashing and even though I was on the att release, I wasn't getting OTA's. It was odd. Only way to restore OTA updates was flashing with ATT userdata.

On a side note, ATT has pushed the ASAB update for both the S10+ and the S10E.
