[Samsung Galaxy S10e Guides, News, & Discussion] iBowToAndroid:
For those who don't know, G970U is the model number of all of the US carrier versions of the Galaxy S10e. The G970U1 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. 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 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 SamFirm/Frija, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model - so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit SamFirm/Frija.

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, I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.

Happy flashing!

(Quebec tends to be the fastest download mirror, if it gives you that option)

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.

NOTE: With initial release, HOME CSC was not included by default, so I created it myself. Should flash fine, but until noted by someone in the thread, it has not been tested.

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

- Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.

- For identifying USERDATAS, and to know what region/CSC to use in SamFirm/Frija:

AIO = Cricket (not available via SamFirm/Frija)

ATT = AT&T (not available via SamFirm/Frija)

BST = Boost Mobile

CCT = Xfinity Mobile (Comcast)

CHA = Spectrum Mobile (Charter)

SPR = Sprint

TMB = T-Mobile

TMK = Metro PCS

USC = US Cellular

VZW = Verizon (available via SamFirm/Frija, but Manual Entry is required - Auto will not work)

XAA = U1 firmware

- the correct procedure for switching from one carrier's firmware to another is:

1. Flash full U1 firmware package including non HOME CSC

2. Upon boot, insert a SIM of the carrier whose firmware you want

3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it

4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want
