Hi there,
Combination files are basically used for testing purposes in the Samsung devices. These files are there to make sure that the functionality of your device is error-free before making its final release. These files are created by Samsung company and are found in only their devices.
Coming to next part, your question didn't exactly clear the problem you are having with these files? If you are missing them, you can download them by Google for free. If anything else is bothering you, do specify the proper details regarding the issue.
Thanks

Does someone know where i can get the Combination for G955FXXU3CRGH ?
Thank you!

If you have combination firmware, then no need to buy any paid tool to remove frp lock, resolving issue of your device.
simple flash with COMBINATION FIRMWARE, and after that flash via STOCK ROM,
STOCK ROM: is a default firmware, that is built in by device manufacturer. that also can be downloaded from forums or by google it.
Combination ROM Advantages:
Its help you to repair imie number in some models like S7 S7 Edge S6 S6 Edge…
Its very useful in bypass samsung account in too many models.
Its very useful in bypass Google account in too many models.
Its very useful for downgrade in some models.
Its help you to enable usb debugging.
its help to remove any security FRP / Reactivation Lock from Samsung like 2016-2017
You will flash your device via Odin Software, which can be downloaded from here

I have the following phone that I'm trying to get FRP bypass: 6.01. (October 2016) Android Marshmallow / Galaxy S7 SM-G935V
I flashed combination ROM onto it already, so all I have to do now is flash the original stock firmware onto it to complete the FRP bypass? There's no need to make that OEM Unlock option show up?

I know this is an old post but answering for people who has the same question.... oem unlock is to be able to flash non official files like twrp or a modified firmware. to flash stock firm just flash with odin and that's all.

Welcome to the Idiot Club(tm), number one idiot (me) here did the same damn thing. Thought gee, why do I need to keep allow OEM unlock on?...
Welp... got my answer.
Its not a huge deal to flash stock firmware but its still annoying.

idiot no 2 here. I just turned off OEM and rebooted the phone. duh! Now i am downloading the stock ROM at 20KB/s

For anyone wantying to download it a little quicker use samsung Kies and fill out the information after clicking tools> Firmware upgrade and initialisation, slightly bigger file but much quicker download lol.

Sorry for the late reply, but unless you can somehow check "OEM Unlocking" without actually turning the phone on(doubt it's possible through ADB with storage Encryption) , the only way to get rid of this issue is to wipe data.
And if you go to your temp folder the "AP, BL, CP, CSC, HOME_CSC (use this CSC to not wipe)" and you can use them in ODIN.

thx for the trick with flashing HOME_CSC instead of CSC. I was so dumb to disable OEM-unlock and my G930F did not boot anymore. I was very frustrated because like 95% on the internet say its only solvable with loosing all data. With flashing a stock rom with the HOME_CSC all data survived!

how to fix (Custom Binary Blocked by FRP Lock) if I cant access my phone and go to developer mod?

Thanks for the reply. I searched on xda and it seems it will most likely trip knox. Is it possible with the official firmware from sammobile using odin?

Partcyborg rom does not trip knox as it does not unlock the bootloader

Yes as the boot-loader is not unlocked Knox is not tripped on snapdragon S8s we do not have twrp or custom roms besides the one....
But as we have locked boot-loaders that is a perk to it as Knox is nearly untrippable

Doesn't root break samsung pay though? That ROM comes pre-rooted.

That it does it does break pay

I have never went through the csc switch so i do not know the exacts to it but it could be as easy as just flashing the u1 firmware and which you pick determined by which bootloader your on now

Yeah, Samsung Pay is used on a daily basis for me. Unfortunately I can't use a custom ROM if it's rooted

Most people go from W to U not the other way but I dont see why it wouldnt work

I have tested some pretty righteous stuff and still no knox trip Infact mine is currently on its way to the repair center for stuff I flashed just testing some theory out..... but it was major stuff not just with the rom or anything I dont want to scare you....

Trying this
Hi there,
So I am trying exactly this (flashing an SM-G955U with firmware for SM-G955W). My reason for doing this is I am hoping that it will improve the reception since SM-G955W is the Bell Mobility firmware and I am on Bell Mobility in Canada.
I have tried Odin 3.13.1 and 3.12.5. I got my firmware from SamMobile.com. This is the link to the exact firmware I downloaded:
https://www.sammobile.com/firmwares/galaxy-s8-plus/SM-G955W/BMC/download/G955WVLU5BRG4/230118/
I put my device into bootloader (power off, power on with Power+Bixby+Volume Down) and when I try to flash I get FAIL! SHA256 is invalid in Odin.
Any suggestions? Am I missing something?
I do not want to root my device. Just flash with stock firmware to re-brand it for the carrier I am using. I want this phone to be as if I purchased it from Bell directly if at all possible. Or should I be using the generic "Canada (XAC)" firmware instead of the BMC firmware? I can get the XAC firmware here:
https://www.sammobile.com/firmwares/galaxy-s8-plus/SM-G955W/XAC/download/G955WVLU5BRG4/230670/
OK, slight update on this. If I use the PrinceComsey edition or Odin found here:
https://drive.google.com/file/d/1dzNPNe2SPVPr2FR1R9aPmbiENajzRsMN/view?usp=sharing I can get it loading but it loads to my phone real quick (doesn't seem like it transfers everything) and then reboots and my phone is still running the same firmware (with all my apps installed, etc) as before.
Thanks,
The Fish

I recently went from bootloader 5 G955u to g955w. Phone was carrier unlocked. Need a combination rom and a rom from your desired canadian cell provider with same bootloader version.
Follow the carrier switching steps. Then follow the flashing standard firmware steps.

I am really interested in how you did this. I keep getting a fail at step 13 in the "Carrier Switching" section. The only thing I can think of is that I am using 3.13.1 and his guide says (under step 6) that I should be using Odin 3.12.7 but I am using the one from the download links the author provides in his post.
The failure message I get on my phone itself is SW REV CHECK FAIL: [abl]Fused 5 > Binary 2 which makes me think this has something to do with the bootloader being at version 5?
Any tips would be greatly appreciated!!

OK, just to answer my own question(s) and document this for Google. I successfully carrier switched my SM-G955U to Bell and it now reports that it actually is an SM-G955W.
You need version 5 of everything (boot loader, factory ROM, HOME_CSC, etc). You also need to use the new “3b” Patched Odin 3.13.1 by realbbb available here:
https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572. Otherwise I could not flash the HOME_CSC file.
Basically you can follow the instructions here:
https://forum.xda-developers.com/galaxy-s8+/how-to/snap-guide-flashing-standard-fw-carrier-t3627255
But replace the references to Prince Comsy Odin with the 3b patched Odin. In fact I think you can use 3b patched Odin in place of “standard” Odin as well.

Galaxy S7 G930F bootloader problem

Helllo to everyone. On my galaxy s7 I have officail OTA updated 8.0 Oreo (DHR), never before I did not installing any ROM-s, root or something like that. This is my first experience with flashing. Yesterday I tried to install official 7.0 android (DHR) from Sammobile but after putting phone in download mode and start operation on Odin I get these errors.

After serval tries with different versions of firmware( oreo btu, oreo dhr....) I gave up. Before putting phone in download mode I enabled USB Debugging, but saw on Internet that many people enable OTA unlock (bootloader unlock) also. Should I enable OTA unlock or not because Samsung says that phone will lost all security features like samsung knox, samsung pay etc.. I flashing official ROM not some custom ROM and everything should work corectly without enabling bootloader unlock but doesn`t work, always I get that fail. Some ideas?
Sorry on my bad english I am not English native speaker and I hope that my problem is clear to understand. Thanks in advance

Bootloader already unlocked but I cant flash it? [Solved: Phone is SM-G970N not SM-G970F]

I got an s10e from an ebay refurbisher but couldn't get OEM unlock to show up no matter how many times I did all the steps (connect wifi > change date > disable auto updates in dev options > tap download updates etc). At some point, I happened upon a tutorial that showed how to unlock the bootloader with computer usb + volume down + bixby on boot. To my surprise, it only gave me the option for *locking* the bootloader.

The OEM unlock option still doesnt even show up in the options however, not even grayed out. I do wonder if the refurbisher flashed their own vanilla rom onto this since it says the binary is custom . I imagine this is probably good to go?
I then tried to flash both stock firmware and that same firmware flashed with magisk with no success. I want to install /e/ android onto this, which like a lot of other rom installation guides, explictly says that I should update to latest firmware. In this case, the latest android 11 firmware available, or else downgrading from stock 12 to /e/ 11 could cause problems (according to the /e/ instructions).
Odin just didnt work. I tried multiple usb ports, multiple firmwares, multiple cables, multiple versions of Odin. The only consistent behavior is that trying to flash using odin freezes on startup, with a red error text showing up on the download screen. Using home CSC makes a SECURE CHECK FAIL : (BOOTLOADER) error show up, using factory wipe CSC makes a SECURE CHECK FAIL : (PIT) error show up. Some articles say to try using the pit option, but the odin warning of DO NOT USE THIS TAB has me apprehensive. This is as far as I've gotten.

So the problem turned out to be that I was sold the wrong product. Not cool refurbisher, not cool, maybe not even legal. Anyways, as you can tell in the download mode, this is not the SM-G970F that I was sold, its a SM-G970N. Still runs an exynos chip, but it's a korean model. Not certain how the refurbisher got the phone to show up as a F skew without the "THIS ISNT OFFICIAL SAMSUNG FIRMWARE" warning and all that.
Flashing firmware specificaly for the N skew worked just fine. I flashed the latest verison of android 11 KTN firmware for the phone and it worked, just needed a factory reset from recovery after I flashed the firmware. After I did so, the OEM unlock option showed up in developer options, already greyed out and turned on.
I next decided to try flashing /e/ android using the build madefor the F skew, and it worked without any fuss! I am now happily running a custom firmware like I planned to do when I bought this. I may get a weird boot screen in korean, but that's the least of my concerns.
