It looks like nobody has the demo firmware for the original S8. I have found some files for S8+ XU though

---------- Post added at 08:08 PM ---------- Previous post was at 07:59 PM ----------

There's also the documentation for the live development unit on that server here: http://14.63.213.86/upload/2017/03/30/12/Setup_Guide_For_Galaxy_S8_LDU.pdf slightly smaller than the RDU pdf

Amazingly, that server has directory listing enabled. Looks like it has a bunch of stuff about demo units.

Found this APK http://14.63.213.86/upload/2017/03/30/32/SamsungRetailMode_Global_Dream.apk

Just don't install it on your S8... Seems to be impossible to uninstall
[Samsung Galaxy S8 Guides, News, & Discussion] V0idst4r:
I didn't realise easy-firmware had 950XU as well. Here: https://easy-firmware.com/index.php?a=browse&b=category&id=26218

And about flashing normal non-demo firmware to it, I found a thread about a S7 LDU: https://xdaforums.com/galaxy-s7/help/removing-retail-mode-s7-live-demo-unit-t3375740

It might be the same for the S8.

The second post mentions some files that need to be removed from the normal S8 firmware so that in the end they are still the same ones in the demo firmware. You don't need cygwin like that thread mentions though. I would just use 7zip and winrar. Extract the .tar/.tar.md5 with winrar and make it a tar again with 7zip.
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
Because I dont have money and its not on Samsung Servers yet, does someone want to buy this and post it for us. https://easy-firmware.com/index.php?a=browse&b=category&id=26217

On second thought, does anyone with a premium account want to download and upload it for us, it would be very nice. I would love this. Its the combination firmware, so a factory binary for the G950U1 firmware.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
i think i have AQE3 for the 955U1
[Samsung Galaxy S8 Guides, News, & Discussion] unitz0mbie:
how? im on g955u1

---------- Post added at 10:33 AM ---------- Previous post was at 10:33 AM ----------

how? im on g955u1 but mine ends in AQDC
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
its the factory binary firmware

---------- Post added at 09:59 AM ---------- Previous post was at 09:57 AM ----------

i was replying to the other persons post which is for G950U1 AEQ4 and I was saying I have AEQ3 combo firm for the G955U1.. nothing was said about me being on stock AEQ3 U1 firmware lol..

hell, im on stock vzw firmware atm
[Samsung Galaxy S8 Guides, News, & Discussion] V0idst4r:
What device is the G950U1/G955U1?
[Samsung Galaxy S8 Guides, News, & Discussion] TheBigEasy88:
For those looking for demo/retail modes or just interested in what this entails - http://www.retailsamsung.com/

There's a user guide section, that includes a few powerpoint presentations, that can 'enlighten' you as to what retail mode is. For the record, there isn't anything special or 'cool' in this mode so I'd stay away from installing. If you're like me, and like to know everything that you possibly can, then the user guides make for a quick study.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
lol... its the US unlocked variant sold by Samsung.. the actual XAA device
[Samsung Galaxy S8 Guides, News, & Discussion] V0idst4r:
I'm assuming it doesn't have an unlocked bootloader either?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
lol highly unlikely.. i dont believe it to be much dif. than all the other combo firms we already have..

only good to remove frp and other minor things like that.. i didnt even bother flashing it because theres no point lol
[Samsung Galaxy S8 Guides, News, & Discussion] webdork:
There's no bloatware on the xaa... So that's nice.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
lol... not sure what you mean.. someone posted about COMBO FIRM.. not any stock firmware.. lol he requested someone purchase combo firm and everyone is postin thinkin hes talking about a stock every day firmware lol

but yes, the combo firm has 0 bloat.. hell doesnt even have the Play Store lmao
[Samsung Galaxy S8 Guides, News, & Discussion] V0idst4r:
There's not even a dialer
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
i think there is.. well theres a keypad to input dialer codes at least haha i guess theres always a chance it has more priveleges but i highly doubt it based on the other combo firms..

it is pretty useful tho for those who mess with drk, imeis, frp etc.. also if they start incrementing bls would be good to have updated combo firms of course..

it seems they update combo firms before actual stock firmwares lol
[Samsung Galaxy S8 Guides, News, & Discussion] ashyx:
But it does have an app that allows short codes to be entered.
[Samsung Galaxy S8 Guides, News, & Discussion] scoutconnor1:
I have a T-Mobile GS8+ that I flashed over to the unlocked version of the firmware.

I am trying to flash back to the TMo firmware because it supports their new RCS features but I seem to be hitting some roadblocks.

Every time I try to flash the firmware (https://xdaforums.com/tmobile-galaxy-s8+/how-to/sm-g955u-odin-firmware-g955usqu1aqd9-t3593600) Odin fails or gets stuck.

Has anyone successfully flashed back to stock TMo firmware? If yes, would it be possible to provide some assistance?
[Samsung Galaxy S8 Guides, News, & Discussion] V0idst4r:
The unlocked firmware doesn't have RCS? News to me

---------- Post added at 07:31 PM ---------- Previous post was at 07:28 PM ----------

32GB or 64GB?
[Samsung Galaxy S8 Guides, News, & Discussion] scoutconnor1:
atm RCS is carrier dependent so I don't think it'll pick up the TMo RCS being that it thinks it is the 955U1 model.
[Samsung Galaxy S8 Guides, News, & Discussion] Harry44:
Are you using stock ODIN to flash or a modified/patched?

Use the latest stock ODIN. And report back.
[Samsung Galaxy S8 Guides, News, & Discussion] scoutconnor1:
3.12.5? If there is a more current one, I couldn't find it during my initial troubleshooting.

I've tried both official and the Prince patched version.
[Samsung Galaxy S8 Guides, News, & Discussion] ruvort:
I don't mean this to sound rude, but you "lol" a little too often.
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:

[MENTION=3812611]elliwigy[/MENTION] what service are you using? I'm thinking about going back to stock VZW/VZW/VZW. My only concern is band 12 for Tmo support but I've live w/o that forever so I can continue to if necessary. Lol
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
except it doesnt need correction, the way i type is just fine.. sorry if it bugs you lol

---------- Post added at 08:34 PM ---------- Previous post was at 08:33 PM ----------

i use verizon on vzw/vzw/vzw currently for gear vr to function
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Oh I didn't know you were using Vzw. I thought you were either on Tmo or ATT. Lol Guess you just wanted to debloat huh?
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:
Step 5... Which HOME_CSC did you use? G950W or G950U?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
lol vzw ftw.. best network ever.. and not really, i am on stock vzw fully now, not even on the U1 as my gear vr didnt work..

i essentially debloat my own roms with package disabler.. the U1 rom just has a few less apks to disable but other than that doesnt make a huge difference to me outside of the splash screen on initial boot
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Yeah that's what thinking too, just going to disable the vzw bloat
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
there is no vzw home csc.. each firmware file will have a regular csc and a hoke csc included (except the combo firms)

i assume he means the home csc that is with the firmware files you are flashing to your phone instead of the regular csc that is in that firmware
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
[MENTION=3812611]elliwigy[/MENTION] did you flash everything except the non-home CSC to get back to VZW? I'm going to do it now. Thinking about flashing AP, BL, CP, Home_CSC and userdata (UMS slot?)

So I flashed everything with home CSC but my Odin's won't allow me to flash userdata, both my prince version and the regular version. Got to XAA/XAA/VZW. Going to try non-Home CSC right now.

Grrr, I flashed userdata in AP slot and while I do have the Vzw bloat, my device is still XAA/XAA/VZW...
[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
I'M on U1 with no issues using Gear VR. What problems were you having?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
it wouldnt connect to the server.. that was prior to the actual release of the U1 dwvice so if its working now it was simply due to the phone not being out yet.. good to know it works now!
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Hey, how did you get your device back to completely stock VZW? I can't seem to do it using the latest VZW file. I'm stuck at XAA/XAA/VZW
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
i flashed probably 20 different things to be honest.. next time i mess my phone up I will keep track of my steps.. maybe ill do this tonight if itll help ppl
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Lol, that's exactly what I'm doing, going back and forth, back and forth. Maybe I should flash the combination firmware, do a reset or something of that nature, then flash the VZW stuff including userdata in the AP slot at the end to see if that'll do it.
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
Flash instructions on post three here. https://xdaforums.com/tmobile-galaxy-s8/how-to/eng-boot-root-t3608353
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
that doesnt work lol.. i could never get passed permission denied and that doesnt put it back to vzw/vzw/vzw to my knowledge..

either way i never got past permission denied using that method as others have the same issue.. i posted that issue a while back.. i tried multiple combo firms and multiple eng boots and every single time got permission denied
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Yes I was thinking about doing that after I tried what I mentioned earlier.

---------- Post added at 03:40 PM ---------- Previous post was at 03:39 PM ----------

I'll give it a try. Lol
[Samsung Galaxy S8 Guides, News, & Discussion] jaypr9:
How long ago did you flash U1 with working VR? I also had tried it a few days ago but had no luck with Gear VR on ATT. So i went back to ATT firmware. If its working now I'll go back to U1 so I dont have all the ATT bloat.

BTW what was the method for getting all the ATT features like volte, etc without the actual bloat?
[Samsung Galaxy S8 Guides, News, & Discussion] jellomonster54994:
stock tmobile original what firmware can i install to have it unlocked?
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:
None yet
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
you cant.. you need to use their unlock app.. flashing firmwares does not magically unlock the device as stated many times in multiple threads
[Samsung Galaxy S8 Guides, News, & Discussion] dharmastation3:
And...so far I haven't seen anyone flash the "unlocked" firmware on a T-Mobile phone and be able to revert back to 100% stock. So if you plan to unlock it, don't try the unlocked firmware. It borks the unlock app. You'll be stuck.
[Samsung Galaxy S8 Guides, News, & Discussion] underground9:
Does anyone have a sprint omadm notification saying 'checking device status' after flashing G950U1?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
if its similar to vzw then you 100% can go back to 100% stock.. i did it on vzw, should be the same
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Yeah I had that but it disappears without doing anything or erroring out so I wouldn't worry about it.
[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
I flashed the 955U1 Verizon software from Updato site about a week and a half ago. I was in XAA/VZW/VZW, factory restored in settings and flashed BL, AP, CP and non-home CSC.
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:
EUREKA!!

This worked... ended up with XAA/ATT/***

...but after factory reset from settings menu, it went to ATT/ATT/***. So the encrypted userdata is keeping it from updating the CSC section.

Tried it again (skipping a few steps)...

1) flashed G950W (XAC) w/CSC (not HOME)

2) setup with encrypted data (require pin on reboot)

3) flashed G950U w/HOME_CSC

4) PROFIT!! -- Ended up with XAA/ATT/*** -- VoLTE works! No bloat! No AT&T-spec status bar icons!
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
lol really.. you had to post in multiple threads haha, good job tho, enjoy bloatless
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:
Haha... so many people want this result, especially with at&t because volte doesn't work with at&t on g950u1 like it does for other carriers. Been following several threads and finally found someone who remembers how they ended up at xaa/carrier/***.

Shared in multiple places because I've seen it asked I multiple places. ?
[Samsung Galaxy S8 Guides, News, & Discussion] Joell27:
So what exactly is being unlocked (simcard or bootloader)? I really want to flash the sound mod. Please help me with the steps needed to do so. I am currently running a stock tmo s8.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
lol you cant.. theres no root or unlocked bootloader at all yet
[Samsung Galaxy S8 Guides, News, & Discussion] Skyrocket2Paradise:
Hellll ya! I've been hoping someone would find the right combination for this ha do you have video and WiFi calling as well. Hopefully there's a way to update in the future without wiping
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
sim unlocked means u can use on other carriers.. sim lock you can only use it on tmo in your situation..

unlocked bootloader means we could flash a custom recovery like twrp and root our devices and flash mods etc... no USA variants have this as of this writing
[Samsung Galaxy S8 Guides, News, & Discussion] Joell27:
Thank you
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
You flash U1 then after reboot boot back into DL mode and flash user data in ums slot. I have all the goodies and no bloat on att.

[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
no, just flash 955 u1 firmware in comsey odin... whats the point in making a guide for that lol
[Samsung Galaxy S8 Guides, News, & Discussion] ashyx:
People keep mentioning flashing the USERDATA partition to gain extra features. What extra features? It contains nothing but carrier bloat as far as I can see?

It's the CSC that decides the device features based on carrier/region.

I even posted screenshots of the directory listing way back.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
only thing i can think of some carrier bloat apps are required to be installed for certain features to work? who knows lol
[Samsung Galaxy S8 Guides, News, & Discussion] vboyz103:
Right, and TMO userdata is 1.6GB that's a lot of bloat.
[Samsung Galaxy S8 Guides, News, & Discussion] jaypr9:
When I flashed just flashed the u1 room I ended not even seeing the software revision thing. It was completely missing, no att/ anything. Everything worked though. Well I didn't check if volte was there and gear VR didn't work. I'm going. To try later and see if I can get volte with gear VR working.
[Samsung Galaxy S8 Guides, News, & Discussion] XxCyberHackerxX:
I think it's the protection feature introduced in marshmallow. I don't think there is a way to bypass it.

[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
I'm back on the same boat as you, U1 firmware with no software listing the XXX/XXX/XXX format on a Vzw device. Have VoLTE and Wi-Fi calling, Samsung Pay working. Do not have a Gear VR so can't attest to that (yes I bought it on launch day and did not pre-order, impulse buy... lol)
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
you can launch the gear vr wizard using quick shortcut maker on play store
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
Has to be more than carrier bloat, I flashed U1 and upon boot there were no ATT features or apps. I flash user data in the ums slot and the phone now has the att splash screen, one att bloat app and has all the calling features also, volte, video calling, wifi calling ect. Plus 1.6 GB is the size of the whole AP/system used to be. What program did you use to Snoop around and inspect the user data?
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Yup, getting the network connection error. Oh wells, not currently interested in vr so I'm still good for now.
[Samsung Galaxy S8 Guides, News, & Discussion] ashyx:
You flashed USERDATA alone or with the rest of the firmware?
[Samsung Galaxy S8 Guides, News, & Discussion] Sam3gX:
I have the same results as him. I only flashed USERDATA. Volte still wasn't working for me for some reason.
[Samsung Galaxy S8 Guides, News, & Discussion] jawonder:
