no and no.. you can disable most apps but cannot remove them to my knowledge and if the volume mod is done by modifying anything protected you will get a permission denied as we do not have a useable root
[Samsung Galaxy S8 Guides, News, & Discussion] Bladescarr:
Has anyone figures out how to remove all carrier bloat and branding from the phones yet?

I would like to have a debloated version of the phone, but stay unrooted.

Can this be done yet?

Thanks! :D

Flashfire is likely detecting permissive mode as that is what it needs if using anything other than SuperSU to gain root.

no lol.. u need root for that and the factory binary will remove EVERYTHING and render phone unuseable on any networks

[Samsung Galaxy S8 Guides, News, & Discussion] ashyx:
I've never known a combination firmware to not have all the required files including the bootloaders.

I have just downloaded the combination firmware and I can see 2 bootloaders in elf format. abl.elf and xbl.elf.

abl.elf probably the equivalent of aboot.mbn and xbl.elf equivalent of sbl1.mbn.

It wouldn't make sense to have no bootloaders in the factory firmware.

I'm also assuming that the AP part of the stock firmware has a metadata folder located inside, which explains why the boot.img only works when flashed with the rest of the AP images and not when flashed on its own, as that folder has a ramdisk and some other data related to flashing the boot.img.
[Samsung Galaxy S8 Guides, News, & Discussion] TimelessPWN:
Correct the AP has meta-data in it, we thought that the abl.elf was the equivalent of the aboot.mbn but we were unsure
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
gotcha.. but in all honesty, even the aboot on factory firm has secure download enabled so wouldnt really matter anyways correct?
[Samsung Galaxy S8 Guides, News, & Discussion] ashyx:
All qualcomm devices have secure download whether the bootloader is locked or not and doesn't affect flashing of unsigned images.

It's the bootloader itself which checks the signature of any firmware binaries being flashed. Unlocked bootloaders have this check, in what I would call passive mode. It checks the existence of a signature but does not reject anything without out one.

You are correct however, even the factory bootloader is locked.

I have a feeling the full eng binary will again be leaked for the S8.

There is a thread in the s8+ section with flashable csc zips. But I don't know if s8+ csc will work on s8.
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
How do you do this. Can you please tell me.
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
Ok so just to test it out, I flashed T-mobile firmware, AP,BL,CP,CSC,Userdata in ums. Now I am back to SM-G950U and have Service provider SW ver. in settings, and it is XAA/XAA/USC since it was US Cellular to start with. I have a pay as you go T-mobile sim not activated in it, so can't test much. Have a couple t-mobile apps, lte, gsm. Put my cricket sim in and works fine.
[Samsung Galaxy S8 Guides, News, & Discussion] denson9874:
Download and flash XAC firmware and flash G950U firmware afterwards. It will recognize your T-Mobile S8/S8+ and change the code to XAA/XAA/TMB
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
I did that. It works now! Thanks!

everything is fine, its faster, bloat free, better battery, better performance. Everything is better but I don't like the icons as much. Whatever, I can get over it. Everything is faster.
[Samsung Galaxy S8 Guides, News, & Discussion] Bladescarr:
Hey, thanks for all the info, but what exactly do you mean by the icons are different?

They look different?

Can you apply the default icons through the theme store?

Thanks! :D
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
not the app icons, i mean like LTE and signal and wifi calling. They are just a bit different. Nothing big.

[Samsung Galaxy S8 Guides, News, & Discussion] Bl00dRunzC0ld:
What does your software version say? I just flashed TMB firmware over my XAC firmware and my software version says XAA/XAA/VZW

Edit: I should say I'm using the VZW S8+. While on the XAC firmware I didn't have VoLTE, calls would drop the signal to 4G, now I have LTE+ up top and it drops to LTE while on a call. Data speed is still around 35Mbps for me, but that's what it was on XAC. I can't access the dialer code service menu to check what bands are available, so I don't know if I lost bands since it says I'm XAA/XAA/VZW now.
[Samsung Galaxy S8 Guides, News, & Discussion] denson9874:
Just want to make everyone is aware of how this XAC and Multi-CSC firmware work. If your device is VZW, AT&T, T-MOBILE, etc originally, and you flash XAC firmware, your device will be 100% XAC. If you flash Multi-CSC firmware, i.e. G950U firmware, your device will not magically forget what it originally was. Whatever the device was originally will be altered by the XAC firmware but the Carrier Code is depended upon its original firmware. So, in other words:

VZW: XAA/XAA/VZW

ATT: XAA/XAA/ATT

TMB: XAA/XAA/TMB

You get the idea. So as of right now, what you started with will be what you end with, only slightly different thanks to the XAC firmware. No need for members with different carriers to compare if they have different carrier S8/S8+, because they are going to have different Product Codes if the are from different carriers.

Back to the original topic. what are you, crazy? (boatloads of sarcasm)
[Samsung Galaxy S8 Guides, News, & Discussion] Bladescarr:
I was wondering, would anyone be able to post a picture of the app drawer on the XAA firmware? I was wondering exactly what all the preloaded apps and such on it are.

Thanks!
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
its almost exactly the same, but all apps are uninstallable besides Facebook. That we can only disable. It is not had at all, its better.

[Samsung Galaxy S8 Guides, News, & Discussion] razrlover:
Sorry if i missed this on the thread already,

Exynos phones have the ability for VOLTE and wifi calling?

Seems that is snapdragon only i thought, so that would be a definite downside for me. Obviously the positive side of unlock BL and more but week signal or no signal would be a killer.

If anyone can verify that. Thanks

[Samsung Galaxy S8 Guides, News, & Discussion] denson9874:
Well essentially they are going to have similar experiences. No harm done, it took a tester from every major carrier to reach my conclusion.
[Samsung Galaxy S8 Guides, News, & Discussion] Silenus21:

[Samsung Galaxy S8 Guides, News, & Discussion] Bladescarr:
Sorry to ask another question to you Denson, but after seeing this other post, I was wondering;

(I have US Cellular)

Should I get the XAA/XAA/USC Firmware or the XAA/USC/USC.

From what I am understanding, they are both bloat free (XAA) versions. So what exactly is the difference, and which one should I be flashing onto my phone?

Thank you so much, and sorry to bother you again..
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
XAA/XAA/USC should be your firmware. It will be carrier data free and have every LTE band enabled.
[Samsung Galaxy S8 Guides, News, & Discussion] Bladescarr:
So use these directions to get XAA/XAA/USC or the other directions to get XAA/USC/USC?

---------- Post added at 06:34 PM ---------- Previous post was at 06:33 PM ----------

Alright, thanks for the reply.
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
Flash the SM-G950W XAC firmware with a modified version of ODIN then flash the origianl firmware for your phone back to it. You will then be on the XAA/XAA/USC.
[Samsung Galaxy S8 Guides, News, & Discussion] denson9874:
Just like [MENTION=7277512]mweinbach[/MENTION] stated, XAA/XAA/USC should be your result. Still trying to figure out how others were getting XAA/VZW/VZW with this method. Ideally with this method, everyone should have all bands accessible.

What my question is, does someone who followed this flashing method NOT have *#2263# code access in dialer?
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
I don't have access to *#2263#
[Samsung Galaxy S8 Guides, News, & Discussion] `SBR`:
flashing XAA on Tmobile/ATT will remove the Wifi calling functionality? are they able to access it..

XAA being generic unbranded, it is enforce to skip the carrier banded app.. so thinking anyone flashed has this funtionlity working.
[Samsung Galaxy S8 Guides, News, & Discussion] tassadar898:
Hey quick question I've read through about 40 pages and not sure if I can tell if this is possible. I got an ATT S8+ unlocked. I am using it with tmobile but I want wifi called and VoLTE. Is there a way to flash the device to make it T-Mobile and get wifi calling and VoLTE? I tried to flash the tmobile on regular odin but it just reverts back to ATT.
[Samsung Galaxy S8 Guides, News, & Discussion] denson9874:
So it seems that VZW disabling *#2263# comes from CSC being flashed via Multi-CSC. In orderto comfirm my assumption, can you do me a favor, if it's not too much to ask, but flash XAC, then try the code. If you don't feel like it, I'll understand. I would test myself, but I have a TMB sim.
[Samsung Galaxy S8 Guides, News, & Discussion] `SBR`:
the dialer control should be controlled by the CSC, i think..

i have G950F, and in DBT CSC where i don't have the control code option. but when i flashed TMB, its working with *#2263#
[Samsung Galaxy S8 Guides, News, & Discussion] denson9874:
Flashing G950U firmware autodetects your device and will continue to flash AT&T CSC to your device. We have yet to find a way around this, but in due time, we will figure it out. Sorry.

---------- Post added at 10:27 PM ---------- Previous post was at 10:22 PM ----------

XAA is a byproduct of flashing XAC and Mult-CSC firmware. Until the US unlocked firmware is released, there isn't a stand-alone XAA firmware. Flashing XAC and remaining on it will indeed remove Wi-Fi calling, but if you flash the Mult-CSC firmware over XAC, Wi-Fi calling will return, just as long as your carrier supports it.

---------- Post added at 10:29 PM ---------- Previous post was at 10:27 PM ----------

You were able to flash TMB CSC onto a G950F? Even though it's intended for G950U?
[Samsung Galaxy S8 Guides, News, & Discussion] `SBR`:
I used TWRP to flash CSC files.. International has CSC is in IMG format and while tmobile CSC is in zip format (within CSC.tar.md5 files).. so don't think we can flash the files directly in Odin.

can you share the link to the XAC firmware files?

maybe this why it auto detects..

EFS (partition) > Imei > mps_code.data >> the file has CSC code hard coded.. if you change the file only you can use the benefit of the CSC.

eg.

i have used the CSC selection TWRP files to flash TMB CSC.. i got wifi calling/VoLTE works (though the mps_code.dat points to DBT), if change the files to TMB only i got the Tmobile Boot logo, ringtones and dialer codes working..

maybe this will help in you identifying the workaround
[Samsung Galaxy S8 Guides, News, & Discussion] bestlands:
What about if I have the ATT S8+ and flashed the XAC version, I gained bands but I lost Volte and wifi calling, now you may be thinking I need them for att, but no Im switching to t mobile in a few weeks, anything I can flash to gain back the t mobile wifi calling/hd voice?
[Samsung Galaxy S8 Guides, News, & Discussion] Bl00dRunzC0ld:
I don't have *#2263# access either. I went VZW to XAC, then flashed TMB, to end up at XAA/XAA/VZW. I'm using the phone on T-Mobile with no issues. I don't have wifi calling though as far as I can tell. There's no settings and nothing pops when I use wifi. Not a big deal though.

---------- Post added at 11:21 PM ---------- Previous post was at 11:16 PM ----------

Based on the results of members who do not have access to the code, we can narrow this down to VZW not having access. So with that being said, the only way to workaround this is to somehow edit the CSC file within the Odin firmware to bypass the auto-detect code written. The only thing is that there isn't any proprietary firmware for each US carrier like previous Samsung devices. This may cause another problem unless we are able to obtain CSC file for each carrier.
[Samsung Galaxy S8 Guides, News, & Discussion] bestlands:
Can you explain how to do that and where to find the link for the s8+, im on the att version of the s8+, flashed the XAC firmware, now want to enable wifi calling/hd voice when i enter my t mobile sim. What firmware should I flash from updato and is it everything AP,CSC,BL, and where do i find the userdata, and do i need it?

---------- Post added at 04:32 AM ---------- Previous post was at 04:27 AM ----------

So just wondering are you saying that if I decide to do a Multi-CSC firmware onto my att s8+ and I flash the t mobile s8+ firmware only the CSC, then I will still get only the att bands and features of an att device not a t mobile one.

---------- Post added at 04:41 AM ---------- Previous post was at 04:32 AM ----------

Ive been following for this thread for a while, so basically there is no way to gain t mobile wifi calling/hd voice features on an att s8+ even after flashing XAC full. Your saying it will revert me back to att bands/att wifi calling/att hd voice even after flashing t mobile firmware? Or whatever the original carrier it was on? And if this occurs where we do Multi-CSC, do the updates also come from the original carrier? Lastly, where do the updates come from on the full 100% XAC firmware?
[Samsung Galaxy S8 Guides, News, & Discussion] denson9874:
That is correct. Your device being AT&T may outweigh the TMB CSC when you flash the Mult-CSC firmware over it. After reviewing the thread, it seems to be evident that the device IMEI may be read during Flashing. Crazy, I know, but that the only indicator that I can find that tracks our phones back its original carrier while in Download Mode. This is just a thesis, not 100 percent confirmed. Just the most logical inference that I've seen.

Think about it. US would have certain IMEIs that the Mult-CSC reads that associate the appropriate CSC to it. Canada wouldn't have these IMEIs in their CSC so it just flashes the CSC file that is associated to the Product Code embedded. That is why XAC doesn't install carrier apps, because it wasn't included in the unbranded firmware, and that explains why there are several difference Product Codes in CAN and UK.
[Samsung Galaxy S8 Guides, News, & Discussion] bestlands:
Will this method not work in order to get the att s8+ to have wifi calling and volte

"Try out this funny method you'll get Video Calling and voLTE but no WI-FI calling. I flashed full XAC, then TMO CSC and it gave me an error message, lastly I flashed back XAC AP and CSC and the 2 were unlocked. Didn't keep it because I prefer WI-FI calling than Video Calling. T-MOBILE firmware (user data not csc) gives you the 2 without Video calling.

Play around with PrinceOdin and the new Odin 3.12.7, when it fails on one it works on the other."

"So where I am now is on 955U with carrier code XAA. It looks like Wi-Fi calling is active (well, definitely active). Flashed 955U TMO (AP + BL + CP + Home CSC).

I used to see an "HD Voice" icon whilst calling on my note 5, but this seems to have VoLTE on. XAA is likely the USA unlocked code, anyway, so I'm fine with that.

Video calling...I don't really need. I have Duo and I have an iPad should I want to look at people. "

So anyone tried this and wanna confirm to me that I will be moved back to att CSC if I flash the t mobile one?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
you cannot edit the csc files since it will break signature due to the locked BL..

i did however think it was stated if you enable all bands on xac then back to vzw then everything works without the bloat.

i however got a new s8+ before that was figured out n dont want to mess with my new one lol

---------- Post added at 06:39 AM ---------- Previous post was at 06:38 AM ----------

one thing to add almost every time i reboot my phone going into recovery it checks the csc and i can see it deleting non vzw csc.. i just dont have another camera to take a pic of it lol
[Samsung Galaxy S8 Guides, News, & Discussion] bestlands:
So basically there is no way to make a att S8+ have t mobile features/carrier features at all?

Ok, I have one question. Where has everyone been getting the Multi-CSC firmware. I have not been able to find it.
[Samsung Galaxy S8 Guides, News, & Discussion] `SBR`:
there is a file called enforceskippackage which will have list of common application which not applicable to current branded, so every time it booted, it will wipe the application in the ROM. eg. VZW firmware have the TMobile VVM, Twfc, ATT xxx., SPRxx. files listed in the files so that it will not conflict the firmware.

S8+ Tmobile stock firmware (posted in Tmobile S8+ forum) has all the files in it for other operators, only think is when flashing it checks the CSC code and flash the relevant files.

the CSC code is hard coded in EFS > IMEI > mps_code.dat file, if you overwrite (not sure on unroot phone) you can flash any CSC codes of different region.
