It does. Download the firmwares from updato. The steps for it are the same as the ones I posted for the S8 (I did them on the + originally)

Thank you, just want the one that updates the fastest and i kinda like having no bloat so i might as well just stay here
[Samsung Galaxy S8 Guides, News, & Discussion] TimelessPWN:
Just to inform all those that have participated in this thread/those that are following this thread, I am still fully committed to the project of rooting the device/carrier switching, just started a new job recently and have been occupied with that. I am up to date on the thread and I am still researching and experimenting with possibilities to achieve our goal. I will update with anything new as well as try to be more active within the thread again!

So has anyone flashed the older XAA firmware that jerrygenius posted to google drive?? I understand everyone is trying to flash Canadian XAC, I'm just wondering about the 950U all XAA that was posted. I almost have it downloaded. Just curious. Thanks
[Samsung Galaxy S8 Guides, News, & Discussion] unitz0mbie:
I am curious too but in my opinion unless you're on Verizon you should use the Canadian xac to avoid the bloat, I just hope it updates fast since it's coming from Samsung and not any carrier
[Samsung Galaxy S8 Guides, News, & Discussion] sd_N:
Well after completing download it started back over like I had never downloaded it. Hey jerrygenius...is the file u uploaded complete??
[Samsung Galaxy S8 Guides, News, & Discussion] sniper7kills:
I downloaded it but had the same issue. Had to use Google drive on my phone and Mark it as available offline but I have a plus so I can't test.
[Samsung Galaxy S8 Guides, News, & Discussion] jerrygenius:
it is complete file. I will try to download by myself now to test it.

Can someone please post the link to the factory binary file for S8+, or at least tell me which page its on in this thread. I have read 30 plus pages and may have missed it or something lol. :confused: Unless I completely read this forum wrong and I'm way off track and if thats so I declare myself an idiot :mad: lol.

Hi Craya!

For some reasons, after I flash the Xac firmware without the HOME CSC, reboot and try to dial *#2263# but it wont let me do anything. it says something wrong with the code (with the sim card in) or No registered Network (without the sim card).

And then, when I flash the Verizon firmware, I have the same old phone before, vzn/vzn/vzn.

Did I do something wrong then?
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
You missed some steps. Go back to the post with my list of steps. I'd link it but I'm on mobile.

The gist is I did non home, setup, flash home csc, then dialer codes
[Samsung Galaxy S8 Guides, News, & Discussion] jerrygenius:
When u try this rom, plz try to type *#2263# in dialer. I would like to know if you can get into the service mode and check all bands avaliable.
[Samsung Galaxy S8 Guides, News, & Discussion] sd_N:
got it

I got it downloaded. Soon as I get off work I will be trying an install. I'll let you know the results

[Samsung Galaxy S8 Guides, News, & Discussion] craya:
I'm the one that wrote up the steps earlier for VZW -> XAC -> VZW. I was able to get the firmware to XAA/VZW/VZW and have no issue. The only thing I'm missing out on is WiFi calling. HD Voice is enabled, but I'm unable to select HD Voice AND Video option.
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
I just followed the instructions on post 653 by Craya. Verizon works fine with that.
[Samsung Galaxy S8 Guides, News, & Discussion] happy2472:
wifi calling isnt THAT important or HD video as my GF has the nexus 6 and cant HD anything ... post 653 here i come to atleast read the directions first
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
If you do go through with it, I used the odin version from this post: https://xdaforums.com/showpost.php?p=72195177&postcount=669

Also, if you do it into the XAA/VZW/VZW state, any factory resetting will turn in back into VZW/VZW/VZW.
[Samsung Galaxy S8 Guides, News, & Discussion] happy2472:
ok steps say it was a new phone and not setup ... does it matter my phone is setup and running now to odin these files?
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
Yeah, when I first did this on my S8+, I had already set it up and had been using it for a week. The initial flashing of the W firmware will erase your device. You can make a backup with smart switch and restore it, probably after the last step (which I'm doing at the moment)
[Samsung Galaxy S8 Guides, News, & Discussion] happy2472:
off topic of this recent chat ... dont know if this helps and i added this to the bounty thread ... the wug tool for the nexus 6 wanted to root my phone when i had it attached to my pc when i was re rooting my gf's nexus 6 .. something about detected an adb device ... dont know if this helps even with the recent eng file talk
[Samsung Galaxy S8 Guides, News, & Discussion] force70:
Was this before or after one of the guys had to return his device and get a new one because of issues flashing this and trying to go back ?

[Samsung Galaxy S8 Guides, News, & Discussion] YourDrinkingHero:
Interestingly enough, I have a VZW device and followed the steps exactly up until step 7, and instead used T-Mobile firmware for step 7 in hopes to switch it to a TMB device. However, when it came back up, it was XAA/VZW/VZW. How is that even possible?
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
You probably need to flash the TMO user data partition. I'm not too sure though

---------- Post added at 06:16 PM ---------- Previous post was at 06:07 PM ----------

I posted my steps after the guy returned his device.
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
I would add a tiny bit to the instructions you had, since flashing the W firmware will wipe the device (which I knew) I didn't know why you were setting the passcode and boot passcode. I thought it was necessary. The clarification is that you are not going to wipe it when the US firmware flashes, so what you set and do there after initial W firmware wipe will be on the phone later since you won't factory wipe it ( and return to VZW/VZW/VZW. ) I hope that when we get a true XAA firmware we will be fully unlocked even after a wipe.
[Samsung Galaxy S8 Guides, News, & Discussion] YourDrinkingHero:
Just tried this:

I went from XAC firmware, flashed TMB package (BL, AP, CP, CSC_OYN, Userdata in UMS), and now it's XAA/XAA/VZW. Also says Carrier: VZW on the bootloader screen. It's retaining the VZW somehow despite flashing to XAC then to TMB.
[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
Craya posted his steps after I returned my device. In retrospect, I could've recovered back to VZW and get to XAA/VZW/VZW. Follow Craya's steps and you should be fine.
[Samsung Galaxy S8 Guides, News, & Discussion] jerrygenius:
This is all bands Canada unlocked supports

And here is something new that I tried the old XAA this afternoon. It disabled the ability in XAC to get in *#2263# so anyone flash it w/ Verizon sim (which I won't recommend but if u want to sacrifice and try) plz tell me if it supports CDMA band
[Samsung Galaxy S8 Guides, News, & Discussion] sd_N:
This is all the band's supported by a factory mobile phone

Hi Craya!

I got it finally with XAA/VRW/VRW.

However, when I do the factory reset, it came back with all bloatwares and VRW/VRW/VRW again.

IS that normal?
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
Yeah don't factory reset at the end.
[Samsung Galaxy S8 Guides, News, & Discussion] T33H00:
Hi all!

Just wonder if I download Sprint firmware and flash it on my Verizon phone (directly flash, no XAC Firmware or anything), am I still able to use it on Verizon network, everything working including message and call?

All I need is the samsung cloud, i can live with the bloatwares.
[Samsung Galaxy S8 Guides, News, & Discussion] denson9874:
Hello T33H00,

Just to let you know, but all carriers are on the same build number. So, flashing any US branded firmware wouldn't do much other than loading up Sprint Carrier bloatware.

[Samsung Galaxy S8 Guides, News, & Discussion] sniper7kills:

Tried it....doesnt work, I believe Elliwigy posted about it...it's an automated script that runs devices thru. It'll make a supersu for any device, whether it locked or unlocked. But, it has to be unlocked for it to work for us.
[Samsung Galaxy S8 Guides, News, & Discussion] highaltitude:
Yeah I figured. Guess I didn't know they autogenerated the list etc. Figured if it was listed then it might work. We'll glad there is some hope though for root anyway!

[Samsung Galaxy S8 Guides, News, & Discussion] ashyx:
I have fully extracted the USERDATA partition and there is nothing related to carrier data or boot animation. TBH I didn't think this would be the case as that stuff is usually located in the CSC image.

The USERDATA image contains nothing more than carrier bloat apps, dalvik cache odex files and a couple of text files containing the list of apps installed.

Everything carrier and radio related is in the HOME_CSC_OYN cache.img.ext4 image. I have uploaded the sec_omc.zip contained in the cache.img.ex4 image. This is what gets flashed when the device reboots to recovery after ODIN finishes flashing.

You can find carrier related settings in \system\omc. This folder gets placed in the system folder on the device.

As far as I can see, any issues with incorrect/missing functions are due to an incorrect CSC.

[Samsung Galaxy S8 Guides, News, & Discussion] Ihmaiw2d:
Guys are can almost guarantee this will get rooted eventually. Some of these post are just down right discouraging. The device is just to new, but there's no reason to think it's hopeless because it will get a root eventually, lol.

The Galaxy S8 has some pretty big differences​ from past S series devices, but that's the fun part and it sets what the future of rooting will look like. They changed stuff around, and honestly that could even be a good thing once we get the right development on the S8. As the first devices to change things around are usually the weakest once you know what you're looking at. I mean it could take for what feels like forever but eventually rooting this device will be easy compared to what's to come.

I probably should have went HTC because of the easy to unlock bootloader and how much I love Roms, but It's to late now. I do have full faith this will get rooted though. Maybe not a bootloader unlock but something. I'm not working on this project but I have a good feeling, and definitely don't think it's unrootable/not lock being unreachable.

How did you manage to flash a custom kernel?
[Samsung Galaxy S8 Guides, News, & Discussion] suzook:
Wow, very interesting.
[Samsung Galaxy S8 Guides, News, & Discussion] jerrygenius:
Very Interesting fact. But Is the CSC file actually contains all information for the all variants in US?

Kind of interested how odin determines the variant of our phone.

---------- Post added at 09:12 PM ---------- Previous post was at 09:07 PM ----------

Another thing I found in the XAC version is that, the CSC is flashed to /system/csc. In this folder all of the CSC folders exist but only the correct one (XAC) has the cscfeature.xml and all of those stuffs. Other CSC only hava a txt file init called "enforceskippingpackages.txt"

I am suspecting that we might be able to find a way to let the odin recognize our phone to different carrier variant
[Samsung Galaxy S8 Guides, News, & Discussion] ashyx:
Well this is VZW specific firmware. So the CSC sets it up for the carrier variant. However as far as I know the EFS partiton also contains carrier/device specific data such as sales code, CSC etc. The CSC is probably set using the data stored there. However I'm only speculating.

Unfortunatley without root nothing can be changed in the EFS folder.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
well you misinterpreted my post completely lol.. i wasnt at all saying it wont happen or its impossible i was specifically referring to the factory binary/combination firmware.. so not discouraging just letting them know we spent hours upon hours on the combination firmware and so far as others previously stated is useless for root

---------- Post added at 09:32 PM ---------- Previous post was at 09:29 PM ----------

we didnt.. the kernel in factory binary is permissive and signed by samsung (not custom)

you have to inject into stoxk AP.tar and flash in odin as that partition contains a meta data folder or else it wont boot.. but even the permissive kernel on stoxk had some issues but still didnt allow any form of root
[Samsung Galaxy S8 Guides, News, & Discussion] Ihmaiw2d:
I wasn't just referring to you, more of the whole threads negitivity on the whole thing in general, unfortunately you were the first post I seen on the negitivite side so my bad it isn't aimed at you, just the people getting down and thinking it's not going to happen already.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
lol not sure how its negative in any way as i am not implying it is impossinle or wont hapoen just that as it stands the binary firmware some spent hours on didnt provide anything groundbreaking..

fact of the matter is, myself and others will be on xda every day as typically root just happens out of no where lol
[Samsung Galaxy S8 Guides, News, & Discussion] V0idst4r:
Interesting
[Samsung Galaxy S8 Guides, News, & Discussion] Ihmaiw2d:
Yeah, I got you. I pretty much just quoted by you on a dime and I probably should have quoted another user but this thread has alot of what seems like uncertainty, things will come out, we're are using Samsungs afterall. Root is hard, just want people to keep this thread encouraged and give a reminder that it isn't impossible and will happen eventually.

Apple might be a total different OS and development, but just look at the progress of Jailbreaking, it always seems 100% impossible when a new device/OS comes out but it always gets done, just have to find the right exploits lol, no security is 100% secure lol.
