You are having connectivity issues with Odin and your device. You will need to sort those out before you can flash anything: this rom or stock.

I don't really know windows anymore yes been too many years since I've really used it at all, but some things to try I'm aware of:

1) check Samsung drivers are installed

2) use different USB ports and cables. Be sure to not use us3. 0

3) get a USB 2 hub and run your s8 through that.

Beyond this, this topic has been covered extensively in this thread. Read through it and follow the suggestions there until something works
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] warriorkalia:
Okay, I wasn't sure that it was a connectivity issue. I swapped out the cable and after a few tries it worked. Thank you so much.

Hmmmm... I wonder how well the story would go over, if I took the phone to the Verizon store and said that it bricked during the update.... Wonder if they'd give me a new one that's still on U1

Update on all this, it's an official bricking. Guess it's off to the Verizon store I go tomorrow. There goes half a day spent. :(

following the directions on the thread listed, i have had 3 consecutive bootloops trying to flash sdk 24. 88.2 arm64- is there something i may be doing wrong/out of order?

(sorry if this is too off topic for the thread, happy to delete or remove as needed)

EDIT: SUCCESS

Thx for the help! Not sure if i neglected mounting system read write or if i got impatient waiting for reboot. Either way im in business now!
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Goddly:
Shouldn't. Re download? Xposed installer installed.

Flash with flash fire. Mounting system read write...

Allow a few minutes to boot.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] 10.west:
thank you. will try again in a few moments. much appreciated.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] Goddly:
Apparently all is well?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] 10.west:
absolutely. i edited my original comment as a response to your instruction. not sure how the notifications here work, but yes, install is good for the rom and gravitybox is working with all my usual modules. thanks so much!

Am i still under this ROM ? I'm on AT&T so if anyone has AT&T i can say it works and still fast. Just wondering what else changed. Text , call and etc been working.

You flash part 1 then once it goes into the download mode again, you flash part 2, then factory reset after that one.

Glad it worked ...okay, a thought...we're always trying to gain root access, usually through boot-loader but not always right?

This may be a repeat or already tried method, and apologies...

Kustom Live Wallpaper and widget enable you to access the ENTIRE file system...all the way to RIL in private-app...could an exploit ride on it's coat tails?

Once it's there, can it make use of being there? :confused::confused:
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
What bootloader version is your firmware? If it is v3 then until today you would not have been able to use this method. I just posted the v3 compatible bootloader file that you can flash during Part 2. Take a look at the description of Bootloader versions in the OP to figure out what version you have.

If its version 3, you are in luck, you can just download the new V3 BL Part2 and flash that in place of the one that is failing.

If its version 4, you the opposite of in luck as that firmware has patched the root method being used here, and as of now there is no known way to get root (although I am working on it).
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
BL V3 Support and Updated OP!

Thats right folks, All of you on V3 Bootloaders can rejoice in rootness again, as I have posted a V3 PCR BL part2 file to the Downloads section in the second post.

Just Follow the instructions as normal but use the new V3 BL in place of the original V2 one.

IF you are on V2, there is NO REASON to update to V3. In fact, only bad things can happen, no good things. By now the OTA train has long forgot about you (hopefully) and with rooted phones you can't apply otas anyway, so you are safe from the force-updating madness that is regular stock.

And for the record: My version has a verified working fingerprint sensor. I know there were issues with that before on V3.

Let me know if there are any issues!

The only thing I've seen so far is the calender icon not displaying right. But no biggie everything is perfect wifi,Bluetooth,smart lock. It all works and it's great lol. I haven't even seen the aod screen glitch but time will tell. Couple things im curious about, why don't you use brb1 as system? Second why do I only see the custom boot animation when powering off?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
This version predates brb1. I will likely put out a new version soon l

Anyone else getting the system update available notification?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
Are you running the latest version?

Regardless, flash the zip in Post #3 in this thread titled "Remove OTA apps, downloads and debug messages" in FlashFire (TWRP MIGHT work, but I havent tested it there) and this will go away. You really should be running the latest version if you arent though, I'm not creating additional new fixes for any old versions.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
Updated V3 BL Download

Hey Folks, a quick V3 BL Update:

I discovered (thanks to a user informing me on telegram) that there was a slight issue with the new V3 BL firmware that could cause you to get an error when trying to boot into recovery following a flash regarding "unable to mount cache" or something similar that will cause a bootloop. I have uploaded a fixed version and the new link is live on the first post, but if you downloaded it before now you will have the affected version. Its fine to use if you dont have any issues flashing it, but otherwise you should redownload it now.

Thanks, and sorry for the inconvenience!
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] netlagger:
Yup, I'm on the bql1 version. I updated finally it's been a while. Even did the flash twice to make sure I didn't miss anything. I'll download the remove file.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] koobie777:

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] de Valle:
Is there any possible reason that after rooting with this method, my S8+ fails into 'modem fail' mode 100% of the time I leave my home? It sounds insane, but while in my home the phone works perfectly well on both WiFi and mobile.

Every single time I leave home, it reboots into the modem fail error literally just after leaving my driveway. This is absolutely inexplicable (well actually it must be switching to another tower that causes a reboot and fail), but happens without fail nonetheless. Upon arriving home, I reboot from the modem error and the phone works completely normally.

Any ideas or explanations for such would be appreciated.

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] droseofc:
I flashed as stock CSC and CP file in odin and fixed this issue I was having on Sprint. You may be able to do in flashfire, not sure, but I definitely can say odin flashing CSC and CP fixed my modem crashes

---------- Post added at 04:55 PM ---------- Previous post was at 04:52 PM ----------

So, if I was on the version before the most recent BL you released, I should not flash the newest BL you uploaded? That confused me so, basically, I have whatever the latest version was before the new BL was uploaded (v3?) Everything works fine now and to clarify, the v3 new BL is only for those already on v3 but does not provide any benefits to those on v2?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
Do not flash the CSC it literally does nothing to help you but erase your custom boot animation and replace it with stock. You already have those xml files in /system/omc. Just the CP file, that will fix your issue based on what was said.

[MENTION=7172205]droseofc[/MENTION] which specific firmware did you flash cp from? I would love to bundle them in a new BL package for everyone else.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] droseofc:
Sorry about the CSC, though I can honestly say I havent had a custom boot since the first release of this. I clean flashed the 2nd version, multiple times, and every time have always had the sprint boot. As for CP, ive used more than one and have not had an issue with any. I think the current one is bql5 but not 100% sure. Is there a way to check on the phone?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] de Valle:
I concur with [MENTION=7172205]droseofc[/MENTION] that my boot animation is stock Boost, and always was both times after clean flashing with Odin (1st time with your custom ROM and 2nd time stock). I don't have a custom shutdown animation either, nor ever did, mine remaining stock Boost like the boot animation.

2 minutes out of the box, I tried SamPWND but no joy. Didn't work as advertised for my device. My savior was your custom ROM and SamFAIL which worked exactly as as stated, albeit lacking the custom boot and shutdown animations. Now running 2BQL1. You have my gratitude for helping me achieve root on my stubborn device.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] rafaelox24:
can you add any dual speaker mod? and this rom will be updated?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] MitchellRyann:
Ok so I have a pretty noob question here...

So since my phone is rooted now with Xposed installer on it..

I am not able to log into my snapchat, and I've searched for a way and I need to be able to get back to stock to sign in and then re root. Or something like that.

I want to be able to flash stock again so I can use android Oreo and just use snapchat again but I've tried it so many times and I always get a Fail(Auth) on Odin. Can anyone help me with a way to either get snapchat working or help me get back to stock firmware? Any help would be great! Thanks!

anyway to enable bluetooth tethering? that's what i was using before this rom to connect to the tablet in my car.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] stillriza:
Snapchat won't work with this rom because of Root. No fix for it as far as I know.

To go back to stock, Download your official carrier rom from sammobile.com, which ever version you want, extract it and you'll have the separate files you'll need (1 for each AP, BL, CSC, etc). Open up non-modified/regular Odin and select & load the seperate AP, BL, CSC, etc and flash. Sammobile.com can be slow at times but Partcyborg had posted another site to get your stock rom.. i think page 60 or so in this thread. You can search and check for that link. Either way instructions are the same.

edit: I was 100 pages off ;) it's page 160 :D go here https://updato.com/ to download.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] pimpdaddy00:
Snapchat does work, all you have to do is deactivate Xposed, then full unroot in Super Su, delete Snapchat, redownload it then log back in. Then flash SYSTEMMODE super su in safe strap then go to Xposed and reactivate it. This method always works for me.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] CynicalHeight00:
Let's say that S8+ doesn't get the Oreo combination files. Is there any chance for root with another method?

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
None of our devices boot with an engineering bootloader. That these exist out there for the s8 is a complete fiction. What you found was a combo / factory rom that someone renamed "eng boot" and probably sold it for more money

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] PlatinumMOTO:
I have tried to flash the CP file only from a stock version of Sprint and ATT - build: G955USQS2BRB1 problem is when my phone is originally sprint but it is unlocked and using ATT. I've flashed both the SPR version of just the CP file in Odin, and I've flashed the ATT version of CP each time I do it goes through PASS and then upon boot it states: System software not authorized by ATT has been found on your phone and doesn't boot. Now I can restore my backup thanks to safestrap but every time I leave my house the modem crashes with the current which I had to use: G955USQU2BQK5 but my baseband was updated to 3CRC7. What can I do, when I tried to root with BQL1 it says model dismatch in Prince.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] jdawgg21:
My build ends with CRD4. Does that mean I am on Bootloader V3?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] azeemguy:
I am confused. I had a Canadian variant of S8 Plus from Fido G955W.

Before flashing through this procedure my phone was network unlocked.

Now after flashing when I insert sim it says that I need the network unlock code? Why? I network locked it?

How do I go back to factory firmware the way it was before flashing?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] IJoxer:
The number right before CRD4 is the bootloader revision, it explains it in the OP.

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] RevolutionaryMan:
Hey guys so I finally came around to putting this on my Canadian s8+ and everything worked out. The only thing that I can't figure out is getting Samsung Game Launcher to show up. I've tried downloading it and moving it but nothing shows up. If anyone can help that would be much appreciated
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] koobie777:
Download the app for nougat from apkmirror then install like a normal app. After installed enable in settings. If you want you can install game tools too but the new version sucks with a stupid floating button instead of changing the navbar.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] RevolutionaryMan:
Keeps saying that the package conflicts with an existing package but i checked settings and cant find anything. GameHome.apk is in system/apps but i couldnt figure out how to get it to show on the phone
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] IceAzures:
I have a noob question as well. Page was updated with how to root if your on v3. I have part one and two, but not sure what to do with part 3. Can any of you guys help clarify? Sidenote, this rooting process is brand new due to me being on HTC for the longest time..

nevermind, did not look hard enough. Found it.

[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] azeemguy:
Any help please? I am not sure why the phone is network locked now. I was on base band 3 G955WVLU3BRD5 and followed the instructions.

Just got replacement phone with Oreo8.0.0 G955USQU3CRD4 can I still root and use this Rom??
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
Nothing in the directions here, in the firmware being flashed or in the root directions, has absolutely anything to do with sim locking on a device. If your device is sim locked after flashing this, it was sim locked before flashing this device.

Or, you did something else completely unrelated that I can not even begin to imagine, but unfortunately you wont find any help with that here
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] koobie777:
That means that game launcher is already installed. You can replace that apk in system/apps or put the app in system/priv-app or system/apps to update it. The setting you need to look for is to activate game launcher. Here's a screenshot.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] RevolutionaryMan:
For some reason I'm not able to move files between those folders even with root access. Going to try a fresh install and see what happens. Thanks!
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] azeemguy:
Hmmm. Appreciate the response. It is very odd to me as well.

So in order to switch back to stock...

1) I use regular ODIN

2) Use the one firmware file (G955WVLS3BRE1_G955WOYA3BRE1_FMC.zip) downloaded from SAMMOBILE.COM

3) Use ODIN, input relevant files in fields and flash.

Am I missing anything?

also, i found a way to fix netflix, you have to download a 3rd party apk

1. install netflix apk

2. download a root explorer

3. go to system, then lib (/system/lib)

4. create an empty file called liboemcrypto.so

5. make sure permissioms are rw-r-r 0644

6. reboot

7. profit
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
Wow great idea with the the empty liboemcrypto file! I will try this later tonight and provided it works as expected I can package it into a zip for everyone who wants to use it too.

Just to make sure I get the credit posted right for the thread, did you find this somewhere or did you discover it yourself?
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] CynicalHeight00:
What system applications can I delete without a problem? I have noticed if I delete a system application it has an adverse effect on my battery and/or in the adb logcat the cpu keeps making these stupid calls to these applications I have deleted.
[Samsung Galaxy S8+ ROMs, Kernels, Recoveries, & Ot] partcyborg:
None!

Basically, no apps can be removed without compromising either a critical system function or a device feature that was deemed important enough to keep it's app around for.

In short, if an apk didn't meet the criteria above it has already been removed.

If you read the OP you will see that I already did a very very deep debloating of the firmware in this rom, learning the puropse of each system apk by any means necessary, including decompiling the apk and reading the Java code to understand what it was for and to guess at how much battery it would take when not in use.

Basically, if it's removable without breaking stuff and/or eliminating a feature that I use or enough people complained about being gone, it's already been deleted.

For future reference though, stuff like that is almost always covered in the OP, which is something you should always read in it's entirety before flashing any rom or mod, and it is imperative that you read it before posting questions to the thread, as they may have already been asked and answered or their answer could have already been covered
