Hi PoseidonKing,

this help thread is now a sticky thread.

So be prepared to receive more questions here ;)

I have subscribed to this thread and will help to answer some questions.
[Samsung Galaxy S8 Questions and Answers] It_ler:
Many questions, I am just trying to answer some:

As it is possible to flash the firmware for the single SIM variant to a dual SIM model, it should work for your device too.

But you will definitely lose the dual SIM functionality. You will have to download the firmware you want to flash and flash it manually (using ODIN) to your phone.

And you will no longer be able to receive official OTA updates from Samsung (or your provider).

At least as long as the installed firmware does not match your exact device variant.

KNOX should still work, if you stick to official Samsung firmware.

Although it works for other generations of the Samsung Galaxy S series, there is still a chance to brick your device. So create a backup before and be cautious when flashing something to your phone.

I am sure that there is a guide how to flash a firmware with ODIN. If I will find it in the next few minutes, I will add a link here:

[GUIDE]: How to flash CRB7 using Odin - S8

OFFICIAL STOCK Firmware-update (Odin) thread Samsung GALAXY S8 SM-G950F

To receive official OTA updates, you will have to flash back the official firmware for your device first.

What Android 10 Rom has everything working (all the sensors etc.) ? And stable?

What's your Android 10 rom of choice?
[Samsung Galaxy S8 Questions and Answers] klaus1221:
Stable - none of them ( you get fc on every single one )

Sensors - beside iris "scanner" and "health" sensor , "work" all .

VoLTE will not work ever .

Camera work only when she wants .

Fast charging will not work as well , on some rooms the "developers" say it work's but is just some text/animation on the lock screen .

And almost all of them are EOL .

I try two off them ( Bliss (EOL now) and Pixel Experience Plus ( which is EOL but the thread is still open ) , there is no point to try all of them , they are the same room with other name and the same bugs .
[Samsung Galaxy S8 Questions and Answers] Kharabsheh:
Alright, thanks so much for the help ?

Will stay at stock, and find some way to get Android 10 navigation and notification.

Hello! I'm planning to root my S8 (G950N) which is on Pie, but i don't want to lose access to my Knox Apps (secure folder, health, pay, etc), is there any way to bypass this after rooting? I've read a few tutorials here but i'm unsure if they actually work so...
[Samsung Galaxy S8 Questions and Answers] m4v3r0ne:
Hello there.

I'm not really a noob but I do have a total noob question:

If I flash my S8 with a custom ROM will I lose KNOX feautures?

As I understand KNOX is only tripped with custom Kernels (does that automatically apply to any "UNOFFICIAL lineage version?)

I know my way around flashing, custom roms etc. but this phone was _actually_ paid for by my brother (I usually only drive handdown devices) and I immediately got used to the fingerprint sensor - that I thought I'd never use - for unlocking the screen.

I already ran custom Android 11 and 10 on much older devices so the S8 is perfect for it I think.

Just never have been in a dilemma like this before, potentially losing newly-beloved feautures.

Please help.^^
[Samsung Galaxy S8 Questions and Answers] It_ler:
After flashing a custom ROM, KNOX will be tripped.

If the custom ROM supports the fingerprint sensor, this unlock method will still work.

But some apps (e.g. for banking, etc.) will no longer work on a device with tripped KNOX.

So my advice is to ask in the custom ROM thread, if it has all features you need/want on your mobile. If yes, feel free to flash it.

Good luck!

BTW, it is always a good idea to backup all imprtant data before flashing ... just in case ;)

[Samsung Galaxy S8 Questions and Answers] nintendowii111:
I have a galaxy s8 that has data on it that is important. It's asking for a pin with 4 or more digits. I have no idea what the google password for it is ( so cant use google to recover). Probably doesn't have USB debugging enabled. I have no idea what version of Android is on it. Is all hope lost or is there anything that can retrieve the data? Primarily SMS/text messages is what is needed. Assuming android 7 ( the original version when it was shipped) is still on it; could that allow for some exploit? Thanks for any help.
[Samsung Galaxy S8 Questions and Answers] callumbr1:
You will most likely lose access to most of your knox apps so root at your own risk! You can get health working by running the command ro.config.tima=0 in terminal.

Some custom kernels claim to be able to have secure folder working and samsung pay. However when using my s8 it never worked.

Magisk hide works so that you can use Google pay/banking apps.

I suppose its down to whether you want to root enough and use knox apps, or keep stock and use knox apps.

Hi! So i bought S8 with cracked screen, replaced it, made factory reset and now i can't add new fingerprints. I get to the point where it says how to scan finger and scanner is not working. When i dial *#0*# and check sensor info everything is ok with all test passing. I also tried another sensor - same thing. Is my logic board broken?

[Samsung Galaxy S8 Questions and Answers] sambelee:
Hello, I'm really in need of help.

Recently I flashed stock via ODIN ( G950FXXSBDUA3_G950FOXMBDTJ1_SIN ) formerly was using a custom ROM.

My S8 has 64gb of storage but after flashing stock my storage is capped to 16gb, I have tried using date n time then factory reset method but never succeed.

I tried flashing multiple times but still to no avail. Now I tried flashing to Hades Q rom, but my internal storage still stayed the same.

How can i fix this? Thanks
[Samsung Galaxy S8 Questions and Answers] It_ler:
Maybe flashing the custom rom has changed partition sizes. Then you might have to re-partition the internal storage with the stock pit file again, before flashing a stock firmware.

Re-partitioning will wipe all your data on the internal storage. So I hope that you already have created a backup of everything important.
[Samsung Galaxy S8 Questions and Answers] sambelee:
Thank you for your reply, do you have a link to a guide that I can follow? I'm quite familiar with flashing custom roms but haven't tried what you've said

Despite this, I've encountered another problem when I installed TWRP via odin, everytime I tried to install the first problem comes back and I have to install PIT all over again. Do you have any suggestions? Right now I want to install TWRP then flash a custom rom.
[Samsung Galaxy S8 Questions and Answers] It_ler:
As I am on stock Android ATM, I cannot help much.

But I recommend to flash TWRP recovery like described here:

https://xdaforums.com/t/recovery-official-3-3-1-x-twrp-for-galaxy-s8-and-s8-exynos.3847712/

And then install the custom rom you want via TWRP.

Yes those steps are exactly what I did and it always fails. Oh well, I kind of intend to use stock anyway, I'll try again next time.

There is a toggle at the top dropdown statusbar - see my screenshot (it's from my S10 as I do not have my S8 here ATM).

But AFAIR Samsung introduced this feature in more recent firmware versions. Maybe you have to update to the latest available stock firmware to get it.

Hi! Might be a noob question. I have the SM-G850FD, have followed the guide from the TWRP thread and am (I think) having a problem: When I go to install no-verity-opt-encrypt-x.x.zip, I get the following error from TWRP:

Updater process ended with ERROR: 1
Error installing zip file '/sdcard/no-verity-opt-encrypt-6.1.zip'

When I first saw this, I tried rebooting into TWRP and enabling modification mode (not read-only mode) and tried re-installing. Failed. Tried re-wiping/formatting. Failed.

While I haven't tried rebooting out of recovery, I'm afraid that I may have bricked my phone.

Here's the full log:

Spoiler content hidden.

Edit: The phone bootloops but shows no errors when booting normally but is able to make it back into TWRP using ODIN.

I just purchased the phone used and it seemed like it hadn't recieved updates in some time, I updated it once, but did not try to do any more updates. is there a chance that it wasn't updated to have the AQG bootloader?

Final Edit: In my case, it looks like either the no-verity install worked despite reporting failure, or wasn't needed: I'm now running LineageOS

I've read that Pegasus Exploit works by rooting a victims smartphone and copying all the data.

The problem is, people here on XDA couldn't root the Galaxy S8's Android 9 for over 2 years already.

Do you think Pegasus exploit can just easily bypass Samsung's tough security, dual bootloaders, Knox in Galaxy S8 Qualcomm and simply root it?

I got a Galaxy S8 G950F with Android 9 ( G950FXXUCDUD1 ).

Can i simply Root this device by Flashing TWRP via Odin ?? ( OEM Bootload unlocked surely :p ) or will i get problems with this android version ??
[Samsung Galaxy S8 Questions and Answers] Staidey:
Yes you can, for some reason Samsung made European G950F and Chinese G9500 unlockable and downgradable, can be rooted, custom romed and etc. unlike North American models that utilize dual bootloaders, tough Knox to prevent rooting, TWRP and custom roming.
[Samsung Galaxy S8 Questions and Answers] Broken_Mess:
So it's been a year, or 2 I can't remember since I last used this phone. But I bought this phone through Boost, used it on Boost without issues and then switched to another carrier with a new phone and number. Well 2 days ago I reactivated the S8 back on Boost. I received my SIM card booted up the phone and have 2 notifications. "Invalid SIM" and "Please contact Sprint to unlock device." I've spent a total of 2 hours on chat with Boost between 2 days troubleshooting and trying to figure it out.

Other thing I noticed, I do NOT have Mobile Network Settings in my phone. I even tried to search for it with no luck, I was going to check the APN but that also is no where to be found.

So I hopped onto a Samsung discord where someone advised that I re-flash the stock, which led me to this site to download Odin and Frija. Which I did, and after countless hours of trying to figure out why I kept getting a fail, I switched computers and successfully completed the flash. Cool. Phone boots up, but now it's stuck at 32% update. Get out of that, wipe the cache, reset the phone, it loads up.. Yay, NOT. Still no Mobile Network Settings, but I can search the APN, there is no APN and the "ADD" is grayed out. I'm still getting the same notifications "Invalid SIM" and "Please Contact Sprint to unlock device."

I'm not sure what else I can do, or if there's anything else I can do? I don't understand why it's telling me to contact Sprint to unlock, when It's a Boost Mobile Phone, with Boost apps, and Boost load up screen, purchased from Boost.

[Samsung Galaxy S8 Questions and Answers] heyjh:
Hello, very new to this forum and to issues with my Galaxy S8. I want to know if it'll be safe for my build number to flash from Pie to Oreo/Nougat. I'll try my best to get the vocab right.

Backstory: I'm in a different country so I use an iPhone for calls/messages but I keep my old S8 for the UI design and old apps/take photos. I hadn't updated it for years (the software it was running as of 2 days ago was Nougat) but then I stupidly allowed updates and it went up to Pie.

I do not like Pie at all. The UI is ugly, the alarm's voice changed, some apps look funky, etc. I've spent the last 12 hours intermittently backing up my photos/files and Googling ways to flash to Nougat. It looked promising until I saw some things about build numbers and bootloaders and now I'm 95% sure I'm gonna end up bricking my phone.

Spoiler content hidden.

From what I've googled, it looks like my phone has a bootloader binary of 8, and most of the firmware downloads for G950U stops at 5 or 6.

I'd like some help in deciding whether it's worth it to try and do everything (root, Odin, TWRP, whichever) or give up and just not look at my S8 too much.

And if there's anyone who knows how to do this and is willing to help me step-by-step, I can offer some kind of monetary compensation. I didn't see anything in the rules against offering payment for services but if it's not allowed then I can draw/make something for you instead (if that's okay).

Thank you for reading this great wall of text, hope you have a stress-free day.

Nice tool indeed, I downloaded the firmware recommended by the tool and flashed it, however, after multiple reboots, it brings me automatically to the recovery, where the attached errors/ logs are shown...

I already flashed this firmware version before, so this result was to be expected. However, I noticed now, that verification of the firmware fails, because the folder with the info what the right firmware would be isn't found?

I can't garantee that the device works even with the right firmware, the seller said it one day just started bootlooping, and that's how I got the device.

SM-G950W, latest software updates

-I changed my password for no good reason and already forgot it. Now locked out with some very important family data on there (6 weeks of photos of my newborn + voice recordings of my grandfather who recently passed). I care about that data 1000x more than the phone.

-Biotmetrics work fine, so I can use SamsungPay from the homescreen

-I can also log into findmymobile, but looks like I was paranoid and disabled the remote unlock

-I had onedrive backing up my photos up until 6 weeks ago (haven't found a remote way to get that restarted)

-I've tried some of the ADB options suggest by google, but looks like I also disable debugging (device detected but unauthorized), BUT it does seem like it can sideload.

Where do I go next? I'm guessing if I can get a recovery with filemanager on there (like TWRP) or just a file manager (aroma), I can use the trick of deleting the lock screen password OR just find the photos and then reset the device? But I don't know if it's possible with a Canadian snapdragon variant? Any direction would be appreciated!!
