[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
It shouldn't cause an issue no. Try it first.

Just follow it exactly step by step. Wipe at step 3, make sure it's format and not just wipe. No need to wipe after that.

Let me know how it goes
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Install went fine, but when I boot and try and set up phone, after it checks for update it goes to a black screen and I can't do anything

Edit: Yep, remove sim and not connecting to wifi fixed it!

Gonna try and pull my sim and not turn on wifi and see if that fixes this issue
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
That's not twrp related that's ROM related. Try a wipe cache/dalvik from twrp
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Knew it wasnt twrp related, just removed sim and didn't connect to wifi when I went to set up, worked no problem!
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
Nice. And you can mount data now?
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Not sure yet, it showed internal storage though and not 0 mb

I cant add an account, so it sounds like I need to wipe like you suggested, how do I get to twrp without the app? (I cant log into google to download any apps or anything so I cant get the TWRP app)
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
You don't need the app. Power off, hold vol up, power and bixby. It will boot you to twrp. Wipe from there.

Try adding Google account manually in settings> accounts
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Thanks, I wasnt powering off first

well dont have the ability to wipe because it can't mount data, even tried the zip fix again and it still didn't work

Guess I need to do the whole process over and before I reboot wipe cache and dalvik at the end?

I tried adding manually, didn't work, so I have a phone, just no google services, when I try to add an account it gives me the screen as if it was checking for an update and then just a black screen
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Found the data mount fix, accidently found the note version. So I can mount data now, but wiping cache and dalvik didn't fix problems, so I guess tomorrow I'll flash stock from sammobile and then retry twrp now that I have right data mount fix unless someone else has a fix

Guess I could also just flash a custom rom right?
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
Just flash a custom ROM if you can get into recovery so you don't lose your TWRP by flashing a stock ROM...
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
Yeah, I would try a custom rom. I'm currently running renovate and it runs perfect. Before you wipe try updating all Google play apps. Do it manually with the apks
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Since im on 2CRED I have to flash a rom that is also 2CRED correct?

I've also seen one that is G950FXXU1CRED so I can't flash this rom correct?
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:

You can...

It just means you can't downgrade your bootloader anymore going forward and you are stuck on v2 bootloader (that's not a bad thing...a lot of us were flashing Oreo custom ROMs while still on Nougat BL...)

Any custom ROM with XXXCREX or latest release after that will definitely do just fine for future flashes...

Are either of you two able to help me with Odin? I tried flashing a rom, it said it installed correctly in the set up but then it sat for over 10 minutes on the black samsung galaxy s8 screen

So figuring it wasnt working I decided to try and flash stock rom, I downloaded it, followed the Odin guide, do I only need to flash the AP file?

This is Odin's log

<OSM> Check MD5.. Do not unplug the cable..

<ID:0/004> Firmware update start..

<ID:0/004> SingleDownload.

<ID:0/004> boot.img.lz4

And it just sits there, right now at 15-20 minutes, no indication that anything is being done on phone of within odin

Any help you can offer?

Thanks
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
If your flashing a custom rom then flash through the install bit in twrp. Not odin. Odin is for stock Rom only.

If your flashing an Oreo stock Rom you must use odin 3.13.1 otherwise it will fail. The odin your using is not compatible with newer Oreo firmwares

---------- Post added at 04:25 PM ---------- Previous post was at 04:23 PM ----------

Your odin is the wrong version. For newer stock Oreo firmware you must use odin 3.13.1. After flashing it will stay on the glowing Samsung logo for a short while it's normal. Flash all 4 parts. BL CP AP and CSC. USE CSC_HOME to keep data or CSC to wipe

If your flashing custom rom flash the zip through install in twrp

Edit: post failed that's why I posted 2 times lol
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
I flashed my custom rom through twrp

didnt realize there was a newer version of odin, didnt think to check so Im gonna try that
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
If your flashing custom ROM yeah flash through twrp. 1st boot can take about 10 minutes on the Samsung logo before it boots
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Yeah updated odin now seems to be working, I don't know why I didn't think to make sure I was on most updated, mostly because I have a 15 month old running around so its hard to sit down and think for 5 minutes!

Thanks, hopefully this works
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
Yip...either all Odin with stock or TWRP with custom ROMs...

And first boot does take a long while ~10 minutes...
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
I thought so but wasnt sure, it sat there for at least about 15 minutes and the thread didn't have anything about it, and it wasnt just the flashing samsung logo which its doing now as im reverting back to stock, it was galaxy powered by android screen, not one that I had seen much of even when I installed twrp, when I waited on twrp it was the just the word samsung that would pulse

---------- Post added at 11:47 AM ---------- Previous post was at 11:39 AM ----------

Yeah I know the first boot usually takes some time , but the fact that it said galaxy s8 powered by android instead of the samsung only screen had me feeling like the rom I installed wasnt gonna work
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
No problem. Let us know if you need anything else. Or thank the posts :svetius::)

Help please.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Thats the problem, that's the Canadian version and has snapdragon, there is no TWRP as far as I know for snapdragon versions (other than maybe the Hong Kong version)
[Samsung Galaxy S8 & S8+ Cross Device Development] muellerm30:
Is there a way I can get it back to stock? I realize that this question might be best asked on another thread. Just need some direction.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
I would go here

https://updato.com/

Find the most recent firmware for your phone and download it

Download the most recent odin

Start odin

Go into download mode (on phone)

Connect phone

Load all 4 files

Flash

This should do it, may need to check a more in depth odin guide

If you want you can try older firmwares, I dont know if you flash an earlier firmware (namely bootloader) if it will screw anything up long term if your on a more recent one, but if you flash the most recent stuff it should be okay
[Samsung Galaxy S8 & S8+ Cross Device Development] Ogawa:
Just a little help before starting

Ok, I could use a little help to make sure that I'm clear on the how before kicking this off. I've been flashing for years, but have been out of the loop for a bit and while I've read the last few hundred posts, I'm still a bit confused as to the different steps necessary with the different versions of stock.

Anyhoo, I'm running a stock GS8+ - G955FXXU1CRAP is my baseband and I'm on R16NW.G955FXXU1CRB7 - screenshot attached

So, here's what I'm thinking are the steps:

FLASH TWRP

Download Smart Switch from here and install

Download Odin 3.12.3 from here - and install

Download twrp-3.2.1-0-dream2lte.img.tar version of TWRP from here

Reboot to download mode

Open Odin and place the TWRP tar file in the [AP] slot.

Connect your phone.

Hold [VOLUME UP] + [BIXBY] + [POWER] on your phone and then press start on Odin.

Wait for the phone to reboot. DO NOT release [VOLUME UP] + [BIXBY] + [POWER] or you may not reboot into TWRP.

Initialize TWRP

Select "Keep /system RO"

Swipe right to allow modifications

Go to "Wipe" menu of TWRP and you will find "Format Data". Press "Format Data" and type "yes" to continue.

Reboot to "Recovery" to reboot TWRP.

Download dm-verity 6.0 from here and flash

ROOT

Download Magisk 16.0 from here and flash

So, Is this the right process for my build and version?

And, is dm-verity necessary? I'm a bit unclear on it and the difference it makes.

Many thanks in advance for the help!
[Samsung Galaxy S8 & S8+ Cross Device Development] ISF:
For those of you at the beginning, not really knowing how to root your S8/S8+ (Exynos) and install TWRP here an user-friendly tutorial made by me :)

[YOUTUBE]T-XEtUFBwXA[/YOUTUBE]​
[Samsung Galaxy S8 & S8+ Cross Device Development] spawnlives:
Basically that's how I did it but

1. Before entering download mode enable developer options then enable usb debugging first.

2. Note that Odin and smart switch don't play nice together.

3. I believe the dm-verity file is necessary as it disables the data encryption mode.

For more info read the op(page 1) for install instructions.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ogawa:
Thanks. I got most of it from the OP, but was reading through and it seems there are different approaches depending on the baseband you have when you start. It seems some people have to flash a different stock version first.
[Samsung Galaxy S8 & S8+ Cross Device Development] spawnlives:
Not sure I'll be of much help as I'm still on nougat (7.0) and for a few reasons not updating to Oreo just yet.

I have read other threads and forums on installing twrp on Oreo and the process is pretty much the same. Some issues I have noticed seem to range from Odin version,locked bootloader even bootloader version no.

If you have'nt already done it all I can suggest is going back through this post,check other threads and forums.

This link below (bottom of article) was interesting in that some people installed twrp and when rebooted back into recovery to have stock recovery instead of twrp showing up.

[Samsung Galaxy S8 & S8+ Cross Device Development] force70:
You know what your doing but trying to flash twrp onto a device which has a locked BL and doesnt support it?

At any rate you should be able to odin back to stock...doubt its bricked.

If oem unlock is not available you can try this trick. It works for me.

- change date to 8days before, change time zone

- go to setting - software update - check update

You will get error message then reboot phone and go to development option if oem is available.

You may need to try few times untill it work.

Dont flash = you can't mount data
[Samsung Galaxy S8 & S8+ Cross Device Development] orifori:
I permanently decrypted device - it's rooted and TWRP backup is working properly. What will happen if I choose to fully encrypt device (this option showed up in the menu after after phone was permanently decrypted following TWRP installation)? AFAIK TWRP will stop working as it cannot read encrypted containers. But will the phone still remain rooted and working with full device encryption?

if i root my phone

will the warranty go away

im little confused
[Samsung Galaxy S8 & S8+ Cross Device Development] Ogawa:
Ok, followed all the instructions and had it working, but it's crapped out and I could use a little help

checked OEM unlock and debugging

Flashed TWRP through Odin. (took a few times. 3.2.1-0 was what I used)

Booted into recovery

Formatted data

Installed DM Verity

Installed Magisk

Booted up, started setup and decided to reboot to flash the Batman ROM

Tried to reboot into TWRP to flash, but brought up the Samsung logo with "official binaries" at the top

And, it won't even fully boot up, it just powers down after about 10 secs.

So...what now? I've tried to start over and flash TWRP again, but it fails.

I was thinking of flashing the stock firmware and trying to go back to scratch, but am not sure which version to flash.

And help would be greatly appreciated! Many thanks!

Do you have Exynos or U.S./Canada Snapdragon? See the title of this thread? It's for Exynos.

If you have Exynos and can't see it, there's something wrong with your phone or you're looking in the wrong place. We can discuss further, if so.
