Flashing a ROM

​

Yes, you can actually flash any ROM on your device! ROM developers should be informed to use the model number from TWRP to determine what device you are running, to distinguish between the S8 and the S8+.

Our device reports back "dream2lte" in TWRP but the actual model number of our device is "dream2lteks" with a model number of SM-G955N.

Do not flash a ROM that edited the build.prop for the SM-G955N without full system prop modifications implemented, or else Magisk Hide would NOT work.

The steps are simple to flash a custom SM-G955N ROM but must be followed to the T:

1. You've got to trip KNOX, which will void the warranty! But we imported our phones, so who we kidding? You've got no warranty anyways!

2. Once you spent a few heartfelt minutes thinking about the pros and cons, you will have to flash [MENTION=6371894]jesec[/MENTION]'s TWRP on your device following ALL instructions of his guide, including flashing the decrypt ZIP. https://xdaforums.com/galaxy-s8/sam...pment/recovery-twrp-galaxy-s8-exynos-t3595102

3. Pick your ROM, if the ROM requests you to flash BL and CP, you CANNOT flash the G955F versions, as we have a completely different bootloader!!! If they have the G955N variants, then feel free to update it if you want, as this step is NOT mandatory. It IS safe to flash a 955F kernel on your 955N!

4. Place the ROM zip into your MicroSD and the CSC Flasher, but do NOT use TWRP to transfer these files. MTP will stop working Midway (all variants of the S8+, roughly at 1.5gb) so I suggest doing it before going to recovery, or if it's too late, just use a microSD adapter and add it in there. Recommended drive format: exFAT.

5. Flash the ROM as you would from TWRP, depending on your ROM, it may have a debloat Aroma menu. If there's a way to update the BL and CP inside the Aroma menu, DO NOT. Some ROMs ask if you would like to flash a CSC (that you're not interested in), so pick DBT (Germany) unbranded.

6. After flashing the ROM, depending on your ROM, you may need to reboot back into recovery using Reboot -> Recovery to avoid the Device or Resource is Busy error in TWRP...to flash the CSC package.

7. It is highly recommended to use unbranded CSCs but it is not 100%. If you are in Canada like me, the CSC package for Rogers Wireless (RWC) under XAC causes a ton of keyboard force closes and random reboots. While the XAC unbranded default CSC runs better but still has keyboard force closes. There may be an error with mounting and unmounting /preload, a non existent partition on our variant...which is perfectly okay!

8. Ensure that you remember the above steps when you're dirty flashing a ROM update, because if you forget to flash the same CSC from the previous flash, you will lose CSC benefits like VoLTE, LTE-A and wifi calling until you factory reset!

9. If you're looking for root, you MUST reflash Magisk v12+, or else you won't get any MagiskSU green flags. Seems to be happening mostly on our Korean variant.

10. You're done!

Frequently Asked Questions (Buyer's Questions)

​

Q: I'm planning to buy this phone but not planning to root it, what kind of bloat are there.?

Custom SK Telecom Bootanimation with sound

[YOUTUBE]KjJObLpByuE[/YOUTUBE]

One full folder of Korean applications from the carrier, including Samsung bloat that are all Korean-region bounded.

An out of place second carrier label in the lock screen (bottom left)

Settings has two extra options, T roaming and T security. You can get rid of the T security shortcut in Settings by disabling the T membership app using Package Disabler Pro (Samsung) on Play Store. T roaming cannot be removed. Depending on your device's original carrier, you may get the KT service provider entry.

Camera can't disable shutter noise. Korean law.

Bootloader is Korean. Unchangeable.

Q: Are there any carrier markings on the device?

Yes, but really unnoticeable. There are no FCC markings at the back of the phone but just a line of text, and at the end of that line of text just says SKT. It is as natural as a phone that tells you where it was manufactured.

Q: Can I Odin a stock SM-G955F firmware or CSC file?

No, you can't flash anything SM-G955F in any slot of Odin. Doing so will just fail or secure flash error.

Q: Can I use a CSC from a company that sells S8+'s with Qualcomm on my Exynos device?

Yes, but it may need some testing. In Canada, if you have the proper CSC, I confirmed to get VoLTE and Wifi Calling after flashing the RWC CSC. But the XAC CSC may not enable Wifi Calling but will enable VoLTE. LTE-A is almost supported on all CSCs, so you don't have to worry about that.

Q: If I flash an SM-G955F ROM on my device, will it affect my RAM or storage?

No. You will retain 128GB and 6GB RAM on any ROM.

Q: Can I disable bloat apps without rooting?

Yes, but you may have to use a paid app, linked here: https://play.google.com/store/apps/details?id=com.ospolice.packagedisablerpro&hl=en

Search for "SKT" and it is safe to disable them all. Disabling T membership as stated above will disable the Settings shortcut to it to, but T roaming will not disappear.

Reserved 4 ?
[Samsung Galaxy S8+ Guides, News, & Discussion] bidav1:
Thanks for the amazing guide. All working. Btw I saw that latest batstock rom is version 1 not 1.1?

My device now shows that its 955f is that OK? I installed the ilo israel csc so how can I update the rom with that csc without loosing data? Thanks!
[Samsung Galaxy S8+ Guides, News, & Discussion] forsberg78:
There was a system update today. Anyone know the changes?
[Samsung Galaxy S8+ Guides, News, & Discussion] bidav1:
BTW I did not reflash magisk, just downloaded magisk manager from play store and install from there.
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
Yeah I'm in the testers chat on the Telegram link but the model number is just a build.prop check.

As long as you update the ROM with the CSC before booting up, you won't lose any data.

Were you able to obtain root? Depending on your set up, you may not have any root like what happened to me, so I had to reflash. Also I tried a no root option from BatStock and if it doesn't patch your boot image, then you'd be stuck on the Samsung logo indefinitely.
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
Do you know the system update's binary letters? Or just post a screenshot.
[Samsung Galaxy S8+ Guides, News, & Discussion] bidav1:
I was able to fully obtain rom. what I did is after the phone booted up (after the rom installation), I downloaded magisk manager from app store, then clicked on install inside the manager. when the phone booted up afterwards i was fully rooted. also checked with root info and various root apps.

just one thing is not clear to me. now i'm on batstock 1.0 with stock kernel and untouched bl and modem. and with ILO csc from the csc tool.

now when i want to upgrade to batstock 1.1, say a dirty flash to keep data. what are the steps?

1. copy the zip file of the rom and the zip file of the csc tool to sd

2. reboot to twrp, install the rom file dirty flash and not to reboot

3. before reboot, install the csc zip file in twrp

4. reboot

did i get that alright?

thank you !
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
Yes that's correct, because a dirty flash is going to wipe the CSC, since the CSC is located in the /system folder, the ROM upgrade will wipe system and you lose your CSC, but the preferences are stored in /data, so your procedure is correct. If you get any resource is busy errors in aroma, reboot recovery before flashing the CSC
[Samsung Galaxy S8+ Guides, News, & Discussion] bidav1:
thanks ! any news about the update that rolled out today for unrooted devices?
[Samsung Galaxy S8+ Guides, News, & Discussion] DireWolf619:
Thanks for the thread mate.. I was also thinking of making this up...

I have Korean model s8 + kt 64gb.. I am on CarHD 1.3.. Everything is working perfectly.. Before i tried flashing renovate rom 2 bit every time i was struck at samsung logo.. I tried flashing everything like magshik .. Ok thats not the question...I study in china and brought Korean KT version online

I yesterday broke the screen of my phone..now can anyone suggest me what should i do. Can i go to service center and ask them to repair the phone... I just want that i get replaced the screen and get my water resistant back..

My one friend called Samsung care here in china to enquire about the screen replacement and they said that if touch is working then it will cost me around 120 us doller and if touch is not working then cost me 250 us doller....

Can anybody can give me some ideas or suggestions please? Thanks in advance

[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
Bluetooth connectivity fixes and some stability features
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
Just be sure to look at the last 4 characters to see what the new version code is, in this case, AQEB.
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
The reason it got stuck on the Samsung logo was because, as I listed in my main threads, they used the wrong way of detecting model, so it was not installing a kernel for your device and you were booting with no kernel.

Unfortunately, that's what happens if you import a device. But I'm not so sure if Samsung China would be able to help you since your device is not from China. Maybe if you go to a small shop, you could inquire prices there, or watch a video and buy a new screen for yourself maybe.
[Samsung Galaxy S8+ Guides, News, & Discussion] DireWolf619:
Yeah i will go to service center tomorrow...i am afraid to go to small shop because i think they won't be able to provide water resistant after opening the phone...
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
As far as I know with my experience of small shops in Hong Kong, they have kits to apply back on the device for waterproofing.
[Samsung Galaxy S8+ Guides, News, & Discussion] DireWolf619:
Ok thanks tomorrow first i will go to service center, if they decline then i will think what to do...and about the renovate rom.. I somewhat figured it out but didn't got time to test it because it states to wipe internal storage too.. Is it must to wipe internal storage????
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
Just download latest renovate ROM, they fixed the issue. No need internal storage wipe.
[Samsung Galaxy S8+ Guides, News, & Discussion] DireWolf619:
Thanks for the info man... Great help
[Samsung Galaxy S8+ Guides, News, & Discussion] bidav1:
How can we update it? No ota since root.. Should we want for next rom version?
[Samsung Galaxy S8+ Guides, News, & Discussion] forsberg78:
Sweet, thanks!
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
If officially, just flash it in AP, BL and CP from Odin.

If through custom ROM, just update the BL, CP In Odin then flash the custom ROM that comes with that version code. I know BatStock 1.1.1 is already on the firmware, so if you join his Telegram group, you'll get it.

Great thread, thanks for the mention in the main post. :)
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
Seems like the build.prop showing SM-G955N is causing a failure on SafetyNet. Please run only SM-G955F identified ROMs if you care about SafetyNet! Magisk Hide will fail.
[Samsung Galaxy S8+ Guides, News, & Discussion] WahFai:
Thanks for making this thread!

Does this mean that installing BatStock rom will cause SafetyNet fail? Is there any work around or should I use a different rom?
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
At the current moment yes, but you can always edit the build.prop to change all of the 955N stuff to 955F and it should work.
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
To all 955N peeps, I have created a simple TWRP flashable stock image with removed KNOX of the SM-955F stock Samsung tarballs.

I'll be creating a new thread for this as it will be flashable on different models of the phone, such as the actual 955F and 955N. It will be completely barebones stock, hopefully you guys would find some relief that

there will be

a debloated version of something you can actually flash on your Korean variant, as each and every Korean stock tarball contains way too much bloat, and Odin will refuse to flash anything 955F on your device... :(

Obviously you can opt for a custom ROM with tweaks like BatStock and RenovateICE, but for people like me who want to stick to stock as much as possible, this zip would be your rescue zip.

The ROM must be flashed in this order,

0) (Optional) Flash the latest AP and CP, I will also mirror these on my AFH.

1) The stock ROM you will download from my thread (~1.8gb)

2) The CSC flasher by [MENTION=5899304]Tkkg1994[/MENTION] (~1.1gb) [No default CSC will be in the ROM!]

3) A custom kernel by [MENTION=6371894]jesec[/MENTION] or [MENTION=5899304]Tkkg1994[/MENTION] (~20mb)

4) (Optional) Magisk!

It'll be up in a day or two, depending on my testing tonight :)

Stock ROMs will have NO tweaks on it, I will have a script that will automatically compile the newest Samsung source the exact same day then push it to AndroidFileHost, with all broken KNOX features removed, so we will all have the newest Samsung source the same day, and hopefully, without clean flashing :D

Debloated stuff:

- All KNOX stuff by default

- Samsung Pass

- Samsung Secure

Huge thanks to [MENTION=6371894]jesec[/MENTION] for helping me out when I had issues :)

How did you do for S Health ?

Secure folder is so good, bad to loose it ...

[MENTION=3605033]nicholaschum[/MENTION] Any idea for having SPay working without a korean sim card ?

Could you do a small list of CSC working for VOLTE, WifiCall ... ^^

Thanks ^^
[Samsung Galaxy S8+ Guides, News, & Discussion] tanipat:
for camera i got it the stock one work with normal control shutter sound it silent when i silent and it sounded when i turn on sound (it work normally as international model so no complaint here)

S Health to work i use Root explorer to edit Buildprop. just go to /systems and edit buildprop, find ro.config.tima=1 just change it to ro.config.tima=0 and save it then reboot and it will be back working again.

for VOLTE AND VOWIFI, it is depends on your country carrier (Thailand is working normally with 3 carrier here for the Thailand model) so it is easy for me to just choose THL csc and it worked as normal^^
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
At the current moment, no. I believe it checks the bootloader to match the country for SPay. But I don't think it could ever happen unfortunately.

CSC works for VoLTE and Wifi Call, but it depends on your country as well. I may get VoLTE and Wifi Call in RWC CSC but you might not since the configuration is completely different.
[Samsung Galaxy S8+ Guides, News, & Discussion] Mugetxu:
Hey I just bought the SM-G955N model and the loading screen shows SK-Telecom does that mean i can only support korean carriers? Plus when I inserted my country's sim it couldn't find my carrier, will it only show up once I go back?
[Samsung Galaxy S8+ Guides, News, & Discussion] nicholaschum:
Try manually searching for your carrier or manually adding APN settings. If it doesn't work, you will have to trip Knox and flash a different country (yours) CSC

You will have to flash a different CSC using the CSC flasher tool.
