I've been all over XDA & cannot for the life of me find any definite information, so if anyone can help or point me in the right direction it would be much appreciated!

I have the SM-G9650/DS with CSC: TPA(Panama)

Running on: SM-G9650ZCU3ARG4

Snapdragon

I'm in the US & trying to get Samsung Pay working again...

OEM Unlock is available in Developer Options...

Is there anyway to modify the CSC without tripping Knox to accomplish this?

Thanks!

Nevermind, just found it:

I have installed the CSC (CSC_OMC_OWA_G9650OWA3ARI6_CL14464819_QB19955299_REV01_user_low_ship_MULTI_CERT.tar) succefully but I still can not install my backup of my EFS.

Finally I installed a stock ROM of chile. The problem the camera don't works in video mode, impossible to take a video (Screen blocked, same with other program). Same with rom Travis, same with kernel 1.2 and 1.2.3.

Same with option "Nand Erase" in Odin. Should I checked the option "Re-Partition" in Odin?

An idea of ​​the problem?

Thanks.

Ps: After doing several tests, the only solution I found was to install a stock rom with the original kernel.

travis82, I think the problem comes from the Kernel, what do you think?

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
I haven't posted it yet because no one has needed it, and I don't want to give Samsung a heads up to patch it because then we will be totally screwed when this happens.

Are you stuck with oem unlock off after flashing a custom rom and using the rmm bypass zip?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Teracotta:
I need to verify if my CSCs are actually tapping in to the maximum CAT combos because the Galaxy S7 is so far connecting to all available bands on 2x2, while both T-Mobile and AT&T are connecting to less than what I know the phones are capable of.

If you will PM the details, I'd like to take a look. If you want to wait until after the S9+ is not supported anymore, that's fine too. I will not be getting another Samsung after this one.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Gbyerly:
I've rooted every phone I've had since the Galaxy S2 and it's always been a fairly straightforward process. However, my experience with the s9+ has been a complete nightmare. I must have tried at least ten times now without any luck. I've followed countless guides to a T and each time I either fail to achieve root access, get stuck in a bootloop, or I receive the "unauthorized software installed" blue screen upon restarting.

I'm at my wits end. I would just like to have root access with stock firmware. I have an SM-G9650. No suffix. It's the Latin American version and my bootloader is unlocked so I have no difficulties flashing TWRP. Has anyone had any luck rooting their s9+ while retaining the stock firmware?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Ellcid01:
Why ppl wont read?:eek: after flash twrp go to twrp flash rmm patch format data and reboot to twrp again and flash no encryption patch
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
Doh sorry I had this thread mixed up with another!

To get access to the service mode you need to do the following:

su
echo -n ON > /efs/imei/factorymode
echo -n OFF >/efs/imei/keystr
setprop sys.hiddenmenu.enabled true

If you are using magisk, replace the last command with this one:

su
resetprop sys.hiddenmenu.enabled true

After this install shortcut matter (lite is fine) from play store and scroll through the system app list of activities until you find modemservicemode or rilservicemode and fire up the activities listed there, one should make it pop up

This works on the 9650, I have no idea about the s7. Maybe try the s7 forum?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Gbyerly:
Thanks for the reply. I have read this thread in its entirety and I followed beachmiles' instructions on page 56 during my last attempt which soft bricked my phone. In a prior attempt, I tried installing the custom rom from this thread and my phone was unable to connect T-Mobile's LTE network so I ended up reflashing the stock rom. I've tried varying the order in which I flash the rmm and no encrypt patch and data wipe, as well as different versions of the two patches to no avail.

I would just like to root my phone while retaining the stock rom and kernel. I'll follow your instructions verbatim if you can clarify at which stage I should flash SuperSU or Magisk and which version of either I should use. Thanks

Es verdad que no es facil obtener root en este dispositivo, ya que no se da la ayuda sufiente para explicar el proceso como en otras publicaciones , pero dejeme decirle que con la paciencia sufuente lo he logrado y tengo ROOT en mi s9+.

PASOS

1.- Verificar que tengas activo OEM

2.- llevar kener kernel 1.2.3 (otros causan reinicios infinitos) a SD (NO INTERNA)

3.- Ir a modo download

3.1.- Flashear a travez de Odin el ultimo twrp (DESELECCIONAR REINICIO INMEDIATO)

4.- Al termniar el flasheo , reinciar en TWRP, ir directo a format data (yes), reiniciar nuevamente en TWRP

5.- Instalar kernel (NO SIRVE PARA GRABAR VIDEOS ) desde SD, reiniciar sistema

6.- al iniciar sistema , nuevamente ve a TWRP e instala magisk 18.00, reinicia.

7.- DISFRUTA DEL ROOT!!!

__________________________________________________________________________________________________

It is true that it is not easy to get root on this device, since there is not enough help to explain the process as in other publications, but let me tell you that with the patience sufcedente I have achieved it and I have ROOT in my s9 +.

STEPS

1.- Verify that you have active OEM

2.- bring kener kernel 1.2.3 (others cause infinite restarts) to SD (NOT INTERNAL)

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Gbyerly:
Thank you! I will try your method next week as soon as I'm out of the prenormal rmm state. If it doesn't work I'll try flashing the no encrypt and rmm bypass patches before flashing the kernel.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Gbyerly:
It worked! No flashing any other patches required either. However, like Chalofito said, video recording is broken with the travkernel v.1.2.3. Hopefully the klabit kernel solves this issue.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] chalofito:
The kernel of [MENTION=4168602]klabit87[/MENTION] works without problem, there is no error and recording of video, and without problems of WiFi, everything to the one hundred, alone, besides that there is nothing to patch anything, just install the kernel and voila, it will already have root and encryption deactivated .

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Gbyerly:
Well I just installed the klabit kernel using the same steps as the travis kernel but I received the unauthorized software screen upon restarting so the rmm bypass patch must be needed. So it looks like I have to wait yet another week to try again. Or I'll just sell it. I swear this the last Samsung I ever buy. What other company punishes users for trying to root their devices?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
My kernel doesn't touch anything regarding that. Your bootloader is still unlocked.

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Gbyerly:
If you flashed the travis kernel before flashing the klabit one then that's the source of your problem. Flashing the stock firmware then flashing the klabit one should fix it so long as you don't encounter the same blue screen issue as me.

How to know which CSC provide which feature ?

Hi, I've passed my whole night searching this site (and others) for a list of each S9+ CSC version and the features they can provide or not (WifiCalling, VoLTE, Call Recorder, Gapps, Samsung Pay, ...) but haven't found any!

As it looks that some of you have this knowledge. Can you please share a link to where I can find this info and clearly knows which CSC would be the best for my G9650/DS which is actually a Oreo CHC (open china?) version manually set to English UI with 2 european SIMs but still showing a lot of things in Chinese and missing all GAPPS.

If for example I switch to HK firmware (TGY) and thus know I will loose Call Recording, is it not possible to backup the app to reinstall it above the HK firmware ?

Wait, so you can install US firmware on the G9650 that is sold in Latin America? I have been tempted to buy the G9650 but I was very concerned that there would be very few firmwares for it.

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Sebastiansm:
No, you can't as far as I know. The U, U1 or any other carrier variants are different from the 0. That could probably change this time, the 0 model was released in more regions than their S8+ counterpart.

You are right, he flashed the firmware from AT&T Mexico. The most likely could be bricking the phone by flashing an U firmware on the 0.
