Odin 3 not getting past "NAND Write Start!!" (TWRP) - Samsung Galaxy S7 Questions and Answers

Odin 3 not getting past "NAND Write Start!!" (TWRP) - Samsung Galaxy S7 Questions and Answers

Hello,
I am new to this site so sorry if I'm doing something wrong. My Dad recently somehow (soft?) bricked his S7. Sometimes it gets to the lock screen, but then completely freezes after a few seconds and it has to be forced off. Other times it has given me a black screen with the error:
Bootloader exception
[ RST_STAT = 0x1000000 ]
Exception: do_handler_sync: UNKNOWN(esr: 0x2000000)
! @ @ @ @ D @
pc : 0x8f000a00 lr: 0x8f000048 sp: 0x0206f (cut off here)
'
And other times it has frozen at the boot screen and the screen has become pixelated.
So, after trying Kies (useless), waiting 24 hours and attempting to connect it to adb and fastboot (which I presume isn't really possible), I have resorted to using Odin to flash TWRP 3 onto the phone. However, when I try to flash the .tar (twrp-3.0.0-0-herolte.img.tar and also the latest one), no matter what USB port or cable or PC I use, it always goes straight to "NAND Write Start!!" and goes no further.
Any help would be appreciated as my Dad needs his phone back ASAP.
Thanks.
Side Note: I'm flashing it so I can recover his data, then I'm going to flash the factory firmware onto it.

Hi mate
First what s7 model do you have?
Make sure you are using the latest odin?
oding settings?
flash same or newer firmware on the phone
What files are flashing?
Check this thread is a nice guide for flashing stock firmware

Hey.
I can't check the model as the phone is bricked. All I know is there are only two versions and I'm pretty sure it's not Korea. I'm not flashing any firmware, because I want to get his data off the phone and I'm pretty sure flashing firmware will erase user data. Just trying to get TWRP onto the phone. Odin settings: F. Reset Time ticked, nothing else. Odin version: Odin 3 v3.09. Flashing the .img.tar file as specified in my post.
Thanks.

hi mate
there are more than two versions of S7...... how you know you are flashing the right image? at least you know if you have an Exynos version?
If the phone is bricked how you plan to recover the data the recovery alone may not give you access to the rest of the system and with a custom rom you may have to wipe ( format) the data partition to get access to it ( to disable samsung encryption)
there is a newer odin 3.12.3 try that

All I know is that this is shown when I boot into recovery:
Android Recovery
MMB29K.G930FXXU1BPHJ
samsung/heroltexx/herolte
6.0.1/MMB29K/G930FXXU1BPHJ
user/release-keys
I don't know if that helps at all. In terms of recovering the data, the site I'm following instructions from says there is a Mount > USB Storage option in TWRP, which is why I am doing it.
Thanks

Hi mate
Yes , you have a G930F (Exynos) the TWRP image you were using seem right , regarding this , if you install TWRP in order to access the System /data where all the user apps , info, pictures , mail , configurations ..... is you need to format it , that partition is encrypted only Samsung can access it , TWRP does not support it unless you disable it by formatting it ( AKA erasing everything), mount the phone as USB device it may give access to some partition but it will not give you access to the System/ data ( unless you had formated it before)
If you knew what was the phone CSC you could flash a stock firmware without loosing anything, you use home_csc instead of CSC

Ok mate.......
based on what you showed me, this should be the firmware installed on your phone, only BTU , XEU and EE had a BPHJ firmware in UK
http://www.sammobile.com/firmwares/download/95186/G930FXXU1BPHJ_G930FEVR1BPH1_EVR/
is up to you ..... there should be safe almost 100% sure you should not lose any data.....but there is always a chance
Download firmware from the above link , extract ( un rar , use winrar 7zip) 5 files from the zip file , should be AP, BL, CP, CSC and home_csc , DO NOT USE CSC use all the other 4 files and flash them with Odin ( use the latest download link in the next link i will give you) with the same home_csc as is on your phone there should not be a factory reset .....all data is preserved........hopefully we have it

Alright, thank you very much for your active support. A few questions, obviously I cannot activate PIN in Secure Startup, will that affect anything? Also which slot do I put the HOME_CSC in? What exactly is the HOME_CSC?
Thanks again.
EDIT: Oh and also should I download the firmware from the thread to be safe and just replace the HOME_CSC? Or is the linked firmware 100% fine?

Anytime mate
Your father did not have any pin or password set up before? if that is so use this password default_password when asked for
home_csc goes in the CSC slot in Odin , Country Specific Code it has specific information and or configuration for special services offered by your carrier plus determines when you get an OTA , when you change CSC you have to factory reset if you keep the same CSC ( home_csc) is not mandatory

Download the firmware from sammobile ( first link) extract the 5 files as i told , then you you have two options
1 Extract files ( sammobile) , use the home_csc ( plus the other 4) from them and flash with odin
2 Extract files ( sammobile) save home_csc , go to the second link ( guide) download the firmware from there BUT use the home _csc file you saved ( extracted) from the firmware from sammobile , this is key to not lose any data

Hey.
So I downloaded the firmware from the site, flashed it using Odin, it flashed successfully, but I'm still getting the same issue. Won't boot up at all :/ is it more likely in this case to be hard bricked?

hey mate
Sorry to hear that , try something else , see if you can boot in safe mode
1. Power off the phone by holding down the power button for a few seconds.
2. Press and hold the power button until the Galaxy logo appears on screen.
3. Press and hold the volume down button and release the power button.
4. Hold volume down until the phone has fully booted.
5. You should see ‘Safe mode’ in the bottom left of the screen.
if that does not work my last oftion woul be a factory reset before of thinking on a hardware problem.....

What should I do to install other firmwares with ODIN and keep my files?

Hey guys,
I've read mixed reports that sometimes ODIN erases your files and sometimes it doesn't.
So what determines if ODIN is gonna erase my files or not? I'm not getting OTA since August and I would like to keep installing security patches but I don't what to lose my files.
How can I get the most recent firmware from sammobile and flash it without losing stuff? I remember doing this in S4, is it still possible in S7? What should I look for? Keep same CSC code? Country code? Does it matter?

Thanks, what about this line?
"With Odin v3.11.1, you DON'T HAVE TO ALTER the HOME_CSC anymore! (this was necessary in previous Odin v3.10.7 (that version couldn't handle with the "folder" in the HOME_CSC and Odin would "freeze!); this problem is SOLVED in v3.11.1!)"

Is this unrelated?
So if my CSC Version is G930FOJV1BPH3 I should use any HOME_CSC containing OJV? Or by "same as you have now" you mean exact numbering?

The issue with Odin is no relevant any more , it was an old issue
i meant same home_csc , if you use a different csc than the one you have then is when you get a factory reset .
You can flash any firmware you want , just use a home_csc file containing the same country code as you have , in your case OJV

I can't flash any firmware into my G930F - Please Help!

Hi Guys,
I have a British Galaxy S7 (SM-G930F). I flashed (using the latest ODIN) a Dutch firmware on it that I downloaded from sammobile, but during the proces it was stuck on system.img. The phone doesn't start anymore. I triend to flash back the original firmware but it also was stuck on system.img. I also tried other firmwares, but no luck. The only thing I can do with the phone is getting to the Download mode.
I have done a lot of research online to get it working but no chance. The phone had FRP LOCK before I flashed it. Does that cause the problem?
Could you please advise me at this matter? It is really frustrating.

Hello,

Smart Switch is app by samsung, it's available on their website.

What version of ODIN are you using?

I have noticed you are using DRA9 firmware. You need to use software that also has bootloader in same version. Any other will not work.

How do you flash firmware then if you just have access to the Download mode on a phone and FRP LOCK is ON?

From what I've read FRP only affects the system and your ability to use android and access the partition data after performing a Factory Reset from outside the system (using for example a custom recovery). It should not stop you from flashing a rom in Download mode. I remember myself being in the same trouble as you are, with system getting stuck while flashing. I can't remember how I solved it. I'll search my chrome bookmarks and report back.
Have you tried changing the usb port (the one your are connecting the phone to) and/or the usb cable?

ODIN 3.12.3 or newer
Put phone in download mode
Connect to PC USB
Check Re-partition in ODIN options if changing CSC (Might be an idea anyway)
Flash AP, CP, BL and CSC together
Allow phone to reboot

Newest bootloader (DRA#) locks phone for changing csc and downgrade, but that mainly fails at loading "param.bin" in odin. There is still a possibility to change CSC or downgrade, but you have to mix and match two different firmwares.

Do you mean that I have to Check re-partition? I thought that I'm not supposed to do that!
I tried to flash just the AP, but still the same problem. see attachment.

In case it helps somebody to see the problem, I took a picture of the info I see on the Download mode. See attachment.

That System Status: custom makes me wonder if this could be the issue? That should not really have anything to do with it, but did you try doing "Wipe Cache Partition" and "Wipe Data/Factory reset" in recovery?

Hi Guys,
I have tried other USB-cables... I have tried 4 of them and one them solved the issue.
I can now conclude that the USB-cables I was using were not good.
Thanks for the answers guys.

Well. nice that you found the culprit. Try to buy an official USB cable from one of the Samsung Service Centers near you. The offcial cable is cheap.. like 5-6 USD the 1m long and 8USD the 1.5m long ones

Samsung Galaxy S7 - Germany (DBT) - Custom Binary FRP Lock workaround

Hello guys,
so some months ago my aunt approached me asking me to "repair" her phone which didn't boot anymore after she installled an OTA update.
Now she is been greeted by the Samsung Logo and the message "Custom binary locked by frp lock" and that in an ongoing loop.
What I tried:
> flashing several stock roms (Android 6, Android 7 oldest version and newest versions)
> flashing roms from other countries in EU (UK, Austria, CH)
> flashing with ODIN and KIES (Kies didn't really work tho)
but all of it didn't work.
I fear that I might didn't check if "Re-Partition" was checked in Odion because after several tries and downloading thos Stock Roms with 20 Kb/s I was kinda frustrated when it didn't work..
currently the phone is still boot-looping with the same message as before.
It doesn't matter if I loose every data, as my aunt has a new phone by now!
If the phone has be re-partitioned by Odin is there anyway to fix it or better what are the signs for a Re-Partition?
Thank you in advance!

I am a noob in this, but logicaly reasoning i would say you bricked it bad by flashing away with all kind of csc and firmware down and upgrades.
Your aunt will not be happy.

Well this reply isn't really that helpful...
1st she doesn't care anymore because as mentioned she already has a new phone and said I can just keep it or throw it away.
2nd even if it's bricked there are ways to get it back to working, I soft bricked my old HTC M8 once and restored it.
3rd If you're a noob with this just don't reply, I've never had experience with Samsung phones before thats why I'm seeking for help, if it comes to HTC or LG phones I usually get things done myself. Not in this case tho.

No, as was already stated, it bricked with an OTA, flashing different stock ROMs & CSCs would not brick it
---
Try using Samsung SmartSwitch emergency firmware recovery, I think you'll need the phones serial number (Box / back of phone)
Other than that, using ODIN 3.12.3 or newer with the correct stock ROM & CSC the phone originally came with (newest available release), using CSC and not HOME_CSC to force a reset after the flash should work, then you'll need her google account login to get past the FRP lock

These kind of replies is what I need, thank you! Sadly when trying to use Smart Switch it instructs me to use some kind of "Backup Code" from another PC, I know for a fact my aunt doesn't do any backups and she doesn't even have a proper privat PC. I have a the original packaging IME and such at my hands!
You said flashing with Odin after a flash should work, but should I first use the "HOME_CSC" to flash and then the normal "CSC" to reset it afterwards?

The CSC file is a carrier customization file.: https://forum.xda-developers.com/s7-edge/help/csc-home-csc-simple-t3464835

so in this case with the DBT version it's just the default customization file from Samsung, am I right?
Flashing either Home_CSC or CSC didn't had any effect on the S7 tho, it's still stuck in Boot loop with FRP Lock.
Let's say the phone is soft bricked, is there any way to get it back working, so I can flash the stock firmware afterwards`?

Sadly when trying to use Smart Switch it instructs me to use some kind of "Backup Code" from another PC, I know for a fact my aunt doesn't do any backups and she doesn't even have a proper privat PC. I have a the original packaging IME and such at my hands!
You said flashing with Odin after a flash should work, but should I first use the "HOME_CSC" to flash and then the normal "CSC" to reset it afterwards?

SmartSwitch Windows version shouldn't ask for any backup codes, only maybe the phone serial number
And no, just forget about HOME_CSC, use CSC instead, this will initiate a factory reset after the flash
AP
BL
CP
CSC
Add all 4 parts to ODIN, put the phone in Download Mode (Volume Down & Home & Power) connect to PC USB and hit start on ODIN (3.12.3 or newer)
It "Should" flash the firmware and factory reset, and so long as there is no hardware fault, it should boot into Android and ask for the Google Login that was connected to the phone before it bricked, once you enter that it will allow the rest of the setup to continue and finally to homescreen
It is possible that there is a hardware fault that caused the OTA to brick in the first place, or that the phone is not what it claims to be (Check in download mode which model it says it is, some are faked to look like International G930F when they are actually Snapdragon US models and require different firmware
If it is G930F, then flashing the latest DBT should work fine so long as it is not hardware related

That actually helps me a ton, the Product name is fine it says it's a SM-930F so non US, I guess?
After flashing it with the newest available Stock Android 6 firmware (on which it was shipped originally) doesn't lead to anything it's still stucked in boot loop.
I guess it's a hardware fault then and not recoverable in the first place, thank you very much for your help!
I'm gonna try one last time with an older Version of Odin, maybe this leads to something!
Have a great day

I recommend flashing the same firmware onto the phone. Trying to flash an older bootloader may cause the flash process to stop as downgrading the bootloader is usually not permitted.
Do you know if oem unlock was enabled in the ROM settings? I'm not 100% but this may contribute to the issues with factory resetting and getting the phone to work.
Partitioning is not usually required if the computer is able to read he phone's partition table information. If a re-partition is required, you need to use the correct pit file for the phone when flashing a stock ROM in Odin.

the OEM unlock setting was on default, so off I guess? It was just a regular OTA update and then the phone was stuck in a boot loop.
As *Detection* said it's probably is a hardware related issue I just now noticed that the status LED doesn't even light up if you charge the device (maybe this is an idicator)
I would've gladly used it as a backup device but I think it's just an expensive paperweight by now.
Still thank you for your help, appreciate it!

Sounds like you have tried all you can on your own. Maybe take it to a cell repair shop and have them try to force flash the phone using hardware such as an octopusbox?

Yep G930F is International Exynos so you should be good
Some people have problems downgrading from 7.0 to 6.0, what I meant was flash the latest available firmware for DBT, which is 7.0
2018-04-23
Germany
7.0
G930FXXS2DRDI
As above, the bootloader can be a pain to downgrade, so always try unbricking with the latest firmware available
Same process as I posted above, only using the firmware in this post ^^
Good luck

Yea that doesn't sound good, possibly a faulty motherboard, they seem to be quite a high % of hardware faults of the S7 on XDA, at least that is the outcome of sending them in for repair, but also could be the repair centres way of making the most £

What version bootloader is it running go to download mode to find out top left corner last line of writing will be AP SWREV B:? what number is next to the B you will need to match this to the firmware you are trying to flash for example i use unbranded australian G930FXXU2DRBE firmware and in download mode my AP SWREV is B:2 the number signifies the bootloader its running some exapmes are below for you
AP SWREV B:1 = G930FXX "U1" DRBE
AP SWREV B:2 = G930FXX "U2" DRBE
AP SWREV B:3 = G930FXX "U3" DRBE
You need to match the number next to AP SWREV B:? with the firmware number "U?" For it to work even if it is the same marshmallow or nougat OS it must use the correct bootloader and firmware appropriate to be able to boot i have encountered this problem on numerous occasions if you try to flash a U1 to a U2 binary it will not boot it will not even write it to the memory and you will end uo with a bricked device until the appropriate firmware has been flashed using odin.
You need to also make sure you are using the latest version of odin and have all the drivers installed to your pc for the phone also the status led will not illuminate either while its bricked like this either you will not get this until the OS has been repaired.
If none of this works you could always flash TWRP to it with odin in the AP tab download linage 15.1 oreo 8.1 custom rom for G930F exynos and a gapps .ZIP files move them to an sd card and insert into phone boot into twrp swipe to allow modifications first tap back up and select EFS & BASEBAND and backup this contains your imei number you always should have a back up before flashing a custom rom just incase something goes wrong now after that go to wipe tap the format button on the right and select everything exept otg this will wipe everything and i mean everything OS related which is really want you want to do and also remove the DM verity encryption from the device to be able to boot no after that go to install and select the .ZIP rom and gapps and install after boot you can then re flash stock rom with odin and it should boot however warranty will be void and samsung KNOX will be triggered which means secure file cannot be used nor samsung health app however there is a simple solution i have found to get samsung health running on a rooted device i hope this helps its always worked for me ive purposly bricked my dev G930F so many times on purpose even lost the imei number before and gotten it back without flashing the backup they are really quite hard phones to break software wise.
Thanks

No problem for the late reply yep firmware looks good matches to the BL however i noticed its says your binary and OS are custom when it should say official in donload mode was it previously rooted at some point ? Also have you downloaded the firmware from sammobile ? I would suggest using them for full original firmware packages as they have not been altered and will not apprear as custom when you try to flash with odin, does it complete the flash process and say pass or does it say fail ? Youll also notice when you flash on the screen of the phone it will have a progress bar in sync with odin does it complete the process and reboot or does it say blocked by frp lock if it says blocked by frp lock the firmware your trying to flash is not official you will need official firmware also as it already says custom find a twrp recovery.tar from the twrp website open odin place it in the AP section as soon as it reboots hold the power home ans volume up buttons until twrp appears swipe to allow modifications now go to wipe instead of factory resetting there will be a button saying format on the right tap that and type yes this will erase everything including the custom os it has on it i want you to do this step first before trying to flash the original firmware package as it will wipe everything for a fresh clean install.

I'm not 100% sure about this, but that firmware states S2 not U2
See here, my BL is B:2 but all of the firmware files I can successfully flash are U2

Actually scratch that frp lock is on you cannot flash anything custom to it while it is on just download your firmware from sammobile they have every country and are 100% official i will only download my firmwarw from there it is completely free to make an account and download the only thing is download speeds are slow so will take 2-3 hours to download is the only downfall but gauranteed to be official once downloaded place The files in corresponding slots in odin but with CSC just use CSC & not HOME_CSC this will perform a full wipe
Also maybe download U2 firmware aswell as S2 firmware

Change CSC in Multi CSC ROM without root knox=0

Hi guys, I flash BTU Rom to change my CSC to receive orio faster. after 1 month Samsung rollout orio for my country (Iran) so I have decided flash again my phone because THR rom has Persian calendar, but after flashing my phone I see my phone CSC set on LYS , after search on internet I found out Samsung multi CSC Roms have default CSC , and you can not change it easily.
so I search forums and can't find anything useful until seeing a way in Persian site and it Assured me it is possible. ok talking enough go to work
combination file works. It's a unique file and not available easily, so every website is taking advantage of it by making it paid, some sites charging per file!
I provide combination file for s7 orio file in my host but it is available just for 13 days from today if someone can upload it to Mediafire or something else it is wonderful.
Prerequisite:
*Official ROM from Sammobile that contains the CSC you want
*Combination file for your phone
*Original/Genuine USB Cable, don't use 3rd party cable or you will have a nice expensive brick if a connection is lost.
*Charge your phone/laptop. 50% is fine.
*Remove SIM & SD Card.
*Patience.
*Important- BACKUP. Use Smartswitch (Faster) OR Samsung Cloud Backup. Remember, you won't be able to restore everything (Apps) if you backup from Nougat & then restore it on 6.0.1, so backup with all the options available.
*Balls of Steel--Kidding
1- Download the latest Combination file '500MB' at the bottom from https://firmware.gem-flash.com/ it for s7 G930D/FD http://fs2.filegir.com/akpa/COMBINA...1296_REV00_user_mid_noship.tar.md5-id88783.7z
2- Flash the official ROM from Sammobile that contains the CSC you want. so I used the latest THR firmware available from Sammobile.
3- After flashing the official ROM, Do a Factory Wipe.
2. Fire up Odin, I used Odin 3.13.1. Extract and select Combination file you downloaded in AP AND your country CSC file from official ROM. Two files only.
4. After successful flashing is done, wait for the phone to boot up, it will go into diagnostic/Factory mode, don't panic.
5- Tap Factory IMEI and enter the code *#243203855# ,it will show you a list of available CSCs, choose the one you need and tap install, the phone will reset/restart.
6- Just in case, do one more Factory/Cache Wipe.
7- Power off the phone & enter download mode and Flash it with your country's official ROM. Four files (BL+AP+CP+CSC) Use CSC, don't use Home_CSC.
8- Knox Zero. System Status: Official
9- You can check your active CSC in recovery mode or use Phone info app.
sorry for my bad English.
*be careful the combination build number like G930FXXU2ARA2 and freamware build number like G930FXXU2EREM . the red number must be equal.
**if you have a problem in step 3 you can flash the ap and CSC separately after flash two file, go to recovery with power + home + volume+ after finish the erasing operation select reboot to system.
*** if in step 5 your list is empty, go to downloading mode flash CSC File from your ROM(not home_CSC) and go to recovery with power + home + volume+ after finish the erasing operation select reboot to system.
****if you break your phone don't afraid just go to downloading mode and flash official rom.
Let me know if you face any issues or were successful. It will help others.

Hope this works

It is working, wow!

I tried this and failed ... I got bootloader exception error
Btw, which red numbers must be equal ?
Nevermind, it wasn't displaying red color in the app but it did in my browser. I know bootloader must be same.. I tried this method before you posted, but odin fails at hidden.img and when I boot the phone I get bootloader exception error. Thats quite scary error if you don't know how to bypass it. And ofcourse bootloader version of combination and normal firmware was the same, still I could not succeed.. any thoughts ?
Sent from my S7 Edge using XDA Labs

Hi all,
I was not able to flash combination and CSC together...When trying in two steps, it didn't work neither...after having flashed CSC and rebooted, the update failed with a message like "invalid carrier" or something like that...No way to select a different CSC from factory firmware...
Finally, the following method worked for me:

The return is.

OK
I didn't use RealTerm because it cannot connect so I use PuTTY on port: COM3(which found in ODIN)

G9650 (Snapdragon) CSC Change/ Stock firmware change (NON ROOT)

Hi everyone,
Recently I flashed a stock ROM on my SM-G9650 and wandered around quite some time before gathering all the information to flash the firmware. Now I’m here gathering most (if not all) the information anyone might need to flash stock firmware to your device. This method does NOT require root and does NOT trip KNOX
First of all:
-Disclaimer-
I will not be responsible if your device gets bricked. PROCEED AT YOUR OWN RISK. This is a guide, and even though its pretty straight forward, stuff happens.
Now, onto flashing the device:
A few prerequisites prior to flashing the device:
- ODIN (latest): https://odindownload.com/
- USB Drivers for Samsung: https://developer.samsung.com/galaxy/others/android-usb-driver-for-windows
- An ORIGINAL Cable for your device (Preferably the one that came with it).
- WinRAR or 7zip
- A backup of your data (Optional)
- Patience and time
Ok, now onto the flashing:
First things first: this is a guide for the G9650 (Hong Kong) Variant with UNLOCKED bootloader. If your device model is different, find a thread according to your device.
1- Go to: https://www.sammobile.com/forum/threads/40735-Galaxy-S9-G960-multi-CSC-pit-language , and find the correct Multi CSC for your country/Region. (I live in the Caribbean but chose to use ZTO because it has LTE+ and VoLTE, and the only bloatware is Word, Excel, PowerPoint, LinkedIn and One Drive.). Once you find your CSC, head over to https://www.sammobile.com/firmwares/ and download your desired Firmware. Here is a link for CSC code meaning: https://www.androidsage.com/2017/07...specific-product-code-csc-and-country-region/
2- Once downloaded, create a folder on your desktop and move the zip file to it, then extract. (You can choose any folder you want, I recommend desktop because it is easier to find)
3- Install the USB Drivers previously downloaded.
4- Reboot your pc (By actually opening windows and clicking reboot.)
5- Open Odin and search for the folder you placed the Firmware in.
6- Load BL, AP, CP and CSC (NOT HOME_CSC) onto the correct slots.
Now onto the phone part:
1- Unlock your phone and go to Samsung switch.
2- Back up your data. (If you do not have personal data, then skip)
3- Factory reset the phone, through the settings option.
4- Wait for the phone to boot into the welcome screen.
5- Turn off the device
6- While holding down the Bixby button and the volume up, press the power
7- When the Samsung logo shows, let go of the power and Bixby buttons. Keep holding the Volume up button until you boot into recovery.
8- With the navigation keys, factory reset the phone, once completed, wipe cache and data.
9- Turn off the device.
10- Turn on the device while holding down the Bixby button and volume down. Once the Samsung logo shows, let go of the Bixby button. Keep holding the volume down.
11- Once in the download mode (blue screen with an android), let go of the volume down. Press volume up to select download mode.
Back to the PC part:
1- Once the device is in download mode, connect it via cable and wait for ODIN to recognize it. (a blue box indicating COM port is the indicator that ODIN has recognized the device)
2- Since the BL, AP, CP and CSC have been loaded onto the correct slots, and the device is connected and recognized, go into options and make sure that Auto Reboot and F. Reset time are checked.
3- Press start and BE PATIENT AND CAREFULL, Flashing a firmware takes time. If your cable breaks connection with ODIN, YOU MAY brick your device.
4- Once completed, your phone will boot up on its own, reboot it manually.
Congratulations, you have just flashed a stock, almost bloatware free Samsung Firmware.
If you have any question, feel free to ask.
- To Mods and Admins: Forgive me if I break any rules, this is my first thread. Just let me know what went wrong and I will fix it ASAP

You might want to consider changing the links you have posted for Odin - The latest version is 3.13.1 - The xda link has Odin 3.10.6 and the first Odin link has 3.12.x
Sammobile.com is one of the more reliable sources for Firmware & They conveniently have a link to Odin 3.13.1 as well..
XDA also has a link to the latest version of Odin here:

It's strongly recommended to use Odin 3.13.1 to Flash Oreo Firmware ??

You might want to consider changing the links you have posted for Odin - The latest version is 3.13.1 - The xda link has Odin 3.10.6 and the first Odin link has 3.12.x

The link i posted has ODIN 3.13.1, when you open it in the browser (request desktop site on mobile), under the first image is the button for it. I used that link and said (Latest) so that when you head there you get the latest odin. Also, the link for the firmware is sammobile . I now see that its not very intuitive so i will add the link for the firmware (just have to type the device model and download the desired firmware. Thanks for the heads up

Can I use this guide for my S9+ exynos version G965F?

You can follow these steps but refer to the G965F thread for your appropiate firmware version

I have been out of the Android game since the S7 Edge. I just swapped from iPhone 8+ to a S9+ and love it so far. Question I have is which firmware can I use to debloat my S9+? It's on T-Mobile and I dl the stock firmware from the posted link but I don't think this is the debloated firmware. Any help would be appreciated as I don't know what all this CSC stuff is.

Your previous CSC was TEL? Is it grouped with the VXX in the multi CSC?

I would highly recommend searching the forums for your variant since it is a Snapdragon and probably has locked bootloader. This guide is for G9650, even though the process is basically the same.

I'm familiar with how to flash with Odin but just don't know what debloated stock ROM is compatible.

I don't see a section dedicated to just the T-Mobile version on the S9+.

Make sure the downloaded model matches your device model. For a US variant its pretty hard to find one since most (if not all) put some kind of bloat on them. Search for: Bloat free firmware g965U, and look around.

I bought an unlocked s9+ from ebay and later found out that its country sale came from Panama. My canadian GSM network does work on the device, but certain apps like samsung members show spanish promotions or samsung pay not being available.*
Can the csc code and country be changed in this case so i am able to get the canadian setting and access.
Model: SM-G9650
CPU: Snapdragon 845
Disclaimer: i have never tried alteration of any phone before so im new to this.

JULY Security update for ZTO (G9650) now available
