So I bought my note 9 three weeks ago, it was ATT carrier branded, since I don't need/like any carrier bloat, I just flashed the unlocked firmware to it, until today its working with no problems at all.
So today I learned that the One UI beta came out, I log on my Samsung+ app I got the banner and hit register but nothing... it will simply send me back to the start, probably because i'm offshore who knows. well I started looking around tried with a VPN, tried spoofing my location, clear cache, clear data ( did this multiple times ) but it will simply not let me join the beta.
So I keep on looking and I find this website https://firmware.science/ it will allow you to download the OTA file and flash it using recovery mode!
Sure I wont get the otas automatically on my phone, but I can simply download then again and flash then as they come out.
I hope this helps anyone like that just wanted to install the latest software!
Note!:
This doesn't mean that your are part of the beta, but means that you will have the beta software on your phone!

Does doing that wipe my device? Or do I get to keep my stuff?
I wanted to add this for anyone who kept tapping the register button but was simply returned to the banner like nothing happened.
If this is happening and you dont get a toast msg saying "thank you for your support of the One UI Beta" and no OTA follows, try deleting the (beta) Samsung + app data, rebooting and try again.
I tried all day before doing this and got the OTA 5 mins after wiping app data.

Nope, its a regular update so no need to wipe anything
Already try my apps and games (fortnite, arena of valor) and they work perfect!

Tried everything, to be honest I was just sure that the Samsung+ app would check where you are in the world and if your not on the US it will simply not let you join the beta, the method above worked flawlessly for me!, I'm running One UI at the moment with the dark theme and its awesome!

I have the N960U (T-Mobile) and I am on version ARK1. My version isn't in the list of options? Or will this not work for the 960U from T-Mobile?

Keep in mind that this Beta Update its just for the unlocked firmware, if you want to flash the update you need to first flash this firmware: https://www.sammobile.com/firmwares/galaxy-note9/SM-N960U1/XAA/download/N960U1UES1ARJ9/244752/
After that you will be able to flash the Beta Update

I flashed the same zrkp from firmware. Science on my us unlocked note 9 with arj9 firmware. It did a full factory reset. I would have done so anyway as I always do with major updates.
Working flawlessly so far.
Edit: 2 exceptions found. Themes are not working and cannot connect to my gear s3. Android wear watch works as expected.
Question what happens when you go into settings an click on Software update does it do anything..Just curious..I have the ATT variant an I'm planning on flashing the Unlocked Firmware..

Ok. First of all. Green and gold till I'm dead and cold.
Second of all, if you flash the U1 firmware and sign up for the beta, then you'll get OTAs automatically through settings.
If you flash the U1 firmware and can't get into the beta program, you can download the update.zip from firmware.science. You will have the official beta build, but you won't get updates through settings, because you aren't part of the beta program.
When I run Odin soon as I goto add the AP file Odin freezes an says not responding..I'm useing Windows 10 on my laptop..Any ideas??Also I have put the correct files in odin but it fails Everytime..

That is normal. Just wait. It will eventually load the AP file. If you're flashing the U1 firmware, there is no Userdata file, so you don't use that slot.
Make sure you are using the modified version of ODIN 3.13.1 and run it as an administrator. There are links to it on XDA. Or if you go to the main beta thread there's links to it in the thread.
Just put the files in their respective slots. BL in BL, AP in AP, etc...
CSC_OYN performs a factory reset. HOME_CSC does not wipe the phone. I always use CSC_OYN when switching from carrier firmware to U1 firmware or vice versa, but it's up to you.
After everything is all loaded up in ODIN, put your phone in download mode. Power off. Then hold power, Bixby, and volume down button all at the same time until it boots to a blue-green screen. Then press volume up to continue.
Plug your phone into your computer and hit start. Then sit back and wait. This will take a while.
That's all the steps. If you have any issues, I encourage you to use the search bar on the forum. These steps and solutions to any issues you may run into have been posted many times in several threads.

I'm assuming since I installed the Firmware then the Beta One Samsung + app won't open..then if I click on the Samsung Members app it says Beta but everything i click on say I'm not registered for the Beta..is that because I manually install the Beta update file..So basically Everytime a new beta version comes out I'm going to have to manually install it..

Try an open firmware via Odin of your country if you have a Exynos SOC.
Flash via Odin with your prepaid sim card installed. Normally your csc code changed after this.
Use JDownloader to download free fw updates like websites sammobile.
JDownloader still has a crc check to beware corrupt download archiv.

If he purchased the phone in the US from AT&T as he stated, it won't be an Exynos, UT yes he can use Odin and update manually.

Same is the case with me like OP but I do get notification on Smart Switch that a new update is available. The size is 5GB which means it's a full ROM and not just OTA equivalent file. I need to know if installing the update will wipe the phone or not.
There's no mentioning of this aspect anywhere in Smart Switch help section or on the update notification.

thanks man I've flash U1 software its wiped everything but it works well :good:
now will i receive OTA future updates or i have to do it manually ?
If you want to test for OTA updates, use "settings - software update" manually...
Also, if you want Android 10 beta, download Samsung members app in playstore and register for open beta.
For safe debugging: Activate developer options - oem unlock!

I tried to install One UI 3 android 11 and didn't let me install it's said current software is up to date, this is AT&T carriers so please help me, thank you.
Hi everyone,
I bought a Note 9 a few days ago and its rooted. It has got Android 9 One UI 1.0
I wanted to update the software but it has no software update option.
So I thought maybe I can download the latest software on it through odin.
It is N950F model. On settings, it has the following baseband version: N960FXXU2ZRLR
SE for Android status is showing the following: Enforcing SEPF_SM_N960F_P03_Dr.KetanROM
And bootloader is showing something like this: N960NKSU3CSG3
Now I'm really confused that which firmware should I download?
Can anyone help?
I would recommend that you download and install android 10 to your Note 9.

Use 'samsung phone info' in playstore. Check which csc the phone originally. Download that csc's firmware and flash.
By right any firmware should do but who knows.

once rooted you will lose knox protection, secure folder Samsung health and yes oem updates. even if you flash official again you may receive oem updates but some oem features may not function again. so u might have two options here. one is to re flash via odin the official firmware and use the phone without some features as i mentioned above! also now that our beloved note 9 got the final 2.1 major firmware update it is highly unlikely to get anymore upgrades such as oneui 2.5 but will continue to receive monthly security updates! then the second option is we have some great devs like dr.ketan, AlexisXDA, etc with highly customized roms and many workarounds to get features like S-health and secure folder working and they do keep upgrading the roms and we might even expect to get oneui 2.5 features from them which is excellent. i too am still on stock rom not even rooted but will start having fun flashing roms after my warranty expires for sure! cheers

Hi,
I have a note 8 (SM-N950F) UK. It's unlocked and is still on Android 8.0.0 and the security patch version is 01/04/2018.
When I try do an OTA update it says I've got the latest version of the software installed. I've downloaded Samsung Smart Switch and and that says "Your device software is up to date: RD7(XEU)
I don't think my note 8 has a OEM version of the rom on it. (When I originally got it, I believe it was on the EE network, but wasn't locked to that network).
I was wondering if anybody can help me with the fact i can't seem to update it to Android version to 9 or update the security software.
The details are:
AP: N950FXXU3CRD7
CP: N950FXXU3CRB9
CSC: N950FOXM3CRDC
Don't really know what the above means, but would like to update the ROM to Android 9.
Many thanks in advance for any advice you can give.
Terry.

BACKUP First!!
On PC: (computer)
-Download samfirm.exe or frija
-Download latest Odin version (can be found in sammobile.com firmware section or google search)
-Open up samfirm.exe or frija use : SM-N950F and XEU in the search fields and download file (~4.8 GB File) and unzip the zip file.
-Open Odin and put PHONE in download mode and connect to PC.
-Place the 4 files in its correct place:
BL = BL-FILE
AP = AP-FILE
CP = CP-FILE
CSC = CSC-FILE or HOME-CSC FILE **
** CSC-FILE WILL DELETE EVERYTHING and bring back to factory settings (like doing factory reset!) Backup first before choosing this file.
** HOME-CSC FILE will keep data intact
So choose only ONE File!!!
If you run into bugs after update do a factory reset!
They're YouTube guides on how to use Odin and samfirm.exe or frija!
But beware that you CAN NOT go back to android 8 period! So make sure that you really want to go to pie!!
Just to add to what Bluephnx said, the link below will help you on how to use Odin, but also has the download link for SamFirm. (For region in Samfirm, use either XEU, which is UK and Ireland, or BTU, which is UK, or you will get carrier bloatware. You can obviously flash carrier filmware if you choose)

Many thanks for that. Much appreciated.
I'll give what you suggest a go.
Really don't understand why I can't do it OTA tho', would there be something wrong with my phone to stop OTA update working?
And is there any reason not to go to Pie (9) and stick on 8 that you know of?

It just glitches/bugs out sometimes. It has happened to me before, but once flashing via Odin, it usually resolves the OTA problem. You could try a factory reset, which can sometimes resolve the OTA bug, just back your data up first.
I honestly can't remember what Oreo was like to make a comparison for you, but some people do hate Pie, where I have been very happy with it since it's launch.
Here is a little explanation of Pie on the Note 8 on YT that you may find useful.

Did you ever do the OTA update yourself before on that phone or did you just buy it on AP: N950FXXU3CRD7 CP: N950FXXU3CRB9 CSC: N950FOXM3CRDC? If it's been that way since you got it then the most likely answer is that someone else updated it using a version of firmware that can't update via OTA and the only way to fix that is to use odin and flash the latest version of firmware.
I didnt spot the message about losing GearVR and now having upgraded my GearVR is not functional. It says I cannot go back but... this is XDA so, can i ??
Also not sure if I can re-install the Oculus GearVR app (can't see it on PlayStore) so does anyone know which APKs I need to install as well?
on my s10+ i get se same Issue. According official samsung information, it seems that gear VR do not run on android 12. I did not find any solution for now.

Sorry don't know anything about gearVR, but no, if the bootloader version has increased, which I believe it does when going to A12, then you can't downgrade.
I'm pretty sure there is no xda 'work'a'round' for that, haven't seen one and everything I've read indicates not possible. Do some searching I guess to be positive, but one prereq to bootloader unlock is being on a specific BL version, and even their directions indicate if you're above that version, nothing you can do.
cheers
Thanks for replying... I guess I am boned
I successfuly reverted to Android 11 G975XXSEFUJ2 from Android 12 since I saw issue about GearVR...IF you are on first release of A12 you can downgrade.
Flash all A11 stock firmware package and choose CSC instead Home_csc !

You have the S10+, from what I see, the most recent BL version is 6 on both a11 and the new a12, so that fits the requirements.
It looks like for at least some of the S10 firmware upgrades, the BL version changes, thus u cannot go back if that's the case. Not all A12 updates are out for the S10, so we don't know yet if the BL version will change for them.
Yes.I think they left compatible downgradable bootloader for those users who didn't saw info about GearVR support as a last chance to revert.
I presume,as we learned from previous updates, in future releases of A12 downgrade will not be possible because of their privacy paranoia.

I have the S10 and from what I can tell the BL version is also 6 on my A12 update.
Does this mean I can just use odin to load a "compatible downgradable bootloader" and I will be able to downgrade back to 11? Does my phone have to be unlocked to do this?
Assuming I back up all my data, will I be able to go back to 11 without compromising my xfinity number, security, ect.? I am simply looking for the best way to just revert back to 11 and reload everything I was using before.

Does this mean I can just use odin to load a "compatible downgradable bootloader" and I will be able to downgrade back to 11? Does my phone have to be unlocked to do this?
Assuming I back up all my data, will I be able to go back to 11 without compromising my xfinity number, security, ect.? I am simply looking for the best way to just revert back to 11 and reload everything I was using before.

Well as far as I know you can, but that's from what I've read, not from doing the exact scenario you speak of. Sometimes we just have to try it to know for sure. I have read for sure the if the BL isn't the same version, you can't go back. And no, the phone does not have to be unlocked.
good luck

Thank you for your help!
I figured the most recent update of A11 from
Galaxy Firmware - Samsung Galaxy S10 SM-G973U (CHA) | G973USQU6GUJ3
This Firmware flash for Samsung Galaxy S10 with the Phone Model Number SM-G973U for region 🇺🇸 United States with CSC code CHA and R(Android 11) OS.
galaxyfirmware.com
is what I would need.
The Baseband I have from A12 currently is G973USQU6HULD, so from what was said here the BL ver. 6 means I should be able to do it.
Model #, Country, region/carrier from the above link all match my specs. So if I'm to understand correctly all I should have to do is backup and then use the firmware with odin to flash to my device using tin2404's procedure from above? (Flash all A11 stock firmware package and choose CSC instead of Home_csc !)

I successfuly reverted to Android 11 G975XXSEFUJ2 from Android 12 since I saw issue about GearVR...IF you are on first release of A12 you can downgrade.

Doesn't choosing CSC clear all the app data and basically factory reset it? Wouldn't I want to use Home_CSC, or does it not then work properly?

Update:
Successfully used odin to revert to os11, had to factory reset after odin completed, then I just reloaded my backup.
After more research I decided to block all future updates using ADB and this method:
No more headaches with my software!
Actually, it is neccessery to choose clear CSC to erase leftovers..Choosing Home_CSC brings various of errors possible.
Workaround is doing TWRP backup on SD Card then after clear flashing restoring ONLY data partition.
