SM-G960/G965/0/U/U1/Android_10_Root_RMM_Forceencrypt_Remover_Add_US_Carriers_Fix_Safetynet_AIO

Must Have An Unlocked Bootloader To Do This!
Must Be On One UI 2.5 Firmware Or Updating Too One UI 2.5 Firmware to Use
This An odin tar file I have created to flash along with stock odin firmware to automatically install TWRP recovery. The tar file will also automatically install magislk root along with remove force encryption and patch bluetooth library file. It will also patch safetynet and install decrypted csc files. No flashing of zips is required. There are 2 tar files too choose from one will add all US carrier functions to your phone and the other is for Non US carriers ​

Keep up the good work! ??

Sorry for the noob questions.
If I am reading this correctly, it should work on my G9650 that is currently already rooted and running @stang5litre rom, correct?
And this would upgrade to android 10?
Can I roll back to Stang's rom or is this a one way street?
Also, do you have any screenshots of what this Rom looks like?
Thanks in advance.

I'm getting a phone encrypted message upon restarting from twrp, any ideas??

Ignore it. You can access internal storage and mount data correct?

Yes its for g9650 and yes you will be android 10 and you can only roll back if that rom is v6 bootloader

Thank you very much for your work sir
Just one question, does this work for the g9600 model? why I tried to install and I got an error

I'm sorry I didn't specify, it wasn't however in twrp, when I tried booting into system it said system is encrypted and I need to enter a password to get into my phone. I fixed that issue! I had to instead of deleting data and cache, I had to format data and enter yes to confirm formatting entire phone. I restarted it hung then restarted again, I was finally in, I then came into another error as my setup kept crashing when trying to restore from google account. I flashed that zip that you posted for samsung mods, it got passed that. I finally got into the system and passed the setup, the fingerprints etc pin anything locking the phone will not work... is that normal? as of now? Plus I can't get my samsung account to work at all, it keeps saying to sign-in again to continue using my account, sync is broken. I can't get any photos back etc as of now,. as eveything is on my samsung cloud and I really don't like my phone in-secure as I always have nosy friends. I'm pretty good at trouble shooting but these right now are my issues. Magisk is working and functioning properly, idk if it's a problem with magisk because my other device (Huawei Honor 8) has the same issue with Magisk and the password on lock-screen. My s6 Edge Plus has no issues with Magisk 20+ though and has lock screen functions etc. fingerprints.

Im sorry for some reason the OP reverted back to an early state on my direction. I updated them too state that you should add any accounts or set any security until you are through setup. You may not want to restore data and start fresh on this as this is not a sm-g9650 rom anymore its a sm-g965u rom. Just by chance who is your carrier? Fingerprint and all lockscreen security works fine for me so maybe wipe data and go through setup again without connecting to wifi or adding any accounts or security

My carrier is at&t

Downgrading from Bootloader 5 to Bootloader 4 in Note 9 Exynos

Hi everyone,
I had updated my Galaxy Note 9 with March 2020 update and I am one among many poor souls who are suffering from display discoloration, horizontal lines during low brightness and over heating.
- I have tried all possible methods as suggested by Samsung team in their US community page, tried factory reset multiple times, nothing worked. Took screenshots of the screen and shared it to other to check if the problem is with display, but the screenshots were just fine, no colour distortion or verticle lines. So i am of the opinion that, its basically software glitch in March update.
So, I have some following specific queries. I tried looking for these queries in the forum but did not find any, so, have collated all my queries below:
- My current Bootloader version is 5. Is there any process by which i can downgrade my Bootloader from 5 to 4? I would like to go back to January update.
- If I root my phone and install custom rom (latest version of Linage OS. You guys can suggest a good OS, if you have tried one), will the display problem be solved?
- After installing custom rom as mentioned above, can I go back and install stock firmware with Bootloader version 4?
As you can see, I am just trying to find a solution to come out of display problem. Any other suggestions or any tried and tested solutions are welcome.
Thanks everyone in advance

I am facing same issue ...display distortion from 20% to 80% ..after that display looks fine.
I tried to downgrade to pie ..still no success...it has same issue...
I also believe that its software issue or some connection issue

Sue samsung for trying to force user to change screen. Samsung's screen is so expensive. Apple was fined for throttling the iphones.

I have same issue on my N9600... :'(

What is causing the distortion? Sofware bug? Can shot a picture showing the issue?

Ita all over the internet. Just Google Samsung galaxy note 9 display discoloration.

I don't know if this will solve your problem but you would be able to flash a Android 9 ROM on a Android 10 bootloader. If you're like me you hate Android 10. What you do is you flash Android 9 bootloader made for twrp flash the Android 9 rom of your choice. Than flash the Android 10 bootloader that you want via Odin, than fastly reflash twrp for Android 10
For me it works but I kind of jerry-rigged it to work. I regret every day updating to Android 10 but since I'm able to still run Android 9 on an Android 10 bootloader, I'm okay with that.
Hope this kind of help you.

only way is to trip knox by rooting and then flashing an android 9 rom. as you know once it has been tripped you will instantly lose access to samsung pay, secure folders etc. however on the plus side you have the choice of root or non root.

Hi guys,
Me and my mum are experiencing a similar situation.... I'm trying to downgrade my galaxy Note8 boot-loader, everything was working till I press the button to upgrade. Now I cant use any memory card all i see is 'the Sandisk card is not supported' and for my mum's Note 9 when she activates the biometric sensor the phone restarts each 15 - 30 mins. I always bought Samsung but now I'm considering to don't do it anymore...

Hi, ok so assuming we don't care about tripping knox, rooting and flash.. still, how would this be done?
I'm on a SM-N9600 atm, with latest Android 10, rooted and TWRP installed. Where do I find a custom Android 9 Rom (compatible with my model) that I can flash via TWRP?
Thanks in advance

All you do is just flash the android 9 rom. Downgrading the bootloader makes no difference if you have already unlocked it. The whole point of it is for people who are on later bootloaders and still have knox and want to go to android 9 which is not possible without the trip.

Hi @A|ex , thanks for your answer. I still don't know where I can find a custom Android 9 rom, compatible with Note 9 snapdragon (SM-N9600) that I could flash via TWRP... (Assuming it's impossible to flash stock Android 9 via Odin even if my phone is currently already rooted on latest Android 10 (bootloader == 5).
Here on XDA there are some ROMs for the Exynos model but nothing except the 'WETA' rom for Snapdragon model, which is not a full rom anyway from what I understand.
If you could shed some light on this it would be much appreciated: where can I find a custom Android 9 rom, flashable via TWRP, compatible with a rooted SM-N9600 (currently on latest Android 10, with a BL==5, unlocked)?
Thanks again for any help!!

[samsung note 8][revert to stock firmware from custom]

Alirghty so i bought a used samsung note 8 duos. it says it on the back, in the software, in smart switch, heck even the AP and CSC files are infact for a SM-N950F
Here is where the problem is as far as I've figured out, I'll explain what the firmware files are on the device taken from dialing *#12580*369#:
BL:N950NKSU5DSK1
AP:N950FXXS7DSH1
CP:N950NKOU5DSH1
CSC:N950FOXM7DSG1
The phone runs fine honestly but its bugs me that there two different binaries mixed in my phone from what i can tell the BL and CP are from a Korean level 5 Binary (also can someone tell me why security levels matter now?) and the AP and CSC are from F model level 7 Binary
I cant flash anything stock cause its the only thing ive tried and it just wont let me. I am downloading a level 5 binary in *hopes* that it doesnt see an issue with the security levels between firmwares as i always get the fricken PIT error or secure download error orrrr the magic string invaild
All i need is a way to get my dualsims back up and running ive got two imeis on this phone which ive checked online and theyre working also id love it if i could just get all 4 files to be from the same firmware zip
FYI the only thing ive been able to flash is TWRP after which i got to installing no-verity and magisk, Ive been using twrp backups as a failsafe to revert back to the 'original' state my phone was in and thats the only thing working for me so far and i may or may not be a noob in flashing samsung devices

The reason for that is because the phone has obviously been repaired using different hardware from different devices. It's never going to be able to flash normal firmware being that there's different hardware in it. If you want to upgrade that you'll need to use the different versions of firmware for each different hardware.. I'd just send it back if I bought it from somewhere like that.

Revert to Stock
I owns one Galaxy Note 8 SN950-F Indian version,
I have installed one custom ROM for my mobile last month and now i need to revert back to stock.
How can i do it ? Once i installed stock OS using Odin but Knox looks crashed and apps like secure folder not working !
Can i get it done through service center ? When i contacted them they said its impossible as you have rooted once.

Once Knox is tripped it takes a motherboard replacement to revert it.
If SF (Secure Folder) is that important to you, stay on a custom rom that has patched SF patched already.
Literally all TWRP/Rom threads warn you of this, always read the whole OP of any thread in the future.

Yeah. Thats what im doing now. Running on doctor ketans rom.
but im little worried now. Because haven't used any custom roms and worried about security issues.
Can we still go back to stock os ? With genuine updates?

Just follow the steps in the thread below. At the bottom of post #2 you can download "samfirm" for you Pc, it will let you download the latest filmware at a decent speed. (once back on stock you should disable OEM lock so your bank app, Netflix etc will work)

Just follow the steps in the thread below. At the bottom of post #2 you can download "samfirm" for you Pc, it will let you download the latest filmware at a decent speed. (once back on stock you should disable OEM lock so your bank app, Netflix etc will work)

Like I said to you above, once Knox is tripped SF won't work, if SF is that important to you stay on a custom rom that has patched SF. If you're worried about security updates use DeluxeRom which has last months security patch.

Alirghty so i bought a used samsung note 8 duos. it says it on the back, in the software, in smart switch, heck even the AP and CSC files are infact for a SM-N950F
Here is where the problem is as far as I've figured out, I'll explain what the firmware files are on the device taken from dialing *#12580*369#:
BL:N950NKSU5DSK1
AP:N950FXXS7DSH1
CP:N950NKOU5DSH1
CSC:N950FOXM7DSG1
The phone runs fine honestly but its bugs me that there two different binaries mixed in my phone from what i can tell the BL and CP are from a Korean level 5 Binary (also can someone tell me why security levels matter now?) and the AP and CSC are from F model level 7 Binary
I cant flash anything stock cause its the only thing ive tried and it just wont let me. I am downloading a level 5 binary in *hopes* that it doesnt see an issue with the security levels between firmwares as i always get the fricken PIT error or secure download error orrrr the magic string invaild
All i need is a way to get my dualsims back up and running ive got two imeis on this phone which ive checked online and theyre working also id love it if i could just get all 4 files to be from the same firmware zip
FYI the only thing ive been able to flash is TWRP after which i got to installing no-verity and magisk, Ive been using twrp backups as a failsafe to revert back to the 'original' state my phone was in and thats the only thing working for me so far and i may or may not be a noob in flashing samsung devices

I am having this same problem.....my phone got bricked so i was looking for my stock rom but the only stock rom that works with my Samsung note 8 is the korean version which supports one 1 sim but my device is dual sim

Downgrade from Android12 possible?

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.

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 !)

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.

Just got an SM-N960F/DS but it came with blasted Android 10. Can I downgrade to 8.1?

Hi. I'm wondering if it's possible to downgrade the bootloader and everything to Oreo. The entire reason why I bought this Note 9 in 2022 is because GSMArena said it came 'Android Oreo (Upgradable to Android 10)'. Sadly, upon unboxing and turning it on for the first time, it's already on Android 10 OneUI 2.5. Is there any way to downgrade it at all? How risky is it only in terms of bricking the device?
- I don't care about tripping flash counter
- I am comfortable with Odin
- I don't care about losing data/knox/samsung pay/blah -- it's all dreck anyways
- I need my mass storage mode, sd card writable, etc. I refuse to use new crappy Androids
- I care not about security issues so please don't mention this or any of the above. Answers only please
Baseband is FUE5 and build is FUF5
Model is SM-N960F/DS
Thanks in adVanced!

Unfortunately, once the bootloader is upgraded, it will block the installation of any lower version stock ROMs, so a proper downgrade to 8.1 is impossible from what I know.
What can be done however is to install TWRP, and see if someone repackaged the Oreo ROM as a flashable zip, which you can flash like any other custom ROM. It might have some bugs since it will be running on the new bootloader, but it otherwise should work.

Aha. So you're saying there's a chance I can get just an Oreo flash working on the new bootloader without downgrading it. I'll give that a try at some point; this way I'd be able to go back to a newer Android in case of some catastrophe. Thanks!
