Good source for firmwares? - Samsung Galaxy S10 Questions & Answers

I'm looking for a good source of firmwares, i know the famous sites but some firmwares doesn't seem to be listed. I know in the time os Samsung KIES there were tools which communicated directly with samsung.
For example these firmware builds for the SM-G975Ux aren't listed on most firmware sites but have the December secutiry update with binary/bootloader version 8: G975USQS8IVL1 and G975USQS8IVL2

All the big sites have ROMs for that phone (same one I have). There is no "Ux" model... it's *U or *U1, with the latter being unlocked. IF you search for U1 ROMs you have many selections, but most get the XAA version which will usually change carriers automatically based on the SIM card.
The latest BL=8 version I see there is https://www.sammobile.com/samsung/g...M-G975U1/XAA/download/G975U1UEU8IWB6/1741280/ which is the February 2023 security update. I believe this is the last one we are getting (but I could be mistaken as there may be 1 more security patch, I don't remember).

There's U U1 0 W F N .... I'm looking for the oldest firmware with binary version 8, but it seems the sites don't show all firmwares available.... i'm looking for the oldest firmware with U8 bootloader (or any compatible bootloader with binary 8 version), i could have a look at all sites and try my luck... but they don't seem to have all data. but like i said i prefer some original source xml files... i saw some url's to original samsung servers but can't find them anymore.
There is already a firmware available with the march update.... but you have to be lucky to find them... i'm looking for original sources. like update.zip's and such
Found the first one....

I'd recommend around sammobile and samfw. These are the two sources I use the most

hey!
after I wanted to update my g973f from "G973FXXUGHVK1" to "G973FXXSGHWC2" (I tried odin 3.13 and odin 3.14) and an error occurred, I can't install anything anymore... recovery and download mode work, and I can also flash the original firmware, but the device no longer boots into the system! even custom roms don't want to boot anymore
Can anybody help me further?

Right now I don't even care if I get the original firmware or a custom rom running... I hope I didn't brick it (((

My old device was a G930F, its unbreakable make sure you flash the right rom and wipe data and dalvik cache after flashing.... THis ons is locked so it doesn't have fastboot. My G-930F came with fastboot enabled so you can always fastboot a recovery.img. like TWRP
Did you try to download TWRP from twrp.me and "fastboot boot twrp-3.7.0_9-0-herolte.img" ? it should boot to twrp in fastboot mode (hold volume down + home + power).

1. is your KG status is broken?
2. Is your bootloader unlocked?

You know how to flash lineageos through twrp right? and how to use odin?
Maybe flash lineageos to see if everything works.... and then revert to original software. Be sure to wipe cache/dalvik and userdata

Yes, I know there are many other variant firmwares out there, but for a U phone (snapdragon) there is really only U and U1... the rest are incompatible.
There is no "older" firmware with binary 8, because the firmwares are packaged with the proper/compatible binary already. Basically, the "binary" is the bootloader version. On Snapdragon phones, you must have the proper BL/binary to flash, as you already know. You can't interchange the binary/BL with the ROM and security updates because they are not made that way.
The update.zip you're looking for are updates sent by Samsung directly, and they can update the ROM (and Binary) from one stock version to another... but, again, they will update both the binary/BL as well as the ROM, so they can't be broken up to only do one or the other.
It sounds like you're trying to get to an older ROM version (for whatever reason) with an older security patch level as well? Basically, this cannot be done on Snapdragon phones. Once you're on an updated binary/BL, you're stuck there (at least today you are).

I solved the problem! I had unlocked the bootloader, but I also had to deactivate verity via CMD with twrp+adb "adb disable-verity"
ok i've solved the problem now, but does anyone know why i couldn't even start the original stock roms? Actually, the stock ROM should set everything to factory settings...

I've tried different firmwares, its all about snapdragon. You can also flash SM-G975W parts and other snapdragon variants.... there's a lot of variants out there.
I first upgraded and then downgraded to the parts i wanted and am on a rom now with security patch level December 2022, as long as the binary version is the same there's no problem. I've got the latest modem installed and the oldest firmare and bootloader for the latest binary version, i can upgrade or downgrade my bootloader. I already asked someone before if this was possible and if he could confirm because before i was only able to flash CSC and AP i think.
If there's no updates comming anymore why not downgrade and wait for a new leak
I'm also sure we can unlock the bootloader, i'm trying to make an lposed module. I've installed lspatch and lposed and they work fine for some modules. The bootloader unlock has several prerequisites (properties and such) if i can make it look for other properties or something like that we might get an unlock option. Also it looks for an encrypted file on EFS, if someone with an unlocked samsung phone could copy that file we would be a lot further.
It's called /efs/sec_efs/sktdm_mem/encmembership.txt and should be an encrypted file, also if anyone knows how to set ro properties without root (like a stub before the preference controller starts) this would be very usefull.

[HOW TO] Return to stock

Don't you hate it when you flash something and it puts you in an unrecoverable state?
Does it aggravate you to no end when you flash something and then all you can do is go into bootloader and nothing else?
Well, have no fear Motorola Z2 Force users! Your issues will be resolved!
Reasons for using this method:
If you haphazardly flashed a ROM, and now can't boot.
If you tried flashing an audio mod and have issues getting things to work.
If you accidentally (or purposefully) deleted a file and now can't OTA.
Anything else that you can do to soft brick your device.
This zip will fix that and put you back to stock.
You then can update.
If you rooted and cannot update but want the update, this will make your phone clean to accept updates again.
Now, to the meat of this thread. In post two, there is flash all zips for each patch version and instructions on what to do. This does need an unlocked bootloader.

Great, So you've read why you might have borked your phone!
Now, let's get it fixed! Below is the link to the only flashall bat file I currently have. This is a simple process to do. There are some requirements though.
Requirements:
Correct drivers (ADB and fastboot is included in the utilities zip if you don't have minimal adb and fastboot installed, or don't have the SDK.)
Over 4GB of RAM.
How to fix your phone:
Download the Utilities zip
Extract the zip to it's own folder
Download the flash all for your device from the options below.
Extract the flash all zip into the same folder as the Utilities.
Run the Flashall.bat file
Watch windows command prompt put your phone back to stock!
This process can take up to 10-15 minutes depending on USB connection and your PC
Disclaimer: I did not personally test the zips below besides the Sprint and T-Mobile ones. These are the official Firmware links from the Motorola Firmware Team. My only contribution is this thread and the utilities zip.
Disclaimer 2: it is never suggested to flash a zip not intended for your device/major patch version. If you're on Oreo, DO NOT FLASH NOUGAT. (I flashed T-Mobile to my Sprint phone for testing purposes and so I can tell you what it does. I lost all sim functionality and had to do some wonky stuff to get my phone back to working shape... Word of advise: don't do it.)
Disclaimer 3: if you have minimal adb and fastboot or the Android SDK, please be sure you update to the latest fastboot. The exe files included in the zip are for those who don't have a development environment set up.
Downloads:
Flash All Utilities
AT&T Oreo Flash All
Sprint Oreo Flash All
T-Mobile Flash All (Not official download link, but official files, See here)
USC (check version) Flash All
Verizon Flash All
NOTE: yes, it's in the Z2 play folder. Motorola Firmware Team did not make another folder for our device. Check the file name. It has "Nash" specifying the Z2 force. If you ask why it's in the Play folder, I will not respond.
If you have any other official links, I will add to second post and give proper credits to who found the zip. Only perm links like the AFH ones I posted.

I was going to add yours in but kinda got busy
Thanks for this! I flashed a modified boot.img for root to get my phone unlocked, and flashed the stock kernel back, but I couldn't update to the September patch. After flashing this, updates are working fine. A bit of a lifesaver!

when i did this (i did this so that i could go back to stock with a locked bootloader which as of writing i just realized would work fine if i just did fastboot oem lock without anything else, goddamnit) it told me that a different operating system had been installed, even though it's (presumably) the same os. what's going on?

That is a "permanent" flag that triggers when you flash something unsigned and not from Motorola. I.E. custom boot image for root. Reason it's in quotes is because we don't know how to return it back or if we even can.

So Sprint Z2 can't get GSM unlocked by flashing ROMs from other carriers? Any idea how it can be unlocked?
How to get back to software status official in bootloader menu? I did managed to do it with T-Mobile version but cant get that from this one.

A quick question sorry for newbie question in advance, I return to Motorola after a long years a lot changed
I got a Moto Z2 from a friend (he no have knowledge of rooting and modifying) which he got from his cousin in UK so when I got it seem it have a Tmobile sprint hybrid rom installed and google warning screen on the start, it is my guess it is Sprint's phone but I am not confirm.
XT-1789-03 is etched on the bottom near the and by search on google it is showing sprint so please if anyone can confirm -03 is sprint or not? imei is also showing the clean on the sprint site but it NOT definitely saying this phone is sprint.
Please someone tell me if I can flash this and get back to normal and get the OTA updates.

Note 8 soft bricked

Salutations everybody. I haven't had a phone from sammy in a while. Finally invested in a SM-N950F note 8. It's oreo. Tried to root earlier today using the pinned guide in the Guides forum. After going through the process, and flashing twrp. Then formatting data. And rebooting it to twrp (which I did a couple of times) (May been where I messed up,but it doesn't seem likely to me) I flashed the oreo n950f oem issue zip and rooted with magisk. Upon rebooting & enabling dev options. The oem toggle was missing. The guide didn't say what to do in the event that it was missing. Just that it was safe to reboot if it was there, and enabled.
Me being rushed for time rebooted anyway, and now when I try to boot up I get only official released binaries may be flashed, and the phone shuts off.
I'm aware I can restore to stock via odin. But I have a couple of questions.
A. Can I use the same odin version I used for the root process to return to stock, or do I need a different one?
And
B. There are loads of options for country and carrier on sammobiles site. I bought the phone used and have no idea of its country of origin. There is a version that says unknown for country and (bat) for carrier. Is that one safe to use, and is there any difference between the firmwares other than carrier setting being preinstalled (would be my guess of the only difference.)
Thanks in advance for any help you can provide.
This msg Only official released binaries are allowed to be flashed cause of the new security patch lock which called RMM or KG and since u were rooted before then u got this error that's cause you flashed a new BL to your device or you were connected to internet before editing kernel to prevent samsung to add the new lock to your device anyway a normal flash through odin will solve your problem and your device will be ready to use it again without any problems but also without any custom files like TWRP and Magsic which means u will not be able to root your device before editing kernel to remove the new security patch lock

Using odin 13.1.3 is recommended.
As you have the N950F, it is part of the multi OXM CSC, so you can flash the filmware for you country and carrier if desired (N950F)
If you want to root, I suggest just flashing a custom rom or kernel, as they have been patched for the RMM KG state issue.

[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?

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.

how to root , flash custom recovery and custom ROM on galaxy S10 5G (G977N)

Hello folks !
I just bought a galaxy S10 5G G977N and I found it difficult to work my way through all the changes made in rooting/custom roming smartphones (I had a galaxy S7 before that, it was pretty easy).
What I read for now :
How to root with magisk : https://topjohnwu.github.io/Magisk/install.html#samsung-system-as-root
How to install TWRP : https://twrp.me/samsung/samsunggalaxys105G.html
What I learned :
Rooting device is far more complicated than it was before. If I do so, I won't be able to update stock rom OTA, I'll have to reflash a patched recovery (AP file) for every update. This bothers me because its not convenient, and because messing with odin is way riskier than flashing zip from custom recovery and may brick my phone, so the less I use it, the better I think.
Plus,booting the phone will be a pain in the ass, having to do the right key combination
Installing TWRP will not change that.
What I'm wondering :
I'm a bit confused on how I will be able to update stock ROM (The way I understand it, I'll have to reinstall TWRP after each update)
And I'm even more confused about how all of this will work with custom ROMs.
Let's say I root my phone and install TWRP. If I want a custom ROM and keep it rooted, how will it work ? I'll have to unzip the ROM, patch the AP file with magisk, rezip it, flash it with twrp and voilà ? And I'll have the same key combination issue where I'll have to boot a certain way to access the rooted ROM, and if I don't, I'll boot on an unrooted ROM ?
Thank you a lot for helping. I'm really used to rooted and unbloated ROM (God I've forgotten how bloated stock ROMs are !) but the complexity of the operation stops me for now. I don't want to brick my phone and I'm not sure I'll have the courage to do all of this every 3 month for each update.
Hello!
This thread is a bit old. But since I had to dig the forum to find what I was looking for (and update my knowledge), maybe my answer will be useful for somebody else.

Yep. That was a shocker for me, coming from a 7 year old phone.

I agree! Thankfully, somebody smarter than me took care of that. You can thank ianmacd for his multidisabler (GitHub project's page; xda thread).
One of its functionality is to disable "Stock recovery auto-restoration".
If you want to see a guide for how to use it (for S10 5G Snapdragon only, but same principle apply for the others), afaneh92 wrote one! Same thing by corsicanu, but with official links to download TWRP (and his repository for the other stuff), and it works with other versions of the S10 too. corsicanu got his tools here if needed.
Be careful, you must format /data after disabling encryption with multidisabler. Back up your data first!
I won't be able to update stock rom OTA

No OTA if you root.
You can still upgrade the stock kernel/firmware to a newer Android version manually. Afterwards, flash TWRP, then flash multidisabler again, then run multidisabler in terminal. And, all good!
(Reflashing stock firmware disables "multidisabler")
Check for firmware updates on Samsung's changelog page.
Replace your S10 model number and CSC code in the link below:
doc.samsungmobile.com/YourModelNumber/YourCscCode/doc.html
To know which CSC you have:
Go to Settings > About phone > Software information > Service provider software version
The last line should show the current CSC (three characters), e.g. mine is KTC for Korean KTC devices.
doc.samsungmobile.com/sm-g977b/ftm/doc.html
corsicanu makes it easier for us, here is his github page for the S10.

To flash the ROM the first time:
Flash the ROM with TWRP (adb sideload), Format data/factory reset. Formating everything will reenable encryption if you had multidisabler installed first. I think. So I guess flash it afterwards, and format data again?
For example, you can follow Lineage OS's guide. But they don't take care of vbmeta, encryption, and other issues. I'm not sure why.
To update the ROM, it's easier: no need to reinstall multidisabler after a dirty flash. (Lineage guide to update their ROM)
I'm dropping some links you might need:
To download the last version of Odin (odin3-v3-14-1_3b_patched-zip as of date): realbbb's XDA thread.
All the versions of TWRP for the beyondx (G977B and N, maybe other letters too )
Ok. That's all for now. Good luck!
