OTA not working, how to manually update G981B? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hi there,
my G20 5G (Europe) doesn't find any updates after security level September, and that's been going on for some time. It's not a branded version, so I think I'll need to update manually. Now I haven't manually flashed anything since my old Nexus 5 and have never flashed anything with Odin.
Could anyone point me to the correct OTA-file and instructions how to flash OTA-files without wiping the phone? With the myriad of options I'm not sure which file to get for my specific model.
This is my phone info:
Modelnumber: SM-G981B/DS
Buildnumber: QP1A.190711.020.G981BXXU4BTIB
Basebandversion: G981BXXU4BTIO
//edit:
ok, i found about CSC and stuff, I'm on a T-Mobile software and they are the reason I don't get security updates in time.
Case closed for me, will look in to samkey.

Moto G6 Play - Australian model? I'm lost..

Hi all,
I am at a loss. I seem to have the only version of this phone in the world.I have a Moto G6 Play purchased in Australia. Under About Phone, it shows:
Model
moto g6 play (XT1922-1)
Software channel
retapac
Android version
8.0.0
Baseband version
M8937_26.30.05 7SR
JETER_ROAPDSDS_CUST
Kernel version
3.18.71-perf-g575351b
[email protected] #1
Thu Jan 10 12.07.33 CST 2019
Build number
OPPS27.91-177-2​
I cannot for the life of me find stock firmware for it, and and unsure of how to go about resetting everything. I did manage to root it, using TWRP and sideload, didn't go through the process of making TWRP stick, but it's no problem to get it on when needed. I have unlocked the bootloader. The update to Oreo will not take, and I want to be able to, if I desire, to use a different rom. However, I'd like to update it though to Oreo.
I've scoured the internet, and less than a handful of matches for the model come up, but none in relation to safely doing anything with it.
Does anyone here know where the stock firmware lives? Or how I can manually update the firmware?
Cheers for any help!!!!

https://mirrors.lolinet.com/firmware/moto/aljeter/official/RETAPAC/ there you go. Use the stick firmware from that. Your device is the Aljeter not jeter but it's ok my guide works for your device as while. Just follow it. Don't worry about finding the build prop stuff unless your on pie. Just follow my guide

Thank you NinjaKira. Appreciate that.
Sooo many traps for people like me who only do this once every few years when they get a new phone.
I can confirm that aljeter RETAIL firmware can be used if bricked or boot-looped on updated PIE 9.0 XT1922-1 phones.
I have been unsuccessful in installing any GSI on the my Australian G6 Play.
NinjaKira Guide.
Step 4 - Could not backup. Probably me.
...and
Step 8 - Supplied TWRP 32GB would not let me factory reset, delete or format any phone partitions.
If anyone can get XT1922-1 working with GSI let me know.

Unlock to TMB FW

Hello,
I just got a SM-N970U1 which I'm trying to convert to TMB FW. There are a couple of threads out there however haven't been updated with actual fixes since being posted in Aug 2019.
Issue I encountered, I used odin v3.14 to flash FW (bl/ap/cp/csc) that I got from Frija. It flashes fine, goes through the motions, however in the end, TMB settings aren't applied, meaning there is no splash screen, no RCS/Video etc. The android did update to V10, with UI of 2.0 (this was older version in stock phone), so that part did work.
I did follow the "put sim in, let do carrier initialization etc.", no changes.
I've attempted to flash a few times but haven't had any luck.
Any ideas for a fix? Hoping someone has come up with something for this as the phone has been out for sometime now.
So if anyone in the future needs this info, I ended up downloading the latest available TMO firmware for SM-970U (which is the carrier version of the phone), and just flashed using odin. Cleared the cache, and boom, works!
Not sure about OTA updates yet, as the FW i've installed has the 03/2020 patch.

Unlocked At&t Android 10 update outside US

Greetings,
I'm super new here, also a tech noob so pls be gentle.
I purchased an unlocked At&T Note 10+, and i am living in Malaysia. Little that I know At&T would never send updates to out network, and that I require an At&t SIM in order to get the updates. Currently I am stucked with Android 9, ONE UI 1.5, with no hope of getting anything higher than that.
My question is, how can i get the updates besides flashing a new firmware? I tried connecting to Smart Switch on my laptop, and all it can says is that my software is up to date on SJ8 (ATT).
Hope there's a way other than flashing. HELP.

Hi Mohd Azrimny,
Am in the same boat as you. In Malaysia and have the note 10 plus at&t version. How did you manage? I am using Odin and getting error message connection failed. Not sure what is the problem.
Can you point me from where you downloaded the firmware? I am suspecting that is the culprit.
Thanks!

I'm sorry but I don't think there's other way around, you'll need to flash another firmware.
I have an Unlocked Verizon Note10+, the first thing I did after getting it out of the box was flash the unbranded firmware (CSC: XAA).
Ever since, I've had OTA updates as quick as they're released for N975U1.

I see...tq man. Can u help me out with one last thing? As they are thousands of firmware out there, which one should i choose? Can i simply choose any unbranded firmware (N975U1) from any month security updates n just flash it? I just need a stock ROM, not the latest should be ok as the OTA will take care of the rest.
Right now i'm at nov 2019 security updates SJ8 (ATT).
Thanks in advance.

Well, unfortunately I'm not sure about previous versions, however I'm leaving attached my SW information, my CSC is XAA.
You can download it from sammobile or frija (this is way faster).
Hope this helps,
Regards.
So, knowing you are a noob is half the solution already...
I highly recommend you look for Frija on the internet. Download the tool, search for the phone you have , it is a SM-N975U , and since you want to get rid from the AT&T version, you can install the SM-N975U1 version with XAA as CSC, that Samsung themselves push updates to. Even if they will not, you can always download the next revisions..
I assume you know how to use Odin..

No worries, as Odin and the phone check revisions and suitability. If not the right firmware, it should not write it.

Update Firmware SM-G965U

Hi guys, I recently purchased a refurbished S9+ without knowing the model and it turned out to be a SM-G965U. After a failed software update ("Your current software isn't supported. Visit a service centre"), I've been trying to find a way to update the phone to 'official' Android 10. Does anyone know if this is possible or is the phone locked to Android 9?
'OEM Unlock' is missing from developer settings which (I think) means it can't be rooted with any common method. But is it possible to flash the phone with an official, working version of Android 10?
I'm willing to use any method required (within reason) to update the phone to a working version of Android 10. I'm aware of the "Extreme Syndicate" root method but the bugs / missing features rule it out for me. I intend to get a refund for the phone if it can't be updated to Android 10 so I'd really appreciate any answers to my questions.
Thanks!
You can manually update your phone by using Odin, and download the latest firmware available by using Frija

That's good news. Just to confirm, I can manually update with Odin WITHOUT unlocking OEM in the develop settings? Thanks for replying.
Just confirming that I successfully updated to Android 10 using Odin. The CSC I used is for an American carrier and the phone tries to register on its network but that's easily disabled. Had to be done after every reboot but it's a small price to pay for a working phone....
Hello Guys, I'm currently stuck on G965USQU3ZRLG
I made use of firmware.science to update my S9 plus to this point, but it seems there's no further firmware update for G965USQU3ZRLG to the next update file. Kindly assist, thank you.

Sammoble SM-T970 Firmware flash options help ?

I have a SM-T970 and the June update is out on Sammoble for pretty much every other Tab S7 version except my SM-T970 which for some unknown reason Sammoble never updates on the site ?
Can I safely flash any of the other Tab S7 units firmware's or do I have to wait for the exact SM-T970 firmware ?

Seems the ota update just hit for me anyways with in the past hour
I saw the update showed up on that site around late afternoon. I checked in the morning and didn't see the update. Aynway, I can't do ota update since my device is rooted. So I had to updated it in different way.

If you notice most of the S7 models tend to get the updates way sooner then the SM-T970. Wondering do you know is it possible to update from a different firmware or does it need to be the exact model ?
I just tried downlading the latest BUF5 firmware from samfrew.com. unless you want to pay them for fast speed DL, it will be very slow (my DL estimate was 10+ hours when I tried). They also have an option to save the file to your Google Drive, but i couldnt get it to work. The DL would never start, and the file didnt show up in my Drive.
I instead recommend using galaxyfirmware.com. Just search for the device/model, click the firmware you want. If you want a fast DL without paying, choose the option to share it to your GDrive. It will redirect you to Google where you'll log in. After it's shared to your Drive, just open the Drive app and DL it from there. Or go to drive.google.com in a Web browser.
SamMobile has long since been the most popular site for Samsung firmware downloads, it's where alot of the other firmware sites get their files from. But, unless you pay for a sub, your DL will be very slow. I also couldnt find the BUF5 firmware on SamMobile, but both samfrew.com and galaxyfirmware.com have it.
To my knowledge, the XAR firmware variant is the correct one for the Tab S7+ US region. If you're in another country, then choose a different region when searching for firmwares. So basically, choose SM-T970 for the wifi only Tab S7+. Then choose your region code (XAR, for me). Galaxyfirmware.com makes it easy to know which region a particular code is for. After that, just choose the firmware version you want (BUF5 for me, or something else if you prefer). They sort their firmwares by date released and Android version, so it's easy to see which is the latest.
@Markeee: You generally have to use a firmware that is for the exact model that you have. SM-T970 is the model # for the wifi only Tab S7+, the LTE/5G versions of this tab have a different model #. So, for example, you can't flash a Tab S7 firmware on a Tab S7+. And you also can't flash a LTE/5G firmware on the wifi only model. You can update/flash a "different" firmware, but it has to be for the *SAME* model that you have. As long as the model of the firmware matches what you have, you're golden.
I also forgot to say that (on our tab model) you cant downgrade to a firmware that uses version 1 bootloader, if you're already using a firmware that has a version 2 bootloader. Samsung released an update this year that prevents downgrading in this scenario. As an example, i'm currently running T970XXU2BUF5. The U2 in that denotes version 2 bootloader, U1 in a firmware name is for version 1 bootloader. You can upgrade from U1 to U2, but not backwards. So dont try this, it wont work. And be mindful of what you're flashing.

@Markeee: I've disabled the built in firmware updater in my tab, without root or a PC. You need an app called LADB (paid only, but worth it, or you can compile the app from source code for free), a wifi network, wireless debugging enabled in developer settings, and Android 11. LADB lets you use ADB commands directly on device, which would normally require a PC. You just need to know the package name of the updater, then a single command to either disable or uninstall it. None of this will void warranty, trip Knox. i did this a few weeks ago, tablet functionality isnt affected, everything is running great, no crashes. And i know the updater is disabled, because it doesnt appear in Settings when i search for it.
I just prefer to update manually via Odin, i dont want my tab updating on its' own. I've heard about Samsung forcing updates recently.
September update is available for SM-T970 (EUX). Just updated my SM-T970 (XAR) with it without any issue. Magisk and SafetyNet are fine.
https://samfrew.com/download/Galaxy__Tab__S7+__-Wi-Fi-__/qt4y/EUX/T970XXU2BUI1/T970OXM2BUI1/
@xpdragon: That's nice to know, but I think I'll still wait on Samsung to release the update for XAR US region. I don't really want to flash European firmware on my tab just to get the update, because it would change the CSC code to something that isn't optimal for my location. I've been running the July update ever since the tab was delivered to me, no issues so far, therefore no pressing need to update.

I just saw that on Frija. But after a few months of running Android 12, I've discovered that a few things aren't working as expected. I plan to downgrade back to Android 11 either tonight or early tomorrow morning. Things were working perfectly on 11.

The WiFi only models don't support volte, since they have no mobile data capabilities. Do you have an SM-T970? I used to have that model until I sold it to a friend, it's perfect for him because he only needs to use it on home WiFi, and he has no need to make calls/texts on it.
I still have a Tab S7+, but it's the SM-T976N Korean variant, which supports wifi, 4g, and 5g. I currently have a T-Mobile sim card in it, all is working great. However, I'm pretty sure it doesn't support volte.
If you really don't want to keep it, I'm pretty sure you could sell it on eBay for 300-400 $, depending on its' condition. I bought my Tab S7+ 5g on eBay, new in factory sealed box, for 999$. I feel like it was a good deal, I'm very happy with it. The main thing for me is that it's mobile data capable, a big advantage over my WiFi only model.
