Which UK firmware gets updates quickest? - Samsung Galaxy Note 9 Questions & Answers

I’m getting a note 9 which was sold by Three (3) so I’m guessing it has the H3G firmware.
I’m with EE and ordinarily I’d flash the EVR firmware on older phones but VoLTE and WiFi calling seem not to be dependent on having their own firmware any more.
So question is, do I flash btu or xeu for fastest updates?
Thanks.

Note 9 N9600 SDM845 HongKong Version to N960U1 firmware ?

Hello,
I have a Note 9 N9600 SD845 HongKong Version, I am using Lyca Mobile sim( Tmobile MVNO) with it .
I have gone through this forum and could not figure out if its possible to install the N960U1 firmware on N9600.
If yes, will it activate all the tmobile bands on N9600 ?
I also have a ATT unlocked note 9 N960U, I have flashed it to N960U1 successfully using Odin. Is it the same process for N9600 ?
Thanks in advance
I there, I have the same phone model and the conclusion that I made was that you can't just flash the u1 firmware like how awe are used to. I had to root mine in order to install tmb software. I then had 4g Lte and wifi calling, but before you root look at what you may be missing out on. It is usaully stuff dealing with knox i.e samsung pay, secure folder, etc.

I dont need Samsung Pay but after flashing to u1 would I get OTA updates or every time will have to update manually for the monthly security patches

Unless you flash the official Samsung software using Odin, you will not be able to install OTA updates. But from my understanding you can't flash USA U1 firmware onto the Hong Kong/International N9600 Note 9. The bootloader will only accept firmware for their respective models. All U.S. Note 9's can flash any of the carrier versions or the unlocked U.S. firmware, but you can't flash the international N9600 firmware... and vice versa.

My S10 just won't update..

It's an unlocked Galaxy S10 AT&T G973U..
I am using it internationally and not with an AT&T sim, so I don't try to upgrade it OTA anymore..
I tried Smart Switch, it says it's up to date. But last security patch was April 2019 and it's running Android 9.
Build and Baseband: G973USQU1ASD7 (According to SamMobile) there's no Android 10 for this baseband.
But my question is, can I flash let's say USA (Android 10) G973USQU3CTB1 or would I need to wait for the baseband for my model?
If I missed something, feel free to correct me.
Thanks!
Having a "U" model means Universal. You can flash any U.S. carrier stock firmware to it. If you have AT&T firmware and want to use T-mobile firmware instead, you can do it by flashing it with Odin.
You can get most firmwares off Sam mobile (Verizon, Sprint, T-mobile). AT&T firmware is hard to come by and you will usually have to pay to get it from a pay site like www.gsm2file.com
Just download an Android 10 firmware and flash it. No matter what it is as long as it's for the U model line.

Ok, thank you very much.
And is "USA" only unbranded? I don't want any bloatware since I am international and I don't benefit from anything they offer.
The G973U phone will only accept U.S. firmware (Verizon, Sprint, At&t, T-mobile, Spectrum, Xfinity, and unlocked U1 Samsung firmware). So if you flash the U1 unbranded firmware you will get rid of carrier bloatware.

Say I wanna get rid of the bloatware, what firmware do I select from the U1 variants? Because I see all of them have carrier names.
If you get it from sam mobile it's XAA from Unknown. The latest is the CTB5 bootloader. I think there's also a thread in the forums here that contains Odin firmware.

Here is the latest SM-G973U Android 10 firmware. It was just released yesterday morning. https://samfrew.com/download/Galaxy__S10__/f6o3/VZW/G973USQS3CTB5/G973UOYN3CTB5/

Question S21 Ultra no Android 12 Update

Hi guys,
I know this was asked, but my case in kinda different.
I have UK version of the phone, BTU and CSC seems to be correct, as others that complained about updates not being pushed had CSC EUX.
Though phone is from UK, it was purchased in Malta as local network operator, not locked or branded to their network, as there is no FW for Malta, they simply get UK unlocked phones.
Any idea how to get updates?
Shall I flash latest FW with odin? Thanks...

Yes you need to flash it with Odin because EUX is a dead circuit.
Thanks. Will do it definitely.
But strange enough is that it's showing BTU not EUX, at least on screenshot.
How stupid is this thing that they kill your phone for updates... :/

I had that issue when i started my phone first time when u purchased it, i use no SIM and that caused the phone to capture EUX CSC instead of NEE (which is the SW for Nordic countries) .. I had to return the phone and i bought another one.

Can I flash a S10 G973U with G973U1 firmware please ?

Hi Folks,
I have bought a G973U samsung S10 but it is not receiving any updates and I am obliged to flash it with ODIN, I heard that I can technically flash G973U1 XAA firmware on it and it will update via OTA, is this true please ? I have the SPR firmware on it. Thanks for your help.
Depends on the carrier. ATT (I assume you're in the USA?), for example, won't do OTA updates unless the IMEI also matches (and maybe some other switches at ATT that we can't change).
XAA should update on some carriers, at least. My XAA updates on TotalWireless (VZ MVNO)... I've actually blocked them because I want to stay on A11 for now.
I believe you can upgrade via ODIN yourself without using an OTA - just be sure to use the HOME_CSC file because the non-home CSC will wipe your data. Any reason you're not doing that? This way, you can control your own updates and timing.
Hello Sofiene.Saidi, look at the official US firmware here for your model, the best thing for you is to take a model for your European region.

Thanks for your anwser Schwinn, actually it is fine with ODIN but each time I need to flask aprroximately 6Gb of firmware, it is somehow risky isn't it ? Can I flash USC firmware and get OTA updates please ?
If you're in France, I don't think you'll ever get OTA updates.
No, flashing the ROM a few times over the phone's life isn't going to affect the device that much. If you did it every day, then sure... but a few flashes over the life of the phone won't make much difference. I recommend you just do the updates yourself with these files and don't worry about the OTAs, because you are unlikely to get them.

Question Can I flash a US-based firmware on my s21 ultra while in Kenya(East Africa) SM-G998U? NB: everything else is fine just not receiving updates.

I have a recently purchased galaxy s21 ultra 5G SM-G998U and Im currently stuck on Sept 2022 patch with A12. CSC is XAA/XAA/XAA/ATT. I'm from Kenya and since this is a US-based model how do I go about accessing the updates, do I flash the firmware to the one in my region or the one in the US
Should be fine, as long as the CSC you want to use isn't included in the firmware you're flashing. You must flash the firmware that corresponds to your model number - meaning you can't flash G998B, G998W, or G998N firmware.
You'll need to use the CSC.tar, not HOME_CSC.tar, because you'll need a factory reset.
So I use a SM-G998U or U1 firmware?
