Hi there, new member with a first question.
I bought an S10+ (SM-G975U) online, unlocked, to be used mainly with AT&T when in US, and different carriers when traveling. IMEA check shows the phone was originally on Verizon carrier, but works fine with AT&T sim card. However, it's not receiving OTA software updates, and the security patches are way behind. When I try to force software updates, says it's already up to date. Seems like on unlocked phones, or switched carriers the updates don't happen. I tried booting the phone with a working Verizon sim card, still no updates. Online searches say that flashing the firmware is my best (or only) option. I downloaded Odin, but I still have a lot to learn and don't want to brick my phone. I'm not sure which firmware version to get. AT&T vs Verizon? U or U1 since it's unlocked? Do I flash all 5 files or just some of them?
Thanks.

Ok, so my question ha a few points here. I have been flashing roms for many years but never really though of this until recently as I now have an unlocked phone.
1. As my Sprint Note 5 is unlocked, can I flash say the Unlocked Version of software to the phone taking away carrier branding? I manage a store from another carrier and I hate that when I boot my phone it shows Sprint. I know it will not trip knox as long as it is Official Stock software.
2. If I do flash said Unlocked version software replacing Sprint software, will it change my connection at all? I have seen that flashing ATT software on a Verizon device did manage to improve ATT tower connection however I wonder if this is maybe a placebo effect as opposed to actually changing the bands and connections the device makes.
If you guys could help me out that would be great. :good:
Cheers
There is no unbranded firmware for the Sprint model because well, it is a exclusive model so even if you flash XAS instead of SPR firmware some or all apps will still appear. The only way to get rid of everything Sprint is via custom ROM= tripped KNOX. The SM-N920P cannot run another firmware.
Upgraded to Note 9, want to pass my Note 8 on to a T-Mobile user. I want a complete T-Mobile experience, so all T-Mobile bloat and settings are needed (VoLTE, Hotspot, etc...) . Note 8 currently has latest CRID OTA from ATT. Looking for help in determining the correct way to proceed. I am having AT&T carrier unlock the device, so I would make this change after confirmed unlock. Also, once this is finished, will the device receive T-Mobile OTA updates?
I have read through https://forum.xda-developers.com/galaxy-note-8/how-to/guide-sm-n950u-u1-t3685884 but am confused. I see lots of mention of combination files, CSC changing, etc... that seem overkill for what i'm looking for.
Are these the steps I need to take?
1) Download latest Odin compatible TMB Firmware (which is what version?)
2) Download Odin on PC
3) Factory reset Note 8
4) Flash TMB firmware
5) Insert TMB SIM card
6) Success?
Yes just download this file

Flash everything with Odin and you will have a full 100% T-Mobile Note8 with all carrier features working

I saw here that simply flashing a different carrier firmware will not actually change carriers?? Is that correct?

Someone in that thread said I would need to flash an unlocked U1 firmware and then the TMB firmware?
I am about to do this as well, switching from AT&T to T Mobile using my AT&T branded Note 8. I just wanted to confirm that it's as simple as downloading the latest Android Pie firmware for T Mobile and flash it to the AT&T branded phone? Any precaution like some other thread mentioned to flash the U1 (unlocked) firmware first then flash the T Mobile firmware?
Also, eventually, I will be giving this Note 8 to someone in China. At that point, is it better to flash the unlocked version of firmware or just leave the T Mobile firmware on it?
Thanks so much for your help.
Note: the phone is already unlocked.
I just wanted to let everyone know that I went and got T Mobile. After the new SIM card was inserted in my AT&T Note 8, after a reboot, it did something, a screen with a SIM car graphics and some moving dot. Then it rebooted itself again, and then T Mobile splash screen showed up. It even added the bloatware from T Mobile. So, Android 9 for Note 8 probably has both ROMs? I also checked the firmware version. It shows the latest T Mobile ROM.
I didn't have to do anything other than just inserting the new SIM card from T Mobile.
This is very interesting to me, and the store guy couldn't believe his eyes either.

And i was wondering why my phone still showing at&t bloatware even after installing the Verizon firmware. ? Now i understand Cuz I'm using at&t sim. Good to know?
Another update!
I just got updated by T-Mobile to the latest firmware after converting over as previously stated. I have to say that the update page on the phone for the T-Mobile firmware is MUCH nicer and informative than the ATT version. It tells you how much time left, the version numbers, and even a "what's new" section...
After this update, my phone is actually better at battery usage.
Can anyone tell me if there is newer software for this phone on AT&T?
Currently:
Model LM-G900UM
SW VERSION G900UM10e
Security June 1, 2020
I'm reading there is a version G out, but I'm not getting an update. I even tried a new SIM.
I have the Canadian version, same model and no we haven't had a software update here either
From my knowledge the only ones that have gotten an update are the international unlocked versions which are running the Snapdragon 845
At&t has had two security updates and they're not getting to me. No one at at&t seems to know what to do.
So, this saga has finally ended. My firmware was G900UM10e. VPN bug, and phone would not take OTA. It kept saying I had the latest firmware. To their credit, AT&T support DID try everything. The phone wouldn't even take a push from their servers. New SIM card, factory reset, nada.
So, they sent a warranty replacement with G900UM10n loaded. VPN works perfect. I NEED it for work. And, today I managed to get G900UM10o over the air.
Either the IMEI of my old phone was MAJORLY hard bricked on their update server, or there was a bug in 10e blocking OTA.
Anyhoo, just wanted to share.

I haven't tried the VPN, but I would like to update to Android 11, and I am still stuck with the June 1, 2020 security patch on android 10 with the software version of G900UM10e and my model number is LM-G900UM. I got mine from the USA but am currently living in South Africa, so is there any way that I can fix this issue?
Only if you have an AT&T Sim card. You can't do an OTA update unless it's on the AT&T network.
e is the variant I got stuck on. Since I got my warranty replacement, I've gotten numerous updates, including Android 11.

So basically, I can't ever receive updates unless I get an AT&T SIM card and are on their wireless network?

Correct.
Well, that sucks. Do you know of any way to bypass it, or is there a custom ROM that I can install on this variant of the LG Velvet?
I recently bought an unlocked AT&T Samsung S20 ULTRA 5G (SM-G988U), it doesn't get any OTA updates, I found out that I would need an AT&T sim card to do so but I'm not an US resident, so I can't get one.
Since AT&T doesn't publicly publish their firmware files and I want to update my phone, I was wondering if flashing my phone using another firmware with a different CSC code like USC (US cellular), would be risky or is it a safe procedure?
This would be my first time doing this procedure and that's the only part that really got me thinking.
Thanks!
U firmware is identical, no matter which carrier it's from. So if AT&T's latest release ends in UH2 and there is also a UH2 firmware from US Cellular, flashing it would be just like flashing the AT&T firmware, if it were available
Also have same question I have Samsung S20 . SM-G988U , service provider software version SAOMC_SM-G988U_OYN_ATT_RR_0018ATT/ATT/ATT Baseband Version G988USQS2SUE2, I am not able to get new updates as I am not in US, I need suggestion which firmware of android 12 I should update on my phone.
A question from a noob here. I have a T-Mobile S22 Ultra phone which is network unlocked. As I recently I switched from T-Mobile to Verizon, I'm missing some of the features that are Verizon specific, while not needing anything that is T-Mobile specific anymore. From what I understand, Samsung installs multi SCS firmware on most of the phones these days, which can be changed by a dialer code. That however did not work at all.
Another option I've come across is by flashing provider specific (in my case Verizon) firmware as long as firmware version is the same (S908USQU2AVDC). There are a number of articles on how to do it by using Odin. The issues is no matter what I do and what files I select (like by using CSC file instead of HOME_CSC with or without flashing USERDATA file as well) the result is the same. It shows success and reboots and then reports an error and does the full factory reset which ends up back on T-Mobile version.
The question I have if it's even possible? And if so what I'm doing wrong here. Unlocking a bootloader is not really an option for me...

In theory, flashing the correct firmware (VERIZON) should work. I would honestly first wipe the device, then flash (clean, not dirty) the Verizon firmware and setup accordingly. I had a similar case with a TMBILE unit (I had changed carriers) and I had managed to use XAA CSC and then when I reverted to TMOBILE SIM it would not "restart and install carrier updates". I had to basically switch the unit to U1 and then revert to U and it finally pulled all the TMO crap.
I may be mistaken since I haven't done this type stuff since S10, but I think you need to first reset the device and flash the unlocked version then when you put the verizon sim in it should provision it. Then you can flash the verizon package if you want the bloat apps. The features may be hit or miss. You may need to activate the features on the verizon website. Some features may never work as the carrier wont push them to IMEI not in their database of branded phones. There may be things you can do in hidden settings with "Activity Launcher" or other methods.
I'm here trying to figure out the same things for Tmobile and a factory Unlocked phone, before I buy.
Thanks a lot for your suggestions guys! I managed to do what I wanted. This is what I ended up doing, first flashed the unbranded U1 version on my phone and on the first boot Verizon sim was provisioned. Then I flashed Verizon firmware and it worked!
