How to switch to correct update tree (to get OTA updates)?

(Please don't ask me to search the forum--that isn't working right now, it just gives an error.)
Several months ago, I bought a Nexus 6 phone, used from eBay. I have been using it with an AT&T SIM card for several months. However, it is stuck on build MOB30I and patch level "May 1, 2016". I thought that AT&T was simply months behind on updates, but today I learned the real problem: AT&T uses the MMB update tree, whereas my phone is (for some reason) on the MOB update tree. Apparently:
- My phone will not accept AT&T's MMB updates because the phone is on a different update tree
- My phone will not accept MOB updates (from Project Fi or Sprint or whomever) because an AT&T SIM card has been installed.
I tried removing the AT&T SIM card and checking for an update, but got nothing.
How do I switch to an update tree that will actually give me updates? I'd rather not install adb and sideload. In fact, rather than do that, I would instead enroll in the Android Beta program, install Android 7.0 beta, and let Google itself update me to Android 7.0 final when the time comes.

Any reason not to use a Google Factory image? It looks like MMB29V is the most recent.

According to the instructions, installing a "Google Factory Image" would be a lot of risky work, and would erase all my data and apps. I was hoping for something simpler and safer. As I mentioned, joining the Android Beta program actually seems to be the easiest solution, if the current beta (NPD30G) is stable enough.
Frankly, I am surprised that Google/Motorola/AT&T (or any cell phone designer/manufacturer/carrier) allows a working cell phone to get into this state where the phone refuses to accept security updates.

For the Nexūs 6, the beta is quite stable (I didn't update my daily driver until I was sure it was stable on my other devices). You should be fine and back on track with NPD90G.

That's half the fun of owning a Nexus, not waiting for updates. Dl the factory image, unzip it and the zip file inside and flash the system. IMG only and you'll lose nothing but root. If, of course, you are rooted.

As already suggested, just install the system image. The simplest way to do that is via fastboot. Nothing gets erased unless you flash the userdata.img. Using Google's script to flash everything would overwrite the userdata partition.
The version you are on (MMB) is released to provide updates without updating the radio. The MOB release is the same as the equivalent MMB plus the package includes the updated radio. This is a requirement of the carriers who want to approve the radio before it's released.
You will be unable to take any *incremental* OTA if there is any differential between what's on your system partition and what the OTA is expecting. You can not hop over incremental OTA updates. They must be sequentially applied. Therefore, the safest way to get to a known state is with a factory image.
If fastbooting a factory image is unacceptably risky, then maybe an eBay phone wasn't a great choice.
Or, as you say, you go straight to N. If the beta program is still available now that N is released.

I decided to do this. NPD90G is running well enough for me, and before long Google will release Android 7.0 Final.

October OTA Update 4BQJ2 is out

Just got my OTA update notification. Update went smoothly (sorry, forgot to check file size before updating. Confirmed BlueBorne vulnerability is fixed.

Not sure if this is unique to me, but post-update, my phone is now telling me my SD card is unsupported and asking me if I want to format. Really hoping to avoid backing up a 200GB card, formatting and restoring this weekend. Not sure if anyone else is having this issue too or if just my luck to have to deal with, but just a warning out there to those who may decide they want to unmount their SD cards before updating.

FWIW, my device seems to be running just a bit smoother after a day of use. No noticeable change in battery life. Pleased with the update so far.

quick newbie question, I have the G935A , fully stocked, but using it on a Canadian network, I was told I won't get the update via OTA so I installed Smart Switch, but it also says my device is up to date which has the May security patch installed (that's what it came with when I bought it last month). Any idea where I can find just the OTA patch and update the phone ?

If you aren't running on an AT&T network, you might seriously consider switching to the U firmware. Of course, Samsung conveniently forgets the U firmware exists too, so that might not gain you a whole lot at the moment.

I have the U firmware and I've been checking for updates, but nothing (I'm on the August security patch). Is there a way to force the update or use Odin or side load it? My phone was originally built for the Sprint network, then the previous owner flashed it to work on AT&T. I was not able to get any updates (was stuck on the May security patch). I used Odin to put the U firmware on it and then got 3 security patch updates after that.

The U firmware always lags the carrier firmware. August is sadly the current date for the unlocked devices for now.

All I had to do was be patient. I got the newest update (4BQJ5 - November security patch) this morning.

No may update for Singapore model still?

Its been a month now and I haven't got any update I'm still on ASD5. If It's only me who haven't got the update then please let me know what to do now. I want to update without losing data via odin.and I haven't touched my bootloader or tried to root.

I believe even the latest update for May patch has been pulled out due to several issues reported.

I bought this phone today.. is iy possibly the reason to nog getting may update at all. I updated for the first time today

No, some regions never got the may update which has actually been fortunate. The may update has been withdrawn due to issues.
I'm in Australia and it didn't get released. https://www.gizmodo.com.au/2019/05/relax-samsungs-big-s10-bug-wont-affect-aussies/

I've already updated to ASE6 firmware.. Using samfirm download the OXM ASE6 firmware from any region which have this and extract the zip files.. Put the respective files using odin and use the home_csc to flash to phone.. You won't loose any data or files in your phone and will have the latest firmware...

Just wait like most everyone else does. It doesn't go out to everyone at the same time. It's not always best to be first.

It's quite sad but I know singapore is very slow at receiving samsung firmware updates...

Indonesia region still doesn't have it yet...

Samsung S10 AT&T (G973U) not getting updates since 1 August, 2019 Security Patch

Hey guys.
I bought my phone from AT&T retail shop in the US last year. But unfortunately I had to move back to my home country. Ever since the August 2019 Security Patch, I have yet to get any update. The AT&T website indicates that my phone is due to get an update in December 2019 but I have yet to get it.
Is there a way I can resolve this. Whenever I check for updates, it indicates that my phone is up to date. This happens also when I use Smart Switch application.
Samsung S10, Snapdragon 855
Model: G973U
Baseband Version: G973USQS2ASGK
Thanks in advance.

August? You are like 4 or 5 updates behind! Android 10 is out for the S10 now. You're probably going to have to flash the latest firmware using the patched version of Odin floating around the forum here.

Unfortunately since August. But thank you for this insight..I have been searching for days on what I should do. Though I would like to know when I do flash using Odin, will I start getting updates or do I need to update manually every time.
Also if there is any other way of solving this problem without having to flash my phone I am willing to give it a shot.

Flash whenever you want, but it will reset your phone unless CSC_home is used. You might get updates after flashing with Odin as long as your SIM card matches the firmware (i.e. T-mobile firmware and SIM), but then again you might be stuck using Odin to update every time.

N960FXXS8FUC4 april 2021 update ?

So guys I'm on android 10 one ui 2.0 the very first version of it dec 2019
And just decided to get the newer version of 2.0 the jan or feb patch but the ota update comes up with april 2021 update
N960FXXS8FUC4 this is I think 2.5 one ui the very latest version, do Samsung delete older updates off the sever now and just push the latest updates?I'm 17 updates behind I was expecting to be able to update 1 by 1
Instead of being forced to jump to the very latest version in 1 hit

Bump for help guys please help guys this forum Is dead i know due to the note 9 being old but i would really appreciate the help
Maybe I should remake this thread and put it into the s20 section because that forum is not dead?

I don't believe Samsung delete previous OTA updates from their servers.
OTA updates are incremental, in other words each update will apply changes from a specific previous version to update it to a specific newer version.
So for example a recent over the air (OTA) update would be for 8FUC4 to update to 8FUD1, this update would only be downloaded by your phone if it was on 8FUC4, also when the phone reboots to install the update it again checks that the current software is, in this example 8FUC4 and will only install the update if 8FUC4 is the currently installed software.
If you update automatically in this manner then it's one upgrade at a time I believe.
If you want to update in one jump to a particular firmware then you would need to manually download a specific "full firmware " from an independent website such as Sammobile, usually approximately 4Gb in size to your pc and then flash thus full firmware using ODIN software

My phone uk note 9 unlocked doesn't update each fw one at time like I would like ,im currently 17 updates behind and when I go to update via ota its skips all 16 updates and offer me to install the lastest version of android so Samsung must delete the old firmware from the fota servers
