Hi,
I bought a LG G3 from Ebay which was blocked on AT&T for using it both in the USA and in Europe (I choose this model for its frequencies supported). It is a D850 model as you can expect.
After receiving it, I unlocked it to run different carriers. I rooted it as well.
I want to install the AT&T 5.0.1 update from OTA (I don't care about root right know). But I have one big problem. I keeps saying that my software is up to date which is wrong. Is it because I'm on T-Mobile right know and AT&T blocks the update ?!
I'm using build D85010d. right know and I never had a software update notification. I've tried to set my phone date to a couple days forward as suggested by Android Police. No luck.
I just want to have the update. After that if it says "you are rooted, you can't install", I will unroot it and reinstall.
Is there any way to update manually ? I heard it's impossible thanks to AT&T.
This is beginning to irritate me.
Thank you in advance

have you found any solutions to this? i'm using an unlocked att G3 as well (although not blocked) and I can't figure out how to update. i even tried to put someone's ATT sim in it and it still said it was up to date, which is completely false. god i hate att. can't update, can't use Qi charging, can't do anything.
I can't update my lg g3(d855) too. It's have the 4.4.2 kitkat and i want upgrade it to 5.0.1 lollipop.
Plzz help if u find a solution to this problem
Same issue .......how to update to lollipop manually ....................... if someone can help it will be appreciated :good:
I am having an issue with the AT&T Lollipop update, as well. I bought a D850 from eBay on KitKat 4.4.2, and when I inserted my AT&T MVNO SIM and checked for updates, it found the Lollipop update. It started downloading, but about 2/3 of the way through, the display shut off (I had it set for 15 minutes). When I got the display back, this action had stopped the download, and it did not continue. Now, when I check for updates, it just says I have the current version. I have run system resets, and tried a different AT&T SIM, but I can't get the Lollipop download again. Does the start of a FOTA download set a flag somewhere that prevents re-downloading?
Only thing I could think of is asking for a .kdz file for your phone and carrier and then flashing that using the LG Flash Tool
unable to update D850
I have the same issue. I have a D850 AT&T version and my is not showing any update available. I am in 4.4.2. Any solution how to update? Please help. Thanks to all
I'm another victim of this. Have someone found a solution? I'm desperated. And sad, I feel scammed.

Hi, I'm New in the XDA forum.
My name is Neeraj
And when I saw your post, I found me.
What ever you do please don't do custom rom update.i found that in a hard way.
Like you I too bought one from ebay, at&t logo but unlocked, and while trying to update says it's up to date.
Later I found out I need at&t SIM to update the phone. Because it's only network unlocked not the entire phone. It still got some sorts of at&t restrictions.
Any way I went and rooted, installed twrp, and cm13 6.0.1 then Walla my phone goes into reboot loop and when it finally opens up the network doesn't work.
By the I'm in Australia , temporary residence and I don't have at&t SIM.
So good luck and infact i'm hoping some one will guide me too
I fixed it, don't know exactly if it will work on others.
But what exactly I did was search Google download official stock rom for at&t LG G3 D 850 ( KitKat or lollipop), flash the rom and Walla got my IMEI number restored and it fixed my boot loop problem.
Then backed up by all data, IMEI, etc and then flashes back to custom CM marshmallow. Now all is well. ?
Hope it this will help some one aleast a newbie lie me
Hey everyone.
I'm running on completely Stock 5.1.1 OK1 on my Note 4 and just recieved the official MM OTA update last night. Due to my phone having a lot of junk and being laggy I decided to flash the official firmware from any external method to have a clean install of the os. I heard about Samsung Kies which makes a back up of your phone and installs the latest os, I installed and backed up my phone last night but it didn't seem to give me an update on the os, it said "This is the latest version" (5.1.1 COK1).
My main concern about this is. I've bought this phone from Pakistan (used phone but in brand new condition) and I'm currently living in Malaysia and I have no idea who was the previous owner of this phone. In Kies it shows the phone number different than what I have (maybe its the Sprint phone number?).
What if my carrier is locked by having a clean install? Or any sort of other related issue occurs.
Please take some time to enlighten the facts from your knowledge, will highly appreciate it.
Regards.
waiting for official release bro. If rom is released on sammobile, see the icon kies highlighted on the right.

Yeah but you totally missed my question here.
Its not that I don't want to do some research myself, I'm a student and I'm busy most of the time. So if anyone can take out their precious time to answer my question I'd really appreciate the help.
If you're concerned about your phone or sim getting lock..you can just use galaxy tools apk v3.1.5 & then upgrade the apk to v3.1.8 & it will unlocked it for you... but i doubt it will lock you down... maybe you can just try to back your rom completely & restore if any issues encounter
it's dependent on the way that they unlocked the phone, someone in vietnam has been locked after updated the phone, but my phone was not.

And I have no idea how my phone was unlocked, I just bought it like this. I can see the Sprint phone number on Samsung Kies maybe I should write an email to Sprint asking them to unlock it using that Sprint phone number?
I've got a friend who purchased an unlocked Note4 with ATT branding and software. She uses it on Tmobile. I noticed recently while googling that it looks like currently note4 on ATT is on marshmallow. However, when i try updating the phone it says its already up to date. The phone is currently on 5.1.1. Not sure why it's not updating. Could it be because it's on Tmobile as the carrier since its an ATT branded phone? How would I go about updating it?

I was in the same situation, and discovered an XDA thread that allowed me how to update my note4.
It's as simple as downloading the official at&t updates onto your sdcard and apply onto your phone.
It's a long thread, but well worth the read:

I really appreciate the hint. i just recently got a new note4 (obvioulsy im not in the U.S) and cant get updates like you. Im very new to samsung (mod,flashed the shaiza out of my m8 and nexus 7, but this is new territory)
when i saw the link you shared it has the following
EPH5 to EPH7.
DOI9-to-EPH5
DOI7 to EPH5
DOI6-to-EPH5
i dont see DOI2.
can you please help me out with a few more hints as to what you did to get the latest update available... (i know about placing the files on sd and bootlader, select update etc)
but do i have to manually install every update to reach the last one?

I performed every step one-at-a-time.
Another option is to utilize ODIN (software) to jump steps, but it requires windows.
I don't do windows
Remove the back cover (so the phone doesn't overheat), and take your time...it will take a while

Another way to update AT&T devices on that aren't on AT&T is to get an AT&T SIM (99ยข on the AT&T GoPhone site), activate it on GoPhone but don't add any funds. The unfunded SIM won't let you make calls, send texts or use AT&T data but it will let you get OTA updates on WiFi.
Dear all,
This is my first post and I have bought a honor 7x on ebay and I noticed after a few months that I cannot update the phone as there is no system update button. I contacted the seller but ofcourse he was not of any help.
From what I understood( correct me if i'm wrong), the seller installed a custom firmware on the phone so that there is no chinese on the phone. but with these custom firmware, there is no updates. I also get a message upon restart( please find the picture below)
I would like to update the phone . is it possible to update the phone or roll back to stock firmware so I can be notified of updates.
Please find the necessary attachment. Please let me know what I can do as I cannot access my mobile network section( hence cannot switch on roaming) .
i live in Europe and use english as phone language.

ok so you get the warning message, so bootloader is unlocked. Means you should be able to modify it.
your model is "BND-AL10" your region is "C00"
there are many full roms available for this model.
http://pro-teammt.ru/firmware-database/?firmware_model=bnd-al10c00&firmware_page=0
you should be able to install almost any of them through the firmware finder app search play store--- if you have google play installed
you should be able to install almost any of them through the firmware finder app search play store--- if you have google play installed[/QUOTE]
Thank you for your quick response.
I install the firmware finder on the play store but I couldn't trigger the update as there is no update button on the settings system.
Even though I do not have the update option in my settings, I can follow instructions to update the phone manually through the computer. If i understood correctly, I can follow these instruction: appuals.com/manually-update-honor-7x-al-10-firmware/
Is it possible to install another firmware on the phone so that I have the update option and also the mobile network section( hence cannot switch on roaming). I travel a lot and the data roaming is important for me.
I am completely new to this as I was an apple user, hence still discovering android possibilities

don't get a bad idea of android based on this device. It has way more specific weirdness about it than any other android I have had.
There is way to change to other area firmware, but do not try that yet. Your device is missing stuff , probably because previous owner deleted it, not because to version it is.
download fullOTA files for your devices listed model/ region and use HWOTA to install.

Hello, I did the update via the HiSuite of Huawei. I got the notifications on the windows programs. I did 2 update ( one for the system and the other one was the emui)
Now I cannot open google play or any google applications(maps, gmail, etc)
do you know how I can remedy that?
My emui version is 8.0.0
android version 8.0.0
It is a bit frustrating
my google play version is Google Play Store 10.8.32-all [0] [PR] 205344279 (240-480dpi) (Android 4.1+) 5 WHICH I updated through the Hisuite Update and downloaded this apk.
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 ?

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.

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.
