Verizon S8 with tmobile SIM - Cannot run system update

Neither on wifi nor cellular will it check for update. I get the error "sorry, we are having trouble authenticating your device"
Any idea how to fix this ?

wondering the same :/ anyone have anything?

see my post here. besides flashing the t-mobile ummm rom I guess over it, you won't be able to update. I've tried samsung and t-mobile and the only thing that will work besides that is to borrow a sim from a friend and use that... https://forum.xda-developers.com/galaxy-s8/help/best-buy-screw-t3594359/page2

try it today. it should work. the servers were having issues last night and this morning.

will not work because system updates are coming from carrier and having a tmobile sim in a verizon phone means verizon will not allow you to connect to their update server...

Thats not the case. I am using vzw GS8 on att and I receive updates fine

Well I'm confused then. I was able to do the last update with a t-mobile Sim in the phone? Right now when I try checking for updates it errors out saying it couldn't be authenticated. Anyone have any clue?

Hope I can help you!
How to update your system if you're not using the carrier from your S8(+) version.

you wont be able to updated through wifi or LTE unless you use a verizon SIM but you can do it easily using your computer and samsung smart switch.

Try to get at least an inactivated Verizon sim card from any Verizon store or you can also try a normal working Verizon sim. I had AT&T Galaxy S5 and it needed the carrier's sim card to even check for update. I took the sim, put it in, checked for update and was able to install it.

Fix to your issue
Hey guys so I do also share the same situation, I have a Verizon s8+ yet I have T-Mobile One as my coverage
Because it's not authenticated as a Verizon provided account it simply won't update
Now.. the solution to updating isn't directly on your device.
It's within the Samsung Smart switch App for either Mac or windows, you can run an update through there with little to no problems at all and finally keep your device up to date without having to return it for an unlocked one.
Just a brief note regarding the smart switch App, keep in mind that sometimes the update will freeze at a certain percentage on the computer so just be sure to close the app out only if your Samsung device hasn't received the green upload screen yet.
Hopefully this helps out alot of you guys ?
Best regards

I'd like to flash mine to t mobile, I'm begging you to help me with this!!!
Sent from my SM-G955U using Tapatalk

I've seen a bunch of info on the forums on how to flash the T-Mo ROM on an s8 - as well as flashing the Samsung Unlocked ROM on the s8 but frankly, almost all the threads are from back at the phone launch - and it is unclear to me which roms & programs to search for.
In a similar vein - I'm a noob to the whole process using oden - which I think is what i would need to use. I have experience from years ago running cyanogen mods on a nook tablet and messing with windows phones - but nothing recent and things have changed a lot.
I've read conflicting reports throughout the forums on doing this...
I'm running a VZW Branded (but it's now "unlocked")
Model: s8 SM-G-950U
Build #: NRD90M.G950USQS2BQL1
Baseband #: G950USQS2BQL1
What I'm looking for (really the right word is "NEED"):
Access to lower 700 A block (full band 12 use)
Ability to get OTA Updates
Mobile Hotspot Functionality
WiFi Calling
VoLTE
Bixby
If I could have these all running the Samsung Unlocked ROM - then that would be preferred...
If not - I would want to flash the T-Mobile ROM.
I need to know ASAP as I only have 14days from today (2/14/18) to figure this out or go back to VZW
Many thanks!

Update LG G6 AT&T H871 to Android 8

Hi everyone! i have a LG H871 ATT&T unlocked, I am living outside the US and I want to update the OS, it's running Android 7, But when i click update now it's says the Current software is up to date. the device is unlocked, what I can do?
LG Bridge doesn't work. It says it cant check my software version.
Anyone here have a solution?
Thank you in advance!

I've spent hours researching this and have only found one solution. You have to buy an ATT go phone prepaid SIM card for $2 and install it. Get a "Pay by the minute" plan (it won't let you checkout without selecting the plan, but you don't have to use it).
Once you get the SIM, don't activate it. You can simply install it and then check for updates over wifi. The G6 makes you wait 24 hours between each time you check for updates. You can either just wait until the next day or set system clock to a later date manually.
I've done this twice now to keep it updated. It's embarrassing that in 2018 LG can't push their own OTA updates.

Thank you very much for sharing your knowledge and experience. I've been in the same situation and not had a chance to test this, so I'm sticking to original Nougat. I'll order ATT sim card and try.

Awesome thanks for the advice! Question, do you live outside the US? I'm wondering if this will work for people outside the US.

So I ordered a free SIM card from AT&T and tried the changing the date trick to trigger an update and SUCCESS it detected an update! Unfortunately though that's as far as I get.
Once the download is complete it goes through the whole Android is updating thing, reboots, but still shows as running Android 7 and that there is an update pending. If you attempt it again it seems like it has to download it all over again.
Has anyone else experienced something similar?

Work outside AT&T coverage?

Does this method work If I am not from USA so No AT&T coverage?

I tried the trick ordered a the Sim and popped it in went to update found no update so assuming I actually have to purchase the cheapest plan to get on their Network even tried putting in the go Daily plan or whatever it was still didn't work said it wasn't available in my area and I'm in Los Angeles lol doesn't make any sense.

Hi, the best way to update to oreo is to use Hyelton'shttps://forum.xda-developers.com/att-g6/how-to/convert-upgrade-att-g6-to-h873-oreo-t3791848 method to convert it to either LG G6 H873 or LG G6 US997 oreo without bloatwares.
(Bloatwares are carrier applications that you cant normally just uninstall). That's what I did and am enjoying it, though without root because I don't think rooting this phone is currently possible.

If I convert to H873 or US997, does that mean the entire phone is recognized as an H873 or US997 model? Can I update Android Pie through it? (Since I know for a fact that it is released via OTA for H873)

You can update to pie but not over the air(OTA)
You can use the LGup app to update when you download the update.

Verizon phone shows "Sprint" as provider?

Hi, I have Verizon and after updating to Android 10 today (official Verizon OTA update), when I check the SIM status it will sometimes say "Sprint". It'll also sometimes say "Sprint" when I swipe down from top and look in upper right hand corner. Has anyone seen this? Any idea why? SIM card came from Verizon when I switched over from Sprint to VzW a number of months ago.
Thanks.

When you switched to Verizon, were you still just accepting OTAs? It kinda sounds like you still getting Sprint OTAs.
I bought a used Sprint phone, then fastboot flashed the Essential image, which prompts for the Essential OTA.

Same. When I look up Mobile network in settings it shows Verizon, but when I look from pulldown notification, it says Sprint. Tried network reset and no change.

I was just accepting OTAs. But the SIM is a Verizon SIM? Also, it seems like I have data and can make calls... how is that possible? I've gotten OTAs before (Android Pie) and didn't have this issue.

Do you feel that you're actually using the Sprint network? I can't see hotspot toggle anymore in Settings, I can't see a way to navigate there.

I'm the same but I feel I'm on Verizon network and not Sprint. APN says Sprint though. As long as I use Verizon Messages app, MMS/SMS work fine though. 4G and calls work fine.

If you (y'all) go to the APN settings (settings -> Network & Internet -> Mobile Network -> Advanced -> Access Point Names), are they Verizon? Have you looked up the Verizon APNs and compared to what you have?

I'm having the same exact issue. Before update, all APNs were Verizon. Post update, they'll be Verizon at first then randomly change to being all of Sprint's... How weird.
Mobile Network says Verizon, APNs say Sprint, SIM status says Sprint, and Sprint's OMADM updates setting appears under about phone as well. For some reason, the phone states its brand as Sprint too, even though the device is unlocked.

When the phone was switched off of Sprint's network into Verizon's, was the firmware switched from the Sprint dedicated releases to the Essential generic release? Basically you'd have to fastboot flashed a factory image downloaded from Essential's developer page.
I'm not saying this definitely fixes the problem, but the Sprint phones have firmware specific to them.

This one was never on Sprint's network. Maybe mine just got the wrong Android 10 OTA pushed to it then? I'm assuming a factory reset will probably be my only hope then.

No, I doubt that the wrong releases got pushed. It dawns on me that I haven't been seeing separate images on Essential for the Sprint, and everyone else for at least a year. Maybe they merged the releases and something in the build prop is whacked.

No [emoji854] it's my daily driver, rooted with a few mods. I typically wait until the release after a major version upgrade to do the upgrade. That gives me time to see if there are problems that will affect my use case.

That's what I typically do too. I saw that this was the second one for 10 put out, so I figured I was all good. Especially since the subreddit had been positive all of yesterday about it. I'm now wishing I could revert back without losing my settings, non-play store apps, and data.

It is? I could've sworn I had one pop-up before this one and this one was being billed as a "hotfix" for service issues from the first "stable" release. Oh well, guess I get Sprint service speeds for a month.

Also having same issue
Hi, all. I'm so happy I found this thread. I have an Essential that was purchased from Sprint and unlocked immediately in November of 2017. It has worked almost flawlessly since on Verizon (lousy battery life some months and some odd camera stuff going on here and there).
I have always taken the OTA updates and never had an issues. I took the Android 10 update as soon as it showed available in September. A few days later my phone was showing "roaming". I reset it a few times, pulled the SIM, etc. and got it working again but the SIM continued to show Sprint. A few more restarts and it showed Verizon.
This kept happening every few days. A few restarts and it was back on Verizon. I even had the Verizon store put a new SIM in when restarts weren't fixing it.
Now I am stuck in Sprint mode for several weeks and cannot get it back on Verizon.
The issue is you cannot send/receive MMS when in Sprint mode AND I cannot receive voicemails.
I am no longer up for flashing firmware, etc. I got that out of my system years ago and just want phones that work and don't cost a fortune. I'm hoping I can recover this thing without major surgery, because my old Moto G4 is a really bad phone at this stage in its life. I finally switched last week when my wife got mad that I wasn't responding to her MMS messages. First time I plugged the Moto into my car, Android Auto nearly killed it! LOL
Is there a fix for this? I can't live without MMS (or rather, my colleagues and family can't) so I may have to buy a Pixel soon.
Thanks!

Look up the correct APNs for Verizon and create the correct ones. Once they work, delete the sprint ones.
Edit:
I know you said your over the days of flashing, but I think I would sideload the first A10 OTA from Essential's Developer's site. You can do that in stock recovery, just using ADB.
Hopefully that will get you off the Sprint software. It's what I did back when I got a sprint version (used). I always start with the first release of the current version on the device. Often the first major release has specific stuff that doesn't get passed on in future updates. Or, that may just show how old school I am [emoji4]

Upgrade ATT LG G6 to pie

I bought a used ATT LG G6 on Ebay to replace the LG G6 my husband is using. The only thing is, it's still on android 7, Nougat. My husband's current LG G6 is on Pie, and I would like to upgrade the new one to that, but OTA update says it is current and no update available. I tried to use LG Bridge and it says it can't check the software version. I found some instructions to use LG UP but it was something about using CDMA software and I know that won't work. I haven't found anything yet for GSM, so maybe I'm not looking in the right place. I'm hoping someone here can point me in the right direction. I guess we could leave it on nougat but there's some apps he uses that won't work on that software. I'm also leery about it being unsafe without some newer security patches.
TIA for anyone who can help me.

To get the update, you need an active att sim, borrow one, then update. If it tells you to wait 24hrs or something like that, then change the date forward in the settings.

I finally Android 13 today update came over night.

I got it last night. It killed my mobile data. Wi-fi works fine but not mobile. I've checked the APN settings, I've reset the network options, I've even done a full factory reset. Nothing works.
Why? I think it's because I carrier unlocked the sim and have been running on Verizon through StraightTalk. I think the update is preventing me from connecting to Verizon and there is nothing I can do about it. I also can't downgrade to Android 12. I'm trying to figure out what to do next. It looks like I may can use a tool to change over to the EU version which will then let me go back to 12 or possibly unlock the bootloader without waiting weeks on OnePlus to send me a code.

the Google Voice redirection still broken under OOS13 any variant

Anyone working on a custom recovery for 13 on T-Mobile OnePlus 8 yet?

Its may 2nd and the android 13 update isn't on my phone. are you all sure you're using T-Mobile?

Good deal. I didn't even know there was an Android update coming, I had a notification and figured it was a security update. I installed it and was pleasantly surprised.

Were you able to resolve this? My device was fine on OOS13.0 but had the same issue on OOS13.1.
Fed up with OnePlus and T-Mobile and their shenanigans.

The sim card would be what connects you to the mobile network for any given carrier. Try pulling it and reinserting it. Maybe after a reboot. See if you have options under sim card, mine are greyed out but I think some carriers have more than one option under sim.

I did finally get it to work. I had to call straight talk and work with the support staff. They changed my apn and did some other behind the scenes changes that got it to work.
