T-Mobile OP6T on AT&T - OnePlus 6T Questions & Answers

I'm finding a lot of the T-Mobile variant of this device for sale when I do a search. My question is it locked to T-Mobile or can I use it on AT&T
Edit: disregard I found my answer ?

Last week, I bought a oneplus 6t dual sim version from Amazon, the seller said that this is factory unlocked version, but I realized last Saturday that it is converted from T-mo to international one and it brought up the gpay issue and the same IMEI number for two SIMs. So, I contacted to the seller, and refunding process started, but at this moment, I am a little bit hesitated to do that because actual operations what I want are ok. so, I have to keep a little bit more and then I will make a decision, but no issues to use the phone on AT&T network. I am an AT&T pre-paid user. And automatically the VoLTE is active and call, text, and data are ok. Netflix , MaDonald are OK. Just Gpay got face the issue many people have faced now

ah. at first, the device had 9.0.11 version installed, so, I tried to upgrade to 10.3.9 directly through the 'local upgrade' menu, but failed.
so, I upgraded to 9.0.13 first and then local upgrade was ok to upgrade to 10.3.9 directly without any issue. And 10.3.9 installed successfully, the OTA to 10.3.10 is appeared on the screen, and it also works well. so, now 10.3.10.

and even though the same IMEI for two SIM tray got showed, but the phone detects both SIMs and showed they are active.
So, it seems ok. so, because of this reason, I am now hesitated to return this.

Yesterday, I moved to 8G/256G unlocked dual-sim version with different IMEI number and confirmed that the gpay works well under OSS10.3.10

Yesterday, I moved to 8G/256G unlocked dual-sim version with different IMEI number and confirmed that the gpay works well under OSS10.3.10

I have a done the change to International from emob and have dual sim, one number, is it safe to use both sims?

QJ3 updated bootloader

QJ3 <stock sprint> updated the bootloader from v4 to v5. Just a heads up for those of you wanting to flash the U firmware and getting errors.
So, probably a dumb question, but what do I need to do to avoid the errors? I messed up trying to flash a T-Mobile rom right after updating the firmware, and now I can't boot. I can get to download mode, but can't find a firmware that will flash without failing.
From what reading I've done, I need to find a newer firmware than the one that was on my phone originally, but I can't seem to find anything that will work.

You should be able to flash QJ3 or maybe the latest tmob one. Check sammobile or updato... Just checked, not posted yet. Have you tried a Google search for the qj3 firmware?

Thank you, I wasn't sure what the latest version is so that helps. I did try flashing the latest T-Mo and Sprint firmwares on both Sammobile and updato.com, but it looks like neither are newer than QJ3 so I guess that's my problem. I'll just search or wait to find a new version posted. This phone isn't a daily driver so it's not critical right now.

I had the same issue and just loaded the latest PIT. It allowed me to start my phone with my old Sprint OS.
Here is a version of the QJ3 zip for odin.

Thanks so much, this worked perfectly.
Has anyone tried going to the u firmware via pit file? I remember this working in the past. You have to flash the version pit file and previous stock rom, then you could flash the u rom.
Is there any way to downgrade bootloader from P version and then install U version?

Maybe. About a year ago, you could load a PIT file. Not sure if that method works with the newest bootloader. @spamforme mentioned something about it a few posts ago.

Right now there is no way to downgrade to install the U version software. Sprint upgraded to the version 5 bootloader and is the only carrier in the US to do so, so you can't install any other carrier software on your S7 or S7 Edge right now once you have Sprint software installed on it. I have a SM-G930U I took to sprint this past July under the 1 year free service before taxes promotion. Fully unlocked version I purchased online, after having trouble installing a Sprint sim, I had to go in to the store to get the phone to activate.
Once activated Sprint sim locked my unlocked phone(found this out 2 months later when I tried to put another sim in it.) At this point it was still running the SM-G930U Unlocked firmware. I escalated a sim unlock request in September, 2 months pasted and they still didn't unlock my phone. I ended up having to go back in to a Sprint Store to facilitate the unlock, and during that process the Sprint store, flashed my phone to 5BQJ3, that being said, after they did that to unlock my phone they were unable to put the Unlocked firmware back on the phone in the store, I have failed to put the unlocked firmware back on my phone since also, I have escalated this to Samsung, as my phone is under warranty and Samsung say there is nothing they can do. So Sprint sim locked my unlocked phone, and during the process of getting my sim unlocked phone back unlocked, they hijacked my phones software and put all the sprint bloatware and malware on my S7 SM-G930U unlocked phone, and it can't be removed currently as Sprint is the only carrier using bootloader 5 in the US.
I ended up filling out a complaint with the FCC about this last week, and waiting for Sprint to respond as the FCC filed the complaint with Sprint on December 22, 2017. and they have 30 days to respond. But I have tried everything I can think of to get the phone back to the U version software without any resolve. As far as I am concerned Sprint owes me a replacement Samsung Galaxy S7 Unlocked phone or newer model, and right now the only "Unlocked" variant Samsung phone Sprint even stocks is the new S8 Active SM-G892U phone which is the same phone for Sprint as it is for T-Mobile; but we shall see what happens I am not holding my breath with Sprint and will probably just have to take them to small claims court for the replacement cost of my phone as it is cheaper than submitting a formal grievance with the FCC is the informal one doesn't solve the issue.
is there any other carrier firmware with the same bootloader version that i can flash to? i need a phone for Verizon, i'm stuck on the sprint firmware. there's a band that is disabled on the sprint one. hopefully one of the others, if there is one available, will have the bands needed enabled.

Wow - nice persistence following up with FCC! Would love to hear how that gets resolved. I'm also stuck with a 930P v5 bootloader and no way to install 930U firmware. What is the best way to track 930U firmware bootloader versions so that I know if/when v5 is released?

G930UUES4BQL1 is bootloader 4.
G930UUEU2APG9 is bootloader 2.
G930PVPU5BQJ3 is bootloader 5.
At the end, go 5 digits back and you will get the boot binary version. So when the U firmware gets to G930UXXX5XXXX it should be good to go. Based on the U history, it looks like the bootloader will get updated if/when oreo gets dropped to the device. It seems like they went with 2 for MM; 4 for Nougat; and hopefully 5 for Oreo. Every carrier seems to be updating the bootloader version about 5 months before the actual release of the new OS...maybe that means that Sprint will be the first to receive Oreo.

Thanks so much for the great info!
If we wait for oreo and it has bootloader 5 then it will be great assuming we do not update the sprint oreo first potentially changing the bootloader version number again. Would be great but I guess now we will just wait and see

Bought H918, imei says it's H990 (Isr Israel). clear on swappa help

I bought this supposedly T-Mobile H918 on ebay. It says it works with T-mobile, Lycamobile, UltraMobile, Simplemobile. I figured (assumed (mistake)) the phone was unlocked. Tried to use a Freedompop gsm sim, no go. Went over to T-mobile they said it was NOT in database, couldn't unlock a phone not in database.but rep put his Tmobile sim in and it worked. I decided to order a T-mobile sim online for $10. In the meantime I went online looking for a LG IMEI checker. It turns out the phone is an Israeli H990. I guess someone flashed the T-mobile H918 on it. The IMEi is clear according to swappa and others. Should I send it back? It had H918 10K on it and I flashed back to 10J and rooted. I like the phone, but is it possible that it could get blocked down the line? If it's clear and can be used on different T-mobile MVNOs is it unlocked? I plugged IMEI into AT&T checker and it said something like, it's clear, we just need to get the right sim. Any help or info or ideas appreciated, Thanks Johnm

If you were able to root it, then its probably a database mismatch. The gsm simcards usually pose problem to T-Mobile's android handsets due to UICC activation (or UICC unlocking).
A crossflashed phone is hardbricked the moment u unlock its bootloader and load a custom recovery on it. (Had my chinese fake G3/G2 moments back in the days). Your phone is fine if you rooted it and its working right out of the box.
Two things that dont work if u modify the system of LG phones is RIL and the abnormal screen behavior. For your case, both work. I'm from Pakistan but I often end up having unlocked phones from American carriers. Right now I have Samsung Tab A which is from T-Mobile and UICC activation doesnt make my LTE Sim work on it. With T-Mobile its kinda common to end up into an "invalid sim card" error when u try to use a non-T variant.

Oreo update on unlocked ATT S8 with T-Mobile sim

I have an unlocked S8 and I have not got the Oreo update Every time I go to check, it says your software is up to date. Is it because I am using a T-Mobile SIM? If yes, do I need to use ATT sim to get the update?

Yes you need an AT&T sim. Otherwise you will not receive ota updates.
Try it now
When I unlocked my AT&T S8, and stuck in a MetroPCS Sim, MetroPCS updated the phone to Oreo. This also results in the boot logo changing to MetroPCS which I think is unfortunate. And it installed a couple of Metro PCS apps including the voicemail app. This was all interesting since this means a carrier will update an OS on a phone that was originally sold for a different carrier. Seems that could run into problems but maybe not.
Did you figure it out?

I have an AT&T unlocked S8 Active with a t-mobile sim. I tried using an old AT&T sim with no plan, but it did not work. Do I need a sim with a plan to do the stupid update?
Take it to a Samsung Experience in a Large Best Buy and get them to Update it.

Is there any way to manually update it to the latest version? Caz I am stuck on Android 7.0 as well, it won't update.

Pixel 2 128 gb Verizon warranty replacement - current patch bootloader unlockable

I recently received a pixel 2 128gb factory refurb from verizon as a warranty replacement. After searching around and seeing this thread I decided to check it out.
My enable bootloader unlock was able to be toggled in dev options, I followed instructions and the bootloader is now unlocked.
My device was updated and on the april 5th patch.
I am not sure if the replacement is non-verizon, or what but I thought I would let you all know. The replacement was done through verizon via their paid warranty program.
Proof:
https://imgur.com/a/ou0w8uM
This replacement was for a broken HTC 10 - after a long talk with customer service. They originally wanted to give me an s7 but I wanted a phone with usbC and enough storage to match the 10s microsd slot.
I am new to the pixel 2 community, so I apologize if the 128gig verizon phone has always been unlockable.
pretty sure it was Google version.
did you turn it on with Verizon sim or did you unlock the BL first and then insert Verizon sim?

I turned it on without the verizon sim, in case the patch was one of the older versions, as I was researching while it was on the way. The patch was recent, and I've had the phone a few weeks with the verizon sim in before I tried this. I just figured until today that it couldn't be unlocked, since the phone came with the march patch already installed.
But yeah, the phone was booted and setup originally without the verizon sim installed.
The unlock was completed today, I've had the phone about three weeks and it was completed with the Verizon sim installed.

Bought "Unlocked" phone, has sprint branding, seller insists that's how Samsung works

Bought "Unlocked" phone, has sprint branding, seller insists that's how Samsung works
Hi everyone, I bought a Galaxy S10+SM-G975U (same model that all 4 major US networks use) that was sold as "Unlocked" without specifying that it is Sim unlocked, Network unlocked, or Factory unlocked. Most of the time unless a seller specifies which unlocked then it means the phone is Factory unlocked, I gathered this from 9 years of buying and selling Android devices so it's not just a guess.
When I got the phone Sprint OMADM pops up and tells me I have an incomplete activation, "about phone" told me it was Sprint Network Unlocked; after a week it now says unknown under "Brand" in the "status" section.
The seller said that when you buy a factory unlocked Samsung phone and put in a network sim card that Samsung then loads the branding (bloat in my opinion).
1. Is this true that Samsung could have loaded Sprint OMADM?
2. If true can I remove it so that I don't have to "Force Stop" it after each startup?
3. Is there any piece of software or database that I can look up the origin of this phone so that I can either change my eBay review of the sale and apologize for my mistake, or affirm that indeed the seller failed to disclose branding that he knew wouldn't go away when a buyer puts in an ATT simcard such as I have.
I've read one single thread by a user and not a Samsung official that claims that you can pop in a network sim card and then restart to change some software but I have not found even one more thread mentioning this phenomenon.
My background:
I've bought factory unlocked my Moto Pure X and a OnePlus 5 and neither did any ridiculous **** when I switched networks, so that's why I doubt this claim.
I bought a AT&T branded one for use on TMobile. It kept popping up errors. I flashed the unlocked firmware and it works great. I get unlocked updates and everything. You'll need to look on here but there's a walkthrough somewhere. But there are a few advantages for running the carrier branded version so you could flash the AT&T firmware instead. I wanted less bloat so I went with the unlocked one.
Think this might be the thread:
https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657
That said after I did all this I did read there was going to be a update to the firmware which would do what you described.... Switching firmware based on the sim card. Never seen it happen on mine still on unlocked unbranded firmware. Maybe this phone is running old firmware prior to the update that implemented this?
not normal. LIke you, I purchased an 'unlocked' phone and when I powered on, it was a Verizon phone. I popped in my TMo sim, and it worked OK, but I would get the annoying Verizon popups reminding me that I'm on on their network. I installed the unlocked firmware and it went away.
But there's more: when the phone had a problem, I sent it back to Samsung under warranty (still unlocked) and when it was returned, I just installed the original sim and powered on. Now it seems to be a TMo phone, and when I look at the phone's software version, it shows TMB/TMB/VZW. It's been receiving OTA updates and I've disabled bloatware, so I'm OK with it.
Just to be clear I'm not going to flash anything. I'll just turn around and sell it. I need a stable phone for work and I used to mess around with flashing different roms and while it was fun it was a frequent activity and I don't have time for all the annoying trouble this phone has been. Thanks everyone.
Flashing rom is different from flashing a stock firmware. In your case the only way to be completely off from the previous network you are getting the notification from is to flash a G975U1 or G975U stock firmware which is unbranded or your network branded respectively and you are good to go. I switched my yesterday and am okay ?. I will be happy to assist should you change your mind
