Install T-Mobile software instead of international

Hi everyone. I purchased a OnePlus 8 5G directly from OnePlus, running on the T-Mobile network. After trying to figure out why I didn't receive the T-Mobile 5G SA update (10.5.17.IN55CB), I realized my phone is running the international version of the software. I guess this is because it's factory unlocked but I didn't realize this would limit my access to T-Mobile 5G updates! I never travel internationally and don't really care about an unlocked bootloader, etc. as long as the SIM is unlocked.
Can I manually download and install the T-Mobile software so I will get the 5G SA update (and future T-Mobile OTA updates)?

i was also wondering if that would make a difference. maybe someone could provide the modem.img from that update, if it changed. flashing the euro modem on the international rom definitely made a difference for me. not really with speed but overall coverage and stability.

Right now you dont want it. It breaks incoming and outgoing phone calls.

Seems they pulled the update as well

Guys I'm on TMO but switched over to global voluntarily. Honestly check out TMO 5G info and you'll find it's not as great as you think. It's the beginning of a software change. Veteran modders know the beginning of updates have a lot of bugs.
If you really want it then get the MSM Tool, downgrade to 10.5.7 and let it upgrade you manually to 10.5.17. then you can get back to global if you'd like with the modem. Happy modding!

Thanks, it sounds like it was premature. I live in a rural area and my main concerns are 1) better (not reliant on LTE) 600Mhz coverage and 2) lower latency.
Do you think the global software line will get an SA update down the road? Are there any other difference between the global and T-Mobile line of software that would affect my coverage performance with LTE or 5G?

Great question, This is my first OnePlus phone so I can't tell you if and when gonna will get the update. What I have heard of that TMO is rolling out 5G in several layers. This first one is pretty low key but it had some books already. Second and third would be better. I guess check around here to see more about it. If you are absolutely sure you want this update then you can use MSM took to downgrade then just let the TMO servers do the work for you. Happy modding!

I would be surprised if the global version got an update for SA 5g. That's TMO specific and OnePlus would have zero care about a specific carrier of all the world's carriers .
There are differences in modems according to TMobile. I can't remember specifics but I think it was carrier aggregation on band 66 ( I don't remember much so I may be way off)

Yeah, I figured that was unlikely with the global version, although I'm sure carriers across the world will begin deploying SA 5G at some point.
I was going to start a new thread but after you notes about the modem differences, this might relate to another issue I've noticed: When connected to Band 2 (1900 Mhz) with LTE or 5G, I was getting really good speeds (~30Mbps Down/5Mbps Up). Now, when I test using 5G or LTE (by turning off 5G) my speed tests are horrible: ~1Mbps Down/0.7Mbps Up. I have tested with "Smart 5G" on and off, and also removed and reinstalled the SIM card. If I pop the SIM card out and put it back into my Pixel 2, I get 30Mpbs Down/5Mpbs Up with LTE on Band 2. My Pixel 2 was purchased directly from Google and is factory unlocked/direct Google updates.
Do you think this is because of the carrier agg issue you mentioned? In my area Band 4/Band 66 is only used for T-Mobile 2G/3G, to my knowledge. LTE is offered on Bands 2, 12, and 71. 5G NR seems to only be on Band 71 here at present.

Josh, not often this happens, but I disagree with what you say here. Normally I agree with everything you post. However, this time I have to disagree.
5G SA is not at all T-Mo specific and is a standardized implementation for carriers should they choose to go that route.
However, OnePlus caring about it is up in the air, lulz!
See here: https://ibasis.com/what-is-5g-sa-nsa/
5G SA means stand alone. This means that the device will only ride on 5G and not aggregate with 4G.
If I am wrong please correct me. Thanks!

I and many others posted that they cannot get the update. Those that did said they had connectivity issues. I suspect that T-Mo pulled the update. I don't know this for fact, however I cannot get the update. T-Mo site says check back after 8/31. That's crazy weird. Others also complain. I think the update is borked hence the lack of wide roll out. . Again, dont know this for fact but just speculating...

For sure. I do stand corrected here on SA. I was referring to the specific bands that TMobile uses for SA 5g vs world bands SA 5g but who knows if that's impossible but I, like you, think that OP will not care about it or would screw it up.
As for the modem differences, I was referring to an older post from TMobile on their forums during the 6t launch days so I can't really remember exactly what it was. I think if you searched my posts from way you could find it
Speaking of, I am incredibly disappointed in tmos 5g. I'm lucky to get 20 dl. Are you having any better luck

Yeah I think you are right. As soon as it was available it became unavailable. They will roll it out when those bugs are fixed. This is one of the reasons I don't like TMO stock. They are buggy and slow to update. Not to mention all the bloatware.

History of my observations...
When I first switched to T-Mobile with the 6T the speeds were great. Well, decent. But around the time the S20 series came out I noticed extreme sluggishness with the 6T. Compared it to the people in the store and there's wer the same. A massive down turn in speed. I suspect it had something to do with the implementation of 5G in the area. It was my guess... Anways, moved back to T-Mobile two months ago and got this phone. The speeds are even worse. So this phone on 5G is just as bad as LTE. I disabled 5G and tested. Same results.
Long story short, T-mobile did something and slowed my connection down.
Your lucky. Very luck. I routinely get 2 to 5 mbs when I am home. In town I dont think I got over 25Mbs. AT&T has the best network in Fargo. 200MBS down on S20U all day!

Terrible data speeds.

Just got the OnePlus 8 5G for "Sprint".
I took the June security patch update and my cellular data has been garbage. See attached photos.
I can't be the only one experiencing this, right?
I've contacted Sprint and Tmo.
They had me reset all my connections (wifi, bluetooth, cellular) and they refreshed their end.
Still crap.
Any ideas?

Welcome to 5g with TMO. Also the new modem is garbage too to begin with. You could always flash the previous version modem or turn off 5g altogether.

So I'm trying to reply on the Gcam thread for OnePlus 8 and it keeps telling me "Post creation failed"
Why?

I actually got 120 something down peak and avg of 60 after the update. But, still, I was consistently getting 120+ on lte on my 7t. It's like when tmo sees a 5g phone on their network, they reduce lte speeds. But the new software is a definite improvement unless it's related to the additional 2.5 ghz 5g band
edit: The latency and ping is still terrible though . I should have just kept my 7t

Possibility of 5G for US being enabled?

I recall on other phones, notably the Nexus 4, that LTE could be enabled via a modded Kernel or Radio IMG(can't recall). What are the chances that this mod would be possible on the Nord as well? Has anyone already looked into it?

I've done zero modding to my device and have consistently gotten 5G on Google Fi in the US.

No, you likely haven't, it just SAYS 5g on the bar which I suspect is a bug.
If you actually run a network tool, you'll see you are only on Band4. The Nord doesn't have official support for the T-Mobile bands the US uses for 5G. I see the same thing and I'm on Mint which is just re-sold T-Mobile.

10.55.22.in55cb

do we have any information about this patch? I received this one from t-mobile(i have that variant) and having a couple of issues. it looks like it brought the september security update, but the play security is showing oct 2019 as the date and wont update. any information or is anyone having any new information?

They didn't say much in the changelog, but I know it has some radio fixes for 5G and Sprint's network.

I'm on global rom. Wonder if there will be a push for modem on global using tmo sprint sim

I had the same thing happen to me. I am sim and bl unlocked, but I get the message there's an update, but it fails everytime. I've reset my phone twice in the past 2 days but it has yet to come back. Any advice would be much appreciated.
Edit: I'm on an t-mo 2017 10.5.20IN55CB

I would recommend switching to global firmware.

I would as well. But Global Firmware is missing 5G SA I'm pretty sure unless something has changed recently. Its nice to have as its easy to force 5G only in areas where it may be fringe. Which for me results in either 2mbps LTE or 60mbps 5G...

Correct. I've tried both and I had trouble with Tmobile 5g on Global firmware. Also I didn't like the android 11 bugs and TWRP not working. I'm happy for now running 10.5.22 rooted.
As far as the issue people are having, I wonder if 10.5.22 got pulled? It's still not on the Tmobile update page.

I've not had any issues with A11 on tmo. 5g with global rom.
What a11 bugs are you referring to?

Question Whats the best Variant for US

Whats the best OTA to install using the OnePlus 9 in America?
Im on the LE2110DA version. Is that as good as its gonna get? Running Omega Kernal?

Check your telegram

Question is so which OTA is Tmobile if I wanna use that. Because my Google FI runs on Tmobile. Misewell try that variant right?

If you read up youll see lol.
LE2110 DA 11.2.8.8
Also using the wonderful Omega Kernal.

Forgive my knowledge but which variant is le2110DA? If its oneplus 9 5g, omega kernel works? I thought omega kernel js only for the pro variant.

Best one for North America would be the LE2115. LE2110 is the China variant which is missing some 4G/5G bands used in NA.

I got 5G, im just wondering if the OTA versions make a difference.
Yes its the Unlocked Chinese Version. LE2110.
So is there a difference between AA, BA and DA as far a cell quality?

Software doesn't give you access to additional bands. You might have SA41 (tmo) but more likely you are just on b2/66 and tmo just gives you the 5G icon. Check with cellmapper to be sure. Your best bet is to get rid of the 2110 and get an actual US device if you want proper 5g

I was thinking the same thing about the 5G icon. It goes from LTE to 5G sometimes.
My speeds are about 50-60mbps when im not connected to wifi. You guys think thats pretty fair and decent?

avid_droid said:
For me, Tmo has had the least of issues. No data or calling issues. No Bluetooth issues such as robot voices on car stereo and better distance outside of vehicle. No odd hiccups.
Although people are mislead with T-Mobiles update numbers not matching,they're actually the same. 11.2.8.8 for AA,DA,BA will be realeased on TMobile as 11.2.6.6. it's the same patches and iterations.
Looking forward to either Monday or Tuesday to getting my new op9.
Selling my imac tomorrow and will not be getting a computer for awhile as I'm tired of either breaking phones or bricking them.

My first oneplus arrives tomorrow, so it's safe to say I should flash the t-mobile rom over my unlocked vanilla rom? I do live in an area where t-mobile isn't the strong hence why I dumped my verizon s21 ultra for something where I can easily control options down to the service menu etc. Funny I tested my non branded moto g and had less call drops with a tmobile sim than I did with my verizon unlocked s21 with the tmb sim.

No, don't flash the t-mo rom over anything lol. If you are on tmobile and ordered a LE2115/2125 just don't mess with it unless installing a custom rom.

Okay sounds good. I had just read above that someone said the tmobile firmware was less buggy than the unlocked version but maybe those issues have been worked out I guess.

That's more like 4G speed. 5G speed would be more than double that. But again, it depends on the area you're in and the coverage for your carrier.

Does anyone have the latest T-Mo modem files? I'm currently on the Europe 11.2.8.8 image but I've been having radio problems since I moved off of the T-Mo base (started with 11.2.4.4 global). I'm getting bad call quality, Wifi and BT issues, and seeming slow data.
I'd like to try flashing the modem files first before redoing the whole thing with MSM.
One other thing - going back to a T-Mo load with MSM won't SIM relock my phone, will it?
Thanks!

Use the Omega Kernal.
But as far as the best Variant. I've been on all of them AA, BA(which your on now) and DA. I think they are all the same besides the DA runs the smoothest out of all the variants

What would Omega kernel do for me? And as that one in the Pro forum?
I've downloaded bluspark, but haven't used it yet. Only stock kernel

Bro Omega kernal is off the chain. So much battery life. Not sure as far for connection. And yeah 9 and 9 Pro are universal.

Thanks. I'll give it a try. Do I install it thru TWRP? I've used Elemental X for so long not sure how other kernels work.

I use EX Kernal Manager
