Global full rom update (11.0.6.8) is out on oxygen updated (currently installing).
[OnePlus 8T Guides, News, & Discussion] ardax:
Saw that this morning myself. I'm running on it now. Can't say much other than that the install went smoothly.
[OnePlus 8T Guides, News, & Discussion] Scott:
Well, I tried again, and fingerprint reader is working fine this time. The only issue I have is the About device screen missing a few strings. I was able to update to 11.0.6.8 using the local upgrade option. Everything is smooth. T-Mobile bloat free.
[OnePlus 8T Guides, News, & Discussion] ddish:
I have followed all steps carefully but when i execute flash all bat it starts with the product.img hangs for a few seconds and then says "waiting for any device" and will stay that way forever. Only thing I can do is reboot with nothing done to the phone.

I updated drivers, updated platform tools put everything in one directory...

This was for Tmobile to EU

Anyone know what I am doing wrong?
[OnePlus 8T Guides, News, & Discussion] ddish:
Never mind. Loaded google generic driver and all went perfect.
[OnePlus 8T Guides, News, & Discussion] mrram:
What am I doing wrong?

Where exactly should the img files be placed. Mine are in output in python folder. It tell me "waiting for device."

What drivers are you guys using for window 10?

Thanks for this write up but where's the raise to answer gesture on global?? 😒
[OnePlus 8T Guides, News, & Discussion] ecompton59:
place the platform tools 30.5 unziped in same folder as the fastboot rom it will work
[OnePlus 8T Guides, News, & Discussion] RainGater:
My device is KB2001 (a colleague bought it from India) and currently running the latest, 11.0.6.8.KB05DA.

So, if I were to flash the latest FULL NA version from OnePlus site, 11.0.6.8 KB05AA using local upgrade option, would it work? I want to get rid of Indian bloat.

Software Upgrade - OnePlus.com

Get the latest OxygenOS updates for your device.OxygenOS is always evolving. Learn about the latest features and improvements, and get even more out of your device.

www.oneplus.com

Would it wipe the device and I can try it and find out but curious since you went through this process already?

And, you were saying that you tried again and the FP reader worked. What exactly did you try again? TIA.

EDIT: Since it's the same version, 11.0.6.8, the local upgrade doesn't work. That's okay.

But, my original question still stands: if I were to flash the NEXT FULL NA version (whenever it's released) from OnePlus site using local upgrade option, would it work? I want to get rid of Indian bloat.
[OnePlus 8T Guides, News, & Discussion] Scott:
It should as far as I know.
[OnePlus 8T Guides, News, & Discussion] RainGater:
I flashed the EU version (11.0.6.9) using the local upgrade option and the data/settings are retained. That's great news. I will have to see what happens when the next update comes and hopefully it doesn't cause any issue. :)
[OnePlus 8T Guides, News, & Discussion] sixisixsix:
so the phone will not be locked to tmobile after reflashing?
[OnePlus 8T Guides, News, & Discussion] jcsww:
Flashing does not alter the SIM lock/unlock state!
[OnePlus 8T Guides, News, & Discussion] craznazn:
Rather, you need to be unlocked to begin with. Can't flash with this method while still SIM locked.
[OnePlus 8T Guides, News, & Discussion] craznazn:
What version of fastboot are you running? Are you in fastbootd?
[OnePlus 8T Guides, News, & Discussion] mrram:
That worked!
[OnePlus 8T Guides, News, & Discussion] Questionslikeanoob:
question anyone that converted from tmobile to international did you try dual sim? Tmobile sim + another carrier? Some one wrote that putting in two sims. the phone reconizes both but does not work since there is only 1 imei. I thought for the previous oneplus 6t even though there is only 1 imei it still works since its on two separate networks
[OnePlus 8T Guides, News, & Discussion] jcsww:
Converting to dual-SIM does not enable a second IMEI. On the T-Mobile Network, you can use two SIM's with the same IMEI without any issues. That would not work though on carriers, like Sprint (two Sprint SIM's), where they use your devices IMEI to partially provide you service.
[OnePlus 8T Guides, News, & Discussion] Questionslikeanoob:
so if i convert the 8t tmobile to global and put in a tmobile sim + At&T sim it should work right?

was just confused by this guy

https://xdaforums.com/t/dual-sim-after-conversion-to-global.4221875/
[OnePlus 8T Guides, News, & Discussion] jcsww:
That is the first I have seen that.
[OnePlus 8T Guides, News, & Discussion] craznazn:
You only get 1 IMEI but it's been working. I've been dailying dual SIM since conversion so long ago. However, I use Mint (T-Mobile MVNO) and T-Mobile postpaid, so that could explain why it works flawlessly.

I just put in an ATT SIM card side-by-side with TMo and both works.
[OnePlus 8T Guides, News, & Discussion] braschlosan:
Bumping my own comment. This is the only thing stopping me from flashing the international rom.
[OnePlus 8T Guides, News, & Discussion] Lost Dog:
Where is the option to go 5G only? I'll give it a go and let you know.
[OnePlus 8T Guides, News, & Discussion] badpanda:
Does the about section still missing/corrupted?
[OnePlus 8T Guides, News, & Discussion] braschlosan:
thank you. one issue is that you have to use a recent version of their sim or it won't work. there's a small number on the front that you can use to verify its new enough. if yours is pink and says R15 you're definitely ready to go.

My sim was too old so i paid them $10 to get one in store rather than begging customer service and waiting for one in the mail. I don't think you have to change any settings to get 5G stand alone mode but ill double check
[OnePlus 8T Guides, News, & Discussion] jcsww:
The T4xxx SIM's are fine for 5G but most ask for the R15's. Either one of those is capable of 5G SA.
[OnePlus 8T Guides, News, & Discussion] Lost Dog:
I tried both an old SIM and a R-15 and both gave the same performance. On the global ROM I connect to band 66 and not the 5G bands. That being said, I have no idea if it would be any difference on the T-Mo ROM. I see "5G" on the status bar but with band 66 I don't believe it's actually 5G.
[OnePlus 8T Guides, News, & Discussion] jcsww:
What are you using to check the band? Only CellMapper can properly identify N-bands, unless something has changed. T-Mobile offers 5G on N2, N66, N41, and N71 for the most part.
[OnePlus 8T Guides, News, & Discussion] ecompton59:
Weird thing I switched carriers and told them my imei they couldn't find imei but working great Im my own problem figuring out 11
[OnePlus 8T Guides, News, & Discussion] braschlosan:
here are some screenshots to help determine if its "real" 5g or not. first is under about phone/sim status, second is "network signal info," third is "cell mapper" and fourth is "lte discovery"

Unfortunately the 5G icon is displayed for NSA and SA so you can't tell without some digging. so far i haven't found an app that works properly with 5G and im open to suggestions!
[OnePlus 8T Guides, News, & Discussion] jwarrior319:
Based on the cell mapper one your on 5G SA. When it shows only a gNB/NR connection and noe eNB/lte connection your on stand alone. To see which 5G band youre on you need cellular pro from the play store.
[OnePlus 8T Guides, News, & Discussion] braschlosan:
i tried the suggested app but it also doesn't work properly. while in stand alone it believes i am still connected to the previous LTe tower on band 2

edit: i spoke too soon. its buggy so i had to toggle airplane mode a couple times for the app to switch modes. ill try to inform the author about it and the missing data
[OnePlus 8T Guides, News, & Discussion] Questionslikeanoob:
hmm im having this same problem did 3 wipes alreayd in recovery and still stuck in one plus boot animation.. what should i do now lol

update. just fastbootd again and did the flash_all.bat again lol and worked
[OnePlus 8T Guides, News, & Discussion] Questionslikeanoob:
sorry a bit confused and new to this lol so does that mean that with the global verison and tmobile sim we are still getting 5g etc? dont need to do anything special like put back our old modems?
[OnePlus 8T Guides, News, & Discussion] Questionslikeanoob:
hmm anyone with wine level 3? i cant use netflix etc
[OnePlus 8T Guides, News, & Discussion] Questionslikeanoob:
ah lol was just about to relock without flashing
[OnePlus 8T Guides, News, & Discussion] badpanda:
Guys I went back to TMobile version and I haven't regretted it. So far I got Four updates including a large 1.2GB firmware update. Since I bought it late October 2020.

Everything works flawless.
[OnePlus 8T Guides, News, & Discussion] awr128:
I flashed back to the T-Mobile Rom and decided to root it this time and see how it goes. It's only been a couple of days but so far so good.
[OnePlus 8T Guides, News, & Discussion] Scott:
On the latest international ROM I was showing that my 5G would just drop and cell status would be "No Service" while I have WiFi on. Once I shut WiFi off the data and cell connection resume without issue. Never had this on the T-Mobile ROM. I flashed back with MSM tool and will monitor.
[OnePlus 8T Guides, News, & Discussion] craznazn:
Now that TMo's rom has most of the features that was originally missing (AOD, update speed), it seem to only really make sense if you need dual-SIM capabilities or just want to use global for perhaps faster update to Android 12 in the future. Carrier ROMs seem to be fairly fast when it comes to incremental patches but are woefully slow when it comes to big ones.

Regarding 5g performance, I can only test NSA here since I don't have nearby SA towers. 5G NSA works fine.
[OnePlus 8T Guides, News, & Discussion] Lz3807775t:
Speaking of T Mo I just got this today
[OnePlus 8T Guides, News, & Discussion] awr128:
I received the notification for the update also, but haven't applied it yet. Kind of weary about updating after all the issues global users had after the last update.
[OnePlus 8T Guides, News, & Discussion] Lz3807775t:
So far it seems ok but I've only had it for like 2 or 3 hrs
[OnePlus 8T Guides, News, & Discussion] awr128:
Any noticable changes?
[OnePlus 8T Guides, News, & Discussion] Lz3807775t:
Only had it for a few hours , so not yet , I'll run it thru is paces and see how it goes today
[OnePlus 8T Guides, News, & Discussion] ysfk7:
any good news?
[OnePlus 8T Guides, News, & Discussion] Lz3807775t:
So far everything is good , not having any problems , but really I think this was just the security update , it was only 124 mb file
[OnePlus 8T Guides, News, & Discussion] ysfk7:
:). i was referring to radiohead7778580 about the modded MSM Tool for a straight conversation without the need to unlock
[OnePlus 8T Guides, News, & Discussion] Lz3807775t:
Oh sorry
[OnePlus 8T Guides, News, & Discussion] ddish:
I too went from global back to T Mobile stock and its much better at 5G and switching between LTE and 5G. The options you get with the stock rom are just not available with the global rom and those seem to be crucial to getting good 5G speeds and switching between 4G LTE and 5G. On Global it would take forever to connect. The only thing I miss is the dual sim. Hopefully that can be figured out. Or if someone can get the mobile data/modem configs into the global rom that would be ideal. Really no other need for root except for ad blocking but I am using Blokada and it works pretty good. T Mobile bloat can be removed with ADB
[OnePlus 8T Guides, News, & Discussion] ysfk7:
All i need just dual sim. Mine already sim unlocked and i got the token from oneplus today.
[OnePlus 8T Guides, News, & Discussion] Lost Dog:
I went back to stock today as well. Reception is much better with Stock T-Mo unfortunately. I would have liked to have stayed global but the T-Mo modem seems to be much better in my area.
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
Did Tmo apply the hotfix for buggy update?
[OnePlus 8T Guides, News, & Discussion] Lost Dog:
Not sure, but the latest update has been solid. No issues at all.
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
Just wish Tmo would get on board with the stock icons. I know it's only cosmetic but.....
[OnePlus 8T Guides, News, & Discussion] Lz3807775t:
Yes I think it came with the security update
[OnePlus 8T Guides, News, & Discussion] awr128:
TMO never got the buggy update. Only the unlocked users got it
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
I removed some TMO via adb..... Can all if it go without messing up the device?
[OnePlus 8T Guides, News, & Discussion] jcsww:
That all depends on what you want to remove. Personally, I just remove the T-Mobile apps and any other pre-installed junk, like Drive. Package Info is a decent app to help you see the package names for whatever you want to remove. Personally, I wouldn't remove anything major, although I do remove ZEN Mode and don't have any issues from doing so.
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
So I've been back on the TMO Rom for about a week. It's oddly different than the global Rom. The settings are a little different. The network connection seems 1000 percent more stable. I have yet to have to reboot my phone because texts aren't sending ( my biggest issue with the global) the downside is I don't think the TMO variant isnt as up to date. I have issues triggering full screen navigation gestures sometimes. Fingerprint sensor seems to work better though. Such a toss up. Am I the only one having issues with the network on the global Rom? Phone calls not working (cell and wifi calling stop) texts failing (unless it's a RCS)? I'm tempted to flash back now that there's a newer update but might wait a little bit.
[OnePlus 8T Guides, News, & Discussion] jwarrior319:
Im using the EU(BA) version. I started when i was still on tmobile and now straight talk(tmo sim) with good experience on both carriers. I tried global(AA) when the full rom was finally released and was having same issues you had but EU version is flawless for me and supports 5G SA and NSA.
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
Maybe it was your TMO sim card? So your saying the EU version works better for you?
[OnePlus 8T Guides, News, & Discussion] jwarrior319:
Global is same with my ST sim too so a general tmo network thing i guess. EU works better imo than TMO firmware. Tmo seems to have background bloat that slows down their firmware.
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
Doesn't seem like it effects all tmo users though. I just flashed back to the global build. Going to give it a go for a few more days and see how it goes. I'll try the EU one if I encounter issues again
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
Also I'm guessing we can't swap builds through oxygen updater? We have to use fastboot?
[OnePlus 8T Guides, News, & Discussion] Questionslikeanoob:
hmm the eu verison has dual sim?
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
Looking through the dialer shortcut which preferred network type should be set for tmobile? I switched it to NR/lte/gsm/wcdma.

It was on one that had tdscdma which I'm not sure tmobile even supports
[OnePlus 8T Guides, News, & Discussion] craznazn:
For what it's worth, I've been dailying the EU (BA) rom since the beginning of all this, and never had any issues.

Yes, EU has dual sim

Just use local upgrade. The only thing is you can't downgrade with local upgrade, so if the version number is lower, then you gotta do it via fastboot or wait until the next patch
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
Worked perfect. On global it seems if I manually toggle wifi I lose network functionality. Texts and calls stop. Volte and Vowifi icons don't switch properly As if they are stuck. So far I haven't had a single issue with that on the EU build. Network seems to function just fine. Something is definitely broken on the global.
[OnePlus 8T Guides, News, & Discussion] Questionslikeanoob:
Whoa your Global version sounds iffy lol. I never had that problem on Global but i noticed my 5g is much slower than regular LTE. Also some other network problems. I switched over to EU now as well. So far things looks good for dual sim. I have the r15 sim from Tmobile but dont see 5g SA on cellmapper yet guess im not near a tower
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
I've had this issue since global dropped. If I let the phone go from wifi to cellular on its own it switches no problem most of the time so it's usually a non issue. But when it is an issue I usually don't notice right away so I miss calls and texts until I reboot.
[OnePlus 8T Guides, News, & Discussion] just4sc:
What city are you at? I'm in SoCal and worried that the EU won't work well. I really want the dual sim since I can use data on one sim that doesn't have TMO kickback and calls and text on my main sim that has TMO kickback.
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
I'm in FL. I haven't really been able to test anything outside of my house yet since I was home all day yesterday but so far Rock solid.
[OnePlus 8T Guides, News, & Discussion] craznazn:
T-Mo's network is pretty much the same everywhere (2,4,5,12,66,71 + n41 n71). My primary LTE anchor is B66 and B2 which looks like it should be the case in most metropolitan parts of SoCal. I've also used the EU rom plenty in san diego and it's perfectly fine.
[OnePlus 8T Guides, News, & Discussion] jcsww:
Band 5 is pretty much non-existent except for a small on the coast of one of the Carolina's. Here in coastal Virginia, we have a lot of N2 and N66 for T-Mobile 5G, which seems to be quite common for T-Mobile service up and down the east coast.
[OnePlus 8T Guides, News, & Discussion] craznazn:
Do you mean B2/B66 anchor LTE? TMo does not have n2 or n66, only n41 mid-band, and n71 long range (excluding mmwave)
[OnePlus 8T Guides, News, & Discussion] jcsww:
No! I mean N2 and N66, which they do have all over this area. Richmond, Hampton Roads, Glaucester, are just a few of the examples where they have 5G deployment on those N bands.
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
What app are you using to see bands
[OnePlus 8T Guides, News, & Discussion] jcsww:
CellMapper
[OnePlus 8T Guides, News, & Discussion] ysfk7:
sorry, what's the difference with Global vs EU rom? big difference? i had Tmo 6T and TMo 7T and converted to global with no issue, all works with dual sim (ATT and TMo sims).
[OnePlus 8T Guides, News, & Discussion] Kiwi616:
Hey, I'm thinking of going back to the T-Mobile ROM as well. Had dialer (not dinner) issues with the Google dialer and texts. Which guide did you follow and where did you grab the stock ROM ? I search around, but can only find conversion to global vs going back.

Thanks in advance.
[OnePlus 8T Guides, News, & Discussion] awr128:
MSM back to the TMO ROM. That's the best way, it will wipe your phone so make sure to back up. I'm going to give the EU ROM another try. I'm getting horrible data speed when I switched back to TMO ROM.
[OnePlus 8T Guides, News, & Discussion] craznazn:
MSM is the safest way to go, versioning differences will probably cause a kernel panic on boot. That said, if you're on global, give EU a shot first, just local upgrade and don't need to wipe.

Edit, actually, why don't you try to local upgrade with a t-mobile OTA? Is there a full t-mobile OTA available I don't even know...?
[OnePlus 8T Guides, News, & Discussion] awr128:
I don't think there are full TMO upgrades available. I think it would honestly be safer to MSM back to TMO then to try and local upgrade on top of a global or EU ROM.
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
I haven't noticed any difference in coverage, speed, switching over between the tmo, or EU Rom. I'd say the global rom has issues switching but speeds are the same for me in my neck of the woods but as always ymmv
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
How do I figure out which sim card I have? Is the number on the sim?
[OnePlus 8T Guides, News, & Discussion] jcsww:
Any SIM with R15 on it will work fine without the need for an update to support 5G NSA/SA. There are SIM's with TM 9263, which also work perfectly fine for 5G NSA/SA.
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
Thanks. Looks like I have the 9263 sim. I've had it for the last couple years and when I got my 8t it's the same sim in the box so I guess I'm good
[OnePlus 8T Guides, News, & Discussion] jcsww:
That is what I use in mine as well. I have an R15 that came in the box, but I would rather save that one in case something happens to this SIM. I don't like paying for new SIM's. :P
[OnePlus 8T Guides, News, & Discussion] just4sc:
How long does it take to boot up after converting to EU from TMO? I'm seeing those spinning dots for about ten minutes already. I didn't see any errors.
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
Usually takes a few. Did you wipe in recovery?
[OnePlus 8T Guides, News, & Discussion] just4sc:
Yeah, I did...but didn't erase data. It booted up fine after wiped everything completely. Thanks!
[OnePlus 8T Guides, News, & Discussion] Smallsmx3:
Don't forget to download oxygen updater and flash the full build
[OnePlus 8T Guides, News, & Discussion] badpanda:
$5/each on ebay ;) R15
[OnePlus 8T Guides, News, & Discussion] live4thamuzik:
Worked great!

One thing I did notice was that the quick toggle for Wifi Calling is gone. However you can still turn it on or off in Settings>Wi-Fi & Network>SIM & Network> SIM 1
[OnePlus 8T Guides, News, & Discussion] ysfk7:
thanks for the guide. Converted to Global, did Local Global Full (2GB) update 11.0.6.8.KB05AA, then relock bootloader. I just need the dual SIM function. I can always re-unlock the bootloader if I need to convert back to Tmo and/or root.

Question: If I turn off OEM Unlocking, and in the future I need to unlock bootloader again, do i need to request for a new token? TIA

edit: after the relocked the bootloader, rebooted, it showed there's a new update 11.0.7.9.KB05AA. I did local incremental update 291MB and worked.
[OnePlus 8T Guides, News, & Discussion] awr128:
You don't need to request a new code to unlock your bootloader, You keep using the same one you already have.
[OnePlus 8T Guides, News, & Discussion] ysfk7:
Thank you kindly
[OnePlus 8T Guides, News, & Discussion] risensunx:
I am on Global 11.0.6.8 and I having the same issue with missing calls and texts when the phone goes from wifi to cellular and vice versa. It is driving me crazy since I would have to reboot to fix it. It sounds like the EU version does not have this issue. Do you know if there is a way to flash the EU version without using the MSM tool? I am trying to avoid wiping my info if possible. Thanks.
