I hope this helps anyone else in the same situation as I was. I am not rooted and wanted to have standalone 5G.

I went into the phone information settings *#*#4636#*#* changed the preferred network type to NR/LTE

then I went to preferred network type in the sim card settings and it showed 5G/LTE. As long as you leave it that way it will not change after a re-boot. If you change that setting to 2G/3G/4G/5G again you will not be able to select 5G/LTE again unless you repeat the setting in the phone information.

Now my cell mapper shows I am connected to 5G.

I have an Indian 8T (KB2001) and currently using it on T-Mobile. I get 5G but I think that most of the 5G bands are disabled as it's an Indian device. If I go through your procedure, would it enable all the 5G bands for US in T-Mobile network? TIA.

You can't access with Indian 8T to US 5G-networks because I'm sure it doesn't have US 5G bands and combinations defined to modem firmware. There is no way change it.

Changing/Editing Carrier Policy doesn't help. Or yes you will see 5G icon maybe if you can get enabled but your phone not able connect to 5G.

Same here. What does the Subscription01 do? It wasn't in there on my stock /policyman folder.

I have a OP8Pro IN2025 and the same thing happens with this as did with my old OP8 IN2017 I think it was. All traces of 5G/NR are gone from the phone with the policies I replaced.

Is there something that explains the .xml policies so I can try and get it working?

I am looking for SA NR 5G on an Unlocked OP8Pro (US) and so far I haven't been able to get any SA on this phone or the prior one.

Thanks for this (and OP). Worked perfectly on my wife's unlocked KB2005 8T. Using a standard Verizon "4G" sim that's years old from her original Pixel XL. Note the status indicator top right in the picture.
[OnePlus 8T Guides, News, & Discussion] Nikos69:
I'm coming from a Canadian provider (Bell) that uses the n66 band using kb2005. After applying the changes to enable 5g I did get the 5G symbol in the notifications and ran some speed tests, these speed tests resulted in lower speeds than on LTE alone. After moving around the neighborhood using cell mapper the 5G state was "Connected" however the speeds remained similar to LTE speeds.

Is this expected or am I too far away from a tower? I did check online and the area I'm in is 5G.

A few things to note also, when I used network signal guru to force the preferred 5g status (nr5g mode) I was not able to find this option to change to NSA/SA not sure if this is also expected?
[OnePlus 8T Guides, News, & Discussion] larsdennert:
5G is a protocol. It does not change the laws of physics. N66 only has the bandwidth that it has been licensed to. Although 5G can combine spectrum, allow more devices on the same spectrum better than 4G and is optimized by 20% theoretical, it won't create bandwidth where there is none. As things get built out, service may improve. You've future proof a bit. Most carriers likely do not yet support SA.
[OnePlus 8T Guides, News, & Discussion] Nikos69:
Thanks for the quick response, and this makes sense given my experience so far with the enabled 5G. I think it's a matter of time once the infrastructure gets built out more around my area.

when using network signal guru I get this message on "forcing and control features" it says driver not working or unknown error and then under events and signaling, they are both blank screens. Has anyone else got this message and if so were you able to fix it, thx
[OnePlus 8T Guides, News, & Discussion] BreenyBaby:
I bought the OnePlus 7 Pro GM 1917 thinking that it has 5g and this would be a good thing, I could keep using the same phone for years. I don't do much with the phone. Call and text, a little web browsing, music in the car, an occasional game so as long as it can connect I'm good. Then I notice it never connects to 5G, ever. It was one of very few 5g capable devices when I got it, to be fair. Maybe they didn't have information needed to make it work, but it seems like a dirty trick nonetheless. If this works I will be grateful, even if it doesn't I applaud you for the noble effort.
[OnePlus 8T Guides, News, & Discussion] Zuub:
I followed the guide completely and have started to see the 5G icon, but every time it connects the whole mobile network on my Oneplus disconnects..

I know the network supports it since cellmapper shows me 5g connected (albeit for a second or two) and status as un-restricted

Anyone else having this issue or know how I can debug?

P.s I'm using Etisalat that matches the n78 5g band offering of my device

I works, but partially. After reboot it is back to 4G. I noted the following - in the service menu - after every reboot you have to activate again "NR/LTE/..." mode, then the 5G works.

The "preferred network type" in phone settings is shown as "2G/3G4G/5G (Automatic)", but this selection is not available in the selection list itself?!

Install attached files.

After that dial *#800# in stock dialer, choose «engineering mode» -> oneplus_logkit -> «Function Switch» tick «VoLTE switch», «VoWifi switch» and «VT switch».

In cellular settings of your sim card(s) enable VoLTE and VoWIFI.

Hi,

Many thanks. In my case 5G is persistent after reboot, but offline until I switch between APN: (default) to (custom) and back to (default). Where custom can be anything. I tried to create new APN like default but this is somehow limited on OOS.

Please, if there is a solution for this too, could you please share it to make some other like me happy? :)

Thank you in advance,

[OnePlus 8T Guides, News, & Discussion] Rootk1t:
It also depends on what carrier profile is activated on your device. Maybe the wrong one.

You'll need to flash stock ROM or just update using full ota zip to newer version of OOS.

Hello! First of all, thanks for your guide. I was undecided about buying a Oneplus 8T because I had read many comments stating that they could not get 5G connection in Spain, and now I know I can overcome that.

My question is, will this guide work on a custom ROM (LOS 18.1, for example) or only on OOS?

If the latter, would it be possible to install LOS afterwards without losing the possibility to have 5G connection?

Thanks in advance
[OnePlus 8T Guides, News, & Discussion] bemolx:
This solution works with Qualcomm devices.

Yes, it should work with LOS because you modify modem configuration.

I have the same issue on every reboot it reverts to 4g on the 1+ 8t with Verizon. Speed is good on band 66 at about 100mbps. Band 2 is only about 15 and band 13 I couldn't verify it switches to 5g. That's on par with my zfold 3 5g in the same location on those bands. Wish I could get the setting to stick.

[OnePlus 8T Guides, News, & Discussion] Rootk1t:
Check that you have VoLTE enabled both in settings and in EngineerMode menu.

Also check that network type set to smth like NR/LTE/TDSCDMA/GSM/WCDMA and reboot phone.

If after reboot volte and 5G still don't work for you, you'll have to use QPST and PDC, to check what carrier profile is active in your phone now. It happens sometimes, that after firmware update, it resets to default or that, which not fully supported in your country.

[OnePlus 8T Guides, News, & Discussion] 21prods:
Sadly, it doesn't work. Maybe there is something I'm missing. I could not use Engineer Mode apk on LOS but I still managed to find a way to use QPST the way you explain and follow the guide therefrom. But no 5G connection still...

I'll keep trying but if you could help me out that would be great.
[OnePlus 8T Guides, News, & Discussion] 21prods:
I reply to myself. Yes, I missed something, it is necessary to have a SIM card inserted in the phone BEFORE modifying the modem settings. Now it works.
[OnePlus 8T Guides, News, & Discussion] Rootk1t:
With the removal of SIM cards, carrier profiles are usually reset, so keep this in mind for future experiments with 5G/VoLTE settings.
[OnePlus 8T Guides, News, & Discussion] max.mueller.hans:
Could you please tell us how you managed to use QPST with LineageOS? I tried to install the EngineerMode apk but it doesn't work and I also can't install those special drivers needed for QPST. Windows always gives me an error message that the driver files are not compatible. Is there a way to access those settings without having to revert back to OOS for its Engineer Mode ?
[OnePlus 8T Guides, News, & Discussion] 21prods:
Quick response, I might write a proper post with more detailled steps but I don't have the time to do so at the moment.

I assume you already have Qualcomm drivers at hand, QPST installed in your computer, ADB ready and debugging option enabled in your phone. So I followed these steps (the problem of not being able to use Engineer Mode apk is solved with steps 1 to 3, but don't forget to apply step 6 when you finish):

1. adb reboot ftm

2. adb shell

3. setprop sys.usb.config diag,diag_mdm,adb

4. Go to Control Panel – Device Manager .. you will see two unknown device.

Right click on the first one – Update Driver – browse my computer drivers - Let me pick form a list of available drivers- click on Have Disk ..- show all devices browse then go to the Qualcomm Drivers that you download earlier. Then do the same to the other unknown Driver. Choose 9018 for both unknown drivers.

5. Change carrier_policy XML files with QPST

6. adb reboot
[OnePlus 8T Guides, News, & Discussion] max.mueller.hans:
Just found out that using setprop sys.usb.config diag,adb without rebooting into ftm mode is already sufficient. From there on the steps are the same as already mentioned and everything worked.

Thank you very much !

I've already discovered why with these settings it was not connecting with 4g. I've enabled VoLTE through the logkit change, and apparently if I change the policy file, I can't connect to 4g.

So I disabled VoLTE, and copy the policies you've mentioned, and now I'm able to connect to 4g again. Just to be sure. Are you able to use these policies and have VoLTE active?

I just need to test if I'm able to connect to 5G, since I don't have near my home.
