Fixed as in what? The method mentioned in this thread to enable 5G does not work in OB1 of OOS12.
[OnePlus 8T Guides, News, & Discussion] sakun-ice:
This guide is to enable 5G and DSS. The question is if it is officially enabled in OOS12 and it is not necessary to carry out this procedure.
[OnePlus 8T Guides, News, & Discussion] jcsww:
No. No changes to the 5G support on OOS12 OB1. If you use this method to get 5G working for you on OOS11. You will not have 5G working if you update to OB1 because this method does not work in OOS 12 OB1.
[OnePlus 8T Guides, News, & Discussion] sakun-ice:
It's very strange. A while ago I read of someone who tried a public beta of ColorOS in OP8 in January and 5G and DSS were activated. I assumed that it would be activated in the global version.
[OnePlus 8T Guides, News, & Discussion] jcsww:
Color OS and Oxygen OS are still separate, at least in name and a few things. Color OS is specifically for the Chinese model and market. Oxygen OS is for the EU, IN, NA/Global, and T-Mobile versions.
[OnePlus 8T Guides, News, & Discussion] Rootk1t:
Can you clarify with a bit more details, in what way it doesn't work on OB1?

Does engineering mode not start or QPST won't connect?
[OnePlus 8T Guides, News, & Discussion] -sandro-:
Does anyone know why I'm getting this? I can't delete or write to /policyman

My phone is rooted, could this affect it?
[OnePlus 8T Guides, News, & Discussion] xen423:
Root is not a problem. What's your SELinux status? What version of Android are you using? Are you using engineering mode?
[OnePlus 8T Guides, News, & Discussion] -sandro-:
1) Selinux status is Enforcing.

2) OS is latest stock OxygenOS 11

3) yes it's on
[OnePlus 8T Guides, News, & Discussion] xen423:
I am not an expert but I've had problems with SELinux set to enforcing, you could open a root terminal In termux or whatever and type "setenforce 0" without quotes and see if that helps, let me know if it does

Well, not only did this not work for AT&T, I've now even lost LTE+ 😞
[OnePlus 8T Guides, News, & Discussion] ccic2491:
I can tell you that I have AT&T and it didn't work for me. I've actually lost LTE+ now as well.
[OnePlus 8T Guides, News, & Discussion] DevilDaHusky:
i found that just adding "5G" into the lists of radios without changing anything else is best. this way you won't lose Carrier Aggregation.

Modify OnePlus 7 Pro 5G, 8 and 8 Pro, 9 and 9 Pro NR/LTE-A band combos - MT-TECH.FI

On this instruction we will modify OnePlus 7 Pro 5G, 8 and 8 Pro band combo profiles with Qualcomm software. OnePlus has limited 5G access and 4G+/LTE+ Carrier Aggregation combinations and this instruction help you to unlock. However this instruction doesn’t unlock hardware defined combinations...

here's the site I used as a guide.

Thank you it worked.

Yes if you read any of this thread you would know ATT is ****ed. In fact, I've decided to take another stab at it this past week. Here are my updates in addition to the guide:

Got ATT mobility support to flip some switches for my device on their end, not sure what all but I've spent a few hours on the phone with em purely dealing with 5G on 8T.

5G State - Restricted

Was recommended to go to ATT store and pick up a "5G SIMcard", and so I did, and then 2 more hours of phone support later...

5G State - Restricted

They've supposedly enabled and messed with everything on their end, and I the same, to the same result

I did notice my APNS were using 310 280 for some reason, instead of 310 410, but whenever I set 410 and save, the APN vanishes D:

I pretty much hate this device and OnePlus as a whole at this point

Cheers
[OnePlus 8T Guides, News, & Discussion] ccic2491:
I did all of that with AT&T months ago..... Don't hate the phone, hate the phone company. A family member of mine is on TMobile and I took his SIM card, put it in my 8T and 5G worked fine. F AT&T!!
[OnePlus 8T Guides, News, & Discussion] xstefen:
Oh I loathe ATT in a way 1+ could never match, believe me. Yeah I've had 5G (if u want to call it that) with various mvnos in testing. I've told them exactly whats going on, apparently noone can beat the computers. End up telling me im due for an upgrade for some branded p.o.s. every time :\
[OnePlus 8T Guides, News, & Discussion] jcsww:
AT&T is well known for restricting features from devices not directly sold by them. Even a Samsung sold from T-Mobile flashed with the AT&T firmware gets WiFi Calling disabled for that line as soon as the system detects a device IMEI change. I had them lock the IMEI of my old ATAT sold device while using the converted T-Mobile one and everything worked until they started implementing multiple scans of device IMEI changes every day. I ended up going back. to T-Mobile for the rural coverage after they acquired Sprint.
[OnePlus 8T Guides, News, & Discussion] georgiapi:
Yeh, running Google fi = T-Mobile on my 8t 5G no prob.
[OnePlus 8T Guides, News, & Discussion] xstefen:
On top of all the rest of the ****ery performed by ATT and subsidies, smdh...shame

I'm only here bc free line and improved coverage, but that will change soon

Has anyone tested if it is possible to do this on any AOSP custom rom based on Android 12?
[OnePlus 8T Guides, News, & Discussion] sakun-ice:
I have managed to do it on Android 12. The steps are similar to those described several pages ago, but there are a few extra steps to be taken. Steps to follow:

1. adb reboot ftm

2. Install (in your smartphone) USB Gadget Tool (https://f-droid.org/es/packages/net.tjado.usbgadget/) and check this modes: ( cser.dun.O , diag.diag, diag.diag.mdm , ffs.adb , gsi.dpl , gsi.rmnet , qdss.qdss , qdss.qdss.mdm )

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

4. Disconnect and connect your phone usb cable.

5. Go to Control Panel – Device Manager. You will see some unknown device. You should look at the so-called "Oneplus 8T", ignore the others.

Right click on the first "Oneplus 8T" –> Update Driver –> Browse my computer drivers -> Let me pick form a list of available drivers -> Click on I Have Disk -> Show all devices, browse then go to the Qualcomm Drivers that you download earlier. Then do the same to the other "Oneplus 8T". Choose 9018 for both unknown "Oneplus 8T"..

6. Add both ports in QPST Configuration. Only one of them is the one you are going to use. By clicking on EFS Explorer you will know which one it is by seeing X55 Driver in the description.

7. Change carrier_policy and carrier_policy.xml_Subscription01 files

8. adb reboot

All necessary files: https://www.mediafire.com/file/c59zj43e7d3x1pl/Necessary+Files.zip/file

My touchscreen doesn't work on AOSP A12 when booting to FTM mode, any clue as to why?
[OnePlus 8T Guides, News, & Discussion] fosgate24360:
I get the same problem(OP8t-Xtended rom)
[OnePlus 8T Guides, News, & Discussion] Rootk1t:
It is normal. In ftm the screen is black.
[OnePlus 8T Guides, News, & Discussion] fates13:
How are we supposed to use the usb gadget tool in FTM then?
[OnePlus 8T Guides, News, & Discussion] sakun-ice:
It's strange, I just checked and it doesn't happen to me. I am using Derpfest rom. It has to be something related to the ROM you use. You can try to use a USB adapter and connect a mouse to do step 2, then reconnect the usb cable and follow the steps.
[OnePlus 8T Guides, News, & Discussion] fosgate24360:
Just wanted to say thank you for this, it worked
[OnePlus 8T Guides, News, & Discussion] fates13:
Happy to note that 5G is fixed on stock A12, at least for Verizon, without having to do these steps. Upgraded my wife's phone and was surprised when the 5G icon popped up. Still have to do it on my phone on EvoX though.
[OnePlus 8T Guides, News, & Discussion] jcsww:
What was the last build of Android 11 that these steps worked on? I know they don't work on the latest EU build, at least for Telus Canada. 5G works without these steps on Telus Canada though on the build that comes with the T-Mobile to EU MSN Tool conversion.
[OnePlus 8T Guides, News, & Discussion] fates13:
Got it working on 8T on the latest Evo X thanks to @sakun-ice suggestion to use USB mouse to navigate FTM mode. Here are the files needed for Verizon, this is based on the latest OOS A11 base/firmware with A12 Evo X flashed on top so I don't know if anything has changed regarding the carrier policy files since I first posted the Verizon files a while back. Hopefully once the latest roms start using the OOS A12 blobs, this method won't be needed anymore as OOS A12 fixed 5G for Verizon. On another note, the LTE+ that I got before I modified these files for 5G tested with higher speeds than the 5G that I get now, LTE+: ~70mbps down vs 5G: 40mbps down, and the 5G that my wife gets on her OOS A12 stock 8T, maybe because the LTE+ band is less saturated than the 5G band now that everyone is switching over to 5G capable phones. Obviously, we also don't get 5G UW or C-band on the 8T. I also attached the stock carrier policy and lte feature restrictions files from my wife's stock OOS A12 if anyone wants to see what they changed to make 5G work on Verizon on the stock rom (stock doesn't have the carrier policy subscription01 file).

I also tried just straight up replacing the carrier policy and lte restriction files from OOS A12 into my Evo X phone and that worked as well. Since OOS A12 didn't have the carrier policy subscription01 file I just deleted it from my phone and everything seems to be working fine.
[OnePlus 8T Guides, News, & Discussion] jcsww:
Where can we find these files to try?

The first post should be updated noting the secret code to enable engineering mode is not working anymore on Android 12/OOS12.
[OnePlus 8T Guides, News, & Discussion] Rootk1t:
This manual works only for OOS11.

On OOS12 engineering mode/logkit and VoLTE\VoWiFi settings were hidden by developers.

Activating of VoLTE/VoWiFi toggles with Magisk module is easy if you're rooted. But requires a lot more steps if you're not.
[OnePlus 8T Guides, News, & Discussion] TheArt.:
So basically the 5G implemented in 8T is not fully activated? I am unsure if in Italy (where I am right now) it will change the situation or the local mobile operators still decide if a model is supported or not, regardless of the settings.
[OnePlus 8T Guides, News, & Discussion] Rootk1t:
It depends on the country and carrier. In the some countries it works out of the box, in another you need to install sim in supported device (like samsung) activate all the necessary options (VoLTE, VoWiFi, 5G) via carrier either automatically or by applying to support and then install sim to 8T.
[OnePlus 8T Guides, News, & Discussion] fosgate24360:

[Guide] Fix Device Not Showing Up In Fastboot Mode (Windows 10/11)

You sir are saint...I've been trying to get fastboot to recognize my OP6T for the last 8 hours. Thank you so much!

xdaforums.com
[OnePlus 8T Guides, News, & Discussion] SpyGuy47:
Thank you for that; one of the steps outlined did not work for me, however I was able to watch a video posted elsewhere (in French, which was fun) and muddled through it.

Now I have QPST open and connected, however one of the files is not present within /policyman

I'm at a loss as to how to continue.

This isn't my forte, so I really appreciate the patience I've received so far.

Edit:

It looks like I missed something; that second file is for dual sim variants of the phone, unless I'm mistaken. I'll skip that step for now.
[OnePlus 8T Guides, News, & Discussion] Rootk1t:
carrier_policy.xml_Subscription01 is used for the second sim.

If it not used in your phone, i presume the file won't be there.

I have tried adding the file through QPST as well as the Carrier Policy for it also. Makes no difference.

no the dialunlocker.bin.zip is magisk dial code unlock. (that way you dont need pc and the oppo unlock secrecy.exe ). the apk is the engineer mode apk, to make dial code work .on 11 just install apk and dial code works 12 you need the magisk zip and apk. all dial codes are in .xml in zip. heres pic of magisk.zip to show where code list is
[OnePlus 8T Guides, News, & Discussion] intheb0x:
I just updated to Android 12 today I have my bootloader unlock bin file and such so I take it I need root in order to do this? I didn't know updating to Android 12 I would lose access to everything as I had access to engineering mode but I didn't have access to those same areas you did like my rat order and such so I went ahead and updated the 12 but now I don't have access anymore so I take it I need to unlock bootloader, root, and flash the magisk zip you included?

Before I updated I had already installed the engineering APK but now when I try to install it it asked me to update it but it cannot update it Will that be an issue going forward?
[OnePlus 8T Guides, News, & Discussion] Rootk1t:
On OOS12 engineering mode is hidden.

To access it without root you need PC and manipulations with mac address and oppo unlock secrecy.exe.
[OnePlus 8T Guides, News, & Discussion] Rootk1t:
There is a universal magisk module that activates VoLTE/VoWiFi toggles and enables entering engineering mode (via dialer *#36446337#), where one can enable different carrier profiles and so on.

Tested on OOS12 & OOS13.
[OnePlus 8T Guides, News, & Discussion] replica9000:
Is there an alternative to this app? If this app can change the setting, there must be something built into Android that can change it. Maybe in the shell with setprop?
[OnePlus 8T Guides, News, & Discussion] replica9000:
So I might have found an alternative, however, I can't test at the moment due to lack of 5G in my area. I found a build.prop option that should force the phone to use NSA+SA mode.

# For special ro override property 0: not support 1:nsa 2:sa 3: 1+2
ro.vendor.radio.5g=3

Also, can someone with Verizon tell me if they can get 5G SA if they set their network to "NR only"?

In my area, it seems that Verizon has their network using the 77, 260 and 261 bands, but nothing for 5 and 66, and I get limited 5G on band 2. It also seems the status bar icon lies about 5G whenever I'm using bands 2,5 and 66, even if it's only LTE.

Edit: Seems in other areas I'm getting 5G NSA over band 66. I found my phone was choosing LTE bands that had slightly better signal strength despite having much slower speeds. When I force my phone to use bands 2,5 and 66, speeds are much better, whether 5G NSA or only LTE.

[OnePlus 8 Pro Questions & Answers] Sirtronicsskg:
So I have a china mode IN2020 that was working great.

I am in the US.

After One Plus sent down an upgrade to Andriod 11 I started had issues with the phone.

The text messages took forever to load and trying to send them was a waste of time. I changed the text message program and solved that issue.

Then the phone starts doing weird things, I would go to dial and it would just right back to the phone screen, programs crashed, etc.

The last problem was the phone now is useless the speaker (does not matter if I use the speakerphone, earpiece or Bluetooth) Is DEAD during a call. the person on the other end of the call hears me fine but, I hear nothing.

One plus says it is because of the motherboard not working with the US upgrade.

They want to charge me $350 to replace it with a US version.

I have since flashed it back to Andriod 10 and again it works perfectly.

I have also tried TWRP to flash to a custom ROM but the phone will NOT flash.

I get errors like wrong Andriod version or a check sum error occured.

Any help or suggestions...

thanks!!
[OnePlus 8 Pro Questions & Answers] dlads:
If / when you upgrade to 11 I would highly recommend a factory wipe afterwards..

Jumping between bases causes issues and a wipe fixes them, at least in my case.

It's like jumping between ROMs, always best to have a fresh start.. 10-11 isn't any different, it's possible a mod may have caused it.

So if you had viper running on 10 then you updated to 11 and didn't disable it it could have borked it, or there could have been left over remnants of it left behind..

Again a wipe would help here
[OnePlus 8 Pro Questions & Answers] Sirtronicsskg:
I was/am running stock ROM.

and thanks but I did do a factory reset.
[OnePlus 8 Pro Questions & Answers] dlads:
How did you update the phone? Via system?

Grab oxygen updater and get it from there.

No reason why it shouldn't work
[OnePlus 8 Pro Questions & Answers] Sirtronicsskg:
the phone updated automatically (via One Plus)

but after that did not work i downgraded it to 10 and then tried it again with the same result.

My understanding is the phone has a different motherboard, it is an IN2020.

They say it runs a different os...
[OnePlus 8 Pro Questions & Answers] dlads:
The board strictly speaking shouldn't mean you don't get audio? That's just wrong..

Personally I haven't used the Chinese version of the 1+8pro but if an update is available then it should accept it correctly.
[OnePlus 8 Pro Questions & Answers] Sirtronicsskg:
I agree, BUT they told me to send it it for a repair and if they replace the motherboard it will cost me $350.When i said the update should work no matter where i am the answer i received was if you are in the US and get that update it can cause issues.
[OnePlus 8 Pro Questions & Answers] Field95:
I don't think there's anything wrong with the update itself, I highly doubt it, but you can try downloading the update from Oxygen Updater and install it again, make sure you factory reset right after finishing.

If it doesn't work, then I think it might be something with your hardware, couldn't be something else I suppose
[OnePlus 8 Pro Questions & Answers] Sirtronicsskg:
Ys I did that also and same result.

It this phone goes to Andriod 11 it has the speaker issue, No matter how it gets there..
[OnePlus 8 Pro Questions & Answers] dlads:
They're wrong, just putting that out there.

So what are you meant to do?

Are they suggesting if you were in the devices homeland then it would work?

If so just use a VPN, install it and prove them wrong because they're chatting bubbles.

They ought to just fix it.
