[OnePlus 8 Pro Questions & Answers] angelvip3r007:
So, I don't know how, but both VoLTE and VoWiFi have suddenly reappeared.

Tested VoWifi and it worked!!

I put the phone into airplane mode, turned on wifi and I was able to call my home number...
[OnePlus 8 Pro Questions & Answers] Mattycee:
Did you dirty flash 11 over the top or factory reset to install (If coming from a Beta)

Maybe Telstra are tweaking some settings their end and allowing it to connect without the hoop jumping. 5G worked without intervention after the 11 update, so who knows?
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
I downloaded the OTA using Oxygen Updater then flashed using local flash in settings. I came from oos10. Fully stock, no root.
[OnePlus 8 Pro Questions & Answers] Mattycee:
Interesting, who is your carrier, are you with Telstra?
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
Yep, Telstra. Thing is I updated my phone on Sat or Sun, but the indicators have only reappeared in the last hour or so.

The only thing I have done in the past few hours was reboot the after turning off USB Debugging. :confused:
[OnePlus 8 Pro Questions & Answers] Mattycee:
Cool, I'll return my phone back to 10, get it all set up with VoLTE/Wifi, use the updater to go back to 11 then see how it goes. Hopefully it sticks!

Thanks for the info.

I will be the guinea pig, will see how long it takes to come back on mine (If it does at all)
[OnePlus 8 Pro Questions & Answers] happiboi:
That's weird - cos that's the same process I took - but them VoLTE/VoWifi haven't come back yet.
[OnePlus 8 Pro Questions & Answers] Mattycee:
When did you update to 11? Maybe it takes some time (Like RCS does)
[OnePlus 8 Pro Questions & Answers] happiboi:
I think I updated late sunday arvo.... mmm maybe it'll come back tomorrow-ish.? i hope lol
[OnePlus 8 Pro Questions & Answers] JetOoi:
Seems like a lot of progress, thanks guys. You guys are really awesome. Anyone tried directly update from ota and confirmed Volte and vowifi lost? Manually download using oxygen updater and then manual flash in system update will give different result vs direct ota update using system update?
[OnePlus 8 Pro Questions & Answers] offlineon:
Interesting. It just might be all carrier activated.

In that case, can someone with Telstra try rebooting with wifi enabled and connected. Then activate flight mode and as quickly as possible reactivate wifi. Hopefully this will possibly prompt VoWiFi and then Volte provisioning. Just a guess. Anyone?

---------- Post added at 08:43 AM ---------- Previous post was at 08:22 AM ----------

I should add that call over wifi should be set as the calling preference and provisioning might take some time
[OnePlus 8 Pro Questions & Answers] Mattycee:
I have done the test and it still isn't working. I rebooted with all flags enabled, turned on Flight mode and then wifi and it didn't do anything unfortunately.

How long did you suggest leaving it? I left mine for a few minutes.
[OnePlus 8 Pro Questions & Answers] offlineon:
Maybe it takes some time at first - maybe 30-60m??

With all the stuff I was trying I was definitely rebooting every few minutes & using the above method.

It does seem to help even now that VoLTE works and I restart my phone - but wish to speed up VoLTE/VoWiFi availability in an area with RF interference.

I believe the modem config is overwritten on upgrade so I don't believe pre-enabling VoLTE on Android 10 before upgrading is a factor.
[OnePlus 8 Pro Questions & Answers] Mattycee:
Are you saying to keep flight mode on (Wifi on) for 30-60 minutes?
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
And they're gone again... ¯\_(ツ)_/¯
[OnePlus 8 Pro Questions & Answers] offlineon:
Yeahhh.. but my theory is that it could be a carrier rollout and further more it might be starting in Victoria first.
[OnePlus 8 Pro Questions & Answers] Mattycee:
Yeah I have noticed that it seems to be those in Victoria that are getting it first. Maybe it is going to roll out over all states in the coming days/weeks/months.

It seems to be a little patchy too, with it coming and going, which could lead to it being down to some testing that is currently happening.
[OnePlus 8 Pro Questions & Answers] offlineon:
On VoWiFi it holds so long as I don't leave an AP. On VoLTE it drops every few hours for a few minutes. Once VoLTE goes, VoWiFi won't reconnect quickly without a reboot and that flight mode trick.

Definitely patchy as you said Matty.
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
And they're both back. Did absolutely nothing.
[OnePlus 8 Pro Questions & Answers] prottura:
Hi guys,

First of all just wanted to thank those of you who have been doing amazing work to get this going, it's a real asset, especially for someone like myself who lives in an Area where the Cellular Signal is quite sketchy at the best of times.

Just wanted to clarify however, I'm currently running Oxygen OS 10.5.13.IN11AA (Global ROM) and have already implemented the VoLTE and VoWiFi fix via EFS Tools. If I am to simply upgrade to Android 11 Stable (Using Oxygen Updater tool) that it should pick up my VoLTE and VoWiFi connection after some period of time without further intervention on my end, even though the previous method to get it working will be wiped as a result? (I'm also with Telstra and live in Melbourne).
[OnePlus 8 Pro Questions & Answers] happiboi:
it's a bit hit and miss with this. From the handful of reports so far - seems like those based in VIC have intermittent success with retaining VoLTE /VoWifi.

FWIW, if it's important to you as a feature, I would stay on Android 10 for now
[OnePlus 8 Pro Questions & Answers] Mattycee:
Hey Happiboi, which state are you in? No joy with the arbitrary waiting a few days? I do believe its a regional thing, but we have only had 2 people getting it, it's not a large sample size to go from. My mucking around has stopped RCS working again, so will hopefully have the back up and running in the next few days. Who knows we all may have them working if this becomes more widespread.
[OnePlus 8 Pro Questions & Answers] happiboi:
Hey Matty - i'm in QLD... at the moment still no joy for me :(

guess its a wait and see game
[OnePlus 8 Pro Questions & Answers] Mattycee:
It sure is, I am now without VoLTE/Wifi or RCS due to my mucking around! I have left Wifi off to try and get RCS back, but so far there is no joy.
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
I went for an hour walk around my neighbourhood today. VoLTE stayed on the whole time.

When I got home VoWifi kicked in immediately when the phone connected to my home wifi. That was about 40 mins ago.
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
Just as a bit of an update, went for another walk. Came back but both indicators were gone.

I decided to put my phone into flight mode and turn on wifi, called my home number and the VoWifi indicator appeared and the home phone rang.

VoLTE was also back too when I switched off flight mode.

I wonder if there is a bug in OOS11 or if this is a symptom of us turning these features on on a phone not officially supported in Australia.
[OnePlus 8 Pro Questions & Answers] Mattycee:
I'm still hoping it spreads to other states as it's now showing on mine here in NSW. Has anyone else had theirs start working?
[OnePlus 8 Pro Questions & Answers] Mattycee:
It looks like RCS is being rolled out natively in the app via Google. Someone on Whirlpool posted they've just received it on Optus, so it's coming for all it seems!
[OnePlus 8 Pro Questions & Answers] prottura:
Awesome news to hear about Google finally rolling out RCS, it's about time.

Is there any update on the A11 VoLTE/Wi-Fi Calling situation in Aus? I really would love to go to A11, especially so I can have an AOD as 3rd Party Apps aren't as good, but obviously need to retain VoLTE + Wi-Fi Calling.
[OnePlus 8 Pro Questions & Answers] Mattycee:
I have had no joy and have gone back to Android 10 in the meantime while it either rolls out nationwide, or someone works out how to get the old workaround running on Android 11.
[OnePlus 8 Pro Questions & Answers] Mattycee:
Do we have an update on whether the VoWifi/LTE is still working on the phones of those who had it already, and has it spread at all? I took my phone back to Android 10, but got the 11 update without using Oxygen Updater so updated it anyway.

RCS stuck as I knew would happen, but lost both VoWifi/LTE so was looking for an update.
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
Mine comes and goes. I'm not worrying about it anymore. I did however have to set my preferred call over mobile.
[OnePlus 8 Pro Questions & Answers] happiboi:
RCS here as well but still not VoLTE/VoWifi..

at the moment the method to geet VoLTE/VoWifi workign still seems to require root access to the phone :(
[OnePlus 8 Pro Questions & Answers] hanymedic:
Critical error. The operation has timed out.

Hi Dear,

Thanks for your appreciated post but did you figure out how to solve the "Critical error. The operation has timed out. " error ?

I am stuck with this error with my OnePlus 2013 running Android 10; and tried all *#801# options including even the Engineer Mode Toggle but didn't work as well.

Please, let me know if you got a fix.

Thanks
[OnePlus 8 Pro Questions & Answers] Sull81:
As much as I would love a OnePlus 8 Pro and basicay settled on it until I found this pist is it really worth the stuff around to get VOWIFI working where you can get the same spec phone Oppo Find X2 Pro for $200 dollars more? Wifi calling is a major selling point for me as I get no reception at home.

[OnePlus 8 Pro Questions & Answers] prottura:
Hey guys,

I've been doing some reading to see whether it is possible to do anything about getting VoLTE and VoWifi to work on Android 11 without rooting our Devices in order to gain access to PDC and it looks like following the steps provided in this thread which was mentioned on the Australian Whirlpool Forums worked:

https://xdaforums.com/oneplus-8-pro/how-to/guide-enable-volte-vowifi-devices-root-t4105723

To summarise my steps to getting this working:

- Downloaded the old OnePlus LogKit Tool which is linked in the pinned Post at the start of that Thread.

- Enabled the VoLTE and VoWiFi Switches under the 'Function' Tab within the old OnePlus LogKit App.

- Rebooted Phone.

- Reinstalled current OnePlus LogKit Tool (Process is mentioned on how to back up the latest version & someone has also linked it a couple of pages into that Thread as an attachment).

- Enabled the 'VoLTE & Wi-Fi Calling' toggles under SIM Menu and set my Calling preference as 'Call over Wi-Fi'.

- To get these working and to test their functionality, I put my Phone into 'Aeroplane Mode' and then re-enabled Wi-Fi which displayed the 'VoWifi' badge on the top Navigation bar, it also showed 'Wi-Fi Calling' while I was attempting to make a call.

- VoLTE worked also once I turned off Wi-Fi and turned on Mobile Data and then made a call as it stayed as '5G' and didn't drop down to '3G'.

For reference however, I'm running the initial build of Android 11 (11.IN11AA) and I have yet to install the latest update as the person in the Whirlpool Forum had not tested this method on the latest update mainly because it's said that the latest update breaks 5G access, and mine is working on the initial release.

I'm on the Telstra Network in Victoria for reference and my Phone is NOT rooted.

I have noticed that if you do use Aeroplane mode again, it can remove the 'VoWifi' and 'VoLTE' badges from the Navigation menu until you repeat the trick to re-enable Wi-Fi after turning Aeroplane Mode back on and then turning it off once the 'VoWifi' badge reappears.

Not sure if this will help anyone, but maybe it might give us hope on how we could find a more stable solution that doesn't require Root access.
[OnePlus 8 Pro Questions & Answers] Sull81:
Have you had any issues since you completed the steps in your post. I am tossing up whether to buy the one plus or Find X2 Pro.
[OnePlus 8 Pro Questions & Answers] happiboi:
Still have not found a way to get VoWifi/VoLTE to work on Android 11.... (not without root)
[OnePlus 8 Pro Questions & Answers] prottura:
The only problem I've found is sometimes that the VoLTE or VoWifi can drop off (Mainly once you've gone outside away from a Wi-Fi Signal for an extended period of time), and the only way to re-establish both is to do the turn on Aeroplane Mode and then turn on Wi-Fi and then try to make a Call to force VoWi-Fi (And subsequently VoLTE) to come back online (You obviously need to be connected to a Wi-Fi Network to do so) and then obviously turning off Aeroplane Mode once you've seen that VoWifi appears.

Sometimes VoWiFi can drop off while you're on a call (Although in my case, I suspect it could be something to do with my Mesh Wi-Fi Setup at home and it potentially changing between AP's during a call) - I've as a result set my preference for calls to be placed over Mobile Network.

Ideally, I'd love it if someone would test OPB4 or the latest Stable update with this technique as I'd like to be able to upgrade ideally and keep these but also not lose 5G (I hope it's been fixed for OPB4 and the subsequent Stable release that comes of it).
[OnePlus 8 Pro Questions & Answers] Sull81:
Thanks for the response mate. I think I will go with the Oppo Find X2 Pro as that phone is supported by Telstra. I really wanted to try the OnePlus but with it not being supported and the fact I need WIFI calling at home as there is no reception it just makes sense to go with the Oppo.

Might be worth adding your voices to this suggestion on the OnePlus forum!?

[OnePlus 8 Pro Questions & Answers] Mike_Fre:
We have a working solution without root that is easier than previous instructions.

You still need the old toolkit app and #*800# to activate vowan and volte functions if you haven't done in the past.

Do adb reboot

Enjoy vowifi and volte.
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
Unfortunately, that doesn't work for me. I can't see the phone in the PDC app.

I've got an IN2023 running OOS 11.0.2.2IN11AA
[OnePlus 8 Pro Questions & Answers] Mike_Fre:
I would ensure you have used QPST 2.74.460 and the Qualcomm Driver offered on:

I used the WWAN option and this is what appeared on the Advanced PDC app.
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
Yep, tried that. This time I could see the phone in PDC. Applied the steps to activate Sim 1 and Sim 2. Rebooted but still no VOLTE or VOWifi.

Repeated the process and noticed "Telefonica_UK_Commercial " were both set back to inactive.
[OnePlus 8 Pro Questions & Answers] DREW76:
I had the same issue with the IN2023 version.

I opended EFS Explorer first ( and let it do its scan), while scanning I then opend PDC and the phone showed and was able to apply trhe UK settings as previously mentioned
[OnePlus 8 Pro Questions & Answers] Jaansburger:
Thank you @prottura, that worked for me using a OnePlus Nord (Global Version AC2003).

However, I needed to also update the "profile" to use "Telefonica_UK_Commercial" (PDC Tool)

I used this YT guide to change the profile:

Running on OxygenOS 10.5.9 (Android 10).

I still had an issue where every now and then my VoLTE / VoWiFi would drop and stop working, and if I get home and just go into "Flight Mode" and only enable WiFi after, it would re-register IMS and re-activate VoLTE / VoWiFi capability.

Turns out that the "Telefonica_UK_Commercial" profile sets an IMS UserAgent value of "Telefonica VoLTE Qualcomm". I used the EFS Explorer tool from the above Qualcomm QPST toolset to update that UserAgent value to "Telstra VoLTE Qualcomm" (taking a wild guess), and after rebooting my Nord now automatically enables VoLTE/VoWiFi within having to to the "Aeroplane mode" trick to force it anymore.

The location of this file in the phones EFS is: nv\item_files\ims\ims_user_agent

Attached is my "Telstra" version - used a hex editor to ensure file size stays exact and that 0x00 null padding is not converted to spaces by notepad. You'll need to unzip it first.

Also, if you have difficulty getting 5G going on your Nord, look here for that:

Thanks to all for your contributions!
[OnePlus 8 Pro Questions & Answers] prottura:
Hey mate, that's a fantastic write up and good work with all the research.

I can confirm that the method also works on Android 11 Build 11.0.2.2.IN11AA (I'm using a OnePlus 8 Pro Model IN2023 on the Telstra Network in Melbourne, Victoria)

The only thing I haven't been able to test is whether I will have 5G access, as at work (Where I was working on the fix this morning) doesn't have 5G available, my home area does so I can test this later today and report back (I did however, prior to getting this working had tried the VoLTE_OEM_Lab Profile which gave me 5G, so I wonder if this can be used with the ims File, but I suspect it wouldn't work).

The only other weird thing I noticed was as angelvip3r007 had previously mentioned, trying to apply the "Telefonica VoLTE Qualcomm" Profile would show as "Active" when activating it, but then after completing the "adb reboot" command then going through the steps to check whether it had actually applied, it would say "Inactive" when I would open up PDC again. The way around this, was to get the "Telefonica VoLTE Qualcomm" Profile into a "Pending" state, and then open up EFS Explorer and add the "Telstra VoLTE Qualcomm" Profile into the ims Folder before completing the "adb reboot" command.

I guess my only other question would be whether this method would survive subsequent updates that will be pushed out by OnePlus in future.

EDIT: So I've just got home to test out 5G in my area and unfortunately it's not working, maximum I'm picking up is 4G+. I will have to try your 5G fix and see if it works.

EDIT2: After following the steps in this Video (Video is in French, but it's simple enough to follow, I also didn't have to use the version of QPST listed in the video (Required Files for this Tutorial are linked in the description of the Video itself), as the version of QPST that we've used in the above install of VoLTE/VoWiFi worked perfectly fine), I was able to get 5G (Make sure to reboot your Phone after replacing carrier_policy.xml's) and keep my VoLTE/VoWifi which has been rock solid, Video has been linked below:

[OnePlus 8 Pro Questions & Answers] happiboi:
Thanks for the feedback - i will look into giving this another go too to get the Volte/voWifi going then.
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
I'll give this another go tomorrow. I assume "Telstra VoLTE Qualcomm" is the mbm file posted in a link by Happyboi earlier in this thread?
[OnePlus 8 Pro Questions & Answers] prottura:
Nah, I actually used the 'ims_user_agent' File linked above by Jaansberger.

The only thing I used from Happyboi's original exploit, was the Engineering APK File to enable 5G. However, make sure you don't install the Engineering APK before you do the initial VoLTE/VoWi-FI Process listed above by Mike_Fre.

So basically order of steps I followed:

- Mike_Fre's steps to enable the 'Telefonica VoLTE Qualcomm' Profile.

- Jannsberger's step to insall the 'ims_user_agent' file (Before doing the adb reboot step listed in Mike_Fre's Post).

- Watched and replicated the YouTube video (Which I linked in my post above), to enable 5G and still have VoLTE/VoWi-Fi.

Hope this clears things up for you, but if you have any further questions, I'd be happy to try and help.
[OnePlus 8 Pro Questions & Answers] angelvip3r007:
That worked perfectly!!! Thankyou!!!
[OnePlus 8 Pro Questions & Answers] prottura:
Hey Happyboi,

Quick question for you. Would it be worth me changing my carrier_policy files from those that were supplied in the French YouTube Video to the ones you've supplied if I have the IN2023 Model? What would you say is the Positives/Negatives of changing them?

hi,

I would like to know if the bootloader of Atom Exec --> eboot.nb0 is the same as that of Atom life or of the O2 Atom --> eb0.nb0

Is the bootloader common among the PXA272x platform or is it dependent on the disk on chip (DOC) for the particular device.

I have a dead O2 stealth and i cant find its bootloader in its upgrade package which i downloaded from O2 website. Its upgrade package just has a 52MB file named as gbcall.nb0.

Can i use the default eboot.nb0 from Atom for flashing the DOC of the O2 stealth ? both are PXA272x platform with wm5 ?

Is there any other method of extracting bootloader from the file gbcall.nb0 ?

Anyway I need help regarding the Jtag Pinouts of the O2 stealth i recon i will start testing with the following pins in view

please post your experience and thought on the pinouts
[iPAQ rw6828, XDA Atom Software Upgrading] tjkhattak61:
I can comment only on Atom Exec. Atom has an MN1 bootloader and Atom Exec has an MN2 bootloader, so both are different.
[iPAQ rw6828, XDA Atom Software Upgrading] sirrus_linux:
thanks tjkhattak61 for your quick reply

so i assume since the bootloaders for atom and atom exec are different then the atom bootloader will not work for flashing the bootloader of the dead O2 stealth.

if that is the case it would be nice if someone would help me extract the O2 stealth bootloader from the upgrade package provided by O2 on their website
