It's stock - no changes needed. You can quite easily make changes though if needed.@HomerSp Did you have to do anything specific to the MBN file you took from the Mi 9T? If not, you might have just come up with a generalized way of enabling IMS features for a lot of other phones with QPST access!
Root is only needed to do the initial setup, it won't be needed after that. But see my text above, because I have a feeling you might have to redo it after an update.Hi after doing everything is neccessary to have root to use volte?
Sounds more like a computer issue. Try restarting comp, and phone.
yeah, tried restarting both, efs explorer is telling me that the phone does not support an embedded file system. It use to work and i was able to browse through it

* You must have root. There are several threads on how to do that, so look those up if you need help.

@HomerSp You think we could enable band 66 which is missing on the tencent version? I am assuming hardware is the same, just a setting. Thanks for all your work.
The modem hardware is different. The tencent version has less pcb layers since less bands are required to service just China.
Try grabbing EfsTools from here: https://xdaforums.com/rog-phone-2/how-to/guide-enabling-volte-vowifi-v2-t4028073 and download lte.json from here: https://gist.github.com/ccf006e4000f7ab237ec7adcef820e45I am not disagreeing with you. But i know in the past some phones just needed some edits in qpst to enable different bands. You sure about this? Or just a guess?
EfsTools.exe setModemConfig -p lte.json

Put lte.json next to EfsTools.exe and run this:
And then reboot. No idea if this'll work, but it's worth a try at least!Code:EfsTools.exe setModemConfig -p lte.json

Hah, I actually meant to quote @suzook since he was the one who asked. Which bands are enabled are stored in /nv/item_files/modem/mmode/lte_bandpref and /nv/item_files/modem/mmode/lte_bandpref_extn_65_256. The json simply modifies those to enable the same bands as the international version.My phone is being repaired, will have it back next week. What actually is this doing? Thanks.

You try this to see if B71 is enabled on TMO?

There are band checking tools on the Play Store. Try Network Signal Guru and see.

I think I only see bands 2 and 4 around here. I've definitely seen band 12, but not 66. Band 71 still seems like a niche band so it'll be hard for me to tell.
Network Signal Guru will have an option to turn off / on bands. It will give you an idea if the bands are at least detected by the system.
These are the LTE bands visable by signal guru for TMobile. 512G Global rog2 with volte enabledNetwork Signal Guru will have an option to turn off / on bands. It will give you an idea if the bands are at least detected by the system.

This is completely normal - Only one of vowifi and VoLTE can be active at one time, and vowifi has a higher priority than volte, that's why you're seeing it as unavailable while WiFi is on. As you say it should switch over to volte when you turn off WiFi.I've just used this profile with Vodafone UK & WiFi calling works, as well as the Caller display info. However according to the IMS Status VOLTE is unavailable, although when I'm not using WiFi, the VOLTE symbol does appear on the status bar.
EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim
EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim_Subscription01
EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -v
Which one did you use? It would help others if you can let them know.
Great to hear, thanks for reporting!@HomerSp, it seems it works with your recommended profile on Orange Romania. Volte appears on notification bar and it seems to keep 4G network when in a call. Will test further. Impressive work, thank you man.
