I would like to edit the Radio and Modem IMG files on the my Pixel XL 2 to enable VoLTE for my carrier which is not officially supporting VoLTE. I alrady know which files I have to edit (from the Pixel XL 1), but I don't know how to open and edit the IMG files, because for the Pixel XL 2 this is required.
Does anyone knwo how to do it?
Additonal Info:
There's a mcfg_sw.mbn file under /vendor/mbn/mcfg/configs/mcfg_sw/generic/common/WildCard/WildCard/mcfg_sw.mbn which inlcudes the Qualcomm NV Item settings which define the chipset settings which are loaded based on the inserted SIM. The default mcfg_sw.mbn file does not include VoLTE support, the mcfg_sw.mbn file for Deutsche Telekom, Vodafone UK & DE, T-Mobile US does. On the Pixel XL 1 it was enough to copy the Deutsche Telekom mcfg_sw.mbn file to the generic folder and VoLTE was working. On the Pixel XL 2 this is not working, because the mcfg_sw.mbn files are again copied from firmware/images at every boot and therefore the generic folder is overwritten. Now I'm looking for a way to bypass this. Contact me at [email protected] if you like to work on this with me.
Btw: I'm a VoLTE / IMS engineer with dedicated knowhow.

I have no idea how to do what your are asking but one thing I would do is research if the files are encrypted and or signed in a way that might destroy them if messed with. Hopefully they would just fail to flash but what if they don't fail but cause an UNfixable bootloop or whatever... again I have no idea at all but my paranoia dictates finding out more before trying it. Lol

You can't. Changing the Modem partitions on any QCOM device (except HTC devices that are S-OFF) will result in a permanent brick regardless of their unlock status.
Don't do it.
I don't think that there's a high risk to brick the phone with just modding the radio and modem partition. Because the radio was once notbworking on my Pixel XL 2, because I edited some files with es file explorer and after that I just flashed the radio and modem again and it was working fine again.
Can be removed!
I'd wait for a userdebug rom for the phone and then poke around in QPST/QXDM. Replacing and editing files at the filesystem level won't work.
Did you find anything about this?
unfortunately not..
Mod the /firmware/radio folder directly. This didn't cause any problem on my Pixel 1 XL if flashed the factory image again.
EDIT: I don't have a Pixel 2 so I don't know where modem is mounted. Please search for it by yourself
Dario, I think I figuru d wifi calling out via an xda thread. I was wondering if this would work on pixel to allow 4g+?

So lets start with this. Does your carriers VoLTE use bands that aren't available on the pixel 2? If the answer to that is no, which it probably is, then you dont have to do to modify the radio or modem. You will either need a custom ROM, an OMS overlay, or magisk to do this. VoLTE assigment isnt done by the radio or modem, it is done by the CarrierConfig app. You can use magisk and get the VoEnabler module (or use root to force enable VoLTE with the same props), you can follow https://github.com/CarbonBeta/android_device_google_wahoo/commit/0e38da5af4a93be834347bfe535ae231154530df and force enable it for your carrier (find the config that matches the MCC and MNC of your carrier) and build your own custom rom with the change, or submit it to lineage/carbon/whatever and they will probably merge it. You can also change this value by creating an OMS overlay (formerly RRO, the backend that substratum uses), and install it on any rom, however this may or may not work as android blocks overlays with signatures that don't match the system platform.

This is a chipset setting (nv item), which can be changed with QXDM.

I have tried editing Verizon's .mbn file with a hex editor and used Magisk to replace the file at boot time to enable WiFi Preferred Calling, it doesn't work. I also took out my SIM card, activated fi, then put my SIM back in, that didn't work (with the file edited).
So, if you spot something in QPST, please let me know, I really would like to figure this out for the community and myself.
What did you use to extract the img? I would love to do it at a radio level instead. F-Verizon!

I need volte profile for China Unicom too.Ims status is not registered.
Just add a specific profile or parameters like at&t's ?
I tried the mbn trick but it doesn't works on my Pixel xl. I even tried to remove entire mcfg_sw folder under /data and /firmware, but the LTE still works. BTW I sent you an email months ago but no reply

You need to get one from any Chinese phones which supports CU VoLTE. Apart from this, you need to call 10010 to activate VoLTE for your SIM card. At last, you need to comfirm the city you live have VoLTE coverage.

Can someone help me to get VoLTE work on my Pixel XL ?? I have VoLTE working fine with my mobile number (works fine on a Xiaomi Mi A2 Lite and on a Nokia 6.1), but can't seem to work on my Pixel XL, even after trying almost (except modifying radio/modem for example) anything, magisk buildprop etc... my IMS status is not registered.
Hello all,
After a week of trying, I was able to add LTE bands 2/4/12 to my XT1676 for use with T-Mobile.
It involved copying files from the EFS partition my XT1671 to the EFS partition on the XT1676. The files are located in NV\item_files\rfnv (85 files copied with no overwrites) and \policyman (13 files copied/overwritten)
I want to make a guide now for you all so you may unlock your LTE bands as well, but I'm worried that my files may contain information unique to my XT1671, Or I may not be allowed to post them here for copyright reasons.
Would any of these files leak my IMEI or SIM information, etc..?
If not, would I be allowed to post the files here for distribution?
Thanks,

Hi ! I'm looking for a combination file of the ninth version on my Samsung galaxy S9 sm-g960f.
Ready to buy or make it self, if possible.
Obviously without a device to flash them on, these are provided for purposes of extraction and tinkering only. If anyone wants a USERDATA for a specific carrier, let me know and I can get it.
Zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
Happy poking around!

You don't have G990U or G990U1 so you're in the wrong thread
