[Treble][RIL] Qualcomm device and in-call audio not working? Check this out

[linuxct]

Hello,

After a few weeks of having Project Treble GISs running in my Razer Phone, I had one big issue to solve, and that was the in-call audio. I stumbled upon a few people in #phh-treble Telegram group that suggested me to use ZUK (MSM8996) patches to get it to work, but unfortunately they weren't fully working... because of a missing apk from my device's stock image (which I didn't know until 2 or 3 days ago). Starting from there, I worked on it quite a lot of time until almost giving up, to then finally getting it to work just now.

Steps I followed:

1. Pull from your device's stock image the following files (they may not be in /system and instead be located in /vendor, depends on your OEM's Treble implementation)
- app/QtiSystemService
- app/QtiTelephonyService
- framework/qcrilhook.jar
- framework/QtiTelephonyServicelibrary.jar
- etc/permissions/privapp-permissions-qti.xml
- etc/permissions/qcrilhook.xml
- etc/permissions/qti_permissions.xml
- etc/permissions/telephonyservice.xml
- priv-app/qcrilmsgtunnel

2. Fortunately, those APKs will contain a .dex inside of them, but in case they didn't, you'd need to first deodex your rom based on the vdex files located in /system/framework/oat. However, the jars will definitely and for sure won't have the inner .dex classes. You'll need to use a tool such as vdexExtractor to get the final .dex files for qcrilhook.jar and QtiTelephonyServicelibrary.jar. Then, open the metioned .jar's as zip files, embed the .dex inside and done.

3. The tricky part comes now: With a tool such as APKTool, decompile the qcrilmsgtunnel.apk file you've extracted from your Stock ROM image. I'm not going to go throught the steps to perform that. Now, open up the AndroidManifest.xml and find the line:

<uses-library android:name="[email protected]" />

and replace it with

<uses-library android:name="[email protected]" android:required="false" />

Recompile the apk and, without signing it yet, put it in a safe place.

4. Open up the other APKs and remove the META-INF folders from inside of them (the signatures). Now, download a copy of SignAPK and sign every apk (including the ones we've removed the signature from, plus the modded version of qcrilmsgtunnel.apk with the platform keys (platform.*) from Android AOSP.
You can do so by using the following command:

java -jar /path/to/signapk.jar /path/to/platform.x509.pem /path/to/platform.pk8 NameOfTheApk.apk NameOfTheApk_signed.apk

5. Open up the files qcrilhook.xml and telephonyservice.xml and ensure that the file="" path points to /vendor. i.e:

file="/vendor/framework/qcrilhook.jar"

6. Move the files to your device according to this table:
- app/QtiSystemService -> /system_root/system/app/QtiSystemService (replace)
- app/QtiTelephonyService -> /system_root/system/app/QtiTelephonyService (replace)
- framework/qcrilhook.jar -> /vendor/framework/qcrilhook.jar (delete the original file wherever you found it)
- framework/QtiTelephonyServicelibrary.jar -> /vendor/framework/QtiTelephonyServicelibrary.jar (delete the original file wherever you found it)
- etc/permissions/privapp-permissions-qti.xml -> /system_root/system/etc/permissions/privapp-permissions-qti.xml (delete the original file wherever you found it)
- etc/permissions/qcrilhook.xml -> /system_root/system/etc/permissions/qcrilhook.xml (delete the original file wherever you found it)
- etc/permissions/qti_permissions.xml -> /system_root/system/etc/permissions/qti_permissions.xml (delete the original file wherever you found it)
- etc/permissions/telephonyservice.xml -> /system_root/system/etc/permissions/telephonyservice.xml (delete the original file wherever you found it)
- priv-app/qcrilmsgtunnel -> /system_root/system/priv-app/qcrilmsgtunnel (replace)

Reboot and profit.

Nice job now maybe the devs can add it to their rom.a little lengthy and out of my league to try

 

[linuxct]

Of course this is not a final solution @gillim74.
But if the mentioned Qcomm apks or jar libs aren't present in the device's vendor partition (which I bet they aren't), the steps of decompiling them, and placing them into vendor is still needed, even for GSI's that include the patch.

What ZUK patch? I got a ZUK Z2 with treble rom and calling is not working.
Where can i get the patches?

Hi
It seems to be a great work.
For me in resurrection remix 8.1 in call audio is working, but music sound over Bluetooth isn't working. Do you've got any ideas?
Please could you share your modified files for in call fix?
Thanks in advance

Thread dead?

No more updates?

This has already been implemented into phh's gsi repo. I have no clue what you expect from this thread anymore.

Thanks, but even as before there are problems with Bluetooth in call and/or audio as before on a couple of devices....

 

[guillermohs9]

Does somebody know if this fix has been included in some ROM? I don't know which ROM to try as GSI on my Razer Phone

IT IS implemented in all new, recently built GSIs. Just try any.

damn, my bluetooth calling still doesn't work on any GSI i try.

Yeah bluetooth calling on Qualcomm devices is still a no-go.
There is a bounty for it: https://github.com/phhusson/treble_experimentations/issues/374

ok, I'm glad I'm not alone. AndroPlus posted in your bounty thread on github as well and he maintains the GSI based build for my device the mi mix 3. for most people bluetooth calling does work with his fix, but for me it does not. i will contribute to the bounty as well.

 

[alkaisr]

nice work bro but can you make a video to explain the way?

I have this problem in the Qualcomm j4 core msm8917
