IMS registration failed

[Glusniffer]

@jb-essential @gibsson First off, thank you for keeping the ph-1 alive!

I've built AOSP successfully and found out that there is a /vendor/bin/imsrcsd is failing to start because it's referencing a symbol that are no longer available. It's also missing some apps which can be pulled from the Stock android 10 package.

A few things I've done so far:

• create a shim library to fix the symbol issue
• patchelf /vendor/bin/imsrcsd
• patchelf /vendor/lib/lib-imsrcs-v2.so
• patchelf /vendor/lib/lib-uceservice.so
• patchelf /vendor/lib64/lib-imsrcs-v2.so
• patchelf /vendor/lib64/lib-uceservice.so
• repackage vendor image
• add /system/app/ims (pulled from stock Android 10)
• add /system/app/uceShimService (pulled from stock Android 10)
• use root to resolve some selinux issue because of the shim

If either of you or someone from the community can provide some insight on how to troubleshoot "E Diag_Lib: [IMS_FATAL]| 2051 |ims_qmi_register_client : Failed". I/the community would really appreciate it. I believe this bit is the only major issue left for this Android 11 AOSP build.

I've tried this on both r3 and r8 with the same result.

Thanks!

I've been seeing that ims_qmi_register_client: failed error for a year and a half or so, on stock or custom... it doesn't seem to actually hinder anything in my experience despite the error sounding like it's quite problematic

[Glusniffer]

Are you using it on a carrier that doesn't support VoLTE, Wifi Calling, etc? IMS is required for these features to work. T-Mobile is not going to support any device that doesn't have VoLTE support next year.

[itz63c]

Im on Verizon, VoLTE is fine. friend of mine is on TMo, both WFC and VoLTE work fine. another buddy on ATT with VoLTE working fine despite the presence of that error.

If that's the case, this AOSP build is missing something else then. VoLTE doesn't work for me, the phone will drop to HSPA to make/receive calls.

Have you tried building the A11_r3+ rom and running it on your device yet?

[Glusniffer]

found this issue, #9, in the closed section. I'll give this a go and will provide an update later this week.

[Glusniffer]

So I recompile libbase with the method mentioned in #9 which wasn't necessary. It looks like in Android 11, /vendor/bin/imsrcsd doesn't use the library at /system/lib64/libbase.so. It's actually using /system/system_ext/apex/com.android.vndk.v29/lib64/libbase.so. The artifacts in here are google prebuilt. I replaced libbase.so with the files pulled from stock essential rom (/system/lib64/vndk-sp-29/libbase.so). This solved the missing symbol for imsrcsd. But I am greeted with a sigsegv null pointer dereference for /vendor/bin/imsdatadaemon now. I tried to replacing libutils.so with the file from essential stock as well but that didn't fix it this time.

Any pointer on how to fix this would be appreciated.

PHHusson has updated his Android 11 GSI, which now includes " some preliminary version of IMS stuff".
See: https://github.com/phhusson/treble_e...ses/tag/v300.g

In the sources there is a folder for the Essential PH-1 that includes files addressing ims.
See: \vendor-HAL\Essential
