  • Using RCS with Google Messages on GrapheneOS

Syberkonda Got this working. I'm on a Pixel 7 Pro and used this specific variant of the old apk: https://www.apkmirror.com/apk/google-inc/messenger-google-inc/messenger-google-inc-20220214_00_rc02-release/messages-messages-android_20220214_00_rc02-phone_dynamic-3-android-apk-download/download/?key=b28cfb181ec0dccfe74d743d5ab3724ec2c40474&forcebaseapk=true Also had to install Activity Launcher https://play.google.com/store/apps/details?id=de.szalkowski.activitylauncher . I do not have Carrier Services installed. For Google Play I just have Network enabled. For messages I have all but location enabled. After following the instructions on the reddit thread and using the Verizon link provided in this post I got it working then immediately updated the app and rcs still worked. When I go into settings though it says it's disabled so not sure what's going on there. Will post back if it gets disabled and fails to activate. Not sure if others have tried this without carrier services installed

    Hello everyone! I had made an account to report my findings. It seems my RCS on Google Messages stopped working around the same time as most people in this thread. I had followed a couple people's suggestions here and no avail. I decided to give Syberkonda's post a try and it actually worked! I followed the post pretty much to a 'T' but instead of grabbing the APK from apkmirror, I used Aurora store and the version code that's listed under the app variants. I matched my CPU architecture, went with the nodpi, openbeta build; version code: 52051140. After that, I followed the steps normally.

    I am using a Pixel 7 on AT&T with the latest build. So instead of the Verizon ACS URL, I used "https://rcs-acs-att-us.jibe.google.com". It connected pretty much instantly and I was able to update the app with Aurora afterwards and still keep RCS connected.

    Edit: I forgot to mention, I do not have carrier services installed.

      Guys, my RCS hasn't disconnected nor dropped out. I disabled Carrier Services today to see if that will make a difference. The APK from APK Mirror is technically signed by Google and would have been an existing version at that time.

        It says "Connected" in green text followed by my phone number.

        Activated successfully on Sunday on Verizon with the beta APK method. Got unregistered on Wednesday. Repeating the process worked, but now I'm concerned this will be a frequent thing.

        Activated through install from Google Play store, over mobile data and VPN turned off.

          Mine keeps unregistering every 3 days or so and I have to repeat the process. It seems to me like we need to find a way to manually change the ACS URL. Unfortunately newer Google Messages versions don't seem to have an option to do this in activity launcher. I've been looking for a way to change the ACS URL in debug settings to no avail.

          I wonder if there's a way to permanently assign an ACS URL via something like adb

          Does anyone know if something changed about Graphene around November/December that might impact this?

          I've done all the troubleshooting including a factory reset and a new SIM card. I get RCS within moments with this SIM on another stock OS phone.

            *I've also tried turning on auto verification of phone numbers within my Google account. That's something that helped earlier in the year to get RCS.

            This time around the status of auto verification doesn't change from "pending". Makes me think Google isn't seeing something it wants to see in order to do it's verification.

              If you are using a DNS service like NextDNS or ControlD, try adding your RCS ACS URL to the whitelist to ensure that it isn't being blocked.

                Is that with the older apk?

                I may go that route, but it'd be nice to get this sorted out with the current version. It's not my preference to run old software if I can help it.

                  It worked 👍.Just installed the version of Messages you sent. I don't think I accomplished anything with Activity Launcher so it didn't play any role. The version of Messages you sent did it all.

                  Unregistered again after 3 days, so that's at least consistent.
