Thanks a lot for the needle! If you send me your paypal address as a private message, I'll pay you a beer (or a piece of cake).

I suggest installing Open GApps ARM Android 10 Pico.
I'm not actually sure if I need GApps, and I'm wondering how it worked before. I found that com.google.android.gms was installed in /data/app. Following the error message and the documentation about allowlisting, I crafted a privapp-permissions-google.xml file and placed it in /data/etc/permissions (as the documentation said that it has to live in the same partition). That didn't change anything (maybe it would need to be placed in /system/etc/permissions anyway). I then simply moved away the app from /data/app to /data/tmp, rebooted and now everything's good.

Indeed, if you didn't have it, no need to install it now. I thought it would have fixed the permission problem, but who knows.

No need, I'm happy to help!

I think I found a bug. Yesterday I downloaded the latest version of CARBON-CR-8.0-PAX-RELEASE-z3c-20210420-1310.zip and Open GApps pico + nano.

This is what my installation looked like:

1. Full wipe
2. Installation ROM
3. Wipe cache+dalvik
4. Installation Open Gapps Nano
5. Wipe cache+dalvik

I can't select the sound for alarm, SMS and calls. Just android.process.media crashes and the same goes for Open Gapps Pico.

I have tried installing the system and packages many times, but every time I try to select the ringtone the program crashes. Anyone had such a problem?

    In other news, has anyone got device encryption working on this ROM?
    Bought new in box D5803, unlocked bootloader, flashed:
    • twrp-3.3.1-0.4-z3c.img
    • CARBON-CR-8.0-PAX-RELEASE-z3c-20210520-0416.zip
    • open_gapps-arm-10.0-nano-20210605.zip
    Touched "encrypt phone" and it rebooted twice. Some difference in behavior from the above post is it shows the SONY logo instead of a black screen for the 1st and second boots. Manually reset phone and it booted the third time, encrypted

      CarbonROM is an aftermarket firmware based on the Android Open Source Project. We are dedicated to fast, stable, and feature-filled ROMs, honesty and communication with our users, and openness with our code. We like frequent builds, with the very latest and greatest hardware support and fixes. We strive to not only provide you with the best ROM we can build, but also to give back to the Android community and our fellow developers. For us, this is about creating something we can be proud of and hope you will enjoy.

      Please feel free to look, build, and use our code at CarbonROM's GitHub...

      What is PAX?
      Our release of Android 10, titled CR-8.0, is codenamed PAX after the latin word for peace and Pax, the roman godess for peace.
      PAX provides you with the features you need while keeping the focus on delivering an elegant, smooth, and well polished experience. PAX delivers a set of unique features, like a systemwide font engine that also allows for applying fonts on user apps while supporting user fonts through custom APKs generated on fonts.carbonrom.org. We are confident you'll love it, and there's many more things to discover ;)

      While we make every effort to test these builds as much as possible, we are not responsible for anything that may happen to your device, family, pets, or perception of reality. We ask that you do your part to know your device and know how to recover from problems before you flash! As always, make sure to do backups.

      We spend an astonishing amount of time developing this software. We can't spend much time on XDA as a result, so if you need support, please try the following:

      1) Search. Search, search, search. Yes, you. I don't care how unique or important your question is, it's very likely someone has adressed it already. Especially if you're even close to new at this.
      2) Read our FAQ, which can be found on our website. Carbon FAQ
      3) Ask a question in your device forum. Someone will no doubt try to help you. Warning: this help may come in the form of telling you it's a dumb question that has been asked before. See step 1 - such are the perils of asking questions when you haven't done the research yourself. Android is about helping yourself.
      4) Join our Discord server or Telegram group! There, you can connect with other Carbon users and our developers, and you can get quicker responses to your bug reports. The invite link is right below.

      Remember, every penny you send to us goes right back into the rom. It's used for hardware, server costs, etc - all the things that help us make Carbon better with every release. Your support means the world to us! If you've enjoyed Carbon, please consider a donation toward this goal. Thank you, and we hope you continue to enjoy Carbon!

      Hum this new OP looks interesting.

      And what is this Twitter Post?

      And did someone say May Security Patches?
      My feedback about CR8.0 (weekly build 20200513-0206) with gapps pico, magisk 20.4 and ~75 user apps.
      Using TWRP 3.3.1-z3c-20191212-sar from here
      Xposed (RiRu 20.2 from magisk repo, EdXposed-YAHFA-v0. from here) works without problems (1st screenshot).
      I'm not using internal data encryption because of compatibility problems between ROMs/versions, tired to restore backups each time I flash new ROM.
      About 700MB of RAM free just after boot, with stock launcher.
      Battery drain fast, but my battery is very old, no complain.

      + reliably fast
      + everything works including GPS, BT, calls/data, hotspot and all my apps
      + no problems with audio routing and mic sensitivity
      + camera is ok but I use OpenCamera anyway

      - still no 5ghz wifi in Russia (I use my magisk-patch to fix this, may also help with other regions, try if you meet this bug)
      - ongoing call can be hanged accidentally by double-tap in any place of turned off display (e.g. by cheek) if tap-to-wake feature is active (here is my workaround using Automate tool, works like a charm). I'm not sure if this bug belongs only to my phone or to any z3c, but it was like forever on any AOSP-based ROM, starting with Android 7.
      - broken size for "Aeroplane mode" button/icon in power menu (see 2nd screenshot)
      - ringtone sound become a bit quieter after half a second from start of incoming call
      - overall loudspeakers volume is not loud enough

      Features I'd like to have in this ROM:
      1) choose clock position in statusbar (only at left in CR8.0)
      2) brightness control by sliding in statusbar without opening it
      3) mess up digits on the PIN unlock screen [Carbone Fibers > Buttons > Scramble PIN]
      4) unlock instantly when entering last digit without confirmation
      5) long press power button to turn on/off torch while display turned off [Carbone Fibers > Buttons > Toggle torch]
      6) restrict/disable power menu while phone locked
      7) disable notification panel while phone locked
      8) set minimal time between notifications on per app basis
      9) wake by volume rocker buttons
      10) increasing ringing volume
      11) debugging over network (settings in devs options, absent in CR)
      Most of this stuff available in LOS and AEX roms, but also all (except: 7,10,11, with bugs: 6) can be achieved in CR by using GravityBox xposed module.

      Thank you @Myself5 for continue work with our lovely z3c.
      Due to reports of complications with Google Apps we pulled the PAX builds for Z3 and Z3 Compact. I'm working on a fix and hope to release fixed builds ASAP.

      If you had any weird issues, then that's why. Sorry for that.

      When those builds get released however, they STILL require a clean install over CR-6.1. Dirty flashing does not work.

      We found and fixed the cause. Builds for the Z3 and Z3 Compact are in the process of getting re-released. Sorry for the issues.
      New build uploaded just now has the SetupWizard fixed. The lockscreen bug is getting looked into right now.
