Does this support MEMC/Motion Smoothing? I searched the thread but didn't find anything.

So... I'm super curious... Has anyone had any problems setting app op permissions? I can't modify any of them for any app at all. Does anyone have any suggestions?

Is it possible to have OnePlus switch work with this rom? Also, my phone is showing IN2023 instead of IN2025. Is that normal with this rom?

Thank you

How do I get "latest OOS" in both slots?

Dear Myself5,

Even after MSM Download Tool, I have OOS only in the slot A, and the slot B is not booting even to fastbootd -- "fastboot reboot fastboot" results in Quallcomm Crash Dump.
There are fastboot OOS ROMs here on XDA, but to flash it into the slot B one still needs working "fastbootd".

    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 goddess 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 system-wide 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 addressed 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.

    Install Instructions:
    Other than previously provided ROMs, this is using the "normal" method of providing a flashable zip.
    You should start off with the latest OxygenOS on both slots and then proceed to flash Carbon.
    You must at least use TWRP 3.4.0-1 by @mauronofrio to flash this.

    • Download the ROM and optionally GApps, reboot to TWRP.
    • Flash the ROM
    • Reboot recovery (to switch between slots)
    • Flash GApps (optional)
    • Format /data*
    • Done

    *As TWRP is currently unable to format /data you can use fastboot to format
    fastboot -w
    It appears that fastboot on Windows has issues with the wipe command. In that case use both of the following commands
    fastboot erase userdata
    fastboot erase metadata

    Download Mirror

    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!

    New Build

    Just uploaded CARBON-CR-8.0-PAX-UNOFFICIAL-instantnoodlep-20200730-1536. Has some testing changes to the Telephony stack as I discovered occasional telephony crashes when reconnecting to WiFi with VoWiFi enabled. Also still has the VoLTE/VoWiFi icons (which are now merged) and a few changes for GooglePlay Security updates.

    Still working on the Google Apps not flashing properly at times.

    Also as the question seemed to come up: Sooner or later the OP8 Pro will become officially supported on CarbonROM. However, before that happens there's still a few things that need to be sorted out (e.G. GApps survival on OTA updates and a few other things) so I can't provide any ETAs on when that would happen.
    CARBON-CR-8.0-PAX-UNOFFICIAL-instantnoodlep-20200713-1912 has been uploaded as a new update.

    Contains July ASBs and a VoLTE/VoWiFi icons for test, opinions welcome.
    I updated the flashing instruction in OP to reflect on various ways to format /data as TWRP is currently not able to do so.

    You can either use fastboot to format
    or if that fails (which has been reported of being an issue with fastboot on Windows) flash THIS userdata.img using
    fastboot flash userdata userdata.img

    EDIT: As of TWRP 3.4.0-1 by @mauronofrio you can flash Carbon with that just fine.
    I just saw the news.

    Very nice. :love:
    CR9 thread with install instructions and everything will be coming later today :)
