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 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 using either fastboot or the userdata.img below*
  • Done
It might be worth noting that I only added ~500MB of free space for GApps installation. OpenGapps nano, for example, leave around 105MB of free space available, so bigger GApps packages, like stock or full may not work. I might adjust that in the future.

*As TWRP is currently unable to format /data you can either use fastboot to format

fastboot -w

or, if that fails (which WILL HAPPEN if you use Windows) flash THIS userdata.img using

fastboot flash userdata userdata.img

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!

If coming by from another rom, do I just format data first and then flash Carbon or should I reflash OOS on both slots again?

@Myself5, you say to reboot twrp in between for flashing gapps to another partition. Do I read it right? Or do we need to flash the rom again to another partition after rebooting twrp

Only reboot in recovery to change slot, and then flash gapps

so for me this doesnt work and i dunno what i am doing wrong.

flashed oos to both slots, flashed your twrp, flashed rom, reboot to recovery and device doesnt decrypt so no gapps to install. booting up ends in sticking at carbon boot logo.
