[OnePlus 7T Pro (Regular & McLaren) ROMs & Dev.] Myself5:
​

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 ;)

Disclaimer:

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.

Support:

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) 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.

3) 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

After the first flash you'll be able to use the builtin updater to profit from seamless updates when updating Carbon.
