I've got a question about the speaker phone. This may not be related to Carbon at all, but I wanted to check.

I never actually used stock OOS when i got my 8T, I just immediately installed Carbon. I used my speaker phone for the first time this evening and man is seems quiet compared to my old 6T.

So i'm curious if anyone here has used the speaker phone on stock OOS before swapping to Carbon and noticed a difference, or if this is just the hardware. Maybe the 6T just has a better speaker than the 8T.

Hi!
I am on Stock OOS right now with my 8t and had a 6t as well before.
As far as I can say now the speaker on OOS is not bad, so I would not say that it was better on the 6t.
Will see how it will be when installing Carbon ROM.
Guess I will do that during the weekend and try it out to see if it is different there than it is on OOS now.

Hi,
Can I flash Carbon ROM using TWRP found here https://forum.xda-developers.com/t/...recovery-project-8t-kebab-2021-09-04.4302449/
The method would be flash TWRP in Fastboot then flash TWRP installer for permanent TWRP. Copy partition data for OOS to both A/B slots. Format data in TWRP. Sideload Carbon reboot recovery, flash Gapps, reboot recovery, flash Magisk 23.
I would be grateful if you could let me know TIA

Might be the easiest to just test it. Be aware that it's untested (and I don't plan on testing it in the future as I see no need for TWRP anymore), but the worst that could happen is that it simply doesn't work, at which point you could just start over.

Hi,
I followed the instructions in the OP, and didn't work for me. I suspect the copy partitions or formatting didn't work as advertised. I then tried the TWRP method I mentioned in a previous post, and it worked perfectly. Carbon ROM installed, rooted and working flawlessly. Thanks to the developers for a great ROM, sent a little something for your great work 👍

anyone else have issues bluetooth streaming to speakers on this rom?

i tried several different speakers and all were pretty choppy and seemed like the range was really bad.

    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 R?
    Our release of Android 11, titled CR-9.0.
    It provides you with the features you need while keeping the focus on delivering an elegant, smooth, and well polished experience. R 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 ;)

    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:
    You should start off with the latest OxygenOS stable build on both slots and then proceed to flash Carbon.

    The easiest way to do that is by installing the latest Version and then copy it by flashing the copy-partitions script made by LineageOS in the recovery. (See install Instructions for the recovery)

    The recommended way to install is using the CarbonRecovery linked below.
    • Download the ROM and optionally GApps, reboot to recovery using
      Code:
      fastboot boot kebab-YYYYMMDD-HHMM-recovery.img
    • Sideload the ROM. (Apply Update -> Apply from ADB -> Connect to PC ->
      Code:
      adb sideload CARBON-CR-9.0-R-WEEKLY-kebab-YYYYMMDD-HHMM.zip
    • Reboot recovery (to switch between slots)
    • Flash GApps/MicroG through sideload like above (optional)
    • Factory reset -> Format data/factory reset (Make sure to have a backup of your data)
    • Done
    Followup builds can be updated through the builtin CarbonDelta Updater or by dirtyflashing.

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!

    Ive so been waiting for this for so long... Big big fan.

    The only thing that could be better than Carbon coming to OnePlus 8T would be if Resurrection Remix came..

    God.. old school rom names.. <3

    already checked and re-downloaded the ROM ..flash from twrp is ok.. only by adb error..is it possible that one of the 2 slots is corrupt?
    Mine installed perfectly when using the rom installer method after extracting the images with the payload dumper. Try that method via fastboot. Also use the Basic NikGapps. That wont give errors while syncing your google accounts (if you desire to use gapps).

    I assume Carbon set it to KB2003.

    Yes. There's no need to write complicated code to set the "correct" prop, neither is it necessary to provide different builds for the individual devices, therefore its just set to the device we also use the blobs from, which is the EU variant. (Same for all OP6-OP9 Pro btw).

    I'm not sure if that's by mistake or intended, but I thought I'd mention it for anyone else with a "Global" 8T that's having trouble passing ctsProfile after installing Carbon. Maybe this will be useful info.

    The Global/EU difference has nothing to do with SafetyNet, it's "not working" on EU phones either. Wee don't actively circumvent SafetyNet, meaning there's no hacks or fixes included. I recommend reading LineageOSs post on SafetyNet to understand why we choose not to "fix"/hack SafetyNet in our official builds.

    Does MTP work for anybody? I can use ADB and fastboot like normal, but my PC doesn't detect the phone in the MTP Mode.
    Works fine for me on multiple machines. Probably a driver issue on the computer side.
