Guys can anybody help i have OnePlus 8t. 1st i downloaded the rom zip 6.2gb and then 8t support zip after that i paste the 8t support package into rom folder and click on kebab flasher bat file and my phone boot into the Qualcomm crash dump mode. Can anybody please tell me what i am doing wrong
To clarify for everyone:
IT DOESNT WORK ON THE 8T RIGHT NOW AT ALL. The 8t has different partition sizes and this installer is designed to work on 8 and 8 pro, so it will fail on the 8t every time because of partition sizes. Maybe it'll be updated but as of right now 8t isn't working. It will always go to crashdump

    Hey there, 8t user here. Wanted to try this, but I was wondering, is there any way to go back to stock firmware if I change my mind?

    Of course. Flash TWRP, take a full nandroid backup of your OOS and then flash anything you want. You can always go back rather quickly.

    Here You go guys! This phone is a nightmare to develop for. But we will do it!

    @ProtoDeVNan0 could you take a look at ColorOS from the Chinese Version of the 8 and 8 Pro? Would be cool if you could port ColorOS to the Global Version :D
    Unfortunately only OP8 got it for now and dynamic ColorOS has issue with data creation but as soon as Chinese 8 Pro gets it, I'm sure that will be possible.

    Anyway, new MIUI build is now available, last one had black screen issues. This one I managed to use for around 2 hours without a single display issue.

    Also this build has experimental 8/8T Support with dedicated vendor for both of these devices.

    Changelog

    Added improved support for OnePlus8 and OnePlus8T
    Fixed Black Screen Issue (tested for 2 hours without black screen happening)
    Switched to China Dev with GApps
    Added Addons folder with working GCam + PlayStore
    AOD seems to be working for some themes now
    Added additional improvements for A/B (may/may not affect anything as logs don't show much)

    Make sure to read README.txt after extracting the ROM for instructions and notes!
    Support Package is supposed to be extracted into same directory as main ROM.

    Enjoy! Next update will be out with new security patch as I'm busy with other devices + my personal work + OneUI 3.1 for 8 Pro which has 95% of hardware working already.

    People moan that there's not enough ROMs on forums, and here we have people moaning that a ROM has been released?? Not a Magisk ROM, an actual ROM??

    Give the man a thumbs up don't take the piss.

    Well done to the OP for your work. It's appreciated by most.
