    I have never experince any problem with my previous phones when it comes to install custom roms.

    But with Oneplus 6......
    After so many times, I am near to give up

    When Im in adb(while in bootloader/fastboot on the phone) and "fastboot boot" the twrp image I wipe everything; after that I can't copy files to the internal memory via file manager in windows.... So I need to use an Usb memery to install the files from; and it take alot of tries to even access the usb memory.
    I have tried using sideload also.

    But after reboot I always get into either bootlaoder again or qualcom crash message. If click to access recovery from bootlader I come to the Liange Recovery?! Not twrp and still I can't reboot to the OS....
    The rom I want to install is the Linage Official 17.1.

    Here is a few screenshots from how the result can be(different from try to try)


    What should I do in order to install this rom?

    if you have never flashed a custom recovery and custom rom on a A/B partition device, you are likely to get into trouble.
    follow guides available on xda on how to successfully flash roms on A/B partitioned devices.
