OnePlus 7T
Hey first off, thanks for this guide. It helped me get back to 11 which I thought couldn't be done as the MSM tool just would not connect.

I ran through the manual guide without issue but got stuck in bootloop. So I reflashed the boot.img and recovery.img again and it worked.
I wanted to relock the bootloader so I could get payment, Netflix, and system updates etc but after I locked it, the phone was bricked I think... Only access to fastboot.
Anybody know where I might have gone wrong locking the bootloader? Fastboot OEM lock was the only command I issued then confirmed on the next screen.

Any help would be appreciated.

If you are trying to relock bootloader just after flashing through msm/fastboot it will probably not boot. You have to flash full OOS update before locking the bootloader.

    Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via recovery (either stock) because is no more needed. The updates will be done on the slot not used for example if you are using slot a the update will be installed on slot b and the slot b will be set as default. If you brick and you are in bootloop how you can restore the rom? You can't with Stock ROM you have, because the zip can be only installed via Update Engine, so what can you do? Flash a stock rom via fastboot. I have extracted all images from the stock zip and i have made a new zip with the Fastboot ROM with a flash-all.bat included. This will work only if your bootloader is unlocked. This will erase all your data and will wipe your internal storage.

    HOW TO FLASH
    This version is only for not branded devices
    Download the zip;
    Unpack the zip in a folder;
    Reboot the OnePlus 7T in fastboot-bootloader mode (Power and volume + and volume-);
    Connect the OnePlus 7T to PC;
    Run flash-all.bat flasher you need;
    Wait until the process end;
    The phone will automatically reboot.

    Unfortunately i have not tested this fastboot rom, i did some tests with an user and nothing else, actually you can't flash from normal fastboot mode system, vendor and product images, you need to use "fastboot reboot fastboot" command to reboot in stock recovery with fastbootd enabled, after that using the fastboot commands you can flash system, vendor and product images.

    If you have any problems with this fastboot rom or you see errors during the script execution, contact me

    After flashing the stock rom it boots up and everything seems fine. When I try to lock the bootloader I get the "Your device is corrupt. It can´t be trusted anymore and will not boot" I've unlocked the bootloader a few times tried reflashing stock rom but everytime I lock the bootloader I get that error message. Any ideas?
    ***Downloaded and Installed the stock rom through the system update in settings menu. Locked the bootloader without issues afterwards***

    So after flashed this fastboot rom, you should local update the original .zip rom to be sure that all partitions are replaced
