    Hey everyone.

    I'm writing from my Oneplus 8 pro but it involves my 5T. It's old (obviously) and I'm trying to install TWRP but it refuses because it says device state locked. No idea why. Oem is open, bootloader is unlocked and USB debugging is unlocked. Any help would be massively appreciated. Thanks

    Ps: it's international version

    Try booting twrp directly with command fastboot boot recovery.img

    Once you are on twrp recovery copy the recovery.img to internal storage and flash it via twrp. 👍🏼

    Its failing to install TWRP because bootloader is locked. Try passing the unlock command again. Check the latest tutorials to get the correct command.
