OnePlus Nord corrupt device (lock bootloder)

I just rooted the oneplus nord with magisk and then locked the bootloder and im stuck with the prompt that my device is corrupted please help me.
also i wiped internal storage and tried to unlock bootloder but it didnt worked
someone please help

Try to access the recovery by pressing volume up and power button when starting! Then choose english and choose to wipe everything! This could work if you did not flash twrp

If you have locked bootloader and unlocking from fastboot doesn't work there is no way to recover your device without and EDL flash. Please contact OnePlus Support for further information

You can find the EDL tool here https://forum.xda-developers.com/oneplus-nord/how-to/opnord-unbrick-tool-to-restore-device-t4148415. Use it to unbrick your device

Why you want to lock bootloader ? Install custom ROM is need unlock bootloader. Why you first unblock it and then block it. Officially rmx1971 can run until android 11, with custom ROM it can install new version. What you need do is. Go to bootloader download my TWRP if you are on Android 11 and flash it
Fastboot flash recovery recovery_3.6.2_11.img from there you have to install custom ROM.
