Rename ur boot image file to twrp.img
And then in adb type
1. fastboot devices (see if you are connected or not... If connected type 2nd command)
2. fastboot flash recovery twrp.img
After that by using power up button navigate to RECOVERY MOD and press power key
DONE
U will be running twrp recovery
flash magisk via recovery to maintain root
Enjoy

download latest twrp.img from official website. place it in adb fastboot tool folder. then open command prompt widows in same folder. reboot you device into fastboot mode and connect to pc now run the following command
fastboot erase recovery
fastboot flash recovery "recovery file name"

3. Copy the magisk_patched.img and past in the ADB folder.
4. In ADB floder open command prompt and phone connect to PC.

5. Check current slot of the device :fastboot getvar current-slot

6. Type fastboot flash boot magisk_patched.img into terminal window.(type fastboot flash boot_a(b) magisk_patched.img but my phone can't.)

Question Root OXYGEN OS 13 MT2111_11_F.11 ?

Is there any way we can root MT2111_11_F.11 because for me fastboot appears to be missing as when i try volume down and power it just keeps on restarting after a see the fastboot screen for 0.01secs.
I tried using adb reboot bootloader as well but didn't work.
You should use adb reboot fastboot instead. Note that this mode doesn't allow to unlock bootloader if it is locked. But if bootloader was unlocked earlier, you may use flash command to flash patched boot.img
Code:
fastboot flash boot boot.img
go to github magisk, get apk install it on your phone, download your Full OTA, extract it via payload.bin extractor and take out boot.img then patch boot.img using magisk and do fastboot flash boot magiskpatchedboot.img
Original boot.img for oos f11 to patch

Button combination = Fastboot Logo flashes for a split second, Phone instantly restarts to system, no access to bootloader therefore impossible to use flash commands
adb from system > reboot to bootloader = exact same as above.
Not bootloader, but userspace fastboot (fastbootd) mode. The command is
Code:
adb reboot fastboot
