How to Relock Bootloader Galaxy A51

[uliek01]

Hi, for those of you who have already unlocked the boot loader before, and if one day you change your mind to lock the bootloader again, here's how (remember, This will wipe your data again!)
- Shut down your device.
- attach the data cable to the PC or laptop
- Press the volume up & volume down buttons simultaneously
- plug the data cable into the device
- Wait until the warning screen appears (download mode)
- long press volume up
- then press the volume up again to confirm
- the device will restart and delete all your data.
Done! your Galaxy A51 locked again

hahaha, the truth is that does not happen, I do not know what mobile you have but it is not this A51, since I have tried that and it has never come out, so stop inventing things, which are not true, and if your information is correct, do a video and show, thanks.

locked again

and this is obvious. and if not, you can use the search. (topic nearby, first post, explanation under the button..) https://forum.xda-developers.com/galaxy-a51/how-to/a51-aosp-vanilla-firmware-pure-android-t4093821 but it doesn’t matter and your message is not superfluous. !!!But what is very important!!! - you forgot to say that if you have custom firmware, kernel and/or other things, blocking the bootloader can make a brick out of your device. well if the service helps. Or maybe not.
I beg you, think over your instructions well, a lot of people come here who are not well versed in the issue, they may suffer from bad/not complete instructions. with respect. have a nice day.
p.s. My post may be no read. please update yours.
