Using the standard XIAOMI batch unlock tool, WHILE you click UNLOCK or after issuing
Code:
fastboot oem lock
,
keep volume down pressed!

Then from a shell, type:
fastboot -u continue

Hmm if you're saying we can re-lock the bootloader without wiping data then there might be a way to keep root and get the bootloader locked... Any videos on the correct setup?

no.. you won't be able to boot an unmodified bootloader....
but you can keep the data partition at least... check something, then reunlock...

Then whats the point if phone wont Boot?.
Its my understanding when you install a rom stock or not, the partition has to be formatted for it to encrypt the new install, so its not gonna boot anyway unless ya wipe data, defeats the purpose for me ha ha, i was hopeful i could unlock and boot back to wiui without having to reinstall lol.

Example:
you have a rooted phone with modified bootloader, recovery and everything...
you want to try out an original rom with original locks like in a freshly bought phone
but you don't want to lose applications and data.

Yoou reflash the stock rom without deleting the data partition, and you relock the bootloader. Usually doing so it wipes the data partition too...

It's just a way for testers and hackers to go back and forth without wiping anything.

    NO. data won't wipe. but you won't be able to boot a tampered system.. all you will be able to do is to keep the data partition
    tampered system huh
