A question, if I want to lock the bootloader again is it possible? i know i have to put the original rom, but what are the other steps?
 
Option 1
When installing the factory (original) version of the ROM using Miflash, check clean all and lock
Option 2
Or you can install the ROM and use a script - clean all
If you are satisfied with the installed ROM, you can lock the bootloader with the command - fastboot oem lock

ATTENTION:
Redmi K40 / 40 Pro
you can lock the bootloader only with Chinese ROM.
Poco F3 / Mi 11X you can lock the bootloader of any Global ROM.

Where can i download mi flash?
 
Is it possible to unlock again after having already unlocked and then relocked?
In other words is unlocking a once-only thing. (Am guessing not, but better to be safe).

Use case is if I want to extend life of a phone by using a technical shop for battery replacement.
 
You can unlock and lock the bootloader repeatedly.
If you unlock the bootloader repeatedly with the same account, the waiting time will not be measured. The bootloader will unlock immediately.

on this POST i want to give a PUBLIC THANK YOU to @gogocar62 for all valuable POSTs! very crucial & important for going deeper on MIUI issues (matters)

but unfortunately due to Xiaomi's decision RULES of LOCK/UNLOCK BootLoader changed again to the WORST
i think this is not clever by them. Xiaomi became great BRAND due to FREE phones and possibilities to choose what you need to do with your OWN phone
of course by your own risk always!!!

if anyone cares or interesting in i could post here a LIST with new measureable times (waiting time) for UnLocking BootLoader
 
This is not a decision of Xiaomi but of the Chinese government and it concerns all brands.
 
did you read this somewhere?
I dreamed of it Xiaomi did it:

thank you! no need to be ironic
but this is very general......as i translated on English because i do not know Chinese! anyone knows? :emoji_smile:
i know in China there is no freedom but empire and dynasty, here they tell us that they supposedly have communism.... not true.
anyway we know that China make everything for the money!!! but on the west side of Earth the Americans have the control (to rule) like they do with Huawei

It's not irony but humor (old Sony ad).;)
The subject in the article is the security of phones against all intrusions.

Edit:
It was a Chinese national who gave me this link, it is a decree from 2022 and its application took place a few months ago.
Even for him it is difficult to obtain authorization to unlock because even if you have the Xiaomi account at the required level and have answered a few technical questions, authorization is not systematically granted and the refusal is without explanation.

All Right we thank him! seems to be general and not specific.
however, among other things, the Unlock may also be included, but maybe they don't want to tell us directly in public :p

as you like humor & fun....
here in Greece we have an expression for Chinese dealers when sells you something and then you run into a problem we say:
- he acts the Chinese (guy) => he plays dumb (feign ignorance)

in our case XIA0MI is doing that against (to) us :(

It's all in this text.
"5. Manufacturers should improve the authority management mechanism for mobile intelligent terminals, improve the security of the operating system, and take technical and management measures to prevent the replacement of the operating system and installation of software of application in the circulation of products."

I have just 2 days ago unlocked my bootloader without any waiting (MIUI 12.5) using this newer version of Mi flash: https://xdaforums.com/t/apply-for-permissions-to-unlock-mi-device-version-7-6-727-43.4650328/.

you have OLD (older) MIUI
is not about which MI flash app you use!
i used the same last version
you are on MIUI 12.5 but if you try MIUI 14 you will see the difficulties

for similar reason i decided to STAY on MIUI 14. so i do not want go to HyperOS without ID (InDonesia) trick......
