please i need opinion from Expert ...

No, there is no risk at all, and also in the flashing too, if you're still censored you can choose to lock your bootloader again after flashing, and u're all good.

Relock after flashing ?!!! . You may mean after stock rom flash while after flashing Custom Rom no more relock bootloader .
In all cases for the banking app you can use magisk to hide (if you have) your rooted device

Hello,
I bought a 64gb version throw gearbest and they installed a vendors version 7.3.14.0.0 not oficial rom. With defeats the purpose of the bootloader being locked.
I want to install the original miui 8 china or miui 8 from xiaomi.eu.
If I unlock my bootloader by submitting the request to xiaomi what I lose? What are the disavantages?
Does the fingerprint reader works on a bootloader unlocked phone with official miui 8 china?
Does it work with xiaomi.eu rom?
What are the features that cease to work with an unlocked bootloader with these two roms?
If I install xiaomi.eu rom without unlock the bootloader using Doom Slayer method I must not update by OTA or I will brick it, right?
And oficial miui 8 can I update by OTA?
Sorry for these questions but is my first xiaomi with locked bootloader and don't want to screw up by not knowing the consequences of each method?
Thanks in advance

The fingerprint will work. But Find phone will not work and it will not be secure. But your phone will be less secure like if gets stolen anybody can flash firmware and you will be loser. With find my phone nobody could even flash firmware . I have got permission within 2 days for unlocking but i have not done but i have flashed chinese firmware by using miflash. the link is here http://en.miui.com/thread-326039-1-1.html. it is very safe that way.

Security is not about flashing, is about protecting your data. Encryption makes phone more secure, not locked bootloader. We have ways to flash whatever we want with locked bootloader... how about that? Do you still fil secure?
Thank you both,
@seking for what I could understand this is the xiaomi.eu rom with even more stuff, right?
Do you have the helium version?
For that rom you just need the miflash to flash the rom via fastboot, right?
This is different from the Doom Slayer method because with it we fastboot the TWRP recovery and then use it to flash the xiaomi rom.
@nijel8, that is my question also the locked bootloader doesn't add security, gearbest flashed a custom rom even with it locked, so the security reason isn't a valid one.
Partition encrypting is only available when the bootloader is locked? If so that is one feature that is gone with unlocking.
If one unlock the bootloader can later lock it again?
With the bootloader locked we can't use miflash tool to flash fastboot rom, right? Only using EDL, and even then from what I could understand the system and data partition need to be formatted and that removes the encryption...
I just want to get rid of a rom that I don't know what is it and install a oficial rom or a rom from good sources like xiaomi.eu
After replace my rom can I update it by OTA or after I must update only by fastboot ot TWRP?
Thanks again
Bootloader status has nothing to do with encryption. Encryption always is a user option in any ROM... Not sure about MIUI though b/c they enforce encryption on both system and userdata partitions in ramdisk fstab so no user choice as far as I know. And yes... You can always lock bootloader back but will loose your data in process.
Not going to answer the second set of questions (see my signature ) not b/c I don't know but b/c never done it myself so yeah...
mi max is comparatively new phone. there are notnmany roms. development still new. therefore be careful of what you flash. for hardbrick solving we have to open the back cover which is risky. i have taken the safe mthod of not unlocking it. i flashed the rom on the locked rom with miflash via EDL. one can always flash the official rom through twrp and you will be safe.
Thanks a lot you two.
Trying to get the most information before doing something wrong.
Don't worry... Mi Max poves to be die hard phone...
Hello guys! I wanna know if I can lock my bootl back is I flash a custom recovery and rom. Can I lock my bootloader and come back to MIUI? Can I use MI flash with option clean and lock with custom recovery? Or I need stock?

Miflash will replace custom recovery

And on top of this the answer is that yes if you use mi flash clean and lock option then technically you have warranty back since the phone is locked.
However if the device is compromised to a point where you cannot flash then there's no way to get warranty back.
Tbh the risk is worth it

There's barely a risk with an unlocked bootloader, the real problem arises when you ruin everything with a locked bootloader and you can't even flash anything.

That's actually incredibly true for Xiaomi phones.
Seems the majority of issues arise from LB phones that brick and can't be flashed without test point (voiding warranty anyway)
If you have the rights to unlock the bootloader, then even if you keep locked and it bricks, you can unlock and flash a rom again.
In fact even if you don't want a custom rom or root, asking to be able to unlock bootloader is must, just in case.
i was wondering if i unlocked the bootloader and installed a custom rom i`m not willing to change soon, can i lock the bootloader again while i have this rom?

Certainly you can if you are prepared for a bricked device later. I mean, it is not advisable to lock the bootloader if you have a custom ROM since any issues arise later, you will not be able to solve them. In addition, even if you manage to unlock the bootloader again in such a scenario, you will lose all your data including files, photos, videos etc.
If you properly sign the firmware, you don't even have to unlock the bootloader, see https://forum.xda-developers.com/oneplus-3t/how-to/guide-custom-kernels-roms-recoveries-t3572525
I have sent the unlock request to xiaomi so need to wait for a week to unlock the phone. I have found so many bugs on 12.5.2 specially battery drain so fast. I would like to know once is unlocked the bootloader can I downgrade from 12.5.2.0(RRGEUXM) to V10.4.5.0.PGGEUXM? If it can be done with MI flash tool and i want to use some banking apps can they be used or need to be lock again the bootloader? will I be able to unlock the bootloader in the future if needed again? Sorry for the questions I have no much idea . I really appreciate the help and support of the community. Thank you my anti number is 1
1. I think yes, with data wipe (select flash_all). Unlocking bootloader will also wipe your data so do it once and never look back. I haven't tested that. But undoable without data wipe, that's for sure. ROM region doesn't matter unless if you are planning to relock the bootloader
2. Depends on the apps. Some of them can be fooled by magisk hide, some of them even detect bootloader lock status (but how? idk). Just test your apps in every bootloader lock status scenarios, and you will find your answer (not only for banking apps. some apps will be locked out if it detects root/tampered boot)
3. No need to worry about anti rollback lock. It virtually doesn't exist in this device

Firstly, you shouldn't re-lock your device while you are running something "custom" on it.
And in case you switched from Chinese to Global, no matter that it is a stock one, neither.
You should completely return to stock and re-lock device either through fastboot commands or using the option "Flash all and lock" through Mi Flash tool.
technically it is possible to relock the bl on some phones and some roms (graphene os for example)
the process is ... let's say complicated. and risky.
as subway said, no do not try to relock if you want to run a custom rom.
Thanx Dear,
i found the problem, its in Magisk, i disable it and every thing goes normal
