[Q] Relocking Bootloader after installing Cyanogenmod?

Hey gang, trying to make sure I won't run into any nasty surprises before I attempt this, so;
I want to install the Unofficial Cyanogenmod ROM for the Mi 5, move away from Miui - but I also want to regain Android Pay functionality (and a few other apps I'd like to use that require a 'secure' device). For that, as far as I know, I need to relock the bootloader. So basically I'm looking to have my device that is:-
• Rooted
• Running custom ROM
• Custom recovery
• Locked Bootloader (or at least Android Pay functionality)
Installing the ROM and keeping the recovery updated and working isn't a problem, but I just want to make sure that I won't bugger something up when playing around with the bootloader. I've never had a device that's needed a bootloader unlock before, so I'm very tentative around the whole idea.
Is there anything that I need to know about relocking? Such as specific quirks with the device (I've read people have found themselves stuck in boot loops after locking) and if it's even possible to do so with a different ROM installed.
Thanks in advance!

Don't lock bootloader again, usually it causes issues(been there, done that).
But Android Pay doesn't require a locked bootloader, just unmodified system.

Now that I have the X522 rooted...

I've rooted a few phones before, but I never really got into all the custom stuff. Where should I start to see what all I can do? I mostly use the phone for games so I dont know if there's a custom kernel/governor for that or what...

I found something called LineageOS and installed it, but now I don't have full root access anymore...anyone know the deal with that?

You need to turn it on under Settings-> Developer Options

bootloader

Is it possible to unlock?

At this moment, no.

You will know as it'll be reported here very early. There are some third party companies that do it. Some are cheaper than others.
For the moment, there is nothing..
Sucks I know

I asked this before on another similar thread and didn't get a response. Is it possible to dump the bootloader from either an unlocked or locked phone to analyse it for potential vulnerabilities either in how it handles the unlock code, or more generally that would allow a user to soft-mod unlock the phone? I know for the 5th, 7th, and 9th gen Fire 7 tablets exploits were found in the LK part of the bootloader which eventually allowed for a customised version of TWRP to be flashed onto the devices, and later LineageOS. If we could dump the current Huawei bootloader surely we could try to find if there are any similar exploits?

I am found metod but it needs mrt dongle((

Tbh custom roms aren't really important anymore. Google is already ruining android everytime a new update comes around, like the overlay feature that was introduced in oreo but then removed for no reason.
Besides EMUI is already optimised for the chip so, again, no reason for custom roms and/or rooting (unless you want to remove bloatware but that can be solved via ADB)

Bootloader Xiaomi Redmi 9

Hello to everyone reading this, wish you all the best in the New Year.. Now let's get to the problem I have.. I'm using Brave as my browser and I am sure most of you are familiar with Brave Ads, well they don't work on my phone.. While duckduckgo-ing through I stumbled on possible reason why it may not work, the said reason was unlocked bootloader.. It was suggested to download SafetyNet test and check if everything is as it should be. To my surprise my bootloader was unlocked (I double checked via developer options since Xiaomi offers information on that there as well) but the issue is I never flashed any ROM or Firmware nor anything similar, it's stock as it can be from the store.. Now that I elaborated the best I can (Since my native language is not English) I need to ask 3 questions as stupid as the may sound.
1. Is it possible that bootloader unlocked by itself or some shady app?
2. Does that lock icon below front camera unlocks bootloader by tapping when you turn on the phone? (Since it was locked before and now its not)
3. Is there a way I can lock it without using PC and adb tools?
Thank you for your answers and time, much appreciated!
PS: I would add pictures if needed but since I didn't tamper with the phone nor change anything in developer options I doubt it's of any help.

To lock the bootloader in mi you need to flash the stock rom and if you only need to pass the safety net checks install magisk canary and it's not actually possible to unlock an mi device without the authentication of Xiaomi so it can not unlock by itself as far as I know. Are you totally sure you or someone in your family or friends didn't unlock the bootloader because if not this may be a dangerous exploit used by a shady app and should be reported to Xiaomi now.

Not a single soul have a access to my phone, and if they did they sure as hell don't know hot to flash custom roms or unlock bootloader.. So it might be some shady app.. But how would I check and see if that is true?
PS: And about magisk canary I don't see it in google play store, but I suppose that is apk for rooted phones? The issue is my phone is not rooted if that is the case.

Question Consequences installing custom ROM [SPES|SPESN]

Hello,
I would like to list the consequences of the changes when installing a custom rom on the redmi note 11 (spes/n).
In your opinion, what causes the following changes on our phone
This is some responses I can give after testing myself
1/ Unlock bootloader
Erase all your data
The unlock icon appears on the top of starting logo
2/ Install custom Recovery
Nothing have happened
3/ Install custom Rom (for me Evolution X)
First install : You will have to erase all your data
Upgrade : Nothing should happen
4/ Root
Maybe Unauthorizing Bank apk ?

Hi Darkspirit66,
Whilst I am not at the Custom Rom'ing stages yet with this phone, too new for me to tinker with this one... I'll just have to settle with me other phones for messing around with for now...
However I am glad you've raised these points. Whilst I've asked this before in another thread, its good to have clear answers...
Whilst most of the earlier questions, I kinda of expected. Some kind of message/logo at booting stage to announce it's unlocked/modified. I believe this is standard in pretty much all phones, one way or another.
Unlocking Bootloader/Flashing, again.... erasing of the data is standard practice again.
The bit that most concerns me... Is there any tell tale signs of after unlocking/rooting....? I've come from a mainly Samsung background. In the early phones, you simply ran "TriangleAway" and bob's ya uncle... no one is any of the wiser. Under new models, once ya trip the ole Knox, there's no going back. Permanent visible sign of tinkering, and security and bank apps will never work again without tricks.
So, if one was to unlock the Bootloader, root, rom and then change their mind and go back to stock. Will all the banking apps continue to work, or does it alter it for good....? I believe once unlocked and with custom recovery, its best to flash stock with TWRP as you get to keep the unlock but can flash stock and custom as much as you like without any triggers...??
Cheers, Lister

Hi LOS
Rooting the phone results in the problem with banking applications.
If you decide to unroot (it's possible) and reinstall a stock rom the apks should work again. (To confirm)

You can always hide root with magisk and keep your phone rooted also with banking apps ;-)
