Read step 7 and step 20.
Honestly the biggest drawback is that generally no L1 support after unlock, but in this phone that doesn't happen, so I would say No drawback at all
Ok thanks. I was thinking of trying miui but I didn't wanna wait 7 days once I decide miui isn't for me. I will unlock as soon as I get the phone

No, you must wait 7 days to unlock after you submit the request to unlock bootloader. So you still need to bear with MIUI for at least 7 days.
There's no shortcut (yet).
Most banking apps will not work with unlocked bootloader. This apps consider unlocked bootloader as a root of the system, so a lack of security.

The warranty will be voided if bootloader unlocked

Yes that is true but it's still possible to pass safety nets but as long safety nets are passing u should still be able to use banking apps even if running on custom ROM

This is not always true.
Xiaomi/Redmi/Poco in many countries still have warranty after bootloader unlocked.
Check the local Xiaomi/Redmi/Poco policy yourself.

Firstly is SafetyNet check. This is the first thing for banking apps.
Some ROMs did not pass SafetyNet out of the box and they have to use Magisk and modules to make them pass. This kind of ROMs mostly will have issues with bank apps.
To sum up:
Bootloader unlock: you can use bank apps, but sometimes not.
Root: you can use bank apps with some adjustments, but sometimes not.
ROMs: you can use bank apps, but sometimes not without the help of Root.
Try and error, life is just like this.

That is not totally correct either.
There are many cases that people had installed custom ROM and bricked their phone, but Xiaomi still give free warranty within the warranty deadline.
If you installed custom ROM and need Xiaomi warranty, simply return to MIUI and you still get Xiaomi warranty within deadline, if the policy said so.

Warranty good but even if it does get voided I will still unlock bootloader anyway because of custom ROM and stuff but it's cool that warranty does not get voided after unlocking bootloader

As I said, some bank apps can work. If ur bank app does not work, then the only way to use it is to root the ROM using Magisk (and some other specific magisk modules have to be installed if installing magisk only does not do the trick).

Thank you so much but you cannot explain me step by step because I'm not sure the right way.
Pretty sure with Samsungs once you trip Knox there's no way back. Made that mistake with Tab S4

Not sure what exactly you did.
Do you mean you just toggled "allow OEM unlock" in Developer Settings? If so, just go back to Developer Setting and toggle it back off.
Do you mean you booted into Download mode and confirmed you wanted to unlock the bootloader? If that's the case, I'm not sure. Maybe boot into Download mode again and see if there's an option to relock it?
Either way, unlocking the bootloader should not have tripped Knox or prevented you from using Knox services.
Now. If you unlocked the bootloader and flashed TWRP or any custom firmware, then Knox is tripped and that is irreversible. If that's the case you'll never be able to use Knox services on that device again.

I think once you unlock it trips Knox as it considers itself "vulnerable" then.

I used to think that as well; however, I've been told by a few Exynos users that unlocking bootloader itself will not trip Knox. I did some research last night and the site's I found agreed. Knox is not tripped until a custom recovery or firmware is flashed.
I'm NOT saying I'm 100% right about that. I have a US Snapdragon and haven't unlocked a bootloader since the S7Edge (I bought a Exynos model of that phone from eBay). I'm just researching and trying to help the OP best I can. It sounds like he tripped Knox and that can't be reversed, but won't know until we find out exactly what he did.

Yea SD here, he might have done something more than, instead of just toggling.
If I use ADB to remove bloatware on the F3, will I lose my warranty? Is the Xiaomi ADB official (from Xiaomi)? Do I also lose my warranty if I unlock the bootloader and install a custom ROM? If not does Xiaomi say so on their website? What is the difference between using ADB and just deleting them manually? Thanks!
You will not use your warranty by using adb to remove bloatware. However you do waver your warranty by unlocking the bootloader to put a custom ROM on it. However you can theoretically still get a replacement despite this wavering of a warranty

You should be find. I have never had a Xiaomi and so didn't know how supportive they are. The official advice by Xiaomi is here:
What do you need to know about unlocking?
First and foremost you can only unlock your own device. This means the unlocking tool you downloaded must be logged in with the same Mi account on your device. One Mi account could only unlock one device within 30 days
Isn't locking bootloader against Mi's 'geek' spirit?
Locking bootloader is aimed to provide a better user experience, which we've been trying to do the whole time. In the meantime, we've provided an unlocking tool for senior users who know their ways around flashing and tweaking their devices.
The unlocking procedure will need Internet access to get the unlocking password. Also, the Mi Account logged in on the Mi phone and the unlocking tool needs to be the same. Otherwise, the unlocking request will be denied. This will ensure that ill-intentioned people will not get access to your personal data.

And that's where I come in.
I sent my Xiaomi Mi 9T Pro as a guarantee having had the precotion of flashing the global rom and re-locking the bootloader (I had a problem with my antenna, I received nothing).
They supported my Mi 9T Pro without any problem

Firstly don't consider locking the bootloader once you've done any ROM modifications.
Secondly unlocking the bootloader doesn't actually void the warranty on a Xiaomi device so you should be fine. However it's up to the discretion of Xiaomi (i.e if you brick the device then that's your fault)

You have to check Xiaomi/Redmi/Poco warranty policy in your country yourself. The regulation varies between countries and regions.
In many countries and regions Xiaomi/Redmi/Poco still have warranty coverage after bootloader unlocked, but there's some exceptions. Check it yourself on the official website.

Just go buy the phone. It is worth it. Xiaomi EU is just as good as the newest chinese rom, and even somehow little better. So you kinda get the best.

Relock bootloader with Xiaomi.eu ROM that was based on China ROM in your Global phone is dangerous.
You can try if you dare to risk it on your Poco F3. You have been warned.
The principle is: do not lock bootloader.

Flash stock ROM back into phone, which makes phone looks identical to just after bootloader unlocked, so it's can still be under warranty, if you were able to flash it back.
There are exceptions that will still void warranty, read the policy yourself.
I want to update my phone but it just doesn't work because apparently xiaomi is blocking the update to android 11, I dont get new updates and can't update manually either. I even contacted Xiaomi support and all they said was "you should go to the store where you bought the product." lmao
I know unlocking the bootloader and installing a rom would work, but this way my bank app would be unusable for me, so I can't do it.
Is there any way to flash my device to a new version without unlocking bootloader?

Just unlock bootloader then lock it again by flash fastboot rom (Clean all and lock option). And just a few bank apps that not work for unlocked bootloader.

Also, my bank app is one of those that doesn't work with unlocked bootloader.

It just got error if you try to lock bootloader with some other regions. Example: China phone with other roms. If you lock bootloader with same varient, it will be like a new phone with updated.
And almost bank apps problem is safetynet pass and root related, not unlocked bootloader. Go search online or find other group to check your bank app work or not. You can also join rmn8p group on Telegram with some useful guide over there.

That is to say that with so many details in your question, it is difficult to answer precisely but if your device is Chinese only root and magisk will allow this.

downgrade or installing rom,No?
AFAIK no other way than to flash Magisk, enable Zygisk and use Module "SafetyNet-Fix".
If you don't use Root, in Magisk you can set to auto-deny all Root-requests.
So if I installed the EEA stock fastboot rom, I would not pass the Google Play store certification and safetynet if I leave the bootloader unlocked? Just to be sure.
This is the first I've read about this. I was thinking maybe go back to stock for a change.
Can I unlock the bootloader again in the future if I install the rom with clean all and lock?
Yes, simply unlocking the bootloader will fail SafetyNet.
Yes, you can unlock the Bootloader again, at any time.
yes you can unlock again, instantly, you wont need to wait 7 days
