Is Mi Unlock really needed to unlock bootloader?

I have searched for a very long time how to unlock the bootloader to this phone. What I came across was the proper way to unlock the bootloader, using Xiaomi's unlocking service. This way tends to take around a week to actually unlock your phone. I am far too impatient for this and have yet to find a better option to get my phone's bootloader unlocked. Is there any better way to do this?

No, you'll have to be patient.

For some reason, mine came unlocked. I bought it from the Xiaomi Ali express store.

I want to buy this phone but am wary because of my past experience with Huawei's locked bootloader, and their requirement to go through them to unlock; which they discontinued right after I bought the damn thing!
This required a payment (about $25 iirc) to a third party in order to get an unlock code.
Is this something I should be worried about with Xiaomi phones?

This shouldn't be a concern for now. Xiaomi isn't planning to restrict unlocking the bootloader. Another thing you should consider is that Redmi note 8 pro gets easily bricked by flashing custom twrp, magisk, etc. but it's not easily recovered as it requires xiaomi authorised account.

Thanks for that info! I'm thinking I'll go with my other phone choice, as I like to mess around with all that stuff, and custom ROMs.

Can someone explain how is it possible that after unlocking the phone and rooting,it still shows my phone is locked and secured?

You are using the stock rom, right? This is a false alarm. If you can flash modules and edit system files you are rooted for sure.

That's a serious red flag. Make sure you flash every possible firmware from the stocks here...
But if I were you, I'd return it and get it retail properly. Ali Express is notorious for vendors that put spyware and other ****e on their phones prior to shipping.
I got a proper Redmi Note 5 Plus (Vince) once, and retail was supposed to have a locked bootloader in the same fashion as this phone. On Redmi 5, however, there was an even cooler known problem where they would keep people's bootloaders locked, but flash malicious firmware using a testbed by taking the phones apart. So people would receive their Redmi 5's from Ali Express bugged and they would have to wait out those weeks to unlock it and flash clean images.
On an unrelated note, I did use an exploit on that MIUI version by creating two accounts, logging off, signing off, I don't remember. But I unlocked the bootloader the day I got my Vince. I'm not sure if this will work anymore. Not that I needed to. Again, I would never get a phone of Ali Express.

I don't know about spyware but they mainly unlock the bootloader on china variant to flash the global rom and sell it as a global variant. Later the user receives an update notification and installs the update and voala you get your device bricked.

Yes, once in a while they do it just for the sake of putting on a "better" ROM. Some of those Ali Express Note 5's reportedly came with even beta ROMs.
I'm saying just to exercise caution, is all. But a different ROM that would receive the wrong OTA sounds just as bad. I've never even thought about that scenario...

you can use fastboot rom from the guide section and flash that in fastbootd. its pretty easy to do. my 7t used to be on global but i returned to tmobile stock rom just for the google feed on the left instead of shelf. Before asking questions, just read a couple of pages back to avoid spamming the same questions others have had.

Should I back up some files in case some issues happen? Such as finger print doesn't work when the bootloader relocked? Because of I saw in other some pages in OnePlus 8 series.

i mean i havent backed up anything in relation to persist since ive also seen how to the fingerprint scanner is affected on the oneplus 8. i have relocked my bootloader on my 7t and the only thing not working is ota. i have no other issues besides that. fingerprint works fine after custom rom flashing and switching between global and tmobile stock rom. so id say you are fine since the msmtool does restore everything on the 7t. if you care about widevine level it'll return to stock if you go back to the locked bootloader state. also never re lock the bootloader when running anything custom to avoid issues(brick/bootloop).

I got problem today, but I'm not sure what's going on. I got my sim card in oneplus 7T and the device has been unlocked, the reason I said unlocked because of advance option show this device has been unlocked and able to use any of carriers, but there's no signal at all in my device. I switched the sim card to other phone and it's working, so I put my friend's sim card in oneplus 7T and it's working. Now I don't real understand why it's not working. When I got home and the device is working again.
Do you know anything about it?

how to convert oneplus 7t tmobile to international without unloking bootloader ?

hi, i want to convert my 7t from tmobile to international but without uncloking the bootloader.
i have found some threads about it here, but they are a bit confusing since they are showing how to do everything, like rooting, unlcloking and all these stuffs together and i just want to do the conversion to international without uncloking the bootloader, so if someone could help me with that i will appreciate it.
because i do not want to brick my phone i just want to do it right
the current model i have now is this (oneplus 7t HD1907 build number 10.0.12HD63CB)

Question i heard something about bootloader un/relocking

is it true that relocking a unlocked bootloader erases everything, but you can re-unlock it ever again on xiaomi devices?

Hi,
I am new Poco F3 owner,
I got the Amazon black Friday deal £50 off,
my variant has 8gb of rom & 256gb of ram, all this for £269.00p,
what an Amazing price and also comes with 2 years warranty here in the UK.
I have been a LG users for many years, using the (G2, G4, and for now a G7) .
I have installed many custom roms on these devices over the last 8 years.
Unlocking/locking there bootloader have been relatively straight forward.
I asking the same question that I am sure has been asked many times before,
once my 7 days are up and i have unlocked my bootloader and i then lock it again,
but then further down the line i decide to unlock it again,
do i have to wait another 7 pointless days.
I'm loving the new poco F3, apart from the firmware is a bit restrictive,
hence why I'm unlocking the bootloader.
What a great community the F3 has , long may it continue,
regards,
Johnr64

No, you only have to wait the first time.
This waiting time is not so pointless as it seems however. It is there to discourage a.o. the many traders flashing (often fake) 'global' roms on Chinese phones and selling them as genuine global models for extra profit. So in the end it's only for your protection, because flashing roms invalidates warranty.

so just to clarify there is no limit on unlocking and relocking this phone right?

xiaomi unlock tool its infinite dont worry, but be extreme cautious when you are locking your bootloader make sure your are in your right stock rom and dont forget to unlock again when you are going to flash custom roms and recovery

To lock the bootloader you can simply use "fastboot oem lock" in fastboot mode. Note that doing so will (obviously) factory reset your phone.

in the event where i lose my phone an unlocked bootloader can bypass any password protection if they have the knowledge right?
is there any way to protect the phone from this?

If you mean screen lock, yes they can bypass it. But they cannot get into your banking apps or others which have their own passwords.
If you are really keen on it, just lock the bootloader.

Question 2023 T-Mobile vs Unlocked OP 9 Pro

Question:
I own a T-Mobile account. Just went through major drama w/ amazon seller, a T-Mobile phone that wouldn't unlock because it wasn't paid off, and more. Never mind that.... sending it back.
I want to know if I can buy a non-US and/or unlocked OP 9 Pro and still have it work with my T-Mobile sim?
I want in the end, ideally, to have a OP 9 Pro running the very latest Oxygen OS/updates and have it be rooted. But again, w/ a T-Mobile sim.
Advice? Has anyone else faced this?

Don't send back.... Using the T-Mobile app and chat you can be over complementary and ask for full unlock and should be able to get it that way. Option 2 is to use a modded MSM tool to convert to Global, unlock bootloader, us a modded Glo to TMO MSM TOOL to get back to TMO firmware and update. But recommend to stay away from A13 for now

Was your recommendation to avoid updating based on the trouble that DaveImagery was having with achieving root? If so, I can assure you rooting the T-Mobile android 13 update is no different than rooting the global or eu firmware, aside from having to always temp boot TWRP rather than actually install it. TWRP acts up sometimes but it works. I think he was either having a problem with the driver's, USB port, or cable, or something went wrong when he pulled the boot image via MSM tool.

If you got the factory unlocked one then sure, it'll work with a t-mobile sim. The question is whether it will be 100% compatible with t-mobile's network or not. I don't know the answer to that question. It's worth noting however that the T-Mobile variant is slower to get updates, and just got Android 13 this month. If I'm not mistaken, the global and EU variants got Android 13 last year. This fall/winter the other variants will probably be getting android 14, while the t-mobile variant waits until next spring.

T-Mobile updates are slower because they are more refined and sometimes include multiple updates in one update. That is why they are slower..

I decided to stay with what I got, esp. as the seller also (belatedly) included the original 65w fast charger. I did a bit of whining. So now I'm trying to get my employer to leverage t-mobile into unlocking the phone, since we've been w/ them a long time and it technically is my employers' phone. (They appreciate my geek interests and are willing.)
If I can get it unlocked, the next questions will be about just how flexible T-Mobile's sim will be with various rooted Oxygen OS's.
I used to root all the time.... my Samsung Note 4 (dang I loved that phone), my OnePlus 2 (rebuilt from 2 broken ones... by me!), and so on. But Samsung's Note 9 wasn't rootable (I didn't have the Exynos version). So I got stuck. This time I bought the OnePlus 9 Pro intentionally in order to play w/ rooting again.
But the whole thing has gotten more interesting. TWRP... does it still work and do the awesome backups / restores of multiple different systems on the same phone? And Magisk.... sheesh... so much I don't know.

If you have no luck through TMO with unlocking the bootloader, let me know. There is another way to do that.

How exactly would that work? I've read that using the T-Mobile->EU MSM allows you to unlock the bootloader without an unlock token, but wouldn't using another MSM to go back to T-Mobile firmware re-lock the bootloader? Would the fact that it's already been unlocked previously allow it to be unlocked again without a token, even after flashing back to the T-Mobile firmware? Mine came sim unlocked and didn't have any trouble getting an unlock token so I never tried the workaround and I've just flashed the unlock token every time.

I have a modded TMO to Glo and a modded Glo to TMO.....I have used it before....

So it is in fact possible to skip waiting for a token. You have to use MSM to convert to EU then you're free to do whatever since the bootloader is now unlocked? Am I understanding? I'd like to personally flash Lineage as soon as I'm unlocked, will the above process work for me?

I believe you. What I'm saying is that according to what I have read, every time you use a MSM tool it locks the bootloader. So you convert to eu, and unlock the bootloader without an unlock token, because this specific firmware is unique in its ability to be unlocked without a token. Then you flash the T-Mobile firmware with another MSM which locks the bootloader all over again, and now you are once again on T-Mobile firmware with a locked bootloader and no unlock token. My questions are:
1) Does the fact that you previously unlocked the bootloader permanently do away with the need for an unlock token, even after you MSM back to T-Mobile firmware and re-lock the bootloader?
2) If so then how do you unlock the bootloader the second time after you MSM back to T-Mobile firmware? Do you repeat the same procedure you did on the EU firmware, or do you just run the "fastboot oem unlock" command from now on?

The way it is done with the modded MSM Tool to go from Global back to TMO it does not lock the bootloader. Can't explain why, but it doesn't. A pure TMO MSM Tool will relock the bootloader. Been there and done both ways.

In a few days I will do it again just to triple check the procedures and create the necessary modded MSM Tool zip files to share.

Another way to get unlock token is by booting to bootloader and run the command to get unlock code. Copy the long list of numbers along with IMEI and serial number and email OnePlus support with the information stating the TMO unlock token website is not working for you and they will generate a token for you. I had to do that when my first token quit working....
