If you unlocked it once and didn't flash the stock ROM or relocked it again then there's no need to unlock it again as it's already unlocked

do we need to unlock bootloader to install mm roms

hello guys,
I am new to the xda developers and a bit confused about the procedure of flashing new mm rom.. want to experiance the stock android 6.0 as we are still stuck with the kitkat 4.4.
while visiting the cm13 thread i saw in the instructions that we need to unlock the bootloader in order to flash any of the mm roms,
I have already reuested on miui for unlocking my bootloader but came to know that it may take around 15 days,,
feeling a bit confused about the whole process,
awaiting your help,
sorry for the immature querry.

xiaomi mi3
The Mi3 and Mi4 are not "stuck on 4.4" for a very long time now, and the Mi3 and Mi4 never had a locked bootloader.

ohh thanks for clearing my confussion bro....and i was talking about the official miui rom which is still based on 4.4.
so that means i can just follow the normal procedure and flash any of the mm roms..?
To get new partition scheme, install latest china dev rom (MM) with MiFlash.

After this you can install TWRP and any rom.

You can either install the Miui MM chinese-dev ROM, or search for "cancro CM Baseband" and follow instructions, that will repartition your device, update baseband and install latest twrp. After that you can flash any ROM. Personally i use Ressurection Remix MM v5.6.9 and i'm very satisfied

Read before flashing any Roms based on the official cm trees

If you have flashed any Roms based on sathosh's sir's trees I.e unofficial RR,Aicp,Aokp and cm. Your bootloaders have been updated to mm bootloaders which are based on a leaked build. This bootloader is not officially supported by cm trees, thus if you flash a ROM when you are in this bootloader that is based on official cm trees,then you will get bugs like settings and security FC.
How do I fix this?
The fix is simple. Backup all your stuff.
1) If you have unlocked officially.
Then flash a miui recovery rom. Boot into fastboot, open mi unlock and unlock your bootloader.
2)If you have unlocked unofficially
Then flash via fastboot with patched emmc appsboot file. And type fastboot OEM unlock-go .
Do this if some bugs persist then post on the respective ROMs thread.
You will never walk alone
Keep it brah
Much needed guide. Thanks

Tell me if i am wrong
I am officially unlocked
Flashed unofficial rrremix 8th june build afterwards unlocked bootloader via mi unlock tool
Yesterday made a full wipe flashed unofficial rr remix 20th june built which i guess is based on custom cm sources as after flashing i checked if the bootloader was locked thru adb and it wasnt but i did not have any app fcs or any problems with the rom
Conclusion if i am right with my statement
If u r unlocked officially flash any rom based on miui sources after flashing unlock bootloader again if ur bootloader is locked
Then u can flash any rom with cm13 based kernel without flashing miui rom
Correct me if i am wrong
I have done it and the latest unofficial rr build built on 20th june is based on cm13 sources not on miui sources
My way will work only if u r officially unlocked

If you have unlocked your bootloader officially , when you install cm13 roms with locked bootloader you can directly unlock them using Mi-unlock tool . But if you have unlocked your bootloader unofficially and after installing a rom if your bootloader is locked then, you would have to flash miui rom via MiFlash tool then unlock the bootloader using that rom(so you will loose your cm13 rom).

I was only refering to op that if u officislly unlocked and flashed a custom rom with miui resources and want to flash a custom rom with cm13 sources u dont have to flash miui rom again u can only unlock the boot loader on exsisting rom and flash a cm13 sources based custom rom and it will run bugless

Even Santhosh's CM can be unlocked via Mi Flash without going back to MIUI ROM.
You people have'nt realized the existence of two bootloaders. Unlocking is diffrent. both bootloaders can be unlocked. But Roms based on official cm trees onlu support the lollipop boot loader and not the bootloader from the leaked build.

I was on AOSP 5.1, backed up using twrp Alka before flashing Santhosh CM13. Then I wiped and flashed Bliss, wiped and flashed unofficial Resurrection Remix. Can I just flash a Xiaomi.eu ROM through twrp and unlock it through MiUnlock after and that's it?

Man cm based bootloaders need not be unlocked they r originally unlocked only the miui based bootloaders r locked all the latwst roms except i guess by santosh m sir r miui based so u know better only issue is that all latest roms r nightly if u flash updates only do a clean install and when ur rim boots up set up as new device and dont restore frm back up

Man. Punctuation. Please.
Is the new RR unofficial ROM based on cm source or xiaomi?
OK, so if I am understanding OP correctly, what we need to do is re-unlock our bootloaders and then do a clean install of the rom containing the CM-based bootloader.
No , once you install a ROM for example cm13 by Mr Santosh , then your bootloader will be automatically locked , therefore you need to unlock the bootloader and then install cm based bootloader ROMs for example RR official .

Yes. That's what I meant.
If we took a backup using Alka TWRP while our bootloaders were unlocked before flashing a rom based on Santosh's trees, can we just restore that backup and then flash a CM based bootloader ROM?
Currently I am on RR (Unofficial 20th June Build). I unlocked my bootloader officially. Now i am trying to unlock bootloader again with MiUnlocker but it gets stuck at 99% with unknown error. If I want to switch to another rom (based on CM), should I require unlocked bootloader??

Hii... I'm unlocked officially and rooted with xposed installed. Not custom kernel or rom. I read on miui forum tht installing mm causes bootloop. How can I ensure it doesn't. Thanks.

Can we update the ROM via ota officially?

Any updates coming?

I'm really liking the Mi Mix but concerned about security with the device. Is the OEM planning on updating the latest security patch or move to Nougat? I'm on a April security patch and using the latest Global Rom. Thanks!

If you want nougat you can try the global beta
(Im using epic rom based on miui beta 7.6.8 nougat with may security patch)
Do I need an unlocked bootloader to apply the beta? Oh, and is it pretty stable?

You dont need an unlocked bootloader, there is a flash guide in the beta download section.
I prefer the global stable, in my experience it was faster and more persistent than the beta, And if you will regret flashing the beta you will have a hard time going back to stable (unlocking bootloader and flashing twrp and downloading all your apps again...).
But if you want to flash the beta you should unlock your bootloader and flash twrp so when you do flash the beta you will have a backup (backup in twrp before flashing the beta) of your latest stable miui.
Its your choice

Okay, so I really don't want to mess with all of that if the stable version is better. I'm just hoping we get a OTA update soon. I used to have the Honor Note 8 and they had the Nougat update back in March and some updates since then. Hope the Mi Mix keeps getting supported.

Hmm. I was under impression that to flash ANY other ROM rather than factory one, you need to unlock bootloader. To go from original factory Chinese rom to stable Global ROM - do you need to unlock bootloader or no?

Just checking if there are any updates with the Global Rom, such as Nougat or even a security update? I'm currently back to my S8+ until I hear about an update to the Global Rom. I'm curious to see the level of support when you go with this company.
Android 7.0 is in beta testing, so should be coming out soon as a stable/global rom.
I can't handle my S8+ and want to start using my Mi Mix again. Should I be concerned that it's still on Marshmallow with the Android security patch from April?

My advise, stay on stable. Currently all MIUI ROM sucks and buggy. Literally Only difference you will notice in Pie is more bugs and issues.

I use the 8.10.11 after using the 10.02 stable. The Camera Quality is better and Android Auto works fine now.
Flashing the beta is only possible via Fastboot.
I didnt noticed a lot of Bugs in the daily usage.
Beta Pie working fine for me. Using dialy from first day relese.

Thanks for your reply. You are 100% right. After some research I realized that it is NOT possible to flash the Developer ROM with a locked bootloader. I even tried older Developer ROM's which were still based on Android 8.1 because the newer versions were based on Android 9.0. A few days ago, the Pocophone and the Mi A2 allowed me to switch from Stable to Developer and back, without any problems, simply by flashing the .zip via the stock Updater app.

It is not possible, you need to unlock the bootloader AND install custom recovery. Xiaomi phones aren't always the easiest to return to stock should you actually decide to do it and then decide to return to stock.
The official stable release is rumored to arrive in November, possibly even December, so it might be a good idea to wait a little longer.
