Official Miui 9 stable after bootloader unlock

Hi . . . I am new in redmi 4 but i know all about roms flashing and unlocking bootloader because i am tried a lot of roms on my previous mobile . . I want to know is possible to flash official miui fastboot update after unlocking bootloader on redmi 4 ?? And after flashed fastboot update is bootloader will be locked again ??
Yeah, you can flash official miui with fastboot. MI flash app have an option to re-lock the bootloader or simply flash the rom without touch anything. You can see this option at the bottom right of the program
Also can happen that you flash the rom and accidentally lock the bootloader, because this option is marked by default. In this case you only need to unlock the bootloader again with Xiaomi's program, don't need to wait 72 hours. This already happened to me.
With locked bootloader I prefers xiaomitool for upgrading or downgrading any miui rom.
Use xiaomitool it is safest tool
Tnx for the replys i got it

Question Flashed Indonesian Rom in Sweetin and relocked Bootloader😥😫

My friend flashed Indonesian fastboot Rom in indian RN10 Pro Max and locked the Bootloader, now he is trying to add acount and device to unlock it again but if fails everytime.
An error shows "Couldn't add. Device basic data verification failed"
Please see the attached screenshot.
Do you have any clue how to solve the issue?
you were should use only format data not all & relock.
There is three .bat orders:
one with erasing user data.
one with keep user data.
one with format and relock.
In your case you have to unlock it again.
Can't unlock, can't add account and device. Always shows the error mentioned in the post.
I had to abandon my previous xiaomi phone just for this reason. Accidentally locked the bootloader and couldn't unlock it ever. "The find device storage corrupted, your device is unsafe now".
Couldn't add miui account.

You did the same? I mean flashed another region's rom and locked bootloader?
My friend told me that he did the same in his Redmi Note 8 and then re-unlocked and flashed stock regions's rom, it was fine for redmi 8 so he did this in RN10 Pro too.

I actually did worse. I was on non-miui Rom then flashed the Fastboot without unticking the lock option. Guess what though the sensors of my MI5 is all okay nothing works due to wrong persist file.

Could you please share how to flash? since bootloader is locked cant flash anything.
Maybe you did not get my point, we are stuck in another region's ROM with locked bootloader.
Try find Xiaomi repair support center and tell them to help you flash official Indian ROM for you.
You can boot into the system, and the device said it's locked and secure, so it's not hard brick. Should be fine for them to help out, if the warranty is covered under the policy.
Be prepared for data loss, so you need to backup what you want to keep.
Don't tell them you flash a wrong region ROM. Just say the phone seems a bit strange, so want them to help clean flash and update official latest ROM.

You can try flashing stock with mi flash tool by rebooting to bootloader. Recovery ROM might work even with locked bootloader

forum.xda-developers.com
Never lock the bootloader when flashing a non original ROM. You may now need to find someone who can perform an edl level flash. Just look at other posts, they do mention who to contact but it will cost a few dollars.

Your case is more easy than was mine. Just reflash the original ROM, unlock, and flash the global.
Cant flash original ? how did you flash it ?
I just found a guy fixed it in EDL mode remotely (Paid service )

are you sure you can't flash?
You said your phone can't boot, get into fastboot, download the oficial fastbook rom to your smart, and just re-flash using the cable
its locked bootloader !
i relocked by mistake .. and mi account is not mine so i cant unlock again
I wont send this post if i have unlocked one
EDL flash then I'm afraid
Same problem here.
Anyone have a contact who can help me, $$.
Thank you
Edl flashing is easy (if we are talking about the same thing), you just need an original rom and the software. But yeah, not sure if that exists for the Ultra out there..
Software is MiFlash or something like that IIRC.

Question Change MIUI region version and lock bootloader

Hi,
I have a Chinese Mi 11 Ultra. I have used the Mi flash tool to flash the EU based version of the ROM but I did not lock the bootloader. This has brought in some problems, such as GPay not working, which I dont really mind but the Mcdonalds app with the coupons also wont start up.
I am wondering, if I get the EU miui13 fastboot rom (original from Xiaomi), and use the mi flash tool to flash it, can I also lock the bootloader? Will it be fine or will it brick the device?
I believe this answers your question: https://c.mi.com/thread-2584760-1-1.html
The TLDR is you can only lock bootloader in China devices if you flash the China ROM. Some people claim to have successfully flashed China ROMs on Glogal phones and locked the bootloader without any issues but you'd be taking a risk.

do not close bootloader do not do it
you only close bootloader if your in CN version
i had to pay 70 $ to bring my mi 11 ultra from dead, after installing miui 13 EEA version and locked bootloader using flashmiui

Hi, Thanks for the answer. Guess I cant lock the bootloader then. Do you know of anyway to get the services working that require a locked bootloader? Iirc it's to so with safetynet but I cant remember if it was possible to overcome this with magisk. I havent been on the rooting scene for a long time so I didnt follow any updates

Yes. According to Xiaomi, it is recommended to unlock the BOOTLOADER but if you don't want to, the device will not be damaged:
Steps:
Put the device in FastBoot mode
Install XiaoMi Tool on your PC and configure it ( https://www.xiaomitool.com/V2/latest )
Choose option "Device locked. I want to unlock it"
You choose which device is yours
And let the app guide you
