Sensors not working - Unlock and Relock Bootloader - Xiaomi Mi 8 Questions & Answers

Hi,
I have a Xiaomi Mi 8 6/64Gb Global version and last week I updated the ROM for the MIUI 10 Global via OTA.
However, upon doing the update, my camera stopped working as well as other things like compass, gyro, etc.
Anyway, I read some posts around here and I found out that probably the persist.img had any problem and now I have to unlock the bootloader in order to flash the global ROM again to update the persist.img file. I could do it through TWRP, but I think that flashing the full ROM is the same thing correct??
So'm currently waiting for the 360h to pass by in order to do this.
My question is, when I do that, using Miflash, can I do a clean and lock? Or would that cause any problem to my phone?
Thank you in advance

I already read this information, my mi 8 is Global version, what I want to clearify is that it is ok for me to flash the global ROM again, in order to update the persist.img and lock it again
Thanks

I wonder why all Mi 5x users.. even those who have a legit and official rom are affected by this so irritating upgrade. I need to unlock my bootloder asap and this update is killing me! It can be easily identify if a Mi 5x rom is authentic or fake.. so if you have a FAKE rom.. wait for the update to complete and for someone like me who have OFFICIAL and AUTHENTIC rom.. should not have to suffer with this inconvenience! This is not fair, and what Xiaomi doing to us is not right!!
For me my bootloader is unlocked since beginning september, with China Dev 7.9.7.
The single problem it's the vpn requirement.
If you downgrade to this version you can't unlock bootloader ?

[Question] Bootloader opened by seller, unable to close

Hello, I've just recieved a Xiaomi Mi8 phone but in this occasion it comes with unlocked bootloader by seller.
Some users say that in this case there's no way to lock BL, and in case of brick you won't be able to flash in EDL mode.
I'd like to know if there's a way to lock it and later unlock it with my own Xiaomi account ID, and leave phone like a brand new one from factory.
Thanks in advance.

Ez, just flash the phone with China Stable or China Developer ROM via Miflash , choose Clean and Lock, done
Choose clean and lock with any China miui ROM. ONLY CHINA ROM. Upgrade to a higher version only (Don't go from miui 10 to miui 9). Beware of this and you will avoid bricking your mi 8

Did you actually tested that? Or just a theory (I know that it has sense but pretty risky to try)
Thanks !
Thanks but I'll try after someone else has done it with success. I hope it works, maybe that way my Xiaomi ID could be linked to the phone.

It is a fact. The bricking only arise due to Xiaomi's implementation of a new policy, whereby they prevent relocking of a China variant of their phone when the global rom is installed. Your Mi 8 will only brick if it is not the global version but you flash global miui and try to lock. With that said however, I am not liable if you bricked your phone and you should indeed proceed modifying your phone with caution. All the best and feel free to ask if you have any questions!
PS. Since android oreo, Google has also implemented another policy which prevents rollback to older android versions. However, due to Xiaomi's (lack of) implementation of this, you can brick your phone when you downgrade for Miui 10 to Miui 9 for example. So always keep this in mind as it is a thing to watch out for now.
Thanks for the explanation, maybe there's a new Xiaomi policy trying to avoid selling phones for China market to other countries, that should be with Global versions.

Has anyone tried the procedure?
I want to know too. I think installing a Chinese version, you can block the bootloader. Then you unlock with your normal My Account, to avoid possible problems.
Some say that if you lock bootloader even with china ROM you'll get a brick. I'm not sure of that but I prefer to try when someone has done the procces with success.
One more problem are the 720h Xiaomi makes you wait for unlocking, sometimes more than 1000h. Very bad policy for old Mi Fans after years with Xiaomi devices.

read this. this guy did what he was supposed to do and ended up with a brick. dont relock your phone just because someone says so.
i am still looking for some one to explain why official way is better. the only case i found this to be true so far was if you manage to screw up and lock your chinese phone on global rom (or the other way around, same story). in that case, you are way better off because you can go to fastboot and unlock your phone, and after that it should boot. please share any info you have on this topic, but please also explain how and why. thanks
Thanks, then I'll keep it opened using Xiaomi.eu weekly ROM.

Mi9 Transparent Edition question

Hi Guys!
I already searched on this forum and couldn't reach a conclusion.
Never had a Xiaomi device berefore. I bought a Mi9 transparent edition from China, It will arrive next week, but I would like to know:
Can I flash global ROM? It has Chinese ROM.
Can I flash Mi9 standard AOSP based ROMs?
Thanks.

Yes you can, since it is Chinese version it already has bootloader unlocked, so it's even easier to install whatever you want

Don't lock bootloader with global ROM or you will hard brick your device.

Ok, so can I really flash xiaomi.eu/ROS/Globe without any risk? I am afraid of bricking it, I don't think I have warranty support on my country since it is a chinese version phone and I saw that the it is almost unbrickable.

Question Is there a way to flash from MIUI China to MIUI Global without unlocking the bootloader

Hi, so i recently got the new Mi 11 and stupid me, i didn't check what version it was and when i booted the phone up, i realized that i got the Chinese version. Due to me having no patience waiting the 7 days to unlock it i cant really use anything. Can someone help me
You have to wait
It is possible - but I do not recommend - you can in EDL mode bypassing xiaomi authorization, you may brick the phone
But to do it hi has to have athorized acout or someone who has It.

The guy on Telegram group who fixed my bricked mi 11 buy flashing through edl told me that he cannot flash a Global rom to my mi 10 with locked bootloader and CN rom. If he cannot do it for mi 10 it is unlikely that he can do it for mi 11.
