Hi, thanks for reading,
Ok so my 6903 z1, i've downgraded it to .534, rooted it, installed dualrecovery and am sitting here wondering where to go next.
I wouldn't mind unlocking the bootloader so that I could install other kernels such as pimped kernel. But reading the dualrecovery thread it seems that it is only if you are using the original kernel. So my main question is, what should i do next?
use recovery to flash a zip of a new rom then unlock bootloader then flash a supported recovery?
or should i unlock bootloader now and then new rom etc? (was concerned about the camera issue unlocking the bootloader on <4.3 roms.... will it be "fixed" if i was running on a newer "flashed via recovery" ROM?)
any help is appreciated as I don't want to bugger up the phone like i somehow managed to last time i tried all this (had the IMEI disappearing issue)
If you want to unlock the boot, there is was no need to downgrade to root
Just backup your TA, unlock the boot, flash a custom kernel of your choice then flash away
oh ok. well i've done it now. although I've just checked my service menu
First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the dialler and enter *#*#7378423#*#* to access the service menu.
In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

and it says bootloader unlock allowed: No
So i'm guessing I randomly cannot unlock it anyway? (any reason why if that is the case?)

If that it saying then no way around to unlock your bootloader. BTW, stock kernel isn't that bad and with root you will be able to customize your room and get some tweeks.

so if i cannot unlock bootloader, does that mean i wont be able to use custom roms like Paranoid android etc which run off of CM and presumably a CM kernel?
and is it worth trying to unlock the bootloader in flashtool anyway just to see?
What options/next steps do i have then if i cant flash a custom rom due to not being able to use a different kernel?
Guess i can flash a modified stock rom and thats about it?

Unfortunately No, anything based on Custom Kernels you cannot install. Everything based on Stock Kernel you can Install, even Custom Roms.
oh bloody hell. ok so i'm now stuck in a sony logo boot loop after installing romaur v8 and installing the kernel (561) which it told me to.
any ideas what to do? guessing i'm going to have to flash the old 4.2.2 rom from scratch again
ok so now i'm back to .534 [nut] and rooted. any tips on where to go next so that i dont get stuck in another bootloop???

I thought the romaur rom Was based on stock. Ho hum. Installed the pure stock one and it was OK thanks.
In Android developement thread all roms are based on stock - in original Android developement they are based on pure android.
Bootlooping is mostly caused when flashing wrong bootbundle/kernel.

@punkt, nice your avatar, that is what I call HD..lol..
My frustration level is super high with this brand new Mi Mix I bought from a US reseller that came unlocked with the official latest global rom version. Before I decide to return it, can anyone please tell me a simple way to relock the bootloader so I can download Netflix and use this device like normal? I can't even get the Mi PC suite to recognize its connected. Very annoying!
do you try mi flash? there are options clean install dirty and clean relock install
No, do I need too flash the rom again with the tool to relock or is there an option to just lock the bootloader only? Will I still get Global Rom updates after relocking? Am I able to unlock in the future since it's already been unlocked once by the reseller? Thanks for your earlier response! I'm just not that good with all the modification stuff.
No You cant relock without clean install anda yes You will recieve otas
And for The re unlock You have to need a code if your seller unlock it then You have to get xiaomi unlock permission again once You recieve The code with your acc You can lock relock unlock anytime You want

Thanks! So can I just do a clean reinstall directly from the phone and will it automatically lock for me? I apologize - I'm not really technical with this stuff. I'm on the latest Global Rom that's on the official site. I don't want to change my rom or root in any manner. I just want keep it the way it is and simply lock the bootloader. I have read some other guides about flashing and downloading a whole bunch of drivers and changing settings on my PC to get it to work. Isn't there any easier way of doing this? I want it to work like if I just bought it at a store and allow me to set it up like have with my S8+.
Then install mı flash and fasboot rom of your choise global stable or global beta then close The phone and open pressing w power button and wolume down button at The same time once You ses The tinker bunny (fasboot mode pic) connect your phone with a cable and install with mı flash of your choise of rom and ext its very easy en.miui.com download section You can fallow The steps there its tooooo easy You can spor
And no You can not lock your bootloader anyother way
Thanks! I got it reflashed and locked! When I searched the Play Store, Netflix showed up right away! Appreciate the help... It was super easy!

Hi Egentreri,
I am surprised to read by your reply; I thought the bootloader could be relocked using a fastboot command. I have bought a Mi6 a few days ago and it came with an EU rom. I decided to flash the Global Rom using the regular update tool from the rom itself, but unfortunately TWRP was installed, something I hadn't checked... and I bricked the phone. I managed to reflash the stock recovery (in chinese) in fastboot and I the phone some how booted again and I could reflash the rom from the update tool and this seems to have flashed a new stock recovery as it is now in english?
My bootloader is still unlocked, but I guess I could use the fastboot command to relock the phone as I now have a stock recovery along with a stock Global Rom? What do you think?
Thanks,
Alex

In my non expert opinion and little experience flashing som custom roms and then going back to official (beta and stable), and back again to custom with twrp recovery and all... Sure and easiest method for going to any of the official roms and having the bootloader relocked is to flash chosen rom with fastboot update: for the Mix: http://en.miui.com/a-234.html
That way, which I understand is what @gman901 did, with the same package you get back to locked bootloader, stock recovery, etc.
I got my Mix unlocked also, which I didn't mind as I quickly rooted and went to try some fantastic custom roms. But the first weeks, when going back and forth and trying this and that, at some point I wanted to go back to vanilla official global stable, and from there to global developer. To do the first step from custom rom only fastboot update worked.
Hope this helps!
I bought a used xz2 and I just found out that it was running stock aosp pie build with no of Sony's apps. I restarted it and I got a boot message that my device can't be checked for software corruption, please lock boatloader. After boot up, I checked oem unlocking in developer setting and it wasn't there at all.
What I need to know is :
Is the boatloader unlocked?
Are DRM keys lost?
What firmware I'm on ? Is it the Google's beta pie ( which the owner told me) or is it custom firmware?
Thanks

I flashed latest stock firmware and on boot up it asked for the previous pin/google account. I tried the one I had on the aosp rom but it wasn't right. I tried to contact the seller but he isn't replying. I tried booting up twrp and it did work ( I believe that this means that the boatloader is unlocked). now, I believe that I can no longer use the device unless I flash a custom rom ?
or is there a way to bypass the FRP ?

Unfortunately the previous stock rom user needs to unlock it.
A friend of mine has a Redmi note 9 (merlin), his device recently got into a bootloop, and he can't really use it anymore. He's not a technical person, so he hasn't unlocked the bootloader or messed with it in any sort of way..
My first question is, how did the device get into the bootloop? Is it due to a hardware defect, or did the software just randomly get corrupted?
My second question is, how will i reflash the stock ROM? I know that in order to fix this, I'll need to flash the stock ROM to the device, but the bootloader is locked, so how can I do this? Does Xiaomi have a tool to reflash stock even with a locked bootloader? Or do I need to flash it as an update via an sdcard or something? Does fastboot work on xiaomi devices with a locked bootloader? If so, should I flash the image using fastboot? How would I go about doing that?
I'm quite experienced with Custom ROMs and Recoveries, but I've never had to reflash a stock rom before, so I'm a total newbie to this. If anyone here could help me out, then my friend and I would both greatly appreciate it!

You can flash safely using fastboot, even with locked bootloader.
Official MIUI has signed images, so them will be flashed without issues.
If you can't enter in fastboot, the spflashtool is the only solution.
Good luck.
Ah, its VD171. You know a lot about this device, do you know why it began to bootloop in the first place?
Only who caused that knows.
Alright, apparently I misread his message. He says that the phone is stuck on the Redmi screen, not the MIUI screen. Doesn't this mean that it's stuck on the bootloader, as its not reaching the MIUI screen, so it must not be bootlooping. He says he took it to a repair shop, and they claim that it is a ram/motherboard fault. I doubt that this is likely, could anyone help me with this matter?
I can think of three posibilities:
1. It is stuck on the MIUI screen, but he is calling that the Redmi screen.
2. He HAS messed up his device himself, probably wiped the OS, and now is stuck on a loop at the Redmi screen.
3. It is actually a fault in the phone.
hello, i have a problem with my redmi 9c
my phone just started bootloping alone, i went to sleep and i woke up with my phone dead
the phone is stock, no root, no custom recovery and still with bootloader locked because i don't need features who need it, i can access fastboot but recovery is not posible to reach because Vol+/Power is useless, the phone do nothing pressing those buttons, only with Vol-/Power, so i can't make a factory reset or wipe data, the only thing what i did a couple of hours before the phone broke was change my security pattern (i don't think it's related anyway...), and it was 8 or 10 hours before the issue. sadly the phone warranty expired in january and i have nothing to do at this moment
the phone stops the bootloop after draining the battery, with the bootloader locked of course i'm unable to flash a stock rom, even with MiFlash
what could be the problem?
thanks! (and sorry for my bad english, spanish native here)

Hi, my first guess would be faulty hardware, for example a dead motherboard.
Is there any error when attempting to flash the Stock ROM with MiFlash? Afaik you should be able to flash Stock ROMs even with locked bootloader.

Thanks for the quick reply
MiFlash said "not allowed in locked state" and I guess it's because of locked bootloader, I should try with a specific stock rom?

Hmm okay, yeah that sounds like it's preventing you from flashing simply because your bootloader is locked.
Which Stock ROM did you try? Same as the currently installed version or an older one?

I tried with the last available rom and the previous one, automatic updates were disabled, but I know I updated the phone after buying it
I don't remember if the phone was running last version...
MiFlash should let me flash the phone with the same installed ROM even with bootloader locked?

If you tried an older firmware, it's possible that it didn't flash because of Xiaomi's "Anti-Rollback" Feature which exists to prevent users from Downgrading.
But yes, it should let you flash the same version afaik.
What Region is your Device? On Locked Bootloader you can only flash Firmwares that are from the same Region. (For example Global or EEA)

Alright, have you btw tried flashing directly via fastboot?
Meaning opening terminal and from there flashing all partitions one by one for example "fastboot flash boot boot.img" ?

Oh okay then.
If in the worse case nothing works, your last (paid) solution would probably be to contact one of these "Mi Auth" Guys on Telegram. They have acess to Authorized Accounts that are able to flash your Phone in EDL Mode (might need to open your phone to short test-points though)
I had to pay them about 20€ to get my old Mi 11 (which I sold a while ago) running again after it got stuck in EDL Mode. :/
