Back to Miui official ROM

Hi.
I'm right now on TS CM 13.1 and I want to try the RR. But I didn't unlock the bootloader officially, so I need to do it properly now so I won't end with an locked bootloader.
While I'm waiting for the approval... can I just flash the latest China dev ROM with my current recovery? Or should I flash it from fastboot?
Thank you.

Since you have a custom recovery, try Xiaomi.eu or miGlobe, though be careful as I think latest versions (Android 7) will lock the bootloader. To be safe, I'd flash an older version with Android 5.1 for now.

You can't try RR 5.8.1 based on Android 7.1 as it requires lollipop bootloader.
Or you can flash 6.12.22 and then update to any Nougat Miui Rom available on Xiaomi.eu. This is done via Updater app.

I didn't realise there was a previous RR version with lollipop bootloader.
I already got the SMS with the approval from Xiaomi. I though it would take long. So, if get that right, I should first flash an older Android 5.1.1 Dev ROM and than update it with the Updater app to the latest version with 7.1 . This will lock the bootloader and than I can unlock it officially.
If I do it from from fastboot I can flash directly the latest 7.1 dev ROM, right?
Thank you guys. I always messed around with ROM's with my old GNex, but this Miui stuff confuses me a bit.

No need. Just go in TWRP and see the RR N thread there is a link to nougat blobs. Install that and then install newer TWRP that works with nougat (see android development). I think at this point you'd have to unlock bootloader. Then install room normally

But, as I read in the RR N thread, after I flash those blobs I'll end up with a locked bootloader if I previously unlocked it unofficially. As I did.
And, at least I think, I can only unlock it again from an official ROM. That's why I want to flash Miui.

Whether you have unlocked your device officially or not, it will still lock your bootloader. The key here is if you have the permission to unlock it. If not, then don't proceed. You can officially unlock your bootloader after 5 business days upon receiving the SMS.

Ok. I do have the permission. And can I unlock the bootloader right away with mi flash unlock on a custom ROM or do I need the official miui ROM?

Worked for me with no OS, so I assume you do not need miui.

After you flash the blobs, the bootloader will be locked. Unlock it via Mi Flash. Then flash a Nougat compatible TWRP and you're good to go in flashing Nougat RR.

Locking Bootloader after OFFICIAL UNLOCK [ZE552KL]

This is not a method to relock Bootloader
I see many threads opened on the same topic and closed!
I hope those threads fixed things for you guys.
My situation is Different!
This is not a duplicate Thread.
I just unlocked bootloader on my Zenfone 3 [ZE552KL 4GB 5.5' Model]
After flashing TWRP and using ROMs based on 9.0, I found that we cannot use
UPI [Payment Interface in India (GooglePay)] in the device!
I tried many methods to flash the stock ROM and lock the Boot loader again, But I cant lock it anyway!
I found a thread by @Saktis_Impreza on this topic but I get:
adb>fastboot oem lock
...
FAILED (remote: unknown command)
finished. total time: 0.014s
I would like to share an idea which helped me Regain Warranty after rooting
and flashing over several times on the device ZUK Z2 Plus.
I'm not sure if this applies to ASUS devices.
In Z2Plus we can make the device tampered flag to false by flashing an
older Chinese Firmware on the phone using QPST Flash Tool.
Afterwards we can flash the latest firmware to get back to stock with locked Bootloader.
I know I wont get OTA since I unlocked using the OFFICIAL Method.
I just need to Relock the Bootloader.
I Hope someone would Help.
Thank You

Hello anyone pls help

Actually you can relock bootloader by reflashing factory raw, typing in cmd "fastboot oem unlock" and then, with bl locked, reflashing the latest oreo raw.
My tool does it automatically.

I have already answered this question in this thread. Read it carefully and be sure to use the Turkish MIUI variant. Basically your original MIUI version and variant to avoid a possible hard-brick.

Probably not. I don't know anyone who tried that and succeeded. The thing is, in an unlocked state, the Bootloader (HLOS to be exact) will ignore all errors that are related to custom firmware. Once locked again, you run the risk of a fatal error and will be transferred to EDL mode, which you can't get out from without a Xiaomi verified account (essentially hardbricking your device).
Tell you what, try doing this the opposite way. Lock the bootloader with the turkish 12.0.5.0 fastboot MIUI first, then try to flash the global version 12.0.7.0 through fastboot or recovery and see what happens. That way you don't risk a hardbrick (avoiding repair shop costs), you can always unlock again anyways.

As i've replied before i personally don't know and have not known a case where it succeeded. Why are you afraid of trying? Most will not help you with something if you don't try it yourself first, try it with your bootloader locked as is and if it doesn't work forget about unlocking and locking again.

I don't know if this will work or not. Try going to updater app and pressing download latest release. Then stop it and open internal storage. There should be a folder called downloaded_rom or something similar. Try placing the global rom recovery version there, delete the one that is there and see what happens. Maybe you can toggle update now or flash through MIUI recovery.
If does not work, then i can't help you further. Maybe others who have tried it can.

You can unlock the bootloader only on A11, on A12 it is impossible. You need to go to A11, unlock bl and then go to A12.

You can install the OTA update from here. Just follow the instructions Google provided at the top of the page and you should be all updated. It's only the full images that require the bootloader to be unlocked.

Just go look up factory images for Pixel phones. You can install firmware right from the web browser. You don't need to have root. Root is optional.

Do you mean without an unlocked bootloader? Root is not the same thing and does not determine how you can flash firmware.
If your bootloader is unlocked, you can use the Android Flash Tool. If your bootloader is not unlocked, downgrading is impossible.

This only works if OEM Unlocking is enabled in Developer Options.

@Albi Lukaj, Please be aware that unlocking your bootloader WILL WIPE YOUR DEVICE AND RETURN IT TO STOCK!!!
If that is not preferable, you might try applying the OTA like stated in Post #2, but I am not sure if it works downgrading a version (it probably doesn't)...
