Hello XDA Kenzo community! I unlocked my device's bootloader unofficially by flashing modified emmc_appsboot.mbn from MIUI Lollipop. I will try to flash TheStrix's firmware, which has the untouched MM bootloader over my current ROM which is RR Marshmallow. My question is, can I unlock the untouched bootloader via MiUnlock even if my phone's ROM is non-MIUI or should the ROM be MIUI8? Thanks in advance.

You will be able to unlock using miunlock provided you have official premission to unlock(i.e. if you have unlocked BL using miunlock previously).

I don't think it will work. Because it checks ur MIUI version so far as I know and u need to be logged in to ur MIUI account on phone.

It doesn't check for the MIUI version I guess. Cuz I unlocked the BL when it was running CM 14.

Ok, after it relocked again it's possible with non MIUI ROM.
But u will need to unlock officially first.
And if u unlock unofficial u won't have luck, to unlock officially with non MIUI rom.
What makes the bootloader lock itself when flashing firmware on unofficially unlocked bootloader?
I have found some firmware which remove emmc_appsboot.mbn, but according to other users you need to update that too.
So what I want to know is what happens when I flash a firmware with emmc_appsboot.mbn removed. Will it be the same as when officially unlocked phones flash a firmware with emmc_appsboot.mbn?
Is there any downside to removing emmc_appsboot.mbn?

emmc_appsboot.mbn is the bootloader. If you did not remove that, it will flash a Marshmallow bootloader. The problem is it will relock your bootloader if you're on Lollipop bootloader. Doing the unofficial unlock method means you're on Lollipop bootloader.
Relocking your bootloader while not on MIUI could be a problem so don't flash any firmware with emmc_appsboot.mbn if you've unlocked unofficially. Right now no one knows a method to update to MM bootloader without unlocking officially.
Latest Lineage OS(and those based of of it) needs Marshmallow bootloader to work(otherwise bootloop).
Try official unlock Just wait for one week after applying. Because you will always need the latest firmware to work smoothly on any custom rom . Using patch emmc_appsboot.mbn will keep you stuck at the old miui rom only

I did try Official unlock alot of Times, but it never worked for me so I unlocked unofficially instead. Is there any rom you need to be on? Live dev miui or something?

I have unlocked successfully within a week . I was on latest china dev rom . after getting permission I was facing 50% stuck I waited for 1 week and then tried and was successful. just keep in mind to turn on find device on mi cloud.

You can't check what bootloader you have but if you did the unofficial unlock then you're definitely on LP bootloader.
Firmware is whatever the last MIUI ROM or standalone Firmware you've flashed.
You needed to be on latest MIUI dev to unlock officially.
If you're on Kate though, then doing this doesn't seem to cause problems when flashing the latest LOS. Can't guarantee the same for kenzo though.

Outdated bootloader, hmm. Yes, I think it's the problem as someon else also suggested to first upgrade to latest global stable ROM and then unlock. But how to do that? I googled it, but can't find any method. There's negative comments on every one of the threads. Help me out in this ?

I apologise I didn't tell my problem correctly. I know how to flash stock ROM from mi flash, but what I don't know is how to unlock bootloader from latest ROM. ?
Is there any way apart from official method?

Already tried that. Got permission in 3 hours. But miunlock gets error at 99 %. " Account not bound to this device, go to dev options -> mi status -> add account". Did that too, but gives 8612 and something in Chinese error.

Thanks. What I want to do is either update to latest RR ROM, or to revert back to miui because 25-04 Resurrection build is a lil bit buggy. And the problem while updating to latest build is it gets stuck on "get Resurrected" animation. Same goes for NitrogenOS. Currently, I'm on 25-04 RR build, and it's working okay-ish with some bugs. Now, on asking this stuck animation here on another thread, someone said to upgrade bootloader by unlocking in miui 8. But there's no unofficial way...
On which ROM did you unlock officially? Global stable or global dev or China ROM. Also provide the miui version. I will try to flash that ROM and re-unlock

One more thing, I downloaded miui 8.5.3 global stable recovery zip. It is not having any "aboot" file. Boot.img is present. If they are same, I'll have to delete boot.img, right?

Hello im on nougat RR. Also officially unlocked. How can i revert back to miui DEV MM ?
Hi,
I have 2 RN3P, both running a custom rom.
One has an unlocked bootloader and another has a locked bootloader.
I'm looking to sell these phones.
I would like to know how can I return to a COMPLETELY stock rom, meaning NO TWRP, locked BL, etc.
I'd prefer not triggering ARB.
Could anyone please tell me which firmware to flash and which method to us ? TWRP or MiFlash ?
I'm ok with using an older firmware too, I just need to return the phone to factory condition.
Thanks for any help.

Download and Flash this fastboot stable rom for kenzo .
For unlocked bootloader u can flash using mi flash and fastboot mode.
For locked bootloader u need to put phone in EDL mode and flash using miflash.

ARB is Anti Rollback Protection bro
this will disable u to dongrade to lower ROM version bro
okay bro?
ARB is not implemented for RN3. So don't worry, just flash latest fastboot ROM from official website (http://en.miui.com/a-234.html) using Mi Flash (clean and lock) and you will be good to go.
I have done it a few times, haven't faced any problem even for a single time

you can try this method :https://en.miui.com/a-234.html
Download global Stable rom( I flashed DEV last month and it worked for me) if you are form India. If miui flash tool doesnt detect your phone in EDL mode, use miflashtool 20160830 / https://androidmtk.com/download-xiaomi-mi-flash-tool
Please use caution and do it at your own risk . I reverted my phone to DEV fastboot ROM & locked bootloader to getaway from ZCX TWRP issues.
My issue is resolved.
I used the oldest rom I could find (marshmallow).
I used MiFlash, fasboot for unlocked bootloader and EDL mode for locked bootloader.
Thanks for the help everyone!
hello guys, I have installed nitrogen 8.1 with twrp of team recovery project. Two years ago I officially unlocked the bootlader, but it seems that when I updated firmware the bootloader was blocked again. What is the easiest way to unblock it again? Is there a risk with the bootloader blocked from installing another rom via twrp?
