If the edits given in guide is not working for you, then remove these lines to and try. I have used the given updater script myself. Worked fine.

Yes. Delete recovery update(recovery from boot in system dir) , aboot.mbn (locked bootloader) and edit updater script in Ota zip before flashing.

You have to install add and Factbook drivers.

Hi, I'm currently on 7.2.3.0.

I wanted to know if i need to flash 7.1.8 and then unlock or can I do it directly from this version.

Thank you

..i'm guessin this is just for the 'Pro' aka Snapdragon variant, and NOT for the MTK variant?

and for MTK there's just the official way to unlock bootloader?

[Xiaomi Redmi Note 3 Guides, News, & Discussion] Rizezky:
Hi, Do you know how to relock my bootloader? I unlocked it with your method. Here's my current condition : on 7.2.3.0, twrp installed, rooted. Do i need to flash back to stock unlocked 7.1.8.0 in order to remove twrp and root, and then flash(fastboot) the stock 7.1.8.0 emmc_appsboot.mbn? I need to flash to Chinese dev/global to unlock it officially. Thanks for your reply
[Xiaomi Redmi Note 3 Guides, News, & Discussion] agusyud:
never succed with this ota..

but i realized..

the important point here just to get TWRP in my device..

so after i got TWRP , download the full recovery 7.2.3 rom

modified boot.img, exchange the .mbn and flash it through TWRP

and i got unlocked 7.2.3

then go root session

just flash super.su and flash modified boot.img 7.2.3

everything fine now with 7.2.3 unlock, twrp, and root
[Xiaomi Redmi Note 3 Guides, News, & Discussion] sunu792002:
So, you have succeed with that steps? can you upload the modified boot.img and emmc_appsboot.mbn to replace inside recovery rom file? or just using the file in page 1?
[Xiaomi Redmi Note 3 Guides, News, & Discussion] the_rebel:
Quick question: In the MiFlash Tool Advanced tab, what file is to be selected for Flash Programmer?

Edit: never mind - Winrar screwed up and I didn't get the file I was supposed to select there. Used Peazip and it's alright now.

somehow u lose ur twrp

boot to system, enable usb debugging, connect device to pc and always allow usb debuging

reflash twrp..

and u can make a backup from twrp for 7.2.3
[Xiaomi Redmi Note 3 Guides, News, & Discussion] the_rebel:
I have tried these set of instructions about 5 times now, and it hasn't unlocked bootloader for me. It ALWAYS results into:

E:\Android\ADB>fastboot oem device-info
...
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Charger screen enabled: true
(bootloader) Display panel:
OKAY [ 0.024s]
finished. total time: 0.026s

E:\Android\ADB>fastboot oem unlock-go
...
FAILED (remote: oem unlock is not allowed)
finished. total time: 0.018s

And then the device is soft-bricked. Always.

Any ideas what could be going wrong?

(RN3 32GB SD running 7.2.3)
[Xiaomi Redmi Note 3 Guides, News, & Discussion] supermeerkat:
I had the same issue. Solved it by enabling "Enable OEM Unlock" in the Developer menu (same menu where you enable USB debugging).

To unbrick the device, start it in fastboot mode and connect it to the computer. Then use fastboot commands to flash the stock (unmodified) emmc_appsboot.mbn file.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] the_rebel:
Thank you! So is this the right command to do it?

fastboot flash [B]boot[/B] emmc_appsboot.mbn

and the mbn file is original/stock obviously as you said.

Please

confirm if the flash command is exactly right, I wouldn't want to hard brick my 1 day old phone! :)

Then I'm guessing the phone would boot into the OS and I make that dev settings change like you instructed?
[Xiaomi Redmi Note 3 Guides, News, & Discussion] supermeerkat:
The fastboot commands should be:

Fastboot Flash aboot emmc_appsboot.mbn

Fastboot Flash abootbak emmc_appsboot.mbn

Fastboot Reboot

I can't take credit for these since I found them on another thread (which I can't remember the link to). Make sure the emmc_appsboot.mbn is in the same folder as the fastboot.exe file. The phone should boot after this and yes, enable OEM unlock and try again.

Another mistake I made later on was when flashing the OTA update in TWRP, I accidentally selected the option to mount /system as read-only. It still did the OTA update, except I had a fairly broken ROM with no launcher! Was easily fixed by using TWRP to flash the ROM again (Edit - some changes had to be made to the .zip file before flashing to avoid bricking, see http://xdaforums.com/redmi-note-3/how-to/guide-to-flashing-miui-based-roms-twrp-t3359927).

Now on to adding recovery, rooting, and updating back to 7.2.3 :fingers-crossed:
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Sudeep Duhoon:
I believe you can directly flash the dev rom from mi flash tool and you will get locked bootloader too.

Try the updater script provided in thread.

As there is 7.2.3 miui fastboot images available now you can flash that to avoid ota applying step. I will get my 32gb note 3 on monday i will update guide then. I don't have any phone right now.

Yes. For kenzo.

You can always flash locked mbn to relock bootloader. Guide will be edited and commands will be added. Thanx for mention.

Will try to look for that but i doubt i will find it.

Guide will be updated. Thanx for pointing that out.

Can you help me doing this for Mi5 too ? I have 2 of them one is unlocked and rooted with twrp, other is still locked.

Thank you for your amazing brain..
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Sudeep Duhoon:
Thanx for the appreciation. :)

You can unlock the other one the same way you unlocked first? May be? Or are you asking to make a topic?

After deleting emmc file, place unlocked emmc in it's place too. (in the zip) then flash.

Also mount system read/write in twrp. (in Mount option)

Have you not edited the required files in the Ota zip?

I got my 32gb model yesterday and all this worked perfectly in that too.

Sorry for your loss.

[Xiaomi Redmi Note 3 Guides, News, & Discussion] Sudeep Duhoon:
No.

Thanx for the screenshot. Have you flashed the patched boot.img before flashing the Ota?

The Ota will only patch 7.1.8 boot.img which must get flashed when you flashed 7.1.8 rom using mi flash tool.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] harshk60:
Now i just download 7.2.3tgz and flash as same as 7.1.8 by replacing emcc.. But after rooting and xposed also miui sucks,as u cant disable miui launcher (for using nova launcher ) and security app other wise many functions, setting menu has been changed. And ram management is very poor. So after that i again flash aosp rom. Now i will stick to it until there some other new stable rom will not come.

[Xiaomi Redmi Note 3 Guides, News, & Discussion] harshk60:
Only one, this same happen to me but then i downloaded 7.2.3 full rom.tgz and flash again like 7.1.8. ITS flashed successfully. But like says above miui sucks so i go back to aosp rom.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Sudeep Duhoon:
Disable miui optimization in developer settings to get these disabled options.

First unlock the bootloader using this guide. (or official way)

Then flash the eu rom.

I think multi eu Roms do not locks bootloader. Still to be on safer side, replace there emmc with unlocked emmc before flashing and you are good to go.

I don't own a mi5 buddy, still WI tey to look into it.

Why you flashed globalboot.img of 7.1.8?

It was not in the guide.

update:

Okay so , i edited the updater script and replaced the emc boot thing in the ota of 7.2.3 to 7.2.5. i flashed the ota , got an error patching the boot.img so i rebooted and got stuck on bootloop to twrp, i tried restoring the boot img backup but no use.

In the end i re flashed 7.2.3 using flash tool

If anyone has updated successfully from 7.2.3 to 7.2.5 please help! and explain the procedure
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Sudeep Duhoon:
Will update tomorrow (i dont have my replacement phone till wed)

That's because your 7.2.3 boot.img is patched one. You have to flash 7.2.5 ota on stock 7.2.3 boot.img.

If you have rooted do this

1 flash fastboot 7.2.3 rom

2 follow guide till twrp flashing by fastboot

3 flash edited 7.2.5 ota

4 flash patched 7.2.5 boot.img and supersu.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] bipindr123:
yeah i kinda realized later that day , thanks man, i did the same with creating a backup(data and system for future use) using twrp but even though ota flashing and patching went without error, i would either bootloop back to twrp or boot without updating to 7.2.3

So i tried WITHOUT creating a backup in twrp and just flashed 7.2.3 fastboot then the ota then patch and it worked! yay

so i guess creating a backup using twrp somehow ****sup and creates some problem or maybe it was because i was using the safe twrp by cofface :/

But the driver still hasn't changed from ADB Interface to Android Composite ADB Interface

And under the ADB command console it is not the same as yours:
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Sudeep Duhoon:
Install the drivers. See troubleshooting part. Report if still not working.

I got my replacement today and i found out the problem with ota flashing. Right now my pc is off so i will update the guide tomorrow. Now it is working everytime.

Use official twrp and stock 7.2.3 boot.img

The fix is to mount system as read only on first recovery boot. Will update guide tomorrow.

Is it possible for me to downgrade to do the unoffical unlock? If so, do I just follow these instructions? http://en.miui.com/a-234.html
[Xiaomi Redmi Note 3 Guides, News, & Discussion] clandestino123:
hi guys, I'm on 7.2.5 global stable. I want to unlock the bootloader.

1) do I need to use the 7.1.8 fastboot Rom? Or can I follow the same process, but using the 7.2.5 rom that I've already downloaded?

2) In MiFlash, I select "advanced.." and browse to the relevant files as per the instructions. Then I hit "enter" or "x". Problem is - If I hit "advanced" again (just to check that I selected correct files), it appears my selections have not been saved? they reverted back to the originals... did I do something wrong?

I am still experiencing the same problem with both my desktop and laptop showing as "ADB Interface" in the Device Manager after all the driver insttallation.

I am at MIUI Global 7/2 | Stable 7.2.5.0 (LHOMIDA).

I just got this phone in Wednesdayin Hong Kong and accidentally update the rom.

Do I need to downgrade the rom from the latest, if so, how do I do so? I have read through the forum where there are so many variant and not sure which is the most suitable one.

Finally solved- by installing the Mi Setup app (MiSetup3.2.1.3111_2717.exe) and uninstalling.

Thanks for the tutorial.. It worked fine for me. Now I'm on 7.2.5 w/t root and twrp.

I have 2 questions

2) the 7.3.2.0 ota is available. When will u update the modified emmc and boot.img ?

[Xiaomi Redmi Note 3 Guides, News, & Discussion] Sudeep Duhoon:
Yes. You can use 7.2.5 fastboot rom, rest of the procedure is same.

The backup you restored was 'made' with twrp set as ready only or read/write?

How to make is already available in guide.

Rar the stock 7.3.2 boot.img and send me. I will send patched.img.

My new redmi note 3 will be delivered tomorrow (old one bricked when trying to officially unlock)

Yes.

Rooting can't affect ram usage as far as I know.

Send me stock boot.img (Rar it) I will patch and upload.

Yes. Is you have already made unrooted system and stock boot.img backup with twrp set as read only. Set twrp read/write, restore that backup, set twrp read only, apply Ota, make new backup, set twrp tead/write, flash su and patched boot.img.

Flash the fastboot rom using mi flash tool.

[Xiaomi Redmi Note 3 Guides, News, & Discussion] Sudeep Duhoon:
Chances are, you will get stuck at 50% when you will try to unlock it officially. It happened in my case. Tried global stable, China stable, China dev Roms.

Wait for few days, then flash China stable fastboot rom. And China developer recovery rom (using updater app) and try to unlock it officially.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] bipindr123:
news is that there is no problems unlocking it on the global stable 7.3.2 , many members were able to do it!

my question is that unlocking it unofficially and then getting official permission is the same as official unlocking or does the mi unlock tool do more than just unlock
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Sudeep Duhoon:
It's not same. You can flash any rom in recovery without patching for emmc aboot (unlocked bootloader) if you have unlocked officially.

If your are sure enough then get to 7.3.2 and try to unlock. Please revert back if you get success. :)
