hello,
first of all i recommend the advanced users to try this method first to see if they succeeds or not if they then, cheers for the new unofficial bootloader unlocking method. here i will provide steps to do:-

Things you need:
- fastboot rom MiUi 8 8.2 will work
-the modified bootloader file
-helpful quick answers :)


ok so here we begin

PREREQUISITE
-adb and fastboot setup already on your pc
-usb debugging and oem unlocking must be enabled(from developer options)
-mi flash tool ~>Get older version from here (use 20160401)
-driver signature off


step 1
Enable USB debugging and connect device to pc,
now open fastboot and adb folder and there open cmd and type
Code:
adb devices

step 2
you can recognize the device connected to pc

now reboot device to edl mode
Code:
boot to edl by button combination or fastboot command

you can see your phone is in edl(emergancy download mode)

step 3
extract the fastboot file, and goto extracted_folder/images
there you can find a file named emmc_appsboot.mbn

replace with the downloaded emmc file(from begining of post)

step 4
open mi flash tool and connect phone via usb and click on refresh you can seee a COM port with a number on display,
now browse and load the fastboot rom.

step 5
(in this step i'll be specific as same as redmi note 3 bootloader unlocking method is)
click on advanced and there
and choose these

Browse to flash_all.bat in Fastboot rom folder at First option ,
Third option to prog_emmc_firehose_8976_ddr.mbn ,
then last two options browse to rawprogram0.xml and patch0.xml


step 6

after selecting files in advanced ,go back and click on refresh

step 7
now flash the fastboot file as soon flashing completes remove cable and keep holding fastoot combination keys
now you are booted into fastboot :p

step 8
the fun part(i guess)
goto adb and fastboot folder and open cmd there'

and type
Code:
fastboot devices
to check if device detected or not

now type
Code:
fastboot oem unlock-go

now it should show

Code:
...
OKAY FINISHED
like this

step 9
now if you succeeded step 8 completely
i'd suggest you to check if bootloader is unlocked or not

type
Code:
fastboot oem device-info

if that shows as
Code:
<bootloader>    Device Unlocked:true

then Congratulations.. you successfully unlocked bootloader without permission from xiaomi :p


now for the people who are trying do please inform if this method worked or not
(will be helpful to me for re edit post with ease steps)
credits to my whatsapp friend who given me required files lol :highfive:




AGAIN please do reply, if this method works or not :) if worked then cheers :victory:

This is the second time I see this Note 3 unlocking stuff posted here...
Since when adb reboot edl works for MI Max? I'll tell you... since never...
Have you tried this procedure yourself? I bet you haven't...
So don't post something so risky without confirming it working personally, please...

I will strongly advice everyone even considering this!!!

Mi Max has Edl Mode but it cannot be booted by adb reboot edl, edl in mi max can only be booted by combination of buttons.

The method is much too dangerous to test, the modified bootloader file depends on android version and may brick your phone - read more in RN3 thread.
You should not have even posted such a method without personally testing it - we, as in users, are not guinea pigs.

step 5
(in this step i'll be specific as same as redmi note 3 bootloader unlocking method is)
click on advanced and there
and choose these

Browse to flash_all.bat in Fastboot rom folder at First option ,
Third option to prog_emmc_firehose_8976_ddr.mbn ,
then last two options browse to rawprogram0.xml and patch0.xml

Xiaomi MiFlash has no "Advanced" button, you are not even linking to the program you are advising to use.
Please remove this post and either do the procedure yourself first or do not post such pos here as nobody could even complete the procedure.

Actually Mi flash tool has the option for advanced .. if you had the older version .. till now i havent updated to latest version yet, also if you may read above post i told that i currently dont have my max now, and i aint gonna get it in next 1 or 2 years, my brother took it and now he is at his hostel...

I ll link the old miflash tool, and the dangereous thing is only one soft brick(stuck at logo) and bootloop, I have experienced some that bootloaders doesnt vary device by device...
So probability is to get a stuck on logo or get a bootloop its simple that you just load the original fastboot firmware and flash, that reverts back to normal state, for now,
I'm just trying to help, if people dont like it then I will defineatly leave.

Yes! We appreciate you trying to help but your missing the point... You have uploaded a guide from another handset expecting it to work for our devices having not tested it previously, the guide isn't even for out device so have fun being guinea pigs

I didnt took all things from rn3 bl unlocking page, i just took method of flashing. And the bootloader file thats taken from officially unlocked bootloade, and i just told if previous post i dont hav max right now, so i wish if someone tried this and if he succeeds.. then its very good news for all locked bl users..
But i think none is not even trying :(

Definititely some procedures must be changed and adapted to mi max. Experimented developers has portion of truth but some users can`t get answer to unlock devices and me personally if my bootloader was locked don`t want have a device wich can`t be real owner.
Opennig file emmc... remember that an old trick from kitkat to unlock with sucess my old xperia z. some looks be based on the principle to replace original values in the clusters just for zeros. I uploaded two orginal and unlocker emmc files to consider this but of course I can`t confirm cause my bootloader is unlocked.

Some ideas aloud.
There are differences between locked and the official unlocked bootloader (please, see in the hex-editor the end of both files). It's a right idea for replace the locked bootloader (emmc_aboot) to official unlocked emmc_appsboot. The official unlocked emmc_appsboot we can get by dump of the partition in official unlocked device and this binary file will be have the .img extension (uncompressed binary file).
For checking we should check two binary files in the hex-editor: emmc_appsboot.mbn from ROM for fastboot flash and modified bootloader file from author. But files with .mbn extension should be uncompressed.
Sorry, but I don't know as uncompress the .mbn file.

Yeah i checked in hex, i guess its the some kinda lock codes with it so they got removed(i m noob in hex ':) )
As far as .. result will be known by practically

Maybe developers can make something similar to safestrap, it was a great project based on bootstrap (now abandoned) that works with a modified recovery that allows install almost any rom on bootloader unlocked (and unlockable cause company never want to unlock it at least till the time I used) on my old galaxy note 3 at&t. This app created a second slot and more directly to install roms.
