I am not responsible for anything done wrong for you and your device. Sorry!!

You have two options to follow, the 1st one is long, may be difficult to follow. I recommend you to read option 1 and 2 both but to follow option 2

OPTION 1

Hello friend this is a short tutorial for those who have just bought the Beast Red Mi Note 3.

This guide is only for Redmi Note 3(Qualcomm Snapdragon 650 2GB/3GB version) users.

The Device's codename is kenzo. It also called Xiaomi Redmi Note 3 Pro. On MIUI sites Its also mentioned as HMNote3Pro so don't get confused.

The below mentioned MiFlash-Tool is required in emergency. Installing Mi-FlashTool in PC also install all the Quallcomm and Xiaomi Drivers to make your device function with PC at any mode( recovery, fastboot or system mode) Make sure before installing MiFlash-beta setup, You have disabled Driver Signature Enforcement in your Windows PC. To know how to disable check on Microsoft sites for your particular OS.

Requirements

1. A PC with windows 7,8,8.1 or 10 32-bit or 64-bit with .NET Framework version 3.5 installed. Before you install Mi Flash. To download .NET framwork visit the microsoft website.

2.Download Xiaomi MiFlash-Beta(This beta version works good and also support 32-bit Windows OS) http://en.miui.com/forum.php?mod=at...2NGJkfDE0ODE4MTQxMTh8MTU5MjAzMDUwMXwyODE5Nzk=

3.TWRP Recoveries- download all these 3 recoveries

a. Alka TWRP http://en.miui.com/forum.php?mod=at...xMmZifDE0ODE4MTY5NzZ8MTU5MjAzMDUwMXwyODI3NzM= (for emergency backup and restore) (this recovery is most necessary to backup all the partition of our device. RN3 comes with all about 40 partitions, and their are many important files stored their. So at anytime you get any problem just restore. The recovery image file is compressed in a .zip file. Therefore, you may need to firstly extract it using Winzip on your PC or extract it using ES File Explorer on your phone. One more thing, this build is for Redmi Note 3 Qualcomm Snapdragon (Kenzo).

b. Cofface TWRP https://drive.google.com/open?id=0B5bSNUUrjm6JQjFhUEkzZXZ2bkk (zip password www.cofface.com)

c. Official TWRP https://dl.twrp.me/kenzo

If you want to flash custom Rom like Cyanogenmod, xiaomi.eu, Resurrection Remix etc. This tutorial will help you to use all those thing which can be done on our Beast :).

:angel: first of all you guys get the Bootloader unlocking permission from en.miui.com/unlock/ (recommended) and always sign in the Mi Account with valid mobile number and e-mail which is used by you currently and can be accessed by you anytime. Goto setting in the phone and register for Mi account and login. Enable Find Device feature.

i have not checked ZC-X TWRP RECOVERY because i have seen some people getting problem from zcx, but now it is upgraded. So it can be universal for everything( like flashing any official/stock/custom rom(as cofface and official do), maybe it supports all partition backup( like alka do) and also it can be used to update or upgrade you MIUI based rom. Check it at your own risk.

3.USB DATA cable (the one that came with your device).

4. device battery charged at least 50%.

5. A good observer and patient most of patient.

I don't think about any other way to unlock bootloader. You can find them on other places but I don't find them easy than this.

So I am supposing that you guys using your phone with stock MIUI Rom that should be MIUI 7 or MIUI 8 :) with stock recovery and You got the permisssion official to unlock your beast :).

So just unlock the bootloader by using MiUnlock tool from PC. Store all these tools in your PC for future process.

Now you have unlocked bootloader to check the status just boot your phone into fastboot mode by pressing volume down+power key when your device is off then use this fastboot command fastboot oem device-info to check the bootloader info if it says bootloader unlocked:true then you are ready to go. If you don't know how to setup adb-fastboot environment and driver check it here http://xdaforums.com/showthread.php?t=2588979

Put unlocked bootloader phone in fastboot mode,connect device to PC using USB cable and check the bootloader status again to verify it is unlocked or not by using command fastboot oem device-info. Now copy(don't cut because you should have a backup plan for each process) all the recoveries ALKA TWRP, CoffaceTWRP and official TWRP recovery to the adb fastboot folder and rename alka twrp to alka.img,cofface twrp to cofface.img and official twrp to official.img. Please copy and rename one by one for don't getting confused. If you accidently rename cofface to alka then it will be not good to you after flashing. So take each step carefully.

(if you have managed environment variables on PC then you can use adb fastboot commands any where in PC, That is a good idea. So if you want to know how to set environment variables just comment here I will give you all the steps.)

Now just press continuously the Shift key and press RIGHT CLICK on the blank area of window.

An option menu will be showed click on open command prompt here.

A black backgrounded command shell will be opened.

Now type fastboot oem device-info and press enter key.

If it shows bootloader unlocked :true then proceed to the step 1 and if shows false then don't proceed unlock your bootloader which is shown above with this symbol :angel:.

Step 1:

A.First of all take backup of internal sd by copying all the folder and files in your PC's folder and name this folder to KenzoInternal :) you can use any name. And delete more files in internal to get atleast 5GB space.

B.You shuould have atleast 5GB space in your internel to back up your all device partition through ALKA TWRP.

C. copy all three recoverys(cofface.img,official.img and alka.img) in your phone's Internal SD directly or make a folder recovery and place there.

Now go,read and follow the instruction from below

Boot your phone in fastboot mode and connect with PC

open command prompt in adb-fastboot folder where you have copied all the recovery images(official.img,cofface.img and alka.img)

Type on command prompt:

fastboot flash recovery alka.img

it will be flased in atleast 10 seconds.

Now we have to go directly to recovery mode from fastboot mode not in system so care fully press volume up + power key at the same time in your REDMI NOTE 3 and when your device vibrate leave the power key but don't leave the

volume up

key until the recovery window get shown. If your device get booted to system not in recovery then maybe your flashed 'alka' will be replaced with stock recovery, and may be it get bootloop :) or maybe it will boot successfully but have some problems like Wi-Fi radio get disabled.

Read the above step again and do everything carefully.

Step 2:

[[ If on welcome screen the language shows in chinese or other, then simply swipe on first screen and touch on the 2nd column and 3rd row in menu and then touch on the icon(shows like earth or sphere) and choose English and then done. ]]

In recovery go to BACKUP and mark all the partition I said all the partitions (you can leave unmarked the DATA partition if you are not wanting to make backup of your own installed applications and their data. It will decrease the backup size and also the TIME) their may be 35+ partitions. And swipe to backup. Their are some partitions like system,efs(stores modem and radio and may be your IMEI information) etc have the sensitive data. So you are mostly recommended to mark all the partition except DATA(optional).

GREAT!!! wait until getting backup.

Step 3:

Now touch on Install menu in recovery and touch on Install Image that is always in the right below of the screen upto the swipe handle.

Now browse to the root of internal sd or the folder where you have copied all the recovery images(cofface.img,alka.img and official.img). And choose the cofface.img and swipe to install.

Now get back by touching on back arrow symbol on left bottom.

Step 4:

Touch on REBOOT menu in recovery and then touch on Reboot to recovery or to recovery.

Your RN3 will reboot again to recovery(which is now cofface).

[[ If on welcome the language shows in chinese or other then simply swipe on first screen and touch on the 2nd column and 3rd row in menu and then touch on the icon(shows like earth or sphere) and choose english and then done. ]]

Now touch on reboot and thenreboot to system.

If it shows that your recovery will be

If any query shows saying your phone is not rooted just touch on Do not Install

your phone will boot to MIUI system as it was. and it has a custom recovery(currently cofface).

if you want to root your device then download superSu.zip from https://download.chainfire.eu/921/SuperSU/UPDATE-SuperSU-v2.65-20151226141550.zip and place it in your internal sd card of phone and then boot to recovery by pressing power key+volume up key on same time then go to install and choose to install for supersu_vx.xx.zip file and swipe to flash. Then get back and wipe cache and dalvik/ART cache or some times it also reboots automatically.

Kindly follow the on-screen instruction which shows on screen during installation.

NOTE: It may be bootloop or take too much time on first boot after installing superSu.

SuperSU app and all the applets(including busybox tools) also comes with superSU zip file. So no need to install it through PlayStore. However you can update from PlayStore.

You are strongly recommended to take the backup(whole partition backup taken by ALKA TWRP) and copy it to Your PC that is the life of your mobile. I know you can flash An official MIUI rom through PC using fastboot or EDL method but If you lost your EFS partition then You will lost your IMEI which is unique to each and every devices. In Qualcomm Snapdragon based phone It is hard to recover IMEI. I say hard not impossible. Their are many forum that give solution to this but It is highly recommended to have this backup copy to your PC. You can find your backup in the /sdcard/TWRP/Backup/ OR open Internal SD then go to TWRP folder then open BACKUP and then a folder like 5exxxye. just copy this folder to your PC and keep it safe or you can save it to other places also that will be more good and also show your smartness. :):):):)

How to install custom ROM or OSs in RN3Snapdragon?? Hmm come here

NOTE: Always flash all custom ROM(Except MIUI) through official TWRP. But when you have made your mood to install custom ROM you have to flash official twrp through either with TWRP(currently cofface in your device) or with fastboot command using same method that I have explained above when we have flashed coffaceTWRP in your device or use this commandfastboot flash recovery official.img

I have tested many ROMs but I found most stable Resuurection Remix(based on Marshmallow) and CyanogenMod 13(based on Marshmallow) yet. Everything is working fine except VoLTE. Their are many available ROms that supports VoLTE based on Nougat(Android 7.0 or 7.1) but have some bugs with camera. (The Cyanogenmod 14.1 officially is also declared but in experimental mode(nightly)(not recommended for you.))

I am going to show you the steps to flash custom ROMs without getting into any problem but you are recommended to follow each steps carefully. Thanks :):):)

Suppose you have downloaded official released Cyanogenmod 13 for your phone from here https://download.cyanogenmod.org/get/jenkins/174586/cm-13.0-20160816-SNAPSHOT-ZNH5YAO0FI-kenzo.zip (It is recommended to download it to your PC for backup plan). Having a copy of this backup in your PC makes you free to delete it from internal SD to free the space when you are in a Stable Rom or in a ROM you loved and want to be always with it.

then place it to your internal SD. now follow these steps... Check out your device battery is 50+ % charged.

Step 1:

Reboot to recovery. Go to install and choose install image. Now choose official.img(officialTWRP) and then swipe to flash/install it.

Step 2:

Now reboot again to recovery by choosing REBOOT in recovery menu and then RECOVERY

your phone will be rebooted to official TWRP recovery which is not supported by MIUI. I mean official recovery doesn't have the ability to patch the boot image., that is why I said it is not supported.

Step 3:

Now go to wipe/format menu in TWRP recovery(I am supposing you have the back up with alka twrp before and have copied it to your PC also.). Choose 'advanced wipe' and Mark these partition System,Data,Cache,Dalvik/ART cache. Do not choose Internal SD, Micro SD or USB OTG. and swipe to wipe.

Step 4:

After wiping now you have not any Operating System installed. Just touch INSTALL in RECOVERY MENU and choose the ROM ZIP file which is cm-13.0-20160816-SNAPSHOT-ZNH5YAO0FI-

kenzo

.zip (for example). Always use the ROM that is build for Your Device. Since above zip file's name shows it is for kenzo that is your RedmiNote3 Quallcomm Snapdragon.(just check the underlined word in zip file.)

and swipe to flash and wait no matter how much time it takes. Just wait don't try to reboot.

if you want to flash google apps(GApps) like play store and play store services you have to install it also after flashing the ROM zip file. to download GoogleApps go to opengapps.org and choose arm64 from architecture menu and choose android version for this ROM(Cyanogenmod 13) choose 6.0. choose which package you want I recommend you to use pico it will only install play store and services and you can also install other google apps through Play Store later.

If you want all google apps then choose 'aroma' it has a built-in file explorer to choose particular app in recovery.

Step 5:

After installing cyanogenmod and GApps wipe cache and Dalvik/ART cache again. Do not wipe anything else.

Now its time to reboot to the system.

first time it will take atleast 2 to 10 mins (depends on the open GApps package type) for optimization of apps.

After that go and enjoy..

Any problem comment below.

To revert back to MIUI again.

just copy the backup folder you have taken before, to the folder /sdcard/TWRP/BACKUP/ and reboot to recovery(currently official).

and choose to install image in recovery menu and then choose alka.img and then reboot to recovery again(using recovery menu).

You will again reboot to recovery (currently ALKA).

In alka recovery menu choose to WIPE and wipe these partition SYSTEM,DATA,CACHE,DALVIK/ART CACHE.

then choose RESTORE from recovery menu and select your backup folder and it will show the list of all the partition you have made backup. Mark all and swipe to restore.

Note:sometimes it shows an error during restore that it can't restore firmware partition. If it show this error kindly choose to restore again and mark all partition except firmware partition then swipe to restore.

After restoring backup(MIUI) do not reboot just. choose to install image and install cofface.img again because this recovery works with MIUI.(Cofface twrp paches boot image automatically which is required to make custom recoveries to work with MIUI ROMs ) after installing cofface.img. Reboot to recovery again and then reboot to system.

Now wait if it takes too much time (may be 15 to 20 mins).

Now you are come back to your MIUI ROM.

MUST READ:

1.Always check your bootloader status after and before flashing any ROMs(boot to fastboot mode connect USB to PC and type the command in command window fastboot oem device-info.

2.If any time it shows bootloader unlocked: false then use Mi Unlock tool to unlock the bootloader again. You have to use same user-name/mobile number/e-mail and password to sign-in the UnlockTool which you have sihned in your phone.

3.No matter how many ROM you have flashed or which OS you currently using. MiUnlock-tools always recognises your phone.

4. During unlocking the phone your PC must have an internet connection from other sources.

5.You can't use your phone's wi-fi hotspot to unlock its bootloader;) because it should be in fastboot mode.

6.Always make back up and store them in safe place.

OPTION 2

Now you can use zcx recovery which is Universal to flash custom/stock/miui ROM without any problem. So unlock your bootloader and flash ZC-X twrp recovery, and follow the instruction comes with it, you don't need to follow the long procedure given above. You should use it with Marshmallow based MIUI ROM too which comes with by default DATA partition encryption. It can automatically decrypt DATA partition. So go for it here https://www.google.co.in/url?sa=t&r...DwoAzQEtfzPxp4Shw&sig2=SOZcDMBpgO_teBIK6lNnhw
