[Xiaomi Redmi 3 Guides, News, & Discussion] YasuHamed:
UPDATE 27 DEC2016

-I received SYSTEM UPDATED NOTIFICATION ON 27 DEC2016 FOR MIUI8 on 5.1.1 (1.2GB), while my device was bootunlocked and ROOTED.

- after updating, twrp + root was gone

- so i flashed twrp IDO and flash supersu + lazyflasher and rebooted my device

---------------------

Recently I did something wild by buying Redmi3. For a die hard Sony Xperia fan over last many years it was something wild for me.

Immediately I felt the boundaries within MIUI8 where

- no app can be disabled

- no application dock / all app icons landing on launcher

- MIUI mediocre music with no equalizers

- bundled google and other duplicate apps (Miui galary + google photos) which and cannot be removed

however the features i enjoyed the most in MIUI8 particularly

- Dual APPs

- detailed dual sim control and renaming status bar icons/shape

- detailed control of memory optimization in developer options

- better memory optimization ( atleast for facebook and messenger which take gb/s of place to run :( )

i started my investigation immediately about rooting the Xiaomi Redmi devices running on MIUI8 (android5x) and the short and sweet version says

1. Unlocking Bootloader

2. flashing TWRP

3. flashing SuperSU

4. Flashing LazyFlasher

BOOTING in to SYSTEM.

however the above missing all the bleeding saga of work around you have to perform in order to reach the point where u actually install twrp.

UNLOCKING REDMI3 (REDMI DEVICES) ​

prerequisite~~~

MAKE BACKUP OF YOUR DEVICE!!!!!!!!!!!!

DO IT ON YOUR OWN RISK

I AM SHARING MY OWN EXPERIENCE HERE!

ONLY ONE DEVICE SHOULD BE LINKED WITH ONE MI ACCOUNT ( what i have read ov

1. once you start using REDMI, you must create MIUI account in your device- verified by your Mobile Sim Career / valid email and having legitimate details about you. the more valid details you give to your MI Account, the chances of unlocking bootloader are more. I even had to connect it with my only facebook account!

2. for REDMI3 download the DEVELOPER ROM from http://en.miui.com/download-298.html and put it in the mobile's SD card or internal memory.

on Redmi3 goto UPDATER APP (in folder TOOLS) and click the 3 dots top/right and click CHOOSE UPDATE PACKAGE and install the DEVELOPER GLOBAL or DEVELOPER CHINESE ROM MIUI8 over stableROM

https://drive.google.com/open?id=0B31ivZaiUAGMa3lPUWVnWnVXdXc

https://drive.google.com/open?id=0B31ivZaiUAGMNXBCLWdnWHpYbXc

it may give you warning like its older version and all data will be wiped. Proceed anyways. the device will BOOT an install DEVELOPER ROM. This process took 1 hour and i had Developer ROM in my REDMI3. after booting i logged in to my MI ACCOUNT. (DATA WIFI enabled)

3. NOW~~~~ goto http://en.miui.com/unlock/ and fill the form , asking your MI account details and VALID reason why you want to unlock your redmi device. Once done you will be asked to wait for SMS by XIAOMI. it may take 10 to 12 days. at this point if anything about you account is fake or you change your SIM CARD/number in you REDMI3 / Redmi. your bootloader request will be denied. I recieved my SMS on day5

https://drive.google.com/open?id=0B31ivZaiUAGMVnMzb3RKSEtTdkU

3. once you get the sms, download MIunlock TOOL from

http://en.miui.com/forum.php?mod=at...kMjVifDE0Nzk5MDA2OTJ8NTQyOTQ4MzM5fDQxODQyOQ==

4. now here is the Tricky part! which i found after so many FAIL TO UNLOCK device errors is that you must be in CHINA/ TAIWAN / SINGAPORE inorder to run you MIUNLOCK TOOL. for this purpose i used https://www.tunnelbear.com/ application and location SINGAPORE

5. unzip miunlock tool and run the exe file. LOGIN using your MI ACCOUNT

account will be validated for unlocking permission

since you recieved SMS, MIUNLOCK will ask you to CONNECT YOUR DEVICE FASTBOOT MODE / remember redmi goes to fastboot mode when POWER and volume down keys pressed and hold simultaneously for few second with jerk.

if everything goes right , the SMS + SINGAPORE LOCATION by TunnelBear; Miunlock tool will finally UNLOCK your device (WHEW)!!!!!!!!

INSTALLING TWRP / SUPERSU / LAZYFLASHER (ROOTING REDMI)​

YOU HAVE NOW UNLOCKED device RUNNING ON global or chinese DEVELOPER ROM MIUI8, (you can check the unlock status from about device section)

now

1. Download the stable MIUI8 from http://en.miui.com/download-298.html, and flash it with UPDATER TOOL the way you installed developer rom (as explained above)

2. once stable rom is flashed, boot your device and started using it by logging in to MI Account, google accounts etc. (again whole process takes 1 hr)

3. download TWRP IDO https://drive.google.com/open?id=0B31ivZaiUAGMVjZ6ekU4TEVveTA

4. download lazy flasher and supersu (as attached) and put it in the sdcard or internal memory!

5. switch-off device (REDMI3) and boot it in FASTBOOT mode by holding VOLdown+power keys.

FLASH TWRP by adb commands. please see this video! its EXTREMELY HELPFUL!! follow it by heart!

https://www.youtube.com/watch?v=G_P7Qd3kpAI

6. once you boot twrp as system readonly! make BACKUP in sdcard or internal memory!

7. mount system! and flash both zipfiles in sequence (A) superSU & (B) LAZYFLASHER ( lazyflasher disables dm-varity and prevent you from bootloops)

8. REBOOT in to SYSTEM! the first boot may take some time!

CONGRATULATIONS you have ROOTED REDMI3 / XIAOMI

warning

1. you will no receive any updates since system is modified by twrp hence you have to FLASH any updates in fastboot mode by downloading fastboot version of MIUI in future using MIFLASH TOOL / or XDA FLASHER

https://drive.google.com/open?id=0B31ivZaiUAGMdFBSYWhoMnJzakk

---any future flashing will void rooting and twrp, so you have to install twrp/supersu/lazyflasher after every update.

2. I skipped the EDL mode part! XIAOMI devices are highly unstable and you can brick them VERY EASLY!!!!

3. I skipped the part where you can replace twrp.img with kernel.img by naming it kernel.img in FASTBOOT ROM version using 7-zip. again you can brick your device very easly!

HOWEVER

4. if your boot locking request has been denied by MIUI team,,,, EDL is your LAST OPTION :(
