Greeting , MIUIers

This thread is divided into 2 part

- Flashing TWRP & ROOT (& INSTALL XIAOMI.EU)

- My active development project for Redmi S2/Y2 (YSL)

Today , I will be showing you how to flash TWRP and root the Xiaomi Redmi S2/Y2 (YSL)

I took time to make this and sure that it is noob friendly.

You can not blame anyone if you bricked your phone, It's all your own fault. Please done it with caution.

People who do not know what they are doing right now please leave this thread alone.

!!! Unlocking & Rooting phone will lost your warranty !!!

(Re-locking & flashing full rom by fastboot should give your warranty back)

Requirements :

- Unlocked Bootloader

- Workable Brain

- Common Sense

- TWRP

- Magisk

- ADB & FASTBOOT

- ADB & FASTBOOT DRIVER

- Xiaomi.eu Rom (Optional)

https://xiaomi.eu/community/forums/miui-rom-releases.103/

Note:- You can flash it on any miui rom.It is safe to flash.

and for boot into recovery wiping of data not needed.

but if you flash ( I said flashing) on xiaomi.eu MIUI roms then to decrypt internel data you have to click on wipe data and then it will ask you something you have to simply write "yes" and then your internel data will be decrypted and you can see all the files of internel data in twrp.( Decryption of internel storage is only supported by xiaomi.eu roms )

But if you flash it on any other MIUI rom then it will not decrypt your internel storage (So no need to wipe data). To flash any .zip or .img file you have to put that file in your sdcard so that you will flash it through twrp.

And note that if you only boot into twrp then you dont have to wipe data but you have to put your flashable files in the sdcard.TWRP will not be there once you reboot.It only will be seen when you again boot into twrp through cmd.and you will get ota update as well if you only boot into twrp because when once you reboot your phone you will get your stock recovery not twrp.

I am again saying booting and flashing are two different things.

!!! UNLOCKED BOOTLOADER REQUIRED !!!

Let get start,

Copy the twrp file into your ADB&Fastboot folder.

First of all , Prepare your phone in fastboot by

- Power + Volume Down

- adb reboot fastboot

Then type "fastboot devices"

It should return something.. (Your phone)

If it didn't ( Please go read #1 Solution in the end of the thread

After that, type

"fastboot boot twrp-3.2.1-0-ysl.img"

If you want to temporarily boot twrp

or type

"fastboot flash recovery twrp-3.2.1-0-ysl.img"

If you want to flash recovery.

Then, You should see your phone entering TWRP

You will be prompted

"Please enter password to decrypt your phone"

(Please read solution #2 at the end of the thread to permanently disable encryption)

Don't enter password....

Click cancel then go to wipe

Then "Slide to wipe" ( If there are errors please go read #3 Solution in the end of the thread )

Then advanced wipe and wipe Internal Storage

After that, click "Install" then click "select storage"

and select External Storage / SD Card and click

"Magisk.zip" and "Install This ZIP" wait until the installation finish then click "Reboot Device"

Congratulations, You have rooted your phone

Solution Part :

#1 : My device is not founded in fastboot...

Answer : Did you even unlock your bootloader...

#2 : Permanently disable encryption

Answer : Please make sure that you done rooting your phone then flash xiaomi.eu rom before flash please wipe all of your partition except EXTERNAL STORAGE (SD CARD) then flash Magisk.zip again

What is xiaomi.eu rom?

It is a modded miui rom based on CHINA and have OTA update supported... Also, It disable encryption

#3 : Can't format

Answer : Please reboot your phone into fastboot and start the process again...
