Clean proccess to Unlock bootloader,And Root Yuphoria
How To Unlock Yu Yuphoria’s Bootloader –
Extract the adb_fastboot file in a new folder in your C:/ drive.
Power Off your phone.
While continuously pressing the Volume Up key, connect your phone to the PC/Laptop via USB cable.
You will get a black screen stating ‘Fastboot Mode’ at the middle.
As soon as you plug your phone into the PC, windows will start installing drivers all by itself. Please wait for the installation to complete.
After the drivers have been installed successfully, go to the folder where you have extracted adb_fastboot file.
While pressing the Shift key on your keyboard, right click in the folder and select ‘Open Command Prompt Here’. The command prompt will open up.
Now type the following command to check if your device has been detected in the fastboot mode.
fastboot -i 0x2A96 devices
You’ll get an error if the drivers aren’t installed successfully. However, if you don’t get any error, you may proceed to the next step.
Now, run the following command to unlock the bootloader.
fastboot -i 0x2A96 oem unlock
Now, run the following command to reboot your device to system.
fastboot -i 0x2A96 reboot
Now, that you have successfully completed the first step, let’s jump onto the next step.
How To Hotboot CWM Recovery –
Hotbooting is way of temporarily introducing a custom recovery in your recovery partition. As soon as you reboot your device, the custom recovery will be replaced by the stock cyanogen recovery.
Now, since we have to flash supersu zip from a hotbooted recovery, you first need to copy the supersu zip from the rooting kit to the sd card of your phone.
Now, copy the yuphoria-cwm-recovery file from the rooting kit to the folder where you extracted adb_fastboot.
Using the same old method, go to fastboot mode and open command prompt. Now, type the following command.
fastboot -i 0x2A96 boot yuphoria-cwm-recovery.img
The above command will boot your yuphoria into cwm recovery.
How To Root Yu Yuphoria By Flashing SuperSU –
Now that you are in cwm recovery, to flash SuperSu zip on your device, you need to follow these steps-
Select ‘Install zip from sd card’ and navigate to the place where you copied the SuperSU file.
Now, select ‘Yes’. It will flash the SuperSU zip on your phone.
You should now have root access on your phone. After rooting, it is recommended to install Busybox.
Download Busybox installer app from playstore and follow the instructions to install it.
Congratulations, you’ve rooted your Yu Yuphoria! Enjoy!
Note you can even flash Twrp.img

Yes it will erase ur internal memory ...
So better to make a backup of it....
---------- Post added at 08:02 AM ---------- Previous post was at 07:58 AM ----------
Sir can I use this method of booting in a recovery temporarily to do all the things a permanent recovery can do .....
Like can I make nandroid backup from it , can I install xposed from it without crashing and bootlooping , can I use apps like ROM manager ..........
I have already rooted and unlocked my bootloader of YU yuphoria by these steps ......
Thank you

Guys I'm on global Miui 8 Global 6.7.5 beta. I tried to root and install twrp using mi4i rooting toolkit version 4. But it doesn't work. Previously on miui6 and miui7, I can root and install twrp using the mi4i toolkitV4. But now it doesn't work anymore when I upgraded to miui8.
Does anyone knows how to root miui8 global 6.7.5 beta?
Rooting
First you have to enable developer options. Then in developer options under debugging section turn on USB debugging and Fastboot Mode.
Then download TWRP. Rename it to twrp.img for ease.
https://dl.twrp.me/ferrari/twrp-3.0.2-0-ferrari.img.html
Install fastboot and adb drivers.
http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
Download root zip file, and place it on internal storage.
https://download.chainfire.eu/696/supersu/
Open the folder on PC where twrp image is downloaded. Hold shift and right click on the window(not the file or folder). Then select open command window here. CMD will open.
Long press power button and volume down to boot into fastboot mode, connect it by USB.
Type in CMD: fastboot devices
If it shows a device is connected you are good to go! If not verify if the drivers are properly installed.
To just root and preserve Mi Recovery for OTA:
Type in CMD: fastboot boot twrp.img
this will boot into twrp to flash supersu.zip file and reboot.
To flash TWRP permanently:
type: fastboot flash recovery twrp.img
then reboot by long pressing power button then open TWRP by power button + vol up. Then flash supersu.zip

Yape!
Thanks for the article - will update and root tonight
The process:
update via OTA (hate this as my 16GB is insufficient - love all things M1 but hate the lack of external SD capability)
Reboots - it enters my old TWRP, and auto install update
Once it installs, and auto powerup, I turn on "fastboot mode" (developer option was already on) - a pain in the a55 due to the security prompt...
Power-off the device. Reboot to fastboot mode as per instruction above
I chose to retain M1 recovery, and so fastboot into TWRP to install SU.
Reboot
Tested with titanium backup - root works!
Thanks!!!
Love the new notification drawer, and memory management...
can i root my mi4i without instal twrp and still habe ota update if my phone rooted ?
thanks
Yes.
The OP posted 2 methods for using twrp near the end of his post.
For v7++, I could always ota despite having twrp onboard, instead of mi recovery. Not sure about this recent v8. Hence I used the first method above, preserving my recovery. Also, from my history of use. I never use twrp or recovery anymore, after rooting. No point having recovery backup as mi issues updates ofyen. I use titanium for backup of third party software only. Even then this is redundant since ota preserves software.

Are you sure you installed ADB Fastboot drivers? and make sure you 'cd' to the directory where twrp.img is located or else it will say the file is not found.
You need to put the both fastboot and image files together in the same directory. Then open a MS prompt in this directory, and type the syntax to flash.
twrp not found??

Hi,
I manage to flash TWRP (i.e. sending recover =OKAY & writing recovery= OKAY).

TWRP 3.0.2 for Acer Predator 8 ported by Ruben. - If you like my work please donate here, it will also give me a boost to make more things for this device : https://www.paypal.me/RubenCraveiro
----------- -----------
IMPORTANT NOTE ABOUT ROOTING AND UNLOCKING BOOTLOADER:
After flashing TWRP 3.0.2, use the SuperSU 2.46 flashable zip, do NOT use latest version or will result in a bootloop. Good Luck and have fun with rooting. Unlocking bootloader will delete all your data, so please make a backup first. Thank you.
----------- -----------
CREDITS
And also, before anything i would like to say thanks to @arjaylzo for telling me the name of a device with TWRP which helped making this update possible.
REQUIREMENTS
1- Fastboot/ADB Drivers and ADB folder
For drivers: http://adbdriver.com - Download ADB Driver Installer (universal) from the website, extract it, connect device it should detect device(if not, enable USB Debugging and reconnect), and press install, it should install drivers.
For ADB Folder: download this and extract to your main drive(C:/): https://goo.gl/ZTrfBb
2- Unlocked Bootloader (you need requirement 1 to do this)
Instructions for Unlocking bootloader: Go on settings, about device, press build version several times till it says your a developer, go back to settings, press Developer Options, and enable OEM Unlocking. Power off, then press at same time Power and Vol+ button, then connect to pc and open a cmd and write cd c:\\adb and write fastboot oem unlock, then accept the prompt it will give on tablet, and follow the rest of the steps.
----------- -----------
New TWRP bugfix update! Now you can flash stock rom on TWRP without bricking! Download Page updated!
----------- -----------
BUGS:
1- adb shell command needs to be sent before system partition is mounted or it will give an error, after doing adb shell you can mount system and do all the modifications you need.
2- You cant flash any img on twrp it gives an error, im trying to fix.
3- Backups do work, but everytime twrp restarts, the device name seems to change (which means that on /TWRP/BACKUPS/devicename/backupsinside/ changes every reboot so you have to go get the backup inside the old devicename folder and put on the new devicename folder).
----------- ADITIONAL NOTES -----------
Im leaving an unsecured boot image because system seems not want to boot android if anything seems changed. So please if system does not boot after flashing twrp/rooting, flash the unsecured boot img on fastboot
----------- -----------
Steps TO INSTALL TWRP AND ROOT
1. Download and extract the files: https://drive.google.com/file/d/0BxzG5iupOOSKNTdlRC1Wd0VmTlk/view?usp=drivesdk
2. Power off the tablet.
3. Enter fastboot mode by pressing the power button while holding down Vol -
4. Open up command prompt and navigate to the directory where fastboot.exe is located.
5. Pass the following commands:
fastboot flash boot unsecuredboot.img
fastboot flash recovery TWRP.img
6. Reboot into recovery (TWRP) and install SuperSU v2.46.zip

C:\adb is where my adb and fastboot commands are.. on the downloaded files from Step 1 only the SuperSU zip is needed on the tablet so that you can flash it later on with twrp, the rest you leave on pc and use fastboot to flash TWRP, unsecured boot image, etc...

make sure you didnt put a folder inside the adb folder instead of the actual file and make sure your writing the right name of the file..

If you flash stock rom, i think you have to reinstall stock recovery, the rom itself already brings stock boot.. after flashing stock recovery it should boot since no modifications have happend

On step 4 You need the fastboot files, (adb & fastboot) just search how to install adb and fastboot drivers, choose the directory where to install them and place the needed files inside that folder and open a command prompt on that folder so you can flash the files.

That means adb drivers arent corrently installed, but i can see you have the folder with adb, all you have to now is download this(drivers): http://dl.adbdriver.com/upload/adbdriver.zip
Extract and open the software eith the tablet plugged in, it should tell of drivers is installer properly or not, and if not you can install, after installing it should work on the cmd the commands..
I accidentally formatted all partition and now only have a TWRP. The TWRP only shows the start screen when i go to recovery.
Adb devices show me the device detected. I did a adb push and moved the stock rom 5.1.11 and my twrp recovery to the sdcard using the command adb push. I am struck here because i cannot get to the twrp screen which gives you option to install/wipe etc.
Can somebody please guide me if there is a way to recover or install the .zip files I have copied to sdcard. Thanks in advance
You need to fastboot flash the default stock rom, and then re root/install TWRP etc etc
Thank you for your response. Will that be adb fastboot flash stock.zip ? I am not sure if this would mess it up hence please confirm. Also, will it work if i use the fastboot to install twrp again and then flash the stock rom using its menu.

You need to go to this thread... https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665
Download the version of OOS you want (5.1.11) and unzip the contents in to a folder and run the flash-all.bat file and let it install to all partitions. Just follow this instructions in the thread and you will be fine.
Thank you so much for your response, but when I run this command I am getting " Waiting for device" option. I am only able to boot into twrp. I see the teamwin loading screen and its struck there. I am able to run adb commands and adb device shows the device details. I was also able to push the stock rom.zip through adb push command to /sdcard.

You need to be in fastboot mode.
Either adb reboot bootloader from inside android or from a powered off phone, hold Volume Up and power on.
