H:\New folder (3)\A\platform-tools_r30.0.3-windows\platform-tools>adb reboot boo
tloader
error: no devices/emulators found
H:\New folder (3)\A\platform-tools_r30.0.3-windows\platform-tools>
All drives & ADB are installed
No phone detection when fast boot
sorry; cannot speak english ...

This phone doesn't respond to fastboot unlock command.
First you need to enable usb debugging and allow OEM unlock in developer options.
Then you just flash TWRP recovery , by using Qualcomm QPST flash tool.
Once you have TWRP installed , flash Magisk to root the phone.
Search the threads here , there are a few Twrp/rooting guides that you can follow.

Unlocking bootloader unofficially?

Hey guys! Is there any way to unlock Redmi Pro's bootloader without waiting for permission from Xiaomi? Have anybody found a way to bypass it?
easy, first make sure you have spflash tool and a working fastboot rom (just in case of trouble)
Next make sure your computer has working fastboot and adb.
Enable USB debugging on the device.
Enable OEM unlock in the Developer options settings on the device.
Connect the device to the computer through USB.
From a terminal on a computer, type the following to boot the device into fastboot mode:
adb reboot bootloader
Once the device is in fastboot mode, verify your PC sees the device by typing fastboot devices
If you don't see your device serial number, and instead see "<waiting for device>", fastboot is not configured properly on your machine.
From the same terminal, type the following command to unlock the bootloader:
fastboot oem unlock
Device is wiped & unlocked & no OS
Now flash twrp, reboot into it and copy xiaomi.eu rom on card & install
Good luck

Sadly there is no oem unlock option in developer options. I'm on MIUI 8.1.2.0 Stable (MHQCNDI)
EDIT: i just switched to Developer ROM and still nothing.
sorry, my mistake i use another laguage, activate usb debuging , conect to the pc and run adb , if some permision asked alow
I can't unlock it using fastboot oem unlock since it's mediatek device =/ When I try I get
(bootloader) Start unlock flow
FAILED (remote:
Unlock failed - Err:0xffffffff
)
finished. total time: 0.016s"
Click to expand...
Click to collapse
i unlocked that way, maybe you do something wrong
try another way without unlocking try flash twrp with spflash tool
Do you remember what miui version did you have when you unlocked this way? Maybe I can roll back to it and then try again. Were you using developer or stable rom?
i was on fake/vendor rom this i thinlk http://blog.geekbuying.com/index.ph...ndroid-6-0-smartphone-firmware-212302-161109/
Crissz, your bootloader was allready unlocked when you received your phone. You cannot do a simple oem unlock via fastboot with a xiaomi phone. It's a fact..
@KarKlim please try fastboot oem unlock-go comand too
This method does not work as many say
(bootloader) Start unlock flow
FAILED (remote:
Unlock failed - Err:0xffffffff

Maybe try with a new xiaomi account with different sim card.
And then from a different internet ip, from your friend or something.
I have no idea how they collect data or what. I'm just guessing here.

Bootloader question on 906k

Hello,
I have a galaxsy s5 906k and I've been reading on how to unlock the bootloader as I'm trying to install Remix OS and it seems I've come across a lot of misinformation.... and if possible can someone tell me what exactly I need to unlock the bootloader, as I can't find a list of the appropriate tools? Do I need twrp for my specific device?? Some have said yes and some no.
My phone is already rooted.
Also post unlock bootloader question, can I use the 900k rom from remix to install on my 906k?
EDIT**
I can only boot into download mode, not fastboot mode. adb devices returns the device, but fastboot devices returns nothing. Tried adb reboot-bootloader`and it just shows waiting for any device.
These all boot into download/odin mode!!!!!!
adb reboot download
adb reboot bootloader / adb reboot-bootloader
fastboot oem unlock
fastboot flashing unlock
Only one that boots into recovery mode! Then I go to Reboot to bootloader and it comes back to recovery mode!!!!!!!!!!
adb reboot recovery

How to unlock bootloader and install TWRP recovery on Yu Yureka?

My friend who owns a Yu Yureka has been hounding me for a couple of days to install a custom ROM on his device because he has seen me using custom ROMs on my devices.
Problem is I'm only familiar with Motorola and Xiaomi devices and to some extent, OnePlus devices because I've used/owned these devices in the past/now.
So can anyone guide me on how exactly should I unlock the bootloader and install TWRP recovery on this device?

Power off your device
Hold volume up and connect usb cable
You will be in bootloader
Type this command

Then flash recovery
fastboot -i 0x1ebf flash recovery twrp3.1.x.x.x.img
