Is it necessary to unlock bootloader in order to get access to fastboot mode. - General Questions and Answers

Hi all Mi friends, and want to ask something. Is it necessary to unlock bootloader in order to get into to fastboot mode in Redmi Note 5 Pro. On pressing Volume down + Power button, it is not entering into fastboot mode rather it is rebooting to system.
Please answer my query about it.

I'm not a redmi user but did you try booting into fastboot mode via adb?

Thanks for your reply. But we have to enter into fastboot mode by pressing both volume down and power button but it is not happening. It simply reboots to system instead going into fastboot mode.

Nexus 5 Cannot Perform Unlock

I have Nexus 5 phone which was not turning on a few days back. I kept it aside so that battery drains fully.
Now when I turn on the phone, it is on Google Logo Boot-Loop. When I press Power and Volume Down, I can boot into fastboot mode.
In fastboot mode, the device says it is locked and i send the following commands:
fastboot devices
fastboot oem unlock (Select Yes on Screen and Confirm as well)
fastboot reboot
Click to expand...
Click to collapse
After this, ideally the bootloader should be unlocked, but the phone still remains in boot loop and when put into fastboot mode, it again shows device is locked.
I don't know what all is happening. Is there anything I can try now? Even fastboot boot recover.img is not working as phone boots into custom recovery for some time and then reboots automatically.

BLU Studio One Plus Unlocking Bootloader

Bought this device and everything works great and I have root. When I try to unlock the boot loader by going to "Developer Options" and checking the "Oem Unlock", I then
Code:
adb reboot-bootloader
At this point I do a
Code:
fastboot oem unlock
Which then the device asks me to use the volume buttons to confirm, Volume up for yes and volume down for no. The problem I'm running into is in fastboot mode it seems my volume up and power key are completely ignored. They work in recovery and in android but not in the boot loader itself.
I have tried unplugging the phone after sending the command over to see if that is a factor but it doesn't seem so. I'm only allowed to use volume down which denies unlocking the boot loader.
Another thing if anybody can get me a scatter file that would be much appreciated.

How did you root the phone?
Hoping for an answer to the bootloader question as well. For root I'm going to attempt kingoroot and replace with supersu

Can't enter fastboot mode after unlocked

I have unlocked my Huawei tablet using
Code:
oem shell
-> reboot fastboot
and later in fastboot mode:
Code:
fastboot oem unlock <pw>
now each time I am trying to enter the fastboot mode I get the
nasty "Your device has been unlocked and can't be trusted"
and throw me back to the regular boot.
Any idea what else I can try?
Code:
The info of my model is:
Named: Huawei M3 Youth
Model: CPN-AL00
Firmware: : MSM8940C00B056SP01M_AMSSJun28201718:26:30
Hardware ver: : SH1CHOPINAL0M-V2

Thanks for the reply but nop in HuaWei the gicky stuff comes with volume up button but in that case the
same thing I get the ugly text message and normal boot :/
Any other ideas?
Found it: you really hold the volume down and just plug the USB cable no other
actions required, it will turn on into the fastboot mode.
