Is it necessary to unlock bootloader in order to get access to fastboot mode.

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.

Oneplus 8 crashdump mode

Hey guys. So i attempted the fingerprint restore guide and it didnt work. I bought the phone second hand and apparently the guy before me unlocked the phone. Long story short, i used the restore tool to bring the phone back to stock state. All was well until i rebooted. Then i got a qualcomm crashdump. I restored again to no avail. I used msmtool to read a couple partitions and it looks like persist partition got corrupted. Only problem is my bootloader is locked due to msm restore, and i cant boot into rom to enable oem unlocking to flash my persist backup. Is there anyway to bypass enable unlocking. Or is there a way to restore persist with msm? Or qualcomm tools? Such a simple problem. Just no tool to flash persist from edl mode. Other devices like oppo have this ability. Why doesnt msm tool flash important partitions????
Did you sell your phone yet? I got stuck with Qualcomm Crashdump, no one at OnePlus knows anything about it apparently. So before the phone tries to boot, hold power + volume up + volume down. Release just in time you'll be in fastboot mode. It's a little tricky but it stops that Crashdump from happening and then you can access your device via fastboot. Then it's just fastboot flash persist persist.img, and whatever else you need to save your phone. You should be able to unlock it again in fastboot then flash TWRP (or just a flashboot version of the ROM) and go about your restoration.

Good day.
I have a LE2110 variant and install MSM with global variant, before this i can enter to fastboot but when i unbrick my devices, the fastboot option is impossible to enter always enter to recovery menu (ver 1.2).
Could you have any idea for this?

MSM version indian

PROBLEM SOLVED
My version is Kb2003, and i can't enter EDL mode, nothing will connect to device manager nor msm tool when I'm trying to enter edl. The phone connects only when I'm in fastboot.
I tried fastboot boot twrp, fastboot flash recovery twrp, fastboot oem unlock, trying to connect to adb when the device is booting. https://prnt.sc/ssdOX4J2QXRt here is the things that i've downloaded.
https://prnt.sc/d1ykZOXlB8Mn Here is MSM Tool, and device manager when I'm in fastboot, i have updated my windows but still my phone can't enter EDL Mode...
EDIT: https://prnt.sc/a9Y0R9wWbMWX which qualcom driver should i choose? i can't find qloader 9008 ( I'm in fastboot mode rn)
I have searched for two days straight the xda forums, reddit, youtube, and other forums, please help me...
