Is there any possible way to downgrade to miui 9.5.4 without unlocking bootloader as it takes 15 day to unlock

Hello everyone..
I recently got my Redmi Note 4 SD, its the 4/64GB variant and the device is classy I must say. However, since the last update, my device is having RAM issues and above all, heating issues. What I'm trying to know is can I flash the outdated version via fastboot method without unlocking the bootloader?
I am on the 8.1.15.0 version (Indian Variant) and I have the 8.1.10.0 version, I just want to rollback to it.
I hope there must be a way to flash stock ROMs without unlocking the bootloader. And also, if I unlock the bootloader and flash the stock ROM, will the bootloader get locked again or would stay unlocked?
A step by step guide would be highly appreciated.
ThankYou
Isn't there anyone who can help me out with this?
You need to unlock bootloader to downgrade or flash fastboot ROMs. You cannot downgrade from Updater app

Fastboot method is for you, and there is no need to worry about ARB, and after unlocking bootloader you'll also be able to install xiaomi.eu!
Hello!
I recently bought the 8" M5 without realising the hoops I'd have to jump through to unlock the bootloader.
After getting lucky and being able to downgrade to FW163 I have successfully unlocked the bootloader and I've been running a treble rom. Yesterday I wanted to try out an OpenKirin rom, so I flashed the stock EMUI 8 firmware in order to then flash the OpenKirin rom.
After flashing stock I realised my bootloader was relocked - not a big issue as I still had the unlock code and I was still on FW163.
My question is - if I upgrade to EMUI 9 ota will this relock my bootloader the same as manually flashing 163 did, and if so, will I still be able to unlock on higher FW versions since I already have the unlock code? As far as I'm aware the issue we were faced with was actually obtaining the unlock code after official support ended, so in theory now that I have the code I should be able to unlock on any firmware, right?
Thanks!

Theoritically said, yes, because the xloader have those kind of hexes that stay the same even after updating the firmware and the xloader and as additional info, I'm now on Omnirom for EMUI 9 vendor from Openkirin team and I can download the EMUI from eRecovery without getting my bootloader locked
Hi,
I am a first time Xiaomi user and just got the Mi 10 Global version. I tried manually installing the official global MI 10 Miui 12 ROM, but the update failed as it couldn't be verified. Please take a look at the screenshots..
I can't update it via fastboot neither, as my bootloader is locked and Xiaomi wants me to wait for 168 hours (7 days!) to try again.
Any help will be greatly appreciated.
Don't update the **** miui 12

Because it is a Vodafone branding. You have to wait till Vodafone release the update.

So the VF at the end of MIUI version number means Vodafone?
If that's the case I might as well go and unlock my bootloader, flash the unbranded global rom and relock the bootloader.
Do I loose anything by unlocking and relocking the bootloader? I had Samsung phones before, where unlocking the bootloader would trip Knox and invalidate your warranty.

Yes VF is Vodafone branding. If you unlock bootloader you will loose your data. So make a backup.

So in the end I flashed it with Xiomi Tool V2 and I didn't need to unlock the bootloader.
