XIAOMI Redmi Note 5 Pro [whyred] global fastboot ROMs bug

just to make sure no one getting the trouble i had. if you bought Xiaomi devices (not sure its the devices after Redmi 4a or every devices with miui 9.5) with the bootloader already unlocked by the seller or the distributor, make sure youre registering or linked your account to the device. because when whenever youre trying to install global fastboot ROMs with the lock option selected, the device will stuck at recovery with red notification at the bottom saying "the MIUI version cant be installed on this device". the thing is after youre installing fastboot ROMs and locking bootloader of your device, you cant install global fastboot ROMs no more and left with chinese fastboot ROMs or using TWRP. since youre locking your bootloader and if your mi account is not bound to your device, you cant unlock bootloader with the official unlocking tool (it will spit out error "current account is not bound to this device") and yes youre stuck with chinese fastboot rom. you can still bind your account after youre installing the chinese fastboot ROM and unlock your bootloader, but you still cant flash the global fastboot ROMs.
so heres my story for everyone who is experiencing the same issue
i bought my whyred with the bootloader unlocked from the seller/distributor (its a normal thing here, maybe) and i have no issue what so ever in first month i bought it. im changing ROMs with every custom ROMs i found until im bored and decided to installed global fastboot ROM then locking my bootloader. so im stuck on recovery with red notification at the bottom saying "the MIUI version cant be installed on this device" after i flashed my whyred with global fastboot ROM. i thought i was installed the wrong miui ROM, but no. since i locked my bootloader and i havent bind my mi account to the device yet i cannot install custom recovery and installed fastboot ROM no more. so i left with EDL mode then. i tried to enter EDL Mode with button combinations (since miui 9.5 this was disabled, cmiiw), deep flash cable (not working anymore), adb (well i flashed device and stuck, so i cant do adb), fastboot (nope, its locked) and i left with test point methode and this is the only working methode for you with the same situation.
so i flashed ten or so global fastboot ROMs i can find from different sources just in case i have a bad day. but nope, none was working. so i flashed chinese ROM and worked, i immediately tried to unlocked my bootloader but i now faced with 240 wating time. well i guest im stuck with chinese ROM for the next 10 days. the XDA and MIUI forum said that you should be able to flash global ROMs (not sure if this includes fastboot ROMs) again after unlocking your bootloader.

How to bind the phone with miui account. Explain the process in detail. Thank you.

[SOLVED] Lenovo VIBE K5 A6020a41 Bootloader refuses to unlock

EDIT:
fastboot boot and fastboot flash WORK even though
fastboot oem device-info shows thebootloader is NOT UNLOCKED.
If that still doesn't work try to flash some other compatible stock rom for your model with qfil and try the fastboot boot and fastboot flash commands again, don't care about unlock status, it worked for me successfully flashed twrp and a custom rom.
Hello!
My Lenovo VIBE K5 A6020a41 refuses to unlock its bootloader.
Output of fastboot oem unlock:
FAILED (remote: 'oem unlock is not allowed')
I have enabled developer settings, usb debugging and Unlock OEM setting.
I found some posts of people with the same issue and smartphone model and they said they fixed it by flashing another stock rom (they didn't specify which).
I have flashed two or three other stock ROMs with QFIL, one was for A6020a40 model and the other two were for my A6020a41 model.
Again, I enabled all the necessary settings and still couldn't unlock my bootloader, showed the same error.
Then I tried flashing TWRP through QFIL, but when I rebooted into it, Lenovo logo showed for a second and then a black screen forever, I also tried to see if adb was able to detect it as a device in recovery, but it didn't.
Then I managed to root it with KingoRoot(I know it is not secure and it is bad and all, but I just want to flash a custom rom anyway), so I installed the official TWRP app and an app called Flashify, both flashed TWRP successfully, but I couldn't boot into the TWRP again, Lenovo logo for a second and a black screen.
Do You have any suggestions please?
Thank You.

Try
Code:
fastboot flashing unlock
what is the appropriate command on newer devices.

Already did. This device supports the older one only. (Should support)

There are new guides on how to get volte if you want to try again.
[Guide] Easy method to Enable Volte (with root) on Tmobile and maybe other networks on Android 11 and maybe 10

I believe that relock is impossible and but to make the device recovery to installed status of stock rom keeping with unlock bootloader.
Please see my post. May make it help or not.
When I try to burn rom with TWRP, img burns but it doesn't start and zip gives an error and cannot burn.
When I first burned custom ROM (unofficial AEX), it did not start, so when I deleted the data from TWRP, it seems that I deleted things that should not be erased, so even if I burn it from the zip file, with the error message in the image below I...

Can't Flash TWRP

Hi friends, I own one Asus Zenfone max pro m1 and I recently wanted it's bootloader to be unlocked and I tried the unofficial method but didn't worked. So I chose the official method. It wasn't a good experience because I was successful after several attempts. Don't know why... But after installing and unintalling and then reinstalling the unlock tool several times somehow I managed to unlock the bootloader. Now it's showing fastboot mode instead of csc fastboot so I believe it's bootloader is unlocked.
But as I tried to flash twrp using Bugjaeger app from another phone(since I think I'm having issues with usb 3.0 port on my lap) it's showing "Flashing not allowed in Lock state".
How can I be sure to know if my bootloader is unlocked or not? And whatif I flash rom directly(using adb/fastboot) without twrp with Corvos OS? Will O be stuck on a boot loop?

I finally came to solve my problem by trying to unlock the bootloader again and again by official method. And after 3 attempts it was succesfully unlocked (unlocked properly). I could flash twrp without any difficulties and Im on Abhix Rog version now..

Can't use adb after unlock bootloader again

When I first time unlock the bootloader on my Galaxy S10e (Exynos), I can easily flash custom recovery and ROM, I've tried many custom ROM but then back to OneUI and locked the bootloader
Then the 2nd time I unlocked the bootloader but ADB isn't recognized my phone in download mode anymore, I've tried all kinds of drivers, please help me
(ADB still recognized in recovery and normal OS)
