Cannot unlock bootloader again after using Clean and lock option in XiaoMiFlash

Hello.
A friend ask me to install Lineage OS on his Mi8 so we asked for BootLoader unlock, wait about 15 days, unlock it and install Lineage OS.
But he decide to try Havoc OS because of some missing features in L.OS but flash goes wrong.
I manage to reflash MiUI 8.11.23 to get a usable phone but I didn't notice the option in the lower right end of the screen and I flashed with "Clean and lock" option
So the bootloader is now lock again but we cannot unlock it as when I use myflash_unlock utility, I'm facing this error :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Is it possible to unlock again the phone ? Do we have to wait for a some days (like when you first unlock it) ?
Thanks.

If you used your xiaomi account to unlock it, then you should be able to do it again instantly (something similar happened to me and I could re-unlock it without problems). If you do not have the account that was used, you have a big problem and only one solution: go to a Xiaomi store and ask for a reparation, they have EDL accounts and that will fix your problem. You can try to find a EDL account on internet, but it is almost imposible.
If you are using your own account, maybe you can try with a wipe data, but I am not sure
PD: remember to check if you have activate the developer options of USB debugging, etc. on your device

Unlock BL - already locked to another Mi Account

Hi,
I've just bought a secondhand Mi 9 (my original Mi 9 screen broke when I dropped it ), but when trying to unlock the bootloader, I get this message:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
which google tells me means the phone has been locked by account 157***980 'by looking for the phone and cannot be unlocked'.
I take this to mean that the phone was linked to the Mi account 157***980 by the original owner, and therefore can't be unlocked using the Mi Unlock software.
Is this right or is there any way around this? I'll have to return the phone to the ebay seller I bought it off (I don't think they were the original owner, so wouldn't be able to delink the phone).
Just to be clear, this isn't a question about circumventing the wait time to unlock - it's asking about the above situation.
Thanks in advance.
----------------
EDIT: It turned out that was my account - I seem to have two, one associated with my phone number, and one for my email address - trying for a third time sorted it out for me. Gah. Mods, please feel free to delete this thread as I don't think this question will be useful to others.

Redmi 8 can't start

Hello all
I have a problem with my phone. After starting the day all normal, tried to install an app for my job (KeyAccess Pass) to enter the building and etc, left my phone by side and continue to work. After some time, I've realised the my phone was off, tried to power on and since then stuck in the screen bellow.
More info: probably bootloader locked, no root, stock rom MIUI 12.5.something updated with OTA almost 2 months before. Tried power + volume+ and power + volume-, nothing different.

if you still have an active warranty, id suggest to check in at a service center.
try accessing safe mode (power on then voldown). most of the different boot modes require a 2nd vibe tick, is it still locked out? if you do get in, try formatting data via recovery. if not, yeah the service center is literally the only way with a locked bootloader.

Thanks for the reply. No warranty for me, and I'm locked out yet, so I will think a bit if I will go to the service center or buy another phone...

I posted two Screenshots, One is my current one and the other one is which i want to install, I want to make sure if it is ok to move directly from. Miui a11 to a13, or there will be some other process, it would be great if you guide me with the steps in both cases
Thanks

Yes you can directly move to A13 Custom ROM.
But before you can do that, you have to do the following:
1. Enable Developer Option.
2. Unlock bootloader (OEM unlocking)
3. Create MI account and follow instructions for unlocking request.
3. Wait for one week. Xiaomi will authorize the unlocking.
4. Use the Xiaomi unlock tool.
5. Enable USB debugging.
6. copy the rom.zip in your SDCard.
6. Using ADB , boot to TWRP.
7. from TWRP, install the TWRP recovery image (optional)
8. follow the instructions for flashing A13. Normally you need to wipe DATA partition.

Bootloader

Hello, people of the Xiaomi Mi 9.
I have owned this device for a while now and I have a problem that I would like to share with you.
A short time ago, I closed the phone's bootloader to make it like new... And it was a serious mistake.
I bought a new mobile and thought about using the old one as a backup.
This endorsement should have:
- Bootloader unlocked
- Root activated.
I must add that that device had a Mi account that belonged to me and I deleted it.
After doing that, and closing the bootloader, using the precious command of:
- fastboot oem unlock
Appears the next message:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I have tried to use the Mi Unlock software but when I enter my new Mi account and press the Unlock Now button, I get the following (What is covered was the ID of my old Mi account)
I have tried to insert my SIM card, add the new account, activate the OEM unlock option and try to unlock the bootloader using Fastboot... But I get what I indicated...
