No Update Possible

[Jeunx]

Hello,
I root my MI4c of "MIUI 8.2by xiaomi.eu 7.2.9 Beta" in January.
Now, i want to update my MI4c.
But it was not possible.it seems that my bootloader is locked again and i can not start the recovery mode (e.g. with loud+ and power on). A factory reset on my phone is also not possible.
Want is problem with my phone?
I found no answer in the internet till now.

Can anybody help me?

Thank you in advance,
Jeunx

That was my problem, it doesn't worked.

Cancelled after 50% (Couldn't verify device).

But why does my account didn't work now?

With the MI Unlock tool 2.2.405.5, i get the information after 50% "device unlocked, no need to repeat unlock".
???
I am all mixed up

Did you unlock it with the official method before? Are you using the same account as you used then?

I also had this problem. To make it more worse, I had a network error in the MIUI UNLOCK site. To overcome this I had to install a VPN program (tried several virtual countries) and combine this with this procedure:

It worked and it was my last option after a lot of work. I hope I can help someone whit this.
