oem locked : no possibility to boot or install any rom

[Navy31]

Hello experts,

My phone was rooted and bootloader unlocked. As I saw that android pie is available by OTA, I wanted to lock my phone in order to receive update (by OTA). So for that, I use command (fastboot oem lock). My MI A1 is now locked but i can't boot on it.
I guess the option 'OEM Unlock' is not ticked, that's why I can't install or flash any rom with Miflash.
I have message error : "failed (remote: oem unlock is not allowed)"
I tried a lot of advices found on different forums but none of them works.
If you have any idea how to unlock my bootlader, you are welcome.
Thanks guys !

Why you locked bootloader? Never lock a bootloader when phone is rooted (e.g. runs a custom boot image!)
You can install OTA updates also with unlocked bootloader, but you must unroot it first flashing the original boot image.

So you didn't update to Pie at the end, correct?

Please post the result of "fastboot getvar all"

You have an outdated fastboot version

Download the new from here

https://dl.google.com/android/repository/platform-tools-latest-windows.zip

The correct sintax is the first, fastboot set_active b

No effect. Still same issue

I can see 'current-slot:b' with 'getvar all'.

 

[jack_21]

No effect. Still same issue

The command was sent fine?

 

[Navy31]

The command was sent fine?

Yes

 

[jack_21]

Yes

Well, no ideas if not using EDL test point inside the phone (you need to open that)

Search on XDA EDL Mode Mi a1

Sometimes you can also use an USB special cable to do that
