in fastboot mode run commands :
fastboot oem get-build-number
fastboot oem get-product-model
fastboot getvar vendorcountry
fastboot oem oeminforead-CUSTOM_VERSION
fastboot oem oeminforead-SYSTEM_VERSION
and post the results.
Some might fail, so don't worry about it.

Why would a private seller purposely activate demo mode? That makes no sense.

Well the seller probably have picked up this from the trashbin outside a mobile phone store, seen it has demo mode, and gone on ebay to enjoy scamming people.

How can i use EDL?
Sapper Morton said:
Since your bootloader is locked, and there's no proper system.img in slot B, you must change it to slot A; however it's not possible in locked state, first check if it's possible to unlock, by running:
Code:
fastboot flashing get_unlock_ability
If the output is 0, you cannot unlock, and EDL is a must, otherwise, the output will be 1, therefore, unlock is possible, then proceed with the following steps:
Code:
fastboot flashing unlock
Code:
fastboot set_active a
Code:
fastboot flashing lock
As explained above, it's not possible to change slot without unlocking the bootloader.

Is there any way to oem unlock without going to Debugging Mode -> OEM enable?

EDL mode and authorized Mi account. You should contact your nearest Xiaomi service center or use some online service (you might need to open your phone yourself in such case).

oeminfo for C675?

Does anyone have the oeminfo for C675?
Please help if you have one. I don't see it in the full-OTA zip as well...
Thanks!

oeminfo cannot be obtained from the firmware, only from the phone (e.g. TWRP backup).

Btw, a few years ago, it was possible to use the Oeminfo-tools+0.13.exe application by @k1ll3r8e to read and edit oeminfo (only 64 MB version). But I don't know if it still works. Try asking the author.
Exactly! I found this 2021 updated version and I'm trying it...will update on the progress.

Yes, it was successful and it relocks.....I unlocked it again after every trial...

Looks like I need to change build number to something like: 9.1.0.112(C675E5R1P3T8) to make it work....is that correct?

in my opinion you need to overwrite oeminfo correctly, build number will be corrected automatically. And don't forget that you currently have an Oreo there...

P20 LITE bricked

Hello,
I've been battling for two days on a damn Huawei P20 Lite (ANE-LX1) which is totally bricked.
I have a page with red writing that says System is damaged but nothing happens if I press Volume Up etc.
So I tried to flash by EDL mode and I'm afraid I don't really understand how it happens, I can't do anything but it is noted that the bootloader and the FRP are locked.
I have an EFT Pro dongle, I tried to unlock it, I succeeded but it's temporary unlocking and it's useless to me.
I leave you the answers to the various Fastboot commands hoping that you will be able to help me.
Thanks in advance
