Hello,i have the Redmi Pro but it was with fake os from the vendor.So i tried to unlock the bootloader as xiaomi suggested.I thought i have unlocked it,in the test menu it said unlock so i went to the next step.Downloaded SP Flash Tool,downloaded the stable rom and tried to flash the rom.
There was a problem with the cust.img file so i downloaded the suggested one for the fix but now it says that the img is a mismatch.
With a locked bootloader i can not flash through fastboot because it says it is not allowed,so does the XiaoMiFlash application.
No,the fastboot oem unlock doesn't work.
What can i do now?
Thanks in advance!

Just try to flash with older stock firmware using SP Flash Tool.
I had a similar problem and the older firmware gave it up unlock bootloader without any problem.
When unlocking with fastboot keep the order:
fastboot oem unlock
fastboot flashing unlock
fastboot flash recovery twrp.img
fastboot format userdata
Please change name of twrp-3xx....img to twrp.img

I used minimal ADB and Fastboot 1.4.3

The only solution that worked for was to flash stock 7.8.23 rom with miflash by connecting my phone in EDL mode and as I was still in bootloop I remembered that on nougat the command oem unlock could be done ... But when I finally managed to recover an operating system my imei was gone to zero 0 ... I was able to solve with software QST 2.7 and restore my IMEI ... A month of galère lol

Hi everyone,
I am the owner of an A2017G, unlocked bootloader.
I tried them all, but all of them and I can't get into fastboot / bootloader mode.
Ihave flash rom via MIFLASH and AXON7 EDL TOOL using rom Nougat and Oreo, but the result is always the same !!!
Do you have any ideas to help me, perpetuate?
Thank you.
Use miflash and flash unlock bootloader image by Turkdev, even in oreo it will give you fastboot menu.
I did this 3 days ago to relock my bootloader
Use this tutorial:
https://forum.xda-developers.com/axon-7/how-to/guide-unlock-bootloader-easily-t3704595
The reason you lose your fastboot menu because you unlock BL with another image (using Axon 7 EDL tool perhaps), but if you do unlock with turkdev image in tutorial, your fastboot menu will stay there

That's the point, you can flash the original firmware (the same one that is currently in your smartphone) even with locked bootloader. Try it before you say it can't be done.
Nope buddy boot loader is locked and system is already installed therefore mi flash tool ia unable to erase it cuz it shows me error cannot erase in lock state i tried flashing stock global rom through mi flash tool
exactly - flash stock rom for fastboot - I've done it multiple times

Try using some older flashing tool and if that doesn't work try using some older Chinese flashing tool and of course the fastboot firmware file in the format *.tgz*.
Ok so i found a mi unlock tool which is a modded verion of original tool what it does is bypass server authentication and unlocks bootloader of device thanks it wont connect to xiaomi for checking device unlocking permission and will unlock it
Hi,
I am having a problem trying to relock my bootloader.
i am selling my g4, so needed to remove my custom rom, flash stock and relock my bootloader.
I downloaded and flashed via twrp the stock 8.1 ROM on the g4 plus page. ( stock rom in twrp format)
That went fine.
Then I booted into fastboot , and entered fastboot lock command fastboot oem lock
It said the android image was not valid?
So I then entered fastboot flashing lock
it rebooted fine to the stock android , but now the bootloader warning says ''your device has loaded a different operating system'', and thens boots 8.1.
DO you think I should go back anf flash stock rom ( not a twrp flashable version), using fastboot commands, ending with 'fastboot oem lock' ?
Just dont want to brick it, as it is now sold!
Many Thanks for any help
pootler
P.S. the TWRP I am using is a custom one ( i think )

Use LMSA flash rescue option if you have a Windows machine
(Lenovo) MOTO Smart Assistant (PC)
then see

THanks for the reply.
Strange, thought I had already updated this
I went back to stock firmware and decided to flash with fastboot all individual files.
At some point, I got the same ''verification failed' but the command line suggested flashing system, boot, and ( something else, cant remember) again.
i did this this, and this time, no errors occured, and I had a complete install, with a locked bootloader, and no bootloader warning screen.!
Yay - result
Thanks again for your advice - I will remember it for the future.
