Hello guys, i hope im in the correct section for help..

I have a redmi 4 prime which i have send to China for hardware repair, but before that i was log off my mi account from the device, after it came back fixed i couldnt sign in anymore to mi account, i get the error "couldnt check device security info"

I went to about phone, IMEI information and i found out that they changed IMEI and MEID its not the same like on the box.. I guess they replaced my motherboard..

Now i have 2 questions, if i replace the IMEI with the old one my issue will be resolve?
Is is safe to unlock bootloader with this method since i cant connect to my mi account to unlock with official way? https://forum.xda-developers.com/redmi-4-prime/development/xiaomi-redmi-4-prime-pro-unlock-t3590006
