See newer post hope you can also fix the problems, thanks a TON for our Rusians community 4Pda..
The problems solved, nom i'm abble to unlock my devices (Mi 5s). gor everyone bought the secondhand units, beware this problems might comes to you.
and this method may also posible to work on any Xiaomi devices, please report if this method works on any other devices,so it can help more people with the same problems.

*What i've done on my capricorn, loging out the MID,enabling oem-unlock before flash.
1. latest global developer fastboot rom.
2.extract the rom.
Browse and find the "rawprogram.xml"
Use notepad++ to editing the line add "persist.img" on the line.. check the sparse value check it's set as true.

3. Use miflash to flash the rom,enter edl mode with testpoint ...wait till flashing done ..settup the phone (don't know if its the matter, i finished the settup without sim, use wi-fi)
Signing in enabling developer mode and miunlock status bind the account and done, just wait some times to get approved.

Try to refresh persist.img through MiFlash, I did it. I made a short instruction in the Russian forum, but I do not have the opportunity to insert a link here.

helped me. before that I tried many ways that did not work on my mi 5. at the time of unlocking the phone through the test point mode, the firmware was downgraded from miui 10 to miui 8. (which did not help) then I left the account and requested persist.img. after which the phone immediately became attached to the account, and later the miUnlock program was unlocked immediately (without waiting, the account I had since the first versions of miui)
