Q. Regarding the Chinese Version with Global ROM

[aser_elhbayeb]

I'm about to buy a Redmi Note 5 from AliExpress, but there are Chinese Version with Global ROM which the seller has to open the box in order to install the Global ROM. My question is whether the seller has to open (disassemble) the device itself in order to do Test Point Method and unlock bootloader then install ROM? Or there are other methods to install Global ROM on Chinese Version, and buying these devices are guaranteed to be not touched.

Anyone can confirm?

I already know that, but this isn't what I'm asking about.
I ask about the way AliExpress sellers use to install global ROM.

They do that way. They have VIP account which can unlock without waiting.
