I'm very sorry, I'm a noob and it's still not very clear to me if it's a good idea to buy a so called 'Official International Version' as linked in the original post. I require B20 for 4G to work in my country. Is this really an official ROM or is this some kind of unsafe reseller ROM? Is it safe to update this so called 'Official International Version' without losing the B20 support? I don't really want to unlock bootloader. I'm extremely confused right now .
Could you provide screenshot of this app https://play.google.com/store/apps/details?id=com.qtrun.QuickTest please?
It's only vendor's marketing. It's actually just a version on sale at Mi Hong Kong website, for some reason they decided to unlock B20 for hong kong. I own one, bought on *********** and it works.
Hi. You can order it from **********. Look for the "international version".
Available variants are color Grey with 32 GB of Ram and color Gold with 16 or 32 GB of RAM.
They have different warehouses also, so you can pick, if you want to ship it from China or from Spain.
I ordered from China via airmail and received it 16 days after my order. Its a great phone.
I was (theoretically) able to unlock Band 20 with QualcommTool.exe according to the Info on xda-developers.
First put phone in Diag mode: In the shell input as Admin:
setprop sys.usb.config diag,adb
-> run QualcommTool.exe as Admin
-> with right mouseclick first activate an then connect the diag-com port
