I think that this website to make a suggestion. (You can use google translate from Thai to English)
i said that you must be download xiaomi mi 5 global developer rom not xiaomi mi 5 china developer rom because your current rom is global rom not chaina rom.
you download full rom 1.3 G in computer and put it in your mobile.
then you update by updater in menu update system.
you can see three...
You download Global Stable Version: V7.5.6.0.MAACNDE (MIUI7) and put it in your phone then install by updater. When already you can unlock and flash another rom.
