Fix MIUI themes on theme store not support in MIUI 10

 Must needed-

• Device running MIUI 10 beta or global
• Mixplorer app

As we know MIUI 10 is awesome but no MIUI 10 themes Which are available in theme store are not fully supported, for example theme BLACK JOKER[DD] which is a theme which have WhatsApp module that can convert ordinary WhatsApp into a dark WhatsApp but in MIUI 10 after applying BLACK JOKER[DD] theme Nothing is change in Whatsapp, it remains the same, as show below-

But after useing my method BLACKJOKERS[DD] theme change the WhatsApp into a dark one
As shown below-

So, by my method you can have MIUI 10 support on themes which are already available on theme store, Except Notification panel because it is redesigned but status bar works
STEP 1.
First go to the settings app>Go to advanced settings>Go to buttons and gestures shortcuts>Close current app>Choose long press back button
As show in video down below-

STEP 2.
Now, open the themes app, download the theme you want when the downloading is complete you have to force stop the themes app by press and holding the back button before it Imports the theme
As show in video below-

STEP 3.
As shown in video above,
Now open Mixplorer app and tap on three dot menu and select show hidden files and select global and press ok
Now go to your Internal storage>MIUI>theme>.download (its a hidden folder)> and there you find the downloaded theme which have extention .mtz now open the .mtz file>open Description.xml>Choose code editor> find the line "<uiVersion>6</uiVersion>" and replace it with "<uiVersion>10</uiVersion>" it will tell MIUI 10 that this theme is MIUI 10 supported, Now tap on the save button and Open themes app> Go to offline themes> wait for import the theme, now your theme is listed automatically in offline
As shown below-

themes and all theme things will work which are not working before except Notification panel because it is redesigned
