With MIUI4 ported over to the Nexus One, it was a no-brainer that it’s HTC branded twin, the HTC Desire, would get it too. The two devices are identical in specs and performance, with only a few minor differences in appearance, namely the Nexus One trackball being replaced with an optical trackpad on the Desire, and dedicated hardware buttons for Home, search and menu, and yes, the fact that the Nexus One was a stock Google device running pure Android, vs the Desire which came with HTC Sense.

MIUI, as many of you already know, is one of the favorite UIs/ROMs in the world of Android ROMs. It features a unique, and heavily themed interface, that does away with the traditional Android app  drawer and functions more like iOS, wherein you slide through homescreens to access apps. It also includes additional functionality not found in stock Android, including toggles on the notification pull-down, unique music app, gallery, and camera apps, and a modified phone dialer that displays matching contacts as a user enters a number. While some users find MIUI too similar looking to iOS, and hence prefer not to use it, there is no denying the slick, elegant, classy UI which you can further customize through hundreds of themes accessible from within the ROM, and the fact that it makes your device stand out from the crowd.

Before we move to read about how we can install this on the HTC Desire, you should know that while it is a working MIUI v4 port, it is still a beta, and not an official MIUI release yet. There may be some issues at the moment, however, these are being worked upon by the MIUI AU team, who has brought this ROM to us. It has been posted on XDA by XDA member lenny_kano . But like on the Nexus One, its a work-in-progress ROM, and it can only get better from here on 🙂 Have a look at some of the key features of the ROM in its current state, quoted from the development thread:

Enhancements

  • 4-Way Reboot MOD (thanks to roenano)
  • Spare Parts MOD (including nowhere near as much as previously, for now)
  • Mms user-agent and profile modified for better multimedia messaging

System Mods

  • Using ICS 4.0.3 CM9, b0.2.5 as a base (thanks to dk_zero-cool)
  • Camera partially working (a bit unstable, panorama force closes) (thanks to rapmv78)
  • Hardware Acceleration hack (thanks to rapmv78, rmcc)
  • RAM Optimisation script (thanks to Juwe11)
  • Security modified so that superuser and permissions management works properly
  • Custom hosts file for blocking ad servers
  • CM7 APN’s for better network connectivity
  • LED & Flashlight permissions reverted for compatibility with more apps
  • Custom installer script (See here for an explanation)
  • Customisable A2SD script (options in “Control” > A2SD Settings). Note that your phone will reboot TWICE automatically after you change your settings, in order to fix permissions and avoid issues.
  • Better GPS settings for Australian users.
  • OTA updates (Thanks to XJ & MIUI.us)
  • Automatically adjusts installation for any HBOOT (All HBOOT other than Stock, Sense, or Data++ cannot perform data wipe without reflashing rom due to system partition size limitations)
  • Modified ramdisk to support native USB mounting as well as other small fixes
  • Modified framework to support USB mounting, network connection, signal display, and various other minor fixes
  • Torch from gingerbread build included
  • FM Radio included but currently not functioning, will force close if you try
  • Included Trackpad2Wake (thanks to samuaz)

Applications

  • AppWidgetPicker for non-MIUI launchers (thanks to Boombuler)
  • Calendar Sync fixed
  • Gmail with 3rd party app notification support
  • QQPlayer 1.2.233 MOD (thanks to QQ)

NOT WORKING

  • Camera can be unstable, and choosing panorama will force close
  • FM Radio not functioning
  • Probably more

REQUIREMENTS

  • Will install on any HBOOT, provided you have an sd-ext partition set up as the second partition on your card. Only stock HBOOT can function without it.
  • Only stock HBOOT, Data++ and Sense can perform data wipe without rom reinstallation, due to system files needing to be moved for other HBOOT’s.
