Pre-Installation Requirements/Tips

  1. A Nexus S 4G with Clockworkmod recovery installed
  2. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD card, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.

How to Install MIUI on Nexus S 4G

  1. Download the latest version of the MIUI ROM from the original development page.

  3. Now, transfer the files you downloaded in step 1 and 2 to your phone.

  5. Now, perform a full wipe:
    1. Select “wipe data/factory reset”, then select “Yes” on next screen to confirm data wipe (will NOT wipe your SD card). Wait for wipe to complete.
    2. Select “advanced”, then select “format system”, then select “Yes” to confirm.
    3. Select “format boot”, then select “Yes” to confirm. Then, select “go back” to go back to the main recovery menu.
  6. Now scroll to the option “Install zip from sdcard” and select it. Then select “choose zip from sdcard”. Scroll to the ROM file you downloaded in step 1 and select it. The ROM will now start installing.
  7. After the ROM finishes installing, select “go back” then select “reboot system now” to reboot the phone.
  8. Once the phone boots, you will get lots of ‘Force Close’ errors. Son’t worry and simply power off the phone.
  9. Boot into recovery again like you did in step 4. Select “Install zip from sdcard”, then “choose zip from sdcard”. Scroll to the file you downloaded in step 2 and select it.
