Install MIUI 1.6.17 on the Xperia X10: Android 2.3.4 ROM Guide

The Android 2.3.4 MIUI 1.6.17 ROM for the Sony Ericsson Xperia X10 is an old, unofficial community port. It requires the exact supported X10 variant, root access, working xRecovery, and a ROM ZIP from a source you can trust. The original download pointed to Hotfile; I could not verify a surviving download or checksum. If you cannot confirm your archive matches the developer’s release, do not flash it.

Compatibility and known limitations

Sony lists the X10’s official software path as Android 1.6, 2.1, and 2.3. Android 2.3.4 here is custom software. MIUI 1.6.17 dates to June 2011, and a surviving release archive does not list the X10 among supported devices, so this build was an unofficial port and is no longer maintained. See Sony’s Xperia Android version list, the MIUI 1.6.17 release archive, and the historical XDA thread cited by the original guide. The XDA thread and its files may be unavailable.

The original post reported working calls, SMS/MMS, mobile data, audio, video, themes, sync, browser, music, gallery, GPS, and SD-card storage. It also said the camera and camcorder were broken; Camera Illusion was mentioned as a still-camera workaround. These are unverified 2011 notes, not guarantees. Expect missing features and instability.

Before you begin

• Check that the maintainer’s notes explicitly support your exact X10 model variant and list any required base firmware or kernel. Never use this ZIP on an X10 mini or mini pro.
• Have root access and a working xRecovery already installed. This guide does not cover rooting or installing recovery; the legacy tools must match your handset and firmware.
• Back up photos, contacts, and other personal files to a computer. Charge the battery and confirm xRecovery can read the microSD card.
• Use only a ROM archive with verifiable provenance. The old Hotfile URL is not a current download source. A Nandroid backup does not replace a separate copy of personal files.

A factory reset erases installed apps and phone data. Stop if the model, package, prerequisites, or backup is uncertain; a mismatched image can prevent the phone from booting.

Install MIUI 1.6.17 with xRecovery

1. Verify the package. Read the preserved developer instructions for the exact model, base firmware, and any required files. Keep the ROM as a ZIP; do not extract it.
2. Prepare the phone. Copy personal files elsewhere, charge the battery, and confirm xRecovery opens before wiping anything. The microSD slot is under the rear cover.

   

3. Copy the ZIP. Put the unchanged ROM file in the top level of the microSD card so recovery can find it. Eject the card safely, then reinsert it if you used a reader.

   

4. Check the copy. Confirm the ZIP appears on the card and the transfer completed. Compare a published checksum if one exists; without one, the filename alone cannot prove the archive is intact.

   

5. Open xRecovery. Power the phone off and turn it on. As the white Sony Ericsson startup screen appears, tap the physical Back key several times, as the original guide describes. If recovery does not open, stop and fix that first.

   

6. Make a Nandroid backup. Choose the backup option in xRecovery and wait for a success message. If possible, copy the backup folder from the SD card to a computer before continuing.

   

7. Wipe and install. Select Wipe data/factory reset, wipe cache and Dalvik cache if offered, then choose the install-from-SD-card option and select the exact MIUI ZIP. Menu wording varies; stop if your screen does not match the developer instructions. Do not interrupt the process.

   

8. Reboot and check. Use recovery’s reboot option after installation reports success, then allow the first startup time to complete. If the phone loops at the logo, return to the same recovery and restore your Nandroid backup; do not flash random files.

   

If something goes wrong

If xRecovery cannot see the ZIP, power down and check that the card is seated and the file is at its top level. If installation fails, record the error and consult the historical developer thread before trying again. If the phone will not boot, restore the backup rather than layering another ROM over it. With discontinued software and tools, there may be no supported repair if the correct package, recovery, or backup is missing.

This is a historical procedure for enthusiasts who already have the correct archive and a working recovery, not a supported Sony upgrade path or a verified download page.
