Updating Your Sony Ericsson Xperia Ray with CyanogenMod 7.1 Gingerbread 2.3.7 Firmware

December 15, 2011

Sony Ericsson users can now rejoice. The CyanogenMod developer team has released CyanogenMod version 7.1 and it is now available for installation on the Sony Ericsson Xperia Ray.  CyanogenMod 7.1 includes the latest version of Android 2.3.7 Gingerbread firmware, as well as a whole slew of other functionalities.

As always, it is necessary to follow the instructions accurately to prevent the unfortunate event of bricking your phone.

Applying this update requires you to root your phone, which consequently voids your warranty. If your phone has already been rooted, you may skip the step for unlocking the bootloader.

Pre-Firmware Update Instructions

  • If you are using any other custom ROM, then you need to disabled it.
  • It’s highly important to back up the data on your phone in the event that whatever information on the phone may be lost or corrupted.
    • Text Messages — Use the SMS Backup and Restore app
    • Phone Contacts — Sync with Gmail application
    • Call Log — Use the Call Logs Backup and Restore app
    • Pictures, music, videos, files, etc. — Copy to the internal/external SD card
    • Internet & MMS Settings — Backup all the settings from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names”
  • All firewall tools, antivirus programs and PC Suites should be completely closed on your desktop so that these tools do not interrupt the process of the firmware update.
  • Ensure that USB Debugging has been enabled on your phone through the path “Settings > Applications > Development > USB Debugging”.
  • Ensure that your phone has a charge of at least 60% so that it doesn’t shut off in the middle of the updating process.
