Downgrade Sony Ericsson Xperia Ray from ICS to Gingerbread (Unlock Bootloader + Root + CWM)

If you want to have the best experience on your Xperia Ray, I would ask you to downgrade to Gingerbread (Android 2.3) from ICS (Ice Cream Sandwich). I have tested ICS (Ice Cream Sandwich) on my device, and never found the desired experience. Select Gingerbread, it’s fast and that’s the sole reason for me sticking to Gingerbread over the ICS.

I can just share the tutorial for how to downgrade to latest Gigerbread firmware, but leaving you without root and CWM will be no fun. Below is the tutorial which will have your ray running Android 2.3.4 – Build 4.0.2.A.0.62 with bootloader unlocked + root + CWM installed.

Requirements;

1. Download Flash tool from here (go to installation tab).
2. Download Android 2.3.4 – Build 4.0.2.A.0.42 from here. 
3. Download Android 2.3.4 – Build 4.0.2.A.0.62 from here. 

Procedure to Downgrade Sony Xperia Ray from ICS to Gingerbread;

1. Install Flashtool. The default installation location is (C:\Flashtool)
2. Also install the driver package found under ‘C:\Flashtool\drivers’ if you don’t have already (select pro-ray adb drivers, flash mode drivers and fastboot drivers).
3. Unzip the file downloaded at 2nd requirement and place it under ‘C:\Flashtool\firmwares’.
4. Open Flashtool, click Flash sign and select ‘Flashmode’ (see the screenshot above).
5. Select ST18i and click OK.
6. Follow on-screen instruction (unplug it from USB, power off, press volume- and not the back button, plug the USB cable) and you will have Gingerbread on the phone.

Root and Unlock Bootloader (Gingerbread only) of Sony Xperia Ray;

1. Download the zip file from here.
2. Connect Phone to USB (Make sure in settings, you have checked ‘Install unknown resources + USB debugging + Screen awake + activate Mass storage mode).
3. Execute “RUNME.bat” inside the folder you extracted at no 1.
4. Follow the instruction that is being displayed.
5. The phone will be rebooted and it’s bootloader unlocked and rooted.

Install Busybox and CWM Recovery on Sony Ericsson Xperia Ray;

1. Install BusyBox Free from ST Ericsson from Google Play. Open it on your device and let it install few files.
2. Download the SE Tweak Installer from here (XDA forum page).
3. Connect Your Phone to USB
4. Run the SE Tweak Installer, select the device type to the Ray one (Make sure you have checked ‘Install unknown resources + USB debugging + Screen awake + activate Mass storage mode)
5. Press Install and follow the process.
6. Check Auto Reboot if you want to test right away (while reboot, press volume+ key multiple times.

If you have followed the steps carefully, it’s done. The next part is installing the latest version of Gingerbread but we leave few things such as kernel.
