I have written the following information to compliment the instructions Achotjan has kindly provided above for us.

Pre-Upgrade tasks

Charge your phone up to at least 50% battery capacity.

Your XPERIA X10i will need an unlocked bootloader.

Your XPERIA X10i will need a supported Micro SD card with at least 500MB of free space.

Your XPERIA X10i should have an active SIM card, however you can use an inactive SIM which negates the first mobile data network connection costs when the first time setup is preformed.

Install flashtool on your PC.

Any of the latest versions of flashtool will do, provided you already have USB drivers installed.

Older versions of flashtool do have better support for legacy services on the XPERIA X10i such as xRecovery(not required any more) and USB drivers and etc.

If you do get flashtool v8.0.0 please remember to also install flashtool 8.0-8.6 upgrade bespoke to this version.

Download Somc Debrand Engine ROM to your PC and then copy the .zip file to your XPERIA X10i mobile phone.

This will require at least 300MB of free space on your TF/SD Mirco card of your XPERIA X10i.

The ROM install file you download to your XPERIA X10i should be a .zip file format and approx 300MB in size.

You can also use a Micro SD card reader attached to your PC and just copy the ROM.zip file to the card and then insert the card into your XPERIA X10i

Download Somc Debrand Engine Kernel to your PC.

If the Kernel download is in a .zip format, extract the included file which should be of .ftf format and approx 5-6MB in size.

Move the .ftf file to the /firmware folder on your PC in the location you have installed Flashtool.

Have on hand a USB/Micro USB cable to connect your XPERIA X10i to your PC.

If you have an active XPERIA X10i, then connect the phone with your USB cable to your PC with Flashtool application running.

If the USB drivers are installed and your XPERIA X10i has root access you should see something like the follow:

I already have SDE-v1 ROM installed in this example.

The output you see should reflect the current ROM you have installed on your XPERIA X10i

You are now ready to install Somc Debrand Engine JB 4.1.2

Installation Procedure.

Flashing the Kernel.

Power down your phone and remove the battery. Replace the battery after 30secs.

By removing and replacing the battery you are removing any chance of the phone retaining dynamic chipset instructions.

On the PC start Flashtool and enter flashmode.

Select the Somc Debrand Engine Kernel you wish to install and 'click' on the Flashtool application Flash button.

A panel on your PC should now be displayed requesting you to connect the USB cable from your PC to your XPERIA X10i while you hold down the back button on the XPERIA X10i.

The back button is the button located on the right of the phone when looking at the face of the phone.

Important

Please check the following in your Flashtool logging output

06/023/2014 13:23:14 - INFO - Loader : S1_Loader_Root_f851 - Version : r4A024 / Bootloader status : ROOTED

If your logging output does NOT show Version : r4A024 but has Version : R4A024 instead, your bootloader is still locked.

Version : r4A024 MUST have a lowercase 'r' in r4A024

After you have completed the flash of the Kernel, remove the battery and wait for at least 30sec before replacing it.

You can also press the power on/off button while the battery is out of the phone.

This may help drain any residual power in the chipset/circuits before the battery is placed back in the phone.

Installing the ROM.

With your SIM card, Micro SD card(with ROM.zip included) inserted, power on your XPERIA X10i.

The XPERIA X10i should vibrate when the power button is pressed.

You should see a Semc Debrand Engine logo on the screen.

After a period of time, approx 1 - 2 minutes you should see the blue LED flash and the phone should vibrate.

When the blue LED flashes press the volume up button to enter CWM recovery.

In CWM recovery format/clear the following partitions and clear the dalvik-cache. (best practice)

Select "mounts and storage" from the main menu

- format /cache

- format /data

- format /system

Select "advance" from the main menu

- wipe dalvik cache

Now "install zip from sdcard" locating the ROM.zip you wish to install.

Thank you for your trust

Install from sdcard complete.

Boot System

In CWM recovery return to the main menu and select:

- reboot system now

The Semc Debrand Engine logo will be seen.

After the blue LED light has flashed, the Semc Debrand Engine logo will remain on the screen for a few more minutes.

You should then see the XPERIA logo for a couple of seconds and then the swirling colours stream across the screen.

The first boot could take several minutes as system files are prepared and cached.

Don't be surprised if the system is still booting after 3-5 minutes.

On first boot, answer the initialization wizard setup questions.

Enjoy SOMC Debrand Engine JB 4.1.2 on your Sony Ericsson XPERIA X10i

Still have problems.

Your bootloader is probably locked.

You didn't format /cache, /data, /system and clear dalvik cache.

When you don't clear/format your previous install, the XPERIA X10i will go into a Android OS boot loop were you will see the boot process continually returning to the XPERIA logo and starting again.

Did you forget to remove the battery at key points during the install?

If you are still unable to install a new Kernel and get to CWM recovery, reinstall Sony GB 2.3.3 via SEUS(Sony Update Service)

● Install a fresh copy of Sony Ericsson's GB 2.3.3 using a Sony update service

● DO NOT power on the new version of GB 2.3.3 you have just installed

● Go back to Flashtool and re-install/flash the original Kernel you wish to use which has CWM recovery included.

● Power on the phone and this time your new Kernel should be able to invoke CWM recovery.

Did you following the above instructions???
