Sony Ericsson has updated its SE Update Service (SEUS) software over the last week to version 2.10.7.15. There’s no way of trying to run the older version as SEUS will automatically update it once started. One of the main changes appears to be a fix that SE has implemented to stop people debranding their handsets.


The guide below shows you how to unbrand the handset.

new guide on debranding your handset ( Step -* 8*)


1) Download one of the following files depending on which region you are in. Each download contains two files (a +100MB one and a +10MB one).


Download link on POST #3

Please note:
Flashing your Xperia X10i to X10a (and vice versa) will result in SEUS not being able to update your phone for future updates.



2) Delete contents of db folder (C: –> Program Files –> Sony Ericsson –> Update Service –> db).

3) Run the Sony Ericsson Update Service (SEUS) to update your Xperia X10

4) Go to C: –> Program Files –> Sony Ericsson –> Update Service –> db –> 13740270 –> blob_fs.

5) Sort files by date in descending order (latest date at top). The two files at the top will be +100MB and one around 15MB.

6) Backup these two original files into a different directory. This is an optional step but means you can revert back to the branded firmware if needed.

7) Now find the two files that you downloaded in Step 1. Rename the largest file with the same name as the largest one in blob_fs. Do the same with the second.

8 ) IMPORTANT: Please read this step fully before executing it.

Run the Sony Ericsson Update Service (SEUS) again. It should say that you already have the latest update, click on the reinstall button anyway. The program will then start to re-download the same files. The trick here is to replace the files that are being re-downloaded with your new files from Step 7.

Open up Windows Explorer and navigate to the blob_fs folder. SEUS will first re-download the smaller (+10MB) file. Constantly monitor this folder to find out when the smaller (+10MB) file has been fully downloaded again. Once it has, immediately move your smaller file from Step 7 into the blob_fs folder and overwrite the file.

Now for the larger file. Keep an eye on the download progress bar in SEUS. Once the download is very near to completion you will need to copy the larger (+100MB) file from Step 7 into the blob_fs folder and overwrite the file. Time the file transfer for when there is literally around 1/2MB left to be downloaded.

If successful, the installation will carry on as normal. If not, try again. Don’t worry you will not brick your phone if it doesn’t work. It will simply tell you that the installation failed.

9) Voila! Your Xperia X10 is unbranded.

Hay All.,

I just downgread my x10i to previous version i.e. R2BA20 to R1FA016.
And then use the update service absolutely under Setting to update my set to R2BA023.

Really very happy now to see the performing improvement.

80% Complete with the new firmware (after downgrading)

The SEUS update gave me quite the sacre..thought i will be forever stuck with the O2 branded firmware :p

Aparently ota updates around 40mb n seus updates around 140mb.. people are claiming the seus update have improved their x10s better than the actual ota updates through personal experiences..
