We have attached a quick tutorial and the necessary files to debrand your X10 below. The instructions will debrand your Xperia X10 handset to the generic firmware that you choose to download . Please note that although the process is straightforward, there is a risk that you may brick your handset when flashing the phone. The Xperia X10 Blog absolves itself from any responsibility should you decide to carry on and you break your handset. Please proceed with caution and at your own risk.
Tutorial on debranding your Xperia X10
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).
The firmware list is in date order (newest at top):
X10a
Latin America Generic X10a Firmware (R2BA026)
Brazil Generic X10a Firmware (R1FB001)
North America Generic X10a Firmware (R1FA014)
X10i
Nordic Generic X10i Firmware (R2BA026)
Nordic Generic X10i Firmware (R2BA023)
UK Generic X10i Firmware (R2BA020)
German Branded (O2) X10i Firmware (R2BA020)
Swedish Branded (Telenor) X10i Firmware (R2BA020)
Nordic Generic X10i Firmware (R1FB001)
Nordic Generic X10i Firmware (R1FA016)
Iberia Generic X10i Firmware (R1FA016)
UK Generic X10i Firmware (R1FA016)
Hong Kong Generic X10i Firmware (R1FA014)
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.

Troubleshooting Tips
Phone bricked/Yellow exclamation mark: If when debranding you end up with a yellow exclamation mark on restart don’t panic. To get your phone working again, try either of the following two methods:
- Delete the ‘13740270’ folder at the following location: C:\Program Files\Sony Ericsson\Update Service\db\13740270. Use SEUS to update your phone again. You should be given two options, choose the bottom option “Restore Factory Settings”. OR
- Use this Flash Tool to help unbrick your Xperia X10i. For instructions read the ‘HowTo.txt’ from the flash tool. [Thanks to jerpelea from xda-developers for this flash utility].
APN Settings: Go to Settings –> Wireless Controls –> Mobile Networks –> Auto Internet settings, to automatically detect your settings. If this is disabled (for example if you are downloading branded firmware) then click on this Sony Ericsson page which will automatically send you the necessary settings.
