Debrand your Xperia X10 [Tutorial]

Posted: June 13, 2010 in Uncategorized

Those of you with carrier branded Sony Ericsson Xperia X10 handsets need to fret no more. Some of the clever folk over at esato have figured out how to unbrand the handset. Debranding enables you to get the latest updates quicker and hopefully speeds up the handset too.

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
Brazil Generic X10a Firmware (R1FB001)
North America Generic X10a Firmware (R1FA014)

X10i
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 top one in blob_fs. Do the same with the second. Move these downloaded files into the blob_fs folder, overwriting the original files.

8 ) Run the Sony Ericsson Update Service (SEUS) again.

9) Voila! Your Xperia X10 is unbranded.
