First of all I'd like to say that it's imperative that You do everything on that list, and in this exact order. Everything here is important (the file names, the backup and so on). I also take no responsibility for toasted phones, this unbrander-thing isn't designed by me.

Second thing: whatever people write, as for 16.11.2005 this thing here works, I myself unbranded my p910i yesterday, got the newest firmware and the phone works excellent. Because of some changes SE made, it works now only for the p910i (p900 can't be supported by this free method)

Read the WHOLE Tutorial before starting !!!

1. You have to have the seus (Sony Ericsson Update Service software) 1.18 installed and running ok, if there are problems with that, sort them out first. The software installs automatically the first time You try to update Your phone, if You don't have it yet, go and install now.
Installation instructions can be found on the official Sony Ericsson website

2. Make a full backup of Your phone and write down Your current CDA (CDA determines Your software/branding and may be useful if You want to go back to the branded version). You can read the CDA by clicking Edit -> System Information and clicking the right-arrow.

3. Download this file:

4. Go into Sony Ericsson Update Service directory (usually C:\Program Files\Sony Ericsson\Update Service)

5. Go into the hfclasses directory and rename the SEMCXUSB.dll file to SEMCXORG.dll

6. Now unpack the file You downloaded into the hfclasses dir (both files must be present and have exactly the names stated above). As this seems to be misunderstood sometimes here it is in another words: the original SEMCXUSB.dll is now SEMCXORG.dll, new SEMCXUSB.dll is the one You downloaded separately.

7. Go here and choose Your desired firmware (the one You want to upload). Firmwares labeled 162005/1-9 are all the same, they only come with different language packs, so You are free to choose. Language packs can be downloaded from the SE website so it doesn't matter in the long run, just changes the set You'll start with. I live in Poland and had the polish Orange firmware (CDA was 162006/77) and changed it to 162005/1 (Northern Europe) as I use the english language only.

8. After picking the firmware, create a file named unbrander.conf in the hfclasses directory. Watch out for the extension, some text editors add .txt to text file names.

9. Edit the file and paste the firmware version i.e. cda=162005/1 and then press enter. The file must be exactly 14 bytes long (that's why the enter is needed).

10. This is a good time to double-check everything is done properly and that You actually did everything (don't forget the backup).

11. This is the final phase: updating. Close all unnecessary apps, leaving just the browser (not necessarily IE, I accomplished it with Opera).

12. Go to the SE website, find Your phone (p910i Smile) and start the update procedure. When asked, select Automatic Mode.

13. Do as the website says (You'll be asked to power the phone off and put it in the cradle - this has to work properly too).

14. Now, if by any chance, You get the message "Sync Station busy, other application using it" or similar, press Ctrl+Shift+Esc and kill these processes: audedevicemgr.exe COMM~1.EXE MROUTE~2.EXE. The sync icon will disappear from tray, but fear not, everything will work fine.

15. Now SEUS will start, ask You to press enter a few times and then it's party time. First SEUS downloads all files then flashes the phone (the phone MUST BE FULLY CHARGED before starting, a power-down while flashing is a no-no). The download time depends on Your net connection (on my 512kbit/s it took ca. 10 minutes). The flashing itself takes ca. 45 minutes. Try not to use the pc while doing this, You never know what might happen. When the process finishes, Your phone boots and asks to choose language.

16. Go to the backup app and restore Your backup (You did that, right?).
