A2-DB3150 Flashing

[andyd]

immun0 - i just successfully debranded a W760a *and* have it updated to the latest firmware with SEUS. In addition, I have also successfully rebranded it to what it was before...

I just got a 760a myself. Do I need custom files, or just the main and FS? And which files did you use? You just did it, so I assume you used the latest.

Thanks for any detailed instructions you may give, i am a newb at this stuff. I have used Davinci before on different SE phones, but never A2 so far.

Hi xyn19. Thank you so much for reply. I've spent many hours already trying to debrand without success. I hope that you can help me. Can you tell me what MAIN and FS did you use? I've made a subscription so I should be able to access the download section soon. Are you in USA too? I'm in California and don't know if region matters with file selection. Did you change the CDA according to the instructions of this post? I tried to drag and drop my customized xml to the tpa/preset/custom but it won't stick.... Any help would be great. Thanks.

Hey I know what you're going through, can be frustrating. My W760a is also a US version. In my experiment, I used customized Hong Kong (1207-7195), because I wanted to see how it supports the various Chinese languages (it turned out surprisingly well, perfect in fact, another thread..). Depending on what languages you like, if it is just for the Americas, try the customized latin america(1208-4014)/southern cone(1207-5533) CDAs, it has cf,en,pb,xl languages. You can see the other CDAs from Top Sony Forums

Here's an easier way (use a2uploader to write customize_upgrade.xml only, and use SEUS to flash), follow exactly, let me know if there's a problem:):
1) get and install a2uploader and flash driver A2-DB3150 Flashing - Top Sony Forums, get and install SEUS from Sony Ericsson - Support - Software - W760a - Update Service
2) create following customize_upgrade.xml on your PC with correct CDA

<?xml version="1.0" encoding="utf-8"?>
<customization>
  <info>
    <cda-number>0000-0000</cda-number>
  </info>
</customization>

3) Connect USB cable to PC (not phone)
4) Fully charge battery. Pull phone battery out, wait for 3+ seconds, put it back in
5) Start a2uploader, click on FileSystem Tool
6) Hold down "5" key on phone, then plug in USB cable
7) Wait for a2uploader to display some info about your phone in the text box to the left, then release "5" key.
8) In a2uploader, double click on tpa, preset, custom, to go to that folder
9) Drag and drop your customize_upgrade.xml to the /tpa/preset/custom/ folder, you should see that file in there if copied correctly
10) Click on FS Shutdown, or something like that
11) Disconnect USB from phone (not necessarily from PC)
12) Take phone battery out, wait for 3+ seconds, then put it back in
13) Turn ON phone, wait until you reach phone's main screen. Turn it OFF.
14) Start SEUS and follow the directions from there, long process, may take 20 min to a few hours, depending on your download speed. (require internet connection of course)
15) Now you have the latest firmware from SE! and you can continue to use SEUS in the future!
16) Enter settings for your service provider, and some necessary tweaks to make other things work (e.g. streaming ATT's video from http://home)

Good luck. Post back questions and results, cheers. ;)

Hi, xyn 19.
Every info is very new to me. So if you'd help me to debrand my w760a, I would greatly appreciate it.

First of all, I am using AT&T branded phone right now, and I would like to debrand to Taiwan CDA (1207-3657). I don't know the difference between Hong Kong(1207-7195) which you debranded and this Taiwan(1207-3657). The bottom line is that I want to read Japanese. Some people mentioned on the web that if the phone has Chinese font, then that phone is good for reading Japanese too:).

Anyway, according to your post #76, all I have to download and install are A2uploader, flashdriver, and SEUS. Then make a "customize_upgrade.xml" by copy and past on the #76 and changing "<cda-number>1207-3657</cda-number>".
Then, follow the instraction you provided.

Is my understanding correct?
or, do I need to purchase "custompack w760i 1207-3657 R4A customized Taiwan" from Top Sony Forums? In this case, I have no idea how I should use this files.

Thank you very much

How to get access to Download Area? - Top Sony Forums

Open this:

<?xml version="1.0" encoding="utf-8"?>
<customization>
  <info>
    <cda-number>1201-0095</cda-number>
  </info>
</customization>

in notepad.
Save it as "customize_upgrade.xml". Upload it to TPA/preset/custom. Update with SEUS. You should have the latest "generic america" firmware.

I used this as my custom xml.

So I used this, uploaded it as you said, and then SUSE did the rest.

what i open a2uploader.rar put a2uploader.exe in my C:\a2uploader
Symantec-Antivirus sais is the virus???

[xyn19]

I have Enterprise Mcafee installed on this PC with latest definition files, and it's not reported as a virus. From what I have read, this is a false detection, you need to exclude it from Norton. Have you the latest virus definition files?

Please allow a very silly question... do I add the files before connecting the phone (holding c button) or after? I'm a newbie so pls don't start laughing at me :p

Hm...I add the files...I press flash and then connect the phone holding c button...correct?

Also...you say...
6. After flashing shutdown phone, remove batery and insert it back.
Should it be ON during flashing??
