How to debrand Sony Ericsson Z750a from AT&T to SE

How to debrand Sony Ericsson Z750a from AT&T to SE

If you have a sony ericsson Z750a from AT&T the probably you are not utilizing its great feature, like it has inbuilt GPS, which AT&T has disable, i don't know why AT&T has disable it as this is the main feature of this cell phone, and even i am surprised to see that Sony Ericsson also does not promote this feature. They not published it as a feature, they have only mentioned this feature of phone in there manual only, and that too in other feature section.....

Any way if you have the Sony Ericsson Z750a from AT&T, i will guide you the step how to debrand.
I have successfully done this fro my phone and got the GPS working great.
Please follows the step (on your own risk)
1. Download and install A2 Up loader and the USB flash drivers that come with it. Do a google search and you will find this.
2. if you have antivirus installed on you machine then they detect this as threat, this is because this software read the boot sector and other file of your cell phone. so temporarily disable the antivirus.
3. Download and install Sony Ericsson Update Service.
4. Use a text editor to create a file named customize_upgrade.xml
All it needs to contain is below – the generic CDA allows SEUS to recognize the phone and will upgrade. I used the 1206-7735 “Custom USA” CDA.



You can use A2_CDA_File_Generator to create this file, a good and recommended option to avoid any thing wrong. This tool is also available on net free.
5. Power off phone, remove battery and then replace it. Leave the phone powered off.
6. Connect the USB cable to the computer, but not the phone.
7. Execute A2 Uploader and select the File System tool
8. Hold down “C” on your phone and plug it into the computer (A2 uploader prompts you to do this).
After A2 Uploader accesses the file system, you can release “C”. Then browse to tpa\preset\custom directory and copy your new xml file there (drag and drop).

10. Quit the file system, then stop and exit A2 uploader and remove phone from computer cable.
Power on the phone to load the new CDA, then power off again.

11. Start up SEUS and browse for the Z750 phone and follow the instructions. You do not need to remove the battery again, but do need to hold down “C” before plugging phone into computer again. Release “C” when prompted and SEUS will do the rest.
Loading the new software takes about 20 minutes.

12. You have the original SE software with GPS activated in your phone.
13. To use GPS go to Location Service (Which was not present in AT&T version). and use Status Info to find you current position (Longitude, latitude) and use inbuilt google map to navigate.

Please not that this will void the warranty of you phone with AT&T. So do on you own risk though the success rate of debrading in near to 99%. i never fail.
Just be sure that you phone is 100% charged before following the debranding procedure.

By above mention step you can customize you phone according to you region/country with local language and capability.

Happy Programming.............

New Feature in ASP.NET 3.5

Microsoft released ASP.NET 3.5 on November 19, 2007. Along with it, was released Visual Studio 2008. This evolution from ASP.NET 2.0 to ASP.NET 3.5 is quiet gradual. ASP.NET 3.5 uses the same engine as that of ASP.NET 2.0, with some extra features added on top of it. In this article, we will explore the new features added to ASP.NET 3.5. This article assumes that you have been working on ASP.NET 2.0.

ASP.NET AJAX
In ASP.NET 2.0, ASP.NET AJAX was used as an extension to it. You had to download the extensions and install it. However in ASP.NET 3.5, ASP.NET AJAX is integrated into the .NET Framework, thereby making the process of building cool user interfaces easier and intuitive.
The integration between webparts and the update panel is much smoother. Another noticeable feature is that you can now add ASP.NET AJAX Control Extenders to the toolbox in VS2008. Even though this is an IDE specific feature, however I feel it deserves a mention over here for developers, who had to add extenders using source view earlier. It is also worth noting that Windows Communication Foundation (WCF) now supports JSON along with other standard protocols like SOAP, RSS and POX.


New Controls
The ListView and DataPager are new controls added along with a new datasource control called the LinqDataSource.
ListView
The ListView control is quiet flexible and contains features of the Gridview, Datagrid, Repeater and similar list controls available in ASP.NET 2.0. It provides the ability to insert, delete, page (using Data Pager), sort and edit data. However one feature of the ListView control that stands apart, is that it gives you a great amount of flexibility over the markup generated. So you have a complete control on how the data is to be displayed. You can now render your data without using the

tag. You also get a rich set of templates with the ListView control.
DataPager
DataPager provides paging support to the ListView control. The best advantage is that you need not have to keep it ‘tied’ with the control on which the paging is being done. You can keep it anywhere on the page.
DataPager gives you a consistent way of paging with the controls that support it. Currently only ListView supports it as it implements the IPageableItemContainer. However support is likely to be added to other List controls as well.


LINQ
LINQ (Language Integrated Query) adds native data querying capability to C# and VB.NET along with the compiler and Intellisense support. LINQ is a component of .NET 3.5. LINQ defines operators that allow you to code your query in a consistent manner over databases, objects and XML. The ASP.NET LinqDataSource control allows you to use LINQ to filter, order and group data before binding to the List controls.

ASP.NET Merge Tool
ASP.NET 3.5 includes a new merge tool (aspnet_merge.exe). This tool lets you combine and manage assemblies created by aspnet_compiler.exe. This tool was available earlier as an add-on.

New Assemblies
The new assemblies that would be of use to ASP.NET 3.5 developers are as follows:
· System.Core.dll - Includes the implementation for LINQ to Objects
· System.Data.Linq.dll - Includes the implementation for LINQ to SQL
· System.Xml.Linq.dll - Includes the implementation for LINQ to XML
· System.Data.DataSetExtensions.dll - Includes the implementation for LINQ to DataSet
· System.Web.Extensions.dll: Includes the implementation for ASP.NET AJAX (new enhancements added) and new web controls as explained earlier.

Important Points
1. ASP.NET 3.5 provides better support to IIS7. IIS7 and ASP.NET 3.5 modules and handlers support unified configuration.
2. You can have multiple versions of ASP.NET on the same machine.
3. For those who are wondering what happened to ASP.NET 3.0, well there isn’t anything called ASP.NET 3.0.
4. VS 2002 worked with ASP.NET 1.0, VS 2003 worked with ASP.NET 1.1, and VS 2005 worked with ASP.NET 2.0. However VS 2008 supports multi-targeting, i.e it works with ASP.NET 2.0, and ASP.NET 3.5.
