Your phone will install Android OS in 3-5 minutes and then you can enjoy your flashed phone But sometimes you can't find specific firmware with .ftf extension, but you can find .sin_file_set files. Can we use them? Yes! Using Flashtool we can convert .sin_file_set files to .ftf files and flash them.
Create your own bundle tutorial:
1. Download from internet .sin_file_set files for your phone. You need both appsw and fsp files. You can also flash elabel and cdf files, but those are not required.
2. Create new folder on your desktop (or any other place on your hard disk).
3. Open your appsw .sin_file_set file using WinRAR and copy to your new folder all .sin files:
