Hello guys....After going through a lot of threads, I have seen a lot of users experiencing the loader_unlocked.sin error in flashtool. So I have made this guys to help all those people.
The error is something like this :
Code:
C:\Flashtool\devices\SK17\loader_unlocked.sin (System can not find the file specified)
This error is generally caused due to a missing file in most of the directory known. So here are the steps of overcoming this error :
1. Go to the directory where you have installed flashtool, for e.g. C: Drive.
2. Now open flashtool folder and select the devices folder from it and open the folder.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
3. Now open the R800 device folder.
4. Then copy the file loader_unlocked.sin from the folder.
5. Now open your device folder, for example SK17, i.e., Xperia Mini Pro. The "i" or "a" version doesn't matter.
6. And finally paste the loader_unlocked.sin in your your device's folder and now run the flashtool and you will be most probably successful!

Thank you very much for that, my phone's now working again!
One thing I really need to know though, should I remove that loader-unlocked file if I flash anything in future? Or do I need to keep it in the folder (in my case the ST18 folder) for good?
