Is there a way I can get an app that comes preinstalled in a .ftf file by extracting the .sin file (or .tgz) into its components so I can get an apk. I suppose it's kind of an image?

Check the contents of the zip file, if it contains a .ftf file inside it you have to extract and use flashtool to flash it.
If it contains an updater-script then its probably a recovery flashable file, which means it won't work using flash tool.
If you rename and try, you most probably will get an error from the flashtool.
But i doubt its possible to brick your phone that way though
it contains .sin files and meta-inf folder

Most likely you should be able to. But can you quote the source and name of the file maybe?
Can I just extract them .img files regularily, or do I need a special archiver like 7zip for Windows?
I downloaded the D6603_23.0.A.2.93_Generic_20GLOBAL for the Sony xperia z3 from xperiafirmware.com and rather than the file being .FTF it is like this, Anybody know how to fix this or what I've done wrong, Thankyou.

FTF files are basically just zip files.
The folder it came in is a compressed folder. It seems you have extracted the contents from it. Make sure you have not hidden known file extensions in the windows options.
If not, just rename the folder to end in .FTF and it will be fine.
Yup, rename the entire folder to .FTF and It will flash just fine.

Thankyou! I've renamed the file and placed it into the flashtool firmware folder but when press the flash device button it doesn't show up, Not sure what to do from here.

Are you sure it was a file and not a folder you renamed....
When you download the file do not open it, just move it to the firmware folder

When I try to download it through Xperifirm I get the same problem but it doesn't come as an FTF file. It needs to be to work with PRFCreator.
Hello everyone,
I am tying to make a "light" official rom of the Z3 by removing some *.apk of an *.ftf file.
I have extracted all the folders from the *.ftf (ftf - system.sin - system.ext4 - files...) and removed all the apk I don't want, but I don't know how to make a new "system.sin" from all the files I have extracted. I looked from the internet, but I am a little noob.
Can someone help me to build a new *.ftf file to flash it with Flashtool ? :crying:

As far as i known you can't edit .sin / .ftf files as they are signed using sony private key that no one has...
Technical info here:
https://gist.github.com/dosomder/8ed79b26a5e063efa5ef
"And that is the reason why we can not create custom firmwares for Xperia. If you still don't understand, RSA is an asymmetric function.
This means it's using a private key to create the signature and a public key to read it. So even if we find the public key
(which is somewhere on the device), we can never find or guess the private key. Therefore we can not create a valid signature."
But you can create a .zip firmware to be flashed via recovery
I used Flashtool-sin editor on "system.sin" that give me "system. ext4".
With ext2explore I opened " system.ext4" and extracts all files and folders (app, privateapp, etc, build.prop...).
From folders "app" and "privateapp", I removed the *.apk I don't want, but I don't know if I can build a new " system.sin".
There is really no way to reverse ? Make a "system. ext4" from the folders I modified, and convert it in "system.sin" ?
If we can do something in a way, can't we do it on "reverse way" ?

It cannot be done. 100% impossible.
If you want to make your own rom Google [NUT]'s method to create your own rom.
There is also a tool to create your own prerooted flashable zip, but if course, all of this requires root
Thanks a lot for all your answers...
I won't try to make it in zip...
Can anyone give me tips on how to convert .ftf file to a .sin file so as to flash using fastboot?
