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...

I can't copy or move files stored in device ROM.
I've tried with Resco Explorer and Total Commander, but without success.
I didn't understand if there's a registry hack that allows these operations.
I've notice (or so it seemed to me) that I was able to substitute/copy/move some files having the ROM attribute, but many others not (eg: I've tried to copy the nleddrvr_sec.dll, obviously without success, otherwise I'd post this here!).
Surfing in many forums, I read many others asking for the same thing, unfortunately I haven't seen answers to their question about this.
Hope someone explains to me how to do or why is impossible to do.
Mersì bo q.

You can not copy / move / delete files in ROM. Thats the point of "Read Only Memory"
These files are not stored as individual files but are in fact packed in a special way as part of the device image which can only be written (flashed) by special tools.
If you want to extract OS files you need to use a ROM dump tool.
I suggest you look in the WiKi.
What you can do is overwrite one or more "ROM files". What will happen in reality is that a copy of the file with the same name will be placed in storage memory and the system will go there. If you hard reset your device or rename the file it will go back to the original file.

As you said here and here (Changing Files in Windows Dir )
it's impossible to move/copy ROM files, just overwrite 'em.
Doing so the system looking for these overwritten copies.
So now the question are:
- there's a registry entry that points to this substitute ROM files?
- to modify an existent file resident in ROM I MUST dump my ROM or another one same or similar?
Mersì bo q, anyway.

That would be perfect

Hello! Before posting, i search this forum but not found nothing understandable. I wont to modify .ftf file of sony xperia e single sim, edit some apps and repack in fleshable ftf again, but i have some problems. Ok i'm doo next:
1. Extract flashtool via winrar.
2. Copy system.sin to flashtool directory and extract with sin editor, and get 2 files system.ext4 and system.partinfo, but with flashtool only possible to extract yaffs2 files. 3. Here is big problem, i tryed menny softwares for opening ext4 images in windows, but only ext2 exploer can modify this files, but totaly inaccesible with screen readers like as jaws.
4. I found some tutoryals for mounting in linux but i can not understand linux commands as well, for example did i must know exactly syze of system partition to mount ext4 image, maby exist some gui program for linux from wich can mount end edit ext4 images?
Finally, does possible making flashable img or ftf file for sonny phones for custom roms? For example, easyer to me is flashing custom roms via fastboot, because in some situations for cm recovery i need sited assistance.
Thanks, and best regards.

I have looked around to repack an extacted system.sin but never found how to do it. To dump the ext4 img just use ext2 explorer after it has finished extracting & loading click save in the toolbar and choose the folder where you want to save it.

There's no tutorial on how to build one or a tool. Not for windows anyway.
I use Bluestacks 0.9.11.4119 . I Install android applications and games, from root folder (i.e. device/android/data/data) i copy all the folders to windows directory (i.e. publicfolder/pictures), now many of the apps or games have two type of similar files and i need to see what's inside of the files,
1st.- .so files and database files
2nd.- some of the files have no extension so if i open it on notepad then it comes in Alphanumeric symbolic format,i think its encrypted so i am not able to see even i have tried many language decrypter but failed
3rd.- how to dissemble the apk file and how to modify it.
4th.- how to read XML file of android apps, when i open it on notepad or Microsoft XML it shows error.
I want to learn something so please help me with these issues, and thank you for previous help
To edit any apk is necessary Apktool. Look this guide and try edit:

In addition to apktool (thanks, @kaiodduarte), you're also going to need a good text editor (I use Notepad++), an archive manager (like 7zip or WinRAR), and the ZipSigner app for your device.

It will help you with actually being able to make edits to text files without screwing up all of the line endings and encoding.
Hi!
I'd like to know where the OTAs are stored in our M2. Anyone that hasn't done yet the update download, and that has Root permissions, can use this app to find where they're stored, and if possible, upload it and post a link to it.
Thank you!
Do you still needed the file, sir ?

Yep. It's for some research
I think, the app didn't work sir. After I wait 30 minutes, none of the files were copied to my storage. Then I try searching using manual method, I found one file, the file size is as large as my OTA update. The nama file is "update-package".
The file extension is not ".zip", in the folder recovery (internal storage). My estimate, the file extension .LZMA or .tar.LZMA or .zipx.
I've tried to extract and decompress in the PC (windows os) using some programs, but failed.
If you still need the file, I'll upload it now .

Okay, so this is what I got:
The update zip refuses to be flashed in UBL devices. FOTAkernel system is broken after you open the bootloader, which leads us with an unused partition (but that's other thing). The recovery logs just say: WARN: Status Rooted, ERR: Bootloader is unlocked.
I've tried to force it using AOSP Recovery commands
Code:
echo 'boot-recovery' > /cache/recovery/command
echo '--update_package=/sdcard/update.zip' >> /cache/recovery/command
reboot recovery
But just got a big nope.
So, now time to have a look at it. I tried to unpack it several times but no luck. The reason seems to be, very probably, because this is a LZMA compressed file (as 7-Zip reported) but with 2 additions at the end (which corrupts the entire read of it): An unencrypted/uncompressed XML which points out which is the software available right now in the phone (<source>), and which is the version that is going to be installed (<target>), plus, some a weird <generation> section. This is the XML
Code:
<?xml version='1.0' encoding='ISO-8859-1'?>
<metadata version="3.3">
<product>
<manufacturer>Sony</manufacturer>
<model>D2302</model>
<hwplatform>msm8226</hwplatform>
</product>
<update>
<generation>
<version>1.1.2</version>
<date>2015-12-28T12:10:19Z</date>
<rb_version>7.0.15.117</rb_version>
<rb_ua_version>7.0.15.117</rb_ua_version>
</generation>
<source>
<software>
<revision>18.6.A.0.175</revision>
</software>
<customization>
<variant>1281-0464</variant>
<revision>R2C</revision>
</customization>
</source>
<target>
<software>
<revision>18.6.A.0.182</revision>
</software>
<customization>
<variant>1281-0464</variant>
<revision>R2C</revision>
</customization>
</target>
</update>
</metadata>
And, right after that, I can perfectly see a SIN header, so I isolated it and, looks quite similar to the FOTAkernel.sin included in FTFs (330613072905Z010U S1_FOTA0 ‚"0), I personally guess it's a very, very small ELF binary, by the size of it.
So, the problem now comes to isolate the 3 parts, the LZMA file, the XML and the SIN, separetly. After that, I think we can probably have a look insde them.
How about linux os? Can we unpack or decompress that file on linux os, sir? Do you have tried?

I've tried many tools and combinations (ext4, .img, etc) and none of them worked... I'll think more about it.
