I am new into creating and editing custom roms. But now after creating one i have zip file as my output and i need to test this on my android emulator. I have read that you need a system.img file to work in an emulator. If then how do i obtain my .img file from a zip file?
I have have an idea about yaffs2 but does not have any idea on how to set it or use it for my purpose.

hello guys,
First thing is I'm a noob here, totally noob, altough I have used galaxy fit for almost one year now and have tried many, many custom roms here, I think it is already the time that I'm making my own.
So I read many tutorial how to make a custom rom, with dsixda kitchen. I read there on the original thread that dsixda kitchen didn't support our device, but I was persistent, downloaded all the requisites, and skip skip, finally I understand now why, because the file system of DXKT7 is rfs (system.rfs), it must be converted into ext4, or at least has system.img (am I wrong?), so I search every tutorial about converting file system into ext4, and almost all suggest it should be done on the device itself, or should I say, flashing this stock rom via ODIN, root it, and then u can convert it into ext4.
isn't there any way to make it done in PC so I can start edit this rom in kitchen?
I read it somewhere about extracting initframs.cpio from zimage, please, if anyone know this way, please teach me how
any explanation are appreciated, thank u in advance guys, n sorry for my english

not very hard ,just extract initramfs.cpio from the zImage ,add this line
CONFIG_EXT4_FS=y in filesystems,then change Mount points in init.rc of Ramdisk
and then Format All Dev Blocks e.g. System,Data,Cache to ext4 !!

copy system.rfs and csc.rfs from a stock rom and boot.img from custom rom to ur original_update folder and extract it...follow onscreen instructions in the kitchen and use magiciso to extract system folder and then do the mods and all u want and pack it now it will work meta-inf folder will be autogenertaed but replace the update-binary in ur created rom from anyother custom rom and it will surely work

I have unpacked boot.img using advanced options in kitchen's menu, now I have folder ramdisk and zImage, what to do now to convert it to ext4?
oh, I followed ur instruction, extract system.rfs with magicIso and put them together with boot image (the one from stock) and others in original update folder and now I can deodex it.
my question, should I change the boot.img with custom rom's boot image so it can support ext4 file system or just go with the stock?
or how can I change the kernel?
edit : oh, after hours searching I just found this thread, everything I need is here--> http://forum.xda-developers.com/showthread.php?t=1414534
anyway thank u guys.

ur boot.img from stock is rfs format so it wont work if u use that...use boot.img from any custom rom that is also based on ur baseband version(DXKT7)man..the boot.img will automaticaly have the ext4 filesystem(in custom boot.img not stock)....kernel is later part of ur rom man better not go into that now .....copy boot.img from custom rom of ur baseband version then system.rfs and csc.rfs file from stock rom and do as i said above and dont forget to replace update-binary in ur rom after creating the output_zip file from any other custom rom or ur rom wont install
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.

Hello xdawesome forum,
If I want to make my own .zip file to flash it using CWM and boot in some linux distro; say debian, what should be included in this .zip file?
Is it as simple as putting my .img file in a .zip file?
I think your best option is to follow this tuto : whiteboard.ping.se/Android/Debian
If you try to flash directly a debian img, you'll miss some libraries and won't even boot.

I have the stock rom for the Galaxy S6 Cricket variant... I am having trouble in getting the build.prop from the system.img. I have tired many methods from other threads but none seem to work. Any suggestions or working ways to extract the build.prop from the system.img or any way to open up the .img file.
I am doing this to post the rom in the ROM WIP section for the root.

Try the tools in this thread . I used them last week to extract a build prop.
Just load up the system.IMG and drag the file from the system folder to your desktop.

I got your PM. Sorry for the late reply. I'm posting here in case someone else needs the info.
Download Ext2explore.
Extract to your PC.
Run as administrator.
In app: go to file - open image - (find your system image) and open
It will display your image in tree and folder view
Use either one (depending on your preference) (but your build.prop will be in the first view as its in the root of the system).
Right click the file/s you want to extract
Select save
Save your file.......profit
Hope this helps

Hello everyone,
The reason why I wish it to be edited and repack is because I want to change the boot logo(not boot animation) without rooting.
After few hours searching here and there, I found Samsung's boot logo located at BL_[texts].tar.md5
Open it with 7-Zip and open Param.bin, if you like to see it yourself here is a sample:
https://mega.nz/#!bV1XAQ6a!O53nC4V0HNMt3i7Qj6SCN4bxZGtkDqxPQYxSdnh_vm8
I know there's tool to edit and pack the system file but not sure how to do it with BL_[texts].tar.md5 thought
What is the tool available to replace the logo.jpg? Or is it possible to be edited using linux?
Please share what you know, and please don't discourage if you don't know.

Greetings and welcome to assist. I think it may be possible with linux, you can unpack and repack the tar file easy enough and then create a md5 file. I have never done it myself but do know of someone who did this on a verizon device with a locked bootloader
Good Luck

I'm not using any linux OS so I don't know much
1. How to compress tar files and set specific permission to file while compress using linux?
2. Is there any GUI or need to use everything using console?
3. In windows is there any tool available to compress tar file as well?

If you want to use linux there are plenty of prebuilt vm machines at osbox.com, I like linux mint myself as it has a desktop similar to windows. You can also boot linux mint from a usb drive without actually installing it (live mode)
I also found this tool for windows which may work as well
