I want to build an own ROM, well at least try.
After few experiments -with different success- I modded existing custom ROMs.
Now I want to release an own modded ROM and for that I need a CWM-version of Stock ROM OR -better- Ho I can convert StockROM to CWM-zip.

I think after you extract and mod system.rfs you should use dsixda kitchen to make the rom and add the boot.img file to zip file created then use CWM to Install the rom
The most important thing is after u have created your system,boot.img and other folder if u added a new folder in your base rom then u need to make a updater script .B-)
Sent from my GT-S5830 using xda premium
Yea but still if I place extracted system rfs AND boot.img from CSC how do I get a running updatescript, respectively what has to be in such an update script?
Don´t tell me "just place metainf folder from out of any other rom into it", cuz in that early dev-phase the metainfs of all other roms are useless, cuz they are almost ext4 and the "just extracted stock" isn´t ext4 so the metainfs of the other ROMs won´t work. ^^
Anyone else to help here?
from some Update-script i think you should do those step:
Remember end each script with ";"
Code:
unmount ("/system")[COLOR="red"];[/COLOR]
1-Format all system like you install new Windows
Code:
format("[COLOR="red"]ext4[/COLOR]", "EMMC", "/dev/block/stl[COLOR="Red"]12[/COLOR]")
Change the red with right values: rfs,ext2,3,4(file system), 12 or 13 or 14( system,data,cache partition)
With ext4 you must have a kernel support ext4
2-After format you have to mount them to copy files
Code:
mount("[COLOR="red"]ext4[/COLOR]", "EMMC", "/dev/block/stl[COLOR="red"]12[/COLOR]", "/[COLOR="red"]system[/COLOR]")
3-Extract files from zip to ROM
Code:
package_extract_dir("[COLOR="red"]system[/COLOR]", "/[COLOR="red"]system[/COLOR]")
extract system folder in ZIP to /system
Do same thing to data, cache if you have them in ZIP.
4-Fix permission
nah i dont know to much about this
You have to change permission to right state if not i dont know what happen next
Code:
set_perm([COLOR="Red"]0[/COLOR], [COLOR="red"]0[/COLOR], [COLOR="red"]0777[/COLOR], "[COLOR="red"]/system/bin/a2sd[/COLOR]")
Set permission to one file or one folder(not its contain)
Code:
set_perm_recursive ([COLOR="red"]0[/COLOR], [COLOR="red"]0[/COLOR], [COLOR="red"]0755[/COLOR], [COLOR="red"]0644[/COLOR], "[COLOR="red"]/system[/COLOR]")
Set permission to it and all thing in it
5- Link file
ahh hard to know
You should ask someone else but me
Code:
symlink [COLOR="red"]busybox[/COLOR] [COLOR="red"]SYSTEM:xbin/zcip[/COLOR]
6- Unmount partition
Code:
unmount("[COLOR="Red"]/system[/COLOR]")
And if you have your own boot.img
Code:
assert(package_extract_file("boot.img", "/tmp/boot.img"),
write_raw_image("/tmp/boot.img", "boot"),
delete("/tmp/boot.img"));
This is really basic. So may be it wont work

Anyone: how to compile kernel for fit? I almost give up cause i dont know much about linux, I tried samsugn source but my device never boot. If anyone could help this Noob, Noob 's very thank you
Thank you very much. This should be helpful
Hi, i'm trying to flash my custom kernel with CWM recovery. I've seen some zip to update TF's kernel that use a kernelblob but i didn't realized how to create this binary file.
I've compiled kernel from source code from AsusTek files (Eee Pad Kernel Code for Android 3.2 OS (V8.6.5.7)) and i have zImage and modules (.ko).
Someone know how can i pack this things to flash my kernel with CWM?

Just to create a CWM compatible kernel zip , it's a combination of the things below:
1) Fetch one of the many kernel zip files like from Roach or Clemsyn that are in the development forum to use as a template. Unzip it somewhere in a clean folder and you'll just be replacing modules & zImage (or whatever it is called, almost certainly *blob* something) then next step.
2) Most of what you need to create the insecure boot image is in here:
http://forum.xda-developers.com/showthread.php?t=1193737
3) Most of what you need to create the new blob is in here:
http://forum.xda-developers.com/showthread.php?t=1068548&highlight=blobpack
4) Now move your new modules from your freshly built custom kernel (do a $find {kerneldir} -iname '*.ko' ). Copy them over /system/lib/modules/* in the unzipped template zip from 1) and get rid of any that you didn't create yourself as well.
4.5) copy the blobpack'd file you created from zImage to whatever it was called in the unzipped zip template (say, boot.img to blob or kernelblob or whatever it was called so the script in the zip works).
5) zip the entire contents making sure you're starting at the right base directory into a new customized zip file. That's it you're done. If it doesn't work you might just have created a bum kernel.
Theory of this in a nutshell. There is no way to do the anykernel.zip method because the tf101 will only accept a blob on those encoded partitions so you have to get the blob and boot tools and use them and since all of the kernel zipfiles use it, you've got easy templates.
I'm not mentioning CWM in here because you would just have to create a bigger blob which is I think covered in any thread you search out that has 'blobpack' in it, like Rayman's. The catch-22 of doing recovery + kernel in one blob is that you have no way to boot the thing should things go haywire, unless you're just talking about CWM and it's kernel.
Good luck -
Hashi
Thanks, I blobbed my custom zImage.
I used this zip update as template: http://forum.xda-developers.com/showthread.php?t=1226717
I'll post this kernel with raw hid input support after testing all the functionalities!
Introduction
You probably know already that starting from Android 5.x (Lollipop) compiled roms (aosp,cm,stock) are not compressed anymore the way they used to be on previous android versions. On previous versions all content inside /system folder that has to be extracted within our device was either uncompressed (simple /system folder inside our flashable zip) or compressed in a system.img file, which it is a ext4 compressed file; both of these, anyway, were readable and we could see all system files (app,framework, etc).
The problem comes in >=5.0 versions, this method is not used anymore. Why? Because roms started to be always larger, so it is necessary to compress them even more.
What does new Android zips (full roms, but also otas) contain?
New Android flashable zips are made this way:
boot.img (kernel)
file_contexts (selinux related)
META-INF (folder containing scripts)
system.new.dat (compressed /system partition)
system.patch.dat (for OTAs)
system.transfer.list (see explanation below)
What does updater-script contains then?
The updater-script uses a brand new function: block_image_update(), this method basically decompresses necessary files inside the device. Let's study it.
From google git source code, if we go inside the new file /bootable/recovery/updater/blockimg.c, we find at the end of it the registration of the function block_image_update() as the method BlockImageUpdateFn() which starts at line 254. Here finally we find all information we need to know about the decompression of the .dat file(s). First file we analyze is system.transfer.list which Google tells us:
The transfer list is a text file containing commands to transfer data from one place to another on the target partition.

But what each line means?:
First line is the version number of the transfer list; 1 for android 5.0.x, 2 for android 5.1.x, 3 for android 6.0.x, 4 for android 7.x/8.x
Second line is the total number of blocks being written
Third line is how many stash entries are needed simultaneously (only on versions >= 2)
Fourth line is the maximum number of blocks that will be stashed simultaneously (only on versions >= 2)
Fifth line and subsequent lines are all individual transfer commands.

Ok, but how to decompress the system.new.dat file?
All instructions are below. sdat2img, rimg2sdat and img2sdat binaries are involved. Please read carefully step by step.
NOTE for OTAs
If you are looking on decompressing system.patch.dat file or .p files, therefore reproduce the patching system on your PC, check imgpatchtools out by @erfanoabdi.
You can use/modify these files and/or include them in your work as long as proper credits and a link to this thread are given.
If you have questions or problems write here
Are you building from source and want to revert to the old flashing method without DAT files?

Ubuntu
Ubuntu 64-bit - Guide
Step 1 - Decompressing = DAT (sparse data) -> EXT4 (raw image)
We're now using sdat2img binary, the usage is very simple (make sure you have python 2.7+ installed):
./sdat2img.py <transfer_list> <system_new_file> [system_img]- <transfer_list> = input, system.transfer.list from rom zip
- <system_new_file> = input, system.new.dat from rom zip
- [system_img] = output ext4 raw image file
and a quick example:
./sdat2img.py system.transfer.list system.new.dat system.imgby running this command you will get as output the file my_new_system.img which is the raw ext4 image.
Step 2 - Decompress EXT4 (raw image) -> OUTPUT folder -> Compress EXT4 (raw image)
Now we need to mount or ext4 raw image into an output folder so we can see apks/jars etc.
To do this we need to type this command:
sudo mount -t ext4 -o loop system.img output/As you can see there is a new folder called output which we can edit/modify/delete your files (not able to? see here)
Now we need to compress it back to a raw ext4 image, to do this we need the make_ext4fs binary. Make sure you have the file_contexts file (taken from the Rom zip) inside the make_ext4fs path. Then type this (got issues? see here)
./make_ext4fs -T 0 -S file_contexts -l 1073741824 -a system system_new.img output/You will get the new raw ext4 image called 'system_new.img' ready for the next step.
Step 3 - Converting = EXT4 (raw image) -> IMG (sparse image)
Now we need to convert the ext4 raw image into a sparse image. For this you need img2simg binary you can find here (thx to @A.S._id).
The usage is simple:
img2simg <raw_image_file> <sparse_image_file>Pretty self-explanatory, the output will be a new sparse image (.img).
Step 4 - Converting = IMG (sparse image) -> DAT (sparse data)
Now we need the img2sdat binary, the usage is very simple (make sure you have python 2.7+ installed):
./img2sdat.py <system_img>- <system_img> = name of input sparse image file (from step 3)
As you can see the output is composed by system.transfer.list, (system.patch.dat) & system.new.dat, ready to be replaced inside your Rom zip.

Step 2 - Decompress EXT4 (raw image) -> OUTPUT folder -> Compress EXT4 (raw image)
Now you should either move to Ubuntu x64/x86 or follow the 2nd step from the Ubuntu guide on cygwin 32 bit.
Step 3 - Converting = EXT4 (raw image) -> IMG (sparse image)
Now we need to convert the ext4 raw image into a sparse image. For this you need img2simg binary you can find here (thx to @A.S._id).

i don't think so, though you can install ubuntu in a virtual machine as 64-bit and decompress there without problems.

Works perfectly..
Thanks a lot! This will save a lot of time theming.. (pulling the system, settings, framework without having to flash the rom first)
Oh, just for s&g's i extracted ("decompiled") the system.new file, the files (app, prive-app, framework, media, etc) all got placed on my desktop -- i deleted the system.new file from the rom -- i then placed the folders and files that got extracted and placed them in the rom -- i flashed it -- it booted! lol.. didnt think it would... but anyways, there's that.
For those who want to try:
--- > its basically self explanatory.
- once downloaded (the link above) extract the contents from the zip (i just went ahead and extracted to my desktop)
- right click the linux penguin
- run as administrator - the window will pop up
- go to file > open image > find your system.new image (should already be extracted from the rom and placed on your desktop)
- click open
- you should now see your image (or path) in the windows -- double click them (i doubled clicked both the right and left side)
- now you should be able to see all the folders
---> if you want to extract those folders
- just go up to the top
- click save and choose an extraction (i chose Desktop)
Hoped i helped -- any questions or confusion, dont be shy to ask -- i probably went too fast, idk lol
Enjoy!

I can't get this to work at all. I'm using Win 7 Pro and I've actually used this app before with stock Nexus 7 factory images and it worked fine.. What file did you actually download? I d/l 2 different versions, one was beta 2.0 and the other was a zip that said 2.2.71 but the about on the exe says 2.1, which is the version I've been using for quite a while.
With the beta 2.0, there's not even an option to open a file and with the 2.1, it errors out every time. After opening system.new.dat image and double clicking, it just hangs and the program stops responding. If I try clicking on it and selecting save, it allows me to select a folder to save it in but I just get a dialog box that says saving files and then hangs at 24% every time, finally crashing with a Microsoft C++ runtime error.
Oh btw, you didn't go too fast LOL, this is really a simple app to use but it's just not working for me with these block image files. Maybe I'm missing something but it's got me scratching my head. :laugh: If you have any ideas, I'm all ears.

EDIT: Ok, i lied.. i just checked my trash.. i did download the lastest release .zip .. the 2271..
@webdroidmt @Incredible_Culp Download from here lol: http://sourceforge.net/projects/ext2read/
Maybe something with my PC setup or Win 7 because the 2006-8-26 version doesn't even give me an option for opening a file image. It actually loads up looking like an incomplete application, it's also a very small filesize. Did you just d/l the ext2explore exe, or did you also d/l ext2read2 beta zip?
