[Q] How to load system.img?

I've compiled and installed a modded kernel. I'm trying to figure out how to load AOSP compiled binaries. I've tried using adb flash_image system /sdcard/system.img, but I get "failed with error: 6." Does anyone know what this means or how to load system.img on a Galaxy Tab from VZW? I'm working on reactivating the phone dialer...

the galaxy tab has nothing like fastboot, so its pretty hard to flash it! but u can try to overwrite a stock factory.rfs with the files from ur system.img and flash via odin!

That sounds like a great idea. However, I'm trying to figure out how to put the vendor specific drivers in the system.img, which is mountable and editable. If I could get my hands on an original stock system.img, that'd be awesome.

As far as I know, the Tab doesn't use mtd file system, so I don't think it uses .img extensions.
Not positive though. Somebody correct me if I'm wrong.

I know for a fact that img files are created as the output of an Android system build. This img can be broken apart with standard Linux tools. I've already done this. I've also mounted factoryfs.rfs to a local directory, which allows me to move apps to and from the file system.

If you have a md5 of it too, you should be able to flash it via an advanced restore in CWM recovery. That is if it is only the data that is flashed to /system. otherwise I would suggest converting it to a .fs or .tar and flash via heimdall or Odin (respectively).

What PC tools can I use to open .img files in a nandroid/CWM backup set?
Must I set up an Android ROM cooking kitchen using Virtual Box + Ubuntu, or is there another way?

use the attached unyaffs.exe to extract a system.img! simply drag the created system.img onto unyaffs.exe and it will extract alle the files in the same directory!
to rebuild, i think it might be able to create a image file in magic disk maker but im not sure

You're doing something wrong. Make sure the image you are trying to unyaffs is in its own empty folder. After unyaffs remove the .img from that folder. Then create new image file by running the mkfs.yaffs2 as follows: mkfs.yaffs2 /home/killahurtz/Desktop/location of extracted system.img/ system.img

~/Desktop/newrom$ mkfs.yaffs2 /home/filefixer/Desktop/newrom/ system.img
mkfs.yaffs2: Android YAFFS2 Tool,Build by PowerGUI

Build Ok.
Into newrom folder no system.img file when go to create image. Just unpacked files and folders without system.img.
After that, system.img is corectly created but have 2GB.

Please attatch a screencap before and after you run the mkfs.yaffs2 command. Please be sure that the target directy is clearly visible.

There is the problem...
First picture is when unyaffs and second is when create image file after mkfs.yaffs2.

I don't think your output path should be in the same folder you're trying to make an image from. That's the problem
Fix that and i'm positive it will work. Hope that helps.

I tried this method and system.img is created in new folder but this sistem.img no contains folders and files from /newrom folder. It contain a files from my Ubuntu system folder?!
I am confused...

ok have system.img in newrom folder in Desktop.
1.open terminal
2.cd Desktop/newrom
3.unyaffs system.img
4.now go remove the system.img file from your newrom directory
5.if you didn't close terminal type "cd.." to change path back to Desktop
6.mkfsyaffs newrom/ system.img

The attached should be all you need. split_updata.pl will extract the system image which you can then mount directly. splitfile.c will extract the mbn files and boot.img. Use abootimg to extract the kernel and initrd and then cpio to get the root fs from the initrd. Obviously you will want to use a linux box for this.

--Open a command window and set the directory where you have .jar file.
--Now type sgs2toext4.jar and press enter.
--The .jar will run in a new window & will ask you to drag & drop the system.img file there. Do the same and wait till the process completes.

Unfortunately this doesn't work. When you drop the system.img.ext4 file onto the sgs2ext4 tool, no file is produced. The tool just keeps endlessly repeating:
"system.img.ext4 32 B 0 B/s"
I think that tool is too old (2.5 years old) and doesn't support the newest Samsung firmwares.

The T-Mobile Galaxy Note 4 (SM-N910T) NK4 firmware. I can't find any instructions online on extracting Samsung firmwares other than these, which were originally written up by rwilco12 a long time ago and reposted endlessly.

I found that the Linux method works on my Mac. Took a ton of tinkering and restarting the emulator on my machine.
sgs2ext4.jar did not work for me in Windows. It just hangs.

The SAMMOBILE firmware or the system.img? I'm not yet downloading it. Let's see if I can resume the download.

How can i unpack boot.img?

I want to custom kernel without magisk.
So i tried to unpack boot.img in order to modify kernel in boot.img.
But, i couldn't unpack boot.img with any other unpack tool like Android image kitchen.
Common problem is about ramdisk.
i guess common unpack tools can't unpack pie 9.0 boot.img.
so i used different ways flashing other rom's boot.img because of using recent custom kernel. However, it is just temporary action.
do you know any other ways to unpack boot.img?

You can unpack any boot image if you have the right tools. If the problem is with unpacking the ramdisk, that would be because you are trying to use the wrong tool to decompress it. Open the ramdisk image with an hex editor, and post the values of the first 4 bytes. And then tell us which tool you are trying to use to decompress it.

Why ramdisk is empty?
Bro I have redmi note 7 pro
when I unpack boot.IMG , ramdisk folder is always empty
Why ?
is there something that I missing?
