[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

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

Rom in .img format??

Hey guys
The volume rocker on my HD2 is broken, and I have cLK flashed on my device. My problem is that I can only boot into cLK and fastboot mode as recovery is useless to me because I cant navigate through the options using the volume rocker.
I am looking for a rom (android/winmo) that is a .img file so that I can flash through fastboot, or if any of you know any other possible way I can flash a rom through fastboot so I can get my phone working again. Right now I dont mind which rom I flash, as long as I get my phone in working order again.
All help is GREATLY appreciated....!!!
If anyone also knows how I can compile a rom into a .img file so I can flash through fastboot, that is also welcomed help!

Any ROM you download that is for cLK has a. img file in it. you will have to extract the file from the. zip hou download to find it. Read my post here it will give youthe details on how to flash your ROM.

Hey bud, thanks for the reply, but my question still remains... what about the other 2 folders in the rom folder (META-INF and SYSTEM) what happens with those? lol....

Sorry for the late response but those two files do get used, the img file oules the information from them as it is flashing. To put it simply when you initiate the flash the img does the rest of the work. The img file is sort of like a cab file for Windows Mobile only it is not all self contained and has more functions than just to install the software. Note I said sort of not exactly like, that is just a comparison to help you understand. When you flash a Android ROM via CWM it essentialy just activates the img file to flash the ROM.

Daf roms come as a system.img
or
if you have access to another hd2, flash the target rom to it and then use mkyaffs2img command in the terminal to dump the system folder to a system.img file.
Benefit of this would be you can tweak the rom(reduce size for example, by removing unwanted apps) before you dump to system.img

Thanks for getting back to me buddy! Unfortunately I dont have a second HD2, and I dont know anyone willing to help me out in Greece, lol... Would you be willing to dump your system folder for me and upload it so I can use yours?? I would GREATLY appreciate the help... sitting with my HD2 "semi" bricked... lol
Also, if I use the .img file from the DAF roms, can I flash it using fastboot??? You have any suggestions on how I can flash it considering I cant use the volume rocker on my mobile?

Well id like to say yes but it's Easter weekend and my sons 1st birthday tomorrow, so the likelihood of getting near a PC are slim for a few days.
You could always learn how to use the android emulator,, build the image on a virtual hd2
As for flashing,,, no idea, no clue what fastboot does, magldr for me, but in your OP you implied you could use it to write img files to partitions.

You ever got a solution for this? I'm in the exact same situation right now.

Which setup are you using?
Are you using a setup that requires an SD-EXT partition? Do you have one?
Edit the configuration file in the recovery folder (called config.cfg or something) and make the system 300 (if using dataOnExt), then reinstall recovery, then ROM.

flash.cfg, not to be confused with flash.cfg.txt in teh same folder. (If you only see files called flash and flash.cfg, , , flash is flash.cfg, flash.cfg is flash.cfg.txt and means you have 'hide file extensions for known filetypes' turned on)

Newer threads/tutorials on making system.img to zip

Trying to flash CopperheadOS with multirom on N6P.
But I can't flash the image in TWRP so I'm trying create a flashable zip.
But problem is all the guides and tutorial are very outdated (with most of them mentioning "Android Kitchen")
Where should I go to find help for this?

If you are on the latest TWRP, you can flash an image file to the system partition by clicking the Install Image button when selecting a file to install.

That way doesn't work because I use multirom, it has a modified TWRP (it's still the latest version doh)

Sorry for shameful bump but I can't find an answer whatsoever

In what I have been able to find there was a META-INF folder that was a part of the back-ups now all I see from my stock backup is .win files, not tar.md5
Now I can guess that the naming is still similar so can you compress the system.ex4 files and have the same process with a file format change.
