How to extract system.img

Hi all,
I am trying to develop a rom but I came along this difficulty: I can't find the sysyem.img. I tried to download a .zip file, only the folder named "system" came in it. And I tried it with a .exe and looked in "%TEMP%" no luck either...
Can anyone explain how I should extract the system.img?
Thanks in advance.

I guess your referring to a nandroid backup really. When you download a rom, it comes in a zip file which you can flash and has only a boot.img file (I think, can't remember off top of my head) so it can boot. It doesn't have anything else. You only see a system.img file when you do a nandroid backup. Everything that is in the system.img file is still the same as the system folder in a zip file.. more or less.

If you do have a system folder, it is possible to convert it using the HTC Kitchen

That should help heaps with ROM development

Can you please explain to me how I can convert the system folder, I don't have a clue.

Convert it how? How do you want to convert the system folder? And why? Might help us out more you know.

On "Theunlockr" (My guide for making a rom) It says
"If you have a .zip file, you can unpack the system.img and boot.img"
I only have the boot.img and a system folder!
And it also says: "If you have a .exe, run it until the first screen and then go to run and type %TEMP% and a rom.zip should be here"
in both cases it is not the case.
So, can anyone help me out please?

[Q] How to install *.rar file in HTC HD7

Can anyone guide me on how to install *.rar file to my HTC HD&?
Appreciate your guidance.

Made a mistake.

.rar is just an archive. What exactly do you mean by "installing .rar into device"?...

Got it.. thanks..

Extract camera.apk form recovery image

I made my phone image with ClockModRecovery.
And I got:
boot.img
cache.yaffs2.img
cache.yaffs2.img
recovery.img
system.yaffs2.img
.android_secure.vfat.tar
sd-ext.ext3.tar
Where I can find Camera.apk?
I tried to find without success...

It should be inside system. Yaffs or sd-ext depending on if you use an a2sd script. You'll have to unpack it somehow.
Btw, why do you need it. It should be delivered with your rom.

I extracted all img and tar
except boot.img and recovery.img because cannot open
and searched in all extracted files and cannot find camera.apk
I found:
s.system.app.HTCCamera.apk
(this is looks like original camera but this is cache
\data\com.estrongs.android.pop\cache\.apps)
s.sdcard.HDR_Camera_v2.0[szoheb].apk
s.sdcard.backups.apps.Paper Camera-17.apk

I am not sure what you mean by that first apk. But if it is from system/apps it should be the original one.
Could you explain more detailed what you mean by it looks like but isn't?

creating a rom out of a original RUU

can anybody guide me through making a flashable zip from a rom.zip which i gained from a original RUU for my branded HTC one X? Problem here is that this ROM i want to create should not contain or do any hboot/firmwares updates as currently i am on a higher base then the current available RUUs for my phone. So because of this i cannot just install the original RUU to go back to the original branded ROM. Somebody told me that i have to take out the system.img to achive my goal, so thats what i also tried. i Extracted the system.img out of the rom.Zip and placed it in a new rom.zip folder without all the hboot.img and oder files.
This is how far i am for sow now:
-extracted the rom zip out of the ruu
-installed dsixdas ANdroid rom kichten
- did set up a working folder with the rom.zip from the original ruu
-tried to build a new rom out of the working folder in two ways ->
1. with the whole rom.zip containing everything original
2. rom.zip just containing the system.img
everytime i try to flash the built zip file, it gives me error in /sdcard/update.zip status 0 in recovery.
Is that right that i have to flash the stock kernel and recovery.img after sucessful flashing my own rom? What else should i do? Hope somebody could help me out!
what do i have to do now?
My main goal is to go back to my original branded rom so i can do the OTA updates which are available.
thank u in advance

I tried the same things you did, My device is HTC Explorer (Pico) and got the same error message while flushing. You cant try putting META-INF folder from other custom rom and try to rebuild the rom. this trick worked for me once. I am no expert of creating rom I am a complete noob just sharing my experience. Do it with your own risk. Sorry for my bad English.

proplem flashing xenon hd

iam gtrying to flash the old version of xenon hd wich is 11.1 now every time i try to flash never complete always abort by the way hboot is 1.72 help please if you can

Think you need to update the updater script in the meta inf folder of the rom. You need to add your hboot number

aaah can u plz explain how??

Open the ZIP with 7zip and take out the updater script. Open that with notepad++ and change for instance 1.39 with 1.72. Safe the file and insert it in the rom.zip and flash the rom again

i am sorry man i couldn't recognise the file would you plz mention it's name and the folder where it should be

Open the rom zip and unfold all the folders under META-INF check every folder, you see soon a file called updater-script. That's the one you need......
