Building android: noob warning

Howdy,
I just built and installed android 1.1 on my dev w/o major problems. But how do you create an update.zip? I tried dumping system.img,userdata.img and root.img into a zip file, but it failed to verify with a signature error.
Thanks for any help!

Might sound like a silly question, but did you sign the update.zip?

Nope. Is there a tutorial on how to sign? (btw, I'm on either OS X or Linux).
Thanks!

all u had to do is take a look over at the theme subforum and u would have found this:
http://forum.xda-developers.com/showthread.php?t=471586
it has apk signer and .zip signer as well

Thanks! I appreciate it

Never mind. It looks like the sdk has the java tools I'll need

reviving old thread, i searched and this is all i could find related to what i'm asking. I downloaded a system.img and boot.img that are very, very, very bare. They're almost stock android (nothing but the system, phone, camera, settings, calendar, calculator, and alarm). there aren't even any ringtones, notifications, ui sounds, or alarms. nothing. the thing is bare, i think even the drivers are broken because i can't end calls. anyway, this is perfect for me because i want to use it to study android and get more acquainted with it before i start actually building from source. I pretty much want to know what every single file does and what files apks depend on. Anyway, this rom is good for study, but i want to be able to make an update out of it once i start adding things, but how do i go about extracting all files from the system and boot imgs?

Old cooker want to cook something

After many many tweaking and cooking ROMs for WinMo I want to do same with Android. The reason I cooked for WinMo was speed, but since it is not an issue with mine Desire(but it can be better I want to customize ROM a little bit, so remove some stuff and later maybe add few apps. If this want be a problem I will try to tweak too.
However in WinMo I have always have served kitchen, I just tweaked removed and add few things and job done but here there are no kitchens..yet(I hope somebody will sooner or later post it
So is there anybody who can help to set up kitchen so that I can cook few roms for me and this community?
So if I understanded correctly I need following to start cooking
android sdk
java jdk
signing tool
stock ROM
I have downloaded them all, extracted SDK in D:\HTC Desire\Android SDK, installed Java JDK in C:\Program Files (x86)\Java and I don't know what to do next?
Extract ROM, where(?), extract system.img which is in rom.zip if yes how and where?
Thanks for your help

Benko, you can extract the ROM anywhere you want. But, you don't want images. You should look at Pauls rootedupdate.zip as a starting point. Unzip that.

Ok extracted that rootedupdate.zip and found a lot of apks and obexes so after I delete those files that I dont want how to put that all back together to file that is flashable?

You'll have to resign the zip after removing stuff, otherwise it will give verification errors when trying to flash.
You need to remove the current certificates from the file, there are three files in the META-INF folder - delete those, but keep the update script (the COM folder inside), it's needed for flashing.
I use this little thingy for signatures: http://android-dls.com/wiki/index.php?title=Generating_Keys
Hope this helps!
PS-beware of any dependencies between the various apk's and any framework modding that might be needed, otherwise you'll get more fc's than you can carry; I know I did
PS2- if you want a served kitchen, you'll find one over at Modaco, for a CyanogenMod port (a link is posted in a thread here) - see if that suits you're needs.
PS3- check out the Chef Central sticky here, too - it should be easier to get quicker/more accurate info from the seasoned cooks there

Rezip the folders: meta, system & boot.img.
Then resign them. You can then transfer it to sd and try to flash. If it doesn't boot, then you have to troubleshoot.

May I know that how to change layout of the home screen?
e.g. HTC sense has news/mail widget where first installed and booted.
Where can I change these settings?
Also , I want to know if I made my own rom, and updated to my desire.
If it doesn't boot or anything, can I updated the rootedupdate.zip from Paul to get the desire back working?
Thanks

Ok zipped those folders(META-INF, system, boot.img) in rootedupdate.zip, used autosign.bat to manually sign that .zip and now it should be flashable?
@Kevin-yes if it is not bootable you can flash Pauls rom again

Hopefully. After a few hundred times you'll get the hang of it. ;P
If it boot loops, it won't boot. Try again. Always remember what you're adding and subtracting. Maybe start out with only a couple things.

Uploading it now
Some very very bad battery leaking...80% in one night and sync was off!
Thank you so much eViL D: and everybody else for help

Ok I also want to create my own rom but I don't know how to sign it..
Any help would be most appreciated.

ROM Link here

I hope it works
So for now I even don't need Android SDK?

I downloaded the rom kitchen from Chef Central...Does the rom need to be sign after I built them out in Linux?
Also there are some folders I not understand yet....
Inside system folder - customize, etc, framework, usr and xbin I dont understand yet.
Cause looking at eVil D:'s rom and paul's rom is very different in those. And even paul's rom doesnt have customize folder.
Would like to understand all and see if I can make a rom out.
Thanks

Anybody tried my ROM ?

the kitchen signs the rom automatically. run the menu from terminal ( using linux) and u will see all the what the kitchen is doing.
do not try to compare custom roms ... they are different. some have extrafiles & folders depending on their customisations.
best thing is to compare with an original rom for the desire. and u see what has been added to get X and Y. involves a lot of trials and errors.

[Q] Trying to update Xoom 4G, but I removed dungeondefenders.odex, I have system.img

I just can't find a way to extract what is in the .img files.
It's such a small file so shouldn't be hard to find.
Downloading it from the Play store does not resolve the issue
How can I re-acquire the needed .odex file and/or extract what I may need from the .img files?

Do you have a Backup of your system - if so restore your backup. If not google extract .img files and look for software.

No backup...I just need to find a way to extract the files from the .img files of which I did google but nothing useful came up

Why the hell is it impossible for someone to find a way to get such a small measly file to get this stupid update to go through!!

Which update are you trying to apply? You will need the pre-updated file. 4g updates were 3.2.4 and 3.2.6.

I'm on 3.2.4 and trying to update to whatever it's asking me to update it to.

Because that's the first thing you do when you are going to flash stuff. If you had done this the first time you wouldn't be in this situation.

First of all, thank you heaps LameMonster82, you are an absolute champion!!. I was searching for hours to find a kdz file for G710EM10p and your posting was the only one I found. For some reason the "thaks" buttob isn't visible to me.. maybe because I'm a new member.
I thought I could be helpful by listing the different KDZ files which are in your google drive folder so other people can find them while searching through google like I was.
In the above link from LameMonster82 there are following KDZ files for the LM-G710EM (European) variant of the LG G7 :
G710EM10b
G710EM10f
G710EM10k
G710EM10p
For the LG V40:
V405UA10c
V405UA10l
To install the KDZ file follow the guide here: https://forum.xda-developers.com/lg-g7-thinq/how-to/guide-how-to-flash-stock-firmware-lock-t3820888
Thanks again

I am having problem downloading G710EM10p kdz file, is there perhaps an alternative download link?

Download manages to get to 1 GB and then it drastically slows down and eventually fails. Via a download manager the farthest I got was 1,5 GB: although the download manager continued to download (it downloaded ~5 GB of data), the file was only 1,5 GB.

Doesn't seem to be something from me. Maybe Google's server are acting up or youre using your phone to download it. If you're using a phone it will sometimes do that. Try downloading another file and if not find a 10p version here: https://lg-firmwares.com/lg-lmg710em-firmwares/#tab=firmwares

I managed to download it! It went fine this time, I did not change anything on my side.
Thanks!

It's the system partition but it's empty because when you install an update the system copies there. A/B support

Is it possible to extract any of the system apk files from the image without it being flashed?

Of course. You just need a 7Zip or WinRAR to open the image and fish it out
