How to create update.zip

Guys, I wanted to learn how to make one. I know the basics, but wanted to know what language it's written in and what are all the functions it supports and their syntax.
Where can I find this information? I tried searching but did not find anything.
edit: found a very helpful thread, http://forum.xda-developers.com/showthread.php?t=641223

making an update.zip isn't that hard, the only part that actually requires a bit of learning or familiarity is the update-script. just look at examples from themes and ROMs, and you'll likely get the hang of it really quickly. lastly, use a signing utility(i use autosign).

Thanks. Someone else had mentioned that. I did start looking the script and the update.zip file. But I wanted to figure out additional commands. What other functions are available for our disposal.

You searched it good alright. Let's see what 'make update.zip' comes up with on google. Oh my gosh, HOW TO MAKE UPDATE.ZIP FOR ANDROID PHONES.

Thanks hot shot.
Why dont you follow that link and see what it says for yourself. None of the links give me what i want. I already know that I can backwards engineer a update.zip. That's trivial.
I want to know other commands that are available. Someone has to know. Unless even the devs started to just modify old zips and go from there. That I can do too.
I swear there are people like you just searching threads to post such remarks instead of real technical or meaningfull posts.

okay I found some syntax for update script. Check out this thread.

[Q] Unpacking system.img from Flyer RUU

Hello Nookers,
Remember that Sense 3.0 Port for Nook Project a long time ago? Well, the thread got closed because there wasn't a full product ready.
I'm almost done with my first working Sense Port, but I just need one more thing. First, lemme explain. These apps fail to works because the dump I used was an EVO View 4G dump, not the Wifi-Flyer's dump. So I have now managed to get a hold of a Deodexed Flyer RUU. I have extracted the ROM.zip containing system.img, data.img, etc. What I need now is a way to extract files from those. I have access to a Mac and PC but if ABSOLUTELY NECESSARY I will install Linux.
Thanks,
King Black Bomb.
Moo

if they are img files you can use IM disk to mount the img file on your PC. then you can access them and remove the files that you need to remove.

Dude, before you got banned two weeks ago, you said this would be done in 4 days, and you are still working on it? This is why you are not considered a credible developer.
You can use winimage to extract img files.

As I agree with the user above about your lack of credibility I'll add some info here for you to try to achieve your task. Attached is the program I use to extract images. ALL YOU DO IS DROP THE IMG FILE ON THE EXE AND IT WILL EXTRACT.

Yes, I did say that, and it was a mistake on my part I thought I would have found the program by then. Turns out a didn't. @xboxexpert I have tried unyaffs it does not work on either Mac or Windows. WinImage? It doesn't work. For some reason it seems encrypted. Same for IMDisk.

why are you even still trying this? HTC HAS MADE SENSE OPEN SOURCE AND WILL BE RELEASED ANY DAY NOW. www.htcdev.com

As I understand it, there aren't plans to make HTC Sense open source. This simply lets you write applications that make use of HTC Sense-specific APIs.

Woohoo, more free lawls! Get 'em while they're hot!
The kid has been stuck on the same step for several months, regardless of whichever RUU he stumbles upon on bittorrent. It's pretty pathetic at this point...

did you extract the exe from the rar?

You really need to read his old thread to understand -- in it, I was one of the only members trying to help him... at first. He proceeded to dismiss everyone's guidance -- consistently claiming to know better -- and continued to lie about "progress" for weeks. The extent of his "development" was copying and pasting the Sense apk's into /system... seriously.
There's history here with this clown, so please save your judgments for someone else...

You can try DiskInternals Linux Reader:

OK, so you need to extract system.img files. You don't have to install Linux, you can run it from a Live CD. And mount loop the .img file to a folder on your system.
Mind PM'ing me a link to the download so I can do so for you? Then you can go ahead and do the port as you would say?
-Racks

To everyone who says I'm not a dev:
I have been making progress, because at first it was complaining about audio drivers, then files in /system/etc, and it kept on going. Finally, and i THINK this is the last step, is to push Wifi-Only frameworks, apks, and the /system/etc folder.
@racks11479 thanks, but I'll only tell others to do my work if I can't. But again thanks for offering.

What are you talking about, aren't you saying you need help extracting the system.img? I'm offering to help...
Isn't that the particular request you are asking in your OP? This is a developer community, everyone here welcomes help where needed. Not one developer on this forum has ever denied any help when they were stuck on an issue.
Not flaming you, but trying to help so you can continue the port you are working on. Don't let pride get in the way of progress.

No not pride, it's just as soon as I say yes people will say "oh, the kid need serious help. Can't even extract a system.img."

Frankly, they have been saying that for some time now.
As it is, this thread has NOTHING to do with the nook, and needs to be closed. Frankly, i wish you would refrain from making these posts. It is obvious that you have no idea what is going on, and your posts are only serving to make this public info. I welcome everyone working on their dev skills, but strongly encourage those who are learning, to post about it in the right way....

(Q) Walkthrought

Can you guys provide a walkthrought on how to quickly add a device by merging this code and the device source code?
What to look for in source, where to place it
How to safely test it, etc
With this walkthrought you can get users quickly enabled to start on creating support for their own devices as wel as more community maintainership
pretty pretty pretty please

We have a load to document, and we will be doing it as quickly as possible. We can provide a guide on how to go from AOSP => Omni quickly. It's a bit complex to explain how to safely test on any device, as that depends on specific per-device knowledge that a developer of that device has.
But we'll do our best to help people get building

Vendor is the manufacturer i believe. OR the devices code name. Ex. HTC EVO 4G is the supersonic and HTC EVO 4G LTE is the Jewel.

Well i gathered that part (been catching up on my source lingo) what i meant is finding the add new device commit on ominirom vendor commit. I guess i need to see some example? Ominirom vendor is listed as android_vendor_custom if you want to take a look

I would say normally not, but I believe it's that the omni source isn't finished on github.
Edit, I believe, if I remember correctly, one on the device trees on the manifest to be synced isn't on their github. Which will probably be fixed soon enough.
Just because one is anonymous doesn't mean that one has privacy.

syncing going on. I got a lg g2 d802 with sources from lg,
Am starting an experiment. Wont get the speed anywhere near the pros.
I got sources from LG for the 4.2.2 rom. Will this be a version de mismatch with 4.3?
Now I need to add\edit some files. No walkthrough for that yet.
Anybody has a good hook on where I can check next steps? I was thinking probably along the lines in this post:

Help with 1 upstream

Hi guys.
With one guy, who doesn't have Huawei phone, we try to debug why 3.10.90 isn't booting, but logcat seems that everything is okkey, and cat /proc/kmsg and other adb shell commands gives errors. So I try go get a help, could someone upstream the following kernel (3.10.89) to 3.10.90 and make it bootable too ? I tried it for 4 days, modifying ramdisk, etcetc... nothing worked... couldn't debug cuz adb shell wasn't working(i mean it was working, but next commands weren't, i even installed adb insecure ap, usb debugg on etc).
@XTutorials @surdu_petru @haky 86 @XePeleato(if you know somehow ) @DingDongPow or others. Thanks!
https://ufile.io/rvlmk (why no github ? 1. ffs can't even upload it there 2. only when i finish the upstreams)

You must learn to crawl before you can walk.
In the first place you are debugging userspace when the change you made was in the kernel, obviously you aren't catching the error, whatever it is.
Brian Kernighan said:
Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.

In this case if you don't understand the code, you are obviously not going to be able to debug it.
Spend some time familiarizing yourself with the kernel, it's the only way to learn.

We just don't have the time to spoonfeed you. We are no tech support nor we have to provide you with support, the shame is that you refuse to actually learn something and just want to compile that damn kernel no matter the cost. It takes like five minutes to someone with enough skill to compile a kernel (it's just running a command).
The sooner you understand that this is out of your league and start with the basics, the better.
It's your choice to take this as advice or as a rant.

If you are an up and coming developer (I am assuming) then Github or the best place to start would be from lineage os website and their guide "how to build for your device".
And ofc you would need all possible help from our lead device developers like Shivam Kumar Jha and Sagar for the device trees, kernel source codes and what not!! I have no clue.
The base is already compiled from AOSP by the respective main contributors rather head developers. You have to take the source code and tweak it/compile it (ofc not easy) for our device.
You asked the question to explain android customisation in general!!! Well, if you don't know that, then unless you are on NZT-48 or a really genius programmer, I doubt you can do it. (Also great if you prove me wrong here). Don't mean to discourage you.
Wouldn't we do it all for ourselves??!!!!!
For Android customization - the basics would be to root and go tweaking, fiddling and modding around on the stock rom first. Lots of amazing stuff already. (Why to reinvent the wheel!)
Then depends on your requirements.
Good luck.

And ofc you would need all possible help from our lead device developers like Shivam Kumar Jha and Sagar for the device trees, kernel source codes and what not!! I have no clue.
The base is already compiled from AOSP by the respective main contributors rather head developers. You have to take the source code and tweak it/compile it (ofc not easy) for our device.
You asked the question to explain android customisation in general!!! Well, if you don't know that, then unless you are on NZT-48 or a really genius programmer, I doubt you can do it. (Also great if you prove me wrong here). Don't mean to discourage you.
Wouldn't we do it all for ourselves??!!!!!
For Android customization - the basics would be to root and go tweaking, fiddling and modding around on the stock rom first. Lots of amazing stuff already. (Why to reinvent the wheel!)
Then depends on your requirements.
Good luck.

A real thank you.
Have already started the learning process.
Hope to come up with a ROM soon.

Oh that's great mate!
Are you in computer science?
Or what programming languages do you know?

Good stuff!!
Attaboy:good:

I am trying the same thing myself using the lineageOS 15.1 branch.
I am using the directions provided in the lineageOS Wiki for the X00TD device (can't post a link because i am a newbie).
The instructions are clear enough but I am having specific problems with the brunch command - specific errors come up for missing files.
Is this the right place to start posting specific technical questions?
