Information regarding creation of a custom ROM

Hey, new to the forums, recently purchased a GSM Hero.
I have done some development for free software (think freedom, not price) projects, and have become accustomed to git repositories and structured development.
Upon entering the world of custom Android ROMs (at least Hero ROMs) I have been sorely disappointed with the development practices going on, releases on file sharing sites and the like.
On top of this, none of the ROMs available suit my needs.
This is all fine, as I'm not developing those ROMs.
I have decided that I need to start working on my own custom ROM, however guides and documentation regarding this process are in short supply.
It would be much appreciated if someone could link me to some guides to starting my own custom ROM.
I intend it to be a light vanilla ROM, with none of the bloat that seems to perpetuate other ROMs, I'm aware other such ROMs do exist, however none of them support all features, and even those that claim to do so, often require me to FC

Have you tried this one ? >[2.1] aychteesees-vanilla-cupcake< NOT the [3.0.1]verison ..this is still @dev
http://android.modaco.com/content/h...96/3-0-1-aychteesees-vanilla-cupcake-rom-gsm/
Give it a try [2.1] ! and tell us how it went ...

Yeah I tried that one, it claims to have full functionality, however I frequently had to FC various applications.
I'm downloading 3.0.1 as we speak, however I'd still like some resources on making my own ROM.

I'm interested on this documentation too....thanks

That's weird , I have used almost everything ( apps ) with that ROM [2.1] ... and never get FC's
Did you flashed from Zero .. I mean with all he possible wiping . inlcuding SD ext partition wipe
???
That is a MUST ..!

Before this gets too off-topic, I too would like to concur with what OP is saying. I'd love some info on where to begin with custom ROMs, and I think it would be great if we could create a community repo for code for a custom ROM.
This leads me to another question: all these custom ROMs that we see available for download -- are they free/open source? Like, do they have source code available? I certainly don't think they do, but if they don't, then aren't they violating the terms of the GPL by not providing source code?

There's Paul's (modaco) online kitchen, but if you want to compile by yourself, there's a plethora of gits on github (cyanogen, lokx, kiall to mention just a few).

Good question. Yeah it would be nice if there was a 'Cooking Class' thread on this forum like in some of the other forums. There is a decent tutorial however at HTCpedia.com under the HTC Hero ROM Development section, it's in the stickies there. However, I still have questions and that forum is not visited as much as xda.

As a start, I would read that thread I just linked above. Once you can dump the contents inside the system.img and then combine it with the boot.img to build an update.zip, then you are already halfway there - that's actually fairly easy. But knowing how to add custom kernels to the update.zip, making the custom ROM rooted, etc. are all stuff that I'm still working on. There's supposed to be a lot of info in the Dream/Magic forums, so I'll keep reading.
Android is still fairly new and very few people know how to use Linux, thus there's less support and less interest in wanting to cook for one's own Android device.
BTW, that thread I linked above is also found here.. Doh!

Thanks for the link, a good read.
Anyone know what the process is for using a custom kernel? There are a few things I'l like to enable that aren't in the HTC kernel (like FUSE).

If I eventually manage to find out I will post it here. My most important concern is making a rooted ROM from those shipped ROMs, as some people have been doing here.

[App] 2BOrange - Install any kernel (Voodoo, SpeedMode, Infusion...) without computer

____________________________________

____________________________________​
Hi everybody,
I have made a free application to install any kernel on your SGS very easily.
The idea is that there is a website where kernel are uploaded with a script and an application to:
- search
- download
- install it on your phone.
The application and the website are not limited to install kernell but I think it is a good way to try it.It can execute any script in the android shell.
So I have made some script for some kernel, there are so much that I have not the time to make one for each of them.
To make a script is very easy, I have attached an example of one I have uploaded on the website. If you need to attach a file, put it in a zip and upload both (the script and the zip) through the upload form on the website,
The address of the website is:
http://www.2borange.com/
A general thread on XDA (not dedicated to kernel on SGS) about the application:
http://forum.xda-developers.com/showthread.php?p=14875954#post14875954
You need to create an account to upload but it is not mandatory to just search, download and install a kernel.
Please keep me informed if everything work or not. I have only test it on my phone.
For the author of the kernels: I am sorry to have not yet informed you of the sharing of your great work, I will do it for sure when I will have done enough test to offer you an interesting way to share your work.
For the user: if you have time, don't hesitate to upload some scripts, it is free and easy to do...
Thank you for everything,
Michael
LIST OF KERNEL AVAILABLE AS OF JUNE, 27:

This allows you to actually find a kernel, download it and flash it as well. The Kernel Flasher is just for kernels already on your sd card.

Thank you for your message.
I did not know about this application. I have read the description and I can tell you the purpose of mine is totally different.
I have understood that Nedar application is to install a Kernel that you have already downloaded and copy on your SDCARD.
The purpose of my application is to download automatically a script and a zip file, and execute the script.
So there are 2 main differences between these two applications:
- my application get files you need directly from the cloud (Internet), so it is like a deposit of files
- my application is not limited to kernel installation, it is just a usefull example to show people how it works, but it can do more, really lot more tasks.
However, because the application of Nedar is dedicated to one particular task, it has option I have not yet implemented in mine. By example, I have not yet construct a script to backup the kernel in an update.zip file, which could be very usefull.
So they are really very different. I hope I will be able to construct more script, but may be the biggest difference with any dedicated application is that anyone can participate to my project without any knowledge in Java programation.
You just have to know a little bit about shell to be able to share your work with others.
THAT IS THE REAL PURPOSE OF THIS APPLICATION : SHARING!

Amazing concept!
Thumbs up for the foresight for such a nice project. If enough effort is put I can see in next couple of months, the whole, ROM, Kernel, Modem flashing automated.
Right from finding the correct software till installing them and may be some debugging and fault finding as well!
Will definitely donate in case the project takes off the way it should!
Great work Snoopy!

Loving the concept of this!
As omzworld was saying, if this grew into a script that could automatically install your ROM/kernel/modem etc. that would be awesome, especially for people who are new to flashing.
Now, here's another suggestion that may or may not have been thought about already..
Is there any way to make the app look at your phone and use that as a basis for roms, kernels etc. ? If that was possible, anyone and everyone would be using your app to flash because they would know that bricking their phones would be almost impossible.

Thank you for your interest.
The thing I need now is not money, donation,etc... but report of test and ideas of improvment.
By the way, I only have a samsung phone, and I am wondering if there are possibilities to install kernel in other phone only by using the shell, have you an idea ?
Second question: have you an idea how to proceed to install an entire ROM through the shell ? I suppose the phone has to be rebooted before installation begin and lauche in a recovery mode, but how to make it automatic like in ROM Manager?
Thank you for your help!

I have already included a kind of filter based on brand, model of phone and firmware version plus sdk version, do you think it could be more precise?

Fixed script on server, should work on every phone now

Hey snoopy33, why do you have not yet updated this page?

[wip][rom][aosp] ns2

Change of plans, hopefully with the help of anyone who is willing I'd like to compile an aosp build for the Sprint GS2 from source instead of trying to hack a port together, as suggested in this thread and other places, it just feels like it will be a lot more of a fruitful experience for all involved and have a better end result.
(a big thank you to everyone who so far have been super encouraging and friendly with noob questions, it's much appreciated!, I hope that if you wanted to help with the port you'll help with this build as well!)
This is a WIP. Starting out with Samsung's open source platform and kernel instructions on how to build from aosp and I'll take it from there.
I've setup some repos to get this all started in one place:
Samsung SPH-D710 platform source - https://github.com/thefredelement/sph-d710_platform_source
Samsung SPH-D710 kernel source - https://github.com/thefredelement/sph-d710_kernel_source
Team Hacksburg kernel source - https://github.com/thefredelement/android_kernel_samsung_c1spr
Stock kernel initramfs (thanks buddy323!) - https://github.com/thefredelement/stock-initramfs-eg30-epic-4g-touch
https://github.com/thefredelement/Samsung-Galaxy-S2-Sprint-Epic-4G-Touch-AOSP-Build - will be where the build will live after I push over Samsung's platform make and upload it!
--- old stuff that will make your head spin ---
If anyone wants to continue working on this, feel free.
This is my attempt to get get a pure aosp build of android 2.3.5 for the Sprint Galaxy S2. I've never done anything like this before and it's mostly hacked together pieces of two different ROMs. I guess you can call this a "learning" experience.
THIS ROM JUST BOOTS AND NOTHING ELSE REALLY WORKS, THIS IS A WORK IN PROGRESS AND I POSTED IT HERE TO SEE IF ANYONE CAN HELP, THIS IS NOT A DAILY DRIVER, NOT EVEN CLOSE.
THIS HAS ONLY BEEN RUN ON MY PHONE, EVERYTHING IS FINE ON MY PHONE AND I CAN RESTORE A NANDROID BACK TO STOCK AND EVERYTHING STILL WORKS FINE BUT I MAKE NO GUARANTEES FOR YOUR PHONE. IF YOU DO NOT KNOW WHAT YOU'RE DOING I WOULD STOP READING NOW
This rom is based on AdamG's devnull-test aosp rom for the Euro Galaxy S2. (post: http://forum.xda-developers.com/showthread.php?t=1183063)
Credit must be given to AdamG for his rom in the first place, bubby323 for his help on IRC and kpkimmel at ACS for the Gerbal V1 beta ROM (post: http://www.forums.acsyndicate.net/showthread.php/2734-ROM-Gerbal-v1-beta-ROM) which I used for guidance for the build.prop and updater script.
I am not trying to steal anyone's work or take credit for anything, I really just want a pure AOSP rom for the Sprint GS2 and would love anyone's help as far as guidance, code, a guide I haven't found, anything would be great, thanks.
Known bugs:
- No radios
- No Wifi
- When wifi is on (or trying to turn on) the screen turns on/off as if a process is restarting
- Orientation sensor is out of whack (disable auto rotate so it doesn't drive you crazy)
- Home button & search button do not work
- Something FCs real fast on first boot but android setup starts
- Distortion on the touch screen occasionally
Known positives:
- No real FCs
- I added the Nexus S boot animation
- Calculator, gallery, etc. all work fine
What I've done so far:
Based on buddy323's advice in IRC, I've brought over vendor, firmware, wifi, vold, egl and hw from the Gerbal v1 rom to the devnull rom.
I used the wipe partition section of the Gerbal update script and then the symlinks/permissions from the devnull script (I removed the kernel installation as this rom doesn't come with a kernel). My approach has been to go through as much as I can on devnull and change out anything that's platform specific to the sph-d710.
I'm sure there's a bunch of noob happening in this rom and I'd appreciate it if you can call me out on it and tell me where to look to make it right.
Installation:
Install via clockworkmod, this will wipe /system /data so I'd erase your user data before flashing.
I've been booting this with the stock kernel.
Link: you don't want this...

Reserved for changelog, when hopefully it gets that far

Awesome to see a project like this, good luck in the port!

Constructive criticism would be for me to point out you must not have read the OP because it clearly said nothing works because we don't have a aosp kernel yet but you are just rude.

You are under no obligation to install anything posted on XDA. If it doesn't work, report. If you don't like it, don't use it. Help, don't hinder. If you have nothing to contribute, then sit down, shut up and wait for someone to do it and allow you to participate. It's that simple folks.
Now keep this on topic or infractions and/or mandatory vacations will be handed out.

I would highly recommend you get to grips with the aosp source and learn to build them for the device instead of cobbling a mix of aosp and stock Samsung roms together. You will also need an aosp compatible kernel and stock kernel is not. There is a list of patches to the aosp kernel in the SGS2 section and on team hacksung's github. Good luck.

it was one of the cyanogen devs that got a galaxy2 & they have nightlies for the gs2 now.... It should not be hard to get it ported over

[Q]creating my own rom?

Hi guys- I have seen a website or page on how to build your own rom.
how difficult is it on 1 to 10?- 10 being very difficult.
what tools do I need?
many thanks

Well it depends how you create the rom and what type of ROM you are creating.
If you plan to simply take an already made rom.zip, make a few little modifications, and zip it back up...it obviously isn't very hard, and likewise its not very satisfying.
If you want to compile a rom from source, then its a bit harder than the process above. To be more specific let's first talk about android versions that are officially supported by the desire: froyo, and gingerbread. Compiling roms based on those honestly isn't that hard. You just need some basic Linux/terminal knowledge. The device and kernel source is actually meant to work by default so you don't need to make any further adjustments. It as simple as opening terminal, downloading the source, and running a build command. Give it an hour (more or less depending on how food your PC is) and you should have a freshly made ROM that you built from source. Yay...some satisfaction.
The hardest thing in my opinion (I've tried all three of these) is compiling a rom based on an android version that isn't officially supported by the desire. (Ice cream sandwich or jellybean). With roms based on these android versions you will have to scour to internet for a working device, vendor and kernel tree. (Hint, hint: WoH and evervolv/nikez). Even once you get the right device tree it probably won't work. You will have to make further adjustments, and even then I'm sure you will be bombarded with build errors. But eventually once you get it to compile successfully....most satisfying thing ever
So yea thats my answer. Keep in mind that I've tried (and eventually succeeded) with all three of the above, and that I've got quite limited programming knowledge. (2 high school comp sci courses, where I learned some java.)

Sound very complicated
I am a webdesigner but have no knowledge of developing.
Wanted to try and build a really good rom to make the desire a really good phone for photography.
I have on my phone your rom and RSK supersense 3.5 rom running - coz I like the camera
and I would like to make a rom to turn it into a photography rom for my phone.
any advice??

Obviously you have to use a desire device tree.

will this work on geeb?? ill defintely test if so

Extract the build.prop. It will tell you cause I really don't know lol. All I really know is I added the LS970 dependencies to my repo, did the UnityKernel mod and built it. So you tell me cause I'm not at my PC

I am fairly certain it will run, but you might not have access to SD card or camera. If not, find out if there is a GEE/b kernel you can flash afterwards or if the OP can create a GEE/b kernel since it looks like it has a new kernel, aside from any other currently available. I know I've never seen UnityMod kernel anywhere.
To the OP, if you ask any of the other kernel devs what changes they made to produce a Gee/b kernel of the same settings I am sure they would provide some advice.
EDIT: some changes may be necessary in the build.prop as well to allow access to GSM.
EDIT: Don't really want to be part of this thread anymore and I haven't said anything useful

Ok. I am the OP BTW. Founder/Creator.
The UnityKernel cannot be found. It's the major unique feature of UnityROM-2. How it is done is quite simple. To me. But I remember when I had this phone. How badly it needs a good stable ROM. Just like jewel did till I did this.
So trying to do y'all a favor lol. The best ROM for Evo LTE now coming to the next Sprint "Problem Device".

I saw you were the OP, that's why I quoted you too LOL. No worries. Thank you for building this ROM. I haven't tested it yet because I am working on getting the G3 port to work on our Sprint OG. But I am happy to check it out. I just wanted to let you know that you can build the geeb kernel too. I don't think it takes much, I think only adding or switching a branch for your build.
Also, if you created this ROM and built from sources, you might want to think about having this thread moved to Original Development instead of Development. This one is more for ports and changes to an existing rom in order for it to work on our phone. The new Roms and creations should go in the Original Development.

You did a great job, it works fine. I think you should continue to work on perfection of Rom. As far as I understand, you need to go to another forum thread(Optimus G Original Android Development). When using the camera - got two crashes . everything else works perfectly, quickly and smoothly! Antutu received 20673 balls without my optimization. Thank you for a wonderful job. I know little about it, but it seems to me that all is well. This gproj or aosp based? You use the new driver for the camera? Excuse me for my english.

Well thanks for the feedback. I'll run 2.7.0 for LS970 now. Tons of new things added for the build and kernel

Well if I knew what I need for geeb I would gladly make it for you guys. I just grabbed the stuff listed in CMs LS970 device cm.dependencies file.
I can always add more or a new defconfig file to have it look at while building. Either way will work

If I can get my net to cooperate, I have 2.7.0 ready and attempting to upload.
Y'all ready for this?

UnityROM-2 v.2.7.0 has arrived and is now posted
Fully featured now with all my normal modifications.
Yes Google apps are built-in... technically...
The separated internal directories make it OK to do this legally.
Enjoy everyone

Looks like you're flashing for the wrong device, or wrong recovery.
