30/Jun r1 (JFB) - MoDaCo Custom ROM for Samsung Galaxy S with Online Kitchen

I'm pleased to present my MoDaCo Custom ROM for the Samsung Galaxy S! READ THIS WHOLE POST BEFORE YOU START! No, really, it contains everything you need to know. wink.gif
This ROM is the 'starting point' for my Galaxy S custom ROMs.
About MoDaCo Custom ROMs
MoDaCo Custom ROMs are based on official ROMs - either shipping or leaked. A MCR release is designed to feel as far as possible like a stock ROM, with optimisations, tweaks and complimentary additions that enhance the user experience. The aim of a MCR is to be ultra reliable for use on an everyday device.
Requirements
In order to use this ROM on your device, YOU MUST ALREADY BE RUNNING THE JFB ROM FROM HERE. Do NOT use this ROM with any other base, unpredictable things will happen, the most likely being you'll have to reflash your device via Odin.
Features Included
* Based on the JFB release
* Rooted with Superuser 2.1 by ChainsDD
* Built with the MCR build process which reduces the size and boosts the speed of the ROM
* busybox with Droid Explorer support
* Updated Google Maps
* MCR version displayed in 'About' screen
* Optional Google Voice Search
* Optional Google Voice Dialer
* Optional Fancy Widget
* Optional Beebplayer
* Optional baked in Wavesecure via the online kitchen (installed to system partition for maximum security)
Changelog
Please see 2 posts below this one for the changes in each release.
Installation
To install this ROM:
* Ensure you have the JFB ROM installed (linked above)
* Download the zip file of your choice from the links below (or the online kitchen) and copy to your SD card named 'update.zip'
* Restart your device in recovery mode by running 'adb reboot recovery' (download adb if you do not have it already, use adb-windows, adb-mac or adb-linux as appropriate)
* Select the option to apply an update zip, and select the zip file you copied to your memory card
Upgrading
No wipe is explicitly required in order to use this ROM, however if you do encounter issues of any kind, it is recommended that you wipe your device and reproduce the issue before raising it here.
Downloads
This ROM is currently only available in the online kitchen - prebakes to follow.
Thanks
It's impossible to mention everyone who contributes to the Android community by name, but to everyone out there who does great work and shares it with us all - you have my gratitude and respect.
And finally...
If you would like to show your appreciation for the ROM, please consider supporting MoDaCo by signing up for a MoDaCo Ad Free or MoDaCo Plus account, both of which also give you early access to Beta ROM releases and access to the the online kitchens.
Enjoy!

Does this ROM fix the ram issue so that all 512MB of ram is utilized?
Congrats on being the first custom rom here.

Congratulations! I don't have a phone yet but I am very pleased to see a custom rom already!

woohoo custom ROMs already. Guess I'll be getting myself the phone after all.

umm.. but in another thread people where saying that it wasn't gonna be possible because samsung encrypt their drivers etc. so this mean they did release they drivers? and there is gonna be alot of custom rooms for galaxy gravity?

No I said it would be near impossible to get roms from other sources like Sense roms or Froyo on because of the driver issue. I never said you would never see custom roms. The only roms you are going to see are one's based off of Samsungs release.

Hold on, hold on. So even though Samsung released the Galaxy S' driver source code to the public, it's going to be "near impossible" to port Sense and FroYo to the phone? I may be ignorant but I'll just ask with ignorance, how do you figure?

Download the source code..... ok now open it and go to GalaxyS_Kernel.tar.gz. Now in there just enter the first folder then go to modules. Go to Dpram. Open up any of those files in notepad. You should see written non-compiled code right? That is fine now go back to the module folders and go to S3cbc. Now open up s3cbc_module.o. Does that look like non-compiled code? No it doesn't. It's either already compiled or encrypted. That's what I mean

Quick question, does that mean any custom rom that is release will be based off the official rom they release which has Touchwiz backed in? If so, does that rule out a plain vanilla android rom for this device? Thanks for your help and appreciate the knowledge.

No it doesn't rule out plain vanilla android rom. Yes they will all be based on Samsung but rom makers can take out all the touchwiz garbage and throw in another launcher like adw or Launcherpro.

That's what I wanted to hear. Thanks for the help. Now if I only could decide if I should keep the Nexus One or purchase this phone..... Decisions, Decisions.

How lame. Have other handsets had similar problems?

what are talking about .o files and unix compiled modules same on all versions of unix. o stands for object module.

So they can easily be decompiled? If it's source code why is it already compiled?

dont go too deep into specific things that we may not even need (we are not coders here) but the source code for basic hardware that we need to get things going are already there.. things like camera, wlan, etc. btw, do u know what s3cbc is for?

What about s3clcd? Here is a little copy and paste of some of the garble that was in the compiled file
screen width=%d height=%d va=0x%x pa=0x%x
I would go out on a limb and say those are video drivers. The one's that have been encrypted on all other samsung phones.
Also in s3cbc there is some code at the bottom
PVRSRV_PIXEL_FORMAT_YUY2 PVRSRV_ERROR_FIFO_SPACE char ui32ByteStride psDevInfo PVRSRV_PIXEL_FORMAT_PAL1 PVRSRV_PIXEL_FORMAT_PAL2 pfnOpenBCDevic
If you don't know the Galaxy's gpu is PowerVR SGX540 and YUY2 is a colol format for video screens
http://www.fourcc.org/yuv.php#YUY2 and Pal is of course a European video standard.

they are not encrypted, they are object codes in machine language for arm.. and why we need that again for custom roms?

Wanted to test modaco ROM but they are not free.. Any kind souls upload and share ?

well feedback on the R1 rom its clean and smooth, worked even better when i did the stall tweak posted here

How much free ram have you got? Considering flashing and rooting, but not sure if it's worth it right now. Meh 10£ isn't that much think I'm gonna give it a try.
EDIT: Just flashed, but now I don't have root access(says access denied when I try to access the /data/data folder). Thought this included the rooted PDA file or do I have to flash that again with odin?
EDIT2: Scratch that I forgot to press the allow-button on my phone after sending the Super-user request..

SenseUI and MotoBlur on Galaxy S

I got myself a Galaxy S to play with now, and so far the good part is the nice screen...
ive done some porting to motorola milestone which i will start looking into on this phone...
As i understand Kernel can be customized and we can pretty easily install mods using update.zip ?
is updating ramdisk "easy"? if you can handle linux quite well? anyone with instructions on building the initrd image?
secondly building an image? should it be tar'd using odin? or using update.zip?
problems on milestone has been "usb" steeling battery as the native support on htc is different so handling it required a scripting workaround..
with senseui the biggest problem will be porting Bluetooth as it is very different from standard google practice...
anyways i hope to be able to contribute with a SenseUI and MotoBlur port to SGS soon, when i get time to research handling on this model.

i'd really like to help you, but i'm not able... this morning i studied some tutorial such as http://pdk.android.com http://android.git.kernel.org http://d.android.com, but i'm new with linux and i can't understand anything... however i was asking myself the same questions...

Well, IDK if this easy, but manageable. Both odin (easier) and update.zip (more stable) options available.

Samsung is using a zImage. Compressed Kernel + Initramfs.
Since for 2.2 is no Sourcecode available till now, it's very hard to modify anything.
2.1 Source is available at opensource.samsung.com.
You can pack the zImage with tar under linux and flash with odin or you can flash the Image directly using redbend_ua (OTA Update) through an update.zip.

thanks , very usefull.. so the .md5 extension on odin files are related to?
anyways i have made zImage for other platforms so changing the ramfs should be straight forward...

Finally a person who knows their stuff is attempting at a sense ui port.
Hope you succeed

I really hope you succeed - I have time but no knowledge - if you need help pm me

thanks, im primarily persuing this as a personal challenge, but of course if ppl likes my work its great.
one note is, as written earlier, more experienced guys will be required to finish the bluetooth adaption, its alot more complex than the remaining parts.
and im told even on older htc phones it was hard to port drivers for bt.
my 2.1 sense mod on milestone was ok, except milestone only had 256MB, which resulted in many reloads of senseui.. here i think we can stabilize, even with a modified kernel to add swap if needed (if the 512MB utilization becomes a problem)

I would be very interested in a Desire HD rom for the SGS .
If it is completely functional for all the functions I use (I use no Bluetooth for example), I would be willing to donate too.

It's on the Freenode IRC servers. There's a bunch of talented developers working on improvements for the SGS there, so be sure to drop by.

Gingerbread Kernel Source Code Available; Homebrew Ports Coming?

Kernel Source for Google Nexus S Released
December 15, 2010 By: ElCondor
Android development for the Google Nexus S has now begun. The kernel source – originally made available upon the official phone release – has already been released by Brian Swetland, an Android kernel developer. This source code can be further investigated and explored by developers. Ultimately, this will lead to achieving development milestones much earlier than usual. One example is to root the phone just a few hours or days after it gets released.

Thank you Brian !
XDA member supercurio created a thread in the Nexus S forums. Make sure to check it out to follow the discussion, or continue directly to the developer kernel site.

yeah.. it's out:

Probably its just a matter of mili seconds before one pops up Cant wait >.<

Long like more than half a day? Lol.

Don't you need the source for the rest of the OS as well to build a full system?

The source is available now.

root anyway the custom roms are far superior

Theres a test build of Gingerbread in the oxygen thread

Tempted, even if I just had a rooted stock and remove some of the junk that is in the rom's...

If you're happy with the stock ROM, don't bother. You'll end up flashing ROMs all the time, always trying the newest or different ones - which is fun for sure, but not really necessary and often quite frustrating.

Can't wait to boot 2.3 on my Desire!

It's just a themed version I think.

emulating gn rom and kernel

Hey all.
I recently compiled android 4.0.3 AOSP for galaxy nexus as was explained in the topic at general discussion.
after a few days of issues, all went fine and i got myself a zip ota package file.
Now, as a developer, i wish to change the rom and the kernel, and debug/emulate it.
trying to type "emulator" didn't help and it suggested i would type "vemulator"
I got and installed vemulator but it asked me for a bootable image. (which one?)
Is there any way i could do this properly?
about the kernel development, i read some info and i separately got the kernel through a git repo. its alright but then again - how can i emulate it?
I do not wishing to risk my device is such early stage.
thanks.

You could try the android sdk.
Sent from my Galaxy Nexus using xda premium

further details please?
Until now i only used android sdk on windows.. so i have no knowledge of this under ubuntu.

I dont understand what you mean by emulating the kernel. I dont think that is possible as the kernel is so tightly tied to the hardware that it has to be loaded to the phone for testing. At least thats how i tested kernels. I make code changes, compile, and flash to device. When the code didnt work i had to flash old kernel or restore nand backup, then try again with code fixes. Repeat hundreds of times. Thats how i did it.

Now, about emulating the rom.. i understand it IS possible. which steps do i have to take in order to do that after i compiled the source?

The sources are buildable for multiple devices. Once build for one device it only runs on that device. Building for Galaxy Nexus (maguro) means no emulation but only running on real hardware.
If you want to build an image for the emulator you need to build the emulator configuration (e.g. full-eng). That will only run on the emulator not on a google nexus.
See http://source.android.com/source/building.html for possible configurations and how to run the emulator.

How do I start developing ROMs?

I've tried out almost every ROM I could find for the VZW Galaxy Nexus. They all have their own pros, but none of them were really perfect for me.
I already know Java, so I know that should help me a lot. But I do have some general questions.
My main questions is, do I compile from source? Or do I use something like JRO03L? What exactly is JRO03L? I noticed a lot of ROMs were based off either AOSP or JRO03L, or some other ROM.
When people say their ROM is based of AOSP, does that mean they edited the source code directly?
What about drivers and stuff? Do phones even have those? How do I get them for my phone?
What percentage of ROM editing is done through source code modifying and what percentage is through Cooking?
Sorry for all the questions, I'm just kinda confused.

compile from source needs linux (mac osx only builds master branch);
aosp = android open source project
JRO03L, JRO03R: release tags. they mark a certain landmark in android development, normally leads to/are (pratically) the same as ota's.
yes, aosp-based roms edit source then build. why would we cook when we can build? makes no sense on a aosp supported device like ours.
on linux, just install android-sdk (includes fastboot and adb) and add it to your $PATH, and create udev rules for android devices (most distros provide this as a package). no need for drivers on linux.

Thanks for the links
And when I mentioned drivers, I meant for the phone hardware. Like, does android just magically work on all phones? or do some phones need something extra to work with AOSP?
Now, after I set up Ubuntu with the guides above, are there any guides to the basics of source editing? Like what do I need to do to install busybox? root android? theme?
I googled on how android 'worked' , so i can get a better understanding on how it operates, but all the results were pretty vague.

obviously not, that's why i said "aosp-supported devices". devices that aren't aosp supported, need the same things we need, except in their case there's the matter of proprietary frameworks and drivers (called binaries), which we have available almost from the start.

sure, guides @github or at any other repo. there's no better guide than being able to read source code and how the masters do it.

it tells you where it is when it finishes building..
