I've been getting my feet wet in cooking, mostly thanks to Alex's tutorials and I'm running in to a weird issue. Apps that I have not selected in Package Tools 2.7 are being installed with my ROM. According to the FAQ/QA in the tutorial, Alex says I should just remove those that show up from the packages directory.
My question is why are they showing up? Does anyone know. I assume it's a precondition of either the rom or whatever file is used to make the rom.
Which brings me to the next question, I can't seem to find a good set of threads that describe how the process works other than Axel's tutorial. I'm assuming there is a manifest somewhere that the package tools builds then passes to the cooker. Can someone point me to or outline the actuals steps?
Thanks.
I hate to make a thread on this but would like to get started soon with learning how to root roms and add the kernel for multitouch and tethering. This is more for my personal use since I just want a stock rom with all the root benefits like jf use to and theses are the questions I have.
1. Will I have to take the update.zip file and extract everything and modify it then resign and I'm done?
2. I read some info on adding busybox and root which seem easy but when I run the chmod command and such everything will be through adb and the files will be on my pc so do I just make sure its all in the right directory and file path?
3. Where are the wallpapers stored in builds along with animations I will be looking into the framwork/framework-res.apk later but still curious
4. The modified kernel for tethering and multitouch is located where along with the market.db file?
5. What is meta.inf and how easy is it to make the cpu 528mhz standard also not sure what BFS and ASOP are haven't been keeping up.
P.S. I would really appreciate some help on this and I don't mind reading if this information is somewhere else so please provide a link and as always gotta show love to those who started this like JF, Hakuro, Cyanogen, Drizzy, and many more like daproy and kornub did a lot of helping.
I hate to make a thread on this

You mean you hate starting threads in the correct place?
Thats a fine line here. Although it is a question, it is specifically a development question. Its not a which rom do i choose?
Although android is "open source" these people dont give a **** about people trying to learn how to develop. They will pull the google line or something.
yeah me 2
Trying 2 learn
Im a noob, so I can only answer two of thosew questions
1. Anytime you modify your update.zip you will have to resign before trying to flash it onyour device.
5b. BFS: Brain **** (simple) Scheduler, something to do with the priority of running proccesses or something http://en.wikipedia.org/wiki/Brain_Fuck_Scheduler. AOSP stands for Android Open Software Project, which i believe is just googles standard rom really (but I may be wrong)
I recommend you try out this rom though, kind of like JF but for Donut http://forum.xda-developers.com/showthread.php?t=538456
Very Sorry, double post
Thanks! I'm actually using that rom and its what has me so interested in this cause I hate having to flash another update.zip to get the full root benefits when JF just made everything available in one nice package but looks like I will just have to go through trial an error unless I get some more feedback cause switching between cyan 4.1.11.1 and JF1..51 is killing me and taking up space on my card.
With my little to no knowledge, replacing the boot.img and some files in system/bin with the ones provided in theofficial expansion pack should give you all that you need. With no extra apps.
yeah me 2
Yeah me too
This question is probably already asked, but I can't find a clear answer for it.
2nd thing is that I can`t see the forest for the trees anymore cause I'm quite an android noob.
I wan't to try to build a custom rom, but how do I get started?
As far as I know there are 2 ways:
1) Take an existing rom (either stock or custom) and mod it.
2) Start from scratch.
The 2nd method is of course the most interesting (but probably also the hardest) method.
So say we take that method.
First of all I think android basically consists of 2 parts, being the kernel + all the rest.
You can take a kernel from a working rom, which may be moddified, but can you also build the original kernel from the source? For getting that to work on my device I'll probably need the drivers, but how? Extract it from the latest official rom? And how to add them?
Samsung (yes I have a samsung s5660 aka gio) also uses the rfs filesystem, would it be possible to use ext4 and does the kernel need to be adapted to that?
And how do you make the rom flashable for odin?
A lot of questions, I know, but isn't there a step to step guid for doing this kind of things?
Thanks
yes, its possible to create an odin flashable rom with ext4 as default filesystem. and yes, obviously the kernel need to support ext4.
read this thread, particularly the first post.

As lately some people are asking me about ROM porting I decided to create this new thread where we can share knowledge about this hard task.
Please note this is a Dev talk thread, so DON'T ASK about fixing a particular ROM problem here. Also don't ask questions like "My phone is bricked! please help!". This IS NOT the appropriate place for it. There are plenty of other threads to help you out.
Also note that this is not a step by step guide (and not a guide at all), it's just a point where you can start from. Android is a very complex system and there are many things I don't know yet. So, research and hard work is what you need to learn it deeply. My first tip is Google really works. Don't be afraid to search
Ok, to the basics. Porting a ROM is no simple task. It requires advanced understanding of how android works and how it is organized. Previous Linux/Unix knowledge helps A LOT. As android is based on this O.S. there are many similarities between both. In fact many ppl consider android to be a kind of linux distro.
The very first task to port a ROM is finding a device which is compatible with your own. For example Defy/Milestone2. Then you are going to choose a ROM to port to your device.
As our devices (Milestone2) have a locked bootloader we now need to find a system image that have a compatible kernel with the ROM we are trying to port. This is mainly based on trial and test and takes a long time. You'll be ending flashing your phone several times with RSD Lite. You should learn how to use MotoAndroidDepacker and how to create a fixed SBF.
The basic procedure to try that:
1. Open original ROM update.zip and remove any files/commands that flashes boot/devtree/recovery/anything.
2. Install this new file on your phone via CW Recovery.
3. Boot into bootmenu and enable ADB so you can read logcat while phone boots.
4. Choose Boot/Normal. If your ROM uses 2nd-init you will need to place/edit/adapt bootscripts into bootmenu 2nd-init folder.
5. Check logcat for errors:
- If you're getting HAL errors you're going to need a new kernel;
- If you can start android without getting HAL errors but still getting errors and bootloop on android animation you should try to replace libs with appropriate original ones.
6. Once you are able to boot android you should test it's features to see what needs to be fixed.
This is what I have to say for now. The thread is now open for discussion.
At this week, motorola has just pushed the GB official update for Droid 2 and Droid 2 Global....
Can i try to port this new rom to milestone 2 and after a success boot, fix the radio..??
I was asking that, because some people has success on port CM7 to milestone 1, when it originally maked for droid 1...

It may be possible, but you'll have a hard time fixing the baseband.
You may have to mod the init.rc scripts and find the right radio binaries (rild is one of them) and drivers.
Ask those ms1 people for help, if they are still with the same phone...

I don't know if this will be relevant or not.
I wanted to know if to do any of this, having a Linux distro as OS a must or can I try my hands at it on a windows based machine. I mean I'm sure that a Linux distro will give certain advantages (as Android is based on UNIX/Linux) but can we get things to work a 100% on windows.
If yes, then will someone be kind enough to get give the list of all softwares etc. which will be required to do the job on Windows machine as well as a Linux machine.
I do know a few softwares but I'm not sure if I have an exhaustive list. I would like to learn and try and at least be able to modify in bits n pieces to begin with.
I apologize if this wasn't supposed to be asked in this thread.
The only thing i can get from SBF is a bunch of smg files.
But the only ones i can open are
preinstall.smg
CG39.smg
Is there a way to open/see the rest?
2)
Im trying to modify the CM7 rom, what boot does it use? 2nd-init or 2nd-boot?
i guess it is second-init. but not sure
thanks a lot for this !!!

SMG files are disk images of certain partitions of your flash memory.
You can only open CG39.smg and preinstall (CG66.smg) because they are the only images in ext3 format. The rest of images may be on ramdisk format or some proprietary format. For more details on partition codes take a look here:
http://and-developers.com/partitions:cdt
You may be able to open and see contents of other partitions but the only one that matters aside from system and preinstall is the boot partition (CG35.smg), which contains the init scripts we should mod in order to make they work with 2nd-init. Boot partition is in ramdrive format. More details here:
http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
http://elinux.org/Android_on_OMAP
It is easier to unpack boot image using Dsixda's Kitchen here:
http://forum.xda-developers.com/showthread.php?t=633246
Edit: To see what boot your CM7 uses just go inside /system/bootmenu/config and look for a file called default_bootmode.conf. That should be the boot method used. It's normally 2nd-init.

Don't worry, this is the right place
As for your question: yes you can work in windows if you like, but using at least a Linux VM is more productive. I don't have a full list of applications to give you, as different mods may require different tools, but I advice you to have at least:
- Notepad++ (essential for editing text files and keeping linux end-line format);
- dsixda's Android Kitchen (http://forum.xda-developers.com/showthread.php?t=633246)
- 7zip (or some other compress tool you like)
- Moded putty for ADB as working with windows command prompt really suck (http://forum.xda-developers.com/showthread.php?t=803225)
- Oracle Virtual Box (if you are going to use linux VM).

- Moded putty for ADB -- got it
- Oracle Virtual Box -- can't install Linux on my system as this is a work machine
dunno if I can do without the last option.

Oracle Virtual Box is an application that lets you run an operational system on a virtual machine, in other words, it doesn't install linux on your real computer. It's a very useful tool that I use everyday. Google for it and learn a bit, you won't be disappointed. About kitchen: the link I provided was download + guide. Read it again. If necessary read the full thread.

I know a bit about virtual box but as I said I'm not allowed to have softwares not approved by the IT team to be present on the system. Though I can get away with small things like notepad++ and 7-zip, having virtual box on my system may raise some eye brows.
I'm trying to arrange an alternative system.
Me neither. I must do almost everything at home, and at this very moment I simply don't have any free time. I'm afraid you're not going to see me here very often anymore (maybe in a few months? a year? well, it might be a bit too late for milestone2...)
hi. Have a question, I want to remove baseband from a flashable zip (lets say, CM7 from Tezet) , is it posible? I dont know where to look for it (baseband). Thanks!!
Baseband is located in \system\etc\motorola\bp_nvm_default\
But don't remove it, just replace it with files from ROM, which have baseband you want.

Hi All,
Just a quick question. I have ported Paranoid Android 2.10 to MS2 but the problem I am facing is that Reboot goes through Bootmenu and I have to choose reboot from Bootmenu again.
Any inputs?
Thanks in advance

I meant to get to it last night, but I was tired after work and fell asleep watch tv. Eventually, later tonight, I'll be uploading PA for MS2. Check my Defy PA thread in 12-14 hours cause I'm about to go to work and I'm not gonna feel like making a MS2 PA thread or updating my Bravo PA thread -- but the Defy Thread is always up to date when I put out new roms.
Also, I'm looking to get either a Defy or MS2 -- I've heard that there's 3G issues with AT&T users (which I am) with the MS2 -- Apparently the MS2 has different 3G frequencies than AT&T. Are there any AT&T MS2 users who are knowledgeable about that? While I can deal with no 3G, edge only, calls only -- I need to make sure I can at least do that before I commit to something.
I'd rather have the MS2 because I want a hw keyboard and I don't have the $300+ to try and get a Photon Q LTE from eBay (and I don't have to change up my repos if I get a MS2). If anyone here knows of a phone that's AT&T compatible, Defy code compatible, and has a keyboard, please let me know.
Thanks.
//Normally I'd post the latter half in the Q&A section, but ya'll don't have one so I'm just gonna piggyback

Ok devs need some help here.
I am trying to port a rom to our Milestone 2...but it bootloops on rom animation.
I tried to logcat it but I don't think it gets as far as adb server to detect the device.and just keeps saying "waiting for device"...so I end up with no logcat to diagnose the problem.
I can logcat my current working rom but only after the phone boots....am i missing something here? please, help
Any help is very much appretiated.
Thanks a lot in advance
i need some help devs,
im a newbie and i tried to port custom aosp rom using tutorials i found on the internet,and of course here. i replaced all files and pack port rom in zip but unable to flash it,it says error executing updater binary in zip .......
im using leagoo elite with stock rom rooted and tried to port aosp 7.0 for another device but same specs except kernel (newer) in rom
i didnt managed to find tutorial how to port kernel so i just replaced boot.img,
and one little thing, rom i tried to port was packed to new.dat files,and i managed to unpack but cant repack it again
i read that if u flash via recovery only boot.img has to be in img file or correct me if iam wrong
please help me with this or with tutorials or guide me throu this,
im just a guy who wants latest android for his phone but there is no devs that work on this phone
if there is anyone who is willing to do this for me i can pm him links for download of everything he needs and i can make a donation if it works, cheers

You will need to find pre-built blobs for your device or extract them. If they do not work on newer Android versions you will need to hack them or find alternatives. Not everything is the same about the device, including the panel, camera etc... You will hopefully not need to edit the kernel for the blobs to work properly, but it's a lot more work than you think it is.

I found the phone with exact same specs procesor ram storage camera mp not sure about lenses but i dont find tha as important, only thing that is different is kernel version. Blobs are? I know its not easy but im trying to learn something. I found 101 guide for this but after reading all of that it just messes up in my head. I would like to find someone who can walk me through that step by step and share his knowledge

Blobs are pre-built drivers that do not have a source and thus cannot be built by CM themselves. You could try to compare all the drivers in system/libs on stock ROM of your device and CM of the other. There are tutorials on how to port CM to any device, try to search for such topics, they are very helpful.
