Original post:
Hello,
I am new to android but not to linux. I used to tweak my winmo phone rom.
I have backed up my device with nandroid. I just need some explanations:
- why isn't the radio extracted?
- how can I "extract" does .img files to modify and then rebuild them?
I found some informations of what the .img files contain here: ROM Partitions it should be the same for Hero
I have found some informations on how to push updates to the rom by looking at modaco updates. It seems quite simple to delete/copy files on the hero rom using an update-sript file. I am however curious about the RSA cert and if some files need to be signed.
Any information welcomed.
Regards

How to
Extract NAND image files
To extract .img files, I have found unyaffs from http://code.google.com/p/unyaffs/ I have compiled it under ubuntu 64 (attached). Unyaffs works on system.img but on no other .img file
To extract boot.img use attached extract-kernel.pl and extract-ramdisk.pl
# extract-kernel.pl boot.img
# extract-ramdisk.pl boot.img
Should work for recovery.img but haven't tried as custom recovery images on the forum are great.
Rebuild system.img
Seems you just need "to loopback mount an image on your linux box and format it with YAFFS".
But it is useless as because Hero's SPL does not allow flashing system.img directly. You should use an update.zip package for that. (read below)
Rebuild boot.img
After extracting your boot.img using attached extract-*.pl and tweaking it, in same folder run:
# mkbootfs boot.img-ramdisk | gzip > ramdisk-boot
# mkbootimg --kernel boot.img-kernel --ramdisk ramdisk-boot --cmdline "no_console_suspend=1 console=null" -o newBoot.img --base 0x19200000
Creating an update.zip package
Creating an update.zip package is quite easy in fact. For example, to add a (valid) test.apk package to your rom:
- create an empty folder <workdir>
- create folder structure for test.apk (<workdir>/system/app) and copy the test.apk
- create folder structure for update-script (<workdir>/META-INF/com/google/android)
- edit <workdir>/META-INF/com/google/android/update-script
- put in it:
Code:
show_progress 0.1 0
copy_dir PACKAGE:system SYSTEM:
set_perm_recursive 0 0 0755 0644 SYSTEM:app
show_progress 0.1 10
- compress the <workdir> content to zip (not the <workdir> folder itself)
Now you are going to sign the zip file. Download attached testsign.zip and copy it in your <SDK>/tools folder. Extract it here. It should create a sign subfolder with a testsign.jar file in it.
Then, from <workdir> folder, do:
java -classpath <SDK>/tools/sign/testsign.jar" testsign file.zip file-signed.zip
Ok, now your zip file is ready to be deployed using cyanogen recovery image.
To find more command to use in update-script, look at other's.
Modify .apk package
Seems it is easy to uncompress an .apk package (zip) an to modify files in it and then compress it. But after all: you must sign it like update.zip packages.
ODEX files
- What are those Odex files? Answer.
- How to get rid of them?
Odex files depend on framework they are made for. To deodex an odex file use that how to
Then you may create a classes.dex file by executing the smali program on the "out" folder. You then rename it to classes.dex and add it to the .apk.
- How to create them?
Use dexopt-wrapper on device.
Porting an other device's rom
Well, that part is easy
- extract the system.img
- extract boot.img
- replace boot.img-kernel with the one from your stock Hero rom one.
- rebuild boot.img
- build update.zip package (look someone's hero custom rom to see how to do it)
- sign and flash
It should run place and make calls but probably won't have Wifi, BT, trackball support. If you make those work: tell me, but I think we should wait to be able to compile a 2.6.29 kernel to have those.
Tools
Androsign script (linux)
I wrote that androsign script to quick sign zip files. Just put it in your <SDK>/tools folder, then chmod +x. If you have put the tools folder in your PATH, you can call it directly like this:
androsign /dev/folder1/folder2/update.zip (or any zip/apk file)
It will output an update-signed.zip (or app-signed.apk etc) in the same folder than original file was in.
Notes
Note1: thanks
Thanks to every guy that helped me found all that.
Note1: sharing
I searched for hours, so I am more than happy to share it to save someone's time. I am just disappointed than some people here do not have that spirit: I could have use those hours for development instead of research...
Note3: corrections
So, if you found anything incorrect, would like to supply more informations or want to correct my bad english: just PM me.

unpack and pack boot.img and recovery.img
First you need utilities such as mkbootfs and mkbootimg. maybe you can find them online (i can upload them later compiled for linux x86-64) but i suggest you download android source (http://source.android.com) and do a generic make. In this way you have these and other utilities(tools to pack system.img too, but if you haven't an engineering bootloader you can't flash it directly) in /out/host/... (it's better if you add this in your PATH)
To unpack and pack boot and recovery, read here:
http://forum.xda-developers.com/showthread.php?t=443994
or here:
http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
...or...
(I have attached extract-kernel and extract-ramdisk scripts from JF build environment) :
to unpack (boot.img or recovery.img, i'm writing the commands with boot.img):
Code:
extract-kernel boot.img
extract-ramdisk boot.img
at this point you have
boot.img-kernel
boot.img-ramdisk
to repack (boot.img or recovery.img):
For hero you need to specify the base address because it's different (0x19200000). For more information: http://forum.xda-developers.com/showthread.php?t=541522.
Code:
mkbootfs boot.img-ramdisk | gzip > ramdisk-boot
mkbootimg --kernel boot.img-kernel --ramdisk ramdisk-boot --cmdline "no_console_suspend=1 console=null" -o newBoot.img --base 0x19200000
Useful resources for android modding are the dream forums (most of the concepts/hacks works for hero too):
http://forum.xda-developers.com/forumdisplay.php?f=448
(informative thread here: http://forum.xda-developers.com/showthread.php?t=519523)
note: mkbootimg with --base support is in donut and master (or find the patch on gerrit and apply it to cupcake)
First of all, the reason you cant unyaffs anything other than system.img is because they aren't YAFFS images. boot/recovery is kernel+initrd like in any normal linux bootimage scenario (see more below).

Building a custom kernel and recovery binary
HTC hasn't yet released the changes they have made to the hero/dream/magic kernels, 32A board, so you can't just compile a kernel from the AOSP. I haven't tried it yet but this patch might work on hero too:
http://forum.xda-developers.com/showthread.php?t=548061
EDIT: HTC Sources for dream and magic at http://developer.htc.com
For building a custom recovery, it's better if you use cyanogen's recovery code, found in his git : github.com/cyanogen, because it already has menus for nandroid and other tools, but you can use the recovery code from AOSP too (cyanogen's one is a patched version with a lot more features, http://forum.xda-developers.com/showthread.php?t=523558). To make a custom recovery you need to change the recovery binary (because the press event of the hero trackball has a different keycode, 191), the kernel and the init scripts. Actually i don't remember what else I've changed to make cm's recovery working with hero (the recovery that we are actually using here), I'm at work now, but i'll check later and post more details, or you can just unpack the recovery and see the changes .
First post updated.
Nandroid only backs up the partitions in the main storage nand, but radio and spl are flashed to the radio's own nand flash. Whether it's possible to dump it or not I don't know, but honestly, I don't see why you'd want to. Radio images are available through RUU's and I don't think editing would be an easy task

Sometimes, new radio images appear on new phones. That is why I am looking on a way to extract it.
very useful thread.
Very nice tutorial, thank you!
could you please specify a bit more on how to clone from android's git and then build the mkbootimg and mkbootfs (just make, right)? I tried and I keep getting a "fatal:server dumped connection" error
Are we able to modify an official ROM (also for hero). Which shows up in RUU as INFOsignature checking... failed. Am I able to change the kernel and make it work?

What command do you use?
In fact i won't be able to explain you better than that page: http://source.android.com/download
Following that how to, you'll be able to sync an android branch You can learn more about git, branches and more here (Repo and Git resources)
The sync is long (2.9Go). Then, to build mkbootimg and mkbootfs, you should do a generic build of android going to source folder and issuing the 'make' command.
All that will be part of my upcoming "How to prepare your own kitchen and useful scripts".

Well, to grep the system from a windows RUU exe file you should launch it and then look in your user temporary folder for a rom.zip file in a {uid} subfolder. It contains the system and boot img files.
You then need to make an update.zip package from them. Have a look to someone's hero custom rom and to it's update-script to see how it is achieved. My 'How to' gives you all you need to understand update.zip packages and to extract system.img.
If you are porting a Hero rom, no need to change the kernel.

Thanks so much for this amazing information, however how do i stop getting hit with the infosignature failed error? is that the kernel or the hboot? it says 12 signature verify error.
Oh, I do have the source and I am running my own donut build on my dream with some of my spice, but the problem I was having was cloning that exact project (mkbootimg) from android.git.kernel.org using git, but when I read what you said, I remembered that when you make the build, it also compiles several tools and i overlooked checking the out folder for it, kind of dumb on my part since I had already pulled the fastboot tool from that build and added it to my own bin, i guess mkbootimg and mkbootfs should be there too, right?
i tried running androsign and got this error
Code:
[email protected]:~/android/dev/sdk/tools$ ./androsign META-INF.zip
Exception in thread "main" java.lang.NoClassDefFoundError: testsign
Failed!
[email protected]:~/android/dev/sdk/tools$
if i use a ROM of one device on an other different device, I think I must build a kernel on my own, is that correct?
but what config should I use? a config from my current running ROM? then I think I must make it suitable for new ROM, what options should I care about?
for example, if I want to run a AOSP 2.01 ROM ( system.img) on a Magic 32A device with SPL 1.76, and now I am running a SenseUI ROM which kernel is 2.6.27, I think I should build a 2.6.29 kernel from the git tree, and ensure it will work with camera/bt/wifi/trackball of my device properly first .
how can I make this step successful?
other hand, the dynamic lib files(.so) with the system.img can be incorrect. so, I may need to build them too for pairing with the kernel I built in previous step. I think applications will work properly because they only care about if the interfaces of kernel and lib is correct. for that, also there some config job (like build.prop, etc) to do, is there a list of all of these jobs? and what values can I refer to? the original ROM (Magic 32A SPL 1.76 working ROM here) ?
am I right? what should i do and what are in those steps? are there some doucments I can read from?
Thanks for the good summary. Just one question, where did testsign.jar come from? I'd like to get the source. Thanks!

If I want to customize a ROM that I have in update.zip format, do I just manually modify the contects of the update.zip and change the update-script and build.prop files or should I be doing this another way through an IDE or something?
If so, can someone please link me to where I might get some relevent info?
Thanks.
dsixda's kitchen will let you pretty much cook and modify any ROM.
I wouldn't use the root function on there, but if you look at the No Idea Blog link on the first page of that thread it tells you how to add root permissions if your ROM doesn't already have them (it's really easy).
Also, if you're on Windows and don't like the fact that you can't use the kitchen to its full potential, you can download a copy of Ubuntu Linux and VirtualBox (both free) and run Ubuntu as a virtual machine within Windows. Alternatively you can try WUBI as pointed out by kendong2 here
Using the kitchen will ensure that your customised ROM is signed - Amon RA requires signed update.zips, I think there was something called Clockwork Recovery which doesn't need the package to be signed.

Thanks, I'v already managed to add root myself a few times to various ROMs so i don't think that'll be an issue.
Does the ROM need to be re-signed on each modification? Which is why I wouldnt be able to edit it manually?
Thanks again.

yes resign after every update. just unpack, modify, repack and resign. not that complicated if you get yourself some handy scripts (write them or use dsixdas kitchen).

As far as I know yeah (unless you're using that other recovery image I mentioned). It's pretty easy with the kitchen - press 9 and it cooks the ROM. Takes about 2-3 minutes for each bake - its flashing the ROM that takes ages.
You could sign manually, I'm sure I found a tutorial on how to do that when I was modifying some apps.
It works fine on OSX too. If you read the first post, he does say some things won't work on Windows. Like I said, you could use VirtualBox or WUBU which will save you the hassle of extra hardrives, partitions, dual-booting and all that.
Q
Ok, got the kitchen open under linux now, first question is this, the ROM i'm using doesn't have a system.img, it has a folder "system" so it naturally won't let me continue in the kitchen without it, how do I solve this problem?
Thanks.
To customise an existing ROM, extracts all its contents.
In the kitchen make a folder starting with "WORKING_" the underscore can be followed by any name of your choice e.g. WORKING_ALIASNEOROM
Inside that folder paste the boot.img, system, META-INF and data (if its there) folders from the ROM you extracted.
Inside the META-INF folder delete the 3 files - just leave the com folder.
After that you should be good to go with the ROM.

Thanks a lot, really appreciate the help.
One more question, hopefully the final one, when i remove apps or add them to the relevent folder, are permissions and linking taken care of automatically where necessary?

No problem, I was in your shoes a couple of weeks ago! Yeah, you just copy the apks - worked for me so far.
Most ROMs come with a data/app folder, but incase yours doesn't just create it next to the system, boot.img etc and then in the update-script add:
Code:
delete DATA:app
copy_dir PACKAGE:data DATA:
set_perm 1000 1000 0771 DATA:app
before the format CACHE command.

Where can I find the syntax for this file? I like to understand the commands so I can use them properly, i get that set_perm is setting permissions and 0771 are the permissions being set, but what are the "1000 1000"?
Google wasn't my friend this time and I couldn't find a syntax.
Have a look in here, I've not got enough Linux experience to tell you how those permissions work. I update that file by comparing ones from other ROMs and slowly got the hang of it.
Cool

Just failed two flashes because of:
1) because i conned the kitchen into setting up the working folder (by putting a fake system.img) it didn't delete the symlinks so i had to do it manualy (after trying to flash then figuring out why it failed) and
2) it couldnt chmod "su" because it didn't exist, strange since i was working based on an existing ROM and didn't delete the "su" binary.
Question: How and where do I change the build name that shows up on the device to my own name?
EDIT: 3rd flash was successful but on boot it hangs at the HERO screen, logcat just says "waiting for device". Ideas?

That's what I don't get, the update-script isn't edited by the kitchen right? But the chmod command in the update-script was from the same ROM, so surely it's "su" binary should be in the same place the update-script looks for it, or am i missing something?

As for your adding that info from Ash to your kitch, I think it would be useful because I forgot the last line (setting permissions) and it just caused my ROM to hang on boot, reflashing now and hoping adding it was the fix. Will update this post once complete.
UPDATE: Still hangs on boot even with that line added. Where do I go from here in debugging since I can't get logcat?

If you used my instructions about the WORKING folder earlier, then you don't need to use option #1 in the kitchen to setup working folder - that's only if you're working with stock images. The result of that command is a WORKING folder - which you already have by extracting the files and making that folder manually.

You only need the permission twice if its for the recursive set, because the first is the directory and the second is it's contents.... or so I believe.
I was wondering if ther was a way to browse the img files created when you make a Nandroid backup. I sorta forgot t make a backup of swype.apk before I themed it with Metamorph. It looks nice and all but I want the OG handy in case I get tired of looking at it. Thanks guys.

Well I am desparetly trying to cook a NAND build for my HD2 but there is pretty much less info available for me [a big NOOB in cooking] to try out my luck at cooking..!!!
So I'll appreciate if someone would put some light on it..!!!

Finally the tutorial
Make your own Android Build for the HD2 by domineus I have always lived by these words- if you give a man a fish, he can eat for a day; but if you teach a man to fish you can eat for a lifetime. Android on the HD2 has always been an interesting thing for me and I know a lot of people that want to create their own builds, but have no idea how. If you ask a build creator or maybe someone in the htc-linux-chat how to get started, there may not be an answer. In fact, some of the perplexing behavior has left me puzzled in several ways - as if how to get an android build is a vaulted secret of knowledge like the holy grail. To be honest, it's not. It's a bit of hard work, a few nods in the right direction, and ultimately it's a community involved project. Just like miui development is a community project spanning actual continents to get this thing on our device every single week! It has led to a lot of questions, in my inbox, of how to begin. For a long time, the answer to the question was not answered until Cass helped me out. I want to do the same and contribute how to get a build of miui (or any android build) to the HTC HD2.
Things you will need
In order to properly start android development, it would be a good idea to make sure you have the following (a lot of it is no duh when you think about it)
A computer running linux
I can't stress that enough. While there is a lot of things you can do in windows, you will need some sort of linux distro in order to get android properly running on your HD2. There are a lot of linux distros you can use; with many using ubuntu as it is the most user friendly. I use Fedora and I am quite happy with the results. It's simple and effective. It gets the job done. Get a distro that you feel can get the job done.
Android SDK - either windows or linux
Android SDK is something that can be freely accessed and downloaded from the following location:
http://developer.android.com/sdk/index.html
It is a developer environment, but probably the most important thing you can use here (for the time being) is logcat. Logcat provides you to visually see the libraries and files working together to get android to work as well as if you run into an issue, it is the first thing you should resort to. For instance, boot reloop? Take a look at your logcat and try again.
A kernel
There are quite a few kernels available for android previously and they are divided into evo kernel or nexus one kernel. Many builders have transitioned to an evo kernel for PPP and a few other nice details but it is totally up to you. I highly recommend hastarin's kernel. For most of the time, it works well. But as you have noted, on MIUI, it hasn't been working as fantastic on other builds.
Donor Files
This is a bit difficult to find because it appears that the files that work best are nexus one builds without CM6.1 modification. So far, only one chef has that and it is tytung's nexus one build. Regardless of whose files you're using (e.g. tytung or darkstone's system which is the preferred choice) you will need a well working android build. You will be pulling several files in order to port.
MIUI itself (well any build honestly just miui is a good example)
This is a given. However, if you download from miui.com you will probably have an untranslated rom with odex files. That's bad. And in Chinese! It would be a good idea to browse the English forum for a deodexed rom with appropriate english translation (apps and frameworks)
-If pulling files from windows, you will need this
system extractor
http://uranus.chrysocome.net/linux/explore2fs-old.htm
I use that if I download in windows. It's relatively straight forward and it allows you to pull the files you need from the system.ext2 you're using and copying them to folders necessary.
build.prop
This you will need. You can find one here:
http://www.multiupload.com/B59IU3S6XY
Patience
Probably the most important thing. One thing I have noticed is you need patience to make it through. Sometimes, your build works, sometimes it doesn't. And it is difficult to still keep going. But gotta pull it all in and keep trying...it does pay off.
Okay so you have your files, a nice linux distribution, your build you want to port (MIUI preferrably) and you're ready to go. Now it's time to begin the process!
Step One - The Setup
I usually grab my files in windows before transitioning to my linux distro to finish the process. If you using windows 7 and you are using explore2fs, you will definitely have to right click on the exe and make it compatible by selecting compatible with windows vista. The file should also need to be run by administrator. If you don't know how to do that you can google compatibility in windows 7.
First thing is first. Create a new folder, you can call it donor_files if you want because name is arbitrary. The most important thing is to just name it. Within that folder, create a new folder called system. Enter the system directory and create a new folder called etc. Within etc, select Once that is done, create a new folder within etc called firmware. Once completed, return back to the system folder, create the folder called lib. In the lib folder, create a new folder called hw. So your folder should look like this:
Folder Name
-system
--etc
---firmware
--lib
---hw
So far so good? Excellent. Now, if you're in windows you will need to do a few things. Extract the system.ext2 of your donor build and place it somewhere you will remember (like your desktop). Now open up explore2fs, select file, and open image file. Under files of type (drop down), select all files and navigate to your system.ext2 file. You should now see the ext loaded on the left side of the program's workspace. Located is a very small + that allows you to view all directories in your ext2 file. Click that.
You will see several system folders on the left and files on the root. Since you haven't selected a specific folder, in the right hand view, you should see the file build.prop. If you did select a folder (like app) you will see some files. And that's okay too. Get a feel of the program.
Now you will do a test file pull. On the left hand side, select the folder etc. On the right window, you will see several files. We want AudioBTID.csv. Once you see the file, right click on AudioBTID.csv and select export file. Navigate to the donor file folder (or whatever you named it) and place the file in system/etc of that folder. Congratulations you just pulled your first file! But you will need a lot more files. Within the same directory, pull gps.conf, hosts, media_profiles.xml and the ppp folder. Now, navigate to firmware and pull the following files:
BCM4329B1_002.002.023.0360.0362.hcd default_france.acdb htcleo.acdb
BCM4329B1_002.002.023.0436.0439.hcd default_nel.acdb yamato_pfp.fw
bcm4329.hcd fw_bcm4329_apsta.bin yamato_pm4.fw
default.acdb fw_bcm4329.bin
Ideally you should not be able to find htcleo.acdb. You can find it here
http://gitorious.org/xdandroid_leo/q...eo/htcleo.acdb
Now in explore2fs, go to the lib directory and pull these files and place them in your lib directory:
libcamera.so
libcamera_client.so
libcameraservice.so
libhtc_ril_wrapper.so
libmm-omxcore.so
liboemcamera.so
libomx_aacdec_sharedlibrary.so
libomx_amrdec_sharedlibrary.so
libomx_amrenc_sharedlibrary.so
libomx_avcdec_sharedlibrary.so
libomx_m4vdec_sharedlibrary.so
libomx_mp3dec_sharedlibrary.so
libomx_sharedlibrary.so
libomx_wmadec_sharedlibrary.so
libomx_wmvdec_sharedlibrary.so
libOmxCore.so
libOmxVdec.so
libOmxVidEnc.so
libqcomm_omx.so
libstagefright_omx.so
Once those files are pulled, navigate to the hw folder of the system and pull the following files:
sensors.htcleo.so
lights.htcleo.so
Once those files are pulled, you can save your donor files to a flash drive and then boot into your linux distro. Login to superuser in terminal. For fedora, the proper method involves typing in su --login and entering your password you set up. Minimize your terminal window.
Extract the miui (or any other build) to your desktop (the focus is the system folder). Ensure the rom is deodexed and in your own language (if its miui, you will have to apply the proper language translations). Now copy the files you pulled from your donor build and apply it to the appropriate folders (usually a copy and a paste-literally). In this instance there will be duplicate files, overwrite them. That's the point! Do not forget the build.prop file I linked to earlier. You should add that to system folder.
So the files are copied, the next step is to restore the minimized terminal window (the one that is logged in as root). cd to where your system is located (not to the system folder itself). Now you will have to enter the following commands in terminal
chmod -R 777 system/etc
chmod 755 system/bin/*
chmod 755 system/xbin/*
rm system/etc/firmware/default*acdb (if you have sound in call issues)
touch system/etc/ppp/active (If you have latest wrapper and need ppp)
chown root:2000 system/bin/pppd
chmod 4755 system/bin/pppd
chown root:root system/xbin/su
chmod 4755 system/xbin/su
chown root:root system/xbin/hci*
chmod 4755 system/xbin/hci*
dd if=/dev/zero of=system.ext2 bs=1048576 count=256
mke2fs -F system.ext2
sudo mount -o loop system.ext2 /mnt2
cp -rp system/* /mnt2
sudo umount /mnt2
A few words on this that I must bold. the /mnt2 directory may not exist. If not, try mnt, that usually works
Once this is done, you will have a nice system.ext2. The only thing you'd need now is a rootfs, a kernel, clrcad.exe and a startup.txt file. Once that is done, you can test your build out.
Any questions
Special thanks to Cass and the htc-linux-chat for the few pointers they gave me.
The guide is by "domineus - http://www.miui-dev.com/" & I take no credit what so ever
Thanks to "white-energy" for giving us the link..!!!
Hope to have many more Chief's for our HD2, so that we [especially me] can satisfy our hunger to try different builds/ROM's..!!!
Happy Cooking..!!!
PLEASE PRESS THANKS IF YOU FOUND THIS THREAD USEFUL..!!!
+ 1... nobody wants to share information?
I don't know if this help but you can try
http://forum.xda-developers.com/showthread.php?t=897940
These kind of thread pop up once in awhile, but it's going no where, I've never seen well known chef show up in this kind of thread.
knowledge is power, maybe they dont want to share the power
Can anybody out there give us a step by step guide for cooking a NAND ROM for HD2..???

I've been looking for something like this. I want to create my own build for the recovery flasher. I guess the only thing needed would be how to convert from regular nand to recovery.
Thanks bro.

Are you sure its the only difference? Are the nand drivers stored only in the bootimg/initrd and not somewhere in the system.img?
yes or no will do for me thx
Is there a way to edit system.bin files, that comes with the NAND builds. I suppose that is where the ROM is. I want to unpack, edit the included apps and repack. How it is done? How the bin file is done. Google does not give any satisfiable links, did a quick search, though...
i am confused
Which explore 2fs do I download? There are 3 different ones one for binary one for code and optional update source code. I am a noob and tired of not having roms I am happy with. I have windows 7 and xp. I realize this will take time and I am good with it everything thats worth anything takes time.

I think you mean system.img not system.bin
You can extract them with the unyaffs.exe or with the unyaffs command under linux. I have written a guide with attatched utilities here
Additionally birksoffsjunk (seasoned WM guru & chef of ChuckyDroid, ChuckyROM, & Dexter) has made a batch program to make this process easier. It's a work in progress & somethings are still buggy so follow the thread
Between the utility birkoffsjunk made & the tutorial I wrote you should be able to successfully edit & run your own build. Hope this helps.

It's an archive that can be decompressed and edited thru linux.
White-Energy use system.bin in his rom
Regarding initr and zimage, there is a guide that you can point me on ?
Thank you

I have only green HTC
Hello
I would like to use Android on my HD2. I was searching and testing many ROMS but I didn´t find any rom which is usable for me. I would like to have a ROM that is without Sense, has Multilanguage support and is on Android 2.2 version.
So I decided that I would make my own.
0) I was reading
HTML:
http://forum.xda-developers.com/showpost.php?p=10291851&postcount=1
and made this procedure.
1)downloaded some ROM from here
2)unpacked this rom in linux with :
Code:
unyaffs system.img
then I got this directories:
Code:
app bin build.prop etc fonts framework lib media usr xbin
3)I downloaded update-cm-6.1.1-N1-signed.zip from CyanogenMod Forum > Downloads > Stable Mod > Nexus One and unpacked. I got : META-INF system boot.img.
4)I copied everything what was described step 0 from directories from step 2 to directory system from step 3
5)I downloaded and copied build.prop from step 0 to system
6) I updated permition like it is described in step 0
7) I created system.img with command : mkyaffs2image . ../system.img
Then I copied this system.img from linux to my windows and put this file in directory in which was different NAND rom. (replaced system.img). After that I flashed my phone and it did not work. Screen was frozen after booting and only green HTC was on display.
Can somebody please help me and give me some advice or some small howto. Does anybody know what can be wrong?
Thank you
Michal Fichtner
I appreciate the guide but damn that is hard to read. It really needs some sort of structure to it, titling proper paragraphs etc.

Hello y'all,
I am trying to write a command-line (in the locale execute plug-in) that will copy a file "/mnt/sdcard/GpsConf/gps.conf" to "/system/etc/gps.conf"
(so that i don't have to "set" the content off that file everytime i flash my SGS with a new custom ROM. It will become a "task" in tasker.)
Who can help??
already tried this:
! cat /mnt/sdcard/GpsConf/gps.conf > /system/etc/gps.conf
The problem (as far as i get it) is that /system/etc is read-only......
?? help ??

You need to mount your /system partition in RW (Read/Write) mode, then remount it in RO (Read Only). I'm not sure what the path's are for the Galaxy S though. It's different than the Motorola Droid X2 (which I am running).
