This a simple and quick guide for everyone who wana make or just modify their own HTC DESIRE ROM's.(Rooted ones)
For example you downloaded a nice ROM from one of devs here, but they removed some application that you cant live without. Now you dont need to beg them to add those files back, simple add them your self and flash your rom.Missing APK's you can get simple by downloading any stock rom, than extract them and put them in your new ROM.
After you extracted files provided (c root recomended), you will see 2 maps
"Sign ROM" and "tools"
Signing ROM's:
After you modifed your ROM zip file, simple put it in "Sign ROM" map, and rename it to update.zip.Than run "Sign.bat" After the process is done you will get another zip called "update_signed.zip" which you can now put to your SD card and your ready for flashing. Note:JAVA SDK files are included, you only need to have normal java installed.

Pushing recovery files from windows:
Now to flash your ROM you dont need linux anymore, simple enter recovery (Power button+back, than select recovery...), and than in the map "tools" run recovery-windows.bat. Than you will get standard screen where you can flash your roms, partition SD, clear data and so on..
NOTE: You need to have HTC Sync driver installed or your phone wont be detected (you can get them from HTC)

(Thanks GeoTrail for link)
would this tool work for the HTC Legend aswell?
For signing roms yes, for pushing files not sure if Desire and legend use same files..
Ok this one is simple, but this is only how to add/delete several apps.
How about going little bit more deeper?
Well if you wana go deeper, you can download costom kernels with overclocks or low volatege and replace the ones in rom, or those circle battery mods or costom boot sounds and so on...Basicly your replacing/modifying original files. But this is just quick basic guide for basic stuff, let real ROM developing and costomizing to the developers who are good at it.
As far as hardware support goes is it the kernel that provides everything? Basically if I take an N1 rom (like cyanogen 5.0.6) and change to a desire kernel, is it likely to just work perfectly or are there other bits in the ROM that are likely to need changing?
Of course you can just use dsixda's Kitchen which is cross-platform and quite straightforward to use.
You just add the update.zip file you want to change, remove/add any apps you want and make any advanced changes you want too.
Select Build ROM and it'll create the new update.zip that you can flash to phone.
I've used it on my Desire without problem for adding/removing apps.
Well that kitchen is nice, but still..you need to downlaod virutal machine to make it run under windows or Cygwin tool than download JAVA SDK..setup lots of things.
My point of this thread was just vey basic and simple way to quickly add/remove/costomize files from ROM, without installling and downloading lots of tools, and quickly install it on Phone and test.
Sorry, I wasn't meaning to undermine your work. No doubt you've spent a lot of time creating this and trying to contribute to the community. It's far more than I can say for myself.
I was just pointing out there's something already out there, and more capable than this.
It's definitely good to see people helping out the members and this is definitely something useful
Everything is cool TheAshMan, and thanks for you link, im sure some enthusiastic people will try some advance things like that. But even my self im not big expert about Linux and phones, i do have great knowledge about windows and computers, but dont have much time for this area.
Screen shots on how to use this would help, I've come from cooking my own WinMo ROMs and wuld like to give this a try if possible
Also, as I use W7 x64 is it best to run the .bat files as an admin? Had issues using Windows methods in the past so have been using Linux to get rooted
I'm also using Windows 7 x64.
About running bat's as admin its not necessary unless you have some kind of UAC high settings, or running on some kind of limited user account. I never run this bats as admin and they work fine.
Basicly download some stock rom, or someones rom. And simple add or remove files inside rom.zip/system/app/
If you dont like facebook for example, just remove Facebook.apk and facebook.odex(if its present).
After your done with that, rename ROM to update.zip and put it in the folder
C:\Desire Tools\Sign ROM\ and excecute "Sign.bat" , and it will create signed rom with name update_signed.zip.
http://img99.imageshack.us/img99/2921/signedrom.jpg
This is just some base, im not gona explain you about ROM deodexing, framework, boot images kernels and stuff, because im not expert at this.
Now you can put that file to root of your SD card.
Now you can test it on your phone.
Shut down your phone. Turn it ON while holding back button.You will see Bootloader selected, press power button again. Than Recovery will appear, you can navigate down with volumen UP AND DOWN and select Recovery and press POWER button again to select it.Phone with Red triangle will appear on your phone. Now go in map C:\Desire Tools\tools and excecute "recovery-windows.bat"
http://img213.imageshack.us/img213/1894/pushfiles.jpg
And on your phone you will get that screen with green letters where you can select to 'Flash zip from sdcard' ,where your signed rom will appear.(You need to wipe data before from the same menu)
I hope i made some thing clearer im writing this from work so dont have much time
Right, got a ROM and added 2 .apk files to the /system/app folder and now got a signed_update.zip...is that it? They'll be on the device from the start?
Seems to simple to me!!
How can you add a new radio? Or change the version number in About phone>Software?
Yea thats it. About those other things..Google is your friend...
edit mate
when i flash it says:
E: Can't find update script
rom.zip/META-INF/COM/google/android/update-script
Did you touch that in ROM? If you didint, than you removed something that you shouldnt.
Can u also remove apps from rom that you don't like by this method.
-------------------------------------
Sent via the XDA Tapatalk App
Yea, thats the all point of everything i wrote here. Very simple way of very quickly removing apps that you dont want from the rom before flashing it.
Also, you need to watch out, and to a bit experementing. Because sometimes if you remove some crucial app, you will start getting random crashes of applications or random bugs. Allways make a copy of original rom.
For example if you remove HTC-IME.apk, you wont have any kind of keyboard in the rom. Making it un-usable
Somebody already asked how to add radio update, is it maybe included in Modaco r3 rom(the one without apps2sd and modaco additional stuff)?
Tnx for help
I'm sorry if this has been asked before, I've done a search and can't find anything.
I know there's a few dumps of WP7 roms on the forum. But my understanding is that these have been from the rom files rather than from a phone. My question is is there a way to get a copy of EVERYTHING in the rom/nand from a working WP7 phone onto a computer/drive? I know there's tools on this forum for editing WP7 roms, but again, my understanding is that those roms weren't ripped from a working phone, rather from the rom file.
I know someone has used a HTC TyTn and has terminaled into the bootloader to send commands to dump the rom. Is this possible with a WP7 deivce? Say the HD7?
Any advice would be appreciated.
Thanks
yes i believe ppl flash new roms to unbrand their devices, you should check the devices forum, bet ull find roms there..

the rom's here on the forum(except the one's for the hd2) are original stock rom's for wp7 phones that can be flashed on real wp7 phones (with the same vendor ID)
you can't dump the actual rom from your phone right now (maybe later,but it will def take some time)

What phone(s) can you actually do a dump of the actual rom from the phone right now?
I understand some phones have things like clockwork recovery or magldr installed and use that to write new roms to the phone. Can the same programs not read (or backup) the current rom?

I can only talk for wm/wp and only from wm (6.*) you can dump the rom using a tool that is installed on the phone .
if you had a jtag or something like that you could dump (read the ROM/NAND and copy it) almost any phone.
but a jtag is hardware and it cost money (lots of it) and you need to know exactly how to work with it and you would need to open your phone (till the last screw)
I don't know clockwork .
magldr is something like a second bios (not right , but for you to understand) that help to start the os (normally the spl/hspl will do that )
magldr is used only for playing tetris and to load android/wp7 to a phone that isn't build to run that kind of os
it can only load something , it can't dump a rom.

What tools can you use in WM6.* to dump the rom? I've read an article where someone used terminal commands and did a dump through the bootloader. Is there another way to do it?
I know about JTags, and am not touching them!
My point with clockwork and magldr is that if you can write (load) android/wp7 to the rom/nand, surely you should be able to get it to read from it?
It seems like either there's no way to do it with wp7 yet, or at least I've not found a way. But I was thinking if you can't do it with a real wp7 device since there's no clockwork/magldr, then can you take a dump of an HD2 with wp7 loaded into the rom/nand?
I have searched for a samsung focus stock rom in the past but I couldn't find it anywhere? have you seen any one?

Excuse me newbieness but if I'm getting you correctly, you're saying that it is possible for my to extract the ROM from a working Samsung Focus and then write it to my bricked Samsung Focus using a JTag?
Totally possible, theoretically.
The WM/WP OS image is only a piece of data saved in a flash partition, bootloader can read the content from the flash partition out and transfer bytes to PC (no need to care about the file system, just perform flash chip level read), but the question is you must know how to communicate with the bootloader and send proper command to it. And as I know in the shipped device, the ability usually will be removed from bootloader for security reasons (e.g. eboot is useful in development phase, but it must be removed from shipped device).
Yes, you also could use JTAG to read content out but due to the same reason, the debug port on the SoC usually also be disabled in shipped device (like Tegra, it has internal fuses to enable/permanently disable the JTAG).

I think reading the OS partition when OS is running is impossible (frankly, I never verified it). Two reasons, first the OS partition should be locked by last phase bootloader or some early bootup codes in OS (just set the NAND controller in SOC), and since OS is running, many system files are in memory so the corresponding files should also be locked by OS.
It is safe to dump whole OS image in bootloader, or so-called recovery mode.
So someone basically has to install a custom bootloader on the device. Then again, if the NAND is locked, that wont be possible.
QPST and Memory Debug allow to download raw NAND and radio copy. i've succesfully one it (even found private info like passwords and contacts), but i don't know how to split it into partitions. Mb anyone will help?
Maybe starting a new topic about it here would help. Might attract the attention of some other devs.

Could you describe how you do that?!
How to do this?..
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://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).

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.

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
//My Bravo doesn't have a Q&A page either -- it needs one that's not my PM box...Don't PM me on how to root your phone and flash CM7 -- read one of the 5 guides on the first page of both General & Dev...:silly:

Hi folk.
I wanted to know a few thing.
As many ppl I have buy a cheap phone ( SC6820 based ), it is already rooted and everything work nice atm.
But since I was dev ( I have made 3 years study in IT university, then I become nertwork manager / architect) I rly want something but something that can be impossible ( I have poor knowledgement in android )
http://forum.xda-developers.com/showthread.php?t=2121128
Explain how to port android 4.X on other device, bit since there has been only few changes since android 2.X
I wanted to know if I can make the same to use a CM7 with my andro device ?
I already know few things :
Partition are not the same than standard android, so I will have to change them ( I will have to change fstab files but IDK what exactly )
They also use non standard frame buffer so I will have to load the correct driver ( /system/lib/modules -- /system/lib/hw I guess )
but I have already see that boot loader can be a serious problem I know what it is in computer but in phone ? use the standard kernel of the device will be enought ?
This is my main project.
but since CM9/10 can be run with 2.6XX kernel why not try that ?
can it be apply with this rom ?

I think yes but since I don't have source of my kernel i don't rly know if it is rly doable.
Galaxy 3 is less powerfull than my device so if it run nice on galaxy 3 no reason it doesn't run on my phone.
This are only trick but since I have my dev environment already build, I can make effort, compiling, modding etc etc
the phone :

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
sry for bad english
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.
