[Q] How to port/cook an Android ROM for HD2 (chefs please help)

Hello
I'm looking for some hints about the subject: how anyone can take a shipped, let me say, HTC Desire rom and let it work on HD2.
I'm not talking about doing heavy tweaks, modifications and so on... just to take a stock Android ROM and have it working on HD2.
I asked to some chefs and received some hints but It's not enough.
I don't want to think that this is a "secret" and I think would be great if some chef would share his experience/step-by-step instruction on how to do this.
As I said before, I think we could start just with simple porting of a stock htc desire ROM, just to understand all the steps. I think that further steps on how to customize and tweaks will be explored later and anyone could experiment itself.. but we need a basic starting point.
Some step by step instruction will be great like:
1) Download shipped rom from here .........
2) unrar it in linux folder
3) copy this folder, rename the other one, dowload this file, copy this...
4) execute shell command XXXXX
5) copy on your sd card
6) boot...
of course I know it's not so easy, but is just an exaple on what I ask here. I think there are a lot of other perople looking for this.
Thanks to any chef/dev that would to explain to our noobs how to get the "magic"
p.s.
I ask the moderators to keep, if possible, this thread in the Dev forum... this because we need help from devs here and in the Q&A forum it will be never noticed.

I came across this the other day that maybe of use:

Yes, I was pointed to that thread too. If you look at the end there are some questions I did. The problem is that is based on MIUI... That is already a custom ROM.
I think the better way to understand the process (not just do it) is to have hints on how to port a standard/stock HTC DESIRE rom.

Ideally the same way. In theory it should work...I never tried because sense builds (especially hd ones) are very laggy

Hello, I was just replying on the other thread to thanks you for the answers
I will try to follow your guide to port a stock desire rom (strange that are laggy for you... for me they fly...)
Anyway it's still something not clear about the donor files... If it's ok to take them from an already HD2 working rom or not.. but I will ask on your thread, avoid to make confusion

no one tip from the devs?
I'm start thinking that instructions on rom cooking for hd2 is like a secret

I've asked this many times, but as you said, no one seems to want to share this "secret"...

literally it can't get that much easier...

I think you are the only one that shared your findings.. Hope others will do.
Anyway I'm trying just know your guide.. I'll let you know.

good thread and wish everyone to share your cooking knowledge here.
its good for the XDA community.
i am a newbie to android system and trying to cook my own rom too.
pls ask/share your question here, lets make it easier to cook/modify android for everyone.
of course this cannot success without chefs support.

you can start with one of the hunderd rom that chefs already cooked. This thread is just to ask help with cooking a rom, you have not to wait.. you already can use android daily on your phone.

I have had success building with this guide but cannot get it to work with cedesmith's new initrd.gz. Does anyone have done tips on how to build with the new initrd.gz?

Did you cook a MIUI rom or a Sense rom or a stock android rom?
For the cedesmith's initrd.gz I was thinking the same thing.. maybe we have to ask directly to him.

wow, both tyween, and rafpigna, started from this, to now:
Rafroid
Typhoon
best roms on xda. Really nice work guys!
But still, no one shares the "secret" I have tried several things myself, but it didnt work. Would really appreciate if someone could share how to port a rom to the hd2.

Yeah would be great if tyween and rafpigna let us know how they managed it, what guides/reference they started of on or if they have any tips for us etc

I totally agree, I would definitly cook my own rom if I knew how to...

I've been following that thread and was inspired to install ubuntu so I could join in the fun. This in turn lead me to updating my BIOS, & modifying my power supply to allow a second hdd. Now, I'm stuck at properly installing GNU make haha.
Thanks for the contribution Lithid. One request unrelated to CMC, could you post the tools necessary in ubuntu to compile an HTC kernel? EVO's got an OTA update to 4.67.651 Android 2.3.5 this included a new kernel and I'd like to play with modding it. I am aware this is above my pay grade so to speak, but enjoy the challenge of learning something new.
Once again thanks Lithid.

Ummm read the guide in the link lithid posted
We are legion, for we are many.

Yeah I did dumbass but I know nothing of the programs needed nor do I have a computer to even run them on. So ill ask again. Has anyone been able to compile CM7?

Well dumbass then you can't compile the nightlies you need a computer to do it ffs if you don't know how to do something learn if you don't have the tools then you can't learn this thread was for people to compile the nightlies for themselves alot of ppl have gotten it to work if you read the thread you'd know that, your question really makes no sense since you don't have the tools to compile are you asking someone to do it for you, being vague in your question then calling ppl dumbass and having a smartass response isn't going to get you a handout. I can compile from source, but with your response I'd tell u to shove it before I compiled anything for you

[MINI GUIDE] Phone Vocabulary - x8 Specific

This thread is being created to explain, in short, a few common phone 'terms.' Now although there are many threads explaining the same thing they are 'thicker' and written differently. A different guide will help a different person. I think it is valid that there is more than one explanation of the same thing. If you have ANY suggestions, please leave them in post form below. I have explained this relative to the Xperia x8 and this is why it is in our territory.
Remember that this is a MINI guide. So not every term in the android language will be explained. For a more complicated guide see HERE or on the everything x8 w8 thread here. Both guides are different.
Anyway Here is a mini guide about phone terms:
A ROM stands for Read Only Memory, ususally on this site referring to the phone's internal memory where your apps are stored. It's like an operating system. (OS) When people say they're flashing a new ROM, it usually means they are installing a new 'operating system'. A custom rom may have new features different to the STOCK rom.
The term Stock usually means the version of something installed by the manufacturer. Or in other words, the stuff already on that thing.
An .APK is a Package on Android. Usually you will meet these when installing apps on your phone. This is, simply put, just a file extension, like .exe on windows.
Rooting is simply giving your phone administrators rights. No roms or anything. Once rooted you could install clockworkmod which would allow you to install a rom that would work on you STOCK kernel (the one that comes with xperia).
A kernel is a set of instructions to a phone. different kernels or custom kernels (not stock) enable you to flash some more advanced roms as not all roms will work on STOCK kernel.
Also, in most cases, different kernels allow overclock and undervolt. These things allow you to make your device run faster.
Unlocking your BootLoader is required to install a custom kernel. Unlocking a bootloader can be difficult and if done wrong, can brick your device completely.(make it useless like a brick) This is why I did not do it until a few weeks ago - because I was scared. If you do however find yourself bricked, look to my guide no further than HERE.
You flash kernels with Flashtool. But you MUST have an unlocked BootLoader to do this.
If I was to recommend a rom, I would say MiniCyanogenmod (CM for short). The developer, nAa, focuses on getting the galaxy nexus android - pure version. Check out my review on the stable ever wonderful MiniCM9 HERE.
Links to Flashtool, ROMS and other things mentioned will be in my other guides hyperlinked in the article.
Please be generous with the 'Thanks' if you appreciate my effort.
Special Thanks to I Am Nice for his consistent helpful feedback

You should better explain what kernel is. Like conection between hardware and ROM

Pls don't disrespect chris. I can tell you he knows what he's saying (he didn't get to become RT for nothing).
I admire your efforts, but please add more definitions. For example: you didn't really explain what "bootloader" means. And like chris has said, it's already explained (in morr detail) in another thread. Hopefully you'll add more jargons in the near future. Good job though. :beer:
Edit: you may want to report those users thay are stalking you.

Thankyou. After reading this again. I see that I have crossed the line on that one. Apologies to Chris and thanks to you. :fingers-crossed: I was quite tired and wasn't really paying attention. But I have typed that same line so many times that those keys on my 'board are worn out. Just a bit angry. But sorry again. No disrespect was intended.

The best Linux tool I've used is by Tommytomatoe called android-utility and I'm almost sure there is a mac version.
Has adb functions to push and pull,a logcat function uhm will do apks and jar files.
Another Linux tool I've tried was something along the lines of studio android and the last I checked that tool would set ones Linux box up to compile from source in a gui I'm guessing something like lithids.
Maybe a Windows tool to have would be win merge if it let's you compare text files and directory's to see what's different

Chk Ur framework or kernel most times problem in framewrk ...some time kernel not supported some init.d like hell lock kernet not booted if 99complete tweak present in init.d folder .. so i thnk problem in these two...!!
Sent from my GT-S5360 using xda app-developers app

this question is asking the same logic as "why is my computer slow?"
there are 78,644,223,887 available reasons why,
i'd suggest broadening your "team's" knowledge of the principles and basics of the software industry,

Did you cook your rom with kitchen...If yes then youm must sign your rom and all apps inside it.To My thoughts the rom does'nt even start this is the most common case.Check whether your rom contains boot.img and build.prop as if Kitchen din't report any error.If you modified framework please sign it with Jarsigner and other modified apps also.Now sign your rom with kitchen and then flash it.....
Gud luck,
Im awaiting your rom..
optimusinc

Best I can say is try installing the modded apps one by one..c if they work..then test ur tweaks to b if they work..n finally make the zip file correctly by comparing to other zips..mostly probably u messed up ur updater script..

i understand that you are a budding developer,
however i've seen you making threads recently on issues that could be solved be either doing research and proper utilization of the search function,
if you really want to learn i'd suggest learning it the proper way by researching the basics and understanding how the android system works, making question threads won't help you at all and it never did for everyone else,
as you can see you need to look for the answers on your own,
considering google and xda has both a search engine,
please care to look into those matters which confuses you,
try first building your own updater-script and making a flashable zip file,
proper ROM building is not easy so i'd suggest keep your heads up and learn it the right way,
also,
people will just probably troll and ridicule you with threads like this
