hey guys, just wondering how difficult it would be to do this and keep the finger print scanner. i (with no android developing experience) tried following a few tuts to try and port a 4.3 rom with little success, i managed to get it to start installing in cwm then to give a permission failure or something similar so yeah just a quick question

Permission failure? Noob here too
I am guessing the ROM you tried to port checks for the Model number of the phone before flashing. What ROM did you try to port to and if you could post the instructions here we will make this the porting thread
Given that HTC One has all the custom ROM's and kernels we need devs or someone like us who can follow instructions to start doing it. I am sure we will get help from one another and end up with custom ROM's for the MAX.
I was also thinking of doing this but just to start with i don't want to look at the fingerprint scanner and may be later we could get it working.
I am certain most people would be willing to not have a working fingerprint scanner, as a trade off for a few custom roms/kernels...
Well to start you need to make sure your Meta-Inf directory is one from the Max, you should be porting from something with the same board as well which would give you less headaches in the long run. The One would be a good starting port since they use the same boards (msm8960 Snapdragon 600) The updater script in Meta-Inf needs to be pointing to the correct device. For example and this is just an example in the beginning of the updater script which is really the instructions for flashing the rom in recovery shouldn't say something like "get prop blah blah m7vzw" the m7 being the model # should be t6vzw if you were using a Verizon device etc etc.. All mount points need to be exactly what the Max's mount points are otherwise it will never flash.. The original One mount points aren't the same as the One Max. Also the kernel from the Max is a must, plus in system/lib you need the modules as well as hardware. In system/bin you need vold, vold is device specific. In system/etc you need vold.fstab again device specific stuff. The you need the hardware directory, which is touch capacitive buttons and LED's and what not. Those may be the same as the One since they are laid out the same.. The audio should most likely be the same but you would need to remove all the Beats Audio crap from system/etc since the One Max isn't a beats device.. GSM to GSM may be an easy port, CDMA to CDMA may be a little more difficult. Although they use libril-qc-qmi-1.so I think it is, that may be a typo but that's something like what the lib path will point to, the code may be slightly different in telephony for CDMA LTE devices. That would be found in framework.jar if applicable framework2.jar..
I could most likely easily get a port done, I'm just very limited to time.. Some of the tutorials out there are very generic and would kind of work well if you have 2 very identical devices with minor changes and manufactured around the same time small example would be like the HTC Desire and the HTC Thunderbolt.. That's a pretty straight forward port with some minor audio tweaks since sound image in system/etc is different and that as well are devices that would require a RIL hack as stated above with framework.jar... That right there would be strictly smali/baksmali hacking which I have some knowledge with but by no means a master of it lol... That is unless we had source for certain things but that isn't likely by no means... If anyone is interested in getting to work I'm more then willing I just sometimes have a hectic schedule... There is more to porting then just a few quick changes if you want a clean solid daily driver port... I started to port MIUI V5 just haven't really had much of a chance to test it. I have 3 MIUI ports built all slightly altered to eventually test different hacks..
The reason I chose MIUI V5 to port is because a good deal of HTC MIUI ROMs are based heavily on Sense.. Not many of them are AOSP based anymore which to me is kind of a shame.... The Chinese must have gotten tired of so many ports popping up with a lot of broken stuff because they all use to be AOSP based and to get them ported required a ton smali hacks and now when you decompile an actual source built official chinese MIUI rom and you diff out lets say services.jar from CM and services.jar from MIUI for every line of code like cdmareceiver.smali in CM in MIUI it's i.smali then cdmareceiver$1.smali in CM in MIUI it's 23.smali.... Those aren't actual lines those are just examples but they made it damn near impossible to properly diff stuff out.. You'd literally have to go through thousands and thousands upon thousands of lines to figure out which matches what and then make the changes you feel like need to be made and then hope you didn't break something in the process.... It sucks lol...
So yeah most of the HTC devices are now MIUI converted Sense based builds and I'm hoping are a little easier to port with less changes!! But I guess we'll see?!?!
Like I said, anyone wanting to work with me I will be more then glad to lend my knowledge of Android! I need someone to get me motivated again. I really miss working on Android and building stuff porting stuff whatever.. It's just fun! Plus we desperately need some form of a custom Android really really bad.... All of us do... I mean I'm Verizon, but Sprint, the International crew, all of us....
Lets pool all of our knowledge together and do some work!!! To all reading this if you are down contact me in this thread or PM me and lets get busy!

Thanks, i just installed it via virtual box without disturbing my system.
Just got android kitchen up and running, on prting sides of things got further this time, into aroma installes but error 7 which suggested earlyer is to do with mount points, if anyone could happen to help with theese it would be fab ))
Ok this is good start, i am proud of us here
I have got Android Kitchen running on my Ubuntu via virtual box.
I tried to set my working folder and tried tried to import my TWRP stock ROM backup. It seems like Android kitchen will require a CWM backup and TWRP does not seems to work.
With the TWRP backup i got this error

So i have just restored stock ROM on my phone, flashed CWM and now backing up my Stock ROM to COOK ANDROID
@[email protected] did you miss this thread just kidding, I know you have got a hectic schedule.
Again i am extremely happy to see ppl starting to develop ROM's!
Thanks for your encouragement @Murrda
No problem.. I'm home from work already and I'm off for the next 3 days so I'm actually going to get back to working on some ports. Anyone need a hand with anything as far as questions or setting up Linux or a dev environment please feel free to hit me up!

heyy i could use some help doing this part in android kitchen. straight from android kitchens page but i can't seem to get the recovery.fstab out anyway! im on t6ul verson of the max by the way thanks
/HIDE (sorry dont know how to get this to work (forum noob here too)
Create a file under the kitchen's /tools/edify_defs folder, with the name being the same as the value of ro.product.device (found in your device's /system/build.prop file).
If the stock ROM images for your device contain the recovery.img file, extract its files from the kitchen menu: Advanced --> Tools for boot image --> Extract from boot.img/recovery.img in any folder. Then, open up its ramdisk folder, and look for /system/etc/recovery.fstab or /etc/recovery.fstab or similar FSTAB file location. Open this file to find the mount points.
See the template file in the edify_defs folder to see how to set the mount points inside the file you created. Look at the other files in that folder for examples on how to do it.
managed to flash something and get mounting things sorted ))), getting an interesting navy green screen when booting now, will let you know on further developments. its a vanilla android rom i tried insertcoin-m7-google-edition_5.0-1 to be exact

Yeah I've been trying to port gpe over to the max but I think I need the gpe kernel ported too.. I used the Max Sense kernel for it and I get a bootloop or frozen boot logo after install with no hope of getting a logcat. I didn't move the Max sense update-binary but don't think that would be an issue, both since Its gpe and I'm using aroma..

Got to exactly the same point as you, reading several tutorials online i came across this interesting line "To port Sense you have to unpack the boot.img of your base rom and edit the init.rc to change the bootclasspath and match it with the port one" which is what iv done but also got stuck in a bootloop, looking at the two kernels are are a few differences in them. I think that might be they key.

Yeah, i know for the kernel, without being able to mess with the zimage, the sense max kernel lacks the init.environ.rc from gpe, the fstab file is different(at least file extension), and there's a few things that point to sense files or folders that don't exist on gpe. Currently there is no released source for the max yet :'( so unless someone knows how to do it manually and hasn't shared HOW to do so, I just have to wait.. Hopefully it won't be too long.

Is there such a guide/tutorial/description?
I am interested in porting ROMs to the G1. I am a total beginner, and I could not find anything useful (except the automatic porting of dsixda's kitchen, what is great btw, but I want to learn how to do it by hand, etc).
Could please someone tell me how to do this, what to copy from original ROM for things to work, etc?
Thank you very much!
It's going to vary from ROM to ROM, depending on what device you are porting from and whether it's Sense/AOSP/etc.
You can get some ideas from a couple of my posts though.

Porting is not generally that hard to do... It's getting everything to work right that's a pain.
Also, look at vendor trees for your device. That will give you a good idea about which proprietary files (drivers, etc.) that need to be replaced.

This is really great, thanks Gnarlyc... been searching all over for tutorials/etc. I was able to port an N1 ROM to the EVO (using dsixda's kitchen); however sensors + radios failed to work after boot-up; probably missed a couple files/libs. Will look these links for tips. Thanks!

really nice, finaly a topic where i found more infos than just "use the kitchen and change kernel"
other questions :
how do you know you needed to replace some string values by other ? simply open the original rom for you device and compare, or simply guessing the name ???
Hello XDA-members,
Today I've tried to port over a Evo 3D CDMA rom to the GSM version, with succes! It really isn't that hard. The first thing I wanted to know is what files are acually different in those 2 versions. It seemed the warm team already figured that out, thanks guys!! Then I took a look at this rom, as it is a hybrid for the CDMA & GSM version.
In that zip file you will find a folder called "devices" this folder contains 2 more folders "shooter" & "shooteru". What I did was look at the files in the folder "shooter", find those files in a sense 3.0 rom(as I wanted to port Android Revolution) I used LeeDroid for this, and then simply replace all the files that I needed to. With as result a working CDMA rom on my GSM phone!
Now it's not fully working, for example it fails to find my wpa2 wifi network.. calling works though! (it did the first boot, 2nd boot it didn't get any signal or I didn't wait long enough) The rom is responsive and pretty fast! Now I don't know if this has been done before, but I would like to tell you guys it's pretty easy to port a rom from the CDMA version to the GSM, of course it still needs a lot of work.
I'm currently uploading the rom for the ones that want to try it out, I've removed some sprint crap as we can't use it anyway..
Please bare in mind I only replaced some files in the Android Revolution rom with files from Leedroid, All credits go to them!
Also the rom is not fully working as far as I know, flash at your own risk.

Congratulations on porting from CDMA to GSM! Hopefully you'll be able to fix the issue and have a lot of the CDMA ROMs on the GSM.
You should check out this guide which should probably get more stuff working: http://forum.xda-developers.com/showthread.php?t=1222746

It's not that hard though, I'm also trying to get people to get more roms to the GSM version.
Also, no offense but that tutorial is aimed at porting sense from 1 device to another, but the shooter & shooteru are basically the same.. it's more the applications in the rom that need to be replaced I think. Applications like settings (so you can set your APN's) remove the CDMA compass thingy in the status bar etc. Because most stuff seemed to be working, camera worked both 2D & 3D, hw acc, wifi(only no wpa2 =( ), calls work, buttons work, etc.

GREAT! I was thinking about that today when I have came across this ROM http://forum.xda-developers.com/showthread.php?t=1277431 it should be some superb ROM but only CDMA, they have Sense 3.0 & 3.5 versions.... do you think that you can quickly look on the 3.5 version? you know, just breaf look to see if it will be possible to push it into GSM...

Awesome work! You should create a new thread in the dev section to list all successfully ported ROMs.
But be careful, some devs might not be that grateful to see they work ported. So you should ask for permission first.
Xda is a heartless cold place these days .

I wish to start porting ICS to my phone. That's my goal. I have general understanding of how linux works, but I do not know much about the android specifics of how they work, or what needs to be modified for this to work. I do not plan to use the kitchen tool as I wish to learn this the hard way. I believe this will help me become more understanding in what I am doing. However, at this point I don't and that's why I'm here. My phone model is irrelevant almost because its prepaid and usually the communities don't even recognize their existence.. at least that's how I feel about it. But I digress. My phone is the zte warp by boost mobile and I am here to learn hopefully the things that will get me started on porting ICS to this phone. I right now believe that the best thing for me to learn is how the android related files work because as it is, I only looked at guides on how linux works and I understand most of it. I'm not sure that's the best thing that will help me port ics, but I'm certain it is important.

From my limited knowledge, I think it is a huge task undertaking, you can download Android source code from Google, the hard part will be the device driver development and porting for Linux kernel (and maybe portion of Android). If you are lucky, you can use the existing phone bootloader (or you have to port one). Understanding the inner of the phone (different chip set may need different device driver) will be another challenging task.
by the device driver development, you mean all the libs that go into the phone? Couldn't I just copy/paste the pre-existing libs that are already made for the phone? Also the phone im working with is a bit strange really.. noone has been able to compile the kernel from its source and get it to boot yet.. when it was compiled the zImage was different than that of the stock one.
And yeah, I have downloaded the aosp source.. I just need to know where to start at and the processes involved really

To answer you question no the drivers and lib files are different for aosp based rooms then they are for the stock OEM from. The first step will be to get a working kernel. Without anything you do will be pointless
I'm somewhat interested in the same thing, and from what I've gathered, you'll need to do these things to begin ROM development:
1. Read every page on the AOSP site and grab a copy of the AOSP source. It probably wouldn't hurt to read the regular Android developer wiki as well.
2. Learn about Linux driver development:
http://lwn.net/Kernel/LDD3/ (this is apparently considered THE BOOK on Linux driver development)
http://www.freesoftwaremagazine.com/articles/drivers_linux
3. Learn pretty much every detail about your phone and its hardware, especially when it comes to how ROMs are installed on it. For example, my phone (the Droid X2) has a locked bootloader, so 2nd init has to be used to boot new ROMs, and this makes it so that we cannot update the kernel.
You can usually find this sort of information on your phone manufacturer's website. Sometimes they even post the source code to their phone's drivers, which is helpful.
4. Look at other ROMs (preferably for your phone) and see how they work. The source code is freely available for most popular ROMs.
For example: CyanogenMod keeps their source code in a public git repository: https://github.com/cyanogenmod
5. Get to work on porting!
I would highly recommend starting with something smaller, however, just as a start. One good jumping-off point is probably this guide: http://forum.xda-developers.com/showthread.php?t=1272270
If any part of this was wrong, or if I left something out, somebody feel free to correct me, I'm still a noob.
Thank you so much for your direction, however,, android kitchen.. im not sure about that because isnt that only ment for htc devices? My phone is made by zte
what device do you even have?
if it's stuck officialy on 2.1 or 2.2 there's no hope that if you even port it that it'll work
its the zte warp from boost mobile (prepaid). Btw if I compile an aosp ics launcher and put that on my phone whats the chances of that working?
edit: it uses 2.3.5
Well Sebastian responded on android forums, apparently zte is very bad at version control with their kernel sources. So when they complete one project, they use the same source for the next project, and what they release could be for anything. Apparently the blade source had the same issues, it took him a while to get them to correct the source

Yeah I noticed that there were ppl saying there were things similar but I'm not sure what will work or what won't.. guess its time to start a petition on zte to release the source code lol
edit: seems like zte's bein a bad company and violated the GNU GPL license for not providing a complete source code.. I compiled an email and sent it to someone who can proof read it and send it to the right person for this kinda thing.. danggit zte
Hi all,
i want to start with AOSP 4.2 for our SGS3 i9300 - is anybody interested to develop and publish a AOSP based rom with me?
I'm a real application developer (C,C++,JAVA,PHP,MySQL,some Oracle PLSQL) and now its some cold out - i have time to do
some nice things
I think a team of 2 or 3 developers should be enough to develop on this rom, as we can use a lot from AOSP 4.1.2
### EDIT
As long as no one has found to help, here a short description of current progress:
- Code is pure based on AOSP 4.2 but some snippets of CyanogenMod to bring up hardware (camera,graphics,audio)
- Device is bootable (no other boot.img required anymore)
- Bootanimation is working
- Mount of partitions is working
- Deodexing is working
- adb, debuggerd and root access is working
Not working: a lot
- Graphic not working perfect, needs a kernel patch or a working gralloc/hwcomposer/hwconverter to work without laggy PMEM)
- Camera can not be activated due to a missing function call (undefined reference, maybe it can be solved with a newer driver)
- Audio: missing speaker device (Code have to reworked to work with stagefright and tinyalsa libs)
- USB/internal SDCard: cant be mounted (error message sounds like the device is mounted twice, have to find the error in init process)
- RIL not working (Java file from CM10 have to be integrated in frameworks/opt/telephony)
Currently, i'm working on the Graphic problem and USB part to bring up the device to a stable UI
Way to go man. Good luck to you!
Good luck ...!! Im waiting

Good evening,
Well how have you imagined that? Do you have build something like that before or would this be your first attempts to build up a rom from scratch? Do you know what's all necessary to contribute for that?
I would try to help you, but I have clearly to say that I haven't done anything like this before. I'm in the last term of my study of technical computer sciences, working in a company as application programmer for C/C++ and Java(Android). Due to my studies I have also some knowledge about hardware programming, down to read/writing some code in assembler. I would be interested to this if I get introduced to the topic and some help with the necessary tool chain wouldn't hurt too ^^.
greetings

I have successfully built a rom in year 2010 for the LG-P500 device, based on CM7 and modified it in a strange way, so i included a lot of nice things
written from scratch - this rom was a unicate ... later, i developed the "Phoenix Launcher" for Gingerbread enabled devices, but its development is currently
frozen because its strange to support every or almost every device with a bugless launcher. In the last months i learned a lot about android and have to re-think about
what i'm able to do, and what i want to do. In the summer of 2011 i bought my SGS3, the first thing i was doing was to remove that samsung crap from my device and
have installed AOKP. So now it's time to do my own thing again - i want to have AOSP as i think for me its the best Android solution for myself and want to publish it
to other users who think "thats ok for me" too
In short, it doesnt matter if its your first rom - its enough if you know about basic things like "how is android doing all that nice things", "how to debug code", "how to fix
some bugs (even strange bugs)" and some experience with git and github. All other you can learn in a very short time - i've learned the most of things with try & error

This all sounds interesting for me and yes I like the idea of developing a own clean rom with some cool additional stuff, too. But what would be the first steps to a new rom? Have you begun with all the administration stuff like setting up a new gitrepo, make a to do list etc...?
I think Code debugging and writing some new stuff wouldn't be a problem for me but what are you meaning excactly with "how is android doing all that nice things"? How it build up, deep level architecture? Well, I know how the "normal" Linux system is working, how modules are getting loaded into the kernel... But how this is correctly working on android I have to learn at first and if there is a chance to do that I would do it
Currently on my S3 is SlimBean and till that there is still no update to 4.2 I'm happy with it, but exploring something new would be pretty cool
Do you have an IRC chat room or something like that? I've to go offline now, my girlfriend wants more attention.^^ But If you want, I' m willing to try to contribute to the rom
PS. I'm sorry for my bad English and hope its understandable, but outside from here you can talk to me in German ^^
If you want to help the AOSP experience on our phones the best place to do it is with the CyanogenMod guys. You'll find pretty much everything based on AOSP (including people that port Vanilla AOSP and AOKP) is using a CM kernel.
They're likely working on the merge now in terms of getting CM10.1 out (with Android 4.2) but most of our CM guys are pretty burned out on working with Samsung's subpar reference material to get basic stuff working (mostly HWC). If you think you could help with this, this would be provide a massive boost to the whole community that want to run these phones on an AOSP based ROM and they would be very grateful.
Gotta warn you though it sounds like it'll be an uphill struggle to get the rest of the stuff working right; unless Samsung release some decent sources for HWC.
Currently i have only downloaded the AOSP sources and started to integrate most of the configs. Currently it cant compile because AOSP is not AOKP/CM10
where i got the device and vendor directories, so i have to make some changes in the basic system. if it's compiling to the end, i open a fresh github account
and upload all my modifications. The compile process stops currently on audio,OMX plugins, graphics and camera - most of that are small pieces of changes
i have to make - i think, tomorrow (its monday in germany here) i can upload all and then we can start to develop on

Wish i could help (just started learning JAVA ) ! gl with this awesome project
Nice to see you here, I remember you from the P500 forums.
Xda user krarvind should be able to give you some useful hints, you will have to contact him through the RD forum as his pm is locked down, or I could possibly put him in contact with you

How it's going forward?
Maybe it could be useful to publish the github link when it's ready and some more information like staus, on first post
In the next days I have some trouble with my exams ( in two weeks I'm completely finished with my studies ^^) but I think if there is something to do I'll find some time to work on.
Good Luck Dude~
I haven't tried AOSP yet.
Hope someday i can give it a go.:silly:

current state:
- patched android/build so we can compile the kernel within the main compile process
- patched android/build main.mk file so we can use OpenJDK or Oracle JDK
- added android/vendor/aokp and android/vendor/samsung tree from AOKP (its the most useful directory structure)
- added android/hardware from AOKP so we have all that Exynos things that are needed, even by AOSP
- modified android/frameworks/native/include so a OMX Plugin header can be found
- modified android/libhardware and patched gralloc module
currently it compiles to the Webkit library, most of all apps, libs and binaries are building without errors - the next problem
to solve is the PRODUCT_COPY_FILES ****: nothing of proprietary files are copied to the android/out directory, seems like
a bug in android/build too.
For only 2 days trying to compile to the end without errors its a very good cut
here we go: it compiles to the end and a flashable "JOP40" zip could be created
tryed to flash, but it gives errors in CWM: have to remove the recovery folder and the recovery.sh file from etc folder in the ota zip file, but it doesnt boot up - got a black screen only.
do we need a new or patched kernel instead the CM10 smdk421x one?
Well does it have all the closed source libraries fron the phone? If not, it wont boot. Dont think i am calling you stupid, you obviously know what you are doing, but maybe you forgot. Idk. Check that. Try running a log cat and debug that.

Thanks for the hint, yes i have all files included - i cant connect to adb, i see only small colored point on the top left side and a sensor
is red blinking (the one to the right of the speaker.
That would be the proximity sensor near the top front speaker. Cant connect, adb binary in /system/bin or xbin?

Hi all,
With the risk of this being called a duplicate thread I just want to clarify that I'm in no way asking to port something for me, and I've read the 2 similar threads around, and felt like this should have it's own place.
So, straight to the point, I've been looking to get involved with android porting, and since LOS and AOKP for our device haven't quite filled my cup I was thinking of trying to port something else (trying to not get into much detail here )
Moving on, after searching around XDA and everywhere else, I've found a tuto or two where the process of porting was explained, and being an average user, I went to grab a "Base ROM", (thought the LOS/Stock ones would do, downloaded both)
To my surprise, files mentioned in the tutorials (framework-res.apk, framework.jar, ...) are nowhere to be found.
Finally the question, this just to save me from a reflash,
Am I supposed to install the "Base ROM" to dump /system to my PC?
Or am I perhaps misunderstanding something?
----
PSA: I'll probably find it difficult to get time to work on this (school stuffs) so even if I decide to go on with it, it might take a good while till something comes up.
Also, if there's someone with some experience in porting who'd be so kind to give me some pointers or show some availability to help with bug fixing/porting (not asking for labor, just explanations, in case I need 'em), please PM
Thanks, and sorry for the long post

i wouldnt even try to port, its just confusing, files missing, preloader updates which makes you think which one to use, its all really just a mess, you will have better chance of getting something if you build from source, just fork our device, kernel and vendor trees and download a custom rom source of your choosing and build it, i wont say step by step, but i recommend that to download the vendor, device and kernel sources you make the local_manifest.xml so that when you do repo sync it downloads those sources aswell
