[How To] [GSM] Getting started with porting

Ok, so after having a million questions I thought I'd write up a quick little 'how to' with regards to porting.
And now the warning
Read and learn first, doing this could cause serious issues with your tab or even brick it. The tab is really tough, and hard to brick if you do everthing right but it could still happen. I'm not responsible if it does.
Where to start
Get good at reading, google searching and searching XDA. Lots of porting discussion regarding other phones can apply to the tab.
Learn to use Heimdell
Have a linux distro available, either by virtual box, or natively.
Technomancer where it all began
I've said it before and I'll say it again, without techs work miui wouldn't have been possible.
Reference technomancers thread here: http://forum.xda-developers.com/showthread.php?t=931857 on how to download the cm7 + sgt source, you're also going to want to follow the kernel making part, cause most likely you'll need to make adjustments to the init.rc which is inside the initramfs and requires building the kernel again.
porting x build
Get X build onto your computer and extract the update.zip for it.
Copy the boot.img into your linux environment and extract it using splitbootimg.pl script (note: Google it, plus this doesn't work with samsung builds). Compare the init.rc to your init.rc (from the sgt cm7 kernel source root folder). Specifically the most important part here is the PATH, LD_LIBRARY_PATH statement and BOOTCLASSPATH lines.
Build your kernel with the updated init.rc and flash with heimdell, it should still boot your cm7/miui build (if you were running it before) albeit with errors.
The system
Now following the awesome list of proprietary files (either from your source folder or technomancers github link) check the galaxytab-common-vendor-blobs.mk for the GT-P1000. It lists every file you need that's propreitary to the tab and where to put it.
Also you'll probably need the debuggerd from /system/bin on the cm7 build.
Compare the /system/build.prop of the cm7 build to your port, make sure the ril info is the same as well as the ro; model, brand, device, board, and platform lines.
Create an update.zip (or whatever you want to call it.zip) and try it.
It's not booting
Logcat is great, but I really suggest using the ddms from the android sdk tools. It's color coded, and gives a much nicer view of what's happening.
Using winmerge in windows or a linux file compare program start checking what other bin files may be missing that you require. Special notice to the xbin folder.
It works! I want to post it!
Ok, first up, make sure you have permission if this is someone elses custom build you've ported. Most people/groups are really good about it assuming you ask first and give them credit in your post.
Also credit everyone who helped, answered a question or sent you in the right direction. (it's just polite)
Second your going to want to make sure your update.zip flashes the kernel, read the update_script from the cm7 build to understand how it works.
So that's it for a start. roll up your sleves, gather your courage and get to it!
Please if you have other tips, add them to the thread, what's better 1 or 2 'developers/porters' or 100?

Thanks. This is very useful for me.

Thanks,
Following this method, with slight alterations to adjust, I was able to port an i9000 phone build to the tab in about 10 minutes, it's really not terribly that difficult once you have the right steps.
The first couple times are usually frustrating but after that you get the hang of it

Hi mssmison Thank you for your guide,it will be very useful in the future! I have only one request,how can I contact you? I have a proposal for you about a dev team (regarding an old think tank)

Thanks for the guide...
Is there any ROM left to port by the way?

[Hot!] Wanna Be a Developer AkA Cook ?

I know nothing much of ROM Development but I do have the basic foundation knowledge and I wish to commence in releasing a modded ROM soon as a start...
As a start can anyone give a pointer of the following :
1. Boot image » what is required to extract / modify ?
Note : Please do not re-quote as I will be making changes as we go along
So let us discuss and explore so that we can learn together....

I was thinking of doing the same andy. Asked cow to see if he would like to point me in the right direction.
I had to abandon my idea as new house i moved into i dont have any internet to work off so had to put my plans on hold. But here is what i was told what is basically needed for cooking roms.
1) Download Kitchen:
http://forum.xda-developers.com/showthread.php?t=633246
2) Download your stock ROM
3) Extract system.img.ext4, cache.img.ext4 and boot.img from stock ROM, put into Kitchen's original_rom folder
4) Do this for SGW: http://forum.xda-developers.com/show...8&postcount=12
- No need to upse KezzaPlane's updater script anymore
5) Run ./menu in kitchen and follow the instructions
On part 3. If you want to use a different kernal( Oc one or simply Cow's oc kernal) please make sure to ask for the use of the kernal first and then use that boot.img and replace it into the rom that you are going to cook.

hi, thank you very much for the information, so far i have downloaded eclipse ee, and the android sdk but had zero idea where to start lol
i was so motivated when arco started and released his ics rom that i wanted to do my share as well, i have experience in coding in java but also wanted to know what else to do, then i bumped on this post, thanks a lot man!

Camera not working on 4.1.1. AOSP VZW full_toro ROM

Please accept my apologies if this has been answered before. I did a search and did not find a similar problem. I am a noob and will read any guide or how to that you refer me to in order to learn how to get better. I am new to Ubuntu/Linux and terminal but if you point me in the right direction I can probably figure it out. I will try to provide as much detail as possible.
I have recently built a Jelly Bean AOSP ROM following this XDA Guide.
I am using Ubuntu 10.04 LTS x64.
repo synced with this branch
$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.1.1_r3
which is build JRO03H
I downloaded and extracted the binaries on the Nexus Binairies page. I did notice that prior to building that unlike the ICS branches the JB device/samsung/toro folders do not have a extract-files.sh file
I made an otapackage using the full_toro-userdebug command.
I flashed the rom using ClockworkMod 6.0.1.0. I did a factory reset and wiped the cache prior to flashing. I also installed gapps-jb-20120726. Everything booted up fine and for the most part everything works except for the camera app. When I press the camera button I receive a message that says "Unfortunately, Gallery has stopped working." Or I get a black screen and nothing happens then I'm back in the app drawer. I have tried fixing the permissions and that did not fix the problem.
Can you explain to me what I need to do to get my camera and gallery app working? This is the only issue I have with my rom thus far. Do I need to extract the camera binary some how?
The camera and everything works fine my AOSP IMM76L build but not with my JB Build.
I have flashed other roms such Peter Alfonso's JB rom and his camera works fine, so any directions or links would be greatly appreciated.

Seeing the same.
I have this same JRO03H build (except I use CentOS 6.3 to compile AOSP 4.1.1_r3) with the EXACT same issue you describe. When the camera applet is selected it complains "Unfortunately, Gallery has stopped". Everything else in the build (24hours+ fresh) appears okay so far.

I fixed it.
I figured out the problem and was able to get the camera and everything to work. I did a couple of searches on Google and came across a thread from Android Central. I cant post the link since I have less than 10 post, but pm and I will send it to you.
We are still missing some proprietary files. Namely 6. The camera is named ducati or something and you have to either get it from another rom or extract it from ICS. I personally used Peter Alfonso's github for Jelly Bean and compared his vendor folder to mine and copied lines from his make files. Took me a couple of hours of comparing every file to realize that you need to focus on vendor some other files in core folder.
You can get his github information from his webpage and also look inside his OTA compared to your OTA to make it work. Also if you want to use Google Wallet you are going to have to edit your build.prop file in your OTA to make it not say full_toro use the 4.0.4 release keys.
I'm not at my testbox to walkthrough the steps but that's what I did. But sure to backup your source folder before you start tweaking, Came in handy twice before I got it right.
Hope that helps. Good luck.

could you please share your Rom? I also have the same issue. but still not fix it.

[MOD] NFC with Screen Locked/Off CM10, 10.1 & 10.2

I haven't posted enough on XDA to be able to reply to the appropriate development forum post, so I decided to post here. I'm running CM10 on a Sprint Galaxy Nexus (toroplus), and I had been in need of a way to use NFC while the screen was locked, but couldn't find one for the latest build of CM10. I found this thread http://forum.xda-developers.com/showthread.php?t=1709586 but the latest updates only had one for screen off (which is a little less secure IMHO), and when I used it, I would have to turn NFC off and then back on almost every time I used it, which defeated the purpose. I also saw that someone else was having the same issue, so I decided to compile one myself using the latest CM10 source. This was built from source as of 10/31/2012 and has only been tested on the nightly build with the same date. I figured I'd share it with everyone that might be needing the same.
Disclaimers: This requires a rooted phone! This has only been tested on the Sprint Galaxy Nexus running CM10 nightly dated 10/31/2012, but may work with other versions. Do a backup! I'm not responsible for any problems resulting from these files, so backup first!
To install, copy to your SD card. Reboot into recovery. DO A BACKUP! Install the zip from the SD Card. Reboot.
There are two versions I created. One is for when the screen is on, but locked. The other is for when the screen is off.
Update 1/2/2013:
I compiled a version of the screen locked for CM10.1 (Android v4.2.1) for anyone who would like it. I was getting mixed results with the previous file on 10.1. This one is working on my toroplus with the latest CM10.1 nightly. I'll build a screen off version later. I was having some problems with my build VM, so I didn't get to it yet. The new file for CM10.1 is called NFC_Screen_Locked_CM10.1.zip.
Update 1/3/2013:
The CM10.1 version of the screen off version is now posted. File name is NFC_Screen_Off_CM10.1.zip
Update 1/16/2013:
Previous version of NFC_Screen_Off_CM10.1.zip was not working. Should be working now.
Update 1/16/2013:
Added a patch that can be used against CM10 or 10.1 source code to add an option to the settings to switch between screen on, locked, or off NFC. You must build the entire thing from scratch to use this patch. There are logs of guides for building CM. Here's a link to the CM wiki article for toroplus for example. Before executing brunch, copy this file to the root of where you created the repo (the article uses the ~/android/system/ folder for instance) then execute the following two commands:
Code:
tar -xzf nfc-patch.tar.gz
./apply-nfc-patch.sh
Or in the use package manager to untar all of the files (maintaining the directory structure) and then double click and run the apply-nfc-patch.sh file. This will patch all of the necessary files in the build. Then continue with the instructions in the build guide and flash the resulting ROM.
Disclaimer Again: This could break your phone. I'm not responsible for any damages this may cause. This has only been briefly tested on my toroplus with the latest CM10.1 code from the repository.
Credits: Rick C who originally submitted most of this to the CM repository but was rejected.
Update 1/21/2013:
Looks like a recent commit to the repository broke one of the diffs in the patch. Uploaded a new version.
Update 2/13/2013:
Another update to fix an issue with the patch files. I also added a reset script that will do a hard reset for git repos of the affected packages. Don't use this script if you have made any other customizations to the Settings app, NFC app or the frameworks/base code as you will lose them. Just do things in this order:
1) run reset script
2) run repo sync
3) extract tar again
4) run apply script
5) run brunch again
You can use this sequence every time you want to grab the latest code.
If you get errors when running the apply script you can use this command to delete the error files that come up. These files might show up even if the patch works, but the code wasn't exactly what the patch was expecting, but enough to apply anyway.
Code:
find . \( -name \*.orig -o -name \*.rej \) -delete
This set of commands should do the trick for most people to get the latest code, apply the patch and build:
Code:
./reset-nfc-patch-repos.sh
repo sync
tar -xzf nfc-patch.tar.gz
./apply-nfc-patch.sh
source build/envsetup.sh && brunch <your-device-name>
Update 2/27/2013:
Made some fixes to the notes in the previous update based on feedback from mrplowdan.
Update 3/15/2013:
Compiled a new version of the CM10.1 files for those having issues.
Update 10/21/2013:
Added a test version of the screen locked version for CM10.2 now that toroplus has an official CM10.2 nightly. Let me know if there are any issues. I'll add a screen off version when I have some time.
Update 11/19/2013:
Finally getting around to adding a screen off version for CM10.2. The screen locked version has been running well on my toroplus for the last month with no issues.

Has anyone tested this on Maguro?

Just recently got my phone back from service (after 10 weeks) so i'm not re-rooted yet, hence i can not try this on stock myself. Just wanted to give a big thanks to you for creating and developing this this is really a truly great way to make use of the nfc and the way it should have been done from the very beginning. I.ex if your out running, listening to music and for some reason need to pause your music, just swipe a previosly attached nfc-tag on your sleve over your pocket with the phone in. And again to start music. Awsome work, thank you!

It may work on Maguro as long as you're using a fairly recent version of CM10. If I knew anyone with a device, I'd test it myself. It's fairly low risk to test. It only replaces a single file. It's the Nfc.apk in the /system/app/ folder. You could always rename your existing file; install this one; and then reboot and test it out. Also, if you're wary of the zip itself, you can just extract the Nfc.apk and copy it to your /system/app/ folder manually, just don't forget to reboot. Then if it breaks you can just delete the new one and rename the old one back. You could also just backup everything; install the zip; and just restore the backup if anything breaks. Anyway if you decide to be adventurous, let us know how it goes. I'll keep this thread updated if CM makes any other changes that break it again. I use it often, so I'll likely find out pretty quickly. Hopefully, they'll add this as a setting in CM10 some day.

could i use it on every rom cm based?

It depends on how many modifications were made by the mod around NFC, if any. Also depends on when the last time was that they merged their code with CM. In theory it should work with most CM based mods. You can always try it out as I mentioned above and revert if it breaks. And post here with your results if you try it, so others can benefit.

CM10.1 Update

Best regards

can it be included in cm10.1?
I was just wondering, can't this be somehow merged with stock cm10.1? Add checkboxes in the settings.apk, lots of warnings when enabling it and people who know can use it.
nice work btw

Screen Off for CM10.1

Yes, actually I've been wanting to do this for a while, but I never seem to have the time to dig into the settings UI and how to read that setting. If you or someone else would be willing to create the settings piece and tell me how to access the setting that you create, I'd be happy to alter the NFC service to look at those settings. Ideally there should be a preference with an integer value of 1 for screen off, 2 for screen on but locked, and 3 for screen on and unlocked (default) as that's the value that the service expects currently.

First of all i would like to thank you posting this, just what I was looking for.
Im running one of the latest cm10.1 nightlies (jan 1st or 2nd) and flashed the NFC_Screen_off_CM10.1zip however it doesn't work while the screen is off, though it does work when the screen is on and the phone is locked. I have a Galaxy Nexus (gsm).
When I logcat the phone I don't see NFC being discovered with the screen of but with the screen on and the phone locked I do see that it discovers an NFC event.
Is there anything that can be done about this?
Thanks!

That's odd. I didn't have an NFC tag handy when I built the screen off version, so I assumed the same changes I made in CM10 would work in 10.1 since the screen locked version worked. I'll test it on my device and see if I can figure it out as soon as I get some free time. Thanks for letting me know!

I decided to check the files out myself to try and figure it out and maybe quick fix it myself (which would have saved you the time) by referencing to the 10.0 apk's however I found out they differ a lot more from eachother than I expected so it was a bit too much for my skillz. I found this out using a comparison tool and while I was at it I compared the 10.1 screen lock and 10.1 screen off versions. According to my program they are exactly identical in either file structure as in file contents so I'm guessing something must have gone wrong with renaming or I just don't know how to use the tool? I'm just mentioning this as something I came upon, not to ***** or anything! I really appreciate the work you did!
Anyway.. I had some fun figuring things out and learning about decoding apk's and all of that. Thanks for all the hard word so far and I'll just wait patiently upon the new screen-off version.

The screen off one works perfectly for the Toro running the last stable 4.1.2 liquid smooth rom. Awesome work, thanks a million!
Edit: I'm not sure if it makes a difference but I didn't flash it, I pulled the apk from the zip, copied and pasted and reset permissions then restarted.

I did a little digging and found that there was a patch submitted to CM10 to include a switch for this in the settings. However, it was rejected by Steve Kondik and abandoned. I took all of the code and merged it into the latest CM10.1 code and it seems to work. I added a patch to the main post, but you have to compile CM from scratch to use it since it touches some framework components. The good news is it should work on any device that CM supports (that uses the NFC.apk though not devices that use NfcNci.apk like the Nexus 4) and should work on both CM10 and 10.1 in most cases.
The patch is basically just a few diff files and a bash script to automate the patching. If anyone is feeling adventurous, feel free to experiment with it. I can't promise it will work for you, but it's fun to try and learn a bit about building CM source code in the process. Basic directions are in the original post. As always I take no responsibility for anything it might break, but I'll be happy to try to troubleshoot if I can. Enjoy!

Thanks for all your effort.
Unfortunately it doesn't work on the nexus 4 but after some googling I found a working version for the nexus 4 on the forums here on xda. Im guessing there's a difference in chips or something...

Thanks for pointing that out. I clarified the previous post a bit. I should have said it should work with any devices that use Nfc.apk. Newer devices that use NfcNci.apk will not work with the patch.

I need a smart Dev to dummy something down for me...

I have been in love with all things Android for years but there is a certain level of proficiency that I don't think I'll ever reach. I'm reaching out to anyone who can provide me with some assistance in this issue. I have a Nexus (my wife's) that constantly crashes the Talk and Camera apps. I've tried dozens of solutions posted online but I think the only one that actually addresses my issue is provided in the link below. Unfortunately, when it comes to compiling Android source code I get in over my head.
Could someone please give me instructions on how to implement this fix? I would like to run AOKP JB Milestone 1. It appears I need to swap out the binaries before compiling and flashing this ROM but that's about as much as I can tell.
Please help!
Link describing the fix -------------> http://anders.com/cms/435

Is there a reason you don't just flash the aokp rom that is already compiled? You do need to get some of the closed source proprietary files if you are compiling yourself (though I would have thought that aokp would already have everything set up in a vendor folder for your device). Talk is not part of aosp and you should be able to get it working by flashing a gapps package. It sounds like you are missing the talk libs (.so file) that goes in /system/lib. Look for libgtalk_initial.so and libgalk_stabilize.so. For the camera, make sure you have the ducati-m3.bin in /system/vendor/firmware. You can get these files from the factory images provided by Google or download a stock rom.
If you are compiling source yourself, the easiest way to see if anything is missing is to extract the factory image or a stock rom and use a program like beyondcompare to see the differences between your rom and one from Google.

See, this is where I'm confused. I'm not compiling the ROMs or any of the gapps myself. I'm flashing a copy of AOKP that I used on other nexus devices and had zero issues. For some reason this phone won't work quite right. I've wiped, clear data, fixed permissions, blah blah blah.
From hefty googling I have found a decent number of other threads with my exact problem but none of the threads actually have a solution.
