[Q] [ROM][PORTING] - External SD Card and other anomalies, advice welcome. - AT&T LG Optimus G

Anyone that has ported a few roms before, specifcally from a similar architecture, in this case from another Qualcomm Snapdragon S4 to our LGOG from Nexus4 and Nexus7 (2013) {edit. or GalaxyS3}. They are both spot on as far as similar but for the life of me every generic porting guide is written with great intentions and horrible follow-through.
What files for our device specifically control each part of our phone in the ROM .Zip? Especially for External SD working, and anything else off hand you feel like mentioning from experience.
Lastly, any differences porting from 4.2.2 to 4.2.2 vs 4.3 to 4.3?
Thank you in advance.
I've been trying push illusion rom over from the nexus 4 source, after 10+ mostly working attempts I started changing multiple variables at once, purposely dirty flashing over slim-bean because it left some residual files, removing the format /sdcard part from the updater-script of illusion to piggy back off of slim. Somewhere in the midst of this I actually had the External SD show up in storage settings, FINALLY. But by that point I started getting lots of FC's on the launchers and just about every app. Prior to that my main bug was that I couldn't control brightness, it was stuck on 100%. Somewhere in the middle of screwing with fstab's and the 4.2 exfat patch I could read the external card from the symlinks but it wouldn't show under storage or MTP/USB, only internal.
I'm going to have another go from 4.3 base to 4.3 from scratch. Feel free to chime in with anything.

It is fairly easy to go from n4 device repo to our repo. If you want to see what others do, just look at someone else's Repo's. I have my tree for aosp here, which is a basic n4 -> lgog fix, with a few hacks for unsupported things in aosp like button backlights: https://github.com/jbott/aosp_android_device_lge_geeb_att_us/commits/jb-mr2-dev
Not the cleanest thing, but shows what basically needs to be done.
I find dvhexer also keeps fairly clean repos that are easy to follow, if you want to check his out.
EDIT: Now I see that you mean literal porting directly. I would recommend building from scratch, even from a device as similar as the n4. It is not hard to do once you understand the basics. I actually find it is often easier than porting manually because the source layout makes sense. I believe the sdcard / mtp stuff is in framework-res as storage_list.xml though. It should match that in the overlay directory of my repo to work correctly.

I agree, I actually like reading through the source, and I have a good copy of ubuntu plus vm software, or I could dual boot, but unless you have explicit instructions on how to download the absolute minimum amount of data to compile from two different sources, I don't want to attempt it with this free hotel wifi. As it stands now I have more than one wifi card connected at the same time and a python script always running in the background changing the metric for my adapters, as each connection is limited to about 97KB/sec.
Does git know to sync across multiple interfaces? might not be too bad if it does.
Otherwise thanks for the link, reading that side by side with the MAKO source from googlesource.com you are correct about the location in frameworks. I'm pretty sure I can split that apart with an APK explorer and make the adjustments without breaking the rest of the rom(s).

Android 3.0 Honeycomb Preview Image v04 - 2/7/2011

First of all I have to thank the CM people, especially mbm, nemith, fattire and cvpcs for their work on gingerbread which helped me a lot in understanding where to look and what to patch.
The whole thing is based on the honeycomb preview emulator images, some of the B&N modules+driver, pieces from the upcoming CM7 and manual patching ARM assembler in libraries, writing ugly scripts to hack around various issues, a lot of time and many brain cells.
Use this on your own risk. I'm not responsible for any damages. This is not meant as a primetime ready rom. This is a preview after all.
The unzipped image is around 3.5gb and fits on 4GB SD cards.

Status
What works:
Graphics acceleration
Accelerometer
Wireless!
Touchscreen
Buttons
Sleep/Wakeup

Known issues:
The accelerometer behaves funky. Will try to fix this.
The Gallery app crashes when opening an image. Not my fault, it's broken in the emulator from google too.
Doesn't work:
DSP e.g. no hardware video decoding (and will possibly never work before the AOSP release)
FAQ
Q: Why?
A: I thought it would be fun. It was and still is. And now developers have an actual device to test their apps on instead of relying on the slow emulator.
Q: How?
A: I'm planning to write a blog post. Mostly learning how Android works, debugging, patching, reusing binaries from different sources, finding easy ways to reach a goal, try and error, a lot of brain power.
Q: During boot I get stuck at the Android screen with the blinking cursor.
A: It seems to be a timing issue with mounting the partitions. Sometimes rebooting helps to get it booting. If not a different SD card might to the trick.
Q: Why is there no Market app installed?
A: There's no legal way to distribute the google apps with a ROM.
Q: Angry Birds, Nook reader, Kindle app?
A: Yes.
Q: I want to port Honeycomb to device xyz... send me the instructions how to do that now!
A: I like the 'I' in that sentence - but there are no instructions, no source, no nothing. Learn and read about Android, Android porting, making custom roms, embedded systems, ARM assembly, driver programming, programming in general, the Linux Kernel and much more - and when you're comfortable and have experience with all of that come back and do your port.
Q: Can you port Honeycomb to device xyz?
A: I don't have xyz. And even if device xyz would magically appear at my front door doesn't necessarily mean I'll have the time and motivation to port anything to it.
Q: I want to use a different kernel what changes did you make in the kernel?
A: https://github.com/rbrune/nook_kernel
Q: Where can I donate?
A: I don't want any money. If you want to put your money to good use donate to a humanitarian organization and/or the EFF.

awesome, time to mess around with this.
Amazing work. I'm always impressed when people get an SDK image booting on a device and working properly, but this isn't even technically a tablet! It's an e-reader that was hacked. Unreal.
Keep up the good work.

right now that seems a bit (quite a bit) pre-mature, also honeycomb is definately destined for tablets (atleast the pre-release is) so even if you could it seems that it wouldnt run (see http://phandroid.com/2011/01/28/and...ator-shows-signs-of-smartphone-compatibility/ for more info)

If you take a look in the settings there are a lot of references to phone features but yes I do agree this is will more than likely start out on tablets and large screen phones

[Q] [q] will flashing a different kernel improve call quality?

I've done some researching through XDA and Google. And from what I can tell (unless I read wrong), that the EVO 3D's handset mic settings are built into the android kernel. With that said, is there a way to modify the stock kernel so that the mic settings can be adjusted to improve call quality? And if so, can one of the devs who specialize in kernels, take a look into it and create a fix?

the first step would be finding where in the kernel source the mic settings are "hard coded". finding the audio/sound drivers location and then the location for the mic would be a great starting point.
i don't have the source code in front of me, but grepping through it or looking thru the drivers directory would be where i'd start.
since you searched, which is very helpful, do you have any links to where in the kernel you read the handset mic settings are coded?
the more detailed information you can provide, the quicker a dev can pick it up and run!

I apologize, as I was in a hurry at work when I posted the topic... I meant to say android mic settings... not EVO 3D settings.. my bad.
Here are the links that I've found that made me conclude this theory:
1. This link is Android related - not EVO 3D based, but can it be applied to the 3D? - http://forum.xda-developers.com/archive/index.php/t-549837.html
2. This link is Nexus (which runs on Android) - not EVO 3D based, but are there any clues that can be applied to the 3D? The first paragraph does mention In-Call volume (and mic-sensitivity) and the author does mention that "(I now realise these 'stock' setting s are located within the Kernel)" http://androidaudiohacks.com/home/archives/121
3. This link mentions that Android communicates with the kernel, which then handles the hardware.. i.e. the kernel controlling the hardware - not EVO 3D, but is Android based - http://forum.ppcgeeks.com/android-tp2/141857-evil-mic-problems-devs-look-here-if-you-have-time.html#post2070440
4. This XDA thread - which appears to be an Android port running on a WinMo phone, LaTama mentions that the audio driver was in the kernel - http://forum.xda-developers.com/showthread.php?t=1162224
Another.. http://forum.xda-developers.com/archive/index.php/t-805002.html
5. This post - an Acer Liquid (Android based) although the user's English isn't very well - mentions that the mic sensitivity is too low with the custom kernel he (or she) just flashed - http://android.modaco.com/topic/338884-microphone-sensibility-too-low-with-custom-kernel/
6. This post - Cyanogen mod on HTC Dream/Magic (Android based) mentions some system files somewhere that enhanced the mic gain adjustmen http://http://forum.cyanogenmod.com/topic/7213-mic-gain-adjustment-60/
With these links that I've found so far, it makes me think that the kernel could be the solution to the call quality.
I did go to the dev section of HTC's site and download the kernel source for the EVO 3D, but I have no clue as to what I'm looking at, as I'm not a dev..

well, two basic approaches:
1)links 1, 2, and 6 all seem to point at the same set of files in /system/etc. might want to check if these are present on our evo 3d. if so, might want to look into editing/replacing them. they are xml so they should be readable thru a text editor and hopefully they use fairly english common sense related tags.
2)i decided to take the liberal of pointing around the online kernel source at the android git, since i cant access anything else at the moment-link below.
i grep'd the source for the word microphone and you can see some scattered references in the kernel files. this is the approach i would take to look for the microphone volume settings in the kernel drivers...
http://android.git.kernel.org/?p=kernel/linux-2.6.git&a=search&h=HEAD&st=grep&s=microphone
figured the more information we can gather, the better off we should be!
How would I go about to view these files?

the files mentioned in the above posts you linked are .xml files in /system/etc. easiest way for me is to adb pull them off the phone and then use a text editor ..
adb pull /system/etc/blahblah.xml c:\android\blahblah.xml
the kernel source files you downloaded, should all be text files and can be viewed in a text editor also...
good luck! keep us updated on what you find and i'll keep my eyes open as well!
When you do the adb pull commands, what status does my phone have to be in.. fastboot, recovery, etc..
Also, when the adb pulls the files, will they still be intact on the phone or does it "cut" them out of the system?

adb is going to be a great tool to learn. i wrote a simple guide for the evo - http://forum.xda-developers.com/showthread.php?t=694250 . there are probably lots of other guides too.
google's info on adb - http://developer.android.com/guide/developing/tools/adb.html
when you pull the file, they stay on the phone and adb duplicates it to your local computer. it is probably easiest if you're in the normal booted android mode and have usb debugging toggled on.
adb is going to be a primary way of communicating and modifying the phone. it'll become your best friend!

[CLOSED] Export Q Function to Any Android Device

Sorry Guys,
As there doesn't seem to be a whole lot of interest in this project and as no one stepped forward to assist, I'm afraid I'm going to have to abandon this project.
Thanks for following.
___________________________________
OK Guys,
I've run into a bit of a brick wall and need some input from other developers. One of the required APKs from the Q needs a class not included along with my CM9 or Samsung stock roms. The class appears to be called "android.os.UpdateLock". So how do I go about ripping the class out of the Nexus Q rom and injecting it into CM9? Any help would be very appreciated!$!
--------------------------------------------------------------------
Hello All,
The Project
I'm looking to embark on a project to rip out the cloud function from the Q and install it on any android device. I want the cloud streaming of "Google" music and movies without the $300 expense.
The Progress
As of today I have the Nexus Q Deodexed, ripped out several apk files including the Nexus Q "Launcher" HubBroker.apk. I've merged the apks along with the fonts and lib folders of /system and my Galaxy Tab now boots up and runs like a Q. Primary issue outstanding is, the Nexus Q app won't detect the "galaxy Q" through bluetooth. I assume that some functions of the Q are sitting either within the bluetooth libs or that the Nexus Q has a specific bluetooth address that the app needs to see before detection.
My next attempt will be to try taking apart the Nexus Q apk and either changing its bluetooth search criteria or removing it completely. Second to that if anyone out there has a Q and has it setup on their phone, I could use the /data/data folder to extract more information about how it works. Or even better if someone knows what config file is generated on the actual nexus Q when it's set up for that first time.
You can already do that on most android devices. The Q just takes it to the big screen conveniently.
The function of being able to control the Google queue of device A from device B, C, D etc does not exist. Or at least I'm not aware of an app that does that.
I believe that I've tracked down the apk that does it on the nexus but I need to deodex the apps and can't seem to find a tool that works. Anyone out there deodex this rom yet?

Would love to have this functionality in an APK for me Google TV. Don't see why it wouldn't work, well other then no bluetooth on the Revue....
Still very interested in this thread regardless of GTV. I will be following your progress. Thanks!
.
I'm looking for this as well.
I have 3 spare HTC EVO's, and they all have HDMI out. I would like to be able to just plug them into the TV and use my other phones to control them / play music / etc. Maybe even throw XBMC on them with the ability to control from another phone..
They're slower, and less memory..but it may be doable.
Did anyone dig into this? I'd like this for the latest port of Android for a Raspberry Pi and willing to do some of the (noob)stuff myself.
That would be awesome to use any HDMI equipped phone along with the Nexus Q functionalities. I'm really interested.
I guess the problem with the missing API is that the Nexus Q runs android JB and he tried with a cm9.

Not true, Q runs ICS...
Let me know...
what I can do to help. If you give me a run down on what you would like me to try as far as pulling files from the q or my connected devices just shoot me a PM and i'll give it a shot. I too would love to add this functionality to my spare devices laying around.
I've been interested in this since day one as well. IT is what has me almost ready to fork out the money on more then one occasion. I have a party coming up and it would be fun to have my N7 as the Jukebox.
The Class issue, I'm not sure about. Here is some info that might get it started.: http://www.itcsolutions.eu/2011/08/...te-a-new-activity-class-with-manifest-editor/

It looks like it is something created with the app. Since you cut/pasted the apk into system it may not have been installed. But I'm thinking that it is something else. Some where in the android system lib's it is probably installed. Since this was a device dedicated to this purpose, they were able to install it into the system and the app calls it. I'm slowly learning to write apps (very slowly) so I am not sure beyond this, or even about this for that matter.
I do have a question. It looks like you pulled some system apps and put them in your galaxy tablet. I think a better test would be to basically replace all the /system contents of say a N7 (galaxy tab may work) with those from the Q. Then once it works, cut down the files until it stops. Then with a list of what is needed to make it work we could get down to the nitty gritty.
My guess is some more knowledgeable devs, like those who got Google Now working, would have a better idea.
I'd love to see a third party app do the jukebox function, I think a issue is license certificate (DRM) for the multiple users. I don't understand how the user is associated/authenticated for the music. One Question is if a user Ques up music then leaves does it cause that music to not be able to be played or will it still play once it's been que'd? My guess is the app just organizes the music/user who is next then when it's their turn it streams from their device in real time... but I'm really not sure about this.

Ok so here is some more detailed info for those of you still following the project.
HubBroker.apk is the app that is for all intents and purposes the "launcher" for the nexus Q. It will install on the Galaxy Tab and Nexus 7. It takes over your "home" and replaces it with a picture of the Nexus Q and a welcome sign. This app looks to be only the launcher as it doesn't do anything if you tap on it. Also having the app running doesn't allow the Nexus Q app (from your phone) to find the device.
So I assume that that the Q is controlled via bluetooth to get it setup and running. Including configuring the Wifi, network settings, etc. Oddly enough the app does send a request to android system to turn on the bluetooth and changes the bluetooth device name to Nexus Q.... The ... part is a odd string of characters that I assume is used in case you happen to have multiple Nexus Q's.
Now as just having the app doesn't seem to work (Phone finding the Q). I've replaced all the bluetooth libs with the ones from the Q. Still nothing. I've migrated all the other APK files and then I get FCs all over, and still no connection. I haven't tried replacing the whole system yet, but I assume the hardware differences would be to great. The only other piece of the puzzle I have yet to attempt it merging the kernels or at least the init parts of the kernel relating to bluetooth.
If you have any questions though let me know. I've been up and down this thing.
Why don't we just flash the img on an old phone and see if that works?

For that to work we'd need to get a device with similar hardware (CPU, Chipset, etc.) Not only that but it would need to have the same MTD setup unless I'm mistaken.
Actually I'm going to give that a try with the nexus 7. I'll let you know what happens, won't be till tonight though.

Galaxy nexus has very similar hardware. Someone should try porting it.

If someone still interested in the project, i'm very interested in it, i have a galaxy nexus (almost same hardware) so we can give it a try, im also a android developer, so if it need to build some apk for it to work, i could give a shot.
Anyway, if there is someone interested just post here and we do all we can to make that work.
edit: Only one problem, as I'm out of USA, i need the q apk to test if it will connect or not. I cant download from play store.
I'm sure there will be so many people interested in it. I just think that not to many of them enter this category on forum
I also need the nexus q image so I can flash it. I tried searching it but didnt find

Issues with Cloning Android to Identical Devices

Hey guys,
I have an issue I'm facing at the moment. I have purchased 3 Samsung Galaxy Nexus devices for my family, and one for myself. I wanted to setup all our devices for them and pre-install essential apps for them, and lay it out in a way which makes each device identical so that my family (which is new to Android) can all get the same easy experience from their devices, rather than everyone getting a different LG/Samsung/HTC device and having to deal with differences in skins every time someone phones me with a question about their device.
Here is what I have done:
1. Unlocked bootloader, root, installed CM10.1.2 + gapps onto my own personal device. Clean install, wiped everything.
2. Setup android with a temporary Gmail account, installed about 20 apps, setup the homescreen, changed a few settings for simplicity, change wallpapers, etc.
3. Once I was satisfied, I removed the google account, rebooted to recovery (CWM 6.0.3.2) and made a Nandroid backup which was later copied to my home server.
4. Unlocked Bootloader, rooted and installed CM10.1.2 + gapps on all the other devices, booted the device then transferred the Nandroid backup from my home server to each of these other three devices. Restore the backup, reboot, all seems fine so I setup new individual google accounts, and away I went. Everything works fine, at least so it seems.
Now the issue is that I'm having came a day or two after I got everything setup on each device. At the moment I'm having serious issues with the Google Play Store and Push Notifications. Almost all devices intermittently have issues with this. The play store issue I'm getting is [RPC:S-5:AEC-0], and prevents me from downloading or updating apps. Push notifications is not working either. For example, Google hangouts notifications don't notify me of messages on devices intermittently unless I manually check the app. Same goes with facebook and snapchat notifications. Very annoying. Tried all sorts of fixes such as removing the Google account, rebooting and adding it again, but no luck.
It seems like there is some sort of conflict with each device, but I don't understand why. I changed the Android ID on each device hoping that would help, but still no luck. If anyone could offer an explanation why this issue is occurring I would love to hear it!
Cheers.
Edit: Tried making a titanium backup of one device and moved it to a rooted Galaxy S2 running CM10.1 nightlies, and no such issue. Also, updated one nexus device to the latest nightly, still no fix. Hopefully this information will help someone be able to point out the problem somewhere.
Okay, so I've been playing with a couple of these devices today, and by removing a google account, rebooting the device and then adding the google account again, it makes the play store work on that device, but breaks functionality on the other devices. Would someone with a low-level understanding of Android care to explain why this is?
I'm going to try doing a factory reset on one of these Nexus devices and restore a Titanium Backup and see if that helps, unless anyone has any suggestions?
The different accounts are linked to the play store separately, you are best off to just downloaded each app and set up each phone with its own gmail account. I know it sounds time consuming but it would take less time than you've been spending already.
As you learn more about android there are lots of ways of doing almost exactly what you want here, but learning right now will take less time and effort than downloading 20 apps to three different phones

Thanks for the advice, but at the same time I'm using my family as guinea pigs to test whether it's possible to clone devices like this, as I'm in charge of the IT department at our organisation and I suggested it may be possible to deploy a large number of identical rooted android devices through the organisation (probably around 30-40 devices to start with). At this stage though, there seems to be some issues with doing this. Would you be able to point me in the direction of how I could clone Android to several devices, or at least deploy an identical setup to several devices? Perhaps I'll need to customize my own ROM based on Cyanogenmod? Chances are I'll be having to support different hardware as well. This may include the Galaxy Nexus, Nexus 4, Xperia Z and the LG Optimus 4X HD.
Well the absolute best way, in my opinion, would be to create your own ROM.
And by this I don't mean you need to learn how to port or build from source (at least not at first) just some simple zipkanging will do for something like this
Take the ROM.zip, open it, take out apps and such you don't want, add it the ones you do, rezip and sign
Now flash this to each phone and they will all have the same ROM and can just add their Google account.
Now if you want to have certain settings or the system ui look different than this you will need to learn how to decompile some apks and edit xml files, but start slow, do what is easy and what you can't figure out let me know and I'll try to help

Thought this might be the case.
Is it relatively simple to copy the changes I make to one ROM (eg for a Galaxy Nexus) for another ROM (eg. for a Nexus 4)? Is there some sort of Android virtual machine I can test or build this in?
Not simple at all, I was referring to multiple phones of the same type. Its easy to create identical ROMs to be flashed between 30 n4s or 30 genexs, but to create the same identical ROM to work in both types of phones would require source builds matched to each device tree
Which if you know little about android, java, c++ etc, then you have a real long journey ahead of you.
If you want to have an identical ROM (based off one already in existence) be flashed to 30 identical phones this is relatively easy depending on what all you want
Like I said, start small, learn what's easily obtained, then try for something bigger

The idea was to use CM10.1 as a base and simply add in some apps + app data and change some settings. Setting up the homescreen in a certain way would be part of that. The Galaxy Nexus, Nexus 4, Xperia Z, and LG Optimus 4X HD all support CM10.1 stable.
If I setup a device the way I want it, would it be possible to extract some of these custom configurations from the live device to a flashable ROM?
Just because there is the same ROM for each phone doesn't mean they are exact, but in your case probably good enough. But the change you would make would be to each individual ROM (on computer not on phone) and then flashed these new versions of your ROM to each phone.
You can not make changes to your phone when running the os and extract these changes and flash them to another phone easily, near impossible to do it to a different phone make
Like I have been saying, take a ROM, open it up on PC, change what you need, flash to phone. The simpler the changes the easier it is to do. This will have to be done on a case by case basis if you are doing it to multiple types of phones
Now if you give me a list of what you want to change exactly there may be a few things you can do on your phone but in reality this is the harder way, doing all the work on PC is the easier way
Sent from my Nexus 4 using xda premium
Yes, I understand that. I think what I'll have to do is record the changes I make to one ROM in a changelog of some sort, and then simply recreate these changes manually to other ROMs. Through the PC of course.

Well for example, here are the outdated and rough changes I need to make to the settings (this is just a note of the changes in the settingsof the ROM to make it run way I wanted on the device). Attached it as a PDF as I couldn't copy the formatting.
Most of that should be doable by decompiling systemui.apk and settings.apk, somewhat time consuming and depending on your experience a steep learning curve, but should be able to do it

[ROM][Development] Started work on G530W CM 12.1 Custom ROM

EDIT: Please direct any development questions, queries, etc. to the new thread in the Development Forum, concerning all development-y things.
http://forum.xda-developers.com/grand-prime/development/unofficial-cyanogenmod-12-1-g530w-t3424761
============================================================
I've recently started working on a custom ROM for the Samsung Grand Prime G530W [gprimeltevl/gprimeltecan], and so far I have built a somewhat working ROM (without any radio/wireless capability or audio for now).
If there is interest in this project (which I think there is; the lack of any kind of love shown for the G530W is annoying), I'll continue hacking away at it until I (hopefully) have a working ROM.
I'm new to Android ROM building in general, and there have been several bumps along the way, so any help would be appreciated.
Thanks.
I will be uploading images daily to my Drive storage, in folders named by date (if the date today is not there, then the image had not been built or uploaded yet), and will be compressing the system.tar images with either gzip or xz to reduce the image size.
I will also be updating this area with issues and fixes as necessary.
What I have managed to get working so far (23/07/2016)
Limited mobile connectivity [ sending/receiving texts ].
- Calls can be received or made but there is no audio (speaker or microphone).
- Mobile data is not working.
- Currently the system does not show the mobile connection as active, but texts can still be sent and received.
Bluetooth is working
Audio is working (microphone, speaker)
Multimedia playback working
GPS is working
Wifi is working
Screen brightness controls working
Sensors are working (magnetic, rotation/gyro,proximity)
App installation is now working
Camera is kinda working - only back camera works, and the image is distorted.
Issues
Radio [ modem ] is not working properly
NFC is not working
MTP is not working
Cameras are not working
Here is a link to the system.tar, boot.tar and recovery.tar flashable by ODIN or fastboot (when unpacked).

Great effort

Good work so far!
I recently purchased a g530w and I would love to boot the stock ROM.
However, I am still busy researching and reading up on this device before I attempt to flash anything. Actually, I did create an update zip file to remove Skype and tried applying it while not rooted but it failed because it was not properly signed.
Anyway, I will watch your progress with keen interest!

Sounds interesting. Did you try rooting your phone and using Link2SSD to remove the app(s)? It works pretty well, and you don't have to go through the whole effort of packing and unpacking the ROM.

Here's my plan for my new phone:
Reading and research (in progress)
Setting up Odin on a virtual machine (I am a Linux user) and testing a restore of the stock ROM. Do you have a good link to such a ROM? I briefly looked at http://www.sammobile.com/firmwares/ and this site looks a little sketchy to me.
Root the device. I believe the method described in this G530T thread has worked for our G530W.
Debloat the crapware. Surprisingly, there is not all that much on the device - mostly some Micro$oft crap, Skype, and an old, old version of Chrome which I cannot uninstall. As root, I'll just go in and delete the unwanted stuff from /system/app using a terminal emulator.
Once it get this far, I can probably live with stock Lollipop. Question, if you are learning how to port a ROM, have you considered starting with Marshmallow? I'm keen to move up.
Build the ROM myself and then attempt to build it with my Linaro toolchain which I built from scratch myself.
Questions, with what you know so far, will the G530H ROM in this thread work on our phone? Is this what you started from? What differences between the 2 devices what preclude it from working on ours - different hardware? software - i.e. different bootloader?, etc?

Hey Zippy,
That sounds like a good idea.
That website does seem kinda sketchy, and their downloads take millenia, but it's the only option available and their images actually work (just make sure to get the correct one).
Setting up a virtual machine is a good idea, because heimdall doesn't work with this device and I'm not keen on bricking my device trying to force it.
Rebooting between builds to test firmwares because of a lack of a good recovery was becoming a pain. (CyanogenMod Recovery is still missing critical features but it's better than stock).
You can use CF-Auto-Root to root the device (so simple) at:
https://download.chainfire.eu/774/C...uto-Root-gprimeltecan-gprimeltevl-smg530w.zip
Yup, debloating is good, i wanted to do so at first but I wanted to be done away with KNOX and have an su binary which worked flawlessly for good so I decided to start from scratch.
I've considered starting from M, but that will be a task for later. It is troublesome to start from a fimware above what your device is at when you're porting, because the vendor libraries and binaries you copy might not work in the newer version of Android because of linking errors.
You can copy the binaries fine but obscure errors due to missing references will pop up in the logs which will stop the modules from loading or binaries from running.
I'm having these issues with a build ID that is just a few apart from the one used on the stock ROM - LMY49J on the cm build versus LMY47X on the stock).
My Git repos are above - you can get yourself a cm12.1 source tree, pull my device_ and vendor_ trees, pull proprietary files using the scripts in the vendor tree, build from source and then flash the resultant images to your device.
The G530H ROM might, in theory flash without issue and actually boot, but whether it will be usable is another thing.
The thing that differs between the devices, as far as I'm aware, is mostly the baseband, some other device hardware (e.g the G530W has 1.5GB RAM instead of 1GB as most G530 devices), and the device bootloader. As such, the kernels and modules used might differ slightly in terms of modules compiled in, even though they're built from the same kernel source.
And yes, indeed, I started from a G530 device and vendor tree, though whether it was that one, or perhaps one for the G530FZ, I don't remember (though I think it's the G530FZ, it's the device closest to the G530W).
Finally something for this variant, I've been waiting for ages. Huge thumbs up dude, from a thankful Canadian. I don't use this phone as my daily driver so I'll be flashing this without delay. Mind if I trouble you for the order of operations? I've never used Odin to flash a custom ROM before.
Some more questions ...
Hi again @vince2678, I have more questions:
Do you have a local_manifest.xml that drives your build? ... I have a single-purpose Fedora24 virtual machine which I use to build android ROMs.
Does your build actually produce a CM12.1 zip installation package? ... And do you simply harvest the system.img, etc afterwards to put into a flashable this tar file?
What is the command line that do you use to create the flashable tar files? ... I'm just curious.
What version of the firmware does your device have? ... Mine has G530WVLU1AOFB. Apparently, this is the Tanzanian version! WTF? I purchased my phone from a Costco in Oakville, Ontario, Canada. It was purported to be unlocked for all Canadian carriers. My carrier is Virgin Mobile (owned by Bell) and it works fine. But, my understanding is that device actually locks to your SIM card upon first use so you can't use it for other SIM cards, but I haven't proven this yet. BTW, I got over half of the stock ROM DL'ed from SamMobile before it stopped due to a "network error". Yeah right! I'll try again later.
Have you (or are you) cherry-picking patches from the G530H CM12.1 ROM? ... android_device_samsung_fortuna3g I suggest DL'ing their key files and comparing them to yours. They appear to be in the final exhilarating phase of perfecting their ROM.
So you have totally removed the KNOX software without in deleterious consequences? ... I thought that I read in an XDA thread where somebody did this and then had issues such as connecting to WIFI, etc. It appeared that there may be a dependency in the BIOS.
Did you trip the KNOX e-fuse hence void the warranty? ... Not that I care about the warranty, I only worry about bricking the device.
Unlike @Pbotelho, this is my daily driver so I will be proceeding slowly and cautiously and look forward to his experience flashing it.

Hi Pbotelho, thanks man. You will have to enable Developer Mode on your phone and unlock the bootloader from the settings. I don't remember what exactly in the settings that option is, but it should be in the Debugging area for sure.
Once done, reboot into Download Mode [Press Power+Volume Down+Home].
Once you've done that, grab the boot.tar, system.tar.xz and recovery.tar from the links above. Extract the system.tar.xz with 7zip or `xz -d system.tar.xz` if under Linux to get a system.tar file, and flash the recovery, boot, and system, one after the other, in whatever order, by booting into download mode as soon as it is done flashing a file.
You will need to wipe your cache and data partitions, which can be done by rebooting into recovery [Power+Volume Up+Home].
The button options are built into the hardware so they can be used at any point after the phone is on.
When all that is done, you can report any problems here [or on the github page] and post logcats and I'll look at them if there's any issue I've missed.

Hi Zippy,
I do not have a local_manifest, if you want you can just manually pull the device and vendor trees into your build area, or you can make one yourself if you wish.
I will probably make one though, because the build has dependencies on some qcom sources.
I just use 'make -j8' to build everything, though you can use 'make otapackage' to build a flashable zip [You'll need the CMR recovery from here though, the images can't be flashed by stock recovery]
For creating flashable tar files, you can just use `tar`. You don't need to make .md5 verifiable archives, those are just to ensure a download wasn't corrupted [I provide md5sums for checking].
The system.img in the output directory will have to be renamed to 'system.img.ext4' and then archived, as so:
Code:
cd out/target/product/gprimeltecan
ln system.img system.img.ext4
tar cf system.tar system.img.ext4
tar cf boot.tar boot.img
tar cf recovery.tar recovery.img
Then you can move the files wherever and flash them with Odin.
Yes the gprimeltevl/gprimeltecan baseband is indeed G530WVLU1AOFB, though this should work with all G530WXXXXXXXs (not sure how many different ones are out there].
I'm not sure about the SIM locking thing, I cannot confirm this, someone might have to try to check.
I did consider sourcing from that repository, though ultimately i ended up using another one [I don't remember the name]. I might take a look at their source to see what I can do about mine though.
I did trip KNOX, though that was back when I was still trying to root my phone with CF-Root, so I'm not sure if flashing this will trip KNOX. And yes, KNOX is completely gone from this device, with no problems from the phone.

I got impatient with it so I took a gamble and inferred with some background knowledge. Got it up and running several hours ago. Performance wise, it seems dead on perfect. There's no lag, no force closing of apps. Everything runs as snappy as it should. Its fast as f***. Now I even installed xposed framework and added in a few modules, one of those being the Android N-ify project, and it works really well with it, so kudos on this area. I'll be sure to uninstall xposed when it comes to error reporting and logcats.
The only issues I'm seeing besides the ones you've already outlined are graphical in nature. I'm not home at the moment but I'll upload some logcats when I get the chance.
1) What I'm seeing is a blackout out lock screen. I have a theme installed and used it to apply a custom lock wallpaper to test this out. The wallpaper only shows once you've accessed the Pattern input by swiping up. Haven't tried it with a pin. If you're only using swipe, it'll stay black until unlocked.
2) When unlocked and swiping down to access the notifications panel and quick settings, the same blackout effect is present. This is present only while you're looking at your notifications or tiles, and returns to normal when swiped back up.
3) The first half of this part is only noticed when using the material glass theme. When swiping down to access the notification panel without notifications, the "no notifications" text will be present as it should be, however, when swiped down again to access the quicksettings tiles, the "no notifications" text isn't cleared away. It sits behind the brightness slider. This isn't noticeable on the stock theme because its opaque, while material glass features transparency as their main selling card. If using the battery saver, the text from this persistent notification will appear instead.
Edit: Upon further analysis, it seems that the notification content is linked to the bottom of the header instead of the bottom of the quicksettings tiles, and that's why it works this way. When expanding or shrinking the header, the notification also moves directly with it.
Second half: whether on the stock theme or not, the "no notifications" text will continue to stick and be viewable on the lockscreen, retaining its position that is viewed in the notification panel. It sits directly above the clock. The persistent battery saver notification works the same way. I'm no expert, but I believe that since the notification panel and lockscreen both go to black, that this might be linked in some way.
4) Sometimes when using the stock theme and toggling options in the quick settings tiles, it'll glitch out and turn into what I can only describe as a zombie menu. The pixels of the status bar are replaced by that proportionate area of the quick settings menu, and when swiping down to use the menu, access is disabled (it can't be touched) and it closes itself when attempted. Only way I've been able to fix it was to toggle the theme to material glass and all was restored, still subject to the above three points.
Edit: 5) when using kernel adiutor to try to adjust the CPU frequencies, the only option that comes up for both minimum and maximum is 0MHz. The button seems to work as well, bringing the clock max speed down to 0 for a split second before it reverts to a a maximum of 200MHz. Adjusting the governor after the fact won't restore the maximum, seems only a reboot will get it done. I'm slightly amazed to be honest as before on Touchwiz, it was impossible to get it to hold onto a lower maximum. It would jump all over the place as it pleased.
Edit: 6) The recents hardware button is disabled. Touching it, holding it, nor double tapping brings up a function. It also isn't present in settings when trying to map the button functions. Its the only one that's missing. Power, home, back, and volume are all there.
That's all I got for the moment, I tried to be as descriptive as possible as I won't be able to get the logcats up for awhile. Let me know if you have any questions about what I've said here.
And also, are you taking feature requests?

I got impatient with it so I took a gamble and inferred with some background knowledge. Got it up and running several hours ago. Performance wise, it seems dead on perfect. There's no lag, no force closing of apps. Everything runs as snappy as it should. Its fast as f***. Now I even installed xposed framework and added in a few modules, one of those being the Android N-ify project, and it works really well with it, so kudos on this area. I'll be sure to uninstall xposed when it comes to error reporting and logcats.

Hi Pbotelho,
I'll try to answer everything as completely as I can.
The blackout lock screen thing seems to be an issue with Trebuchet. I found that using a different lock screen app solves this issue.
As for the blackout on the notification area, I'm not sure what exactly is causing this, though I think this may be a problem with the cm-12.1 source and not necessarily the device port itself.

This seems to be an issue with Trebuchet again, and using a different lock application fixes this.

I'm aware of this one, for now you can fix this by disabling Brightness Control in the settings ( Settings->Status Bar->Brightness Control).
This again might be an issue with the cm-12.1 source, though it'll need some checking to confirm.

I'm using Kernel Adiutor and frequency setting is fine. Did you try using a tunable governor like interactive? That may be the issue.

I'm aware of this, you can blame this on my bad arithmetic skills . I had set the wrong bit field mask for the button settings in the device frameworks.
I'll be pushing a fix addressing this shortly.
And also, are you taking feature requests?

That depends on what the features are, if they're reasonable and within my capabilities, then yeah .
PS: I would appreciate any help I can get, and if you have any coding skills and time to compile builds, you can help me polish up the device port.
Thanks!

1) Aww man I love using Trebuchet, I like to keep my install as small as possible so I'm not one for installing additional apps. I'm a resource junkie though, so its just a matter of personal preference.
2) Again, I'm not an expert, but I suspect it might be the device port. Previously, I've had an unofficial version of CM12.1 installed on a Galaxy Tab 3 as well as a CM12.1 based Pac-rom installed on a Galaxy S4. I'm not sure if this is something those developers corrected on their own or not when building their ROMs, so it could be the source. That's the best of my knowledge on the topic.
3) Will do for the brightness slider, but again, it isn't something I experienced on the other devices with CM12.1 and the sister project.
4) Yeah I played around with the governors and tried all of them. They all list 0MHz as the only option. Maybe its a CPU hotplug issue? I didn't try playing around with those so I'll have to get back to you on that one.
5) Look forward to the update I have a question regarding it though. I'm really familiar with updating custom ROMs through recovery using the zip file format, but this is the first time I'm using Odin to do the job. Will flashing an update with Odin this way cause a factory reset? Or will it update as expected?
6) A couple more graphical hiccups I remembered. The blackout also happens when going to About Phone>Status. In About Phone, the device field says unknown (doesn't bother me, I just don't know if its significant or not), the illumination for the hardware buttons isn't working (I usually keep them off to save battery anyways, but someone out there probably uses it). And finally, when switching recents by holding the home button, only the title bars of the individual apps are viewable. The content of the windows themselves is completely transparent so it looks like a series of floating title bars.
(Apologies if some of these features are already included, I didn't get the opportunity to check, I just think they're awesome)
Feature requests:
1) When phone is off and charging, percentage is displayed inside battery symbol.
2) CPU and GPU undervolting built into the kernel. These custom ROMs are much better than the stock ROM in terms of functionality, but the battery life on the stock Samsung experience is no joke.
3) If possible, more steps for CPU frequency adjustments, every 100MHz or so. I remember the stock ROM had limited options. My S4 is the example I'm going to use here, it has a step for every 108MHz.
4) USB fast charging, aka setting USB to "charge only".
5) Wakelock Blocker. Its built into the latest Resurrection Remix for the S4, not sure if that could be of viable use to you. It'll certainly help out with battery improvements.
6) Boot Manager. Decide which apps get to start at boot. Its built into Marshmallow and an xposed module also exists for this purpose, so really low priority on this one, for me at least.
7) This one is a doozy. Absolutely the one I care most about, but most likely asking for too much. USB tethering. Already exists, I know, but not the way I hope it to. I have an old WRT54G router with DD-WRT installed. My goal is basically this: Phone's network connection>USB Tether>Micro-USB-LAN adapter>WAN port of router. In this sense, the phone would be acting as the modem in a regular home network. I know its possible to do this if the router has a USB port, but mine doesn't, and I also know its possible if you have an intermediate device that bridges the connections for you. Like a laptop, PC, or raspberry pi. Cost efficiency as a student is what I'm working towards though, so this one is a wishlist request.
Ps. The only coding skills I have are from high school's Visual Basic and HTML, truly beginner stuff, and that was about 10 years ago. I'm running Ubuntu on a core i5-2500k with 16GB of RAM and about a terabyte of space though, so compiling is definitely a possibility with some instructions.

Nope, this should be pretty much the same as flashing a zip from recovery. If you modified the system partition though (like by flashing GApps for example) your changes will be lost.

I fixed this in the device tree, once I've built a new image this should be corrected.

I don't quite understand what you mean by this, how does it differ from the normal USB tethering?

If you can't code, that's fine, you could set up a build environment on your computer for creating images from the source.

Sounds awesome, I'll flash it as soon as possible and continue testing it for you.
I uploaded a logcat to the other thread in development. The performance governor is set up as the default for me so I'm set up with that situation from the get go.
It technically isn't different from regular USB tethering, but it seems that no one has done it successfully before. There are adapters that you can use to provide a wired Ethernet connection to an android device over micro USB, but no one has been able to do it the other way around. Google results don't turn up any answers.
And I'm willing to learn how to code, but I fear that I may slow you down with this project as I get past the learning curve. That being said, I can definitely set up a build environment and compile it from source for you. That'll be a learning experience on its own. Just point me towards a noob guide and I'll get it done.

The USB tethering thing sounds interesting, though I would need to have one of the adapters to test that, and time at hand as well.
As for the build environment, the best source of information is the CM wiki. You can look at these links below on how to get started:

The guides above are just outlines to detail the general build process - you will need to do things slightly differently from the steps above to get the proper source and device trees.
The attached local_manifest can be used with repo when obtaining the cm-12.1 source.
Remember you'll be getting the cm-12.1 source - not anything else.

So if I add in your device tree and provide a toolchain, I should be good to go? (I think so.)

I've test Kernel Adiutor and I too got the O MHz only window for both as the only option. Though Now I wonder if it is because I used the latest beta Kernel Adiutor, I'll further check with the normal stable version. Pretty sure it'll fix it if it worked normally for Vinc. --- Update; As strange as it might look while re opening kernel adi to take a screenshot, the list of normal MHz values is there and working properly.. Strange.. Magic? Huh technology, you're so unpredictable.

Hi Zippy,
The kernel source was included there as well (it's just a dummy source so that the build can get the necessary source files for libraries which need them). The build still uses the default prebuilt kernel though.

As an experiment, why don't you try downloading the G530H ROM, unzip, take the boot.img, and flash it over top of your stock kernel? See if it boots and how it performs.
Meanwhile, I plan to hack at putting together complete manifest, possibly with the G530H kernel and my Linaro 4.9 toolchain and see if I can build a complete ROM.
Have you extracted the firmware?
However, I don't want to flash anything until I see your ROM's modem working because it is my daily driver. But I'm keen though!!
I've managed to download the stock ROM from SamMobile but I'm now thinking of going straight to your ROM once it is a bit more complete and stable.
