Hi, sorry to post of question here, but it seems it is the only place where it is possible to talk about development for the GT-73xx.
I would like to do some work on the kernel, I am looking at this : [not allowed to post a link to motley-git]
But is there a guide on how to compile this GT-7310 kernel, and how to safely flash it to the tablet ? Does Samsung publish the source code of the bootloader ?
My goal is to develop a simple graphical user interface for a particular application using OpenGL but still be able to access the hardware features like WIFI, Audio, USB and multi-touch. So the tablet would only run my application.
I do not really need to run the Android OS (especially any java components), but if there are some kind of hardware android APIs I can still use from my C/C++ app, that would be great.
any help will be much appreciated

Hi
XDAndroid is so cool! Of course a few unstabillities.
I have seen that there is an userland camera fix. Does anyone have a link to a thread about this?
I have TD2 Topaz
Actually, user-land support is there in latest builds. However, that doesn't mean that camera is working.
The simplified architecture of Android (or any *nix based system for that matter) is as follows:
Code:
User (You!)
-----------
User-land (Applications, Daemons...etc.)
-----------
Kernel (you could say drivers)
-----------
Hardware
Each level interacts with what's above it and below it directly. Meaning, for the camera to be usable, we still need to wait for the kernel side support which is still a work in progress.
I hope that makes sense.
Yes thank you
pro explanation for noob users! thanx
Hi,
I have just bought a new Xperia Pro and Here is My first Contribution.Hope you guys like it.
I have tested it personally on the Unoffical MIUI port for PRO.But it should work on other Kernels and Xperia Devices as well.
I am posting a few Screens for you guys and as you can see lxde is already pre-installed for you guys.

What is chroot?
A chroot image is like a Virtual Machine where you are running an O.S within an O.S.The point of this is that you have a whole Linux System running on a phone where you can ofcourse access all the utilities available in Linux.and as it runs inside of android you dont need to flash anything and can use both the chrooted O.S and Android together.
Things required:-
1)Terminal
2)Root
3)Sdcard with atleast 2GB of free space
4)A Brain

Hi! Have you tried this on stock kernel? I believe stock kernel doesn't have loop devices enabled and MIUI is a rebase of CM? Not sure though that's why I'm asking.

The Miui i used was on Stock Kernel.The Kernel Does Support Loop devices.Miui is a Rebase of CM but the loop functionality is related to Kernel.So,Yes it Works on Stock Kernel on Locked/Unlocked Bootloaders Both as we are not flashing anything.
Anyway Give Ubuntu a go.

Thanks! Just clarifying things out I haven't meddled with stock kernel that much that's why I am asking. Well the kernel sources sony provided has loop devices disabled by default glad that it's enabled on the official precompiled one.
Anyways! Try packing backtrack that should be alot useful than debian w/ lxde or a classic ubuntu image.
I got backtrack to run on Pro sometime ago when I was still using gingerbread.

Hi! seeing that you're a fanatic of these perhaps it would be useful if I give you these.
http://50.56.186.177/filez/
Those are packed and reduced sizes of debian & fedora arm images made to fit for chrooting on mobile devices. I made those for my previous device and is very stable already with 256mb RAM
the debian image is a squeeze version. Plus included is the fix for pulse audio. I'm not sure if it would work out of the box for android but with just a little bit knowledge with basic linux stuffs you could get it running perfectly

THANKS for the link...Meego wont chroot..tried it on the optimus a few months ago and failed..problem with zephyr..will give it a go later.fedora I had as well..but the thing is ...Does anyone except me even use these here????
I do but not that much. Like I said I just only tried backtrack and obviously I use it only when needed
Say do you think it would be possible to include a custom kernel on a chrooted image? It would be cool if we have backtrack here with monitor mode enabled. I think the wlan drivers/hardware of Xperia devices have the capability.
Or also try posting this thread to some other Xperia Sub forums. Arc/Pro users seem to be not very open to these kind of works. They just care on custom ROMs
In short they aren't geeky enough They aren't even that interested in dual booting.

In theory yes its possible.but changes will have to be made to the arm kernel to chroot.when u type uname in terminal the output inside the chroot is different than the android kernel.but I think native booting will be better than chrooting..not being interested is just odd....its so much fun having linux on the go

Actually I know I am going to say something Off-Topic
1) People on XDA are now the people who have got a smartphone just because they can afford one and wanna make their phone look "kewl" than the others with the same device
2) People do dumb things like cross flashing kernels.. They dont even read carefully what the OP says..
3) Running linux on a phone would be the best thing.. specially on an xperia pro where you get a harware keyboard..

Hi,
I am going to chance my arm and try and produce a modified kernel for my Z3C. The reason/incentive is because I want to add NFS filesystem support to my device for Kodi/XBMC. I've had a look at a guide that suggests all the necessary components are made available by Sony to do this.
1. Have I missed something and is there already something to provide NFS without me wasting my time?
2 Is this a stupid idea to start off on for someone with no dev experience?
3. Are there are any devs on here who would be open to offering limited support/advice if I get really stuck?
4. Assuming I am successful I will of course load the Kernel up on here for other people to use if they wish.
Cheers,
Ant
Have been busy porting the SM-T285 to OmniRom 5.1, would just like to post the progress so far:
I've managed to reach a point where I managed to get graphics working and bring up the Android Home screen, however I still need to fix wifi, bluetooth,cellular.
If anyone can point me to someone who has experience porting spreadtrum devices, esp the sc8830 please pm me.
Below is a semi working SM-T285 device tree that I am currently working on:

I got rild working, now trying to get wifi up.
Current OMNIRom status for the SM-T285.
1. Phone/LTE Services - OK
2. Graphics (hwcomposer/gralloc) - OK with bugs
3. Wifi - Still need to fix wpa_supplicant issues OK (10/20/2016)
4. Bluetooth - Broken, stock uses a custom bluedroid lib, will need to reverse engineer bluetooth commands
5. Audio - OK
6. Accelerometer - OK
7. GPS - Not Tested
8. USB Services (adb, tethering) - OK
9. Camera - Broken
Will post ROM once I sort these issues out.
Looking forward to this. :good:
I've just switch to porting OMNIRom 6.0 to the SM-T285, screenshots here:
SM-T285 running marshmallow
ril got broken when moving from 5.1.1 unfortunately, so working to get it back on. However there are now no more graphical bugs, the SM-T285 actually runs impressively on the Marshmallow
A release should be happening this week, I hope I beat samsung to Marshmallow with this device

Haven't tried, however I am led to believe that safetynet fails in general for all custom roms that is not based on stock like CyanogenMod or Omni.
Hello there, your work looks very good so far! Its good to see that someone finally takes care of the Tab A 7.0
Are u planning a T280 Release too?
Greetings

Quick question, I have very little or no experience about porting a rom. How do you do it and what applications and guide do you use to port a rom? I have a SM-T350 and I'm going to port Cyanogenmod 14. Thanks for the reply, in advance.

I don not personally have an all in one guide that I am following. There are various sites that provide bits and pieces of it, for CM, they have their own porting guide here: https://wiki.cyanogenmod.org/w/Doc:_porting_intro
Unfortunately, the guide above is only good for creating an initial setup. To be able to make the rom work on your device, you are probably going to need a bit more, sites like android open source provides a brief overview of how the bits and pieces work at a low level:
https://source.android.com/devices/index.html
I also had to deal with SELinux, and this is the part where there is a lot of lacking tutorials.
Next is mostly device specific. The best case scenario is if your device already has a CM port available (previous version) or if a device with similar hardware has it. If the SM-T350 already has a CM port available somewhere then your job is going to be a bit easier. If not it is going to extremely hard depending on what sort of hardware you are dealing with. There are some hardware manufactures that provide good support like Qualcomm and those that aren't so good at it Spreadtrum *cough*. In my own experience with the SM-T285 there aren't many devices with CM around that sport the same hardware, the best I got going was a Samsung Galaxy Core (core33g) CM port that I found in github after looking really hard. The real challenge is figuring out how things work and what "changes" the specific manufacture did to existing aosp. There are times where you are forced to use the stock (proprietary) libs and attempt to shim(patch functions) them to work.
I already have experience compiling CM from source since I also have a Nexus 5 which has pretty good support. I also have several years experience as an Android Developer as well as prior dev experiences related to Java/C/C++. You should also be familiar with the languages used in building android namely C/C++, Java as well various scripts as well as dealing with linux as there would be times when you need to make modifications to backport/forwardport functions used by proprietary libraries.

Thanks for the info by the way. Can you add me on XDA-Developers so I can ask you any questions for going through the process of making your own rom? SM-T350 doesn't have any Cyanogenmod but only an EVERVOLV rom that has many bugs. Also do you have a tip or a link for Java/C/C++? I have no experience.
Thanks if you respond back!
Hi,
I am trying to buy either one mention above for below purpose
best result,
I would like to remove android and Install a linux for ARM.
at least,
Remove almost all apps(bloatware google etc) and get root access and have some remote desktop app working.
Also does linux on dex work on any of these devices?
Which would you suggest for better XDA forum support? SM-T510NZSAXAR or SM-T510NZKWXAR
Thanks
