Thanks a lot. I cannot run Ubuntu on virtual box. I forgot to copy the error that I keep getting. I'll send the screenshot tommorow. Anyway, I'll start working on the kernel

Update7: Development resumed. Thanks a lot to @jlazkano for decompiling the boot.img. Anyway Ubuntu still does not want to cooperate or my hardware is just not right. I'll send the error screenshots in virtual box tomorrow

Hello,

Wich version do you want?

14.04 will do......keep in mind that I only have 1FGB of ram and an Intel Core i2 formerly known as Core 2 Duo. But thanks a lot man. I'll pm my email so you can send it

I had same problem with Ubuntu like you. I figured out that hardware acceleration wasn't working but I haven't found a fix for that. I just used my older PC where everything worked correctly, but you've got a very nice CPU(popular, capable, powerful) when I have cheap AMD64 Athlon 4600 processor and Ubuntu doesn't like AMD so much but it liked my Intel Pentium T4200

Well OTG can be plausible, working on cyanogen. I don't have a proper distro of linux as of now.

My ROM making skills aren't that good yet, but when it comes to Linux, I know my stuff. So I'll gladly help you :)
Question: why are using Ubuntu? Have you tried Debian or if you want to be more on the bleeding edge try SolydXK.
Both are "rolling releases" (as opposed to a fixed release like Ubuntu or Mint) which means you only have to install once and forever update. Whereas with fixed releases every time another release comes out, you have to re-install.

As for trying a Linux distro, forget USB sticks or Unebootin. Use DriveDroid instead. It's brilliant, you just have to copy on device SDCard, the distro ISO that you wanna test or run (and you can have multiple distros at the same time) and DriveDroid takes care of making it bootable, and then just connect your phone/tablet to your computer with USB cable to boot the Linux distro of your choice.

Don't hesitate to ask if need any help/guidance

Okay. So I found out what's causing errors.
Mic: Driver problems
Slow UI: GPU problems
ART: Apps are not configured to run in ART
Camera: Drivers
Screen Problem: Either Driver, GPU, or Value problems
2 Step volume: Values not set properly
WiFi: Driver or vendor problems.

Some of these may be true some may not. And I'm gonna need a lot of help. Calling out to @gr8nole. Pls let me help you or can you help me. As this is your project after all.

I have absolutely zero interest in this project now. I put in way too many hours working on this device and it is way too frustrating trying to get this Marvel junk to work.

Good luck!!

GPU has upstream driver now (etnaviv). Wifi/bluetooth has upstream drivers.
Mic and camera do not (as far as I know) have upstream drivers. I've been working on getting kernel updated to linux 3.4.67 (for ease of porting). Right now I'm stuck at 3.4.11 (there are some sdcard changes there).

See https://gitlab.com/sm-t210r/android_kernel_samsung_lt02 and https://gitlab.com/sm-t210r/android_device_samsung_lt02wifi.

The first is the kernel source I'm working on and the second is my (personal) device tree, with a file giving driver information (first entry into the kernel, not where it is working for the specific silicon in the SM-T210R).

Can someone help me? I installed this and stupidly enabled ART, but it worked fine. After rebooting after rebooting to ART, the screen has been f**ked. It flickers between the colours normally and it like shakes. I'm on 4.1.2, the orginal firmware, kernel, recovery and stuff is all there. I don't know what happened, but if I take a screenshot and look at it on my PC it looks OK, and when I boot it up & go into download mode, the colours and screen are fine. I don't know if this is related; like the screen stopped working after I rebooted on ART. Thanks in advance. I'm gonna go post this on Q&A as well. To check screenshots check here: http://forum.xda-developers.com/galaxy-tab-3/help/screen-flickering-colours-changing-sm-t3343396/post65998297#post65998297

    THIS PROJECT HAS BEEN ABANDONED

    Please stop emailing me about this. I have no intention of resuming development on this or any other rom for this device.

    THIS ROM IS NOT READY FOR THE COMMON USER.

    This thread is dedicated to the further development of CM11 for the T210. Please do not post bug reports for the time being. I am aware that it has many, many issues. Please only post relevant DEVELOPMENT discussion.

    Please do not post requests to make it for another device. We "may" be able to if we ever get this to a decent status.

    CyanogenMod is a free, community built, aftermarket firmware distribution of Android 4.4 (KK), which is designed to increase performance and reliability over stock Android for your device.

    Code:
    #include 
    /*
     * Your warranty is now void.
     *
     * I am not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you getting fired because the alarm app failed. Please
     * do some research if you have any concerns about features included in this ROM
     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at me for messing up your device, I will laugh at you.
     *
     * Submitting bug reports on nightly builds is the leading 
     * cause of male impotence.
     */

    CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review.

    OK guys, I know it's been a while, but I have a little bit of good news.

    I did finally manage to get the hwcomposer working (with correct colors).

    Still haven't even looked at wifi again. Today was the first build I've compiled in a couple months, so don't get too excited. I don't have much time to spend on this at the moment, so please don't ask for an eta.

    Just wanted to let you guys know that I haven't given up.
    20
    pre-Alpha-3
    fixed auto-brightness
    removed calling/mms parts

    Not much progress on wifi or hwcomposer fixes.

    NOTE: Stop mentioning me and ketut in your other T211 threads. Constantly mentioning us does nothing except distract us from what we are doing.

    very veryy sloww devoloping uglyy

    Maybe you just need to stop with saying these kind of things you realy think this motivates or helps the developer NO WRONG!!!

    First of all your name is not realy original but you already knew that second you keep saying these kind of things and third but not least if you keep saying these kind of things DEVELOP BY YOURSELF!!!
