Last two builds before are exactly the same

yes i downloaded it can i flash the 13122013 build with twrp 2.6.3.0???
[Galaxy Tab 3 7.0 Android Development] Unjustified Dev:
Yes just follow that guide to switch the update binary latest build won't need this done. It uses set_permission instead of metadata

This one did flash, but it was black on boot. Could not get adb to recognize the device (even after trying to set the prop correctly).

Did get the last_kmsg from recovery.
[Galaxy Tab 3 7.0 Android Development] gr8nole:
I flashed the regular blackhawk kernel and was able to get a logcat.

I'm not sure exactly what the differences between the kernel configs are, so some of the issues in the logcat may be because of the different kernel.
[Galaxy Tab 3 7.0 Android Development] :
The kmsg looks like it always looked when we included stock EGL and GLES, I think. logcat also complains about EGL (starts around line 900 [450 when not counting empty lines]):

12-13 13:11:33.007 W/SurfaceFlinger( 1964): no suitable EGLConfig found, trying a simpler query

It then loads the android EGL driver and Vivante Open GL ES driver and complains about a missing "trace" file and missing lcd density:

12-13 13:11:33.007 E/cutils-trace( 1964): Error opening trace file: No such file or directory (2)

12-13 13:11:33.015 D/SurfaceFlinger( 1964): Screen acquired, type=0 flinger=0x4047c008

12-13 13:11:33.054 E/SurfaceFlinger( 1964): ro.sf.lcd_density must be defined as a build property

After that it shuts down:

12-13 13:11:33.070 F/libc ( 1964): Fatal signal 11 (SIGSEGV) at 0x0000004c (code=1), thread 1964 (surfaceflinger)

I already had the lcd density error, I could disable it by defining ro.sf.lcd_density but it did't boot anyway. This was when I used android EGL and GLES drivers though. I also had the trace-error I think. I thought it was unrelated because it isn't issued by surfaceflinger but maybe I was wrong...

The rest just looks like same ol' to me ;)

[MENTION=3034891]gr8nole[/MENTION] kmsg has no errors. Yes , exact same thing. I am going to build some things from source. As before this is my last build I am releasing. You guys can continue to work on jellybean. I will be spending time on fixing kitkat since I have my tab now.

[Galaxy Tab 3 7.0 Android Development] N00BY0815:
Could the black screen be due to missing permissions? Because if I remember correctly, that's what made the other build boot. Maybe you should check that. But other than that, the log looks really good.
[Galaxy Tab 3 7.0 Android Development] :
Really nice, could it be that it's because of lcd brightness it isn't set at all in your logcat? PowerManager sets it up in Stock ROM. Maybe disable power manager? I saw LCD brightness somewhere in stock config files, just don't know where...

Also, you have this:

W/SurfaceFlinger( 119): /sys/power/wait_for_fb_{wake|sleep} don't exist

could be a problem too?

I hope I'll find some time for testing...

[Galaxy Tab 3 7.0 Android Development] Unjustified Dev:
Um , Ok , this thread is not to ask on progress if you want that please P.M me. This thread is only for development related things. If you don't have input on developing I suggest posting in the general thread. I have made progress as I am trying to get back to the booting status I previously had. If I can get back to that state , I can fix the no gui problem. I am now facing an error I had solved when I got it booting with black screen. Now i can't recreate that status. I have been trying every other day to get back to that status.

http://pastebin.com/J18XvWTQ

Here's the logcat that booted. Now the gralloc isn't loading and that's now crashing the surface flinger on my other builds. I have gotten closer to fixing this.
[Galaxy Tab 3 7.0 Android Development] N00BY0815:
I still havend had the time to check the booting build, but might it really be a missing lib, like:

D/dalvikvm( 120): No JNI_OnLoad found in /system/lib/libchromium_net.so 0x0, skipping init

There are some more, which have to do with camera and sound, that seem to be missing. I also thought of the kernel already. Did you try the one from the booting build? Not that we try to debug the system here, but it's the kernel, that doesnt let it fully boot. Or is the dmesg clean?

Thanks again for still investing so much time in our toy ;)
[Galaxy Tab 3 7.0 Android Development] N00BY0815:
I am just about to check out, if you maybe missed libs. But can you maybe check your build.prop? Your version information is somewhat off... In the upper part it shows: 4.4.2 and in the lower part it says 4.1.2.

Maybe that "confuses" the device...

What i noticed till now going through the libs, is that /system/lib/power.goldfish.so is missing. Dunno if it is really necessary or not ;)

-EDIT-

Replaced all libs, but got stuck with no sign of life at all... Gonna try with the boot.img if gr8nole now. If it is not that neither, it has to be either one of the other folders (especially etc, bin or xbin), the build.prop, or the updater-script. Gonna replace it one by one, to see, when it starts booting.
[Galaxy Tab 3 7.0 Android Development] Unjustified Dev:
Actually gr8noles source is missing a lot no offense. My issue is the kernel now. I've reverted all changes back to normal and the modules are kernel specific they have to be built with the kernel as far as I seen or they crash they even have the kernel name in them. You can use the modinfo command to read a module file. It explains what it is for. I have finally learned how to compile them it's not hard thanks to [MENTION=4021423]ketut.kumajaya[/MENTION] . I haven't yet pushed changes to anything except kernel. I am trying to get somewhere before pushing

The error failed to open device is holding back a successful boot like previously.
