Okay! By the way, pushing
/system/lib/libHWComposerGC.socauses the tablet to go into a bootloop and turn the CM logo to yellow. What could be the cause of this?
I've actually had success pushingYou can push /system/lib/hw/hwcomposer.mrvl.so and libHWComposerGC.so from the stock ROM, but it will bootloop with CM logo loading with frame-skip like effect.
I don't find in logcat an error about it, it just reload the HWC after some audio and mediaserver problem. Might be due that.
However, I suspect that the CyanogenMod HwComposer needs to be patched before compiling in order for this to work.
With hwcomposer libraries from T210 4.4 stock ROM it got some errors and don't load them. Also tried different combinations of VIVANTE, MARVEL galcore, etc. graphic libs from different devices (T210, T230, some others from internet) and still didn't manage to get the HwComposer to work and hardware acceleration.
This is what it is. I didn't have the Linux environment I've used to compile the CyanogenMod and all the settings and patches I've made to get it to this point, so I can't compile it again.
Here you can see the logcat:
Hmm, actually I see there's an error:
E/v_hwc ( 125): open /dev/graphics/fb2 failed
But don't know if is serious as:
I/v_hwc ( 125): Detected display /dev/graphics/fb0
hwcomposer.mrvl.so, but no success with the other file. It seems like we have to patch that?

i really think pmOS is a good choice, but i dont think it is gonna work well because of cpu limitations, but i can try my best to help.If you want to give a hand at getting the pmOS booting on our tablet, check this:

To answer your questions:
1. Closed souce CPU, we are basically working blindfolded
I'm pretty sure those are for the T110 and T210 mixed (because only the SD8787 driver exists) and the 4.4 part is for the T210.Hello @Tsumetaay
Maybe you can use this? ruben15pdr found these when available on the Samsung site.
Samsung released files for 4.4 update:

Files I've still got from then:Here's TWRP 3.0 for T110 / T111:
L.E: You find it in the links bellow.
I've used @gr8nole TWRP for T210 to port it to T110 / T210, so thanks to his work.
Flash it with Odin, remember to uncheck Auto Reboot. After flash, first time boot in Android, and then try to boot in recovery using vol up + home + power.
It will take about 10 seconds to boot (black screen)
