Based on @sw6lee 's build.prop information, Samsung Galaxy Tab 4 7.0 powered by Marvell PXA1088 SoC.
Code: 
ro.product.model=SM-T230NU
ro.product.brand=samsung
ro.product.name=degaswifiue
ro.product.device=degaswifiue
ro.product.board=PXA1088
ro.product.cpu.abi=armeabi-v7a
ro.bootloader=T230NUUEU0ANE2
ro.product.cpu.abi2=armeabi
ro.product.manufacturer=samsung
ro.product.locale.language=en
ro.product.locale.region=GB
ro.wifi.channels=
ro.board.platform=mrvl
Also confirmed by Vivante: http://vivantecorp.wordpress.com/2014/05/02/vivante-powers-samsung-galaxy-tab-4/ . Vivante is the GPU maker for PXA1088 SoC, GC1000.
More information about PXA1088: http://www.marvell.com/communication-processors/pxa1088/features.jsp

I experienced working for PXA988 device Samsung Galaxy Tab 3 7.0 in kernel level, though I don't own this device. Based on Marvell, PXA1088 platform compatible to PXA988, both powered by Vivante GC1000 GPU. Some information for you:
  • Tab 3 7.0 ramdisk size limited to 1MB from the bootloader, too small for custom recovery
  • No USB host support, hardware limitation
  • No AOSP reference out there, it's hard to build a custom ROM
I managed to fix ramdisk size limitation https://github.com/kumajaya/android...mmit/2f156084ddcdea962ce23d68ad6a7b191dbc0075 and immediately custom recovery available for Tab 3 7. With touchscreen fix https://github.com/kumajaya/android...mmit/caa7019bcca4ce714d3c1288ac5471334acb0d98, touch base recovery also available. It's hard for the other two problems and I have no access to Tab 3 7.0 device. Custom kernel also available for Tab 3 7.0, of course from me ;) Somehow only xz compressed boot/recovery image manage to boot Tab 3 7.0 :laugh:

Tab 4 7 owner, it's a good idea to upload your device boot.img and recovery.img here. I'll investigate it for you :good: Give me your device "cat /proc/cmdline" output.

Wiki can be edited by anyone. Just run the cpuz app on the 7.0 and it will confirm marvell

Only the 8.0 & 10.1 have the Snapdragon.

Ketut, any chance we can recruit you to work on the 8 & 10.1?

Got it now !
It seems Tab 4 7.0 have a Marvell PXA1088 SoC
While Tab 4 8.0 could have a Qualcom Snapdragon MSM8226.

Still wondering WHY samsung always make Tab 8" better than 7" even 10.1" sometimes :p

Correct, the Marvell uses the cortex a7 architecture.

Yep, vivante here.

Sorry, I'm not familiar with android devices as this is my first one....
But I want to help if I can, so let me know which files you need and where I can find them in the device and I'll upload them.

Is it worth it to take this back and get the 8 inch? Are the processors that much different in performance? I will be playing games on this not just watching streaming video and internet browsing.

I am NOT sure Tab 4 7.0 is for Gaming because Marvell PXA1088 and Vivante GC 1000 combination seems NOT to be okay.
However Tab 4 8.0 should handle all latest games with NO noticeable lag because of the Qualcom MSM8226 and Adreno 305 (with OpenGL 3.0 :eek: ). So I would suggest you to buy this if want a gaming Tab 4.
The same situation happened with Tab 3 series where Tab 3 8" was the gaming one because of its Exynos Dual 4212 CPU and the Quad Core Mali-400MP GPU. Even Tab 3 10.1 Gaming was a bit worst than Tab 3 8" (and I had the Tab 3 10.1 P5210)

Good luck Ketut, hope you can manage to port this KK build to Tab 3 7.0 / Tab 3 7.0 Lite :good:

Well I am taking it back and getting a pro 8.4, this is a pretty slow device all around, also the screen resolution stinks for reading. I like the new interface tho. Good luck with the porting! :)

How does it compare to the new 1.6GHz quad core RockChips (Cortex A9)?

I have used information you provided here and your degas-mkbootimg tool to build a custom recovery. I am posting it soon. Thanks!

Hello
It is not accurate that PXA1088 does not support usb host
i cannot post link here yet but if you go to marvell's site and find the pdf named : Marvell_PXA1088-02_product_brief.pdf you will notice it mentions usb host.

I saw that too. But I tested with apps and it seems it's a hardware limitation. But maybe like the GT3 it maybe fixed with a custom Kernel.

    Ok so I've been rooting/jailbreaking/flashing for almost 10 years now and only have tempered into the developing fields ever so often, but I think this may be my calling..

    If you guys want to all team together on certain critera that needs to be established, I'm down for that! I'm a stubborn Italian who will not take "NO" for an answers, so when it comes to flashing custom ROM's for our beloved Tab 4 7.0's, I'm willing to put in the time and effort to get this ball rolling.. If the Tab 3 has a very similar processor, and is on CM11 then I'd believe we indeed are not that far away ourselves from Custom ROM's..

    Question 1. Where do we begin, and what has been recognized thus far?

    Question 2. What's the difference between the Tab 3 processor, and our Tab 4 processors?

    Question 3. Has this been taken to the CM site and asked for help?

    Question 4. Is it a simple case of not having the right "know-how" and getting this in front of the right person?

    Thanks!

    I´m a freak about these phones and I dedicated a yt channel to it www.youtube.com/allabouthegalaxybeam if ur interested. Anyway. I didn´t have problems when it comes to gaming or Full HD playback. And when I mean gaming I mean gaming on the built-in projector on 100 inch connected to my ps3 controller :D I played GTA San Andreas without probs like that. Only thing is that u need to cool the phone when u plan to game for longer. I really want to have CM on this phone. So my dev friend told me to do some research in order to help him on CM. I did a fundraising for the previous BEAM, so I thought of doing the same on the BEAM 2. I also looked for devs on freelancer, odesk and elance but the best "deal" for a custom CM12 that I could get was 3000 USD. And most of these people on freelancer sites u can´t trust. So sources research for this CM on BEAM 2 project started today for me. And like that I found this thread here. And the only devices that have the px1088 are listed here:

    Galaxy Tab 4.7.0
    HP Slate 6 Voice Tab 2
    HP Slate 7 VoiceTab
    HP Slate 6 VoiceTab
    and the Galaxy BEAM 2 SM-G3858 which is not listed

    Source: http://system-on-a-chip.specout.com/l/162/Marvell-PXA1088 After some short research I found no custom roms or cm versions for these tablets

    So yeah, it would be sweet if we could all work together to realize a Custom ROM for the PXA1088. There was a chinese dev which did some kind of custom rom on the BEAM 2 already. But its a bit hard to communicate with him as I dont know yet who he is :) So I assume he must have had some knowledge about the marvell SoC.
