Just for testing purpose:
I did a build for RK903 wifi, which is here.
It works good on Cube U30GT2 with this model fix (install via CWM): http://crewrktablets.arctablet.com/?wpfb_dl=1823
Try it with the Cube U30GTC4 kernel (before flash replace the kernel in folder rockdev/Images): http://crewrktablets.arctablet.com/?wpfb_dl=1866

Hi Oma,
why should we use the U30GTC4 Kernel instead of this one you posted before? --> http://crewrktablets.arctablet.com/?wpfb_dl=1817
is there any difference?
- Thanks

Yes, kernel is for U30GTC4 (also named U30GT1), which has at least an other resolution (1280*800).
I'd like to find out if we can roll-out the latest KK build on the U30GTC4.

Hello all
I own a U30GT C4 and i loaded the firmware, i can report it has a few Bugs! Bluetooth will not connect to any devices also the name of the tab got renamed somehow, i have tried to rename it back again to U30GT C4 but it wont let me.
also on the main page the app names are cut off a bit at the bottom of them.
Thats it so far
will report if i notice any others.

I did previously have jelly bean and the internet wifi was working fine, but the tablet kept on freezing, so I installed this kit kat firmware. But one of the issues that I find is that the internet keeps on disconnecting on my tablet. I tried "wifi fixing" programs and none work. (my router/laptop setup is fine with wifi). Could someone point me to other firmware that is not on the pan.baidu.com - that is in chinese and once you login with this info on this page http://www.cube-tablet.com/download you get about 12 boxes to click on. I tried to translate but its not working for this particular page. I cannot use the u30gt-w or u30gt-h firmware. Mine is the u30gt-c4h version.
I have another problem:
My microphone and headphones work, but the speaker doesn't work. Its a hassle opening it up with those tiny screws, so should I bother and check for loose speaker wire or is the speaker dead?

I fixed the wifi. This is what I remember doing:
Installed a "reboot" apk,
Went to cubes recovery and wiped cache, wiped data and factory reset,
Reinstalled the firmware with the "upgrade" option.
Installed "xposed framework" (be careful - this is risky software and your cube could go into a bootloop). Then I installed the module "Xposed Wi-Fi Deep Sleep".
Go to settings, wifi - then go to the right hand side with the three dots - click on it and you will find menus there. Click on advanced. These are ticked: "Network notification", "Scanning always available" "Wi-Fi optimization". The others are all unticked. Go to the "Keep Wi-Fi on during sleep" option and changed it to "never (increases data usage)" option.
Now the internet doesn't drop out anymore. Now the signal is "excellent" from near the modem, and "good" from my room which is further away, with no dropouts anymore.
Re: Yes, it worked for a few days, now its back to its old ways of not connecting/working anymore. So I installed the chinese firmware from page 6 and bluetooth and wifi work now. I don't like this firmware because it has parts written in chinese for example the keyboard (not the important parts though), but I would rather have the wifi and bluetooth working as I am using a bluetooth speaker for the sound as the speaker from my cube doesn't work (hardware problem).
