Was searching around and it seems Oma managed to create one here:

 

http://crewrktablets.arctablet.com/?p=4316

 

It only states that it's tested working for U30GT2 too, but was wondering if anyone can share how to exactly update from KK to LP with this ROM?

 

TIA!

 

UPDATE: Sorry! I didn't notice there's a 5.0 thread already. Just followed Mark06' post from that thread:

I think it's a bit like this:

You need following downloads:

Kernel: http://crewrktablets.arctablet.com/?wpfb_dl=818

loader: http://crewrktablets.arctablet.com/?wpfb_dl=1631

lollipop v1.2: http://crewrktablets.arctablet.com/?wpfb_dl=2246

Unzip all files. Start up rkandroidtool and select the kernel and the loader you downloaded(see links above). The rest you can select from the lollipop file extracted. All except backup you have to select and add.

Run the proces. After done the tab should reboot into cwm menu. Then select reboot and press twice no. Then wait for about 7 minutes and the screen should show swipe menu.

 

Since I came from a KitKat ROM, had to do the following steps first:

1. Change from Gen2 to Gen1 loader using Oma's file (see Instructions.txt inside archive): http://crewrktablets.arctablet.com/?wpfb_dl=1631

2. Download Alpha Build 1.2: http://crewrktablets.arctablet.com/?wpfb_dl=2246

3. Extract Alpha Build 1.2 to a folder, and replace kernel.img with the one from Mark06's link above: http://crewrktablets.arctablet.com/?wpfb_dl=818

4. Download either the DYNAMIC parameter file or 32GB parameter file and replace the one in rockdev folder as well:

DYNAMIC: http://crewrktablets.arctablet.com/?wpfb_dl=2244

32GB: http://crewrktablets.arctablet.com/?wpfb_dl=2034

^ The 32GB version was the one that worked for me. Just adding the DYNAMIC version in the event that this is a case-to-case basis

5. Run AndroidTool using the steps indicated in Instructions.txt off of the Alpha Build 1.2 archive... and voila! After a factory reset and ~7 minutes you're on the swipe menu!

 

All credits and thanks to the guys over at the Lollipop port thread, especially Oma and Mark06!

Maybe a factory reset and when rebooting again, select no twice. And it normally takes 7 minutes to get in logon screen.

Mark,

I managed to flash it finally to 4.4.2 but the brightness of the tablet has decreased quite a lot. In another forum this problem was  raised and the solution was to flash a kernel file given on that forum. How can you only flash a kernel file?

I see a lot of activity on this site but would prefer who ever comes up with flashing etc should make a video as well to illustrate things better

mechtrix, it's not really difficult. You need first to install the adb/rockchip drivers for the cube. Next start up androidtool and only select kernel and choose the kernel image of your likes. Then if you all ready have installed a rom, you have to activate usb debugging and connect it to your pc. Then you choose either to flash it or the switch option, if flashing isn't working yet. And voila, your kernel is being installed.

Then, yes a video from youtube might be easier. I will take a look into that. What you also can do to make the image brighter is install dimly. With that app you can alter completely the brightness settings of your cube. Plus it's freeware.
