Bigben, are you referring to this download U30GT四核豌豆1固件（安卓4.2系统Beta版） ?

I don't think it's related to the good old U30GT like -H or -W models but a new one, as Google Translate says:

"The firmware is only applicable to quad-core peas , product model is displayed in the system settingsU30GT C4 machine refresh"

Still, I'll download it and double check if this firmware is intended for RK3066 devices or not.

Cheers.

I've downloaded the firmware mentioned in post #2, I do confirm it's made for a model named

U30GT C4 which is actually running on RK3188 architecture, so it's unlikely to work on older U30GT (RK3066 based) tablets.

Not much traffic here, but have successfully loaded and ran (2) different flavors of 4.2.2 on my CubeU30GTH dual core. (1) was an AOSP 4.2.2 (Dependable and currently running) (2) was a CM10.1 4.2.2 (more options and really the sweet one, BUT has stability issues, yet works better if you back off on CPU tweaks from 1.6 to 1.4. CHECK them out at "Crew RK Tablets" and many Thanxs to OMA (O'Master). Believe I also saw Netlar mentioned in the credits, thanks Netlar.

New update available for the cube u30gth dual core rk30. This is the sweetest build to date yet. All works except you will need to build with the cwm 6.0.3 recovery image, 6.0.5 image still won't load on this cube build. Also works with the 308 or the 3066 kernel. Stability is much, much improved over last build. The AOSP 4.2.2 works very well also, but love this CMod. Thanxs to the entire team.

There is only one thing left to find, and that is some ad hoc support.

If anyone knows how, leave a post. Thanks again to the rktablet crew.

cappybob please tell me which kernel i have to download (i supose voyager).

I have ICS infected 4.0 rom with 308 kernel and CWM 6.0.2.8.

So i put my cube to recovery mode and then use the rkflashtool to flash the RK30 cROM.

then push again the CWM 6.0.2.8 or 6.0.3??

DallasCZ really not familiar that much with android. Linux yes, windows yes, mac yes, but android systems are new to me. Everything I have been able to work with and figure out come from http://crewrktablets.arctablet.com/. They have many kernels originals and homebrew for many, many tablets. They have operating systems for JB 4.1, JB 4.2, and now appearing JB 4.3. they have several flavors AOSP, CMod, open framework, and etc. My tab u30GT-h (RK30) will only use CWM 6.0.3.1 though builds use CWM 6.0.5.1. Builds using rocktools 1.35 use several images to build in the packages. You need only use a recovery image (CMW) which yours recognizes and your proper kernel img, flash into cwm and install other necessary zip files following directions included in the downloaded package. Latter, hope this is not confusing.

Yes, and currently running 4.2.2. need to down load aosp or cmod 10.1 from http://crewrktablets.arctablet.com/. I like AOSP more stable for my uses. Will try to get links set up for software for you. The package download with instructions are the program http://crewrktablets.arctablet.com/?m=201304 . Link worked, download version 3.2, and the other 3 files (cmw 6.0.3.1 recovery image and the two nand_fix.zips) Then at the top of page goto downloads drop menu down and go to kernels (stock) find the u30gth_308 down load that also. You should have (5) files now for your build. Install the two nand fixes to you external sd card.

INSURANCE: Your original UPDATE.img and rocktool v1.5 (MUST HAVE INCASE SOMETHING GOES BAD)

Now the fun part

1) unzip crom v3.2 read instructions

2) open and install rocktool v1.35 to install rock chip usb drivers ( if you have updated,you have these already)

3) unzip (2) replacement images (1) kernel and (2) cwm recovery to desktop

4) in rockdev keep drilling down until you reach image folder (open)

5) delete the listed kernelS (both) and recovery images and replace with the 2 on your desktop

6) change will be no second kernel to load we will use the right one now start with eraseIDB click on, wait for ok

7)clear OK from IDB now hit run (build will install new OS and check for mistakes)

8) will now open up cwm window (install two zips you had already loaded on your external sd card)

9)wipe data and user

10)reboot will take a few minutes

Messed it up did you, won't do anything have a fix.

If you have your insurance you are fine.

Unzip original.image to desktop (UPDATE.img)

run rocktoolv1.5 load update.img and UPGRADE

wait for boot and try again.

Spider you will need to install from CWM an intSD_ nand_fix. http://crewrktablets.arctablet.com/?page_id=433. Download to downloads folder to access this file in CWM. Actually as you sit right now, your nand is your external SD.

If you did install this and computer does not allow access. Goto settings, tab storage, upper right corner tab, usb connect menu check Media (MT*) and on computer view files to show both int and ext SD. May need to uncheck debug setting in development.
