No, I couldn't. I found no stock firmware, kernels or anything for this device. The supplier publically humiliated me after I nicely asked them to provide a stock kernel or firmware so...

Check out this build: http://www.arctablet.com/blog/forum/crewrktablets-rk3026-entwicklung-und-customroms-development-and-croms/rom-sumvision-cyclone-odyssey-7-android-4-4-2-kitkat-custom-root-firmware-20140622/

Change kernel http://crewrktablets.arctablet.com/?wpfb_dl=2373 in folder rockdev/Images before flash.

Oma, you are the Android God. Thank you so much for your help <3 I am forever in your debt

 

Edit#1: Everything works fine except the touchscreen, it seems to be inversed (Exarrow-10x10.png: I touch right side and device thinks it's left) also, rotation seems to be off (Rotation fixed with Gravity Calibration Unit)

Edit#2: Wi-FI doesn't work, power button doesn't make unlock screen appear after tablet screen goes dark. Anything I can do?

The kernel does not fit. Use an usb-mouse to go on.

Download a terminal emulator from Play Store. Boot tab fresh and try to enable Wifi a few times.

Open the terminal and type:

su
dmesg >/mnt/sdcard/dmesg.txt
logcat -d -v time >/mnt/sdcard/logcat.txt

The logs are now on your internal sdcard. Copy to PC, zip them and upload the file here.

Ok, found some hints that the tab is based on PCB ZM726C. So, same PCB as Chuwi V17pro.

Flash this build: http://www.arctablet.com/blog/forum/crewrktablets-rk3026-entwicklung-und-customroms-development-and-croms/rom-chuwi-v17pro-android-4-2-2-jelly-bean-custom-root-firmware-20140418/

And this kernel for 800x480 screen: http://crewrktablets.arctablet.com/?wpfb_dl=1874

Looks the same, except mine has a single camera. Gonna give it a spin and keep you updated. x) Also, I got the hang of the reversed touchscreen so I can operate it without a usb mouse. I'ma have some trouble downloading the terminal emulator from the store since wi-fi doesn't work but I think I can find a alternate apk to download from pc and move to SD

Edit#1: This one isn't good. Screen if off (about 0.5 cm to the left), touchscreen doens't seem to work at all, USB mouse doesn't work either (could be the mouse though, not sure, got nothing else to test it on xD ) Also, sometimes when it opens it gets stuck in bootloop (Titan > Oma, screen gets 'pixelated' > Titan >Oma >Repeat)

The V17pro build you gave me earlier I understand, but what's a Manta kernel O_o ? I'm dumb like that, sorry.

Manta = Nexus 10 kernel?
