I actually switched from the rooted 1.05 firmware to the original 1.05 for the U9GT3 posted on the Cube website, and it fixed all the issues I was having. Â Wi-Fi now works full speed with no lag, and no longer drops when the tablet goes to sleep. Â Plus it's generally faster, although the clock speed is still listed as 1.4 GHz instead of 1.6, so it must come from Cube and not the rooting. Â Antutu benchmark jumped from 9000 to 10500. Â
I haven't tried the U9GT3-S variation because I don't want to mess around the brick the tablet by mistake. Â

Here is a custom rooted firmware version of the Android 4.1 Jelly Bean based on official version 1.05
Features:
- root with latest SuperSU 0.99 (free version)
- writable /system partition
- removed most Chinese and unnecessary applications
- increased space for application (/data partition) to 2 Gb.
- update busybox to version 1.20.2-cm9

Rooted custom firmware for the CUBE U9GT3: kasty-cube_u9gt3-41-105-rooted.zip
Use Rockchip Batch Tool version 1.5 to flash the firmware, don't flash using the "sdcard" method.

Please report any problem with this firmware, I can't verify this custom firmware works as I don't have a Cube U9GT3 to test it.
works perfectly on my u9gt3s. thanks
