Just released: Cube U23GT official firmware version 1.04 (2012/10/30), it seems to be mainly a kernel update:

Linux Kernel: Linux version 3.0.8+ (eyes#0001@eyes) (gcc version 4.4.0 (GCC) ) #480 SMP PREEMPT Sat Oct 27 15:20:14 CST 2012
Here is a custom rooted firmware version of the Android 4.04 ICS based on official version 1.04
Features:
- root with SuperSU 0.96 (free version)
- writable /system partition
- removed most Chinese and unnecessary applications
- increased space for application (/data partition) to 1.5 Gb.
Rooted custom firmware for the CUBE U23GT: kasty-cube_u23gt-404-104-rooted.zip
Using Rockchip Batch Tool version 1.5 to flash the firmware.
Please report any problem with this firmware, I can't verify this custom firmware works as I don't have a Cube U23GT to test it.

hi, i'm new to this forum, just got my cube u23gt. I just want to clarify if its normal with this unit that when I press the power to put the tab to sleep & press again after about 20 secs, I wont be able to awaken it in one press of the button. it takes 5 to 6 short & long press to turn it on & when it does, it boots like its been shut down. but if I set the leave wifi on to always & press the power button for the tab to sleep, I can re-awaken it even after more than 20 sec of sleep. doesn't bother me much except that the batt. will drain coz of the wifi being constantly on. I already tried upgrading the firmware to 1.04 w/c I got from the cube website (as advised by merimobiles) but the problem still persist. Is this a defective unit?

Hello
I can ask you for help with my cube u23gt. I have bought it from resseler cube-stores.com. It was OK for 3 weeks, but now its frozen every time, when i try to play video (from sd card or from network, or from TV application or youtube - thats all is the same - tablet is completely frozen, when i click on it). I am not able to reset device using vol+ and pwr buttons, the only way is
reflash firmware with RKbatchtool, i use your kasty-cube_u23gt-404-104-rooted.zip .Then i can switch the tablet on, but when i try to play video, its frozen again. Could you tell me another way, how to bring device to life? I am not sure about right method to reset device. Thank you .
A good possibility is to reflash your firmware using the Restore option in RKBatch tool.
If you can't get your device to enter in flash mode, you can also use our program ArcTools: download and install the application, then use Reboot button, select "Reboot Bootloader", confirm Grant option in SuperSU and wait for the device to reboot. This way of rebooting in flash mode will only work on a rooted firmware such our kasty custom firmware.
After the device has booted to bootloader, you should get the green square in Rockchip flasher. Please read our Rockchip flashing guide for more details on how this procedure works. Using ArcTools to enter in bootloader mode takes you directly to step 3 from the guide.

There is a firmware 1.04 from 2012.11.09 at cube website http://51cube.com/ch/DownShow.asp?ID=87
is it same as 1.04 posted here?
Changes transalted by google:
1. Optimization problem can not wake up dormant standby;
2. Optimize part machine flash machine failed.
Well, the 1.04 firmware I got from Cube is 1.04, dated 2012/10/30 as first post says.
I'll download this "new" version and check if it's a re-release or something new, it's quite frequent that Cube re-release old firmwares just changing the publication date, I have no idea why
Cheers.

Hi admin, thank you for advices how to reflash the tablet, but its no my problem. I have made successful reflash to casty cube 1.03 and 1.04 many times, but evetytime tablet worked good (i installed apps from play, used skype videocalls, office, browser, i.e.), but when i tried to play video, it was immediatelly frozen, i was able to switch it off by pressing pwr button for 10 sec, and then it does not start (i tried start for many times - there was always only the cube - nocube - no passion on the screen for long time), Then i reflashed firmware and it worked again - until i tried to play video. This cycle i did about 20ty times.
And now read carefully please: Im not sure about right procedure to enable recovery mode, when I do flash, I connect the USB to both tablet and PC at first, and then i press pwr+vol+ button together - it works (RKbatch device got green). When i tried to enable pwr+vol+ and then connect USB, i get only dead android on the screen and computer did not find any device. Also, how is it? There are many people on the internet, who says it works. But I have to use another method - strange!!!
Do you have downloaded the original firmware from 51cube? Could you give me a link to download it from you, please? It is impossible for me to download it from 51cube.com - it really does not work. This is the last chance for me to try original firmware.

Note: Video Playback seems to work great in my tablet ; also youtube.

Hi foox2k.
I am pleased you are satisfied with your cube u23gt, I was too, but only for 3 weeks, I mean this tablet is very nice and powerfull, but now , in my oppinien, I have hardware problem with Mali400, because I canot play any video, when I try its completely frozen. I mean, that it cant be SW problem, because a tried 3 different roms and always there was problem with playing video. I will try to send it back to china - cube-stores.com. Good luck with your tablet.

hi foox2k, I just want to ask if you experience also that when I put the tab to sleep, & press the power after about 20 secs, I wont be able to awaken it in one press of the power button. it takes 5 to 6 short & long press to turn it on & when it does, it boots like its been shut down. but if I set the leave wifi on to always & press the power button for the tab to sleep, I can re-awaken it even after more than 20 sec of sleep. doesn't bother me much except that the batt. will drain coz of the wifi being constantly on. I already tried upgrading the firmware to 1.03 & 1.04 w/c I got from the cube website (as advised by merimobiles) but the problem still persist.
