This firmware is designed for the Cube U23GTC4 model, tablet with serial #: U23GTc4XXXXXX) If you own a U23GTC4-W tablet (serial #U23GTc4WXXXXXX) please use our specific firmware.

 

Here is a custom firmware for the Cube U23GT quad-core (U23GTC4) based on a Rockchip firmware version 1.06 published 2013/06/05.

 

(U23GT四核寒冰_V1.06_20130605.rar)

 

Build information:

Kernel: Linux version 3.0.36+ (cb@cb-eyes) (gcc version 4.4.3 (GCC) ) #374 SMP PREEMPT Wed Jun 5 16:15:43 CST 2013

Android 4.1.1 Jelly Bean:  rk30sdk/rk30sdk/rk30sdk:4.1.1/JRO03H/20130413.175606:eng/release-keys

 

Custom firmware features:

  • root with latest SuperSU version 1.51 (free version)
  • removed most Chinese and unnecessary applications
  • Google Play Store fixes so more application are visible/compatible
  • updated busybox v1.21.0.git (2012-11-29)
  • Unix like init.d boot scripts support, more details on init.d scripts here
  • changed permissions on external sdcard to allow write access
  • increased storage space for applications (/data partition) to 4 GB 
  • Android keyboard application from Cube U30GT2 firmware
  • NEW! kernel modules (cifs, tun, lan, serial, xpad) compiled by Oma & Crew RKTablets, thank guys!

Download:  kasty-cube_u23gtc4-411-106-rooted4.zip

Flash the firmware with Rockchip Batch Tool 1.7,  use Restore button.

 

Please report any problem with this firmware, I can't verify this custom firmware works as I don't have anymore a Cube U23GTC4 tablet to test the custom firmware.

Looks like the substitution keyboard from the Cube U30GT2 doesn't work as expected.

I'll soon rebuild a new firmware with the stock Asian keybard (should be compatible with non Asian as well) or find another keyboard option.

What you call the wireless network card is the internal WiFI on your tablet ? that's strange, it should work right away. Have you flashed using Restore button in Rockchip Batch Tool ?

Cheers.

Thanks for the quick reply.

 

Yes it is the internal WiFi card is not activating when you toggle to turn it on it try's and then turns off again.

I have tried both ways, first the upgrade option and then the restore option both have the same results, keyboard issue and WiFi issue.

 

Thanks

I'll have a second look at the WiFI problem, but it doesn't seem to be related to my custom firmware Confused

I hope Cube hasn't made different hardware versions of the U23GTC4, that would require different firmware.

About the keyboard problem, here is a new custom firmware version with the original Asian keyboard kept:

i have tried the new firmware that you have provided, keyboard work fine now, but still an issue with the WiFi, i have downloaded the firmware from the manufacture website and this does not solve the problem either, i have email my supplier to see if they can suggest anything or give me a link to firmware. This is the serial number of the device U23GTC4W16GBW13293330254.

 

What do you think could be the problem.

 

Thanks

The problem is probably that the device you have is probably equipped with a different chipset than the one designed in the firmware Cube is offering. This kind of problem happened a while ago with another Cube model, I think on the early production batch, the manufacturer did last minute changes with the components, while not fully tracking this in the firmware. The best thing to do is what you did, ask the vendor/manufacturer for the right firmware for your model, giving all details about serial and where/when you bought it.

Please let us know when you have some news. In the worse case, it might be possible to fix the firmware on our own, but that will require some time and it's a kind of trial/error process as I don't have this device here.

Cheers.

Well, pretty much what I expected. It's probably the WiFI driver failing to load.

We could have a look to investigate further with debug logs (from logcat and dmesg) if the manufacturer doesn't answer quickly.

Cheers.

What I see on wanden page is a custom firmware you need to pay for, which is more or less what we offer for free. Sure, they have a few extra features and pre-installed program, question is, is that worth the price ? I can't really answer, but I'm sure we can build a similar firmware. Also note it's for the Cube U30GT2, it won't work on your U23GTC4.

I'm waiting for your feedback and download link for the manufacturer's firmware.

Cheers.

I don't know if you can do this, what i was thinking that might help is if i buy one copy could you adapt it and make it you own for the following models i have a range of cube models that i would like it to go on.

 

Here are the models that i have

 

U23GTC4

 

U30GT2

 

U35GT2

 

U9GT5

 

Thanks
