How come everyone else have all kind of problems with it, and you find it functioning very well (except wifi, which is not weird, because each tablet that walked out of the factory has that issue)? Just a thought.

Hello

 

I installed this ROM on my Cube U30GT1 with success. Its damn good release but CWM doesn't work.....

I used arcools to install the CWM Generic recovery and when rebooting into the recovery, i get

E; Cannot mount misc, Cannot mount cache, etc etc...

I cannot do anything with the CWM and specially a nandroid bck...

If you have any ideas on this issue, it will be grateful

 

I also noticed a very weak wifi signal (From 1 to 24 Mbps instead of 54Mbps) just after installing this ROM. Before using this KitKat release, i was using/tried the stock ROM who was really unstable (tablet goes off randomly and poor performance was noticed slow responses on the screen etc etc...)

By the way, after many testing the best stock firmware for the U30GT1 is the U30GTC4_V1.05_20130812 (chinese release with the chinese crappy apps) which provides good performance and no more auto reboots or no more tablet going off randomly and screen response is also very fast

With all this stock ROM's, i didn't had any Wifi signal issues which states that this is not a hardware or antenna issue. I was starting to think replacing the wifi antenna but the wifi signal went clearly bad only after installing this KitKat 4.4... so it cannot be a hardware issue

Also, my friend who owns the same tablet got same symptoms as me. The wifi signal is very weak after installing this kitkat release but with all other ROMS, it ok..

Here comes the good part:

I MANAGED TO RESOLVE THE POOR SIGNAL WIFI ISSUE.

For guys who is having Cube Tablets and specially U30GT, U30GT1 and U30GT2 with very weak wifi signal, i think you should give a try on this.

I simply changed the wifi canal on my wifi router.... Instead of using the AUTO CANAL, i have set the CANAL Channel to 11 and MIRACLE.... The Cube Tablet is now showing a strong wifi reception and now, i'm always connected with a 54Mbps speed.

Please note that I'm located on a house in the middle of nowhere with no neighbours... There is no any Wifi signal conflict but i guess some interference are present because of my TV, Laptop and all the other electric equipment but with old ROMS, i didn't see any wifi perturbations and the reception was very good but after this Kitkat installation, the reception went weak and after changing the wifi CANAL on my router from AUTO to 11 (it also works with canal 7 and some others), the wifi reception is back to normal.

I think you should really try this since it also worked with my friends U30GT1 tablet who got the same problem in his house with his wifi router(different model)....

 

Cheers

* Cube U30GT C4

* Bluetooth problem

Thanx alot! Everithing's working much smoother. My impression is also that WiFi is working much better.

The only problem I've got so far is that Bluetooth keeps switching itself on and off. While it's on it can find devices but doesn't connect - if it's due to the fact that it switches itself off before the pairing is completed I can't tell.

 

History:

I mainly use my C4 to stream YouTube or Google Music to my Bluetooth-Speakers.

The WiFy buffering or connection was always a issue.

After flashing your KitKat I was really happy till I discovered the bluetooth problem. Since my C4 doen't make any sense to me without bluetooth I tried to downgrade to the original 4.2.2. Which worked. I could run through the initial install process, could install Apps and so on. But after reboot my C4 wouldn't react any more - stuck with a black display.

Furtunately I was able to flash your kitkat again :-) but now I'm stuck with the bluetooth problem.

 

Any ideas how to solve this on my own?

Hello,

 

(Sorry for my language i'm french)

Here is my bug with this new custom rom :

 

- When i choise a new stock wallpaper in settings -> display -> wallpaper -> wallpapers ; i get this error "Unfortunately,Launcher3 has stopped" when i set wallpaper.

 

- In landscape, the name of my icon is cut. "g, p, j , y, q" for exemple are cut. In portrait no problem.

 

- If i set up a wallpaper from my gallery in landscape it's ok. But when i rotate to portrait and to landscape, my wallpaper is oversize. 

 

-> Image 1 : Wallpaper OK. (You can see the bug with the name of icons)

-> Image 2 :  Wallpaper adapt to portrait. No bug with police.

-> Image 3 : Wallpaper is oversize

Update:

This is probably outdated to the most - but maybe some help to some:

 

I manged to install the Cube 4.4.1 Firmware (U30GTC4更新4.4系统_V1.0_20131226.zip) replacing the ROM from here.  

Found it here:  info  download (some translation plug-in helps)

Everthing (specially bluetooth) working fine up to now.

Changing from chinese to german (in my cas) was no problam - such as in the shipped version.

For those who are looking for the 4.2.2 version: download

Hi

As you all saw, CWM doesn't work with this 4.4.1 KastyRom on the U30GT1 C4 tablet.

You will get the "E: cannot mount 'partitions'" messages

 

I managed to resolve this issue by installing the IFIVE 4.4.2 CWM by manu PC Recovery. This CWM is now present in arctools.

You can install this CWM 4.4.2 on the 4.4.1 kasty Rom. It will work without any problems.

I can now do nandbackups and i'm really happy

Cheers

CWM

 

A good manip for me

1 install kasty-cube img

2 use RKAndroidTool

   all sqares unchecked

   on line "recovery" chose CWM_recovery_ifiveX2_442.img & check this square

   press flash rom

   after reboot a good 6 recovery is installed

3 to go to recovery

   use arctools apk

   or once cube down press v+ & start buttons 

   wait some seconds

   release strat button

   release v+ button

  that's all

   but arctools apk is the best

4 install what you wish from DJ 442 kernels

 

regards

 thx to admin, dj & others

Hi guys

May 20132 I bought a U30GT2 CUBE by Hongkongeek
interesting caracteristics
excellent use

February 2014 battery hs
then I received a nonfirmware battery (11000 ma, 7,4 v)
I open the cube
it is a badly recycled one
all the screws are maintained with compound cement
all screws screwed on soft plastic parts
all flat cables are not yet welded but scotched
battery connectors and screen flat cable are scotched with the same scotch
it is impossible to re screws the cube parts
two centring pins of the alu belt re welded

I open a 49 € tablet
no scoth
connectors everywhere
all screws on metalic parts

the cube caracteristics paper is excellent
the cube itself is an obscene material
All problems on the cube come from the very bad quality of the material

A GOOD ADVICE I DON'T BUY ANY CUBE MATERIAL, CUBE IS NOT A FIRM FOR ME
my job research, development, quality, validation engineer
