Problem solving
I ask everyone who reports problems with the tablet - be sure to specify:
  • firmware version;
  • what actions were carried out (problems appeared / disappeared / remained)

1. how to reset?
* Hold the Power button for 10-20 seconds and the tablet will reboot itself
2. how to enter rekoveri
* 1 way - Disconnect all cables from the device (also charging), turn off the tablet completely, press and hold VOL + andconnect without releasing the button VOL + charging cable, and hold until the CWM screensaver appears.
* 2 way - hold down the "volume +" and "power" buttons (simultaneously) and hold until the CWMrecovery logo appears (seconds 30-40)
3. In sleep mode, wi-fi falls off, although the settings are set to never do this
* 1 method describedhere
* 2 way - if you have the firmware from ImaSoft in CubeControl set "Do not give off Wi-Fi" (4.1.1 does not work)
4. in Android 4.2.2 firmware increased battery consumption "Mobile network level"
partial resolution of this issue is describedhere
5. On firmware 4.2.2 v.2.04 from 20130810 and all firmware based on Kernel (kernel) # 0037 SMP PREEMPT there is an increased battery consumption

I had a similar problem solved the problem by replacing the USB cable that came with the tablet.
By the way, in the device manager, I did not choose a cube but an unidentified device

Thank you, it really helped, just according to the instructions in the header of the Power + Vol + pins and the tablet was simply buried in recovery. I thought the driver needed to be installed. Now I put in the phone with the ox + and the tablet was immediately defined as Class for Rockusb devices, and was defined in RKBatch.

/ Proc - virtual file system that contains all the information about the Android system, including core processes, configuration parameters, hardware information. All files in the / proc are also virtual, and does not actually take place in the memory (so the size of the file is 0 bytes), the operating system creates them "on the fly" when a user tries to read them. Any manipulation in the folder / proc are only possible with root privileges. / Proc file system can be viewed as an interface to the internal data structures in the Android kernel. This interface allows you to obtain information about the system and change some parameters to the kernel at the time of the Android operating.

Many programs collect information from files in / proc, format them and output the result to the user (top, ps and others). There is a special folder / proc / sys in the / proc file system. It allows you to view kernel parameters and change these parameters on the fly without rebooting the system.

The virtual system / proc files are not intended to be viewed with a regular text editor, as this may violate the integrity of the kernel data. To do this, use the echo and cat commands.
/ proc / nnnn - virtual folders with numbers correspond to each process running in the system.
/ proc / net is a virtual folder containing information about networks.
/ proc / net / dev is a virtual file containing information about each network device.
/ proc / sys is a virtual folder containing kernel configuration parameters.
/ proc / meminfo is a virtual file containing memory information (to view this information, type the following command: cat / proc / meminfo).
/ proc / version - a virtual file containing information about the Android kernel version (cat / proc / version command).
/ proc / cmdline is a virtual file containing information about the parameters passed to the kernel during the boot (command cat / proc / cmdline).
/ proc / cpuinfo is a virtual file containing information about the processor.
/ proc / loadavg - a virtual file containing information about the average processor load; its information includes: CPU utilization in the last minute, in the last 5 minutes, and in the last 10 minutes, as well as the number of current processes.
/ proc / stat is a virtual file containing information about statistics related to the previous system load.
/ proc / uptime is a virtual file containing only two numbers: how many seconds the machine has been working and how many seconds it has been idle.
/ proc / devices - a virtual file containing information about all configured and loaded character and block devices at the moment.
/ proc / ioports is a virtual file containing information about input / output ports (I / O communications) used by devices.
/ proc / filesystems is a virtual file containing information about all file systems that are supported by the kernel.
/ proc / mounts is a virtual file containing information about all mount points used in the device.
/ proc / partitions is a virtual file containing information about all sections.
/ proc / swaps is a virtual file containing information about all swap spaces (swap space).

/ sbin - folder containing executable files of programs that are designed to manage the system itself. Example: ifconfig, man, mdev, vconfig.
/ sdcard - a folder containing files and folders on the SD memory card (if installed).
/ sys folder containing the actual system configuration at the current time. / sys is very closely related to udev if you connect (disconnect) devices, the contents of the / sys directory change dynamically. You can look at an example. Run the ls / sys / bus / usb / devices / command to view the current usb devices in the system. Now connect the flash drive and execute the command ls / sys / bus / usb / devices / again. You will see that now there are more devices.
/ system - a folder containing system files and folders with data and everything necessary for the operation of the Android OS.
/ system / app - a folder containing system applications (SMS, phone, calendar, settings, etc.), as well as applications installed by the device manufacturer (branded widgets, live wallpapers, etc.).
/ system / fonts - folder with system fonts.
/ system / media - a folder containing standard melodies of calls, notifications, alarms and interface sounds, as well as boot animation (bootanimation).
/system/build.prop - a file containing a huge number of settings, such as the density of the screen, the delay time of the proximity sensor, the wifi control, the name and manufacturer of the device, and many other parameters.
Now in firmware 4.4 some of the "main" system applications have been moved to the folder/ priv-app (Calendar, Contacts, Settings, SystemUI)

Utilities for disassembling and creating firmware
RKwinTools from vin2809
The tool for working with firmware RKwinTools is designed to disassemble and create firmware devices based on RK29, RK30 and RK31.
RKwinTools allows you to:
select the source ROM-file for processing from the list of available;
unpack and pack ROM-firmware in the format "RKFW" and "RKAF" with automatic format detection;
unzip boot, recovery. Both "ANDROID" and "KRNL" formats are supported with automatic detection;
package Boot and Recovery images with the choice of the type of the final image (KRNL or ANDROID);
unpack and pack a Kernel image;
unpack and pack a jaffs and ext2-ext4 System image;
convert a compressed System image of type sparse to ext4;
initiate a ROOT into the system image;

RKwinToolsMod by And_pda
What can be usefulRkwintoolsmod
- to unpack the firmware file (RKFW format file (* .img) or archive of the form * .tar (rar), the latter is relevant for example for Samsung devices)
- for unpacking the contents of the firmware (system, kernel, recovery, boot images)
- to build images from unpacked content (system, kernel, recovery, boot images)
- to build a full firmware file format RKFW (* .img)
- Added support for building system.img in EXT4 format (new menu item)
- Updated ImgExtractor utility (current version 1.3.0), used to decompress system.img in EXT2 \ EXT3 \ EXT4 \ SPARSE \ YAFFS2 formats
- Added the introduction of ROOT for Android 4.2.x (a new menu item, for Android 4.1.x, a separate menu item, based on previous data), the su binary is searched in the \ xbin and \ bin folders
- Added to obtain information about the image system.img (new menu item) - formed system.info file with the information from the superblock, the full information is still only available for images in a format EXT2 \ EXT3 \ EXT4, for SPARSE format will be recorded in error system.info (in this case, if you still want to get information about the superblock, you can convert to the EXT4 SPARSE (menu item 7, the size of the resulting system.img be much larger), replace the original in system.img Unpack \ Firmware \ Image \ to obtain and re-request information.
- The method of forming the system image has been slightly modified - now after creating, converting and checking the image, a request appears to confirm the procedure for reducing the image size (RESIZE), it is simply not always RESIZE that is appropriate - the image is collected with a minimum excess and spend time reassembling, winning about 10 megabytes frivolous. But the decision remains with the user.

RK_ParamEd
RK_ParamEd file "calculator" Parameter for rkxx. Allows you to edit all the parameters of the file:
informational;
command line options;
section options.
Two words about how memory works in mobile devices. Yes, just like in any computer.
In the BB, there are two types of memory available for the average user. This is a random access memory (RAM) that stores current data and codes of running programs. It is ALWAYS cleaned when the computer is turned off. And the memory for permanent data storage (ROM), in common parlance called "hard drive", the data on which REMAINS after power off.
The mobile device also has RAM and ROM. In modern devices, RAM has a size of 256MB-4GB. ROM is NAND-memory, having a size of 4-64GB.
We write the firmware to this “hard drive” (NAND-memory), which may contain several sections: the operating system (OS) itself, user programs, data of both the OS and the user, etc.

To partition NAND memory into sections, i.e. For markup, devices on RKxx chips use a Parameter file that stores all the information about the sections: name, size, offset, and access rights.
Although it has a very simple format, it gives users a lot of difficulties when working with it. To facilitate your work, the application RK_ParamEd is written - the firmware parameter editor for RKxx chips.
When repartitioning the memory, it should be noted that the sum of the sizes of all partitions is equal to the total size of the NAND memory. That is, if you, for example, increased the size of the system partition, the size of the last user partition, which is located at the end of the memory and takes up all the space left after the other partitions, will decrease. Or you need to reduce the size of another section to save the user.

The problem with Wi-FI .. after leaving the hibernation of the tablet wildly slows down and does not respond for 10 seconds - by all mail, social. networks and updates will not dive.

Jazzman_88 @ 04.26.2013, 00:06*
Users of this device, share how the problem is treated: wi-fi falls off in sleep mode, although the settings are set to never do this! Bug firmware or maybe fix?

Jazzman_88 @ 04.26.2013, 15:31*
I use Skype on the tablet, and here it is with the screen off in 2-3 minutes it flies out of the network. When you unlock the screen, it is clearly visible that the wifi is not active.

Unfortunately, there are still Wi-Fi disconnections. Perhaps the problem will be fixed in new firmware, for now it is recommended to use third-party software, for exampleREGPON WiFi KeepAliveWhen using it, the battery consumption is slightly increased.

Advanced wifi lock- Fix the problem of automatic reconnection to a Wi-Fi access point after sleep.

Wifi Fixer - is a service that automatically maintains a normal WiFi connection, while consuming few resources. ( recommended )

After installing the update, users will receive a virtual keyboard with the ability to enter text with gestures, an updated notification system and some improvements in the operation of the device itself.

Unfortunately, the manufacturer has not fixed a bug in the Wi-Fi operation, in which the tablet loses its connection with the router.

CUBE U30GT2 Android4.2.2 (Evalution) _20130507



Rep: (178)
Question to the owners of the cube with the installed firmware Cube U30GT 2 (1.05) 900 supersport ROM
Rummaging a bit in the firmware found several options for the file "parameter"
Attached Image

Reading onthe site900supersport stumbled upon an explanation
Attached Image

If you try to translate:
- 2 gigabytes of application space seems large at the moment, but I think that they will be satisfied with another, I created three more parameters files for 4 GB, 6 GB and 8 GB.
- To change the size parameter you need to add the parameter file from the archive to the ROM folder. From the flash tool, check the box next to the parameter and go to the ROM folder and select the parameter file. EraseIDB and then flash ROM.

Now a number of questions arise:
- which of the tabs to check the box?

- where do these 4 GB, 6 GB and 8 GB with RAM or SD come from?
file difference
