Inverted screen

Hi Oma,

I hope that you can help me, I have managed to falsh your rom to my Acho C905 and it looks awesome.

But the problem that I have is that the screen is inverted.

Touching top left or the screen activates the top right and vice versa.

The calibartion tool for the latest versio of your rom fails each time.

Any ideas how I can fix this??

Many thanks

Hi Oma,

I'm coming from the other post but it looks like this one has more activity, I'm trying to improve my "iJoy Andromeda" Tablet with Androids ICS 4.03. This tablet is a rebranded PiPO DS970. and it looks like very similar to the Technaxx BigTAB. The outside is the 100% the same, buttons, screen size, etc, and is also based on RK2918, the only difference is BigTAB processor is 1,2Ghz instead of 1Ghz

These are the specs of my tablet and a link to the firmware:

http://www.i-joy.es/download/tablet/Andromeda/ANDROMEDA_firmware.zip

Tablet PC (Mobile Internet Device)

● Display: 9.7" digital TFT, resolution 1024*768(4:3),IPS technology with wide

viewing angle and low power consumption , capacitive touch screen( 10- touch)

● CPU: Rockchip 2918,1GHz,ARM Cortex A8

● SDRAM: 1GB DDR3

● Internal storage: 8GB/16GB/32GB (optional)

● External storage: with Micro SD slot to support external memory up to 32GB

● OS: Android 4.0

● Built-in 2M pixel front Camera & 2M pixel back camera

● With WiFi 802.11b/g/n

● With voice recording, speaker, G-sensor

● With USB host, supports USB device directly, such as keyboard/mouse/USB drive/Lan...

● Supports external USB 3G dangle

● Battery: 4000mAh by 7.4V

● With HDMI output

http://www.pipo.com/product.php?id=74

I succeeded installing OMAs Jelly Bean 1.2.2 with Technaxx BigTAB kernel.

The problems I have right now are:

- I cannot download anything from Play Store, it gives me an error. Wifi is working because I can access Play store and check contents but downloading doesn't work. I will check it later, reseting all Play store configurations... SOLVED

- Brightness works

- Rotation Sensor doesn't work. I'll try with some of your patches..

- Processor looks like is working overclocked to 1,2Ghz :S Maybe I can reduce the speed to 1Ghz with a CPU util..

- Rear Camera works, but cannot use it because tells me I need to use an SD card?? Is there any option to change default storage location, so at least I can use the camera?

- Pending to test:

- Bluetooth

- Front Camera

- HDMI

Is it posible to create a kernel for this tablet? I would like to avoid overclocking..

Thanks for your work!
[Miscellaneous Android Development] qwertyu123:
I could solve everything but:

- Rotation Sensor doesn't work. I'll try with some of your patches..

- Processor looks like is working overclocked to 1,2Ghz :S Maybe I can reduce the speed to 1Ghz with a CPU util..

Despite this OMA's work is great! Thanks!

Sounds like the wrong kernel. There are some hardware revisions: http://xdaforums.com/showpost.php?p=35651180&postcount=544

[Miscellaneous Android Development] qwertyu123:
Many thanks for the kernel, I just tried right now.

CPU is still clocked to 1,2Ghz. I'm not sure if my original 1Ghz can do 1,2Ghz with no problems. Maybe some configuration from CPUfreq is forcing it to go 1,2Ghz? If so I will restore everything so I have clean install.

Other issues I found with Techtrax kernel was that 3D performance was awful (compared to stock) but with the iJoy kernel you just prepared now is like stock. Great!

Bluetooth still cannot be activated with old or new kernel. I will check later which solutions are available for this, but it is not so important for me as I don't use it so often.

I could solve the rotation sensor problem as well applying your patch to increase sensibility CrewRKTablets_CM10.1_sensor_X=Y_Y=-X_Z=Z_sensitivity_1000000.zip

I'm so happy because there was absolutely nothing on the internet for the iJoy Andromeda (PiPo DS970) and the stock ROM is a disaster (constant app crashes).

With your ROM the tablet looks like new!

When I finish tuning the ROM for the iJoy Andromeda I will post the exact patches I used so it can be helpful if anybody has this tablet.

[Miscellaneous Android Development] midiboss:
Can't enter CWM

I've tried to install ROM to Prestigio PMP5097C. Seems like I've done a major mistake not inserting correct kernel or disabling kernel option in RKAndroidTool.

Now my device manager displays PMP5097C device as Loox (Portable device). There's no way I can enter CWM. Maybe because original Odys Loox need combination with 'M'(menu)-button to enter recovery mode?? Needless to say PMP5097C doesn't have Menu button. Yet there should be CWM installed, right?

So now when booting, background light goes on, but screen is blank no matter what I do. It does react to on/off switch (background light).

I guess you can see I'm not experienced in this field, but stock ICS ROM sucked big time and I thought I knew what I was doing...

Is there anything I can do to save my tablet?:crying:
[Miscellaneous Android Development] Oma7144:
Use your key together with reset to boot into flash-modus.

- Oma -
[Miscellaneous Android Development] midiboss:
Hmmm. First thank 1000 times for your prompt reply.

All that I've managed to achieve is change with combination of 'VOL+' & 'VOL-' & 'POWER button' & 'reset' pin; Device manager changed to 'Other Devices > Full'. Than I've sucessfully changed driver to rockusb 29 but still RKAndroidTool couldn't see the device.

Am I doing something wrong? I'm really lost here :(
[Miscellaneous Android Development] Oma7144:
Ok, Loox kernel is looking for M.

Tab is booting, so you must have have access via adb.

adb shell

reboot bootloader

- Oma -
[Miscellaneous Android Development] midiboss:
Aha! So my steps should be to download Adt bundle, (somehow) run adb commands you mentioned. That would reboot bootloader into CWM? What steps should I take than if those are correct. I'm really sorry as these must be noob questions to you :)

P.S. Running 'adb shell' returned 'error: device not found'.
[Miscellaneous Android Development] Oma7144:
Here is a small adb pack:

Reboot bootloader will start the tab into flash-modus. Now RKAndroidTool should show "found". Flash again, changing the kernel.

- Oma -
[Miscellaneous Android Development] midiboss:
Excellent! I'm up and running. I hope this is my final question:

As 'adb shell' returned 'error: device not found'. It must be something with driver 'class for rockusb devices > RK29 device' which was manually "forced" by me. Which driver should I use?
[Miscellaneous Android Development] Oma7144:
Manually ... sounds not good. Use this tool: http://crewrktablets.arctablet.com/?wpfb_dl=1187. De-install driver first.

To start adb the tab must be booted.

- Oma -
[Miscellaneous Android Development] midiboss:
Huh. With great help of Oma7144 things came to solution with an extra tweak. When using combination VOL+&VOL-&POWER& PIN-reset my computer found mentioned 'Other Devices > Full' in device manager. After I couldn't use RK29 driver, I, in my deep desperation, tried some other manual driver (Android Composite ADB Interface). After this RKAndroidTool suddenly came to life, allowing me to update. I've changed kernel to 'kernel_308_pmp5097cpro_prestigio', did standard procedure and managed to update. Now I only have to implement screen rotation update fix.

Oma7144, you are THE man!! Also JB seems much, much smoother than stock ICS. Ohhh, one more time; Oma7144, you are THE man!!!:)
[Miscellaneous Android Development] andre_amaral:
there it is..
[Miscellaneous Android Development] Oma7144:
Hm, cam get's loaded. Not really sure what the problem is.

However, you now have a homebrew kernel with additional features:

- Overclocked CPU 1104MHz

- Minimum CPU 24MHz

- Smartass2 governor

- Extended BT Stack

- TUN/TAP Device activated (VPN)

I have a question about the Gemini Joytab 7 (GEM7012-RK). It is based on the RK2918, as far as I understand. I tried a few ROMs, but while they seem to run, the display does not work. It goes gray and then slowly fades out, I guess there is no TFT refresh. I have to say that the display is strange anyway: the panel has a resolution of 1024x600, but the desktop is 852x480, I think, and slightly squashed. Running at native would be much better, but I do not understand why they might have gone for the strange resolution in the first place.

The original ROM is available
