A new port of Ubuntu Touch just has arrived for RK2918 based tablets.

The first version of the RK29 port is released on CrewRkTablets (crewrktablets.arctablet.com) now.

Custom kernels are currently available for following devices:
* Odys LooxPlus
* Odys Loox
* Odys Next
* Odys Xpress

I would like to encourage you to install it on your RK29 tablet and let me know your experiences and opinion about the system.
* Pros / Cons compared to Android
* UI Usability
* Performance
* etc.

Be aware, it's on your own risk.

Update availabe (V0.1.2):
Changes:
* Corrected initial boot behaviour after RkDevelopTool (automatic boot into CWM)

The installation guide (Installation_Guide_RK29.pdf) is contained the package (CrewRkTablets_RK29_UbuntuTouchPreview_V0.1.0).
Please read ist carefully before starting the installation.


Please request for new custom kernels ONLY if you are willing to provide me with a hardware sample of the intended target device.
(Doing kernels remotely without a sample device available is just too ineffective ) Thx


Thx for your inputs

Wait a minute.
What did you flash?
1. you need special kernel for ubuntu touch, a normal Android kernel, eg stock rom kernel, does not work.
2. you need a working kernel from the above list for your tablet, and if it is not a Odys Loox Plus, you have to change this, as mentionend in the manual.
3. if your tablet meets not the points 1 and two, we could look if we can compile a custom one, but sources would be needed.

HI magio081,
Thanks for your post. It really helps if a reply contains details as yours does.
This sounds very likely as your device tries to boot into the system rather than into the CWM-recovery right after the RKDevelopTool programming.
Please try to boot it into CWM manually by pressing M-Button at startup without power supply being connected.
If the device comes up in CWM you can continue the installation as described in the installation guide.

For all the others: Please post some details: what steps have been done, what did you see up to this point and what do you see currently. (A blank screen with background light on may identify a different cause than just a black screen). I'm glad to help you through the installation, but I will need to read some details on your situation. Thx

Testing through all kernels is a rather dangerous sequence.
Do you know what listed device your tabelt is compatible with?
Did you go through all the installation steps listed in the installation guide? (the pdf document which is part of the package)
Please could you describe in detail, what your device did/does show on the screen at each step of the installation?

OK. I think im missing here something huge. Lets start from very start:


About tablet
model number: TR720F
Kernel: dong@dong #735
Firmware: 720F_RT5621_GT811&818_RTL8188_AT28_GC0307_MT9D112_ CAT6611_TP01_OTG
Build no.: RK2918_ANDROID4.0.3-SDK_V2.10_20120205


Stock rom was 2.3 i upgraded on 4.0.3 with some RKBatchTool what i found for some simular Titan tablet. On that rom tool i have only one file to select - update.img. And all work perfect (ex. camera).

how i tryed to install ubuntu touch

1. copy raring-preinstalled-phablet-armhf.zip & CrewRKTablets_AOSP_4.2.2_Format_NAND_Fix.zip to sd

2. copy kernel.img (kernel_308_odys_loox_plus_ubuntu_201306091043_Ubu ntuTouch_V1) to rockdev/kernel.img

2a. check all 7 programming parts

3. turn off tablet, hold M button and connect to cable (status: found RKAndroid loader rock usb)

4. eraseIDB (status: erasing IDB OK)

5. Run (status: size 471059, written & checked, download file ok, elapsed (144110MS))

6. Tablet start blue odys screen and freeze on that.

Knowing that the cheesecake is compatible with the Loox, you are correct to use the Loox kernel.
Please could you also post what parts of the installation you have finished, and waht your device dis/does show on the screen.

@all who have similar problems:
Please try to post as many details as possible on your proiblem: What steps have been performed? what did you see on the display? etc.
Please also try to access the device via USB and try to do a 'adb logcat' and 'adb shell dmesg' from shell or windows command line.
If you can post any of these outputs, this helps for problem analysis.
