- Download CrewRKTablets Odys Iron Omni 4.4 V1.3
- Download CrewRKTablets KK Omni V1.3 model fix AOC Q70S15
- Replace the kernel.img in rockdev/Image directory with the kernel.img from a stock n80rk tablet. In order to get this stock image you can start with a stock n80rk, root with TPSparkyRoot, install CWM and backup the kernel.img file using CWM. In case you want to skip this step, Oma has posted the kernel here and the model fix here.
- Copy the model fix from your PC to an sdcard that you can insert into the n80rk.
- Boot the n80rk and turn on USB debugging and make sure the model fix file, and any other for that matter, are on the sdcard and you can see them.
- Power off the n80rk.
- Go to the directory on your PC where you downloaded the Odys Iron Omni 4.4 rom with the replaced kernel and cd to RKDevelopTool_v1.37. This assumes you have the Rockchip Drivers installed, which can be tricky. I am running Windows 7 64 bit and did not have much problem. It is best to look through the ARCTablet forum to see how to install the drivers.
- Start RKAndroidTool.exe, it should start and indicate 7 files to be flashed to the tablet, which are loader, parameter, misc, kernel, boot, recovery and system. backup is not checked. At this point is should show No Found RKAndroid rock usb at the bottom.
- While holding down the Vol+ key on the n80rk, plug a usb cable into the tablet. You should hear the usb bing/bong sound (if you have speakers on your PC of course) and the message on the RKAndroidTool should change to Found.
- Press EraseIDB and the RkAndroidTool should indicate 4096 blocks cleared and there will appear a Done message to the window at the right of the table. It takes about 10 secs.
- Press Run and the flashing will commence. It will take about one minute and again you will see a Done message.
- At this point, the n80rk should reboot by itself and will boot into ClockWork Recovery.
- Move the highlighted bar to wipe cache partition using the Vol+/Vol- keys on the n80rk and press the power key as Enter. From memory, when you hit enter you will need to use Vol+/Vol- to select Yes to cofirm.
- Move the highlighted bar to wipe data/factory reset using the Vol+/Vol- keys on the n80rk and press the power key as Enter. From memory, when you hit enter you will need to use Vol+/Vol- to select Yes to confirm.
- Next you want to apply the patch (model fix AOC Q70S15). This can be done by selecting install zip from sdcard and then on the next menu choose zip from external sdcard and then you will see the file you loaded on your sdcard (model fix AOC Q70S15). You need to select that and then select Yes on the net screen to confirm.
- Once that is complete, you return to the home menu of CWM by selecting +++++ Go Back +++++ and finally selecting reboot system now. CWM popup up two screens when you select reboot system now and I just answered No to both of them, though perhaps Yes is a better answer? Maybe someone can provide guidance??
- I then had to change the rotation by using build.prop (get from AppStore) to modify ro.sf.hwrotation to equal 270 as the screen rotation was incorrect.
- That's it, now you have Android 4.4 running on an Vido n80rk.
