Walkthorugh to dualboot K9C3

WARNING: by flashing new bios you will probably loose camera (let’s hope that only temporary, until new bios update). I haven’t checked whether the camera was working in windows after bios update, but after android flash and windows recovery it doesn’t work in neither android or windows

Needed files:

bios 1.05 for K9C3 https://drive.google.com/file/d/0ByUOEKnPRz9geGJpMGtLZG1VdEk/view?usp=sharing

intel flash tools https://drive.google.com/file/d/0ByUOEKnPRz9gdFhrUDYtYlN4bVE/view

K9C6 android rom https://drive.google.com/file/d/0ByUOEKnPRz9geTNIcDRPOFBzdVE/view?usp=sharing

windows 10 recovery for K9C6

first backup your data from windows, since android instalation will wipe the original windows and everything will be deleted

charge the tablet to full battery

then you need to update bios preferably from the root of C: drive to avoid problems (also run the installer as admin), as described in this video from Chris

Now you will have dualboot menu after restart, but don’t try to load android, you will just get windows bsod

install intel flash tools on your pc (not on the tablet) in this order

iSocUSB Driver

IntelAndroidDriver

PhoneFlashTool

boot your tablet in fastboot mode, hold both volume buttons and press power button for 3 seconds, you will see “DNX FASTBOOT” on the display

Connect the tablet to your pc using usb cable

launch intel phone flash tool, you should see the tablet in the device listing

In phone flash tool browse for flash.json file in folder with extracted android rom image

select blank configuration and flash the rom to tablet (see first pic)

After reboot you should have working android, first android boot takes some time, it will hang at the intel inside logo for a few minutes, so be patient

few tips for first steps in android:

1) change language from chinese to your preferred language: settings icon (bottom left), globe icon, first line

2) delete data and cache of TOS launcher app in all apps settings, this will reset the names of applications to english

3) launch TeclastAutoUpdate app and download and install new android update, otherwise the store will not work (this app crashed in the first try, but then it worked)

4) you can uninstall unneeded chinese apps and install some better launcher from the store

Now we will restore windows and make the tablet dualboot

You will need at least 8GB flash drive, formatted to fat32 and during formating set the label to “WINPE”, otherwise it will not work

Copy all the files from win10 recovery to flash drive

Connect the flash drive to the tablet and reboot, the tablet will detect it automatically and you will be able to choose windows from dualboot menu

The whole windows installation process is automatic and it will not request any input from you, it will take some time, so make sure that the tablet is charged

after the windows installation you will go through standard windows OOBE where you can setup user etc.. and then, after few restarts you will have almost fully working dualboot K9C3

What doesn’t work: camera doesn’t work in android and even in windows, it is probably bios issue and I suppose it will be fixed in the next release

The emmc is partitioned that you have 20GB storage for android and 33GB for windows (with cca 20GB free space). The rest of the flash is used for android system and windows recovery (see second pic)

The android experience is pretty smooth, system memory usage after boot is cca 1GB, so there are 3GB free which should be more than enough for anything, android is 64bit

Superuser app is not yet working but rooting the android shouldn’t be hard, since you can boot any linux from usb stick and mount any of the android partition for read/write access, I hope that I will succeed with this today, maybe someone who has some experience with this can help
