    i have tons of info to post so i figured out it’d be better to make a single thread and enclose all information in it.
    Warning: do not connect external powered hubs/hdds to the keyboard dock, there have been reports of it being damaged by that

    Backing up your system

    1. boot into windows
    2. install macrium reflect (
    3. open reflect
    4. select the eMMc disk
    5. click “image this disk”
    6. choose the destination folder, obviously it will have to be on an external drive
    7. follow the wizard to the end

    please note that no matter what backup software you use, if you restore the entire disk image (specifically, the android partitions) android will NOT boot anymore. This is because Cube (or rather, their ODM) enabled dm-verity so the system detects that it has been “tampered” and  just hangs at boot. to fix that you should reflash the official android image with the files provided by Cube, or use a modified boot.img (see rooting section)

    Entering Bootloader (and recovery) mode

    1. power off the tablet
    2. turn on the tablet, at the OS selection screen select android and OK
    3. as soon as you clicked OK and the screen turns black, press and HOLD volume down
    4. release vol- when you see the recovery popping up

    Entering DNX mode

    1. shut down the tablet
    2. Press and HOLD volume down, volume up and power.
    3. hold until you see the DNX mode message

    if you still can’t access DNX mode, power up the tablet, choose Android and as soon as the screen goes black press and hold vol- AND vol+

    Booting a Linux Mint usb drive

    1. create the drive using the ISO image, use MBR as partition table (if you use Rufus, choose MBR for UEFI)
    2. at boot selection choose WINDOWS
    3. as soon as you chose Windows, spam the ESC key
    4. in the bios, go to the last tab (boot override) and select your usb drive (will be UEFI: yourusbdrive) and press ENTER
    5. when the Mint boot menu pops up, press E (just the e key, not capital)
    6. in the lines that appear, replace the “quiet splash” text with “nomodeset” (no quotes)
    7. you may have to hold down Fn key while typing if you’re using the Cube original dock keyboard
    8. press F10

    Creating a WinPe usb drive

    this one is not directly related to the tablet but it’s a key tool for fiddling with it


    1. download Win8Pe (
    2. alternatively, you can download Win10PE (
    3. get yourself win8 or win10 ISO, you may have to get one specifically compatible with win8pe/win10pe, instructions are included in the respective software
    4. extract the win8pe zip in a root directory of the hard drive (c:, d:, etc)
    5. make sure the folder that you extract it to has a very short name (like win8pe)
    6. extract your windows ISO somewhere you want, again, make sure it has a short path (like d:\win8iso). you can use 7zip for that
    7. launch builderse.exe
    8. click Source, as source directory choose the one you have extracted the ISO content into
    9. click Script, for build model select “normal”, dismiss the error message
    10. for boot manager select “auto”
    11. select “components” from the list to the left
    12. check the following:  directx11, .net framework, internet explorer, ms visual c++, Vss
    13. select Tweaks from the list to the left
    14. UNcheck ImDisk
    15. select Finals from the list to the left
    16. UNcheck “create iso”
    17. click Play button in the top right corner
    18. get a usb drive, 8GB+, format it FAT32
    19. copy all the files in Win8PE\Target\Win8PESE to the root of the usb drive
    20. download BootIce (
    21. launch it
    22. select your USB drive as “destination disk”
    23. click “process MBR” , select Windows NT 5.x/6.x
    24. click install/config
    25. click Windows NT 6.x
    26. click close
    27. click Process PBR
    28. select BOOTMGR and click Install/config
    29. click Parts Manage
    30. select the partition (should be only one) and click Activate
    31. click close
    32. go into the BCD edit tab
    33. select Other BCD file
    34. open E:\Boot\BCD (where E: is the letter of your usb drive)
    35. click Easy mode
    36. select “partition” radio button
    37. select your usb drive as “disk”
    38. select the partiton as “partition”
    39. check the Test Mode box down below
    40. click save current system
    41. close
    42. repeat step 33-41 for the file H:\efi\microsoft\boot\BCD
    43. you can now boot your usb drive as a winpe environment

    General guidelines to install your own windows and mantain proper dual boot


    • back up your entire drive
    • do a backup of the windows drivers using double driver, just in case
    • go into c:\windows\inf and backup
    • using a bootable drive (linux or winpe) delete all the windows partitions, they are the last 4 (system 100MB, microsoft special stuff 16MB, windows ~41GB, recovery ~1GB)
    • install your windows
    • using a bootable drive, resize your new windows partition down to something like 30GB, then back it up (only the C:)
    • delete all the new partitions that were created by the installation
    • take out the first image you did of the whole disk, restore partition 1,2,3 and the 4 original microsoft partition SAVE for the windows one (meaning you restore system, specialstuff, recovery)
    • now restore your newly installed windows image into the blank space between specialstuff and recovery partitions
    • resize the windows partition to fit
    • now you must adjust the BCD files in the system partition to point to the new windows partition. i suggest doing that using bootice from a winpe usb drive. note that in order to see the system partition you must use diskpart to assign a drive letter to it
    • when done, boot windows, install the drivers you backed up (or download them, cause double driver makes some mistakes)
    • put the into windows\inf
    • take out your first image backup of the disk, and copy the contents of c:\recovery to the c:\recovery of your new windows partition
    • done

    How to mount the SYSTEM windows partition


    1. open an administrator command prompt
    2. enter “diskpart” (without quotes)
    3. enter “list disk”
    4. look at which number is your emmc drive
    5. enter “select disk #” where # is the number of your drive
    6. enter “list partition”
    7. enter “select partition #” where # is the number of the SYSTEM partition (should be 12)
    8. enter “assign”
    9. now the system partition is visible and accessible


    Fixing Bosch Accelerometer issues (windows)

    if you get the yellow triangle on bosch accelerometer or if you get the message “external backing provider not recognized” when trying to reinstall the driver, do this

    1. go into device manager
    2. right click bosch accelerometer under sensors
    3. click uninstall
    4. go into C:\Windows\System32\DriverStore\FileRepository there should be a directory named something like boschaccelerometer.inf_amd64_4158f2c511c66197
    5. delete that
    6. alternatively, open explorer and do a search for bosch* and delete all the files it finds
    7. reboot

    now you can reinstall the driver (manually) from device manager and it should work right off the bat


    Flashing the tablet with stock Cube i15-TD images



    Flashing a modified boot image (android)


    before rooting, or if you restored a  backup image and android doesn’t boot anymore, you must flash a modified boot.img that disables some security checks. Be advised that by doing this you not only expose your system to more vulnerabilities but MOST LIKELY you will cut yourself off of firmware OTAs. i therefore STRONGLY DISCOURAGE doing this (and/or rooting) unless your model is i15-T or i15-TD because those have official images, while i15-TL DOES NOT.


    1. boot tablet in fastboot mode (see other section)
    2. connect the micro usb 2.0 port to your PC
    3. install the intel phone flash tools, or alternatively
    4. open an elevated command prompt
    5. type “fastboot device” (without quotes)
    6. you should see your device listed
    7. type “fastboot oem unlock”
    8. type “fastboot flash boot yourbootimage.img” (where yourbootimage.img is the appropriate file .img for your model, see the downloads)
    9. if it fails to flash you have issues with one of the first 3 partitions, most likely because you reinstalled windows on your own. you must restore the original 3 partitions.
    10. using the vol and power keys select normal boot



    1. flash a modified boot image (see appropriate section)
    2. download and unzip the iwork10root stuff
    3. open an elevated command prompt (administrator)
    4. navigate to the unzipped folder of the root stuff
    5. turn on the tablet and boot to android
    6. make sure USB debug is ENABLED, if not, enable it (google how, its really easy)
    7. connect the micro usb 2.0 port to your pc
    8. type “root.bat” in your command prompt
    9. wait for it to hang on adb shell su –daemon
    10. disconnect tablet, reboot it
    11. supersu will want to update su binary, let it do so. it will fail, close it then.
    12. reconnect the tablet, type “root.bat” again
    13. should be rooted successfully.


    Making your own modified boot.img

    this is more of a guidance for power users rather than a foolproof guide, the procedure is quite long and has possible complications that you must be able to figure out on your own so i strongly advice you don’t try unless you know what you’re doing.

    1. somehow, get the boot.img file or dump it from the tablet (dd) it’s the 3rd partition (30MB)
    2. download android bootimg tools (wget
    3. extract using tar xvzf android_bootimg_tools.tar.gz
    4. launch ./unpackbootimg -i -o
    5. extract the ramdisk: gunzip -c boot.img-ramdisk.gz | cpio -i
    6. mind that those 2 commands put all the files in the current directory, don’t mix things up, move your files to appropriate directories after each extraction
    7. go to the ramdisk directory, open default.prop and change the value from 1 to 0 (also make sure that ro.debuggable is set to 1), close and save
    8. open init.rc , change user from media to root under the service media section, close and save
    9. repack the ramdisk: find . | cpio -o -H newc | gzip > ../newramdisk.cpio.gz
    10. open the -cmdline file, copy content to clipboard
    11. run: mkbootimg –cmdline ‘pasteyourclipboardhere’ –kernel your-kernel-file –ramdisk newramdisk.cpio.gz -o mynewimage.img
    12. done



    • I15-TL 4-11-2016 6-46-35 is the driver package from i15-TL. it’s fixed by hand cause driver double didnt backup everything correctly. it also cointains
    • is the package for rooting. note that you need the appropriate modified boot.img too
    • rootbootT.img is the modified boot.img for i15-T(D) kernel version 3.14.37 built on mar 2 18:22:46 CST 2016
    • rootbootTL.img is the modified boot.img for i15-TL kernel version 3.14.37 built on mar 16 09:47:51 CST 2016

    that’s all for now, have fun

    Wow cool, thanks. Does this mean a pure Android is possible?

    Beam me up Scotty

    Wow cool, thanks. Does this mean a pure Android is possible?

    yeah i guess so. probably have to delete win partitions, resize android userdata and flash modified bootimage to bypass dm-verity

    done, phew it was a lot of work. @Chris can you please make this sticky?

    Tanks for this topic.

    I have a Cube iworks 10 flagship dual os (i15-tl)
    Just to Be sure…do you have the link to the official images for Windows and android….i saw them on the cube site but i cant read Chinese and the translater doesnt translate the images that explain How to do It.
    Could you explain ?
    There is nothing wrong but i want to know if It does go wrong.

    Hope you can help


    • Posts: 296

    the link on the cube site is for a zip that contains a link for a baidu share that no longer exists. i believe somebody around here made a mirror of that, but can’t remember which post had it inside

    as for the guide to restore the system from the images, look at my other thread for tips about restoring, its linked there

    Does reflashing the android partition requires me to also reflash windows? Or is there a workaround for that?

    I plan to root mine, but I’m afraid if it get’s an update I’ll have to reflash the whole tablet to update it, I wouldn’t mind reflashing just the android partition because I mostly use windows.

    • Posts: 296

    can’t know for sure but there is a very high chance that in order to get the OTA you’ll have to re-flash using the intel phone tool which erases the whole disk including the windows partitions.

    let’s say that atleast you can backup the windows partitions and restore them after, that you can do

    • Posts: 9

    yeah that’s a good idea


    Edit: tried to flash the modified boot image and got an error! Even though the last thing I did is flash the official images!!


    Do I need to restore the partitions? And which ones are they? I have “bootloader2” and “bootloader” -100mb each-, and “boot” which is 30mb. Are those the ones I need to restore?

    Edit 2:
    Nevermind, just restored them and rooted successfully.

    Now that’s a good bit of useful info, appreciate the effort!

    Will have to see about trying out the root sometime soon.

    So… in order to get a working custom boot image, you unpack it, make the changes to default.prop and init.rc and repack right?

    Hi Laura,

    thanks for all the really great info.

    I’ve just a question regarding “General guidelines to install your own windows and mantain proper dual boot” – what happens if you just install Windows and don’t do the messing around restoring original partitions and so on? What parts of the dual boot system don’t work properly without this?
