So, Oma makes ROM's for the V88 tablet, but with the proper kernel changes, they work on the X3. Unfortunately, there are some limitations as they were not originally designed for the X3.

If you are the adventurous type and want to fool around with the ROM's here are the links to download and try.

OmniROM v1.4.1 (KitKat 4.4.0):
(Download link: )

CM11 v1.2 (KitKat 4.4.4):
(Download link: )

AOSP v1.2 Alpha (Lollipop 5.0):
(Download link: )


Here are the detailed directions. These directions assume you have previously done a firmware upgrade, i.e. the drivers have been setup properly in Windows (and you get the green icon in the RK Batch Tool):

  1. Download the Gen-1 loader ( ). All the official ROM's use the Gen-2 loader, while the Oma ROM's require the Gen-1.
  2. Extract the ZIP from step 1 to its own folder. Run the file RKDevelopTool.exe.
  3. Under the text "Boot", to the right, click the "..." button and locate the "RK3188Loader(L)_V1.24.bin" file. The "Ver" text box should say "1.24".
  4. While holding the VOL UP button, connect the USB to the device. The text at the bottom should change from "No Found any Devices" to "Found One LOADER Device". If you get this text, continue to step 5. If you dont get this, perhaps you installed the driver wrong?
  5. While holding the VOLUME UP physical button, click "Erase ID Block". You should see success, and the device will reboot. (If you don't hold the VOL UP button, the device will reboot normally, which you don't want - you want to be in the loader mode. If you reboot normally, just force power-off the device by holding the POWER button, the do the previous direction of holding VOLUME UP and plugging in the USB). Text at the bottom of the window should return to "Found One LOADER Device"
  6. While holding the VOLUME UP button click "Erase All Blocks". Again the device should reboot. Again wait for the text to show "Found One LOADER Device".
  7. While holding the VOLUME UP click "Download". You should see some messages saying that it wrote the file. Device might reboot again.
  8. Extract the ZIP for the ROM you want to its own separate folder (they all have the same file structure and development tools, so it is important to extract them to their own folders)
  9. Download the iFive X3 kernel: here:
  10. Extract the kernel.img from the iFive X3 kernel 7z file and copy it to the

    ROMFOLDER\ rockdev\Image

    subdirectory for the ROM you extracted. Overwrite/Replace the kernel.img file that exists in that directory.

  11. Under the \RKDevelopTool_v1.37 folder run RKAndroidTool.exe as administrator (right click "Run as administrator"). If the device is properly in loader mode, the text at the bottom should say "Found RKAndroid Loader Rock Usb". If you see the text "No Found RKAndroid rock usb", then unplug the USB, power off the device (by holding the power button for several seconds), then hold the VOLUME UP button and plug in the USB again.
  12. While holding the VOLUME UP button, uncheck the box next to #1/Loader and click "EraseIDB". You should get an alert window saying IDB was erased. Click OK and the device will reboot. Confirm the text at the bottom says "Found RKAndroid Loader Rock Usb" after reboot. Close RKAndroidTool.
  13. Open RKAndroidTool.exe again as administrator. Confirm the text at the bottom says "Found RKAndroid Loader Rock Usb". Otherwise, unplug the USB, power off the device, hold the VOLUME UP button and plug in the USB. Release hold of the VOLUME UP button, it is not needed for the next step as you will want the normal reboot.
  14. Assuming you have successfully replaced the kernel.img file, click "Run". Keep an eye on the status messages - you should see it writing and then checking the image file it is uploading (it will go from 0K to 800000K or so), let it reboot normally. It will boot into ClockWorkMod (from here, use the volume rocker to navigate and the power button to advance)
  15. Do "Wipe Data/Factory Reset".
  16. Then do "Reboot System Now". If you get any prompts (like fixing SU) just click NO. Even if you click no, it will reboot normally.
  17. The system will reboot to a loading screen that has red text saying "Crew RKTablets". Wait 3-5 minutes and you will eventually be brought to the main Android system :).

These are the issues I have had so far:

Lollipop only (current 1.2 alpha build):

  • Audio does not work.
  • Youtube does not work.
  • Video does not work in browsers.
  • USB storage (on PC) does not work.
  • Camera does not work (Camera has not been coded yet)

KitKat only:

  • Camera works, but the image is 90 degrees rotated improperly (e.g. if you do front-face camera you should be looking at an image of yourself upright, instead the image is sideways)

All ROM's, KitKat and Lollipop:

  • Screen rotation does not work (I think this is a problem respective to the X3). You can get apps to manually switch the orientation between landscape and portrait, but the automatic sensor doesn't seem to work.
  • SDCard seen as 13.89GB instead of 28+ GB
  • Bluetooth does not work
  • I don't believe the screen is set to 1920x1200. The nav bar looks bigger than the official ROM, with no way to make it smaller?
