Please note there have been a few comments about freezing. lag and camera issues by some XDA users, only older X98 models.. It seems it’s most stable on the X98 Air 3G C5j6 and HG9M Air II 64GB models at the moment. You  can flash it via the included bat file or via Intel MFG tools. There is an optionto flash just the rom leaving Windows untouched. And like always, please flash this with care. Tech Tablets, isn’t responsible lost data, bricked or burnt  Teclast X98’s!

  1. Chris, love the site and the videos BTW but enough sucking up ….

    Q1: Is the Android setup such that its a single partition (for apps etc) or is System and Apps on different ones?

    Q: Is it possible to adjust the partition sizes for Windows or Android (using a tool from Windows like Partition Magic or even a Gparted Live CD? I’m not sure what the spacing is but somehow I doubt it will be what I would want…

    • Hi, Android using a whole bunch of partitions. About 6-8 of them. Justing them just isn’t an option as I have always run into issues with tablets not booting or boot loops. With the dual boot you can delete Android and later increase the partitions for Windows using a partition manager. We have info on that here: http://techtablets.com/forums/topic/how-to-delete-android-and-merge-partitions-in-windows-for-more-space/

      • Thanks. But within Android, does it see it as one partition for data and apps or two? With phones some Lollipop ones have single partition which means no problems with running out of the right type of storage partition for installing more apps

  2. Sorry for probably easy question but I need to ask after installing this rom: what is the way now to install windows 10 as a second boot?

  3. Sir donyou observed android system tabs which were already closed, recent tabs in mirek 5.0 4.1, I observed earlier also but in lollipop only.

  4. Could you tell this software operating method for beginner ????

    • There is a flash.bat inside the folder. Run that and follow the steps.

  5. Will this or the 5.0 official room work on the 32GB variety of the Air II?

    • This rom will, but some have reported minor issues like inverted cameras and lag on first boot.

    • It works perfect. Ony issue i can see that you cant move your apps to an sd card. I cant manage to get this working with link2sd and an proper sd card with the right 2 partitions.
