Mirek190 over on the XDA forums has released an updated new custom ROM for all Teclast X98 Air 3G and Air II variants. This is without a doubt the best ROM yet, even if it’s back on Android 4.4.4. Mirek190 might have gone back to Android 4 as the Android 5 ROM was based on a beta Android 5 Lollipop release from Teclast.

Make sure you download the version that matches your X98 Air 3G or Air II model number C5J6 etc (See the back of your Air II or air 3G) You can flash it via the Intel MFG Tool or via desktop using ADB. If you want to reparation Android and Windows there are partition files included. Or the alternative you can just flash the system image using the supplied XML files within the download file. Remember only do flash if you understand the risks of losing your Windows image, data and apps. Make sure you back up everything.
Bios v2.02 is required. Again, there is a risk updating the bios. TT is not responsible for any bricked X98’s. A full wipe is recommended after flashing.
