I bought the CUBE iWork8 tablet which came preinstalled with Windows 8.1 Update with Bing CountrySpecific (zh-CN). I couldn't stand the language, so I backuped the drivers with Double Driver, then built a clean WimBoot wim image with the excellent instructions in murphy78's thread "Windows 8.1 Update 1 WimBOOT discussion". I injected all the drivers into the image before the /Optimize-Image /WimBoot phase. All except the "IWD Bus Enumerator" driver failed, but I had seen problems with having more than one "IWD Bus Enumerator" listed in Device Manager before, so I ignored it. Finally I got the image booting on the tablet, everything seems to be working, with no unknown devices listed in Device Manager. The system does not seem to think the device is capable of auto-rotation, however, there is no auto-rotation lock in the Settings menu of the Charms bar. I tried starting the Sensor Monitoring Service, disabling and re-enabling the accelerometer (Kionix KXCJ9) in Device Manager then rebooting, but still they could not get the auto-rotation feature back. Many search results on Google gave me solutions for other devices from other OEMs (Lenovo, Asus, HP, Acer, etc.) which involve reinstalling the latest drivers or settings software from the OEM's support website, which are non-existent for the iWork8. What else can I try to get auto-rotation working? If all else fails, the only way I can think of is restoring to the original image and trying to do an in-place upgrade to a normal version of Windows 8, then capturing the image from there, but it is extremely hard if not impossible to do with only ~6GB of free space left in the C: drive.
