Win8.1 restore image
Have you managed to come right with the image yet??? In one of the previous posts someone did upload an image of the recovery (Sloogle_Flugelmann if I got that correct). You also mentioned you found an ISO for an Android install for this unit! Could you please supply the link for this? I would love to get rid of the Winblows on it and use Android......... although I do still need to get a replacement for the OTG hub that I was using as this never seemed to work like it was meant to in the first place I think (That and the fact that in my attempts to get Winblows off of and Android on the tablet the micro USB port used for power broke off the board of the unit, and I just couldn't be bothered to fix it).
I'm actually really surprised that no one has yet mastered this, taking into account this unit has been out for almost 2 years now (Mine, just gathering dust, because it's original purpose was to be wiped and XBMC/KODI installed onto it, Velcro'd to the back to the TV, and forgotten about (HDMI Output to TV and USB used for the Remote Control and Power to the unit), but that just seems like a pipe dream at this juncture). The specs of the tablet would be absolutely ideal for this except for the space required for the library (As currently, the home partition of my normal box is full from the data that gets stored there for all the series and movies, and this has been made bigger not so long ago to 40GB, although I think by using the memory card I can redirect the library to store there instead of on the internal...... Hopefully). Although none of this is possible without getting XBMC/KODI onto it
Anyway, if anyone has any thoughts, I would appreciate it very much.
Thanks.

I own the native android and windows 8.1 versions of this hardware.
Key differences between the two:
The cheaper android version has 64bit UEFI firmware, with lots of scary options that can soft-brick the tablet. (I know, I have softbricked my android one) The options I know do this are disabling the xhci mode (it kills OTG!!) and messing with the display config (No display, even on HDMI out).
The windows version has 32bit UEFI with significantly less options, and as far as I can tell, you cannot softbrick it just by toggling an option in there like you can on the android version.
Android version's UEFI supports boot from SDCARD!! Windows version UEFI does NOT.
(GRUB does not know how to deal with booting from the SDCARD though, and drops to GRUB prompt)
(Windows 8 64bit installer bombs with inscruitable "ACPI bios error")
Android version's firmware has option to present the MMC slot as choice of ACPI bus child, or PCI bus child. GRUB can see the device in PCI mode, but booted kernels hang.
The windows version is very picky about the USB sticks it will boot from. I have had the best luck with a pair of sandisk 8gb sticks. The compact HP ones I have dont show up in the UEFI menu, even though they are prepared properly.
The recovery image for the windows version is available from Nextbook, Kinda Sorta. They point you to a 4.4gb ISO file hosted on Mega. Mega throttles the **** out of the download making most attempts to get such a large file fail. I had to use an aggressive download manager (flashget) to get the file, and Mega reset the download over 70 times. I would NEVER have gotten the file without the downloader. I needed it after trying to play around with other OSes on the tablet. It works. I used Rufus to make it into a bootable USB stick.
In a nutshell, the recovery image boots into WinPE, then wipes the whole internal flash, builds the partitions, then populates them. It copies the INSTALL.WIM file to the recovery partition, because it is a two-stage process, and the script looks for the image there. If an enterprising fellow decided to do so, they could probably modify the scripts (and the WIM files that contain them) to look for the WIM from USB, and force it to make a much smaller recovery partition. I am actually considering that modification, as well as enabling NTFS compression from the start.
Takeaway:
Of the two, the cheaper (78$ vs 99$) android offering appears to have the more capable firmware, but it is very easy to softbrick! It is unable to start the windows installer though. I very much doubt that a raw dump of the android version's flash will boot on the windows version, as it uses a 64 bit loader. Testing with a 32bit loader seems like an amusing thing to try though.
I would have to buy ANOTHER android version tablet to dump the flash, since the one I have is now soft-bricked.
I was mostly replying to point out that the windows version's recovery image can be grabbed from Nextbook's site.
What I would personally try first, is dumping a working win8 flash to an SDCARD, and trying to boot android version hardware on it.
