Onda obook10 factory reset bootloop - Request for system dump

I recently ordered an Onda obook10 dual booting tablet (Android 5.1 +Win10) from GearBest, and received it a week (and a half) ago. It is the V5 version (9th and 10th digits of S/N). Booted into Android at first, swiped around a little, and then left it alone for when I was free. Day before, I booted into Windows, and seeing that an account was already set up, hit the factory reset option (Options: remove all personal files, normal wipe (not thorough)). It rebooted, said it was resetting, then got stuck at 5% for a half hour. I then did a hard reboot, and it starting resetting again. I repeated this a few times, with different waiting periods, but it always got stuck at 5%. I wanted to see what was going on, so I opened the OS selector menu and tried to boot into Android, but that put the device into a bootloop, and it's stayed that way since. I downloaded the recovery WinPE from their website, and tried running it; all went well until the last step (installing the install.wim file), which succeeded, but when the batch file tried to set the boot options/flags, it threw an error about not being able to access D:, and failed. Tried making the recovery USB and installing multiple times, but it failed every time. I then tried Gandalf's WinPE image, which booted, and tried using imagex to install the .wim file to C: manually, as detailed here. This failed too.

I'm at my wits' end, honestly. I have no idea what else to try. There's another WinPE file available for download, but it's dated only a couple of weeks after the one I already have, so I'm hesitant to download it if there's any other option (I have very low bandwidth, it would take me at least two days). Also, it's hosted on Baidu, and the download times out after about an hour, and cannot resume. If anyone could give me any ideas, or point me towards a guide I haven't found yet (I've read all the relevant ones I could find on the Onda forums, but please post them anyway if you think they would be helpful), that would be great.
What would be perfect is if someone could upload, or point me toward a system dump/partition clone of at least the Windows partition and boot partition; I have the tools needed to flash those.

Thanks in advance.
