Hello Everyone

I would like to check if anyone on the community could help out on this swamp i've gotten myself into. I own a XPS 10 with windows RT 8.1.  I found a really really cheap keyboard for it (dell dock) and the device won't recognise it. They keyboard "works" in the sense that i can see both batteries in device administrator and if i dock the tablet, it charges through it. So it seems like a software, firmware or driver problem. Or that is what some technician told me when i took it to a store.  ¿Solution? Well, just do a factory reset with the tablet docked in.

So, here is my second problem. When i try to do refresh, reset or whatever I get into this stupid loop and I can't get out of it. If I try to follow any guide (from windows, or booting from usb or going to "bios-like-thing" result is always the same, if I don't insert any recovery device It will ask for it, if I try to do it with the device, it says that some  files are missing, if i create a new device it finishes without a problem but it does not work.

So far I have asked in windows community, but nobody seems to be able to give a reasonable answer. If I check dell's troubleshooting guide or info, It always sends me to Dell supportassist, it works great in computers but this is a freakin ARM device!, can't get any "fixing tool", cant reset, can't use keyboard, bla bla bla.  As additional info whe tablet is up-to-date.

Any answers welcome!

Thanks
