[Windows RT Development and Hacking] shivam89:
As I send this reply, I'm trying to use freeandroid4248's drivers with the Windows RT 8.0 WIM Image.

@Velda2222 can you send a pic on what BSOD you got on your Surface?

UPDATE 1: Running freeandroid's driver integration script on the WinRT 8.0 WIM

UPDATE 2: No errors with driver integration, it's commiting now

UPDATE 3: I found some errors and warnings in the DISM log and extracted them here:

I didn't really search what those errors and warnings mean (except for the ACCESS DENIED & NOT FOUND lol)

but I'm still going to try this modified install.wim on my Surface, I have a backup you it won't hurt I hope

Booting from USB got me this https://twitter.com/Subject4S/status/470480441015672832

UPDATE 4:

I used the USB.zip and booted up, I got the Installation I think

UPDATE 5: It reinstalled 8.1, I don't get it now...

UPDATE 6: I think I did [MENTION=903843]Velda2222[/MENTION]'s way of booting to WinRT 8.0 (using unmodified files) and got a BSOD too with some graphical glitches, trying something else now
