Which version of XS++ do I need?
I have v3.1 and it doesn't ask me to upgrade to cid49 or 52.

And you don't need that because there aren't any firmware for W800 CID52

So now if I want to unlock my phone, I need to flash the firmware back to K750i or can I unlock it with w800i firmware?
The firmware is RED36, can I than flash it to K750i RED49 or will I brick my phone?

Read this post and look that links unlocking k750i - Page 3 - Top Sony Forums

I read the post and can do nothing, because everytime a get: "DCU60 flashing only supported for RED CID49 phones!" with setool.
With XS++ I get: "|Binary acknowledge failed with: 15|, |Failed|"

With XS++ you cannot unlock your phone. To apply the patch to your phone(DB2010 CID36), you need to use Far Manager with SEFP plugin.
