[Q] Difficulty getting Android to boot on X1

---

Alright, before I get any complaints, I'm not reading through 33 pages of "How to install Android" to see if anyone has this problem as well. It's a simple question I have, so your patience in possibly reading it again is appreciated.

*steps off soapbox*

I have an Xperia X1a. I have Windows 6.1 currently running on it. I've downloaded a current Android 2.2 install from the late Myxperoid, unzipped it to the root of my Micro-sd card, ran Haret.exe, got a bunch of code, the phone rebooted... and it booted Windows immediately. I've tried four different android installs, following all instructions, and this still happens. No Android, just Windows every time.

Why?

I think that Windows Mobile 6.5 Rom works with me is it applied to the 2.2 of the typical mistakes with android

which windows version doesn't really matter
use this version of android http://forum.xda-developers.com/showthread.php?t=709632
but not the latest version, as it has some stability issues, so you should use the previous version!
also format your sd card before you put the files on it
