Rooting without Revolutionary

Hi,
I want to increase my internal memory by using Link2SD, for which I need my phone rooted. I have spent 2 days already trying to figure this out, but I have made zero progress. I have tried everything I could google, but most guides refer to revolutionary.io website, which is down.

I found this guide - http://forum.xda-developers.com/show....php?t=1600904
Even though it's for Incredible, I though the steps would be similar, perhaps with different files. Anyway, I'm stuck on step one where I need to unlock bootloader using HTCdev.

fastboot oem get_identifier_token returns command error:

Quote:

(bootloader) [ERR] Command error !!! OKAY [ 0.010s] finished. total time: 0.010s

I am sure I have all my drivers installed correctly, both adb and fastboot work just fine (both show device when connected).

From what I understand, it is because of my HBOOT version, right? I tried running different RUUs I could find, but it always ends up with an error - either model id error [130], or something saying my image is newer than the one I want to upload (maybe it's bootloader version error [140], I don't remember now).

How should I proceed now?

Thanks
