Default (REQUEST) ROOT HTC DESIRE with baseband 1.10.34D.17_20.26.30.27U

I got OTA update for my Desire V, it from ASIA(Vietnam), for specific details in this update:

baseband version: 1.10.34D.17_20.26.30.27U
build number: 1.73.727.1

My phone quite slow performance, thus I want to ROOT my phone. But all the tutorial not for my baseband.
How the way can I ROOT my phone?
Please reply my question. Thank you so much for supporting.
