Help needed to upgrade xda mini S

[rgp_wizard]

Hi,
I got a xda mini S(unlocked), which is G3 and has IPL 1.x and the firmware versions are
ROM version 1.5.4.2 WWE
Radio Version 01.09.10
Protocol version 4.0.13.20
Ext ROM version 1.5.4.102

Can somebody help me to upgrade the firmware to 2.x.

Thanks in adv,
