OUTDATED POST: Follow the first post link for detals.
While there is no recovery image provided with v2.0, i recommend trying out the TWRP (everything touch screen) or CWM 5.0.2.3 ( better confirm menus)
TWRP Recovery:

CWM 5.0.2.0:

Just flash the above in recovery.
Default is 182 DPI ( use 240 for any incompatible apps or check here for market workaround)
