Sensation (EU) 2.3.23 latest build no boot

Mar 22, 2012
Build with MD5 ebf63dd6682e98589c1bf7fd266d0ae4.
No log, simply no boot. I've done the usual wipes and install via ClockWorkMod Recovery.
Latest firmware from XDA Devs thread, booted 2.3.16 ok, currently back in HTC build of ICS.

edit to be specific: No boot, stuck on the splash screen indefinitely. Though no reboot loop.
