I have a rooted T-mobile Sensation 4G and the downloaded rom is labeled su-2.3.6.3-gfgh.zip. My question is will the OTA of ICS install without issue b/c I have a system that keeps asking me to install from HTC and it is 14.24 MB (no other info available) and it fails everytime....triangle with ! and droid...hangs untill remove battery then boot normally. Could that system update be the ICS? and or why wont it install...any ideas?
