4 future reference, just an fyi, ...........a known bug w/ ACSrecovery1.0.0.5CWM4: when flashing a ROM, you do not have to wipe cachex3/wipedalvikx3, instead you select 'pre-install wipe' , select 'yes' + then you flash your ROM..........it's been reported by some users on the acs forums if you click 'yes' then change to 'no' you will still get a pre-install wipe...............(you would then go back to recovery + select your last backup, so no worries as backups are solid w/ this recovery.)
.............come to think of it, if you load ACS recovery first, run a backup, prior to going thru w/ odin EI22 install here, then you have the option of returning completely to your prior setup via ACSrecovery in case you change your mind (i have done this w/ other ROMs, using ACS recovery, not yet w/ EI22) ............other than why you'd want to go back to that last setup, any thoughts Paul?
