The issue with ROM Manager is that, the phone is a T989D, from Canada, And i also have an S3, with the S3 its also the Canadian version (i747M) i found that because its not the american AT&T Varient (i747), it wont show up in ROM manager when i press on "Flash ClockworkMod the phone wont show up in the list. Also my T989D dosnt have ClockworkMod installed already, it has a basic Android recovery on it. The T989D right now is on ICS, and i want to flash the CyanogenMod 10 on it, thats why i need the ClockworkMod. Any suggestios?
try this
i followed that guide for my D and it worked no problem... and if it comes down to it, there are flashable zips for TWRP in its thread. you can odin that CWM, flash cm10... then use rom manager (which will work for you) to install cwm6. i'm running it just like that... only difference is that i went to cwm5 when i was on GB.
I was unaware that Samsung did the canadian variant again with the 3.... i'll possibly be getting one soon.... ugh...
