Phone wasn't bricked, it probably just bootlooped. Ive been reading that a lot lately round here with Infamous, though, I havent had any issues with Infamous myself, what version did you install?
What version of TWRP were you using?
What happened when you tried to restore backup the first time? Did it give you an error?
Its weird that it wouldnt let you restore, I dont think it had anything to do with Infamous.
Have you factory reset since this happened? It sounds as if there are still Tmobile stuff leftover from the tar you flashed. Perhaps its in data? Have you tried formatting data?
gromit00 said he fixed it by flashing Wicked rom, you can try that. Funny thing is that I think Wicked rom is made by the same dev as Infamous. They are very similar.
