Can someone tell me if I have bricked my Samsung s5?

[Android Central Question]

I know this may be dumb and probably answered like 500 times for noobs like me, but I can't find it on the internet and now I'm pretty scared since I feel like I'm straying from the help people can give about bootloops. I've been trying to fix my bootlooped phone for about a week, I've tried factory reset, data wipe and mount /System, I've reflashed a stock firmware, and have been through 3 batteries, none of these things worked. Ok, I didn't know what do you so I reflashed about 2 other roms until my phone said needed to reflash. I found a compilation of SM - G900T stock firmwares (my model) and flashed that using Odin. Everything was fine until it got to the T-Mobile splash. It turned off and now it won't turn on even if I replace battery, place in fridge to cool down, or hold down power button for 7-10 sec. Anyone know if I bricked my phone?
