Willing to donate to anyone who can help me fix my S7!

Hey XDA. I have a canadian G930W8, exynos flat S7. I had it rooted on stock. MY FRP lock is off. I am selling it so went to flash stock, to unroot and have it fresh for next owner! Upon trying to flash stock Bell mobility firmware i got from the official samfirmware downloader tool, it gets about 30 seconds into recovery and fails. Now my phone cant access anything except download mode. I cant connect to smart switch because it doesnt detect my phone when plugged in while in download mode. I've been using ODIN 3.10, 3.11 and 3.12 Can anyone offer me any help? I am willing to throw a few bucks your way if we can get it up and running. Thanks so much
