[Q] Successful flash having no effect on soft brick

See if you can dig up a 3 part stock firmware to flash (assuming you haven't already, a little vague about exactly what you have flashed, I also presume you're talking about an I9100 ?). Could well be a case of corrupted NAND, this is sometimes the case where you seem to get a successful flash but bootloop won't go away & you're still stuck with only download mode. Fix for that is a motherboard replacement, but I wouldn't be calling it just yet.

If you can't find a 3 part firmware (or if you've already tried one), just get hold of as many stock roms (from Samfirmware/AndroidFirmwares.net/Samsung-Updates.com) as you can & flash away; sometimes these cases are fixed by perseverance (the first 10 flashes don't work, but for whatever strange reason the 11th works, for example).

Search for Hopper8's 'Odin troubleshooting' thread & try all the stuff in that thread, might be something really small/obvious that's causing problems here.

Whoa. You shouldn't be posting here for a Note. I'm asking mods to move your thread. Posting about devices in forums for different devices ain't allowed. Nobody here is going to be able to give you sensible advice because we're not familar with the device.
