Unfortunately, there are bricks thst cannot be recovered using this method, depending on what partitions got screwed up. I'm not sure which got messed up on yours, but there is a chance it messed with something the debrick method cant fix...
In that thread there are debrick.img files posted throughout the last few pages. Try any that are for your device.
I used my 64gb sdcard(class 10) and it worked too
just make sure if you want to reuse the sdcard like normal sdcard, you need to reformat it with your phone instead of your computer, cuz somehow if you format it with your pc it will only show 64mb instead of 64gb lol...
and to my knowledge, sdcard debricking will work with any hard bricked bootloader problem (been there, done that), so it should work for you too unless you did something wrong such as wrong version of debrick.img
