So... one of you with a v5 or whatever (any of the ones that is either currently, or WAS broken with 6.0.1)... I have 2 questions for you.
1) What is the reported capacity of your drive in Windows explorer?
2) Are you able to create a raw image of it with Win32DiskImager (Image Writer)?
Someone bugging the Hekate github apparently has one with 712kb capacity. I told him (assuming gender) to just leave 6.0.0 on it and leave it alone, but then he was told to format to fat16 with a 512b cluster. When all tools tried decided to use fat12, this person was confused about it and asked yet again how to force it to use fat12. Without thinking, I mentioned sdformatter. This appears to have bricked his dongle.
Apparently, using sdformatter actually partitions while formatting, applying an MBR in the process, when these things rely on SFD partitions. I have no idea how to specifically apply an SFD partition, but I do know I've been able to un-brick several sd-dependent devices by reflashing an sd with an image made from a known working one, in the not-so-distant past.
I've already tested my own, and confirm that it will not brick (at least an official v1 or v1.2.... whichever mine is).
I created an image, verified the image against the device, deleted the files off of my dongle, wrote the image back, then launched CFW with it (hekate 6.0.1, ATM 1.4.0 on 15.0.1). My image won't do this guy any good, because mine is the original (or original-ish) and has 2MB capacity. Need an image of one of these 712k jobs (if they exist and his wasn't simply defective).
