1st - Format class 10 card to Exfat file system or structure
2nd - Using Win32Diskmapper, just point to the file (in my case kk900tunbrick image) and write to card. *Nothing special, should I verify Md5 sum, or just leave it as default settings?
3rd, Proceed to attempt to Unbrick (Battery at 100%, Put Sd card in slot, Then Add Battery, Connect cable - some say, some say doesn't matter, to computer, then attempt to boot with button sequence to download mode, or may boot by itself?)
Also, if the 1st image I downloaded does not work, can I reformat or wipe the sd card and start again with the other file (I believe a Pit file??)
