You may have, when trying to charge without a Neo FR that's booting correctly. 
Doing so DIScharges battery!!!

check the -a parameter of dfu util cmd line. It has to match your actual file 
you're trying to flash.
Also make sure you got the right file, i.e don't mix with *.tar.gz, those are 
not for dfu!

As mentioned above, this is with correctly booting FR.
DON'T DO THIS when you messed up your FR boot! It will drain your bat.
Fix boot first, then recharge battery.
Charging bat for 12h is a recommendation, not mandatory. Not draining bat to 
death IS mandatory.

where in the phone?  
There's NOR u-boot, which will allow to flash a new NAND u-boot + rootfs 
("boot image") any time. You shouldn't be able to break NOR u-boot.
