Sure fire fix assuming hardware is ok and uboot intact is uboot based recovery, interrupt the boot process and set your computers IP to a static IP of 192.168.1.100. Start a TFTP server on your computer serving antMiner_S320141013.bin and run the following commands on your miner.
tftpboot 0x80000000 antMiner_S320141013.bin
erase 0x9f020000 +0x7c0000
cp.b 0x80000000 0x9f020000 0x7c0000
bootm 0x9f020000
Just put the firmware bin file into the root directory on a tftp server running on 192.168.1.100 subnet mask 255.255.255.0 and execute the above commands from uboot to flash it.
Thanks for the output, I'll browse through and see if I can spot a light at the end of the tunnell.
By the way, I meant the command altogether, i.e:
run mtd -r erase rootfs_data
This won't work from uboot so don't bother trying it if thats as far as you can get.
