I have the same bricked esr600.
I tryed to flash ".dlf" via serial U-boot. Nothing helps.
After that i found topic about "header.x86" and "dd" and folow instruction to create uImageESR600.
I've decoded original firmware ESR600-V1-4-5-55.dlf with header.x86 and stripped first 192 bytes with dd.

Result:
Code:
 binwalk uImageESR600
DECIMAL      HEX          DESCRIPTION
-------------------------------------------------------------------------------------------------------
0            0x0          uImage header, header size: 64 bytes, header CRC: 0xC188B2BE, created: Fri Jul 24 12:34:17 2015, image size: 1873102 bytes, Data Address: 0x80000000, Entry Point: 0x8000C110, data CRC: 0xE2B2814F, OS: Linux, CPU: MIPS, image type: OS Kernel Image, compression type: lzma, image name: "Linux Kernel Image"

I cannot load this image file to the router... it keeps giving me bad magic number errors when I try to boot afterward.
