They have added this

Firmware Version: BZ.qca956x.v3.4.7.3284.150911.1650
RSA Signed Firmware. Verfiying please wait...

Decrypted hash: f8 2b 45 72 9f e4 5f 46 a0 96 43 37 57 4f 49 ab 43 dc 1e 8c
Image hash    : f8 2b 45 72 9f e4 5f 46 a0 96 43 37 57 4f 49 ab 43 dc 1e 8c


RSA signature check.
Could it be similar to this?

They must have some sort of protection in there bootloader,
immediately after OpenWRT is put onto the device via TFTP the error
"Application terminated, rc=0xFFFFFFFF" shows up.
I wonder what it's expecting?

Interestingly enough, there is a 2nd kernel partition ( kernel0 and
kernel1 ) It boots into kernel1 if kernel0 fails.
