One year ago it stopped working, i didn't know why. In january i connet it and it worked, the i tried to upload the newest firmware from AT&T but suddenly it bricked, well LAN ports don't work but WLAN works perfectly.

The specs are:

CPU: ATHEROS AR2312A-01
FLASH: 29LV800BA-90PFTN
SDRAM: IC42S16400-7T
SWITCH CHIPSET: 88E6060-RCJ

I made a serial cable and got this with hyperterminal:

aaa
bbb
EZ

Then i made a WIGGLER cable, i reemplaced 74HCT244 with a 74HCT374, installed jtag-0.6-cvs-20051228 and there is what i get:
