Tech ARP posted rev. 2.0 of their Aztech Modem Bad Flash Recovery Guide

This guide was created for Aztech ADSL router modems which are based on the Texas Instruments AR7 chipset. This method had been tested on the Aztech DSL600E and DSL600EU modems. However, it is possible to use this method to reflash modems from other manufacturers, as long as they use the same TI AR7 chipset.
