Installing OpenWrt
List of commands to be issued before flashing using the FTP method as directed in OpenWrtDocs/InstallingAR7
create mtd5 spanning mtd1-mtd0 (quote SETENV mtd5,0x90010000,0x903e0000).
set the MAC_PORT variable to 0 (quote SETENV MAC_PORT,0).
- flash to mtd5 instead of mtd4
Restoring Qwest Firmware
First obtain and extract http://www.qwest.com/internethelp/modems/gt701/docs/gt701_wg_qw04_3_60_2_0_6_3_recovery.zip. The files you need are in the "gt701-wg qw04-3.60.2.0.6.3_recovery/image" directory.
During the ADAM2 access window (approx 2-7 seconds after power up) connect to 192.168.0.1 with a console-based FTP client. The following assumes you're in the previously specified directory. Both the username and password are "adam2".
