Linksys Disaster Recovery

Theres nothing like learning the hard way! As a result of my usual "If it ain't broke, it hasn't been fixed enough" approach to life, I fiddled with the Linksys until it innevitably went into a coma/ vegetative state. How did I manage this you ask? Simple, I started by doing a firmware upgrade using the wrong sveasoft image, which resulted in a moderately upset linksys which refused to talk to me on the web interface. With the help of our trusted Android (Andrew), I managed to do a reset-hold/ ping / tftp recovery and then flashed the poor bugger with OpenWRT, which according to OpenWRT is still not supported by them for the version 2.2 Linksys, which I subsequently found out I was using! So alas, all that remained was a perfectly dead Linksys, not responding to anything. It was time to go in, screwdrivers a blazing. I shorted out pins 15 and 16 and started up the Linksys, this created a crc error which was detected on boot, this then started up an emergency TFTP server which allowed me to ping and finally tftp the original Linksys firmware back onto it!

More details on the recovery processes can be found here:
