How to Solve a Hardware Error 51
From DVRpedia
Overview
After restoring the backup image of one TiVo to another TiVo, a hardware 51 error can occur. To resolve this problem, a Clear and Delete Everything can be performed to resolve the problem, but this will also delete all recordings and season passes. This can result in no networking on a modified TiVo. This page describes how to solve the "Hardware Error #51" without performing a "Clear and Delete Everything".
Applies To
All TiVos
Details
Install the script AlphaWolfs 51killer.tcl on your TiVo and run it to perform the same actions as a Clear and Delete without breaking networking. This script will also solve a "Hardware Error 51" problem that occurs when installing a backup image from another TiVo into a different TiVo.
The scrip is available on this DealDatabase thread: http://www.dealdatabase.com/forum/showthread.php?t=25984&highlight=51killer.tcl
