I recently received a HR10-250 and it has software v6.3d but i can't find any info on this update version. Most posts deal with a or b. I want to hack to get network access and TivoWebPlus. Any ideas where to find the changes and upgrade process? DVRUpgrade IC appears to refer to 6.3a. I don't know the history of this box but seems like backdoors are enabled since 30 sec skip, NP sort and on screen clock codes work.
