We have an IP500v2 on R11.0 that we are going to be upgrading to R12.1. Unfortunately the system is remote for me; so re-creating the SD card is not an option, and I will have to upgrade it via Manager upgrade option. I know the upgrade can take some time because of all the different language files it uploads - so my questions is / what can i do to remove all the unused language files (only need US-English) prior to performing the upgrade, so that it doesnt upload all the unneeded languages / as well as speed up the upgrade? Any information is greatly appreciated. Thanks,
