Speaking of backups ...
I stumbled across the E4 info by purest luck and managed to get one of the last 1.19.8 units from TEquipment.net. Resolution mod is working great and I think that I managed to make enough of a backup of the file system using RNDIS and FileZilla. Lots of errors reported during the copy, however; presumably, these were FS locked files, so no problem?
Anyway, by the time I opened the box, the FLIR site only had the 1.21.0 "update pack" on their site. The good lord willin' and the creek don't rise, I'll never need to reflash the unit with 1.19.8 but... Is there any archive out there that has the 1.19.8 firmware for a just-in-case backup?
