I have a potential, albeit "dirty" (won't survive firmware upgrade, for example) solution for E4 cams that came with 2.3.0. It gives upgraded resolution _only_ (for now). But before widely releasing it, I'd like to test it on a few more devices.
So if anyone
- feels adventurous (although unlikely, it could simply not work, or even brick your camera, or maybe create a black hole and swallow up earth),
- has an E4 that _came_ with 2.3.0 (though it should work with upgraded units too, but let's start with known facts),
- already has experience with the Flir E4 (including setting up RNDIS mode, ftp access, telnet)
please send me a PM and I'll supply you with a tool. I promise(*) that once the hack turns out to be useful I'll publish it here.
(*) You should not believe any promises from random strangers on the internet.
