OK, so I've had an EVO flashed over to Metro, Rooted (S-Off) & running Metrodroid 2.2, setup by someone else, for a couple of months now.
I'm not sure all the EPST settings are correct, but, for the most part, it is functioning with voice text & web, nominally.
So, I know there's no way to use EVO's 4G WiMax radio, on Metro, because of the frequency difference, between it & Metro's 4G-LTE system. And, there's no such thing as real 3G either, so, we're just stuck with 1X RTT.
I'm questioning if other settings like, can I safely update, the Radio's, the NV, PRI, &, Hboot, without loosing the settings in Metrodroid that allow MMS to work, and would it improve the situation?
I can live with most of this (at least a while longer), but, the 1X D/L speed, is really tanked.
Even with greater than 3 bars of available signal, it' remains less than 10Kbs at best download, yet the upload gets upward of 40Kbs. I feel I've reached my level of incompetence, and don't know which way to go.
