You should update your radio to 1204.105, that could be one of the reasons for #1. Just flash any boot.img from 1.29.401.11 stock roms.
Yeah it's weird but that's how it works, totally different from old HTC phones. Try it out, just flash a boot.img from 1.29.401.11 and reflash your own boot after, you'll see the radio is updated.From my limited research flashing the boot.img doesn't update the modem, its in the system/etc, but I'd love to be corrected, I want to provide the latest modems.. any one help?
Someone already figured out the radio on the 1X is stored on file QUO_6260.fls.clean on /system/etc lol weird stuff.This didn't work for me, unless Im not flashing the right boot.img, when I do so the phone will come up but show's no baseband, when I flash mine back works fine but still the old baseband. Can you dropbox the a boot.img for me to try?
