You need to use the bluetooth fix here. Just flash the zips in cwm.
[ROM][Sprint/Boost] CTMod 3.75 Final (11/18/12) - Page 31 - Android Forums
Alright, so here's the big question... I'm not noticing any bluetooth problems on my Marquee using the new beta kernel and 3.75 final (I use a Jabra Drive device). So if it ain't broke, don't fix it, right?
Also, I'm looking for a good Marquee overclocking for dummies resource... what can the Marquee be safely overclocked to (where you see performance benefit, but are still within safety margins). I've been a little scared of tinkering with the "Voltage Control" app that came with CTMod. Or, should I overclock with CPU Controls in Rom Toolbox Pro? Quite frankly, I'm not sure what I'm looking at other than the min/max Mhz speed. (Governor? I/O Scheduler?)
