[Motorola Droid RAZR] Ohmster:
DumbleCore is right, you can download and install Super SU from the play store and it will ask for root permission, you give it always, and it is your new SU. But the remaining one is still there and built into the rom. Although they both work, they give conflicting update messages if you tap the app itself. Super SU will insist on updating the su binary, which is "outdated", tries to install it, fails, and gives the same message if you check. Super SU will also allow you to do the su binary update in recovery, but I would not do it. Every update comes with superuser built in and that is another layer of hassle you will deal with on every update if you try to maintain it.

You can do it, it will not hurt anything. But tapping the Super SU app and checking the status of the su binary will fail and it never satisfies itself with the update. You will get notification toasts telling you the su binary is out of date. You can ignore them and everything is fine. Or try to update in Super SU and I have yet to see it work. Titanium Backup always tells me to use Super SU instead, but it works fine, regardless. You can dismiss the message in Titanium Backup and never have to see it again.

Oh boy, I *hate* to sell out cm11 because I love it, I really do. This issue is in all the 4.4 roms, at least for CyanogenMod. 4.3 does not seem to be afflicted. I would suggest you use two roms, one stock for driving, another rom where Bluetooth does work and I cannot give you a Kit Kat rom that does work for sure, ask around. Jellybean does not have this problem and I keep a JB rom in my stock slot and use it when cm11 gives me problems until I can fix it. My stock rom is Matt's Utility, because it is not too hard to install via USB in AP Fastboot mode, is Jellybean, always works, and comes with a rooting utility so you can root it at the same time. Would that wipe out your Safe Strap and current rom? Probably, so don't use it unless you really mess up the phone, I would say. But this utility is a lifesaver, download or bookmark it anyway. I get out of semibricked phones with it all the time and that has not been for a while now. ClockworkMod ROM Manager will wreck your phone and this will get you out of it.

Make a Safe Strap backup, use a File Manager and find it under /TWRP and copy that backup to cloud like Dropbox or to PC with USB cable so if you do wreck your phone, you at least have a SS backup you could use, after rooting your phone on the new rom.

This person in his post reports that Liquid Smooth works in Bluetooth and he gives some details. Read it.

Cm11 will have to work this bug out by Final or even Release Candidate, so, sooner or later, probably later, it will be addressed. Otherwise that is a big black eye for cm11. Stargo needs a sympathetic developer at Motorola to leak the code or reverse engineer the A HAL layer, wow! So use your stock rom for driving, and your cm11 rom for experimenting, using otherwise, so that you will not miss the fix when it comes out. Else, try Liquid or some other rom, there are quite a few users in here that user liquid, ask them if it has "The Bluetooth Artificial Speech distortion" problem first. But I think a dual boot rom would be best for now. It is a matter of how bad you need this and how much you want to put up with. For all I know, it could be fixed in days, but I doubt it. Wish I had better news. :(
