Beats Patch has the following negatives.
1) Camcorder both in C.M 7.2 and Stock 2.3.3 fail after applying beats audio patch (any for that matter).
2) Cannot work with DSP Manager.
3) Equalizer fails to load, but Power Amp works (with v314.....not with Dhruv's patch)
4) With Dhruv's patch: Camcorder, DSP, Equalizer and Power Amp...all do not work (DSP is erased with this patch).
5) Once you install this patch, even if you go back to v314, it does not correct the damage already done by this patch and even the working Power Amp fails.
So install Beats only if you are willing to sacrifice all the above...
