Fix for unlocked bootloader only!

Boot images for XT926 and XT907 stock kitkat:
XT926: http://d-h.st/vre
XT907: http://d-h.st/KXA

Both boot images contain the recompiled stock kitkat kernel with increased sleep time after lineout PA enable, as in this commit: https://github.com/CyanogenMod/andro...435380750bd78e

To be flashed via fastboot:
Code:
fastboot flash boot bootXT926speakerfix.img
or
Code:
fastboot flash boot bootXT907speakerfix.img
Please note that I don't own xt926 nor xt907, so I can't verify that the boot images boot at all, nor that they actually fix the issue.
(xt897 haven't got an official kitkat update yet, and it's possible that it won't happen for Photon Q at all.)
Be prepared to flash the stock kitkat boot.img in case of a failure if you're going to test this. You've been warned.

Please let me know how it works for you, thanks.

EDIT: links updated to correctly re-packed boot images.
xt926 boot image already confirmed to boot fine and fix the issue (by iBolski).

Sorry, I have no idea what flashify app is and does. I'm used to do the flashing from command line.

The boot images linked here are only for the stock 4.4 ROM.
The issue will be fixed directly in the CM11/razrqcom motorola msm8960dt-common kernel in the future.
See my post about it here: http://forum.xda-developers.com/show...php?p=53614821

Odd thing, is my black RAZR M whose manufacture date was sometime in 2012 didn't have this problem at all. No popping whatsoever. However, my white one with manufacture date sometime around 5/2013 did have this problem. Makes me wonder if the hardware was updated in some minor way.
