I have a Xperia P. I changed build.prop files and my device has been stuck in a boot loop ever since then the stock Sony reset wont boot the device into recovery neither will my custom clockworkmod recovery. I do have knowledge about this problem but no practical experience I have never flashed the device, its stock. I need help to recover and then to reset the .prop .
or otherwise is there a way to delibratly brick my phone and then ill bring it to my carrier and try to spoof my warranty. Stock Android 4.1.2 rooted, bootloader is unlocked.
