Unhappy [Q] 4.4.2 ExtSDCard Fix Doesn't Work

Hey everyone,

After updating to 4.4.2 I had the SD Card Write problem that other people have been having, and I looked around and found two threads here with a guide to fixing it.

This one :

and this one :

I tried flashing both the files (Using Philz recovery) but it didn't help.

What's more confusing is that if I try to manually edit my platform.xml file, ES file explorer simply says "Task Failed" when I try to save the edited file or even replace it with a pre-edited one. This is despite granting it root permissions. I thought that maybe my phone didn't root properly, but root checker says it's rooted fine, and I've used Xposed, AdAway, Greenify, and Seeder successfully.

This is the method I used to root and install recovery :

I'm not sure if this is related, but Titanium Backup's freeze feature isn't working for me anymore either. I have purchased the Pro version. It says freezing successful, but it simply doesn't do anything to the app I'm trying to freeze.

Any ideas what's happening here?

As far as I could tell, none of the custom kernels for the I9500 are stable. I need my phone to be rock solid (that's why I'm sticking to stock as well) so can't afford to flash a custom kernel.

Any alternate solutions anyone? And any idea what's causing this in the first place?
