Stock MMS app for non-stock KitKat topic

Hi,

I just replaced my nexus 5 for a galaxy note 3 but I basically prefer stock google apps so I'm replacing samsung apps for stock ones when possible, first things first I wanted the stock MMS app back cause I don't like hangouts too,
as samsung is naming their apps the same name as google it's hard installing stock ones without root (and removing the samsung version first), as a solution I renamed the app so it can be installed without conflicting with samsung app

basically here's what I did :

- extracted the MMS app from the Android SDK image
- deodexed
- decompiled
- renamed all occurences of com.android.mms to com.android.stockmms
- renamed all occurences of com/android/mms com/android/stockmms (in smali stuff)
- renamed occurences of mms_temp_file to stockmms_temp_file
- recompiled

I tried the same on contacts (people) app but there's a problem with a shared certificate with android.uid.shared and the app will not sync with user account contacts or something

Here's the mms apk (4.4.2-938007):

[Q] Camera Firmware app on non-stock ROM topic

In stock rom there is application to check camera firmware (*#34971539#). Can this application be ported to non-stock rom, for example CM?

Having problems with all non-stock ROMs. topic

So, I got an S3 some time ago, and I found stock gross and ugly. So I tried CyanogenMod, which started having random reboots and freezes, a certain game (The Room) would consistenly hang, and when I bought an SD card for it, it would pop up constant notifications of "Preparing SD card" and then "SD card removed unexpectedly". I switched to CyanFox, which had the same SD card issues until I formatted it to exFAT. That too started hanging and restarting randomly. I flashed stock back on, deleting everything as far as I know, and that seemed to work fine (although I didn't try it for too long, only a few hours), but it was still gross, so I tried CyanFox (same problems), ParanoidAndroid (same problems, and then finally LiquidSmooth which worked absolutely fine at first and then soon after would hang if I tried to shut it down, and then after that, would start having the SD card issues. I'm thinking it might be something with the few apps I'm loading on (IM+ Pro, MyFitnessPal, Play Music, Chrome, ES File Explorer), and maybe the SD card issues are only with this single card, because only just recently did I get a second card, which actually doesn't seem to be having problems, but either way (and also TL;DR version):

CyanogenMod 10 is crashing and hanging
CyanFox is crashing and hanging
ParanoidAndroid is crashing and hanging
LiquidSmooth won't shut down properly

I'm using the latest CWM touch (although I've tried flashing with TWRP and it didn't fix anything), I haven't been restoring backups when switching ROMs, and I just can't figure out what's doing this.
