Help "Broken" LG Optimus F3 vold.fstab file

[asdfmang1]

So basically I was trying to switch my internal sd card with my external sd card because this phone has practically no storage space for apps, music, and whatnot. I followed a tutorial I found online to edit the vold.fstab file by replacing "sdcard0" with "sdcard1" and vice versa in the file. After rebooting my phone, I found I was unable to access many features of my settings application such as storage or the computer connection type. I then looked around online for a solution and found that I need to flash a new stock rom for my phone. The main problem is I can't find a stock rom for this phone anywhere online. So in short, if you have a stock rom for this phone, please post a link for me to download it as it has been a hassle trying to find one. I would also appreciate it if you had another method of fixing the vold.fstab file so I don't have to reset my entire phone.

Here's the exact model of my phone:

LG-P659 T-Mobile
Android 4.1.2 Jellybean

(Also I am rooted through saferoot)
