Well, this one is definitely an interesting development for those of you who own a Samsung Galaxy S III, especially if your phone is rooted and you don’t mind testing out a custom ROM or two. XDA Member cpu999, or as we know him, David H. from Google+ has released an interesting new script that allows you to port custom ROM’s developed for one specific carrier’s variant of the device to another carrier’s variant.
So, let’s say for instance you want to rock Frosty JB, the ROM I use as my daily driver on my T-Mobile Galaxy S III on your Verizon Galaxy S III, this script will make that possible, but unfortunately there are some limitation that we need to note up front. First, this is only for United States carrier variants of the S3 — it is not compatible with the i9300 (international). Also, this script only works in Linux. David has stated that he will be working on a Windows version, so if you’re not running Linux, you’ll have to hold off for now.
If you meet the requirements, here’s what you’ll have to do:
1. Download the ROM you want to port and a ROM on the SAME Android version as the ROM u want to port
2. Unzip both of them and place both folders in the same folder
3. Download the script and place it in the folder with the two rom folders
4. Open a terminal and cd to the directory
chmod +x portscript.sh
Another thing I’d like to point out is that we’re not sure if this works or not. I don’t have a Linux box to test it out myself, so you can feel free to try it out if you like, or pass up on it if you’re leary. If you decide to take the plunge, the files you need can be found in David’s original thread on XDA.
Keep in mind, we’re not responsible for anything you do to your phone, so be sure you’re comfortable with what you’re doing before you do it!
Be sure to stop back and let us know how it works out for you if you try it out!
