[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Gotnitro:
audit13, I am glad to say my phone is back running!! I would like to thank you so much for your time! Even though I didn't use your method I still very very much appreciate all of your time and I hope good things come in your life! You're a good person, it's very kind of you to help me out and spend your time helping. After speaking to W0lf via Youtube we talked about your method which I was about to do this he mentioned a file manger that can access the system files. I was all over that like a duck on a june bug. Ever since the start I have been suggesting it and asking how but everyone was wanting to seem to flash a rom. I am gonna put the steps that I used to fix my phone in case someone comes across this thread some day.

After doing some research I found that some root font changers replace default fonts located in (system/fonts) so if you ever by chance set a font using root and its a bad font and your phone goes into bootloop (stuck at your carrier logo) then what most likely happen was the font changer set one of your default fonts to a custom one that you selected. You can try to wipe the data via stock recovery. If that dont work then it means it replaced one of your default fonts with a custom font. By doing a factory reset your phone will revert back to the default font, well thats the issue... since you used root permissions it set the default font and replaced it with a custom font. Meaning a datawipe/factory reset isnt gonna do a thing. Here's the steps I used to fix my issue.

Step 1:

Flash a custom recovery using Odin (I used clockwork mod)

Step 2:

Download a file manger called Aroma, place the download on your SD card in a easy folder to find. (leave it as a .zip)

Download Aroma from here : http://xdaforums.com/showpost.php?p=25911284&postcount=2

Step: 3

Ok, depending on your phone you're gonna need to find out what the default fonts are for your device, download the fonts needed and place them on your SD card in a easy to find folder. On the Galaxy S3 I found that DroidSans.ttf and DriodSans

-Bold.ttf was the default fonts. As soon as I replaced these the phone booted right up!

Step 4:

Boot into recovery (power + home + vol up)

Step 5:

Pick mount and storage > mount /system > Go back > install zip > choose zip from /storage/sdcard1 (should be named Aroma)

Once Aroma has been opened search for a folder named "storage" then "sdcard1" from there find the folder that you placed the new fonts in. Select both fonts and copy them. Now keep tapping the back key until you return to the main menu. Now opened a folder called "system" then opened a folder named "fonts" then just paste the fonts into this folder. A message will come up saying that files already exists. Just simply tap "overwrite". After this is done tap "menu" then "exit"

Step 6:

Pull your battery and turn your phone as your normally do. I do wanna let you guys know, when I did this it just was stuck at the boot screen like it was still boot looping, I was mad and just put the phone beside me and started searching for other fonts and next thing I know my phone is at the home screen. So for the first time it could take awhile, give it 5 mins to be safe!!!

I hope I explained well, its 3 am here and I just got mine fixed minutes ago and I felt that I should put this here in case someone needed it.

I would also like to mention a person named W0lf, he has helped me out so much I cant thank him enough,
