Shamelessly stealing @MJHawaii instructions from this thread (THANK YOU):
(DISCLAIMER) Please read and follow the instructions carefully. I nor anyone else on this forum is responsible if you brick your phone, lose your job, or life as you know it ends. Make sure you fully Understand what you're doing before you do it. Modifying any phone comes with a risk.
WARNING: Please do not flash this if you're low on battery...go charge your phone!
o) Download the I9505GUEUCxxx_FULL_ROOTED.tar.md5.gz package from below
o) Make sure you have the USB Drivers installed and you have Odin 3.09 from below
o) Put your phone in download mode and connect it to USB:
-Disconnect the phone from USB
-Power OFF your phone
-Hold Volume Down, Home, and Power
-When the "WARNING!!!" screen comes up, release the buttons
-Volume up to enter download mode
-Connect the phone to USB
o) Open Odin
o) Click on AP, then select the I9505GUEUCxxx_FULL_ROOTED.tar.md5.gz package you downloaded
o) Odin will extract the tar md5 file from the gzip archive, and this will take a while...be patient
o) Once the tar md5 is loaded, make sure you have a COM PORT in Odin ( any )
o) Click Start and wait till it finishes flashing...your phone should reboot when it's done
NOTE: If your phone does not boot, then boot into stock recovery and Wipe Data Factory Reset.
A GIANT thank you to @MJHawaii for helping me learn this process!!!
