First I would like to thank you for reading this post and helping in anyway you can!
So I have an S4 on Verizon here in the USA. I just received the update OTA for 4.4.2 about a month ago. I didn't like some of the changes, I was considering going back to 4.2. but unsure of what it would involve. A few weeks later i purchased a new radio for my truck, its a pioneer with AppRadio mode. After hours of unsuccessful attempts at getting the phone to work with the deck I decided to call pioneer tech support. They informed me that there AppRadio mode will only work with the S4 on 4.4.2 , only 4.2 or 4.3 (possibly). So now I had two reasons to try to revert to factory firmware. So after some research I decided to tackle the task. I found a tutorial to install factory firmware using the Odin program from a PC. I was under the impression that I needed to ROOT my phone in order to install an firmware manually. So I followed another tutorial on how to ROOT the S4 on Verizon with 4.4.2 and it worked, I has super user access. So now came the flashing process. I restarted the device, holding the volume down / power / home button to enter the download mode. I then connected the phone to the PC with the proper USB drivers installed and Odin 3.07. The device showed up as COM ID 007 in the blue box. I then downloaded the .tar.md5 file from the website. I loaded that by pressing the PDA button in Odin. After a minute or so it finished checking the MD5 successfully, I clicked start, a few steps occurred followed by the red FAIL box in Odin. After multiple attempts it still did not work. I now have a non working phone! I can enter the download mode fine, but when i power on normally or into the factory recover I get the message saying that the firmware upgrade failed and to use kies to try to fix the problem. I downloaded keys, still nothing. What am I doing wrong? Can I not go back to 4.2 since I upgraded to 4.4? I just want my phone back to working condition at this point, unless someone can tell me a way to go to 4.2 that will work.
Again thanks for the help!
