After having some fun with CyanogenMod I decided to try out the PAC rom. Following the installation instructions on their mod page I wiped the internal data of my phone but what as I was sliding the confirmation I realised that 'system' was checked. Too late
I have read through countless threads on this sight and others but have not had any success.
I have located the stock recovery image for my device.
When my device is first switched on I can still hit volume down + power button, and then volume up to enter the downloading mode (but if I don't the booting begins to loop at the Samsung Galaxy S4 logo and goes no further). Odin still recognises my phone and allows me to flash roms but when it does the auto re-boot at the end I don't have a system and it gets stuck on the booting at the Galaxy S4 logo.
Several threads have suggested that I Fastboot, I'm not sure if this is even an option with the S4 or not but please let me know if it you're sure that it is. I have been unsuccessful with my Fastboot attempts so far but if I just need to persevere with it then I can.
Any insight would be greatly appreciated
